What are the rules around buying EACs internationally?

Yes, buying EACs from another country is allowed under most reporting standards. But to maintain credibility and avoid greenwashing concerns, follow these best practices:

Match regionally whenever possible — ideally within the same country, grid, or continent.
Be transparent about the origin of the EACs in your reporting.
Check the rules of programs you report to (like SBTi or CDP), as they may require geographic alignment or higher-impact certificates.
