Lord Browne, former BP chief and now managing director of Riverstone, the world’s largest renewable energy fund, yesterday stressed the role that engineers can play in providing a low carbon economy.

“Clever engineering allows us to do more for less with energy,” Lord Browne said at sustainability conference Base London.

“Engineers are a unique human resource available for policy-makers. As a businessman, I greatly value the engineer’s approach to problem solving. It is business and engineering working in partnership that will drive London’s low-carbon revolution.”
