Climate change is a common challenge to the human race. It is not only a global environmental problem, but it will also negatively affect the development of every country in the world, especially developing countries. The scientific evidence revealed by the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) in December 2007, shows that “many natural systems are being affected by regional climate changes, particularly temperature increases”. If no active actions are taken to reduce greenhouse gas emissions, climate change will adversely affect basic factors which the human beings depend on for a living, such as water resources, food, human health and the environment. And the fifth Assessment Report of IPCC has further strengthened the scientific conclusion that human activity accounts for climate change. Addressing climate change is common responsibility and requires efforts by all the countries in the world.

As a responsible developing country, China attaches great importance to climate change, is making positive efforts to reach a new global agreement in 2015, all levels has emphasized climate change, made positive progress, and increased their ability to mitigate the efforts of and adapt to climate change. The development of mechanisms, standard systems addressing climate change has been gradually improved. The people’s awareness of low-carbons increased. In 2012 CO₂ emissions per unit of GDP fell 5.02 percent compared to 2011. By the end of 2012, the output of China’s energy saving and environmental protection industry exceeded 2.7 trillion yuan. China’s current capacity in hydropower, nuclear, solar, and wind power, and plantation areas all rank first in the world, which has made a positive contribution to addressing global climate change. The 18^th Communist Party of China (CPC) National Congress, held in November 2012, set forth that in the face of increasing constraints on resources, severe environmental pollution and a deteriorating ecosystem, it is essential to raise our ecological awareness of the need to respect, follow and protect nature. These actions will increase the strategic position of combating climate change in China’s overall economic and social development. During the coming period, which is critical for China in building a moderately prosperous society in all respects, China will put more emphasis on quality, and performance of the economic growth, promote ecological progress, and make greater efforts to control greenhouse gas emissions, and make positive contributions to the global climate change issue.

As one of environmental civil society organizations (CSOs) in the field of the environment in China, All China Environment Federation (ACEF) , in order to fulfill the strategy of combating climate change in China and the world at large, from the environmental CSOs’ respective, has made active actions to make contribution to addressing climate change.

Firstly, to make policy recommendation. In October 2008,ACEF organized one sub-forum of the 7^th Asian-European People’s Forum, with the theme “Climate Change and Ecological Equity from Asian-European perspective” clarified China’s basic position of combating climate change and appealed that developed countries should provide funding and technology to developing countries according to their commitments. In September 2010, ACEF organized the sixth Forum on Environment and Development (FED 6) whose theme is addressing climate change, develop low-carbon economy and promote sustainable development”, and outputted suggestions and submitted these suggestions to relative government of China. Secondly, to build a platform of environmental CSOs. Since 2005, ACEF with other environmental CSOs jointly co-organized Annual Meeting of Environmental Civil Society Organizations on Sustainable Development and build a civil platform for environmental CSOs to make communication and cooperation, and share information and experience. At the 2010 Annual Meeting, representatives from more than 400 environmental CSOs were invited to discuss on how to cooperate with each other and share experience on combating climate change.  Thirdly, to make education and publication. ACEF carried out many activities on addressing climate change all over China and increased public awareness of climate change and low-carbon development. In 2011, ACEF and China Tourism Association jointly carried out the National Low-carbon Tourism Demonstration Place in 48 scenic regions in China. In 2012, ACEF made education and publication on electricity-saving and emission reduction at the Low-carbon Celebrity during the 2012 Scientific Technology Week organized by Beijing Hepingjie Commission. Fourthly, to make international communication and cooperation. With the support of UNDP, GEF/SGP, ACEF designed and implemented the international project named “Beijing Demonstration Programme of Household family to reduce electricity emissions in community”. Through practical implementation of energy saving and emission reduction measures to 10,000 families (3 people per family) in the demonstration community in Beijing, the project aims mainly to enhance the family energy saving and emission reduction consciousness of the Beijing residents and explore the mode of domestic consumption for family energy saving and emission reduction in big and medium sized urban communities in China. In 2013, the project was selected by UN Publication.

This year is a critical time in the international climate change negotiations. At the end of last year, the Doha Climate Change Conference concluded the negotiations on the authorization of Bali Road Map and this year’s Warsaw Climate Change Conference should be an implementation and launch meeting. How to move our negotiations forward along the dual tracks spelled out in the Bali Road Map and to reach a fair and effective agreed arrangements on addressing climate change after 2015 is a matter of urgency, which will have a great bearing on the development of all the countries and the future of the human race. Based on relative study and experiences, I would like to put forward following ideas on how to work together to address climate change.  

 I. To address climate change within the framework of sustainable development. Climate change arises in the process of development, and should thus be solved along with development. Addressing climate change must be integrated with implementation of sustainable development policies and measures. The international arrangements on climate change after 2015 should not be formulated at the expense of sustainable development of developing countries. 
    II. To adhere to the principle of "common but differentiated responsibilities". In the context of climate change, "common responsibilities" mean that both developed and developing countries have the responsibilities to address climate change; “Differentiated responsibilities” mean that because of the difference in their accumulated emissions in history, per-capita emission, level of development, and national conditions and capabilities, developed and developing countries have  different responsibilities and obligations, and should take different ways to combat climate change. Only by upholding the principle of "Common but differentiated responsibilities", can it be possible for every country to fully and fairly take their responsibilities and obligations. We oppose to any attempt in deviating from the common understanding reached at UN Conference on Environment and Development and re-define the principle of "common but differentiated responsibilities".     
    III. To place equal importance on both mitigation and adaptation. In terms of mitigation, developed countries should take the lead in reducing their GHG emissions, strictly meet their emission reduction targets set in the Kyoto Protocol for the first commitment period, and cut their greenhouse gas emissions by at least 25-40% below 1990 level by 2020 as a medium-term target. The developed countries who have taken commitments under the 2nd commitment period of the Kyoto Protocol will raise their ambition level in 2014 in consonance with science and their historical responsibility. The developed countries which are not part of Kyoto Protocol or have not joined the 2nd commitment period must equally raise their ambition in the same time frame and take on comparable mitigation commitments under the Convention. Meanwhile, developing countries will also take appropriate and effective mitigation measures in accordance with their national conditions in the context of sustainable development and with the support of developed countries.
