Brazil's environmental goals suffered a major setback in May as deforestation in the Amazon surged 92% compared to the same month last year, according to official monitoring data released Friday.

Brazil is one of the world’s top 10 emitters of greenhouse gases, contributing about 3% of global emissions, according to the nonprofit Climate Watch. Almost half of those emissions come from deforestation, making efforts to halt it critical to meeting Brazil’s commitments under the 2015 Paris Agreement.
