Do Businesses Need to Legally Disclose Their Carbon Emissions in the UK
The pressure on companies to operate responsibly has never been higher. Customers, investors and regulators increasingly want to know how businesses are contributing to climate change. One of the key ways this is assessed is through carbon emission reporting. But is it a legal requirement in the United Kingdom for businesses to disclose their emissions
The short answer
Yes for many organisations. The scope of who must report and how they must do it depends on business size and structure. Understanding the rules is an important first step toward compliance and demonstrates commitment to sustainability.
Who is legally required to report emissions
Several regulations are already in place that require certain businesses to record and disclose their greenhouse gas emissions.
Streamlined Energy and Carbon Reporting SECR
Large companies and limited liability partnerships must report on their energy use and emissions within their annual accounts. To qualify as large a business must meet at least two of the following criteria
- More than fifty million pounds annual turnover
- A balance sheet of more than twenty five point nine million pounds
- Two hundred and fifty or more employees
These organisations must disclose their energy use, UK greenhouse gas emissions and the actions taken to improve energy efficiency.
Quoted companies
Companies listed on the London Stock Exchange or similar regulated markets have legal responsibilities to report global emissions from their operations. This requirement has been in place for more than a decade and forms part of their annual financial reporting obligations.
Public sector bodies
Government departments and certain public organisations must also report emissions under various carbon reduction schemes.
Why carbon reporting matters even if it is not mandatory for your business
If your company does not meet the legal thresholds today there are still strong reasons to measure and disclose emissions voluntarily.
- Customers expect transparency
Many consumers choose suppliers based on environmental values. Publishing emissions data shows that your business is taking responsibility. - Cost savings
Tracking emissions often reveals where energy is being wasted. Reducing energy consumption lowers carbon output and saves money. - Competitive advantage
Large organisations prefer to work with suppliers that can demonstrate sustainability credentials. Having emissions reporting already in place can help your business win bids and secure contracts. - Preparedness for future regulation
The UK government has set ambitious climate goals and requirements for disclosure are likely to expand. Businesses that already track emissions will be ready for any future changes.
