During this time of year, many organizations engage third-party GHG calculations verification for annual submission to regulatory agencies and interested parties as internal sustainability reporting cycles conclude, and external expectations increase from stakeholders and global supply chains. P360’s ISO aligned approach supports organizations seeking credible, independent assurance to help meet these evolving disclosure and oversight requirements.
