In Cancun, European leaders were often left on the sidelines, with little new to offer beyond their 20% emission cut, agreed in 2008. This carbon target is now insufficient to make Europe a player in the clean tech markets – a 30% target is the minimum needed to drive private sector investment into the sector.This assertion seems to be supported by no evidence whatever. Why would a 20% emissions cut not be enough to drive private investment in green tech, but a 30% cut would? For that matter, why would Europe's emissions targets even be a major influence on private investment - presumably if there's a market in the US and China, European companies will still want to capture a share of it?
After 19 years on the Internet, I shouldn't be all that outraged that someone published an unsubstantiated opinion. I don't really even disagree with the basic point about reducing emissions. It's just a shame that Greenpeace couldn't be bothered to marshal any of the good arguments for it.
