Greenhouse Gas Emission Sources and Trends
Regulatory Compliance Obligations For the Utility Industry
Fri, 02/04/2011 - 2:25pm — Kevin Lustig
This chart is an adaptation based upon an original chart from Edison Electric Institute (EEI) - see http://www.eei.org/meetings/Meeting%20Documents/EPA-CAAUtilityRegTimelin.... The original EEI chart has been used to suggest that EPA’s regulatory timeline is unworkable. However, as illustrated in http://www.earthtrendsdelivered.org/node/406, the original chart consists mostly of procedural events and activities that will not impose a direct compliance obligation on power plants.
Environmental Regulatory Requirements For the Utility Industry, Removing All But New Compliance Obligations
Fri, 02/04/2011 - 2:24pm — Kevin Lustig
This chart is a reproduction of a chart from Edison Electric Institute (EEI) that has been used to suggest that EPA’s regulatory timeline is unworkable - see http://www.eei.org/meetings/Meeting%20Documents/EPA-CAAUtilityRegTimelin.... WRI has identified four categories of EPA activities on the EEI timeline that are potentially misleading:
(Blue X's) Rules that have been remanded or vacated by court decisions that do not impose compliance obligations.
World steel sector energy intensity index by region, 2005
Fri, 02/04/2011 - 2:22pm — Kevin Lustig
Steel production accounted for nearly 17 percent of China’s primary energy use in 2008. Compared to developed countries’ steel producers, China’s steel sector has much higher primary energy intensity. This higher intensity can be explained by heavy reliance on coal, relatively higher iron alloy production, lower waste energy recovery, smaller scale of equipment, lower conversion efficiency of steam and oxygen, and relatively poor material quality (Huang 2008; Tsinghua Study 2009).
Coal-fired electricity generation versus coal consumption per kWh in China, 2003-2009
Fri, 02/04/2011 - 2:17pm — Kevin Lustig
Coal consistently contributes to over 75 percent of electricity in China (China Bureau of Statistics 2009). To meet its ever growing demands for electricity, China has seen rapid growth of coal-fired power generation. From 2003 to 2009 the country more than doubled its coal-fired generation capacity, making its fleet the largest in the world. However, the fuel consumption per unit of electricity generated during this period has steadily decreased. The use of supercritical/ultrasupercritical technology has significantly contributed to the improvement of energy efficiency.

Forest Cover Loss in Indonesia, 2000-2005: The Starting Point for the Norwegian Billion to Reduce Deforestation
Wed, 07/28/2010 - 1:25pm — jwarner@wri.org
Up to 84% of Indonesia’s national greenhouse gas emissions arise from land use change and deforestation. This map shows the extent and location of forest cover loss in Indonesia—detected by satellite—for 2000 to 2005, when deforestation averaged 0.71 million hectares per year and Indonesia was the second-most deforesting country, following Brazil. Globally, Indonesia accounts for approximately 27 percent of GHG emissions from land use change and forestry.

Energy use is the largest driver of GHG emissions, primarily the burning of fossil fuels in the electricity generation, transportation, and industrial sectors. This graphic depicts the contributions of major economic sectors to total energy-related GHG emissions in the state of Virginia in 2007.

Per Capita GHG Emissions in the U.S. in 2007

The activities of our everyday lives are critical to determining the magnitude of GHG emissions and, hence, global warming. How much electricity we use, what type of car or how often we drive, and our consumption of goods are some of the most tangible drivers of GHG emissions. As consumers of natural resources, our habits and actions directly and indirectly produce GHG emissions and will become more acute as populations continue to grow.
