Top Emitters of CO2 from Electricity and Heat, Total and Per Capita, 2006

Electricity and heat accounts for approximately 25 percent of global greenhouse gas emissions, making it the largest sector. This chart shows the top 25 emitting countries (including the EU-27) of electricity and heat-related CO2 emissions, in both absolute and per capita terms. Together, these countries account for 91 percent of global emissions from this sector, with the ten largest emitters accounting for 81 percent of the global total.

Major Climate Change Risks and Opportunities in the Forest Products Industry

Though the forest products industry as a whole may stand to gain, climate change will impact companies and investments differently based on the location of the forests, mills, and markets, the vertical integration of assets, and the sustainability of forest operations. This figure illustrates these risks and opportunities in a qualitative way with respect to their potential financial impact and the level of certainty.

Change in Emissions Intensity, 1992 to 2006 of the Top 25 Emitting Countries

Carbon dioxide (CO2) emissions intensity—the level of CO2 emissions per unit of economic output—varies widely across countries, reflecting differences in economic structure, energy efficiency, and fuel mix. For example, among the major emitters, CO2 intensity varies almost sixfold—from 204 tonnes per million international dollars (PPP) gross domestic product (GDP) in France, to 1,124 tonnes in Ukraine.

Change in GDP and CO2 Emissions, Top 25 Emitting Countries, 1992 to 2006

Absolute emissions levels are most strongly influenced by GDP shifts. When GDP rises, emissions also tend to rise correspondingly. Because of this correlation, projections of carbon intensity tend to exhibit less uncertainty than absolute emissions forecasts.

Per Capita CO2 Emissions and Per Capita GDP for the Top Ten Total Emitters and Top Ten Per Capita Emitters, 2006

Only a handful of the countries with the largest total emissions also rank among those with the highest per capita emissions. Estimates of carbon dioxide (CO2) emissions per capita for the top 10 emitters and the top 10 per capita emitters for 2006 are shown here. However, for some countries, per capita emissions vary significantly when CO2 from land-use change and forestry and non-CO2 gases are taken into account. Although per capita emissions are generally higher in wealthier countries, there are notable and diverse exceptions.

CO2 Emissions for Annex I and Non-Annex I Countries: 1990, 2006, and Projected to 2025

Projections of long-term GHG emissions growth depend heavily on assumptions about critical factors such as economic and population trends and the rate of technology development and diffusion. Projections at the national level can be highly uncertain, and the uncertainties are especially acute in developing country economies, which tend to be more volatile and vulnerable to external shocks. The range in projections reflects both differing assumptions, for instance with respect to future policy choices, and substantial uncertainties, particularly regarding economic forecasts.

Coal, Oil, and Natural Gas Consumption by Country (Top 5) and by Sector, 2007-2008

COAL
The top 25 GHG emitting countries collectively account for approximately 92 percent of global coal consumption (BP, 2009). Coal mining and use is highly concentrated. Five countries account for nearly three-quarters of worldwide consumption. Unlike oil and to some extent natural gas, most coal is consumed domestically.

Energy Intensity in 2006 and Fuel Mix in 2007 for Selected Major GHG Emitters

Emissions intensity is a composite indicator of two other major factors contributing to a country’s emissions profile: energy intensity and fuel mix.
