Residual Emissions

Definitions

Option 1

Residual Emissions means the Greenhouse Gas (GHG) Emissions, measured in Carbon Dioxide Equivalent, that are emitted after all reasonable efforts have been made by [organisation name] to reduce GHG Emissions from all operations [including value and supply chains].

Option 2

Residual Emissions are any GHG Emissions which remain after a project or organisation has implemented all technically and economically feasible opportunities, as determined by a Climate Professional as part of a Carbon Footprint assessment, to reduce emissions in all scopes and from all sources.

Drafting notes

The words “all operations” and “all scopes” are intended to refer to Scope 1, 2 and 3 Emissions.  If the clause being drafted is intended to refer only to one or two of these categories of emissions then this definition will need to be amended. 

In order to achieve Net Zero Targets, it is essential first to calculate the extent of Residual Emissions in order to come up with a comprehensive plan for balancing them out. Emissions should be reduced to the greatest possible extent before any Residual Emissions can be compensated using Carbon Offsetting.

Emissions trajectories to net zero and an estimate of Residual Emissions should be regularly updated and maintained. The trajectory that will be appropriate will depend on the sector[s], level of ambition and available investment for the relevant entities, and is likely to be the result of advice from a Climate Professional as part of a Carbon Footprint assessment.

Application

National climate laws, local planning authorities, construction contracts, contract manufacturing clauses, corporate climate policies, supply chain agreements, employment contracts.

Used in the following TCLP model clauses:

Scarlett’s Performance Conditions (Environmental, Social and Governance (ESG) based performance conditions for employee incentive awards)

Felix’s Clause (Net Zero Completion Adjustment clause)

Tristan’s Clause (Construction Materials: Green Procurement)

Francis’s Clause (Climate-Aligned Construction Waste Management)

Evelyn & Ezra’s Clause (Securing Net Zero in Planning Development Projects)
