The World Development Movement have created a calendar to promote climate change. It’s a CO2 calendar that shows “when during 2007 the average UK citizen will have emitted as much as a citizen from another country will during the whole year”. So by today (5th February) UK citizens will have emitted as much CO2 as an El Salvador citizen does in a year!
The closest countries to the UK in terms of CO2 emissions per citizen, according to the calendar, are Turkmenistan and New Zealand! Other dates of interest are China (18th May), Brazil (10th March), Iran (14th August) and India (9th February). The United States and Australia are both not on the calendar!
