Now, President Carlos Alvarado Quesada aims to turn Costa Rica into a global example in tackling climate change.
Proportionally, the country's contribution to global warming is negligible: only 0.02% of global carbon emissions come from Costa Rica. Meanwhile, the world's 10 most polluting nations account for almost 70% of the world's greenhouse gas production . . .
