Brazil reverses Amazon deforestation through renewed enforcement under Marina Silva (2023-2024)
After returning as Brazil's environment and climate minister in January 2023, Marina Silva led a restoration of environmental enforcement, satellite monitoring and inter-agency coordination. In the causal graph this event weakens Tropical deforestation pressure, a driver that strengthens Global CO2 emissions per capita — an improving welfare path.

After returning as Brazil's environment and climate minister in January 2023, Marina Silva led a restoration of environmental enforcement, satellite monitoring and inter-agency coordination. Official PRODES data show Amazon deforestation fell 30.63% in August 2023-July 2024 and 45.7% across the two years from the 2022 level. The turnaround reversed the prior surge and supported Brazil's pledge to end illegal deforestation by 2030.
