Other Legislation that may impact you

  • SECR (Streamlined ~Energy & Carbon Reporting) - If you are currently listed on the FTSE Main Market you must  do this. We expect all large entities to be required to do this in the future.

Sustainability & Environmental Reporting

Leading businesses now produce a formal Sustainability or Environmental report - often to support/ complement their Annual Report & Accounts. If you are based in the EU or US you may also be obliged to report under International Carbon Reporting requirements.  

  • You may be asked by your supply chain to complete one for the CDP (formerly known as the Carbon Disclosure Project) or you may voluntarily decide to submit your own.
  • Global Reporting Initiative (GRI) provides a useful (and free!) format/template  to complete Sustainability Reporting - it is well recognised and you can decide whether to make this public or use for internal management
