In “Who Owns the Sky? Our Common Assets and the Future of Capitalism,” entrepreneur Peter Barnes redefines the debate about climate change. By treating the sky as a commonly owned asset, he argues, we can protect the atmosphere while paying cash to every American. Barnes proposes a non-governmental Sky Trust that would charge rent for carbon emissions and pay equal yearly dividends to each one of us. The Sky Trust would also ease the burden on workers, firms and households for whom the transition to a lower-carbon economy is most difficult.
