What is Brazil's pathway to limit global warming to 1.5°C?
Transport
Decarbonising the transport sector
Transport emissions made up 14% of Brazil’s total emissions in 2023.1 Three quarters of transport energy consumption came from oil, while biofuels accounted for almost one quarter – amounting to a much higher biofuels share than in most other countries.2 In all 1.5°C compatible pathways analysed here, oil is phased down significantly, with growth in electricity and biofuels making up the shortfall.

Fuel shares refer only to energy demand of the sector. Deployment of synthetic fuels is not represented in these pathways.

In the Deep Electrification pathway, the share of biofuels in the transport energy mix is limited around 30%, focusing more on ramping up the transport sector’s electrification rate, with electricity reaching 64% of the sector’s energy mix by 2050, avoiding increased reliance on biofuels through higher electrification rates, adding to the overall system efficiency.
Brazil has developed a policy framework to support high levels of biofuel use, primarily ethanol and biodiesel.3 Around 85% of light duty vehicles in Brazil are flex-fuel, meaning they can run on any mix of ethanol and petrol. These fuels primarily rely on biofuels from sugarcane and soybeans, with the production of both driving deforestation.4,5
