David Dent, founder and chief executive of Votiva, set up to run a scheme called Pennies4Change, said he was in discussion with UK banks and retailers and was trying to encourage them to back the scheme publicly. He said having the support of charity shops could help to create momentum.
"Charities are in a unique position to encourage uptake by retailers, having direct links both with particular stores and supporters, who are also consumers," said Dent.
Earlier this year, 130 MPs backed the scheme, which, according to consumer research, would generate £112m a year with a 4 per cent uptake (7 May, page 3).
Dent is also looking for four or five trustees for the foundation that will distribute the funds raised. Anyone interested in joining the board should email email@example.com.
