On 6 October 2010, the International Energy Agency released for free download the 2008 numbers for over 140 countries/regions/economies. [1]
The list of countries below is arranged by their ratio of gross domestic product (GDP), nominal and by purchasing power parity (PPP), to carbon dioxide emissions. GDP data is for the year 2006 produced by the International Monetary Fund. Carbon dioxide emissions data is for 2006, provided by the CDIAC for United Nations (see List of countries by carbon dioxide emissions).
The countries at the top of the list are the most efficient. They produce the most economic output with the least emissions. Countries at the bottom of the list produce the most emissions per unit of economic output.
Rank | Country | Annual CO 2 emissions (in thousands of metric tons) | GDP (current, in billions of US dollars) | GDP per Emissions (in US dollars per ton) | GDP (PPP, in billions of current international dollars) | PPP GDP per Emissions (in international dollars per ton) |

General:
A carbon tax is a tax levied on the carbon content of fuels and, like carbon emissions trading, is a form of carbon pricing. The term carbon tax is also used to refer to a carbon dioxide equivalent tax, the latter of which is quite similar but can be placed on any type of greenhouse gas or combination of greenhouse gases, emitted by any economic sector.
An emission intensity is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP). Emission intensities are used to derive estimates of air pollutant or greenhouse gas emissions based on the amount of fuel combusted, the number of animals in animal husbandry, on industrial production levels, distances traveled or similar activity data. Emission intensities may also be used to compare the environmental impact of different fuels or activities. In some case the related terms emission factor and carbon intensity are used interchangeably. The jargon used can be different, for different fields/industrial sectors; normally the term "carbon" excludes other pollutants, such as particulate emissions. One commonly used figure is carbon intensity per kilowatt-hour (CIPK), which is used to compare emissions from different sources of electrical power.
A carbon footprint is historically defined as the total emissions caused by an individual, event, organization, or product, expressed as carbon dioxide equivalent. Greenhouse gases (GHGs), including carbon dioxide, can be emitted through land clearance and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, transportation and other services.
This is a comparison between U.S. states and sovereign states' Nominal Gross Domestic Product for the Alternative Future as based on International Monetary Fund and Bureau of Economic Analysis data. Many of the states of the United States have large gross domestic product which would rank highly on a list of countries world GDP.
Electric energy consumption is the form of energy consumption that uses electric energy. Electric energy consumption is the actual energy demand made on existing electricity supply.
A low-carbon economy (LCE), low-fossil-fuel economy (LFFE), or decarbonised economy is an economy based on low carbon power sources that therefore has a minimal output of greenhouse gas (GHG) emissions into the biosphere, but specifically refers to the greenhouse gas carbon dioxide. GHG emissions due to anthropogenic (human) activity are the dominant cause of observed global warming since the mid-20th century. Continued emission of greenhouse gases may cause long-lasting changes around the world, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems.
Norway is a large energy producer, and one of the world's largest exporters of oil. Most of the electricity in the country is produced by hydroelectricity. Norway is one of the leading countries in the electrification of its transport sector, with the largest fleet of electric vehicles per capita in the world.
The United States produced 5.46 billion metric tons of carbon-dioxide equivalent greenhouse gas (GHG) emissions in 2018, the second lowest since the early 1990s, but still the second largest in the world after greenhouse gas emissions by China and among the worst countries by greenhouse gas emissions per person. From year to year, emissions rise and fall due to changes in the economy, the price of fuel and other factors. The US Environmental Protection Agency attributed recent decreases to a reduction in emissions from fossil fuel combustion, which was a result of multiple factors including switching from coal to natural gas consumption in the electric power sector; warmer winter conditions that reduced demand for heating fuel in the residential and commercial sectors; and a slight decrease in electricity demand.
The Kaya identity is an identity stating that the total emission level of the greenhouse gas carbon dioxide can be expressed as the product of four factors: human population, GDP per capita, energy intensity, and carbon intensity. It is a concrete form of the more general I = PAT equation relating factors that determine the level of human impact on climate. The Kaya identity is both simple and tricky, as it can be reduced to only two terms, but it is developed so that the carbon emission calculation becomes easy, as per the available data, or generally in which format the data is available.
The 2008 United Nations Climate Change Conference took place at PIF Congress Centre, Poznań International Fair (PIF), in Poznań, Poland, between December 1 and December 12, 2008. Representatives from over 180 countries attended along with observers from intergovernmental and nongovernmental organizations.
A global recession is recession that affects many countries around the world—that is, a period of global economic slowdown or declining economic output.
A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F). The atmospheres of Venus, Mars and Titan also contain greenhouse gases.
