In 2009, at the United Nations Climate Change Summit held in Copenhagen, China put forward specific measures to deal with climate change in the future: First, strengthen energy conservation, improve energy efficiency, and strive for a significant reduction in carbon dioxide emissions per unit of GDP in 2020 compared with 2005; Second, vigorously develop renewable energy and nuclear energy, and strive for non-fossil energy to account for about 15% of primary energy consumption in 2020; Third, vigorously increase forest carbon sinks, strive to increase forest area by 40 million hectares in 2020 compared with 2005, and increase forest stock by 65.438+0.3 billion cubic meters compared with 2005; Fourth, vigorously develop green economy, actively develop low-carbon economy and circular economy, and develop and popularize climate-friendly technologies.
China government has always believed that energy conservation and emission reduction are the needs of the world and China's own development. Therefore, from the perspective of being responsible to human beings and citizens, China promises not to repeat the "high carbon" development path of developed countries with high energy consumption, high emissions and high pollution, and to overcome various difficulties and actively seek ways to reduce carbon emissions and develop a low carbon economy.
In the process of accelerating industrialization and urbanization, the emissions of developing countries have also increased rapidly. In Copenhagen, the contest of responsibility sharing is mainly reflected in the discussion of long-term emission reduction responsibility. According to the IPCC report, in order to save the climate, global carbon dioxide emissions will be reduced by more than 50% by 2050. There is no doubt that this is a warning issued by climate science to all countries in the world. But for different countries, the meaning is very different.
From China's point of view, the long-term goal is very important, but the medium-term goal is even more crucial. During the Copenhagen meeting, Xie Zhenhua, head of the China delegation and deputy director of the National Development and Reform Commission, said that China can accept the goal of halving global carbon emissions by 2050, provided that developed countries promise to reduce emissions by 40% by 2020 and agree to provide financial assistance to developing countries.
