Lord Stern, author of the Stern Review (2006), a government report which was used as the basis of UK climate policy, now says we need a four trillion dollar per annum carbon tax to save the world from CO2.
Climate change: $4 trillion carbon tax is needed to save humanity from global warming, say economists
World Bank-backed report says revenue could be used in a number of ways, such as paying out household rebates, alleviating poverty and fostering low-carbon infrastructure

A global carbon tax that would raise trillions of dollars if applied across the world should be introduced if the world is to avoid dangerous climate change, 13 leading economists have said in a new report.
Led by Professor Nicholas Stern, who produced the groundbreaking Stern Report in 2006, and Professor Joseph Stiglitz, who won the Nobel Prize for economics in 2001, the experts suggested a price for a tonne of carbon dioxide of $50 to $100 (£39-78) by 2030.
If implemented all over the world, the top price would raise about $4 trillion – more than the UK’s and Germany’s gross domestic products, but less than Japan’s – although the report suggested poorer countries might charge less.
Currently about 85 per cent of carbon dioxide emissions are not subject to a tax – while the fossil fuel sector receives subsidies of up to an estimated $5.3 trillion. The world’s largest carbon pricing scheme is in the EU, but it only charges about $6.70.

So much for claims that renewables are “free energy”.
