Scope 1 Emissions

Direct emissions from sources your organisation owns or controls

What is Scope 1 Emissions?

Scope 1 emissions are direct greenhouse gas (GHG) emissions that occur from sources that are owned or controlled by an organisation. This includes emissions from combustion in owned or controlled boilers, furnaces, vehicles, and emissions from chemical production in owned or controlled process equipment.

Why It Matters for SECR

Scope 1 emissions are mandatory to report under SECR for qualifying companies. They represent your most direct environmental impact and often indicate significant energy costs.

Examples

  • 1

    Natural gas burned in your building's boiler

  • 2

    Diesel fuel used in your company-owned delivery vans

  • 3

    Refrigerant leaks from your air conditioning units

  • 4

    Fuel oil used in backup generators

SECR Reporting Requirements

SECR requires all Scope 1 emissions to be reported in tonnes of CO2 equivalent (CO2e), using UK Government conversion factors.
