"It's not easy being green"
-Kermit the Frog
A consensus is finally shaping up among international policy-makers. Market-based emissions trading has become the modern world's primary pollution control mechanism, forming a key part of various national and international bodies' commitment to climate change mitigation. The largest such market is the European Union's Emissions Trading System, which accounts for over 90% of the world's carbon market volume, but market trading systems are also a key part of the Kyoto protocol under the Clean Development Mechanism, and looks set to be adopted in China in the near future. Unfortunately cap-and-trade emissions systems are structurally incapable of delivering us from climate change.
