Sept. 22, 2009, Chinese President Hu Jintao called for international joint work and pledged China's continued efforts on this issue at his address at the UN Climate Change Summit. The Chinese president outlined four principles needed for a successful concerted effort to deal with climate change worldwide. Hu said that fulfilling respective responsibilities, achieving mutual benefit and a win-win outcome, promoting common development and ensuring financing and technology were of utmost importance in making these efforts work.

Meanwhile, Hu also announced four measures that China will adopt to further integrate actions on climate change into its economic and social development plan.

First, China will intensify efforts to conserve energy and improve energy efficiency, and endeavor to cut carbon dioxide emissions per unit of gross domestic product (GDP) by a notable margin by 2020 from the 2005 level, Hu said.

 "Second, we will vigorously develop renewable energy and nuclear energy. We will endeavor to increase the share of non-fossil fuels in primary energy consumption to around 15 percent by 2020," he added.

 Third, China will energetically increase forest carbon sink and endeavor to increase forest coverage by 40 million hectares and forest stock volume by 1.3 billion cubic meters by 2020 from the 2005 levels, Hu said.

"Fourth, we will step up effort to develop green economy, low-carbon economy and circular economy, and enhance research, development and dissemination of climate-friendly technologies." he added.
