Banks will have to supply 2 per cent of Europe’s GDP, or €2.9 trillion, to meet consumer (sic) demand for projects and technologies that tackle climate change, according to a new report from Barclays and Accenture. The biggest chunk of the financing would go to solar and wind power infrastructure, which could suck up €617bn as the technologies become more efficient and widespread.  But there are two bits of bad news: 1) there is little evidence that the financing will be forthcoming and 2) even if it is, this amount is unlikely to be enough for the EU to meet its 2020 emissions targets.
