What is Operational Carbon?
Carbon emissions from the energy used to operate a building, including heating, cooling, lighting, and appliances. Operational carbon can be reduced through energy efficiency and renewable energy.
Why it matters
Building regulations are driving down operational carbon through improved energy performance standards. For commercial property owners, lower operational carbon means lower energy costs and higher EPC ratings, which increasingly affect rental values and occupier demand.
Example
A commercial landlord installs a building management system across a 10,000 sqm office block, reducing heating and cooling energy by 25%. Operational carbon drops from 180 to 135 tCO₂e per year, and the EPC rating improves from D to B.
Related terms
Whole Life Carbon
The total carbon emissions from a building over its entire life cycle, including materials, construction, operation, maintenance, and demolition. Whole life carbon assessments are increasingly required for major developments.
Scope 2 Emissions
Indirect greenhouse gas emissions from the generation of purchased energy consumed by an organisation. This includes electricity, steam, heating, and cooling purchased from utility providers. Scope 2 can be calculated using location-based or market-based methods.
