The world’s top 10 polluters, ranked by their absolute and per-capita greenhouse gas (GHG) emissions, according to the International Energy AgencyNo.1 China
The world’s biggest CO2 emitter.In November 2009 China announced that it will reduce its carbon intensity 40 to 45 percent by 2020.
No.2 United States
USA the world’s second biggest CO2 emitter. The US has 4% of the world’s population but they produces about 25% of all carbon dioxide emissions.
No.3 Russia
Russia has improve its planning to reduce greenhouse gas emissions
No.4 India
India announced that it will reduce its emission intensity by 20-25 percent by 2020 from the 2005 level. India’s emissions intensity is already lower than other emerging economies and had decreased 17.6 percent between 1990 and 2005.
No.5 Japan
Japan, the world’s fifth-biggest greenhouse gas emitter, announced in June this year that it will target a cut in emissions by 15 percent by 2020 from 2005 levels. Japanese businesses argue that their factories are already among the world’s most energy-efficient and that the country will struggle to cut greenhouse gas emissions
No.6 Germany
the world’s sixth biggest greenhouse gas emitter. The Germany government established a mechanism for ending the use of nuclear power over the next 15 years; government working to meet EU commitment to identify nature preservation areas in line with the EU’s Flora, Fauna, and Habitat directive
No.7 Canada
No.7 Canada
The province of Alberta is Canada’s top polluter as of May 2007. The province, with 10% of Canada’s population, contributes 40% of climate-warming gases of the country. It is where seven of the top ten polluters of the country is located, including Syncrude and Suncor. Because half of all emissions in Canada are from industries, environmentalists target them instead of consumers.
No.8 Britain
The nation has met Kyoto Protocol target of a 12.5% reduction from 1990 levels and intends to meet the legally binding target and move toward a domestic goal of a 20% cut in emissions by 2010.By 2005 the government reduced the amount of industrial and commercial waste disposed of in landfill sites to 85% of 1998 levels and recycled or composted at least 25% of household waste, increasing to 33% by 2015.
No.9 South Korea
South Korea announced its first greenhouse gas reduction target in November 2009, pledging to cut emissions of carbon dioxide and other heat-trapping gases by 4% below 2005 levels by 2020.South Korea is one of the world’s largest greenhouse gas emitters. In 2005, the country released 590 million tons of the greenhouse gases blamed for dangerously warming the globe.
If no action is taken to cut emissions, South Korea is expected to produce 813 million tons of greenhouse gases in 2020.
No 10. Mexico
The environmental issues that plague Mexico include scarcity of hazardous waste disposal facilities; rural to urban migration; natural fresh water resources scarce and polluted in north, inaccessible and poor quality in center and extreme southeast.
The nation also has raw sewage and industrial effluents polluting rivers in urban areas; deforestation; widespread erosion; desertification; deteriorating agricultural lands; serious air and water pollution in the national capital and urban centers along US-Mexico border.
