Climate change has been considered the paramount global environmental problem throughout the history of human development and also the biggest externalities. The Intergovernmental Panel on Climate Change (IPCC) reports indicate that a substantial low-carbon transformation of the global economy and energy systems must be realized and that a net zero greenhouse gas emission must be achieved in the second half of the current century. The goal of these initiatives is to attain the goal of temperature rise not exceeding 2° at the end of this century. Accordingly,the world is facing unprecedented technological innovation and collaborative demands to deal with climate change. In the 2015 Paris Agreement,a long-term vision of technology development and transfer implementation was proposed,and policy and financial support for technological innovation in the area of climate change was advocated. These proposals aim to enable developing countries to acquire the necessary technology in the early stage of the technology cycle to address the global effects of climate change. However,the traditional technological innovation and cooperation mode based on industrial civilization can hardly meet the technical demands of global climate protection. Mitigation and adaptation technology is the common instrument of global communities to address the challenge of climate change. To ensure the continuous development of technology,a pursuit of private maximum interest must be abandoned and a new global technical cooperation system should be developed based on the philosophy of ecological civilization to deal with climate change. The core contents of this system are as follows:to implement all-win cooperation targets,follow cooperation principles of Eco-man,adopt cooperation content that reflects synergy, pursue cooperation based on mutual trust,encourage participation of multiple actors,and pursue cooperation and accomplishment sharing. As an emerging developing country,China has special interest for international technological cooperation to address the effects of climate change. The following measures are necessary to implement the Paris Agreement effectively:As an opportunity to speed up the international cooperation,actively implement China's general strategies and take concrete actions to deal with climate change; improve China's capability in foreign technological cooperation; pursue international and domestic cooperation in basic measurement, data statistics,and other areas related to climate change technology; actively promote China's cooperation with developed countries, other developing countries,and less developed countries regarding climate change technology; and explore the'South-North-South' tripartite technical cooperation programs and other new forms of cooperation.
