Generating electricity and heat by burning fossil fuels like coal, natural gas and oil produces more greenhouse gas (GHG) emissions than any human activity, accounting for at least one quarter of all global emissions. CO2 emissions from electricity and heat have increased as coal has been the fastest growing energy source since 2000, reports the International Energy Agency.
The energy policy of China is a policy decided on by the Central Government with regard to energy and energy resources. The country is currently the world's largest emitter of greenhouse gases according to a Dutch research agency. However, China's per capita emissions are still far behind some of the developed countries. In addition, China is also the world's leading renewable energy producer.
Emissions by Country
In 2008, the top carbon dioxide (CO2) emitters were China, the United States, the European Union, India, the Russian Federation, Japan, and Canada. These data include CO2emissions from fossil fuel combustion, as well as cement manufacturing and gas flaring. Together, these sources represent a large proportion of total global CO2 emissions.
Emissions and sinks related to changes in land use are not included in these estimates. However, changes in land use can be important - global estimates indicate that deforestation can account for 5 billion metric tons of CO2 emissions, or about 16% of emissions from fossil fuel sources. Tropical deforestation in Africa, Asia, and South America are thought to be the largest contributors to emissions from land-use change globally.  In areas such as the United States and Europe, changes in land use associated with human activities have the net effect of absorbing CO2, partially offsetting the emissions from deforestation in other regions.
