Why is Brazil unique when it comes to climate change? Brazil is a major emerging economy and it is the sixth-largest emitter of greenhouse gases. However, its fossil fuel-based emissions are low by global standards. Brazil has been innovative in developing some relevant low carbon ways of generating energy and pioneered significant transport innovations. It has also played a major role in international debates on global warming and Brazilians’ degree of concern about global warming is higher than almost anywhere else. Brazil has the largest reserve of agricultural land in the world and it houses most of the Amazon forest and river basin.
