57. Top graph: NOAA (2019); right section: Met Office Hadley centre (2024), matching the bottom graph. The white 'clouds' indicate the confidence margins, with the two dashed lines representing the P_2.5 and P_97.5 intervals: the area between them thus encloses the 2σ confidence interval. Lower graph: Met Office Hadley centre (2024). The data for 2024 is an estimate, published in November 2024: Copernicus Climate Change Service (2024).
58. Except by some institutions and individuals, 'climate deniers', e.g. Smith (2021), who use pseudoscience (Kaufman & Kaufman, 2018; Dutch: Hulspas & Nienhuys, 2021) and science denial (Hansson, 2017) to try to prove otherwise. This is often done in collaboration with extremist political movements and paid lobbyists (Michaels, 2020; Oreskes & Conway, 2010 plus the documentary based on it: Kenner (director), 2014). In many cases, this is combined with all kinds of conspiracy theories and various 'proofs', e.g. that smoking is not bad for health (Hulac, 2016). For an overview, download Appendix 7 of Roorda (2021, Dutch) or Roorda (2022, English).
59. De Glossary van IPCC (2018) defines: “Pre-industrial: The multi-century period prior to the onset of largescale industrial activity around 1750. The reference period 1850–1900 is used to approximate pre-industrial global mean surface temperature (GMST).”

118. Thorium can be used as well. This is not itself fissioned but converted into uranium-233, which can be used as fission material.
119. More precisely, fusion reactions use deuterium and tritium, two isotopes of hydrogen. Hydrogen in nature consists of only a small percentage of deuterium, but so little is needed for large energy generation that the water in rivers and seas provides more than enough raw material to keep energy production going for billions of years without a risk of water shortages. Tritium is grown in fusion reactors from lithium.
120. Nuclear fusion produces significantly more radioactive waste than nuclear fission, but of lower hazard: Gonzalez de Vicente et al (2022). For an overview of the disadvantages of nuclear fusion as an energy source, see Jassby (2017).

Ecocide is defined as: “unlawful or wanton acts committed with knowledge that there is a substantial likelihood of severe and either widespread or long-term damage to the environment being caused by those acts”, where: Wanton = with reckless disregard for damage which would be clearly excessive in relation to the social and economic benefits anticipated; Severe = damage which involves very serious adverse changes, disruption or harm to any element of the environment, including grave impacts on human life or natural, cultural or economic resources; Widespread = damage which extends beyond a limited geographic area, crosses state boundaries, or is suffered by an entire ecosystem or species or a large number of human beings; Long-term = damage which is irreversible or which cannot be redressed through natural recovery within a reasonable period of time; Environment = the earth, its biosphere, cryosphere, lithosphere, hydrosphere and atmosphere, as well as outer space.

170. Thanks to the logarithmic scale, you can achieve the multiplication of world population by per capita production in the graph by adding up the heights - simply in centimetres or inches, for each year separately - of the two curves.
171. Boserup (1981).
172. It is difficult to realistically imagine the collapse of an entire civilisation. Jared Diamond (2005) helps with this, describing how numerous ancient and even more recent civilisations collapsed.
173. Theoretical description: Molina & Rowland (1974), who received a Nobel Prize for this in 1995.
174. Discovery of 'hole' in ozone layer: Farman, Gardiner & Shanklin (1985).
175. Ozone-depleting substances (cause; blue curve, left y-axis): EEA (2020a). Percentages are relative to 1986 values. Extent of ozone hole (effect; red dots, right y-axis): NASA, Goddard Space Flight Center (2022). Shown is the annual largest measured extent, circa September or October. The red continuous curve & transparent red uncertainty area: author's own estimate, matching well with the lower graph in WMO (2022), p. 10.  Background photo: NASA Goddard Space Flight Center.
176. On 9 January 2023, the UN environmental organisation UNEP issued a press release (UNEP, 2023a) stating that the ozone layer is recovering "as expected". The announcement was based on a scientific publication a few months earlier by the World Meteorological Organisation (WMO, 2022), which noted: the "hole" over Antarctica could be back to 1980 levels, i.e. largely (but not quite) gone, by around 2066. That year is pretty uncertain, WMO said: it could also be 2050 or 2090. Lighter damage elsewhere in the world could be restored around 2040 or 2045, but that year is "very unreliable", the report writes. The WMO article also reported that unrestrained growth of CFCs at 3 to 3.5% per year would have caused additional global warming of 0.5 to 1°C by 2100; we have been spared that thanks to the Montreal Protocol. That beneficial effect is partly due to an addition to the Montreal Protocol: the Kigali Amendment, 2016, which bans HFCs. HFCs do not contribute to ozone depletion, but they do contribute to the greenhouse effect. After the UNEP press release, journalists immediately excitedly went to work. This was not always done carefully; even the reporters of serious news media appeared to have either not read the WMO publication or read it badly. British quality newspaper The Guardian wrote (Milman, 2023): "The ozone layer is on track to be fully restored all over the world by 2040, except in the polar regions." The greatest damage, that over the South Pole, was thus downplayed, and the large margin of uncertainty was hushed up. It was also suggested that expected global warming could now be revised downwards by half a degree or more, which was incorrect. In the Netherlands, De Volkskrant was similarly sloppy (Bolle, 2023): "The WMO expects the ozone layer to be restored in most of the world by 2040." The headline above the Volkskrant article was downright untrue: "Ozone layer restored in 2040". One meteorological institute, Weer.nl, did summarise the WMO article rather drastically in the lied headline "Ozone layer finally almost restored" (Huirne, 2023). Apparently, the word "almost" did not attract much attention, because promptly many on social media chanted that the ozone layer had been restored. Good news, but not true. See also: Kessenich, Seppälä & Rodger (2023).
177. Doyle (1991). Greenpeace (1997) quotes DuPont CEO Richard E. Heckert, who wrote to the US Senate on 4 March 1988 - i.e. after the Montreal Protocol was signed - "DuPont stands by its 1975 commitment to discontinue production of fully halogenated chlorofluorocarbons if their use poses a health threat. This is in line with DuPont's long-standing policy that we will not produce a product unless it can be safely made, used, handled and disposed of subject to appropriate safety, health and environmental quality criteria. At present, scientific evidence does not indicate the need for drastic reductions in CFC emissions. There is no indication of the contribution of CFCs to any observed change in the ozone layer."

181. The uncertainty range of the top graph should actually be shown in the middle graph for each country separately. But that would make the figure too confusing, so for each country/region, only the most likely value (the median) is shown.

188. Meadows et al (1972). The team built on Jay Forrester's (1971) dynamic models.
189. Malthus (1798). The mass genocide in Rwanda in 1994 is sometimes seen as a contemporary example of a (Neo-)Malthusian collapse on a regional or local scale, see André & Platteau (1998), Diamond (2005, chapter 10) and Yanagizawa (2006), although there were other causes of the complex tragedy besides Malthusian overpopulation and food scarcity: see Boudreaux (2009), Verpoorten (2012) and Mitton (2022). What Malthus did not foresee was that the systemic limits do not arise only from limited production capacity of food and of raw materials for clothing, housing, transport, industry. It is not supply that turns out to be the main problem, but disposal. The most severe system limits are linked to nature's limited capacities to process our waste and emissions and repair the damage we do: deforestation, environmental pollution, the greenhouse effect. In 1968, Paul Ehrlich published a book, 'The Population Bomb', which also warned of the dangers of overpopulation and famine. His book can be seen as a predecessor of Meadows' 'Limits to Growth', but not yet equipped with a comprehensive computer model that allowed complex quantitative scenarios to be worked through.
190. First update of the model: Meadows et al (1992); second update: Meadows et al (2004).  Bardi (2008) described the eventful history of Limits to Growth (Meadows et al, 1972). Bardi (2011), Turner (2012), Turner (2014), Herrington (2021) en Tielbeke (2022) compared the model with the data available at the time and concluded that developments at those moments best matched the catastrophic BAU scenario.

198. A few examples: the isotope europium-155 halves in about 5 years; samarium-151 in about 90 years; technetium-99 in two hundred thousand years; iodine-129 in 16 million years. After one half-life, the amount of radioactive waste is halved. This does not mean that everything is gone after another half-life, but that half of half remains: it is an exponential decrease. After ten half-lives, the amount has decreased to about one thousandth of the original amount, because 2¹⁰ = 1024.

202. World Nuclear Association (2022). Sweden: Swedish Ministry of the Environment (2022), p.5.  The Netherlands: COVRA (2018), p.21. That report also writes (p.14): "By 10,000 years, most of the short-lived radioactivity (...) will have decayed in-situ." "Around the end of [the 100,000 year] period, the radiotoxicity (...) will be close to that of the original uranium ore from which it was manufactured." France: NEA (2008), p. 6. The 500-year period expected here was applied in the figure. United States: DOE Guideline 960.4-2-1. DOE (2001), p. 18. "DOE would disqualify a site if the pre-waste emplacement ground water travel time from the disturbed zone to the accessible environment is expected to be less than 1,000 years along any pathway of likely and significant radionuclide travel." IAEA (2014): section 4.24, 5.3, I-14. The concept of "several thousands of years" has been interpreted as 3,000 years, i.e. up to the year 5000. Next ice age: Ganopolski et al (2016).
203. ‘Deep Time' was introduced by McPhee (1981). He wrote: "Any number above a few thousand years - fifty thousand, fifty million - will paralyse the imagination almost as much." Ialenti (2020) applies the concept to the future of nuclear power and radioactive waste storage. See further Gordon (2021), and of course all sorts of science fiction novels that practice deep time.
204. Tainter (1988), Diamond (2005), Harari (2011-2014), Van Bavel (2016) and Graeber & Wengrow (2021) describe or mention, e.g., the collapse of the Akkadian Empire in Mesopotamia (now: Iraq and Iran, 22^nd century BC), the Ancient Empire (Egypt, 22^nd century BC), Harappa Indus Valley (India, 19^th century BC), Minoan Crete (16^th-15^th century BC), the Hittite Empire (Turkey, 12^th century BC), the Mycenaean Civilisation (Greece, 10^th century BC), China of the Zhou Dynasty (5^th-3^rd century BC. ), the Roman Empire (5^th century), the Islamic Abbasid Empire (13^th century), the Greenland Vikings (14^th century), the Khmer Empire (Angkor Wat, Cambodia, 15^th century), Greater Zimbabwe (Africa, 15^th century), Pitcairn Islands (Oceania, 15^th century), the Mogul Empire (India, 19^th century), the Fulani Sultanate (West Africa, 19^th century), the Ottoman Empire (Turkey, 19^th-20^th century), Rwanda (Africa, 20^th century), the Soviet Union (20^th century). In North and South America: the Moche IV civilisation (Peru, 6^th century), the mighty Maya Empire (Central America, 9^th and 10^th centuries), the Tiwanamu Empire (Bolivia, 11^th century), the Chaco Anasazi (Southwestern US, 12^th century), the Hohokam (Arizona, 15^th century), the Mississippi Culture (15^th century), all before the arrival of Europeans.
205. Drace, Ojovan & Samanta (2022), p. 10, wrote: "The social and political environment may change dramatically in the future. Moreover, a lesson from the past is that serious economic setbacks and political or social changes cannot be ruled out in the distant future. Estimating the cost of future liabilities contains significant uncertainties as they are projected into the future over many years. There are large time differences between the receipt of revenues from which the costs of nuclear waste management are to be covered and the actual costs incurred."
206. A warning text that has been suggested (Trauth, Hera & Guzowsti, 1993, p. F49-F50) reads: “This place is a message... and part of a system of messages... pay attention to it! Sending this message was important to us. We considered ourselves to be a powerful culture. This place is not a place of honor... no highly esteemed deed is commemorated here... nothing valued is here. What is here was dangerous and repulsive to us. This message is a warning about danger. The danger is in a particular location... it increases towards a center... the center of danger is here... of a particular size and shape, and below us. The danger is still present, in your time, as it was in ours. The danger is to the body, and it can kill. The form of the danger is an emanation of energy. The danger is unleashed only if you substantially disturb this place physically. This place is best shunned and left uninhabited”
207. Mraz (2018) gives an excellent overview and even looks a million years ahead. Figure 4.12 is reproduced from Van Wyck (2005), p. 73, who refers to US Department of Energy, Compliance Certification Application, Figure IV-3.
208. Some examples of warnings from the Egyptian Old Kingdom, 4500 to 5000 years old: "Cursed are those who disturb the peace of a Pharaoh. Those who will break the seal of this tomb will die of a disease that no doctor can diagnose." (Hawass, 2000). "As for all men who will enter this my tomb, there will be judgement; an end will be made for him. Further, I will seize his neck like a bird; further, I will seize the land; further, I will cast the fear of myself into him." (James, 1953). These warnings were illegible to us until ancient Egyptian hieroglyphic writing was deciphered in the 19th century.

211. On a much smaller scale, societies have already found a sustainable equilibrium, though. Diamond (2005, chapter 9) mentions, among others, the small Polynesian island of Tikopia; the highlands of New Guinea, where humans have lived together stably for 46,000 years; and Japan during the Tokugawa period, which ended due to disruption by Americans and Europeans in the 19^th century.

226. Serfdom: situation in medieval Europe in which tenant farmers were owned by a landlord and bound to a piece of land owned by a lord. Peasants lived off the produce; the bulk of the harvest was handed over to the lord. This distinguished serfs from slaves, who were bought and sold without reference to a piece of land.

228. Lewis (2024); according to EJI; Stevenson (2022) as many as 12.5 million. The history of the transatlantic slave trade has been described by Blackburn (2010), and portrayed in the form of an atlas by Eltis & Richardson (2015).
229. Word usage, Slave or Enslaved: In several languages, the term slave is increasingly being replaced by enslaved person. Many media and journalists, including US National Public Radio (McBride, 2023), use the new Associated Press (AP, 2021) guideline that considers both concepts acceptable, indicating a difference in meaning: slave refers to "a person treated as chattel or property", while enslaved person emphasises that "slave status is imposed on an individual".  This book follows this guideline. In several places, it emphasises the status as chattel or property, and uses the term slave: the other term would be too veiled there. See, for example, chapter 11, which reads, "Where once the rich and powerful regarded other humans as slaves, as their property, i.e. as disenfranchised things".  Wood (2022) put it this way: "Describing someone as a slave does not diminish their humanity. Making someone a slave diminishes their humanity, which is the reason not to do it."
230. The starting point of the Enlightenment is often considered to be the death of the French king Louis XIV in 1715. For the end point, either the beginning of the French Revolution, 1789, the death of Immanuel Kant in 1804, or the end of the Napoleonic Wars in 1815 has been suggested. See: White (2018).

When the producer has put the finishing hand to his product, he is most anxious to sell it immediately, lest its value should diminish in his hands. Nor is he less anxious to dispose of the money he may get for it; for the value of money is also perishable. But the only way of getting rid of money is in the purchase of some product or other. Thus the mere circumstance of creation of one product immediately opens a vent for other products.” Say (1834), p. 138–139.

333. SMART: Specific, Measurable, Accepted, Realistic, Time-bound. (The letter 'A' is often interpreted as 'Acceptable', but it is not established that something is acceptable until it is accepted). The concept of SMART was introduced by George Doran (1981), who originally enumerated: Specific, Measurable, Assignable, Realistic, Time-Related. The term is also known as fit for purpose, with an emphasis on S, M and A.

351. Reliability: the degree to which the results of measurements can be trusted because the measurement method has been carefully established and implemented. Mistakenly, 'reliability' is usually defined as the extent to which measurement results are re-established upon repeated measurement, but that is not a definition but a procedure to determine reliability in a given situation. This procedure is not practicable in the present case, since the unreliable poverty rates of many countries over the past two centuries (up to 1981) cannot be re-measured; the data are simply missing.
352. Also called: hidden or underground economy. IMF (2021), p. 13. The International Labour Organisation defines informal economy as “all economic activities by workers and economic units that are – in law or in practice – not covered or insufficiently covered by formal arrangements, [which do] not cover illicit activities, in particular the provision of services or the production, sale, possession or use of goods forbidden by law, including the illicit production and trafficking of drugs, the illicit manufacturing of and trafficking in firearms, trafficking in persons, and money laundering, as defined in the relevant international treaties”.

355. Consistency means that the different parts of a definition (as here: poverty) and of the measurement methods are consistent with each other, i.e. do not conflict with each other. Somewhat forcibly, in this case, you can maintain that the two targets are consistent with each other, because target 1.2 does not mention the word 'extreme'.
356. Target 1.2 is different from target 1.1 in two respects: not only with regard to a multidimensional, non-financial approach, also with regard to national definitions. Following authoritative sources (World Bank, UNICEF), the multidimensional definition is particularly considered here and in Chapter 10. See: World Bank (2017), chapter 2; Chzhen et al (2017).
357. This involves a combination of concept validity (construct validity: do the criteria measure what is meant by the concept?); content validity (do the criteria include a full description of all relevant aspects, is the 'coverage' complete?); ecological validity (do the criteria reflect reality realistically?); and the lesser-known consequential validity (does the application of the criteria have the intended effects in society?).
358. Opinions vary widely on the question, which SDGs are most important. For instance, a survey of a good number of experts placed SDG 10, less inequality, at number 1 (Leitner, 2017), while a survey of national SDG reports actually ranked SDG 10 as the least important goal (UN DESA, 2019a). In a ranking based on an Ipsos survey in collaboration with the World Economic Forum (Ipsos, 2021), the top three consist of SDGs 2 (hunger), 1 (poverty) and 3 (health and well-being), while Kleespies & Dierkes (2022) refer to several sources, in which one survey identifies SDG 13 (climate) and SDG 3 (health and well-being) as priorities, and another study opts for SDG 2 (hunger), SDG 6 (clean water) and SDG 1 (poverty). This book has prioritised key SDGs, as the text reflects, that is, SDGs whose success is a necessary condition for the other SDGs to succeed.
359. The concept of "developing countries" is not considered correct by everyone, partly because the word unfairly lumps many countries together. See: Barros Leal Farias (2023).

402. In ancient times, sewers sometimes existed, including in Babylonia and the Roman Empire. But an enclosed house-to-house system was only first proposed in London in the 19^th century, and constructed after much struggle. See: Hamlin (1992). In New York, construction of such a system began in 1849.
403. As early as the last decade of the last century, the possibility of a fine-mesh tube network for consumer goods was being studied, although it was not yet focused on connections to each individual house. See: Bangert, Piebenga & Jansen (1998).

415. Factors such as 2, 5 and 20 are more or less symbolic numbers, as quite a few improvements cannot be expressed exactly in a number. Ecological efficiency is sometimes expressed using the so-called IPAT formula: I = P∙A∙t, also known as Ehrlich's 'formula' or Commoner's 'formula': see Ehrlich & Holdren (1971); Barry Commoner (1972). In it, I = Impact (on resource stock and environment); P = Population, A = Affluence (welfare), t = Technology, a measure of eco-efficiency. If I must halve, t must also halve, i.e. eco-efficiency must double because only half as many virgin materials and energy are used and ecological damage halves. If you also take into account increases in prosperity, especially for poor countries, or a growth of the world population, efficiency must be increased by a factor of 4 (Von Weizsäcker et al, 1997), a factor of 10 (Factor 10 Club, 1994), or - if you take both into account - a factor of 20 (Weaver et al, 2000); Quist, 2007). For an overview, see Chertow (2001). These calculations are now several decades old but are still relevant, as the eco-efficiency of far from all products has improved dramatically. There are favourable exceptions: the energy consumption of several products, including refrigerators and houses, has improved considerably.

At the time of writing, the Fit for 55 target for 2040 (90% reduction) was not fixed but recommended by the European Commission in order to meet the (fixed) target for 2050 (100% reduction). Perhaps at the time of reading, the 90% target has since been set. For the curve of the Energy Roadmap in the period between 2020 and 2030, a natural trajectory has been assumed. The same is true for Fit for 55 between the 2030, 2040 and 2050 targets.
429. Fit for 55 owes its name to the 55% emission reduction target. After a different calculation method was adopted in 2023, where carbon sinks are included, a recalculation yielded a figure of 57%. Thus, the adjustment from 55% to 57% is not a tightening of the target. Figure 7.2 shows for 2030 the adjusted value of 100% - 57% = 43%. See: European Parliament (2022).

431. More precisely, GDP grew from $6.50 trillion to $16.74 trillion, i.e. by a factor of 16.74 / 6.50 = 2.575. This increase is real because it has been adjusted for inflation: both amounts have been converted to 2024 dollars. In purchasing power terms, GDP rose from PPP$6.23 trillion in 1990 to PPP$24.44 trillion in 2022, growing by a factor of 3.92. (The numbers are taken from World Bank, 2024a).
432. Emissions fell to 68.3% compared to 1990. So CO₂ efficiency improved by a factor of 2.575 / 0.683 = 3.77. In purchasing power, the efficiency improvement factor is 3.92 / 0.683 = 5.74.

459. The similarities and differences between transitions and transformations are interpreted differently by a variety of authors (see, e.g., Smith, Stirling & Berkhout, 2004 and Anderson & Anderson, 2011), presumably based on different scientific cultures in diverse research communities, Hölscher, Wittmayer & Loorbach (2018) write. Many experts consider the words to be (more or less) synonymous. Following suit, this book does too. Loorbach (2022) writes about "transformative change through radical transitions". Further classifications have been made, e.g. by Feola (2015), table 2, including deliberate transformations, progressive transformations, societal transitions, socioecological transitions, etc.

476. The saying comes in various forms. Bruce Sterling (1994): “Today's solutions are tomorrow's problems.” Peter Senge (1990, 2006), chapter 4: “Today's problems come from yesterday’s ‘solutions’.” Albert Einstein wrote, it is often said, "We cannot solve our problems with the same thinking we used when we created them." And also: "The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking." However, it is unclear whether these quotes are really from Einstein. Calaprice (Ed., 2005) suspects that they were derived by others from what Einstein actually wrote: "A new type of thinking is essential if mankind is to survive and move towards higher levels." (Einstein, 1946).

529. The concept of 'ecological efficiency' was introduced by Schaltegger & Sturm (1990, 1992). There are various definitions of the term; that of Schaltegger & Sturm, or variations of it (see OECD, 2008 and Desli, 2021), is the most common: ecological efficiency is the ratio between economic value added and the ecological impact created in the process.
530. There are several definitions of ecological efficiency (EE), or eco-efficiency for short, which do not agree with each other. This book uses the OECD definition (1998; 2008): "the efficiency with which ecological resources are used to meet human needs. It can be considered as a ratio of an output divided by an input: the "output" being the value of products and services produced by a firm, a sector or the economy as a whole, and the "input" being the sum of environmental pressures generated by the firm, sector or economy." See also: Kuosmanen & Kortelainen (2005). Chapter 9 provides a formula by which the EE thus defined can actually be calculated. But the European Environment Agency (EEA, 1999) and other sources use the concept of 'eco-efficiency' as its desired increase, actually not EE but ΔEE, which is noteworthy from a science-theoretical point of view. The distinction was signalled by WBCSD (2000), p. 8. Still other sources incorporate a combination of economic as well as ecological factors in the definition. To further complicate matters, in contexts where money is spent for the benefit of the environment, EE is precisely defined inversely as the ecological return divided by the financial investment, e.g. Picardo et al (2023).

One method of doing so is the determination of 'willingness to pay' (Loomis & White, 1996; Richardson & Loomis, 2009), which in a survey of the US population was estimated at $12 per household per year per species, yielding a cost due to extinguishing species between $29 billion and $71 billion per year. (Hsiung & Sunstein, 2007; Johnston, 2007.)  Markandya et al (2008) estimated the health benefit to humans of the presence of the vulture population at $2.4 billion per year; see also Johnson & Hackett (2016), p. 36.

Winter en Leenaarts (2015): “When the loan is repaid over time, the money created is withdrawn from the real economy again and the balance between money creation and money destruction is effectively zero. However, that is not all. After all, interest has to be paid on the loan, even though the money was not created for that purpose. This amount of interest has to be raised by the participants in the real economy by generating income. (...) In fact, society has to work harder and harder to accumulate money needed to pay debts and interest. This can only be done if we manage to increase income significantly. (...) Thus, as a society, we end up in a forced situation of exponential growth.”
605. Heilbroner (1953). Beunder (2015): "If savings are not invested, some of the income earned will not flow back into the economy, resulting in a recession." This can only be prevented if savings are used for expansion investments.
606. Kalshoven (2008). Other reasons for necessary growth have been mentioned, such as: increases in labour productivity and healthcare costs (Ayres, 2008; Jackson, 2009); investments related to environmental problems (Lomborg, 2001, 2004); public investment; competitiveness (Mulder & Koster, 2008); poverty reduction, but without redistribution, and therefore growth for all (Joseph Stiglitz, in an interview with Mulder and Koster, 2008, pp. 69-74).

612. UNEP (2010), wherein the following definitions (p. 18-19): Dematerialisation = reduction of the throughput of materials in human societies. Absolute dematerialisation = decrease of the total amount of material inputs in a society. Relative dematerialisation = decrease of the amount of material input per unit of GDP or per capita. Decoupling = reducing the relationship between (1) economic variables, such as gdp or the Human Development Index (HDI), and (2) environmental variables, such as resource use or environmental indicators. Resource decoupling = reducing the relationship between economic growth and the consumption of land, material, water and energy resources. Impact decoupling = reducing the relationship between economic growth and environmental impacts such as climate change, biodiversity loss and degradation of human health. Relative decoupling = positive growth of the environmentally relevant parameter, but less than the economic parameter. Absolute decoupling = zero or negative growth rate of the environmental parameter.
613. Indicators have been developed for that purpose, including the Domestic Material Consumption (DMC), see Voet et al (2005). Dittrich et al (2017) observed, "In a global perspective, most countries showed either no decoupling or 'relative decoupling' for the period under study. Only a minority of countries, including Germany, Italy, Japan and the UK, achieved 'absolute decoupling', meaning a decline in DMC in absolute terms. However, this does not necessarily mean that these countries achieved 'green growth'. On the contrary, this performance may also or partly be due to outsourced material-intensive production and thus to a shifted environmental pressure, which is ignored by the DMC indicator."

It is something that happens inside you: a decision you make and then act upon. Accountability is something you give to others. Accountability is something that happens from you to the outside world, and not just in the form of one-way traffic to the outside world, but in the form of a dialogue.

Meanwhile, slavery in prisons has recently been outlawed by law, except in Louisiana; so formally, legal slavery still exists in the US.

The standard of living is made up of 6 components, so each weighs 1/18. The exact calculation of the MPI can be found in UNDP & OPHI (2022b).

The World Bank's widely accepted definition describes civil society organisations as: “the wide array of nongovernmental and not-for-profit organizations which have a presence in public life, expressing the interests and values of their members or others, based on ethical, cultural, scientific, religious or philanthropic considerations. This definition of civil society (...) refers to the sphere outside the family, the state and the market. It excludes for-profit businesses, although professional associations or business federations may be included.” World Bank (2005): chapter 2, n0. 6, p.3.

723. The fourth member of the quadruple helix is usually referred to as 'universities'. This book extends this to 'education and research' in general. The quintuple helix has been presented elsewhere in a way where nature is located as one of the five within the helix, see, for example, Carayannis, Barth & Campbell (2012). In figure 10.1, the natural environment is not part of the helix, but rather the helix is part of nature, so that the helix itself is represented graphically as a quadruple helix of human society.
724. Public-Private Partnership is already the third concept to be abbreviated to PPP. Previously mentioned in the book were: People, Planet, Profit and Purchasing Power Parity, both of which are abbreviated to PPP as well.
725. ‘Trans’ = beyond, through. So 'transdisciplinary' means: beyond disciplines. Definitions of these concepts often vary, which can cause confusion. This book uses a coherent set of three definitions: Multidisciplinary: approach where a project or problem is highlighted from multiple disciplines, allowing different types of perspectives and methods to have a chance. Experts are not in close contact with each other, so solutions based on combinations of disciplines are not likely to be created. One person can, without the help of others, do multidisciplinary work. Interdisciplinary: method of team collaboration in which experts from a variety of disciplines work intensively together on a project or problem, enabling rich, creative and innovative strategies and methods to be devised and implemented. Transdisciplinary: method of working together in an interdisciplinary team, which also includes individuals who participate not because of a particular discipline but because of their practical experience or some other form of involvement, e.g. as a representative of a civil society organisation or of nature. See: Roorda (2015, 2016), a further elaboration of Roorda (2010), partly based on RMNO (2000) and Pohl & Hirsch Hadorn (2007).

739. Martin (1966) opened the scientific discussion and identified humans as the cause of the extinction wave. Harari (2011-2014), Andermann et al (2020), O'Keefe et al (2023), Svenning et al (2024) and many others endorse this view. In the Americas, which were populated much later than the Old World, this is relatively easy to verify. As the ancestors of the Indians first crossed North America, the North American horse died out, as did the giant armadillo, mastodon, mammoth, cheetah, lion, giant sloth, camel and numerous other large animal species. It was not just about mammals, as the giant condor also became extinct, as did the sabre-toothed salmon and many other species. (These are respectively: equus scotti, glyptodon, mammut, mammuthus, miracinonyx, panthera leo atrox, megalonyx and camelops. The condor was aiolornis incredibilis, the salmon was named post mortem oncorhynchus rastrosus.) When South America also received human habitation, the South American horse died out there, as did the largest llama, an ungulate, an elephant-like animal, a bear and the sabre-toothed tiger. (Successively: hippidion, macrauchenia, toxodon, stegomastodon, arctotherium and smilodon.) Not everyone agrees with the conclusion on the role of humans; the discussion is conducted in a fierce tone. See, for example, Stewart (2021), who 'exonerates' humans. Others argue for more research: Meltzer (2020), Kopels & Ullah (2024).

For instance, members of the Aranda tribe in Australia knew only the numbers one, two, two-and-one, two-and-two, many. Similarly, the Indians of Fire Island, the Abipones in Paraguay, the Bosmans and Pygmies in Africa and the Botocoudos in Brazil did not count beyond four.

The four-sphere model is taken from Roorda (2021d) and Roorda (2022), where the model is applied more extensively.
751. Memes are concepts passed down from generation to generation in a culture; memes are considered the mental counterpart of biological genes, source of physical heredity. The concept was coined by evolutionary biologist Richard Dawkins (1976).

779. The word theory is used here in the scientific sense. The US National Academy of Sciences uses the following four definitions (NAS, 1999):  “Fact: In science, an observation that has been repeatedly confirmed and for all practical purposes is accepted as ‘true’. Truth in science, however, is never final, and what is accepted as a fact today may be modified or even discarded tomorrow. Hypothesis: A tentative statement about the natural world leading to deductions that can be tested. If the deductions are verified, it becomes more probable that the hypothesis is correct. If the deductions are incorrect, the original hypothesis can be abandoned or modified. Hypotheses can be used to build more complex inferences and explanations. Law: A descriptive generalization about how some aspect of the natural world behaves under stated circumstances. Theory: In science, a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.”
780. In the modern science-philosophical view, it is actually not about checking, i.e. verifying, but rather about falsifiability; but that goes a bit too far for the purpose of this book. See: Popper (1934), Popper (1959), Popper (1989).

Chapter 12

821. SDG Target 14.c contains the only mention towards the future, by citing a UN General Assembly report (UNGA, 2012) entitled "The future we want". Those hoping to find inspired visions of the future in it will be disappointed, as the report offers none, although the term "future generations" is mentioned nine times. The report consists of a long series of concerns, acknowledgements and recommendations for action.
822. Sterling uses the concept bolted on here: Sterling (2004), Sterling (2013).
823. It is a common misconception that goals are formulated by describing the route towards them. A goal is not a process but a state. Even a so-called process goal pursues a state to be achieved (referred to in physics as a state of motion), in that case a state to be periodically reached or improved or permanently maintained over a certain period of time, usually intended as a means or intermediate goal or milestone for a final state to be achieved, which in that context is called a result goal: a concept that is therefore a pleonasm.
824. Roorda (2021d) and Roorda (2022) argue in that context for the establishment of an entirely new science, Omniconomics.

842. A rubric is a tool widely used in contemporary university and vocational education to assess and provide feedback on performance and skills, in the form of a list of criteria, provided with a scale of points or level descriptions from low to high, indicating how well each criterion is met. See: Reddy & Andrade (2010); Stevens & Levi (2012); VU (2023).

846. Some of these criteria are particularly applicable to action research (Rapoport, 1970; Halsey, 1972; Brydon-Miller, Greenwood & Maguire, 2003), case studies (Patton, 2014; Yin, 2017), and transdisciplinary research (Roorda, 2001; Pohl & Hirsch Hadorn, 2007; Scholz et al, 2006). For an overview, see Roorda (2010), §1.4.
