In accordance with the SBTi Corporate Net-Zero Standard, companies identify emissions-intensive activities (EIAs) within their value chains, quantify and report associated emissions, and assess progress against the relevant requirements to ensure these emissions sources are properly accounted for and mitigated.82 By prioritizing action on these activities, companies can focus their influence on the most significant drivers of global GHG emissions and support systemic decarbonization toward a net-zero economy.
Table A.1 defines the scope 3 EIAs referenced throughout the Corporate Net-Zero Standard and identifies each activity using its corresponding NACE code classification. These activities have been selected because they represent sectors with significant emissions impact and are critical to the global net-zero transition. The list of EIAs may expand over time as SBTi sector guidance and pathways continue to develop.
The emissions boundary for each activity is defined according to the nature of the activity to ensure consistent and comprehensive accounting of the most relevant lifecycle stages.
