Worst emission offenders

There is more than one way to count your carbon. One way is to consider the relative CO2 emissions of countries — that is, their emissions divided by their population. This graph isn’t a representation of all the top emitters, but a cross-section pulling out some of the more important countries from top to bottom. It shows a striking differences in carbon dependence.

At the top end of the scale, Saudi Arabia’s economy produces almost 20 tonnes of CO2 of per inhabitant every year. Multiplied by its population, and this country of only 30 million is responsible for more nearly 1.7 per cent of all global emissions. The United States, however, is not far behind, at 16.5 tonnes, and with its population of 330 million, it is also a very large contributor in absolute terms. Canada too is up there among the worst carbon offenders, made possible by its high dependence on oil, gas and coal to fuel its industry, drive its transportation networks and heat homes. Many other notable carbon profligate countries were emitted from this graphic, including countries like Japan, Australia and Russia. The highest emissions per capita in the world actually belong to Qatar, Kuwait and the United Arab Emirates. Qatar’s emission rate is staggering: nearly 40 tonnes of emissions per person per year. And though their populations are small, together they still produce more than 1 per cent of all annual emissions.

In the middle of the scale, the European Union’s emissions of only 6.4 tonnes per inhabitant seems modest in comparison. Even China has surpassed the Europeans, though its large population puts it firmly in first place among the world’s biggest emitters. And at the bottom of the scale, we have Sub-Saharan Africa and India, both with more than 1.2 billion people. Most Africans and Indians go without the things that put the Western world, China and the Arab states high on the list, like home electricity, airconditioning, personal transportation and economies based in part on heavy industry. If they want to acquire these things — as is their right — the rest of the world has an obligation to ensure that they can do it without increasing their emisisons.
