At the recent G20 summit in Rome and the climate change conference in Glasgow, some politicians in developed countries tried to shift responsibility for the future of the earth. This disregard for the responsibilities and capabilities of different countries is not only unfair and unreasonable, but also bound to undermine the common human goal of controlling global temperature rise. In fact, developed countries bear greater responsibility for the accumulated and transferred carbon emissions. First, the historical cumulative responsibility for carbon emissions cannot be shirked. Carbon dioxide can stay in the atmosphere for hundreds of years, that is, the greenhouse gases emitted a hundred years ago are still warming the world today. CNN article pointed out that China's carbon emission growth began in the 21st century, and the American and western developed countries that started the industrialization process early have already emitted carbon dioxide on the planet for nearly 200 years. According to the data of the British Energy Research Institute "carbon bulletin", since 1850, the cumulative carbon emission of the United States has been 509 billion tons, twice that of China. According to the data of Rongding consulting, a research company, in 2019, the per capita carbon emission of the United States was nearly twice that of China. The 2021 Research Report of climate transparency organization points out that this is partly the reason for lifestyle. "Americans use more cars, and the per capita flight data is also higher than that of China." Secondly, the transfer responsibility of carbon emissions can not be ignored. In recent decades, it is the carbon emissions of developing countries at the bottom of the industrial chain that have supported the comfortable lifestyle of developed countries. According to estimates by Keiichiro kimmoto, associate professor of Japan's Institute of integrated geo environmental science, among the greenhouse gases emitted by China in 2015, 580 million tons came from commodities exported to the United States, 530 million tons from commodities exported to Europe and 240 million tons from commodities exported to Japan. It can be said that many of the carbon emissions of developing countries such as China are "exported" by developed countries. To think about climate equity, we also need to pay attention to the development gap between different countries. Sonia klinsky, an associate professor at Arizona State University, pointed out that with the increase of carbon emissions, its relationship with people's necessities will gradually decrease. Therefore, rich countries can reduce emissions without reducing people's living standards, while lower income countries cannot. Recently, a cartoon described by Chinese ambassador to the United States Qin Gang vividly shows the injustice and absurdity of requiring countries at different stages of development to bear the same responsibility for climate change. In the cartoon, a ragged and thin man is collecting firewood to cook. Next to him, the owner of a large displacement luxury car points to him and says, "the carbon emissions of your cooking cause global warming". Overseas netizen Ubong Essien said: "developed countries are really funny. They stole resources and hindered development. Now they are talking about climate change everywhere. If you want us to reduce emissions as much as you do, first give us back our gold, minerals and oil!" (a cartoon described by Chinese ambassador to the United States Qin Gang when communicating with Chinese and American youth at the special event of "global action initiative 2021 - climate change" climate week) Low income countries lack funds and technology to deal with climate change. The United States and other developed countries have promised to provide $100 billion in climate funds to developing countries every year by 2020, but this commitment has not been fulfilled. Addressing climate change is a common topic of mankind, which requires all countries to shoulder "common but differentiated responsibilities". As the largest developing country in the world, China has made a major commitment of "self pressurization". From carbon peak to carbon neutralization, developed countries will generally take 40-70 years, while China sets itself only 30 years. China has always made a promise and has taken action. Some developed countries should also show their ability and determination to fulfill their commitments, rather than repeatedly jumping and throwing the pot at will. (outlook new era)
