The 26th United Nations Climate Change Conference of the Parties (COP26) was held in Glasgow, United Kingdom, on November 1st. Most countries proposed the amount of carbon emission goals and set a target of Net-zero. According to the Paris Climate Change Accord, countries all around the world should achieve Net-zero by 2050. To prevent global warming, the 1st and 2nd countries responsible for the worst greenhouse gas emissions, China and the United States (U.S.), and the 3rd and 4th countries, India and Russia, should join in trying to reach this target. However, since China and the U.S. have blamed each other and could not reach an agreement, there had been difficulties in getting agreement from those countries. Even though the U.S. proposed the Net-zero by 2050, China and Russia suggested 2060. Even India set the deadline as 2070, and there had been some differences in opinions among countries. For this situation, the President of the U.S., Joe Biden, showed disappointment toward China’s uncooperative attitude. On the other hand, Xi Jinping, the Leader of China, criticized that the amount of carbon emissions per person is much greater in the U.S. saying that the success of COP26 is based on a decision of the U.S. Moreover, the Prime Minister of India emphasized that developed countries should try hard to achieve Net-zero. As a result, the members made a small but final agreement of reducing the amount of carbon emissions by more than 30% until 2030 compared to the amount of 2020.
