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.
