Climate Justice

What if climate justice means climate delay?

From United Nations declarations to corporate sustainability reports, respect for the goal of ‘climate justice’ is everywhere. The moral rationale is clear. Climate change is full of inequities: the mismatch between those who did most to cause it and those who it will most affect; the financial costs that both transition and adaptation impose on those who can least afford it; the winners and losers within and between countries as we transition the world economy.

But what are the practical implications? Can we fix these inequities? And what does embracing climate justice mean for our collective fight against climate change? Does it unlock new collaborations, or put up new barriers? If we find climate jus­tice considera­tions that are slowing the world’s climate action, what would be the moral case then?

These are uncomfortable questions that are rarely publicly asked. But they are part of an inquiry that we need. Activists for climate justice are the last people to think of themselves as climate delayers – but what if that is their unintended effect?

In this paper, we begin that inquiry with a review of the geopolitical context: where the ideas of climate justice came from, how climate action took on its social agenda, and the risks and challenges this presents in today’s world.

I have previously argued for radical realism to unlock climate action at pace and scale.1 An openness about the role and focus of climate justice is part of that realism.


It all starts in Rio
The year is 1992. The Cold War is over, thanks to the dissolution of the Soviet Union ­– quickly, quietly and unexpectedly – at the end of the previous year. Francis Fukuyama publishes The End of History and the Last Man, celebrating the world’s con­vergence on liberal democracy: not just as a victory in a historical sequence of events, but as the natural endpoint for humanity to achieve.

In South Africa, Nelson Mandela has been released from prison and is in the negotia­tions that will lead shortly to all-race elec­tions. In China, Jiang Zemin introduces the ‘socialist market economy’ as the pragmatic system that will drive the country’s dra­mat-ic economic development. In the US and UK, the socially disruptive, ideological transition to neoliberalism of the Reagan-Thatcher years has mellowed into a more business-as-usual operation, run by succes­sors from the same political parties. The ‘greed is good’ 1980s have given way to the caring, sharing ’90s. Interest in the en­viron­ment, which grew rapidly through the 1970s in the English-speaking world, but plat­eaued through the 1980s, is now at its peak.2

In this uniquely benign moment of togeth­erness, the nations of the world assemble in Rio de Janeiro, Brazil, for an Earth Summit. This is the gathering that, among other things, will establish the United Nations Framework Convention on Climate Change (UNFCCC), the system of governance for how the world will collaborate on its cli­mate action.

Environmental interest is not the only phe­nomenon to peak at this time. Economic inequality among nations is also at its all-time peak. The ‘G7’ is the so-called Group of Seven leading industrialized countries, comprising the United States, Japan, Ger­many, the United Kingdom, France, Italy, and Canada. Around the time of the Rio summit, this group of developed countries, making up just 12% of the world’s popula­tion, accounts for two-thirds (67%) of the world’s total GDP.3 And this inequality is very much on the mind of the host nation for the summit.

‘For us, it was always a good idea to com­bine environmental problems with eco­nomic and social issues.’

Rio is the world’s second attempt at an Earth Summit. The first was in Stockholm twenty years previously, in 1972. The ten­sions of the Cold War at that time limited what the meeting could achieve. There was no mention of climate change or global warming in its Declaration. But it did estab­lish the United Nations Environment Pro­gram (UNEP), together with an agreed set of management principles ‘for the preserva­tion and improvement of the human envi­ronment, for the benefit of all the people and for their posterity.’4 Its formal name (‘Earth Summit’ is a shorthand label) was ‘The United Nations Conference on the Human Environment’.

This time, the name and focus for the con­ference are different. Brazil may have been chosen in part for its pivotal environmental role as custodian of the world’s largest and most ecologically diverse rainforest, but for Brazil itself, its role as a leading developing country is just as important. So this confer­ence purposefully melds together two core issues – environmental protection and economic development – in an integrated approach to sustainable development. This is the ‘United Nations Conference on Envi­ronment and Development’.

The Brazilian Delegation is clear and open about its interest in this conflation:

‘The definition of the very title of the conference – Environment and Develop­ment – met the interests of Brazil and other developing countries. Developed countries would have preferred to ex­clude the issue of development from the title, to allow the conference to concen­trate on strictly environmental aspects based on scientific data and conclusions. For us, it was always a good idea to com­bine environmental problems with eco­nomic and social issues.’5

To achieve this goal, Brazil has worked with the UN over multiple preparatory meetings in a two-year build-up to Rio, to make sure that the development side of the agenda, and particularly the interests of developing countries, will be central. Along the way, the definition of environmental is­sues has stretched significantly since Stock­holm, to include eradication of pov­erty, improve­ment of living and working condi­tions, and protection of health. And the governance has changed too; it has been inten­tionally politicized, as the Bra­zilian delega­tion describes:

‘Working initially from an almost iso­lated position, Brazil ended up getting the negotiations to be conducted under the aegis of the United Nations General Assembly, with its own Secretariat. The initial path was going to put the negotia­tions under the World Meteorological Office and UNEP. This would lead to a “depoliticization” of the negotiation, putting the emphasis on scientific and technical aspects. For a conference ad­dressing the interests of developing countries, it was fundamental that eco­nomic issues were at the core of the negotiation. So getting the decision of the General Assembly was crucial to achieving a result that would be bal­anced, broad, and favourable to our interests.’6

Whereas Stockholm had focused on envi­ronmental protection, Rio shifted the agenda to sustainable development.

Sustainability now means redistribution
What is the relevance today of all this manoeuvring from thirty years ago?

The Rio conference set both the formal gov­ernance and the tone for the world’s collab­orative climate action ever since. And the developing country agenda, led by Brazil, was hugely successful in shaping both. Whereas Stockholm had focused on envi­ronmental protection, Rio shifted the agenda to sustainable development. In the discussions in the run-up to Rio, this had meant recognizing the interdependency between environmental protection and eco­nomic development, and between the inter­ests of developed and developing countries. Developed countries would acknowledge that the approach to environmental protec­tion would have to allow for developing countries’ economic growth, and develop­ing countries would acknowledge that their economic growth would need to accommo­date environmental protection. But the shift coming out of Rio went much further.

First, it blended environmental issues into a broader sustainability agenda, which puts goals of social improvement and environ­mental protection side by side, as parts of one whole. This is the framework that we have since become familiar with, first in the United Nations’ Millennium Development Goals (set in 2000 with targets for 2015) and now in the Sustainable Development Goals (set in 2015 with targets for 2030).  For ex­ample, ‘Ensure environmental sustainabil­ity’ was just one of the eight Millennium Development Goals, alongside others such as eradicating extreme poverty and hunger, and achieving universal primary education. And the specific targets within the goal for environmental sustainability included achieving ‘a significant improvement in the lives of at least 100 million slum dwellers.’7 This target was met through ‘access to im­proved water sources, improved sanitation facilities, or durable or less crowded hous­ing’ – effective solutions in pursuit of this goal, but a broad interpretation of ‘environ­mental sustainability’. The Sustainable De­velopment Goals similarly conflate social and environmental issues.

Rio established a principle that continues to guide how we approach cli­mate justice: ‘common but differentiated responsibilities’.

Secondly, Rio established a principle that continues to guide how we approach cli­mate justice. The first Principle in the United Nations Framework Convention on Climate Change – the key document agreed in Rio – states:

The Parties should protect the climate system for the benefit of present and fu­ture generations of humankind, on the basis of equity and in accordance with their common but differentiated responsi­bilities and respective capabilities. Accord­ingly, the developed country Parties should take the lead in combating cli­mate change and the adverse effects thereof.8 [Emphasis added]

The italicized phrase above sums up three complementary considerations for what is expected from different countries. ‘Com­mon’ refers to the moral responsibility to act, which all countries share. ‘Differenti­ated responsibilities’ says their share is not equal, primarily allowing for different countries’ historic contribution to the prob­lem (their ‘culpability’). ‘Respective capabil­ities’ says their share should also reflect what each can bring to the effort, which de­pends on their capacity as a state (e.g. tech­nology, skills, financial resources) and their natural environmental endowment (e.g. forests and other carbon sinks, terrain and sun/wind for renewables, mineral resources).

Recognizing countries’ ‘common but differ­entiated responsibilities’, some­times abbre­viated as CBDR, means formaliz­ing a redis­tributive agenda in the way the world acts on climate change. Even if intui­tively fair as a principle, it has proved prob­lematic in practice, creating a disincen­tive for devel­oped countries to lead and to com­mit. ‘De­politicization’ has indeed been avoided, just as the Brazilian delegation to Rio intended. The cost of this is that the cli­mate agenda has been politicized, making consensual action harder.

The world has already emitted more carbon since the Rio conference than it did in all the time leading up to it.

The historic responsibility has proved the most challenging part of the principle, par­ticularly because today’s emissions are so high (and still growing) that, even for cumu­lative emissions, the picture can change substantially over a short time. In fact, the world has already emitted more carbon since the Rio conference than it did in all the time (since the Industrial Revolution) leading up to it. Over the 250 years before Rio, the G7 countries were responsible for 56% of cumulative emissions, and China only 6%. But over the thirty years since Rio, the two have been more similar: 31% from the G7 and 23% from China.9 So developed countries understandably question a sys­tem that locks in historical responsibility but discounts future responsibility. If we want to be fair, we need to recognize, as one analyst puts it, that ‘the significantly in­creasing emission of major [emerging] economies today would retrospectively be their historical responsibilities in the future.’10

Whichever way you cut the emis­sions data for the thirty years since Rio, there’s an easy narrative for people in devel­oped countries to shift the responsibility away from them­selves (see charts). Of course, this may not be a fair interpretation; but it is a political reality, and climate action has be­come, by design, a political issue. In this sit­uation, getting the world’s great powers to take on special responsibili­ties may depend on there being either com­pensating privi­leges and rights to attract their self-interest, or a good supply of em­pathy and goodwill. A re­cent global analysis highlights that, un­like in many diplomatic contexts, ‘the cur­rent international climate regime offers great powers few privileges and rights that would balance their special responsibili­ties.’11 Without that quid pro quo, we are re­lying heavily on world-scale empathy. And here, too, the trend since Rio is not encour­aging.

A less empathetic world
That Rio made the progress it did, and set the climate justice foundations it did, re­flects the unique moment in 1992 when the world was simultaneously at its most to­gether politically and most polarized finan­cially. Today the world is more fragmented politically and more equal financially, put­ting a strain on the approach that Rio started.

The political fragmentation is hard to quan­tify, but clearest to see – and most relevant to the argument here – as a shift in mindset. Professor Markus Kornprobst, Political Sci­ence and International Relations Chair at the Vienna School of International Studies, writing for Chatham House, sums up the current state of deglobalization: ‘It is fair to say that in the West today, unlike the 1990s, the scales have tipped towards greater sus­picion of globalized approaches.’12 Tangible examples include ‘Brexit, Trumpism, the Ukraine war, problems with supply chains, the global energy crisis and the past dec­ade’s decline in foreign direct investment.’

The financial equalization of the world may be harder to accept, because the popular narrative suggests the opposite, but it can be measured. Global income inequality at the individual level is estimated to have been falling slightly recently, as a combina­tion of two opposing effects: income inequality between countries has been de­clining, while inequality within countries has been increasing (though not every­where). This is a tough combination for the politics of climate justice. It means that for most of the electorate in developed coun­tries, the increasing income gap in-country makes them feel poorer, while the decreas­ing gap vs. developing countries makes them feel that the beneficiaries are less in need. The issue is particularly acute regard­ing China, which is currently still classified as a developing country by the World Trade Organization, despite its upper-middle in­come status.

It is harder to accept shar­ing wealth voluntarily through redistribu­tive policies when you are already sharing so much involuntarily.

Or take the metric used earlier, that in 1992 the G7 countries comprised only 12% of the world’s population but accounted for 67% of its GDP. Today the same countries com­prise 10% of the population, and less than half (44%) of GDP.13 Of course, that still makes the G7 disproportionately rich. (For comparison, China accounts for 18% of the world’s population and of its GDP.) But the fall from 67 to 44% of world GDP in less than thirty years is something the G7 popu­lations can feel. It is harder to accept shar­ing wealth voluntarily through redistribu­tive policies when you are already sharing so much involuntarily.

When COP27 announced its ground-break­ing agreement on loss and damage, the Wall Street Journal led with: ‘Biden Signs Up for Climate Reparations… The use of climate policy to soak Americans keeps getting worse… Welcome to the latest cli­mate shakedown.’14

Putting the political and financial pictures together, it seems that since Rio, human empathy at a global scale has peaked. To be effective, any approach to climate justice needs to accommodate that shift. The tension is not between societal and en­vironmental priorities; it is between ideals and realities. The danger is that the ideals of climate justice may be unachievable in practice – and that in pursuing them, we risk failing to achieve both those societal goals and our climate goals. This is why we must be prepared to question our assump­tions about climate justice.

The prevalence of the word ‘environment’ in English-speaking books rose rapidly from the mid 1950s to the early 1970s; stabilized for a decade; climbed to a new peak 1992-96; then declined, returning to its early 1980s level by 2018. In part this reflects a growth of more specialized words, such as ‘climate change’, which have grown in prevalence since the 1980s; but even the aggregate of these words peaked in the early 1990s. []
