CAFAmerica's receipts rose by 82 per cent in 2004/05 as US donors showed renewed interest in international philanthropy.
The financial services organisation, which channels giving from US corporations and people to charities worldwide, saw its receipts from charitable contributions reach $15.8m (£8.8m) in 2004/05. This is up from $8.7m (£4.8m) in 2003/04.
UK charities received more than half of the money. In Britain, $7.8m (£4.3m) was given in 789 grants to voluntary organisations.
EU charities received 79 grants totalling $1.9m (£1m). Overall 1,474 charities in 43 countries received grants. There are now 951 eligible UK charities and 79 EU ones - organisations that have successfully applied to become part of CAFAmerica's list of approved organisations.
"We are seeing increased interest in international philanthropy on the part of US donors, as well as an increased confidence in CAFAmerica as a vehicle for safe, easy and effective giving overseas," said CAF-America executive director Susan Saxon-Harold. She said many donors looked to CAFAmerica as a trusted intermediary to satisfy new requirements on checking overseas organisations in receipt of grants.
"CAFAmerica is increasingly being seen as a leader in terms of the due diligence it does on foreign charities, which builds donor confidence," she said.
CAFAmerica reported increased grant-making to China, India and South America.
