The Intended Nationally Determined Contributions (INDCs) are the emissions reduction targets voluntarily set by each individual signatory country to the United Nations Framework Convention on Climate Change. They constitute a part of the agreement reached at the United Nations Climate Change Conference (COP21) held in Paris in late 2015.
On June 30, 2015, China submitted to the United Nations a plan of action entitled Enhanced Actions on Climate Change: China's Intended Nationally Determined Contributions. Based on its prevailing national conditions, the stage of development at which it stands, a strategy for sustainable development, and the international responsibilities that it bears, China has made a set of commitments that are to be reached by 2030 at the latest: to achieve its peak carbon dioxide emissions (and to make every possible effort to peak earlier); to lower carbon dioxide emissions per unit of GDP by 60 to 65 percent from the 2005 level; to increase the share of non-fossil fuels in primary energy consumption to around 20 percent; to increase its forest stock by around 4.5 billion cubic meters against the 2005 level.
China also unveiled its future goals through 2020, 2030, and thereafter, and outlined the relevant policies and measures designed to attain these goals. China's INDCs herald a new policy, and represent a pledge it has made to the international community.
"國家自主貢獻"是《聯合國氣候變化框架公約》各締約方根據自身情況確定的應對氣候變化行動目標，是2015年底在巴黎召開的第21屆聯合國氣候變化會議協議的組成部分。
中國政府於2015年6月30日向聯合國提交了《強化應對氣候變化行動——中國國家自主貢獻》。在這個報告裡，中國政府根據自身國情、發展階段、可持續發展戰略和國際責任，確定了到2030年的自主行動目標，即：二氧化碳排放2030年左右達到峰值並爭取儘早達峰；單位國內生產總值二氧化碳排放比2005年下降60%-65%，非化石能源佔一次能源消費比重達到20%左右，森林蓄積量比2005年增加45億立方米左右。
中國還明確提出從當前到2020年、2030年及以後的行動路線圖，為落實"貢獻"目標規劃了詳細的政策措施和實施路徑。中國此次提出的"國家自主貢獻"，是向國際社會作出的新的政策宣示和行動承諾。
