Climate justice

Climate justice is a type of environmental justice^[1] that focuses on the unequal impacts of climate change on marginalized or otherwise vulnerable populations.^[2] Climate justice seeks to achieve an equitable distribution of both the burdens of climate change and the efforts to mitigate climate change.^[3] The economic burden of climate change mitigation is estimated by some at around 1% to 2% of GDP.^[4][5] Climate justice examines concepts such as equality, human rights, collective rights, justice and the historical responsibilities for climate change.^[6]

Climate justice recognises that those who have benefited most from industrialisation bear a disproportionate responsibility for the accumulation of carbon dioxide in the earth's atmosphere, and thus for climate change. Meanwhile, there is growing consensus that people in regions that are the least responsible for climate change as well as the world's poorest and most marginalised communities often tend to suffer the greatest consequences.^[7][8][9] Depending on the country and context, this may include people with low-incomes, indigenous communities or communities of color. They might also be further disadvantaged by responses to climate change which might exacerbate existing inequalities around race, gender, sexuality and disability. When those affected the most by climate change despite having contributed the least to causing it are also negatively affected by responses to climate change, this is known as the 'triple injustice' of climate change.^{[10][11][12][13]}

Conceptions of climate justice can be grouped along the lines of procedural justice and distributive justice. The former stresses fair, transparent and inclusive decision-making. The latter stresses a fair distribution of the costs and outcomes of climate change (substantive rights).^[11] There are at least ten different principles that are helpful to distribute climate costs fairly.^[14] Climate justice also tries to address the social implications of climate change mitigation. If these are not addressed properly, this could result in profound economic and social tensions. It could even lead to delays in necessary changes.^[15]

Climate justice actions can include the growing global body of climate litigation.^[16] In 2017, a report of the United Nations Environment Programme identified 894 ongoing legal actions worldwide.^[17]

Use and popularity of climate justice language has increased dramatically in recent years, yet climate justice is understood in many ways, and the different meanings are sometimes contested. At its simplest, conceptions of climate justice can be grouped along the following two lines:^[11]

• procedural justice, which emphasizes fair, transparent and inclusive decision making, and
• distributive justice, which places the emphasis on who bears the costs of both climate change and the actions taken to address it.

The objectives of climate justice can be described as: "to encompasses a set of rights and obligations, which corporations, individuals and governments have towards those vulnerable people who will be in a way significantly disproportionately affected by climate change."^[18]

Climate justice examines concepts such as equality, human rights, collective rights, and the historical responsibilities for climate change. There are procedural dimensions of climate change mitigation, as well as distributive ethical ones. Recognition and respect are the underlying basis for distributive and procedural justice.^[19]

Among major emitters, the U.S. has higher annual per capita emissions than China, which has more total annual emissions.^[20]

Cumulatively, U.S. and China emissions have caused the most greenhouse gas-related economic damage.^[21]

Whether fundamental differences in economic systems, such as capitalism versus socialism, are the, or a, root cause of climate injustice is a contentious issue. In this context, fundamental disagreements arise between conservative environmental groups on one side and leftist organizations on the other. While the former often tend to blame the excesses of neoliberalism for climate change and argue in favor of market-based reform within capitalism, the latter view capitalism with its exploitative traits as the underlying central issue.^[22] Other possible causal explanations include hierarchies based on the group differences and the nature of the fossil fuel industry itself.^[23]

It has been argued that the unwarranted rate of climate change, along with its inequality of burdens, is a structural injustice. There is political responsibility for the maintenance and support of existing structural processes.^[24] This is despite assumed viable potential alternative models based on novel technologies and means. As a criterion for determining responsibility for climate change, individual causal contribution does not matter as much as responsibility for the perpetuation of carbon-intensive practices and institutions. These structures constitute the global politico-economic system, rather than enabling structural changes towards a system that does not facilitate exploitation of people and nature.^[25][26]

For others, climate justice could be pursued through existing economic frameworks, global organizations and policy mechanisms. Therefore, the root causes could be found in the causes that so far inhibited global implementation of measures like emissions trading schemes.^[27]

Emissions of the richest 1% are more than twice that of the poorest 50%.^[28] Compliance with the Paris Agreement's 1.5°C goal would require the richest 1% to reduce emissions by at least 30 times, while per-person emissions of the poorest 50% could approximately triple.^[28]

Though total CO₂ emissions (size of pie charts) differ substantially among high-emitting regions, the pattern of higher income classes emitting more than lower income classes is consistent across regions.^[29] The world's top 1% of emitters emit over 1000 times more than the bottom 1%.^[29]

Richer (developed) countries emit more CO₂ per person than poorer (developing) countries.^[30] Emissions are roughly proportional to GDP per person, though the rate of increase diminishes with average GDP/pp of about $10,000.

The responsibility for climate change differs substantially among individuals and groups. Many of the people and nations most affected by climate change are among the least responsible for it.^[31][32] The most affluent citizens of the world are responsible for most environmental impacts. Robust action by them and their governments is necessary to reduce these impacts.^[33][34]

According to a 2020 report by Oxfam and the Stockholm Environment Institute,^[35][36] the richest 1% of the global population have caused twice as much carbon emissions as the poorest 50% over the 25 years from 1990 to 2015.^[37][38][28] This was, respectively, during that period, 15% of cumulative emissions compared to 7%.^[39] A second 2023 report found the richest 1% of humans produce more carbon emissions than poorest 66%, while the top 10% richest people account for more than half of global carbon emissions.^[40][41]

The bottom half of the population is directly responsible for less than 20% of energy footprints and consume less than the top 5% in terms of trade-corrected energy. High-income people usually have higher energy footprints as they use more energy-intensive goods. In particular, the largest disproportionality was identified to be in the domain of transport, where the top 10% consume 56% of vehicle fuel and conduct 70% of vehicle purchases.^[42]

A 2023 review article found that if there were a 2^oC temperature rise by 2100, roughly 1 billion primarily poor people would die as a result of primarily wealthy people's greenhouse gas emissions.^[43][44]

People need to make changes, including sacrifices, to enable climate justice for future generations.^[46] This could include uncomfortable lifestyle-changes,^[47][48] alterations to public spending and other individual actions on climate change.

Preventable severe effects of climate change are likely to occur during the lifetime of the present adult population. Under current climate policy pledges, children born in 2020 (e.g. "Generation Alpha") will experience over their lifetimes, 2–7 times as many heat waves, as well as more of other extreme weather events compared to people born in 1960. This raises issues of intergenerational equity as it was these generations (individuals and their collective governance and economic systems) who are mainly responsible for the burden of climate change.^[49][50]

This illustrates that emissions produced by any given generation can lock-in damage for one or more future generations. Climate change could progressively become more threatening for the generations affected than for the generation responsible for the threats. The climate system contains tipping points, such as the amount of deforestation of the Amazon that will launch the forest's irreversible decline.^[51][52] A generation whose continued emissions drive the climate system past such significant tipping points inflicts severe injustice on multiple future generations.^[53]

Disadvantaged groups will continue to be especially impacted as climate change persists.^[54] These groups will be affected due to inequalities based on demographic characteristics such as gender, race, ethnicity, age, and income.^[55] Inequality increases the exposure of disadvantaged groups to harmful effects of climate change.^[55] The damage is worsened because disadvantaged groups are last to receive emergency relief and are rarely included in the planning process at local, national and international levels for coping with the impacts of climate change.^[56]

Communities of color, women, indigenous groups, and people of low-income all face higher vulnerability to climate change.^[57][19] These groups will be disproportionately impacted by heat waves, air quality, and extreme weather events.^[58] Women are also disadvantaged and will be affected by climate change differently than men.^[59] This may impact the ability of minority groups to adapt, unless steps are taken to provide these groups with more access to universal resources.^[60] Indigenous groups are affected by the consequences of climate change even though they historically have contributed the least to causing it.^[58] Indigenous peoples are unjustifiably impacted due to their low income, and continue to have fewer resources to cope with climate change.^[61]

There are three principles of justice in burden-sharing that can be used in making decisions on who bears the larger burdens of climate change globally and domestically: a) those who most caused the problem, b) those who have the most burden-carrying ability and c) those who have benefited most from the activities that cause climate change.^[65] A 2023 study estimated that the top 21 fossil fuel companies would owe cumulative climate reparations of $5.4 trillion over the period 2025–2050.^[66]

Another method of decision-making starts from the objective of preventing climate change e.g. beyond 1.5 °C, and from there reasons backwards to who should do what.^[67] This makes use of the principles of justice in burden-sharing to maintain fairness.

By December 2022, the number of climate change-related lawsuits had grown to 2,180, more than half in the U.S. (1,522 lawsuits).^[69] Based on existing laws, some relevant parties can already be forced into action by means of courts.^[68]

Climate justice may often conflict with social stability. For example, interventions that establish more just product pricing could result in social unrest.^[80][81] Decarbonization interventions could lead to decreased material possessions, comfort, maintained habits.^{[33][additional citation(s) needed]}

Multiple studies estimate that if a rapid transition were to be implemented the number of jobs could increase overall at least temporarily due to increased demand for labor to e.g. build public infrastructure and other green jobs to build the renewable energy system.^[82][83][84]

The urgent need for changes, especially when seeking to facilitate lifestyle-changes and shifts on an industry scale, could lead to social tension and decrease levels of public support for political parties in power.^[85][86] For instance, keeping gas prices low is often "really good for the poor and the middle class".^[87]

Some may see climate justice arguments for compensation by rich countries for natural disasters in developing countries as a way for "limitless liability". High levels of compensations could drain a society's resources, efforts, focus and financial funds away from efficient preventive climate change mitigation towards e.g. immediate climate change relief compensations.^[88][89]

The US, China and Russia have cumulatively contributed the greatest amounts of CO₂ since 1850.^[90]

Many of the heaviest users of fossil fuels rely on them for a high percentage of their electricity.^[91]

Fossil fuel phase out is projected to affect states and their citizens with large or central industries of fossil-fuels extraction – including OPEC states – differently than other nations. These states have obstructed climate negotiations and it has been argued that, due to their wealth, they should not need to receive financial support from other countries but could implement adequate transitions on their own in terms of financial resources.^[92][93][94]

A study suggested governments of nations that have historically benefited from extraction should take the lead, with countries that have a high dependency on fossil fuels but low capacity for transition needing some support to follow.^[95] In particular, transitional impacts of a rapid extraction phase-out is thought to be better absorbed in diversified, wealthier economies as they may have more capacities for enacting absorptive socioeconomic policies.^[96]

Different interpretations and perspectives, arising from different interests, needs, circumstances, expectations, considerations and histories, can lead to highly varying ideas of what is fair. This may make it more difficult for countries to reach an agreement.^[98] Developing effective, legitimate and enforceable agreements could be complicated. This is especially the case if traditional methods or tools of policy-making are used.

Fundamental fairness principles could include: Responsibility, capability and rights (needs). For these principles, country characteristics can predict relative support.^{[99][additional citation(s) needed]}

The concept of climate justice was deeply influential on climate negotiations years before the term "climate justice" was regularly applied to the concept. In December 1990 the United Nations appointed an Intergovernmental Negotiating Committee (INC) to draft what became the Framework Convention on Climate Change (FCCC), adopted at the UN Conference on the Environment and Development (UNCED) in Rio de Janeiro in June 1992.^[103] As the name "Environment and Development" indicated, the fundamental goal was to coordinate action on climate change with action on sustainable development. It was impossible to draft the text of the FCCC without confronting central questions of climate justice concerning how to share the responsibilities of slowing climate change fairly between developed nations and developing nations. 

The issue of the fair terms for sharing responsibility was raised forcefully for the INC by statements about climate justice from developing countries.^[104] In response, the FCCC adopted the now-famous (and still-contentious) principles of climate justice embodied in Article 3.1:^[105] "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." The first principle of climate justice embedded in Article 3.1 is that calculations of benefits (and burdens) must include not only those for the present generation but also those for future generations. The second is that responsibilities are "common but differentiated", that is, every country has some responsibilities, but equitable responsibilities are different for different types of countries. The third is that a crucial instance of different responsibilities is that in fairness developed countries' responsibilities must be greater. How much greater continues to be debated politically.^[106][107]

In 2000, at the same time as the Sixth Conference of the Parties (COP 6), the first Climate Justice Summit took place in The Hague. This summit aimed to "affirm that climate change is a rights issue" and to "build alliances across states and borders" against climate change and in favor of sustainable development.^[108]

Subsequently, in August–September 2002, international environmental groups met in Johannesburg for the Earth Summit.^[109] At this summit, also known as Rio+10, as it took place ten years after the 1992 Earth Summit, the Bali Principles of Climate Justice^[110] were adopted.

In 2004, the Durban Group for Climate Justice was formed at an international meeting in Durban, South Africa. Here representatives from NGOs and peoples' movements discussed realistic policies for addressing climate change.^[111]

In 2007 at the 13th Conference of the Parties (COP 13) in Bali, the global coalition Climate Justice Now! was founded, and, in 2008, the Global Humanitarian Forum focused on climate justice at its inaugural meeting in Geneva.^[112]

In 2009, the Climate Justice Action Network was formed during the run-up to the Copenhagen Summit.^[113] It proposed civil disobedience and direct action during the summit, and many climate activists used the slogan 'system change not climate change'.

In April 2010, the World People's Conference on Climate Change and the Rights of Mother Earth took place in Tiquipaya, Bolivia. It was hosted by the government of Bolivia as a global gathering of civil society and governments. The conference published a "People's Agreement" calling, among other things, for greater climate justice.^[101]

In September 2013 the Climate Justice Dialogue convened by the Mary Robinson Foundation and the World Resources Institute released their Declaration on Climate Justice in an appeal to those drafting the proposed agreement to be negotiated at COP-21 in Paris in 2015.^[114]

In December 2018, the People's Demands for Climate Justice, signed by 292,000 individuals and 366 organizations, called upon government delegates at COP24 to comply with a list of six climate justice demands.^[115] One of the demands was to "Ensure developed countries honor their "Fair Shares" for largely fueling this crisis."

Some advance was achieved at the Paris climate finance summit at June 2023. The World Bank allowed to low income countries temporarily stop paying debts if they are hit by climate disaster. Most of financial help to climate vulnerable countries is coming in the form of debts, what often worsens the situation as those countries are overburdened with debts. Around 300 billion dollars was pledged as financial help in the next years, but trillions are needed to really solve the problem.^[116][117] More than 100 leading economists signed a letter calling for an extreme wealth tax as a solution (2% tax can generate around 2.5 trillion). It can serve as a loss and damage mechanism as the 1% of richest people is responsible for twice as many emissions as the poorest 50%.^[118]

Several studies that investigated the impacts of climate change on agriculture in Latin America suggest that in the poorer countries of Latin America, agriculture composes the most important economic sector and the primary form of sustenance for small farmers.^[119][120] Maize is the only grain still produced as a sustenance crop on small farms in Latin American nations.^[119] The projected decrease of this grain and other crops can threaten the welfare and the economic development of subsistence communities in Latin America.^[121][119] Food security is of particular concern to rural areas that have weak or non-existent food markets to rely on in the case food shortages.^[122] In August 2019, Honduras declared a state of emergency when a drought caused the southern part of the country to lose 72% of its corn and 75% of its beans. Food security issues are expected to worsen across Central America due to climate change. It is predicted that by 2070, corn yields in Central America may fall by 10%, beans by 29%, and rice by 14%. With Central American crop consumption dominated by corn (70%), beans (25%), and rice (6%), the expected drop in staple crop yields could have devastating consequences.^[123]

The expected impacts of climate change on subsistence farmers in Latin America and other developing regions are unjust for two reasons.^[120][124] First, subsistence farmers in developing countries, including those in Latin America are disproportionately vulnerable to climate change^[124] Second, these nations were the least responsible for causing the problem of anthropogenic induced climate.^{[124][better source needed]}

Disproportionate vulnerability to climate disasters is socially determined.^[120][124] For example, socioeconomic and policy trends affecting smallholder and subsistence farmers limit their capacity to adapt to change.^[120] A history of policies and economic dynamics has negatively impacted rural farmers.^[119] During the 1950s and through the 1980s, high inflation and appreciated real exchange rates reduced the value of agricultural exports.^[119] As a result, farmers in Latin America received lower prices for their products compared to world market prices.^[119] Following these outcomes, Latin American policies and national crop programs aimed to stimulate agricultural intensification.^[119] These national crop programs benefitted larger commercial farmers more. In the 1980s and 1990s low world market prices for cereals and livestock resulted in decreased agricultural growth and increased rural poverty.^[119]

Perceived vulnerability to climate change differs even within communities, as in the example of subsistence farmers in Calakmul, Mexico.^[125]

Adaptive planning is challenged by the difficulty of predicting local scale climate change impacts.^[120] A crucial component to adaptation should include government efforts to lessen the effects of food shortages and famines.^[126] Planning for equitable adaptation and agricultural sustainability will require the engagement of farmers in decision-making processes.^[126]

Due to climate change, tropical cyclones are expected to increase in intensity and have increased rainfall, and have larger storm surges, but there might be fewer of them globally. These changes are driven by rising sea temperatures and increased maximum water vapour content of the atmosphere as the air heats up.^[127] Hurricane Katrina in 2005 showed how climate change disasters affect different people individually,^[128] as it had a disproportionate effect on low-income and minority groups.^[128] A study on the race and class dimensions of Hurricane Katrina suggests that those most vulnerable include poor, black, brown, elderly, sick, and homeless people.^[129] Low-income and black communities had little resources and limited mobility to evacuate before the storm.^[130][131] After the hurricane, low-income communities were most affected by contamination,^[128] and this was made worse by the fact that government relief measures failed to adequately assist those most at risk.^[132][129]

In 2022, Pakistan faced catastrophic floods that affected over 33 million people and resulted in significant loss of life and property. The unprecedented monsoon rains and melting glaciers, attributed to climate change, submerged one-third of the country under water. Despite contributing less than 1% to global greenhouse gas emissions, Pakistan is disproportionately impacted by climate-induced disasters. This situation highlights the essence of climate justice, emphasizing how nations with minimal contributions to global emissions suffer the most severe consequences.^[133]
