Countries are due to announce new commitments to reduce deforestation at the UN Climate Summit on Tuesday.

That’s according to the Executive Secretary of the Convention on Biological Diversity (CBD), a global agreement covering all aspects of biodiversity or the variety of life on Earth.

Thirteen million hectares of forests continue to be lost each year, the UN says.

The loss of tress means that less of the harmful carbon dioxide or CO2 emissions can be removed from the environment.

Countries that are a Party to the Convention have pledged to reduce deforestation by half by 2020 under what is called the Aichi Targets.

On the margins of the Summit, Braulio Ferreira de Souza Dias began by explaining to Jocelyne Sambira, the link between climate and biodiversity.
