How Idealism, Expressed in Concrete Steps, Can Fight Climate Change

(new-york-times, 29 Mar 2015) Idealism combined with an intriguing application of economic theory may accomplish what international conferences have not: solving the seemingly intractable problem of global warming.

Despite periodic flurries of optimism, diplomacy has been largely disappointing. The 1997 Kyoto Protocol , for example, in which many nations agreed to impose strict taxes on carbon emissions, hasn’t accomplished much. And subsequent climate conferences haven’t come up with an effective solution. Secretary of State John Kerry summed up the diplomatic landscape in December at the United Nations climate change conference in Lima, Peru: “ We’re still on a course leading to tragedy .”

From an economic standpoint, international efforts until now have foundered on a fundamental “free rider problem.” In a nutshell, individuals and nations that bear the immediate costs of measures to protect the atmosphere will experience only a small fraction of the benefits, which are shared by all the people and nations on the planet. Why not just take a “free ride” and let others do the hard work?
