How much will it cost the European Union to fight global climate change? Clearly, the answer depends on what your target is, how you propose to get there, and the size of the EU’s contribution compared with those of the US, China and so on. But a new report from the Centre for European Policy Studies thinktank offers some useful estimates.

The report assesses six recent studies, ranging from the Stern Review and a World Bank analysis to research prepared by Vattenfall, the Swedish energy company. In these reports, the average annual global costs for mitigating and adapting to climate change are put at anything from €230bn to €614bn, based on 2006 data.


The EU is not, these days, one of the world’s great polluters. In 2004, the global economy emitted about 49bn tons of greenhouse gases (measured in CO2 equivalent). The share of the 27-nation bloc was only 5.2bn tons, or 10.6 per cent.

However, as western Europe is one of the world’s richest areas, and as Europe has historical responsibility for the CO2 emissions of its industrial heyday, the EU will surely have to pay more than 10.6 per cent of the global costs of fighting climate change.
