The world’s largest carbon-trading market may awaken from its coma: politicians in Europe’s parliament today agreed a plan to revive market prices which have collapsed in the recession.
It’s a change-of-heart from a parliament which had rejected the same idea in April. But although it would lift the market out of total irrelevancy, the plan still won’t raise carbon prices high enough to spur investment in low-carbon energy, which was one of the European trading scheme’s key goals when it was launched in 2005. So some politicians say much deeper reforms are needed. What’s more, the plan still needs to be approved by the ministers of Europe’s member states – a decision that won’t be taken until after Germany’s elections in September.
