Tesco is seeking charity partners to receive a portion of the £1.8m it expects to raise from carrier bag levies in Wales and Scotland.
Charities are being invited to submit proposals on how they could work with the supermarket chain and use the funds for causes relating to the environment and communities.
Charities that want to take part must be registered in the UK, with national coverage in Scotland or Wales, and deliver environmental projects on a national scale such as those that encourage sustainable living or local initiatives that benefit communities.
Tesco will either appoint one partner for both countries or one for each.
The retailer said prospective partners must support Tesco’s Scale for Good ambitions – to lead in the global fight against food waste, to help people live healthier lives and create opportunities for young people – and focus their activities on "a cause with national resonance and appeal".
Each partnership, expected to be worth about £1m in Scotland and £800,000 in Wales, will be for an initial period of one year from 1 October.
Mandatory charges for plastic carrier bags are due to be introduced in Scotland from October, and have been in place in Wales since 2011.
Since its inception, Tesco has raised more than £2m from the charge in Wales for the RSPB, which has been used for conservation work.
"The money raised from the bag levy in Wales has already been put to great use by the local RSPB, and we expect successful bidders this time round will also use the money raised to make a huge difference," said Greg Sage, community director for Tesco. "For the first time, charities in Scotland will have the chance to benefit from the bag levy too."
The closing date for applications in 11 July. For more information on the application process, click here.
