Since fossil fuels are the largest single source of carbon emissions, the quantity that can be produced is limited by the Paris Agreement of 2015 to keep global warming below 1.5 °C.

- Energy transition

Recognition of the climate crisis, pollution and other negative impacts caused by fossil fuels has led to a widespread policy transition and activist movement focused on ending their use in favor of sustainable energy.

- Fossil fuel

fossil-fuel power plants and biomass power plants both have smoke stacks (see for example environmental impact of the coal industry)

- Air pollution

Additionally, the replacement of coal-based energy with renewables can lower the number of premature deaths caused by air pollution and reduce health costs.

- Energy transition

Pollution prevention seeks to prevent pollution such as air pollution and could include adjustments to industrial and business activities such as designing sustainable manufacturing processes (and the products' designs) and related legal regulations as well as efforts towards renewable energy transitions.

Coal, oil, and natural gas remain the primary global energy sources even as renewables have begun rapidly increasing.

Renewable energy stands in contrast to fossil fuels, which are being used far more quickly than they are being replenished.

It would also reduce environmental pollution such as air pollution caused by the burning of fossil fuels, and improve public health, reduce premature mortalities due to pollution and save associated health costs that could amount to trillions of dollars annually.

The transition to renewable energy depends on non-renewable resources, such as mined metals.
