Defossilize the Earth

The science is unambiguous: burning fossil fuels is the primary driver of climate change, and the window to prevent its worst consequences is closing. Defossilize tracks the global campaign to transition away from coal, oil, and natural gas — with data on what is working, what is not, and what comes next.

The Scale of the Problem

Fossil fuels currently supply approximately 80% of the world's primary energy. The combustion of coal, oil, and natural gas releases over 36 billion tons of CO₂ into the atmosphere annually — a figure that has increased in most years despite decades of climate commitments.

Emissions by Sector

Solutions Scaling Now

Renewable Energy

Solar and wind are now the cheapest sources of new electricity in most of the world. Global renewable capacity additions are breaking records every year.

Electrification

Replacing fossil fuel combustion with electricity from clean sources across transportation, heating, and industrial processes.

Clean Hydrogen

Green hydrogen produced from renewable electricity via electrolysis can decarbonize sectors that are difficult to electrify directly — shipping fuel, long-haul aviation, steel production, and seasonal energy storage.
