# Scope 1 emissions

*ESG · Global*

## Short definition

Direct emissions from sources owned or controlled by the entity.

## Full definition

On-site combustion, owned-fleet vehicles, refrigerants. For an office building: gas heating and on-site generators. The first emissions to attack in any net-zero plan because they sit on the landlord's own balance sheet.

## Why this matters for Class A leasing

Scope 1 emissions is part of the esg vocabulary that institutional [Class A](/glossary/class-a) occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
