the per capita co2 emission is the highest in world

title: Greenhouse gas text: consumers in the US, Japan, and Western Europe. Based on annual emissions data from the year 2004, and on a per-capita consumption basis, the top-5 emitting countries were found to be (in t per person, per year): Luxembourg (34.7), the US (22.0), Singapore (20.2), Australia (16.7), and Canada (16.6). Carbon Trust research revealed that approximately 25% of all emissions from human activities 'flow' (i.e., are imported or exported) from one country to another. Major developed economies were found to be typically net importers of embodied carbon emissions—with UK consumption emissions 34% higher than production emissions, and Germany (29%), Japan (19%) title: Climate change in the United States text: produced 6,930 mt (15.7% of the world's total). In the cumulative emissions between 1850 and 2007, the U.S. was at the top in terms of all world nations, involved with 28.8% of the world's total. China's emissions have outpaced the U.S. in CO2 from 2006 onward. The U.S. produced 5.8 billion metric tons of CO2 in 2006, compared to the 6.23 billion coming from China. Per capita emission figures of China are about one quarter of those of the U.S. population. The single largest source of greenhouse gas emissions in the U.S. is power generation. For example, data from 2012 title: Energy in Australia text: and abroad. This in turn has led to a decrease in the demand of coal worldwide. In 2009, Australia had the highest per capita CO2 emissions in the world. At that time, Maplecroft's CO2 Energy Emissions Index (CEEI) showed that Australia releases 20.58 tons of CO2 per person per year, more than any other country. Since that time, however, emissions have been reduced. From 1990 to 2017, emissions per capita fell by one-third, with most of that drop occurring in the more recent years. Additionally, the emissions intensity of the economy fell by 58.4 percent during the same time period. title: Contribution to global warming by Australia text: Contribution to global warming by Australia Australia has one of the highest per capita emissions of carbon dioxide in the world, with 0.3% of the world's population it produces 1.3% of the world's greenhouse gases. It was 18.3 tonnes per year per person and the 11th highest in the world per capita in 2009. Australia uses principally coal power (70%) for electricity, with the remainder mainly gas, with no nuclear, low levels of hydro power, and low, but increasing, levels of solar, wind and wave power. The Australian government estimates that Australia's net emissions in 2006 were 576 million tonnes title: Energy policy of China text: the People's Republic of China calculated that carbon dioxide emissions in 2004 had risen to approximately 5.05 billion metric tons, with total greenhouse gas emissions reaching about 6.1 billion metric tons carbon dioxide equivalent. In 2002, China ranked 2nd (after the United States) in the list of countries by carbon dioxide emissions, with emissions of 3.3 billion metric tons, representing 14.5% of the world total. However, due to its huge population size (the largest in the world), it only ranked 43 in the list of countries by carbon dioxide emissions per capita, with emissions of 7.6 metric tons per person
