Efficiently offsetting (Image: Image Source/Rex Features)
CHAMPIONS of carbon offsetting may have been barking up the wrong tree. It is generally assumed that the tropics are the best place to plant forests in order to sequester carbon and cool the planet, but a study of the effects of tree planting is casting doubt on this idea. To maximise climate benefits we should be planting trees at higher latitudes, the study suggests.
Alvaro Montenegro at St Francis Xavier University in Nova Scotia, Canada, and colleagues used high-resolution satellite data to work out where new forests would bring the biggest benefit.…
