Predictability of support for climate and sustainable development can provide greater clarity and certainty, enabling longer term planning at the national level. Unfortunately public funds for climate and development have been quite unpredictable in recent years due to the global economic downturn. Agreeing credible pathways to deliver on the commitments made by developed countries to provide 0.7% of GDP as development assistance, as reaffirmed in the Addis Ababa Action Agenda, and mobilising the USD 100 billion / year by 2020 for climate action in developing countries made under the UNFCCC, will help to improve predictability.
