What this scam usually looks like

In this scam, a firm sells carbon credits or 'green' investments as a fast-growing, ethical opportunity, but the credits are overpriced, illiquid, or worthless, with guaranteed returns that never materialise.

Crypto and investment scams promise high or guaranteed returns with little risk, usually through fake platforms that display staged gains. Small test withdrawals build trust before you are pushed to invest more, then blocked from withdrawing behind endless "fees" and "taxes".

The single clearest warning sign to remember is this: A cold pitch to invest in carbon credits with guaranteed or high returns. Verify the firm and the market independently; be wary of guaranteed returns.
