The Global Landscape of Climate Finance 2013 finds that global climate finance flows have plateaued at US$ 359 billion, or around US$ 1 billion per day – far below even the most conservative estimates of investment needs. The report found that on one hand, there is some cause for optimism: Although private investment has declined in general terms, technology costs for large-scale renewable energy have fallen further, perhaps as economies of scale start to take hold. On the other hand, climate related investments have fallen well short of even the most conservative needs estimates for successive years, making the requirement of ‘catch up’ very real.
