International Climate Finance (ICF) results and indicator methodologies.

Background

International Climate Finance (ICF) is UK Official Development Assistance (ODA) funding to support developing countries to reduce poverty and respond to the causes and impacts of climate change. Four UK Government Departments jointly deliver ICF:
- Foreign Commonwealth & Development Office (FCDO)
- Department for Energy Security and Net Zero (DESNZ)
- Department for Science, Innovation and Technology (DSIT)
- Department for Environment, Food & Rural Affairs (Defra)
ICF investments help developing countries to:
- adapt and build resilience to the current and future effects of climate change
- pursue low-carbon economic growth and development
- protect, restore and sustainably manage nature
- accelerate the clean energy transition
The UK has committed to spending £11.6 billion of ICF between financial years 2021 to 2022 and 2025 to 2026 in the third phase of ICF, known as ‘ICF 3’. Previously, £9.8 billion was spent between 2011 to 2012 and 2020 to 2021.

ICF results is an annual publication that reports what ICF investments have achieved against a set of Key Performance Indicators (KPIs). We collect and aggregate results each year from ICF programmes.

ICF results are not official or national statistics. This is because of the range of data sources we use and their variable quality, which are affected by the challenging environments where we work.

We and our partners strive to apply data quality best practices, and we voluntarily follow the Code of Practice for Statistics (https://code.statisticsauthority.gov.uk/voluntary-application) when producing ICF results. Our Statement of voluntary compliance with the code of practice for statistics (https://assets.publishing.service.gov.uk/media/6514427e45e741000dffebbd/Statement_of_voluntary_compliance_with_the_Code_of_Practice_for_Statistics_2023.odt) (ODT, 12.8 KB) demonstrates the steps we have taken to improve the trustworthiness, quality and value of ICF results.

In most cases we report ICF results cumulatively for the whole ICF period, from 2011 to the present year, or for some indicators, from the year they started. We do not publish results for each individual year within that period because we may receive updated values from programmes for previous years, as well as for the current year.

Updates to data are common and expected for a number of reasons, such as data lags between programmes starting and delivering results or getting confirmation of results data from partners.

Methodology notes

ICF KPI methodology notes guide programme teams, delivery partners and analysts in designing and managing programme monitoring for ICF results. They provide some flexibility to accommodate the range of ICF programmes, while introducing standard definitions and approaches.

Evaluation reports

Learning is essential to achieve maximum impact and value-for-money of ICF. Under a cross-departmental ICF monitoring, evaluation and learning programme, we delivered three independent evaluations to address evidence gaps related to the ICF portfolio .

Portfolio evaluation 1: Integration of International Climate Finance (ICF)

This portfolio evaluation looked at how integrating climate finance within development programmes achieved climate change outcomes.
