Greenhouse gas remediation projects are a type of geoengineering
and seek to remove greenhouse gases from the atmosphere, and thus

The discipline overlaps with carbon capture and storage and carbon
sequestration, and some projects listed may not be considered to be
geoengineering by all commentators, instead being described as
mitigation
