The world is already facing the consequences from climate change. If we are to avoid much more dangerous and costly impacts, current levels of greenhouse gas emissions must be slashed in half by 2030 and reach net-zero by mid-century.
The largest emissions sources, like the energy sector, are good places to start. But to fully tackle the climate crisis, we will need deep reductions across all sectors, big and small. Switching to renewable energy, electrifying the transportation sector, introducing more sustainable agriculture practices, curbing deforestation and forest degradation, and producing less waste are a few key ways to drive greenhouse gas emissions downward and set the world on course for a safer future.
