Large parts of Appalachia’s forests, once owned by coal companies, now make money for investors by storing carbon. But the results bring few jobs or sizable investments for residents.

We need to urgently reform the way forest conservation is measured and sold as a way to offset emissions.

Most of the carbon disturbed by trawls is unreactive and difficult to convert to CO₂.

Airlines are promising net-zero emissions by 2050. To get there, they’re experimenting with used cooking oil, ag waste and corn ethanol in their fuel tanks. But that alone won’t be enough.

Millions of dollars have gone into California’s forest carbon offset program – with little new carbon storage to show for it, a new study suggests.

‘Blue carbon’ habitats can store a lot of carbon – but not reliably enough to offset emissions.

More carbon dioxide in the air doesn’t necessarily mean more growth for trees, and the increasing risk of wildfires and drought has major consequences, as an interactive map shows.

Plan to cut emissions quickly, use offsets sparingly and set broader goals for improving society.

The dust has settled on COP26 and one of the summit’s few achievements looks decidedly less impressive.
