A “bottoms-up” approach when it comes to cleantech is helping the fight against climate change, the Danish energy minister said today.

His comments come as he joins around twenty energy ministers from around the world at the Clean Energy Ministerial in London to discuss the progress of developing new renewable and low carbon technology.

Martin Lidegaard said at the WWF briefing on cleantech: “It’s frustrating how slowly things are moving from a top down approach [with UN climate agreements]. But it’s encouraging from a bottoms up perspective where things are moving.”

He said the growing investment in cleantech and decreasing prices of some technologies such as solar power were very important.

Germany’s delegate at the talks, Dr Karsten Sach (pictured) suggested “incentivising first movers” was going to be crucial to generate the investment which banks might be reluctant to give out.

For this, he said investors and industry “need stable framework”, especially when developing far better, smarter, more efficient grids and support when it comes to “radically” improving energy efficiency.
