Carbon dioxide will have to be removed from air to achieve 1.5C, says report

Offset markets have important role as switching to renewable energy alone not enough, according to thinktank

Removing carbon dioxide from the air will now be essential if there is to be any chance of meeting global climate targets, a thinktank has warned.

Carbon offset markets will need to be tidied up and managed properly, as offsets will form a critical route to limiting global heating to 1.5C in line with scientific warnings, according to the Energy Transitions Commission, as switching to renewable energy alone will not produce enough carbon savings. Other methods, such as tree planting and carbon capture and storage, will also be critical.
