Air Emissions Guidelines

The existing requirements have been renamed to align with StZ V2, the PTE-VOC calculation methodology has been expanded with a complete calculation formula, the Scope 1 and Scope 2 GHG emissions guidance has been updated to clarify the required activity data (including fugitive emissions), and the previously marked "coming soon" requirement for setting Paris Agreement-aligned GHG reduction targets has now been published.

Placeholder GHG target requirement published

The previously marked "coming soon" requirement has been published. New guidance has been introduced for setting Paris Agreement-aligned GHG reduction targets, including baseline year selection, target year requirements, annual emissions reduction tracking, and implementation guidance for suppliers with and without existing SBTi-validated targets.

The requirement wording has been updated

Previous requirements:

1. Calculate the Potential to Emit (PTE) of Volatile Organic Compounds (VOCs)
2. Calculate and report annual Scope 1 & Scope 2 GHG emissions

Updated requirements:

1. Potential to Emit (PTE) - Volatile Organic Compound (VOC) emissions are measured and reduced over time
2. Scope 1 and 2 greenhouse gas (GHG) emissions are measured and reduced over time
3. Set Paris Agreement aligned targets to reduce GHG emissions against the baseline year

Expanded PTE-VOC calculation formula

The PTE-VOC calculation has been updated from a simplified calculation description to a complete mathematical formula. The updated section includes the full equation, definitions for all variables used in the calculation, and specifies the output unit as kg VOC/year.

Expanded Scope 1 & 2 GHG activity data

The guidance has been updated to clarify and expand the activity data required to calculate Scope 1 and Scope 2 GHG emissions. The updated guidance now explicitly includes purchased and on-site-generated electricity, heating, cooling and steam, facility-owned or controlled vehicle fuel consumption, and fugitive emissions from refrigeration, air-conditioning, and fire-suppression equipment.
