This gives 5400kg as the national average for house, car, plane and public transport and was based on 2003 data quoted in Mayer Hillman’s book. If you take out public transport you get about 5200kg. We simply rounded this down to an easy to remember 5000kg and used it as an estimate of where were 12 months ago at the start of the first CRAG year. 4500kg represented the first 10% cut and 4050kg would be the second. However if you are counting public transport your group might have decided to start from a slightly higher figure as Oxford did. They went for 5000kg in 2006.
Hope this clarifies.
90% of last year's target

It’s simply last year’s widely adopted target of 4500Kg – 10% = 4050 Kg
