China’s Vice Premier, Li Keqiang, said today that the international community needs to work together to overcome the challenges of climate change, working within the United Nations Framework Convention on Climate Change (UNFCCC/Copenhagen) and Kyoto Protocol while respecting the principle of “common but differentiated responsibilities.” Li was referring to China having signed on earlier this year to the Copenhagen Accord, which essentially calls for limiting the rise in global temperatures to no more than 2 degrees Celsius beyond pre-industrial levels. China has said it plans to reduce emissions of carbon dioxide per unit of economic growth, or “carbon intensity,” by 40 to 45 percent by 2020, compared with 2005 levels. India also signed on to the Accord and set an intensity reduction target of 20 to 25 percent by 2020, compared with 2005 levels, excluding its agricultural sector. The United States has pledged to reduce greenhouse gas emissions by about 17 percent by 2020 (a target that is not tied to economic growth or carbon intensity) from 2005 levels. Li made his remarks in conjunction with briefing UNFCCC Executive Secretary Christiana Figueres in Beijing on the country’s present policies and measures to reduce energy consumption, develop green jobs and promote environmental protection. China will host a session of the follow-up U.N. climate change talks in Tianjin this October. Currently, China’s energy consumption is growing faster than any other country’s, but on a per-person basis, China still consumes far less energy than other leading economies such as the U.S. To produce more clean energy and mitigate climate impact, China, already the world’s largest manufacturer of solar panels, aims to produce 20,000 megawatts of solar energy by 2020. Together with wind power and biomass, renewable energy in China is expected to contribute about eight percent, or double the current level, of electricity generation in less than a decade. However, improvements have come with substantial costs. Upgrading the country’s electricity grid alone cost China last year about $45 billion.
