Historical data and current trend methodology

• Data on climate-related Official Development Assistance for the forestry sector was sourced from the OECD. Data for 2024 is not yet available and is predicted using the average yearly change over the last five years. 

• Data on international REDD+ disbursements was sourced from the Climate Funds Update Data Dashboard. Data includes REDD+ readiness and implementation finance disbursements by the Forest Carbon Partnership Facility (FCFP), Green Climate Fund (GCF), Forest Investment Program (FIP), BioCarbon Fund, Central African Forest Initiative (CAFI), UN-REDD, Congo Basin Forest Fund (CBFF), and the Amazon Fund. 

• Data on disbursements under different forest finance pledges was sourced from progress reports for key forest finance pledges and initiatives by public and philanthropic donors. Figures cover disbursements through September 23, 2025. Disbursements under different forest finance pledges include a small, yet insignificant share of philanthropic finance. 

• The estimate of average annual international public finance for forests post-GLD (2022-2024) is calculated using 2022-2024 data on climate-related Official Development Assistance for the forestry sector, international REDD+ disbursements, and disbursements under different forest finance pledges by public and philanthropic donors.  

• The estimate of average annual international public finance for forests pre-GLD (2018-2020) is calculated using 2018-2020 data on climate-related ODA for the forestry sector (OECD data) and international REDD+ disbursements (data from Climate Funds Update).  

• The period 2018-2020 is used as reference period to align with the reference period used for tracking progress on overarching forest goals; and to exclude the year 2021, in which values deviating from historical trends were recorded, presumably due to the COVID-19 pandemic.
