Brazil ratifies Paris Agreement to reduce emission of CO2
Brazil has ratified its participation in the Paris Agreement on climate change.
The country's commitment is significant because it is Latin America's top emitter of greenhouse and other gases, and the seventh largest worldwide.
President Michel Temer ratified the agreement on Monday in a ceremony in the capital of Brasilia.
The Paris Agreement will enter into force once 55 countries representing at least 55% of global emissions have formally joined it.
Climate experts say that could happen later this year.
Countries set their own targets for reducing emissions. The targets are not legally binding, but nations must update them every five years.
Using 2005 levels as the baseline, Brazil committed to cutting emissions 37% by 2025 and 43% by 2030.
