Penalty estimate = max(0, annual GHG emissions − allowable emissions) × $268 per metric ton. Allowable emissions = (limit for your property type, tCO₂e/sf) × gross square footage. Limits follow published LL97 Category B building emissions coefficients. Actual penalties depend on verified emissions, occupancy classification, and exemptions.
