The Brazilian state hosting a United Nations climate summit this year has denied any connection between a new road cutting through a protected area of Brazilian rainforest and the COP30 summit that will gather world leaders in November.

A new four-lane highway cutting through tens of thousands of acres of protected Amazon rainforest is being built for the COP30 climate summit in the Brazilian city of Belém. It aims to ease traffic to the city, which will host more than 50,000 people - including world leaders - at the conference in November.

The climate conference doesn't begin until November but controversy is already swirling, according to the BBC.
