Where does CO₂ come from?
75% of global emissions come from energy. Not deforestation.
Fonte: IPCC AR5 (2014) — medianas de ciclo de vida. Nuclear emite ~68× menos CO₂ que carvão.
75% of all greenhouse gas emissions in the world come from energy generation. Not from deforestation. Not from agriculture. From energy.

The global energy mix is still dominated by fossil fuels:
- Oil: 30.2%
- Coal: 27.6%
- Natural gas: 23.1%

These three fuels generate around 21.3 billion tonnes of CO₂ per year — the leading cause of global warming.
Renewable energies have minimal environmental impact, but one critical limitation: they depend on nature. There is no sun at night. There is no wind every day. Without industrial-scale storage, they cannot be the sole backbone of the energy mix.
This is where nuclear energy comes in: clean, continuous, and weather-independent.
