Why geoengineering is a public good, even if it is bad
- 1.8k Downloads
Stephen Gardiner argues that geoengineering does not meet the “canonical technical definition” of a global public good, and that it is misleading to frame geoengineering as a public good. A public good is something that is nonrival and nonexcludable. Contrary to Gardiner’s claims, geoengineering meets both of these criteria. Framing geoengineering as a public good is useful because it allows commentators to draw on the existing economic, philosophical, and social scientific literature on the governance of public goods.
