International Institute for Sustainable Development Response to DESNZ Consultation on Scope 3 Emissions Guidance

The IISD response to the DESNZ consultation argues that updated EIA guidance for fossil fuel projects should require the separate reporting of Scope 3, Category 11 emissions and the use of zero-emission baselines for new projects. It further recommends that the significance of emissions be assessed against science-based 1.5°C scenarios and the specific need for the project.

• The IISD recommends that the updated guidance specify that the significance of emissions be assessed based on the project's need and other existing fields, aligned with science-based 1.5°C scenarios.
• The IISD proposes that Scope 3, Category 11 emissions, which refer to the emissions from the ultimate consumption of oil, must be reported as a separate category.
• The IISD suggests that the baseline for assessing emissions should generally be zero for new projects, as no emissions exist without the project, unless the EIA concerns the adaptation of an existing extraction facility.
