Those interested in the full details of the European climate agreement reached last week in Brussels can examine it in all of its gory details here. It is, to put it mildly, complicated. So in the interests of those just wanting the bottom line, here I offer a simplified version of the policy. The emissions reduction goal is 20% below 1990 emissions levels. As the graph below shows (from the EEA), Europe has a head start on this goal as emissions have decreased since 1990, especially because of the enlargement of the EU to include eastern European countries. So to achieve the goal Europe actually needs a further reduction of about 12% from 1990 levels. The plan allows European countries to offset 3% or 4% of their emissions reductions via paying for emissions reductions in developing countries (a dodgy proposition, but I digress). This means that the emissions reductions will not occur in Europe. So this reduces to the goal to about 9%. The agreement allows countries to exceed their annual emissions targets by 5% annually. So this extra headroom reduces the total emissions reduction goal to about a 4% reduction (very similar to what WWF calculates). A 4% reduction is not so far from business as usual (under some projections), which of course is why the package passed.
