Accredited Verification for Your Company's GHG Inventory

Understanding your company’s carbon emissions data is vital to managing your carbon footprint. Annual third-party verification of your GHG inventory ensures your reporting is free of material errors giving you much greater confidence in reporting. Verified accounting is vital to management of climate-related risks, identifying cost-saving opportunities and keeping pace with regulatory compliance. Greenhouse Gas verification may soon be required by the SEC and a growing list of other agencies including GSA, the state of California and the EU with their CSRD initiative. Accurate GHG reporting is also increasingly important in supply chains and required by some major retailers. Showcasing your GHG verification in your CSR report also enhances brand reputation and competitiveness and gives stakeholders greater confidence in your reporting.
