East Anglia: Businesses urged to embrace the need for a low-carbon economy - Business - East Anglian Daily Times

Lord Deben was delivering the keynote speech at the New Anglia Local Enterprise Partnership (LEP) Green Economy Conference, taking place at Wherstead Park, near Ipswich.

He told the audience of more than 200 delegates that the science behind climate change was “as sure as any science can be” and that those who styled themselves as climate change sceptics – who he preferred to call “climate change deniers” – were only sceptical about those facts which were inconvenient.

Climate change deniers argued that the changes required in switching to a low carbon economy were too expensive when, in fact, they represented the most cost effective way of meeting the economic challenges of our time, said Lord Deben.

Claimate change was “the biggest threat but also the biggest opportunity that any generation has ever had”, he concluded.
