Charities are being invited to apply to take part in the Big Give’s Green Match Fund 2024, which aims to raise £10m for environmental causes.
The annual funding event was first held in 2021 and last year raised more than £4.3m for the 178 charities that took part.
Next year’s event, which will run from 18 April to 25 April around World Earth Day on 22 April, aims to support more than 200 charities.
To be eligible for the scheme, charities must be UK-registered, working on environmental issues as part of their core mission and have an annual income of more than £25,000.
Charities wishing to apply to the scheme must complete their registration by 16 January.
There are two models of match funding.
The first is the pledge model which requires a charity to raise pledges from major supporters, up to £100,000, that will form the basis of a match-fund pot.
The Big Give aims to match the amount of money raised in pledges with funding from appropriate “champion funders”.
Champion funders are organisations with existing relationships to Big Give and provide the funds that match pledges and donations to a cap of £50,000.
They include The Reed Foundation, The Waterloo Foundation and Monday Charitable Trust.
The deadline for raising pledges is 2 February, after which the Big Give will complete due diligence checks on applications and pass them on to a panel of experts who will review them and assign “champion funding” before 14 February.
When the event begins on 18 April, charities ask supporters to make donations on the Big Give website that will begin to release the match-funding pledged in advance, as well as the money pledged by the champion funders.
The other model is 1:1 funding, which does not include the pledging phase and has a match-funding cap of £10,000.
This means that donations made during the event will be matched by solely champion funders that have agreed to the model.
Big Give said it was providing a free suite of resources to help support charities to maximise the opportunity and market the campaign.
Alex Day, managing director of the Big Give, said: “We are pleased to launch our fourth annual Green Match Fund in aid of environment charities across the UK and internationally.
“This will be our biggest and boldest funds target yet as, more than ever, it’s vital that we support charities working to address the pressing environmental and ecological issues facing us all.
“Moreover, this campaign shines a light on this critical area that is often unnoticed by philanthropists.”
The Big Give has raised more than £233m for 14,000 different charities in the past 15 years with its biggest annual event, the Christmas Challenge, raising nearly £29m in one week in 2022.
