SECR, also known as Streamlined Energy and Carbon Reporting, is a mandatory framework in the United Kingdom that certain large companies are required to follow, disclosing their energy consumption and greenhouse gas (GHG) emissions in their annual financial reports. SECR disclosure is part of the reporting process, recording, analysing and sharing their environmental impact data and the actions they will take to reduce their energy consumption and carbon footprint. The SECR disclosure process was implemented in the UK in April 2019 and is designed to be easy to follow and cost-effective for organisations to follow, often using existing data and processes to comply with SECR requirements. The disclosure of this information allows for comparison of large organisations’ environmental impact, helping to encourage and drive change, with the focus being on reducing carbon emissions and supporting the transition towards a low-carbon economy. Ecometrica has been helping companies disclose to the SECR framework since its introduction.
