Forests take in carbon from the air and store it in wood, plant matter, and under the soil. Restoring them is an important option for combating climate change.

Wildfires are becoming more frequent and severe as a result of climate change, as forests in arid parts of the world become hotter and drier.

Aviation emissions are responsible for around 5% of climate warming, and this share is rising.

Hydrogen is the most abundant chemical substance in the universe. It can be used as a fuel that does not produce greenhouse gases when burned.

Biofuel is any liquid fuel made from “biomass”—plants and other biological matter like animal waste and leftover cooking fat.
