Who Has The Most Historical Responsibility for Climate Change?
One of the biggest fights at the United Nations climate summit in Glasgow is whether and how the worlds wealthiest nations, which are disproportionately responsible for global warming to date, for the damages caused by rising temperatures. are responsible for half of all historical CO emissions. are responsible for the other half.

Rich countries, including the United States, Canada, Japan and much of western Europe, account for just 12 percent of the global population today but are responsible for 50 percent of all the planet-warming greenhouse gases released from fossil fuels and industry over the past 170 years.

Poorer, vulnerable countries have asked richer nations to provide more money to help adapt to these hazards. At the summit, Sonam P. Wangdi, who chairs a bloc of 47 nations known as the Least Developed Countries, pointed out that his home country of Bhutan bears little responsibility for global warming, since the nation currently absorbs more carbon dioxide from its vast forests than is emitted from its cars and homes. Nonetheless, Bhutan faces severe risks from rising temperatures, with melting glaciers in the Himalayas already creating flash floods and mudslides . We have contributed the least to this problem yet we suffer disproportionately, Mr. Wangdi said. There must be increasing support for adapting to impacts. A decade ago, the worlds wealthiest economies pledged to mobilize $100 billion per year in climate finance for poorer countries by 2020. But they are still , and very little aid so far has gone toward measures to help poorer countries cope with the hazards of a hotter planet, such as sea walls or early warning systems for floods and droughts. Separately, vulnerable countries have also emphasized that they wont be able to adapt to every storm or every hurricane or famine worsened by climate change. The world will continue to warm. People will continue to die from climate related disasters. Villages will continue to disappear beneath rising seas. So, those countries, many of which still produce a tiny fraction of overall emissions, have asked for a separate fund, paid for by wealthy countries, to compensate them for the damages they cant prevent. This issue is referred to as Lots of people are losing their lives, they are losing their future, and someone has to be responsible, said A.K. Abdul Momen, the foreign minister of Bangladesh. He compared loss and damage to the way the United States government in the 1990s to recover billions of dollars in higher health care costs from the smoking epidemic. Wealthy countries have historically resisted calls for a specific funding mechanism for loss and damage, fearing that it could open the door to a flood of liability claims. Only the government of Scotland has been willing to offer specific dollar amounts, for victims of climate disasters. At the same time, some of the worlds biggest developing economies are beginning to catch up on emissions. China, home to 18 percent of the worlds population, is responsible for nearly 14 percent of all the planet-warming greenhouse gases released from fossil fuels and industry since 1850. But today it is the worlds largest emitter by far, accounting for roughly from energy and industry this year. 30 Gt CO Rest of world India 170 Years of CO emissions 20 Developed countries China Other countries Russia Other developed 10 European Union and United Kingdom United States 1850 1900 1950 2000 2020 30 Gt CO Rest of world India 170 Years of CO emissions 20 Developed countries Other countries China Russia Other developed 10 European Union and United Kingdom United States 1850 1900 1950 2000 2020 30 Gt CO 170 Years of CO emissions Developed countries Other countries India Rest of world 20 China Russia 10 Other dev. E.U. and U.K. United States 1850 2020 China has endorsed vulnerable nations call for loss and damage financing at the climate summit in Glasgow, but so far China has not been pressured to contribute to such a fund. (So far, finance discussions at global climate talks have focused on the responsibility of developed countries, which the U.N. calls Annex II nations.) Historical responsibility isnt the only way to look at issues of justice and fairness. Another key metric is emissions per person. So, for instance, India as a whole produced about 7 percent of the worlds carbon dioxide emissions this year, roughly the same as the European Union and about half of the United States. But India has far more people than both regions combined, and is much poorer, with hundreds of millions of people lacking reliable access to electricity. As a result, its emissions per person are far lower today: Total CO emissions in 2020 Per capita 10.7 GtCO 7.4 t CO China 4.7 14.2 USA India 2.4 1.8 10.8 Russia 1.6 8.1 Japan 1.0 8.9 Iran 0.7 7.7 Germany 0.6 18.0 Saudi Arabia 0.6 11.7 South Korea 0.6 Indonesia 0.6 2.2 14.2 Canada 0.5 Brazil 0.5 2.2 7.6 South Africa 0.5 4.7 Turkey 0.4 15.4 Australia 0.4 Total CO emissions in 2020 Per capita 10.7 Gt CO 7.4 t CO China 4.7 14.2 USA India 2.4 1.8 10.8 Russia 1.6 8.1 Japan 1.0 8.9 Iran 0.7 7.7 Germany 0.6 18.0 Saudi Arabia 0.6 11.7 South Korea 0.6 Indonesia 0.6 2.2 14.2 Canada 0.5 Brazil 0.5 2.2 7.6 South Africa 0.5 4.7 Turkey 0.4 15.4 Australia 0.4 At the climate summit, the United States and the European Union have argued that the world will never be able to minimize the damage from global warming unless swiftly industrializing nations like India do more to slash their emissions. But India, which recently announced a pledge , says it needs much more financial help to shift from coal to cleaner energy, citing both its lower per capita emissions and smaller share of historical emissions. How these disputes over money get resolved is a major step in determining whether negotiators from nearly 200 countries can strike a new global deal in Glasgow to limit the risks of future global warming. An earlier version of this article misstated the amount by which Earth has heated over the past 170 years in Fahrenheit. It has warmed by roughly 1.1 degrees Celsius, which corresponds to 2 degrees Fahrenheit, not 2.7 degrees.
