Measure
Baseline emissions are a record of the greenhouse gases that have been produced in the past and are the reference point against which emission reductions can be measured.
Aims and targets
Targets allow you to judge whether the plans you made to reduce your carbon emissions are working, and whether the reductions achieved are meaningful.
Reduce
Select best carbon reduction projects for you and your business, based on your values, the cost, and likely payback time.
Track
Track your carbon emissions to reflect the changes and compare how well you are doing against the targets.
Offset
Offset schemes work by paying volunteers, companies or charities to do things which ‘negate’ your carbon emissions, for example, planting trees.
Certify
Certification is a valuable process that provides checks and balances for the sector.

If your company is classed as “large” in accordance with the Companies Act 2006 you will need to carry out ESOS compliance and provide a report by the stated deadline (next deadline, for Phase 4, is the 5th December 2027).
Any organisation meeting any of the following criteria MUST comply with ESOS:
- Have over 250 members of staff.
- Or turnover of over 50 million Euros (£43 million) and an annual balance sheet total in excess of 43 million euro (£37 million).

Frequently asked questions – ESOS and EAPs
When do I need to submit my ESOS report?
The deadline for ESOS Phase 3 compliance was 5th August 2024. If you didn’t submit your report and you are required to do it now, please call us ASAP. Our in-house ESOS Lead Assessor can help you.
The deadline for ESOS Phase 4 compliance is 5th December 2027.
What happens if I don't comply with ESOS?
If you don’t comply with ESOS you will be at risk of being fined. You will be charged a fixed penalty of £5,000 plus an additional £500 per day until you submit your ESOS report. As ESOS is a public report, not complying with it could also damage your reputation.
Will ESOS Phase 4 include more information?
It is expected that you will need to include more information about your carbon emissions on ESOS Phase 4 (e.g. a wider analysis of your Carbon Footprint, a Carbon Reduction Plan, and Net Zero assessments).
Do I need an ESOS Lead Assessor?
Yes, to legally comply with ESOS you need a qualified ESOS Lead Assessor to sign your report.
What happens if I don't have all the data for ESOS?
It can be complicated to get all the data required for ESOS, but it is a legal requirement that you get it. Here’re some things you can try:
- Checking with finance teams for invoices.
- Contacting the utility provider for usage details or online portal access.
- Requesting an FTP data download if necessary.
