Disclaimer: This tool provides a simplified estimate using publicly available LL97 carbon factors and limits. If pre-filled from LL84 data, figures reflect self-reported benchmarking and may not match current consumption. Results are for informational purposes only and should not be relied upon as legal or compliance advice. Building-specific factors, RECs, adjustments, and rule amendments may affect actual obligations.
