HB 4068, the Oklahoma Truth in Environmental Marketing Act, requires businesses selling products or packaging in Oklahoma to substantiate environmental claims like "compostable," "recyclable," or "carbon neutral" with reliable evidence (e.g., scientific studies or third-party certifications). It mandates that businesses maintain documentation for five years and disclose specifics like emission calculations and offset verification for "carbon neutral" claims. The Oklahoma Attorney General enforces the law, with penalties up to $2,500 per violation per day for false claims, and collected fines fund enforcement and consumer education. The law applies to all businesses making environmental marketing claims in Oklahoma and takes effect November 1, 2026.
