Is the U.S. Ready for National Greenhouse Gas Regulation?

 by Bob Shively, Enerdynamics President and Lead Instructor

Flash back eight years ago to 2005.  U.S. greenhouse gas emissions (GHG) from energy consumption were increasing annually with emissions having grown by almost 20% since GHG1990. The Bush Administration announced in 2001 that the U.S. would not implement the Kyoto Protocol. Rather than pursuing regulatory mandates, the Administration announced support for voluntary measures and tax credits to encourage businesses to reduce GHG emissions[1].

Meanwhile in Europe, the European Union launched the European Union Emissions Trading Scheme (EU ETS), which regulated GHG emissions in 31 European countries through a cap-and-trade mechanism. Its goal was to reduce emissions by 21% by 2020.  And although emissions in China had grown significantly in recent years, China’s energy-related emissions were still almost 10% less than those in the U.S[2].

How different the world of GHG looks today.  By the end of 2011, the U.S. has reduced energy related GHG emissions by 8% since 2005. With the ongoing implementation of the EU ETS, the European Union had reduced GHG by 10%.  And China, with its rapidly expanding economy, had increased emissions by a whopping 59%.

As discussed in Enerdynamics’ recent Energy Insider[3], key factors contributing to the reduction in the U.S. include the economic downturn in 2008, growth of renewable generation, energy efficiency efforts, and perhaps most importantly a major shift from coal to natural gas-generated electricity.

Interestingly, as U.S. GHG emissions have declined in recent years, there is revived talk that the time may have come for national regulation of GHG emissions. Certainly we’ve been here before.  Legislative action has stalled numerous times, included the demise of the Waxman-Markey bill in the U.S. Senate in 2010 (despite having already passed the House and having the support of President Obama)[4].  But the U.S. Supreme Court in 2007 ruled that greenhouse gases fit within the definition of air pollution in the Clean Air Act, thus requiring the EPA to regulate GHG if the EPA determined that the gases endangered public health.  Subsequently the EPA ruled that GHG do endanger public health, and this determination was upheld by the U.S. D.C. District Court of Appeals in 2012.

The EPA has already issued proposed rules for new power plants[5], and many believe that the next logical step would be to extend rules to existing units.  The Wall Street Journal recently reported that the Edison Electric Institute, a utility trade group, may take a cooperative role in working to create national GHG regulations[6] based on a belief that legislative solutions could be more flexible than EPA rules.  And George Shultz and Gary Becker of the conservative Hoover Institution recently wrote a paper suggesting the time has come for a national revenue neutral carbon tax[7].

So does this mean that fear of EPA regulation will coalesce enough parties to get legislation passed?  In today’s fractured Washington politics, that is hard to predict.  But it is a renewed possibility.
