In 2009, the Global Environment Institute (GEI) celebrated its fifth birthday. Five years of experience and practice have further matured GEI. In 2009, gei continued to carry out in-depth research on the "comprehensive solution to environmental problems" method proposed by itself, found problems, analyzed problems, coordinated relations, proposed measures, formulated plans, implemented projects, and finally solved problems well, making new progress and breakthroughs in mechanism, technology and policy. In view of the environmental impact of Chinese enterprises in the process of overseas investment and development, we completed the Research Report on China's environmental protection policy in foreign investment and assistance in 2009, held a seminar attended by the government departments, prepared the environmental behavior guide for Chinese overseas enterprises, and submitted it to the relevant departments of the Chinese government. Then we began to steadily promote the formulation of relevant environmental policies of local governments of developing countries and environmental compensation demonstration projects of Chinese overseas enterprises, and gradually formed a comprehensive problem-solving framework of Chinese government policies, government policies of resource host countries and Chinese enterprise demonstration. In 2009, we carried out research on climate change from various aspects and levels. In terms of policy research, two policy research reports have been completed, namely, "promoting cooperation on clean energy development between China and the United States - Research on energy conservation and renewable energy policies in Guangdong and California" and "comparative study on energy efficiency policies and practices between China and the United States"; in terms of cooperation between China and the United States, the model of "Climate Action Plan" at the state level of the United States has been introduced to organize Chinese energy-saving enterprises The industry participated in the "California climate change summit" and successfully held a side meeting at the Copenhagen Climate Change Conference on the theme of "accelerating technology diffusion - the practice of Chinese NGOs". In 2009, we successfully extended the "floating cover" biogas technology to Shaoguan, Guangdong, Shangri La, Yunnan, Hongyuan, Sichuan and other high-altitude areas. In 2009, we built 309 new biogas digesters and repaired 103 damaged biogas digesters in Baoxing County, a post disaster reconstruction area of May 12 in Sichuan Province, which is also a giant panda reserve and our project site. We helped restore the local bee and rabbit breeding projects and protected the species "Chinese bee". In 2009, we completed the sustainable development policy capacity building project for decision makers of China's high-level government. Ten teachers from the Party School of the CPC Central Committee went abroad to participate in the training and completed the compilation of "teaching materials for environment and sustainable development of the Party School of the CPC Central Committee". At the same time, we have developed and promoted the "China Pudong Cadre Management College" training and trainer program. In 2009, through the "rural entrepreneurs" and "environmental entrepreneurship" training programs, we will pave the way for the future development of environmental friendly enterprises, green employment and entrepreneurship, and low-carbon economic development in the future. 2009 is a year of steady progress for GEI. I would like to thank all the people who are interested in gei and the institutions and experts who have given gei support. In 2010, gei will continue to strengthen its research ability and strength, and continue to work hard to achieve its goals!
