Intensity Ratio
A metric that normalises emissions against a business activity measure
What is Intensity Ratio?
An intensity ratio expresses greenhouse gas emissions per unit of activity. It allows comparison over time as a company grows or shrinks, and enables benchmarking against other organisations. Common denominators include revenue, employee numbers, floor area, or production output.
Why It Matters for SECR
SECR requires at least one intensity ratio to be reported alongside absolute emissions. This helps stakeholders understand whether emissions are growing because the business is growing, or because efficiency is declining.
Examples
- 1
tonnes CO2e per £ million turnover
- 2
kg CO2e per employee
- 3
kg CO2e per m² of floor space
- 4
kg CO2e per unit produced
SECR Reporting Requirements
At least one intensity ratio must be disclosed in your SECR report. It should use a denominator that is relevant to your business and allows meaningful comparison.
