While these short outbursts of optimism usually stay within social media (see, for example, these\u00a0<a href=\"https:\/\/twitter.com\/timparrique\/status\/1556576553173131265?s=20\" target=\"_blank\" rel=\"noreferrer noopener\">tweets<\/a>\u00a0from last Summer), it somehow made it to The New York Times last week (\u201c<a href=\"https:\/\/www.nytimes.com\/2023\/02\/17\/opinion\/economic-growth-green-degrowth.html\" target=\"_blank\" rel=\"noreferrer noopener\">Wonking Out: Why growth Can Be Green<\/a>\u201d). As someone who has been actively researching this very question for the last five years, I think Paul Krugman is wrong and that the argument he defends is not only baseless but also potentially dangerous.<\/p>\n<h3><strong>Sustainability is a multi-faceted challenge\u00a0<\/strong><\/h3>\n<p>Paul Krugman brings two piece of evidence to defend his claim. The first is that air quality in New York is better than in Delhi even though GDP in the United States is higher than in India. This is no proof though and one can easily find opposite cases. According to the <a href=\"https:\/\/www.iqair.com\/us\/world-air-quality-ranking\" target=\"_blank\" rel=\"noreferrer noopener\">World Air Quality Index<\/a>, air quality in Nairobi, Mexico City, and Jakarta is much better than in Milan, Seoul, or Paris, even though income levels are lower in the former countries than in the latter. So, this proves nothing. As\u00a0<a href=\"https:\/\/twitter.com\/PoliticOfNature\/status\/1627295729801736193?s=20\" target=\"_blank\" rel=\"noreferrer noopener\">Andrew Ahern<\/a>\u00a0remarks in his response to Krugman on Twitter: \u201cthe idea that an increase in GDP growth was responsible for higher air quality in New York City or anywhere else completely missed the mark. It is through regulations and prioritizing air quality that better air quality is reached \u2013 not in the hopes that once you become \u2018rich\u2019 you have better air quality.\u201d<\/p>\n<p>The fundamental point is this: sustainability is not only about air quality, carbon, or whatever your favourite indicator might be. It is about all of that together. Arguing that economic growth can be greened by showing evidence of one single impact going down is like bragging about being healthy by showing that one of your arms has lost weight. An economy that deserves to be called \u201csustainable\u201d is one that respects the\u00a0<a href=\"https:\/\/www.routledge.com\/Herman-Dalys-Economics-for-a-Full-World-His-Life-and-Ideas\/Victor\/p\/book\/9780367556952\" target=\"_blank\" rel=\"noreferrer noopener\">scale<\/a>\u00a0of its supporting ecology. Think about the economy as a giant metabolism that extracts resources from nature (water, metals, minerals, biomass, etc.) and generates a number of impacts (greenhouse gases, heavy metals, particulate matters, e-waste, excrements, etc.).\u00a0To be sustainable, every single environmental pressure (both at the levels of extraction and pollution) must not transgress the carrying capacity of surrounding ecosystems.<\/p>\n<p>It has become common to refer to the\u00a0<a href=\"https:\/\/www.stockholmresilience.org\/research\/planetary-boundaries\/the-nine-planetary-boundaries.html\" target=\"_blank\" rel=\"noreferrer noopener\">\u201cplanetary boundaries\u201d<\/a>\u00a0as a simplified framework for sustainability. When the IPCC talks about \u201cstaying within planetary boundaries,\u201d it means that humanity should not cross 9 quantitative thresholds (climate change, ocean acidification, ozone layer depletion, air pollution, biodiversity loss, land conversion, freshwater withdrawals, nitrogen and phosphorous loading, and chemical pollution). These can be downscaled at the level of a single nation. This recent study by\u00a0<a href=\"https:\/\/www.nature.com\/articles\/s41893-021-00799-z\" target=\"_blank\" rel=\"noreferrer noopener\">Fanning et al.<\/a>\u00a0uses a simplified seven-boundary framework to evaluate the sustainability of different countries. As\u00a0<strong><em>Figure 1 <\/em><\/strong>shows, the United States performs rather poorly, overshooting all of its ecological thresholds. For now, what is important is the fact that high-income countries like the US are no pinnacles of sustainability; it\u2019s the opposite, the US is one of the most unsustainable economies in the world (see\u00a0<strong><em>Figure 15<\/em><\/strong>).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1994 aligncenter\" src=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1.jpeg\" sizes=\"auto, (max-width: 580px) 100vw, 580px\" srcset=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1-1.jpeg 1920w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1-2.jpeg 300w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1-3.jpeg 1024w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1-4.jpeg 768w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1-5.jpeg 1536w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1-6.jpeg 1200w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-1-7.jpeg 1740w\" alt=\"\" width=\"580\" height=\"326\" \/><\/p>\n<p style=\"text-align: center;\"><em><strong>Figure 1<\/strong>:\u00a0<a href=\"https:\/\/www.nature.com\/articles\/s41893-021-00799-z\" target=\"_blank\" rel=\"noreferrer noopener\">Fanning et al., 2022<\/a>; data at the\u00a0<a href=\"https:\/\/goodlife.leeds.ac.uk\/national-trends\/country-trends\/#USA\" target=\"_blank\" rel=\"noreferrer noopener\">online platform of Leeds University<\/a>, personal adaptation<\/em><\/p>\n<p>If you want to show that growth is genuinely green, you must bring evidence that GDP has decoupled from\u00a0<em>all<\/em>\u00a0environmental pressures.

He argues that British greenhouse gas emissions have reverted back to their 1850s level (yes, this is not a typo, 1850 as in the Victorian era). Let me start with the obvious. Emissions <em>per capita<\/em>\u00a0are total emissions divided by population. There were 17.9 million people living in the UK in 1850 but there are 66.8 million today, so it is disingenuous to compare individual levels of emissions. What really matters for climate change is national emissions, the total number of tons being emitted into the atmosphere. This is Krugman\u2019s first mistake: British emissions have not gone down but up, increasing from 124 Mt in 1850 to 380 Mt in 2018 (<strong><em>Figure 3<\/em><\/strong>).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1997 aligncenter\" src=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-3-1.png\" sizes=\"auto, (max-width: 580px) 100vw, 580px\" srcset=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-3-1-1.png 1214w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-3-1-2.png 300w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-3-1-3.png 1024w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-3-1-4.png 768w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-3-1-5.png 1200w\" alt=\"\" width=\"580\" height=\"301\" data-recalc-dims=\"1\" \/><\/p>\n<p style=\"text-align: center;\"><em><strong>Figure 3<\/strong>: PIK data,\u00a0<a href=\"https:\/\/www.wri.org\/insights\/history-carbon-dioxide-emissions\" target=\"_blank\" rel=\"noreferrer noopener\">World Resources Institute online platform<\/a><\/em><\/p>\n<p>There is a second problem with Krugman\u2019s argument: the time span is way too long to be meaningful. Assessing the effectiveness of climate policies over centuries is as useful as measuring free diving records in weeks. What we really want to know is whether we will manage to reduce emissions by 2030 or 2050 (the deadlines usually given by climate scientists), and so the best we can do for reliable estimation is to look at what we already managed to achieve in the last 30 years.\u00a0<strong><em>Figure 4<\/em><\/strong>\u00a0shows the evolution of British territorial emissions between 1990 and 2018, a decrease from 603 Mt to 380 Mt.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1998 aligncenter\" src=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-4.png\" sizes=\"auto, (max-width: 580px) 100vw, 580px\" srcset=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-4-1.png 1212w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-4-2.png 300w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-4-3.png 1024w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-4-4.png 768w, https:\/\/www.resilience.org\/wp-content\/uploads\/2023\/03\/Figure-4-5.png 1200w\" alt=\"\" width=\"580\" height=\"304\" data-recalc-dims=\"1\" \/><\/p>\n<p style=\"text-align: center;\"><em><strong>Figure 4<\/strong>: PIK data,\u00a0<a href=\"https:\/\/www.wri.org\/insights\/history-carbon-dioxide-emissions\" target=\"_blank\" rel=\"noreferrer noopener\">World Resources Institute online platform<\/a><\/em><\/p>\n<h3><strong>Don\u2019t forget imported emissions<\/strong><\/h3>\n<p>These are <em>territorial emissions<\/em>, only counting whatever has been produced within the frontiers of a specific nation.

This is like transferring one kilo from your left leg to your right leg and calling it weight loss.\u00a0The structure of a carbon footprint should also inform the way we think about our future capacity to reduce emissions. I often hear that technological progress in rich countries will green production. Even if that were true (I have my doubts, see\u00a0<a href=\"https:\/\/eeb.org\/library\/decoupling-debunked\/$\" target=\"_blank\" rel=\"noreferrer noopener\"><em>Decoupling Debunked<\/em><\/a>), this would only cover a portion of emissions (a maximum of 53% in the UK).<\/p>\n<p>[slide-anything id=&#8217;3472166&#8242;]<\/p>\n<p>On the same online platform used by Paul Krugman, you can compare\u00a0<em>production-based<\/em>\u00a0territorial emissions and\u00a0<em>consumption-based<\/em>\u00a0footprints (<strong><em>Figure 6<\/em><\/strong>). In 2018, British footprint emissions were at 535 Mt, 1.4 times larger than territorial emissions (380 Mt). This alone should tamper our optimism.

But if one uses consumption-based indicators instead, the absolute decoupling disappears: 1 additional point of GDP brings +0.22 points of emissions.<\/p>\n<p>One final observation. Footprints are difficult to calculate as they require sophisticated global models. I can speak for France because that\u2019s a country I know fairly well.

The difference is substantial. The -25% reduction announced by\u00a0<em>Our World in Data<\/em>\u00a0is actually only a -9% reduction, so 2,7 times smaller.<\/p>\n<h3><strong>How much emission reduction is enough?\u00a0<\/strong><\/h3>\n<p>For now, let\u2019s get back to the\u00a0<em>Global Carbon Project<\/em>\u00a0data.
