In practice, there remains a large gap between commitments and funds that have been pledged and disbursed by developed countries. The largest target sector for these flows in 2016 was renewable energy, with a share of 43.3 per cent ($295 billion), followed by energy efficiency with a share of 36.1 per cent ($246 billion), and sustainable transport with a share of 13.5 per cent ($96 billion). Climate finance flows to non-Annex 1 Parties (developing countries) are only a fraction of these total flows, as illustrated in figure 4.1. Total climate finance flows to developing countries, including mobilized private finance, increased by 13.4 per cent between 2015 and 2016, from $61.9 billion to $71.4 billion. Several initiatives that aim to provide an overview of available funds are under way.
