If land use-related emissions are included, however, the picture changes dramatically, giving it 5% of global emissions and making Brazil the fourth-largest emitter after China, the United States and the EU. The per capita figure increases to 12 tonnes per year.44 This reflects the fact that agriculture and forestry play a major role in the Brazilian economy, with deforestation responsible for over half the country's current greenhouse gas emissions, and the fact that biofuels constitute a substantial part of its energy mix. According to McKinsey45 the opportunities from land use put Brazil among the five countries with the greatest potential to reduce emissions by 2030 - and at a comparatively low cost. Nonetheless, the Brazilian economy is projected to grow considerably, and the possibility of increased emission intensities raises questions about the future trajectory of Brazilian emissions.
