The State of Colorado's recently-enacted Clean Air-Clean Jobs Act (CACJA) requires utilities to create plans that reduce NOx emissions by 70% at a specified portion of their coal-fired electricity generation facilities by the end of 2017. It allows utilities to use many different methods to achieve those reductions, but encourages and incentivizes the replacement of coal-based generation with natural gas. Utilities must seek approval for their plans from state agencies and must work closely with those agencies in designing the plans. This paper discusses the legal, political, and economic context for CACJA, and highlights the bill's advantages and disadvantages as a potential model for other states.
