Investment in the green sector rose by 7% this year, as more renewable energy capacity is installed worldwide.
Finance in clean energy projects totalled £34.7bn, a 21% increase driven by a surge in the Asia-Pacific region. It saw a record volume of £15.6bn of investment.
Brushing aside the challenge of sharply lower crude oil prices, this sudden increase reversed the investment dip of the past two years and saw the highest gains in wind and solar energy.
Output from the renewable energy sector saved about one million tonnes of carbon emissions each month last year.
