Paying people up plant trees, or to use carbon-neutral sources of energy that they otherwise wouldn't. Carbon offsets are currently much cheaper than they really should be, because there's a lot of low-hanging fruit like the latter, but that doesn't mean they're not genuinely causing less CO2 to stay in the atmosphere than otherwise would.
