我们必须要制定一项计划——温室气体污染不是凭我们的主观愿望就能消失的。为此，众多国家在气候峰会COP21即将于12月份在巴黎召开之际，相继提交了减少二氧化碳和其他有害气体排放的计划。

这些计划被称为“国家自定贡献预案”(Intended Nationally Determined Contributions)，或INDC，是对为了我们所有人都拥有一个更健康的未来而采取行动的公开承诺。这些INDC致力于解决气候变化问题，具体来说就是发电站、汽车、工厂等人为污染源释放的二氧化碳及其他污染物。

将近150个国家，占全球排放总量的85%，都已制定了目标。这代表着来自各大洲的范围广泛的发达国家和发展中国家所采取的行动。美国制定的目标是到2030年将排放量降至2005年水平的26%到28%以下。巴西承诺到2025年将排放量从2005年的水平上削减37％。它计划使用更多的可再生能源并遏制森林砍伐。印度力争到2030年将以非化石燃料为基础的发电量增至40%。

埃塞俄比亚计划到2030年将根据目前排放水平预期达到的排放量减少64%。中国的目标是到2030年达到二氧化碳排放峰值，并做出最大努力尽早达到峰值。

How will your country make it easier to breathe?

There has to be a plan — greenhouse gas pollution can’t be wished away. That’s why so many countries have been submitting plans to reduce carbon dioxide and other harmful emissions in the run-up to COP21, the climate summit to be held in Paris in December.

Called Intended Nationally Determined Contributions, or INDCs, these plans are public pledges to take steps toward a healthier future for us all. The INDCs tackle the causes of climate change, specifically the release of carbon dioxide and other pollutants from power plants, motor vehicles, factories and other man-made sources.

Nearly 150 countries, representing 85 percent of global emissions, have set targets. These pledges represent action by a broad spectrum of developed and developing countries from every inhabited continent. The U.S. set a target to cut emissions 26 to 28 percent below 2005 levels by 2030. Brazil pledges to cut its emissions 37 percent by 2025 compared to 2005 levels. Its plan is to introduce more renewable energy sources and curb deforestation. India aims to reach 40 percent non-fossil-fuel-based power generation by 2030. Ethiopia plans to reduce its emissions by 64 percent below projected business-as-usual emissions by 2030. China’s target is to achieve the peaking of carbon dioxide emissions by 2030 and make the best effort to peak early.

Find out how your country is planning to help us all breathe easier. Countries’ INDCs are posted on the INDC submissions page of the online newsroom for the U.N. Framework Convention on Climate Change.
