We seem to be sleep-walking into the future with no real attempts to move away from a carbon based energy economy. Oil and gas are very heavily subsidised I believe in many western nations, so there is no imperative to make a switch to more sustainable energy sources. This being so we need to either change (fast) or move to measures that will mitigate the effects of high carbon use.
The UK looks to have been granted EU money (300M euros) to support a pilot project (see BBC report linked). This takes CO2 from coal power station emissions and buries it under the North Sea. If successful, CCS could be a useful technique as we make the switch to a lower carbon energy economy.
We tend to forget the positive side of EU membership.
