CLIMATE - Carbon dioxide removal can lower costs of climate protection

Directly removing carbon dioxide from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the financial burden on future generations, a new study shows.
