Making Carbon Markets Work

Authors: David G. Victor and Danny Cullenward
Scientific American

The odds are high that humans will warm Earth’s climate to worrisome levels during the coming century. Policy makers in the United States, which historically has produced more CO2 emissions than any other nation while doing relatively little to tame the flow, can in particular learn much about creating viable carbon-cutting markets by studying Europe’s recent experience. In this Scientific American article, David Victor and Danny Cullenward offer several concrete suggestions on how the U.S. should go about constructing an effective national climate policy.

These include policies to combat or adapt to climate change.
