Those are vital contributions, and while I can't vouch for the fact that this would be the latest number, I would point out that the last I've seen is somewhere to the tune of four per cent. That's the slice of the pie that the environmental charitable sector receives out of all donations. Given the twin crises of climate change and biodiversity collapse, four per cent of the total pie is not a huge number so anything that charitable organizations can do to build momentum and build support from individuals, and to diversify their funding base, of course, is welcomed.
