Top CO2 polluters and highest per capita

The biggest absolute emissions come from China and the United States. In terms of CO2 emissions per capita, China is ranked only ranked 47th, at 7.5 metric tonnes per capita. The US is ranked 11th at 16.5 per capita and amongst countries with sizeable populations, has the highest CO2 emissions per capita. India is the third highest country in terms of absolute emissions, but only 158th in terms of per capita output with 1.7 metric tonnes per capita.

What explains variation in CO2 emissions per capita?

  • Levels of GDP. Countries with higher real incomes can afford to use more petrol and industrial production which causes pollution. By comparison, the lowest income countries have very limited industrial production and consumption of oil. However, that is only one factor, for example, the Netherlands has double CO2 emissions than France with similar GDP per capita.
  • Focus of economy. Economies based around oil  (like Qatar, Bahrain and United Arab Emirates) have the highest levels of CO2 per capita. Qatar has a rate of 45.4 (off the chart) – small population but production based around oil exploration and oil refining.
  • Transport policy. Levels of petrol tax and balance of transport modes can influence CO2 emissions. Countries with highest levels of car use lead to more CO2 emissions. (See: relative petrol prices around the world, e.g. compare US with western Europe)
  • Policies to reduce CO2 emissions. To meet global warming targets countries have adopted policies, such as carbon tax and regulation to reduce pollution.
  • Modes of Power generation. The burning of fossil fuels (e.g. coal-powered electricity stations) is one of biggest causes of CO2 emissions. Countries which gain energy from renewables have lower CO2 emissions per capita.

Readers Question: Why don’t countries use the carbon tax?

  • Taxes are generally politically unpopular. A tax on carbon emissions will affect the living costs of many people. This can make the government reluctant to impose the tax.
  • There is also the free rider problem. A small country may think – what is the point in introducing carbon tax when their CO2 emissions are dwarfed by other countries like China and the US? Especially, when these bigger countries don’t seem inclined to do too much about the issue.
  • There is also differing opinions about the potential cost of CO2 emissions to the environment. In the US, there is a strong lobby which argues global warming is not scientifically proven. Therefore, there is a resistance to impeded CO2 emissions.
  • Another factor is that there are significant vested interests in the oil industry / other industries which pollute. They fear CO2 tax will reduce their profitability so they are willing to fight against moves to introduce taxes.
  • Another argument used is that a Carbon tax will harm jobs.

One thought on “Top CO2 polluters and highest per capita

  1. Lowest CO2 per person is not a crieteria, more populous country will have the least value. Total emissions must be a guide. However thermal power plants and number of vehicles and Air- traffice in a country must be correlating parameters. Further Natural emissions for an acre in wet lands must be eliminated from imposing penalities on a country for excess carbon production
