One of the state’s most powerful new climate tools could have ripple effects that go far beyond its borders.

Since 2007, Romania has lost between half and two-thirds of its virgin forest. The environmentalists and activists trying to protect it keep getting killed.

Nigeria’s forests are being decimated to make charcoal for cookouts in Europe and the United States.

Chocolate is one of the worst foods you can buy, in terms of the industry’s greenhouse gas emissions. But some people are trying to change that.

Aggressive reforestation will be required to stem climate change—and that includes the United States.

There's a wide gulf between the public pavilion and negotiations next door.
