A fossil fuel phase-out is a plan to stop using fossil fuels. Fossil fuels are fuels that are made from plants and animals that died millions of years ago. They include things like oil, coal, and gas. We use fossil fuels to power cars, heat homes, and run factories.
When we use fossil fuels, they release harmful gases into the air, like carbon dioxide and methane. This causes global warming and air pollution, which can make people sick and hurt the environment. So, a fossil fuel phase-out is a plan to stop using fossil fuels and start using cleaner forms of energy, like wind and solar power. With a fossil fuel phase-out, we can reduce air pollution, slow down global warming, and create a healthier environment for everyone.
