The survey highlights the main obstacles to achieving climate goals: lack of political will among government leaders (42% globally and 47% in Brazil), weak enforcement against deforestation and pollution (34% globally and 44% in Brazil) and lack of funding for environmental projects (31% globally and 29% in Brazil).
Despite this, 55% consider that COP30 is an opportunity for Brazil to demonstrate leadership in sustainability, and 56% advocate that indigenous peoples and traditional communities play a leading role in climate decisions.
