Sector, base year emissions, and timeline in; a reduction pathway aligned with 1.5°C or well-below 2°C out. Generic target-setting tooling — independent of the official Science Based Targets initiative, using its published rates rather than guesswork.
Supply chain emissions measurement and reduction across the full electronics lifecycle.
Mining impact and ecosystem accountability — from rare earth extraction to habitat loss.
eWaste, hazardous materials, and the circular economy — keeping electronics out of landfill.
Your supply chain is a graph, not a spreadsheet.
Three pressures converge on the same answer, whichever framework you set it under.
The absolute contraction approach: a linear annual reduction from your base year. All calculation runs in your browser.
SBT Tools is independent tooling, not affiliated with or endorsed by the Science Based Targets initiative. The rates below follow the published absolute-contraction method; formal validation happens with the SBTi directly, and the official framework adapted for electricals and electronics lives at sbti.tools.
Your sector determines which pathway applies: power, cement, steel and a few others have sector-specific decarbonisation pathways, and every sector can use absolute contraction. If your company spans several, pick the one with the largest share of revenue or emissions.
The reference point your reduction is measured from. Choose a year with reliable, auditable data; avoid anomalous years such as COVID-affected 2020.
Near-term targets run 5–10 years from submission and are mandatory for SBTi validation; long-term and net-zero targets extend to 2050 or earlier.
Since July 2024, near-term Scope 1 & 2 targets under the SBTi must be 1.5°C aligned: at minimum a 4.2% year-over-year absolute reduction.
Direct emissions from owned or controlled sources.
Indirect emissions from purchased electricity, heat, or steam.
Value chain emissions. A Scope 3 target is required when they reach 40% of the total; the screener below helps estimate them.
Two published routes to the same destination. Which one fits depends on your sector and how fast you are growing.
A fixed percentage reduction in total emissions regardless of business growth. The default method for most sectors, and the only method accepted for Scope 1 & 2 near-term targets under the SBTi since 2024. Simple to calculate and communicate, and it guarantees an absolute decrease — though it does not account for production growth, can penalize fast-growing companies, and may incentivize outsourcing over decarbonisation.
The Sectoral Decarbonization Approach allocates a sector's carbon budget by projected activity growth: companies reduce emissions per unit of output — tCO2e per tonne of steel, say — along a sector-specific pathway built on IEA data. Fair to high-growth companies in carbon-intensive sectors and scientifically precise, but available only for homogeneous sectors, more complex to verify, and not available for Scope 3 targets.
| Criterion | Absolute contraction (ACA) | Sectoral decarbonisation (SDA) |
|---|---|---|
| Principle | Fixed percentage cut in total emissions | Emissions per unit of output along a sector pathway |
| Minimum rate | 4.2%/yr (1.5°C) or 2.5%/yr (well-below 2°C) | Sector-specific, from IEA pathway data |
| Sectors | All sectors, all scopes | Power, cement, steel, aluminum, pulp & paper, transport |
| Scope coverage | Required for Scope 1 & 2 near-term targets since 2024 | Not available for Scope 3 targets |
| Growth | Ignores production growth | Accounts for projected activity growth |
| Effort | Simple to calculate and communicate | More complex to calculate and verify |
Enter estimated emissions for each GHG Protocol Scope 3 category. Categories above 5% of your Scope 3 footprint are material and belong inside your target boundary; the SBTi requires coverage of at least 67% of total Scope 3 emissions.

Materiality threshold: 5% of total Scope 3 emissions. Coverage requirement: your target must cover at least 0 tCO2e (67% of total Scope 3) to meet SBTi criteria.
