World's energy as dirty now as 20 years ago: IEA

PROGRESS towards the use of cleaner fuel technology has stalled, with production of the world's energy as "dirty" now as it was two decades ago, the International Energy Agency said Wednesday.

Two-thirds of greenhouse gas emissions come from the energy sector and the lack of change should "serve as a wake-up call", the IEA's executive director Maria van der Hoeven told a Clean Energy Ministerial meeting in New Delhi.

She warned that the world needed to act fast "to avoid a potentially catastrophic warming of the planet".
