Figure 4.2 - Net annual change in carbon (CO2 equivalent) in UK woodlands
Figure 4.2 shows estimated net annual changes in the amount of carbon in living biomass in UK woodlands, starting in 1990 and including projections up to 2020. Changes are expressed in million tonnes of carbon dioxide. The figure is in the form of a stacked bar chart, showing annual changes for England, Wales, Scotland and Northern Ireland, with a line superimposed showing UK totals. For the period up to 2009, the UK total increases from 9 million tonnes CO2 in 1990 to 13 million tonnes CO2 in 2004, then declines to 8 million tonnes CO2 in 2009. During this period, all countries show positive changes, with Scotland accounting for around two-thirds of the UK total. In the period after 2009, the figures are projected to continue to decrease in all countries, with Wales being the first to be negative, followed by England and then Northern Ireland. The UK total is projected to become negative in 2020.
