Nick Clegg, Britain’s Deputy Prime Minister, has admitted that the Rio+20 deal is “disappointing.” Mr Clegg blamed China and other developing countries that have huge reserves of coal and want to continue using fossil fuels to grow, for failing to back plans for the green economy. “The political significance of Rio is that the G77 nations are antagonistic to our European ideas on the green economy,” said Mr Clegg. He said Europe can no longer take the lead in such international negotiations because power is shifting “from West to East”.
