Streamlined Energy and Carbon Reporting (SECR) requires larger UK companies and LLPs to report energy use and greenhouse gas emissions in their annual report. WeZero calculates UK energy use in kWh and Scope 1 and 2 emissions from your fuel, fleet and electricity data using UK Government (DESNZ) conversion factors, including grey fleet mileage energy. You define intensity metrics such as turnover or employees on the master dashboard, and WeZero assembles the SECR summary table with prior-year comparatives and generates a Word report with an editable, AI-drafted narrative of energy efficiency actions. SECR reporting is included in the Pro plan and above; the underlying carbon calculator is free.
