While global climate finance has steadily increased over the past decade, reaching a high of\u202f USD 1.46 trillion in 2022<\/a>, much more is needed to keep\u202fglobal temperature rises within 1.5\u00b0C by the end of this century and avoid\u202fthe worst impacts of climate change.\u202f <\/p>\n\n\n\n

Timely and accurate information on climate investment flows and needs is key to creating awareness among public and private investors as well as policymakers and ensuring that climate investments are channeled toward those sectors and countries that display the largest funding gaps.<\/strong> <\/p>\n\n\n\n

Since 2021, CPI has been building a collective understanding of the climate finance needed to reach net-zero carbon emissions by 2050. We collect and standardize data on climate finance needs from a wide variety of sources to provide the most comprehensive available overview of the current climate finance gap.  <\/p>\n\n\n\n

Top-down needs<\/strong> are estimations of the climate finance required across different sectors to keep the average global temperature rise within 1.5\u00b0C by the end of this century. These needs are typically calculated using predictive models for different sectors. Climate-compatible scenarios developed by different institutions can differ widely in the data, assumptions, model used, and (geographic or sectoral) scope. 

Top-down needs differ from bottom-up needs<\/strong> which are climate finance required by countries to reach their national climate targets, as stated in official documents such as Nationally Determined Contributions (NDCs). CPI\u2019s methodology and data on bottom-up needs are available here<\/a>.  <\/p>\n\n\n\n

How much (more) is needed to keep us under 1.5\u00b0C?<\/strong><\/h2>\n\n\n\n

Our compilation of top-down needs assessments shows that, in an average scenario, annual climate finance flows must increase at least fivefold compared to current levels, <\/strong>reaching USD 7.5 trillion per year between now and 2030, and over USD 8.8 trillion per year from 2031 to 2050. Mitigation investments account for 97% of these estimated needs, in part because adaptation finance needs are largely underestimated (see below).<\/p>\n\n\n\n

Within mitigation, the largest investment gaps, in absolute terms, are observed in the energy and transport sectors, where an additional USD 2.2 trillion and USD 1.4 trillion per year1<\/a><\/sup> will be required, respectively, between now and 2050. In relative terms, the largest gaps are observed in agriculture, forestry, and other land use (AFOLU) and industry, where funding needs to grow by 30 times and 22 times, respectively, compared to 2022 levels. Increasing funding for AFOLU could be especially impactful, as the sector is estimated to have the second-largest mitigation potential, at an average of 8 GtCO2e<\/sub> by 2030<\/a>.<\/p>\n\n\n
