We're saving £5 of energy a year - that's all

In March we posted that UK residential CO2 emissions were 500 years off target. Apologies. It turns out that we are in fact only 369 years off target - as shown below. The trend rate of improvement since the year 2000 is 0.4% per annum. In other words, since there are 27 million households in the UK, we're cutting our actual CO2 emissions by about 25 kg per household per year. 

Another way of looking at this: the total impact of all UK energy saving policies is about £5 of energy saved per household, per annum. Now, that's not a figure you'll hear quoted very often in the House of Commons.
