This joint study by the International Labour Organisation (ILO) and the United Nations Environment Programme (UNEP) highlights that the transformation to a greener economy could generate 15 to 60 million additional jobs globally over the next two decades and lift tens of millions of workers out of poverty. The report documents evidence that for countries at all levels of development the drive towards environmental sustainability and greener economies is gaining momentum. The study indicates that job growth has been particularly strong in the renewable energy sector, with a global increase of 21 per cent annum. As a result, the sector now employs close to 5 million workers; more than double the number employed only a few years ago.
