Because this week’s focus on greenhouse gases (GHG) is related to my personal project (http://v515brian.blogspot.com/2011/09/personal-project.html), I thought that I would use this opportunity to blog about my findings regarding the evolution of market-based GHG regulations in the U.S.
Prior to 1970, the federal government conducted research on air pollution but had no formal authority to issue regulations prohibiting GHG emissions. The Clean Air Act of 1970 changed this by authorizing the development of National Ambient Air Quality Standards (NAAQS) for air pollutants. The act provided a crucial incentive for compliance by allowing citizens the right to take legal action against any organization that violated the new standards. The Environmental Protection Agency (EPA) was established in 1971 in order to implement the requirements included in the Clean Air Act (http://epa.gov/oar/caa/caa_history.html).
After a long period of limited amendment, the Clean Air Act was significantly revamped in 1990 due to growing environmental concerns. Two of the driving forces behind the 1990 amendments were the desires to eliminate both acid rain and ground-level ozone which were being generated by high emission levels of Sulphur Dioxide (SO2) and Nitrogen Oxide (NOx). Amendments within the 1990 act were the first attempt by Congress to control pollution through market forces. Under the program, emissions of SO2 land NOx were capped far below 1990 emission levels. Regional organizations were established under the act in order to achieve mutual emission reduction goals (http://www.nrel.gov/docs/fy01osti/29448.pdf).
Several trading platforms have since gained traction in order to reach these emissions targets. The Northeast States for Coordinated Air Use Management, an association of northeast and mid-Atlantic states, has initiated a trading program for NOx (http://www.otcair.org/). From 2003 to 2010, the Chicago Climate Exchange (CCX) operated a Carbon Exchange. This exchange has since been dissolved and is operated as an over-the-counter (OTC) market. Most recently, the California government, in conjunction with the government of British Columbia, is working to establish a carbon market that would go into effect on January 1, 2012. In the beginning, British Columbia is expected to be a net seller of carbon credits, while California will be a net buyer.
