Mostly, we need to halt the emissions of greenhouse gases — which stem from the world’s energy use, land use and agriculture, and exotic materials — as soon as possible. There are already many opportunities to cut emissions from electricity, food and agriculture, industry, transportation, and buildings.

There are also opportunities to support and enhance natural carbon sinks that can help remove greenhouse gases we have already emitted. And there are ways to improve society that have additional climate benefits.

At Project Drawdown, we outline dozens of opportunities to reduce emissions, support carbon sinks, and improve society — keeping the world from heading towards uncontrolled climate change.
