China and America are more than half the problem alone in emissions.

Also a reduction in emissions of at least 34% by 2020.

The choice of how to achieve a 10% cut in your emissions next year is down to you.

This is a 20% increase in emissions relative to the 2010 level.

So a 10% fall in emissions per person would be more than wiped out.

China was responsible for most of global growth in emissions during this period.

However, with our help the developing countries must slow the rate of increase in their emissions.

This means a 25-40% reduction in their emissions by 2020 from the 1990 level.

The national statistics show a 7.5% annual growth in emissions between 1997 and 2010.

This would be followed by a 10% reduction in emissions between 2015 and 2020.
