Average annual flow of climate finance in 2021 and 2022 was $1.3 trillion, twice the $653 billion of 2019 and 2020.
Renewable energy (RE) and transport continue to display most growth, with the former comprising 44 per cent of total mitigation finance and the latter 29 per cent of it.
The United States, Europe, Brazil, Japan, China and India received 90 per cent of the funds for clean energy.
Adaptation finance has reached an all-time high of US $63 billion.
But still does not measure up to the estimated needs of $212 billion per year by 2030 just for developing nations.
East Asia and the Pacific, US and Canada and Western Europe accounted for a total of 84 percent of all the climate finance.
Developing and low-income countries continue to face a paucity of funds. Less than 3 per cent of a total $30 billion went to or within least developed countries.
The 10 countries most affected by climate change between 2000 and 2019 received just $23 billion; less than 2 per cent of total climate finance.
