U.S. historians regard the states as "laboratories of democracy." In much the same way, states and localities can be regarded as laboratories of greenhouse gas (GHG) mitigation. States, localities, and private sector groups have implemented many innovative technologies, programs, and policies, and have demonstrated the feasibility and cost-effectiveness of a variety of methods to reduce GHGs.
Each case study features a description of the project and, where available, quantitative results in terms of GHG reductions, energy savings, and costs. It also identifies the main actors involved in managing and implementing the project, and provides contacts for obtaining additional information.
The case studies listed below illustrate the wealth of experience states, localities, and private sector groups are accumulating as they implement policies that reduce GHGs, and represent a cross-section of the broad range of approaches that can be used.
The case studies are based on available information as of October 2000. To provide updated information, correct errors, or suggest ideas for additional case studies, please use the "Contact Us" link available at the bottom of this page. The CREST and DSIRE web sites also provide extremely useful information on specific state actions:
- The CREST
(Center for Renewable Energy and Sustainable Technology) web site documents state and local government activities that have resulted in reducing or preventing greenhouse gas emissions through energy efficiency and/or renewable energy technologies, better municipal planning, and progressive sustainable energy and resource practices.
- The DSIRE (Database of State Incentives for Renewable Energy) web site displays the results of a survey of state financial incentives, programs, and regulatory policies designed to promote renewable energy technologies.
