One option: companies committing to 24/7 carbon-free power (CFE), who don't just reduce their own emissions, but trigger technology learning and emissions reductions in the wider system.

In general, the rules are based on a strong set of environmental safeguards to ensure "clean" hydrogen is truly clean & provide the certainty industry needs to build.

Indeed, here is what Meta's spokesperson told RTO Insider... "Meta’s 100% clean energy commitment uses methodologies from the Greenhouse Gas Protocol. Annually, Meta matches its electricity use with 100% clean and renewable energy on an annual basis based on megawatt-hours,"
Current corporate carbon accounting practices make this entirely compatible with a hypothetical zero-emissions claim by Meta for the exact same data center.
