Carbon removal: Cleaning up the atmosphere

The necessity of negative emission technologies (NETs)/Carbon removal seems undoubtful. Even if we concede best efforts to reduce CO2 emissions, returning to pre-industrial atmospheric CO2 levels will require a reduction of the current CO2 level in the atmosphere – and the oceans, too. Different technologies are competing, and the voluntary carbon offset market offers a …

The price tag for saving the world

The technology is there. Companies like https://carbonengineering.com/ or https://www.climeworks.com/ develop filters for sucking CO2 out of the atmosphere. With their project in Island Climeworks claims to reduce the costs of currently around 500 US$/t CO2 towards a goal of 100 US$/t. With an estimated total of around 43,1 Gt CO2 emissions per year (source: https://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth%27s_atmosphere#Anthropogenic_CO2_emissions), even a price …
