Wind, wave and solar power, zero-emissions transport, low-carbon buildings and energy-efficiency technologies have all been shown feasible. To be rolled out on a global scale, they are just waiting for the political will.
The barriers preventing the creation of a low-carbon society are not technological but political and financial.
The UK’s Committee on Climate Change, which advises the British government, continues to support the view of theStern report – an assessment of the climate change challenge in the UK – that the move to a low-carbon society will cost no more than 1 per cent of GDP by 2050.
