Dirty deeds: The world's biggest polluters by country

US carbon dioxide emissions rose slightly in 2013 following years of decline.

Bad news for the environment.

After years of decline, US carbon dioxide emissions increased slightly last year, according to a new report by the US Energy Information Administration.

That said, America is still a little better than the world's worst polluter: China.

The 2 percent jump in CO2 emissions in the United States was largely the result of higher natural gas prices last year, which prompted some utilities to switch back to a dirtier energy source — coal, according to The Washington Post.

America's CO2 emissions had fallen 12 percent from 2007 to 2012 before the latest report.

Here, we take a look at the world's five biggest polluters, according to CO2 emission estimates in 2012 from the EU-based Emission Database for Global Atmospheric Research.


1. China

China overtook the United States as the world's biggest carbon dioxide polluter in 2006, and has topped the list ever since.

In 2012, the communist country pumped an estimated 9.8 billion tons of CO2 into the world's atmosphere from the burning of fossil fuels such as oil and coal. And while emissions grew at a slower pace in 2012 than previous years, China still accounted for 70 percent of the global increase in CO2 emissions that year.

China's smog levels are notorious. But air pollution is soaring to new heights due to the country's rapid industrialization, reliance on coal power and increased car ownership for a booming population.

It doesn't help that environmental laws are often ignored, according to green activists.

As stated above, America's carbon dioxide emissions had been going down for years. The decline can be partly attributed to the economic recession, improved energy efficiency, and the shale-gas boom.

Emissions reached a 20-year low of just under 5.2 billion metric tons in 2012.

But new figures show CO2 emissions actually increased 2 percent in 2013 as more utilities turned to coal for energy after a steep rise in natural gas prices.

Emissions are still 10 percent below 2005 levels, but they were once down 12 percent. The Obama administration set a goal of being 17 percent below 2005 levels by 2020.

Suddenly, that goal looks like a steeper climb.


3. India

India's carbon dioxide emissions shot up 7.7 percent in 2012, with those from coal growing at an even faster pace of 10.2 percent.

That despite the South Asian country recording its lowest GDP growth — 4 percent — in a decade.

One in three Indians currently live in "critically-polluted" areas. And of the 180 cities monitored by India's Central Pollution Control Board, just two — Malapuram and Pathanamthitta in Kerala — have what are considered "low" levels of air pollution.


4. Russia

Russia's carbon dioxide emissions plunged after the collapse of Soviet-era smokestack industries, but it remains the world's fourth largest CO2 polluter at 1.7 billion metric tons in 2012.

Hundreds of cities currently exceed pollution limits, with Moscow, St. Petersburg and the far-northern Siberian city of Norilsk among the worst offenders.

Two cities — Norilsk and the central Russian city of Dzerzhinsk — made the environmental group Blacksmith Institute's list of the world's most polluted places this year.


5. Japan

Japan recently watered down its target to cut carbon dioxide emissions despite the 1.3 million metric tons of CO2 it produced in 2012.

The new target, announced in November, reverses course from a goal set four years ago and now allows a 3.1 percent increase in emissions from 1990 levels rather than seeking a 25 percent cut.

It reflects the country's increased reliance on fossil fuels in the aftermath of the Fukushima nuclear disaster in 2011.

I have to call BS on this report! It talks about CO2 emission but nothing about pollution of the waterways that are polluted, ground pollution and general air pollution! Please tell me what city in the USA do you gout out for the day and come back in and take a white wash cloth to your face and have it mostly black like in Shanghai, Moscow, Manila, Kiev, Addis Ababa, Beijing all cities I have been to and I am sure India's major cities are the same. You have to drink bottled water in each of the cities I mentioned above because of the pollution that comes out of the tap water! We all want a cleaner environment but quite playing fast and loose with the facts!

Clean energy? Don't you mean "clean lethargy?"

shouldn't Canada be on the list?

Statistically Canada is quite low in spite of what the media says about dirty oil. Canada is less than 2% of the US's "Dirty Coal Power".

I haven't done the math, but you should have - how do these countries rank on a per-capita basis? My guess is the US is numero uno. You also chose not to list the absolute figures for India. And there's no analysis - why we stand where we stand. Surely this could have been better written with more effort.

Maybe YOU should do the math. #1 *per capita* is actually Australia - followed by the US, Canada, and the Netherlands.
