Scope 1 — Direct Emissions (tCO₂e)
Combustion in owned/controlled sources, process emissions, company vehicles, fugitive emissions.
Stationary Combustion
Mobile Combustion
Process Emissions
Fugitive Emissions
Scope 2 — Indirect Energy Emissions (tCO₂e)
Purchased electricity, steam, heat, cooling. Use market-based if available, otherwise location-based.
Purchased Electricity
Market-based Electricity
Heat & Steam
Scope 3 — Value Chain Emissions (tCO₂e)
All other indirect emissions. If Scope 3 ≥ 40% of total, SBTi requires a Scope 3 target.
Purchased Goods & Services (Cat 1)
Business Travel & Employee Commuting (Cat 6/7)
Use of Sold Products (Cat 11)
Other Scope 3 Categories
Scope 1 & 2 Near-Term Target
SBTi requires ≥42% absolute reduction by 2030 from 2019 base year for 1.5°C alignment. Must cover ≥95% of Scope 1+2.

⚠️ This tool provides a preliminary pathway model for planning purposes. Official SBTi target setting requires submission to the SBTi Target Validation Team at sciencebasedtargets.org. All targets must be validated per SBTi criteria before public commitment. Consult sbti.org/companies/ for sector-specific pathways and SBTI FLAG criteria for land-based industries.
Understand the rules behind your pathway
This modeler uses the 4.2% a year linear pathway from SBTi Corporate Net-Zero Standard V1.3.1, which is open for submissions until 31 January 2028. Version 2.0 takes effect on 31 January 2027 and changes the Scope 3 and target-structure rules.
