Earth summit: China 'will set environmental standards'

The United Nations' earth summit wraps up in Rio later on Friday.

At the end of the three-day meeting, development banks are pledging $175bn (£110m) towards initiatives for cleaner transportation and another $150m will be put towards a Latin American renewables fund.

But critics say after the summit, not much will be achieved for the longer term.

Jorgen Randers, the author of '"2052: A Global Forecast for the Next Forty Years'" says the blame will fall on Western countries, who have failed to implement climate friendly proposals and that China will be the world leader in the next decade, when it comes to environmental initiatives.
