What’s next for the ISO net-zero standard

This is a story about corporate climate policy, not something that affects home energy upgrades directly. It concerns a new international standard for how big companies set and report "net-zero" emissions goals.

The International Organization for Standardization (ISO) is developing a standard, called ISO 14060, that would set rules for large companies claiming to be "net zero" — meaning they cancel out as much greenhouse gas as they produce. The public comment period on the first draft closed September 9. National standards bodies from more than 170 countries had 12 weeks to weigh in, and now ISO will review that feedback. Depending on how much revision is needed, final approval isn't expected until early 2027.

Critics, including a member of the ISO advisory group and researchers at the NewClimate Institute, say the draft has problems. It would require companies to publish a detailed two-year transition plan, which some worry exposes sensitive financial information and could scare off big businesses. Others say the standard is too complex and costly for smaller companies, particularly in developing countries, and that it lacks a firm deadline for companies to actually reach net zero — potentially letting large corporations delay real action indefinitely.

None of this changes any home rebate program, tax credit, or upgrade option available to homeowners right now. It's a corporate accounting and reporting standard still years from finalized, with no direct bearing on household energy costs or improvements.
