6 Best SBTi software for reaching your science-based targets

Why SBTi software matters

Setting a science-based target is the easy part. The SBTi commitment you listed on your website will take a few months to formalise. What comes after it is what most companies are not ready for. This includes collecting credible Scope 1, 2, and 3 data, building a reduction roadmap, and defending your progress to auditors and investors.

The problem is rarely commitment. Sustainability managers across the Nordic region and the EU tell us the same things: Scope 3 is a black box, leadership asks questions they can’t answer, and their current tools (usually spreadsheets and email threads) break the moment complexity increases.

SBTi software provides the infrastructure to measure, manage, and reduce emissions in line with your targets. But most tools stop at measurement. The best ones go further and help you act on what you find.

Why trust us?

At Emission Twin, we work with sustainability managers, CFOs, and leadership teams who are managing exactly this challenge. The tools in this guide are ones our clients have evaluated, tested alongside us, or switched from before finding a platform that matched the full complexity of their SBTi programme. We assessed each tool against the criteria that matter most.

How we evaluated these tools

We assessed every platform in this guide against the same criteria:

• Framework alignment: How well the platform supports structured disclosure under GHG Protocol and SBTi requirements.
• Scope 3 depth: Whether the platform handles all relevant GHG Protocol categories or focuses on a subset, and how it supports supplier-level primary data collection.
• Reduction planning: Whether the platform helps you model and prioritise reduction strategies, not just measure current performance.
• Auditability: Whether every figure is traceable from raw input to final number, with methodology documentation and version history.
• Onboarding speed: How quickly teams can move from signup to live emissions data without lengthy implementation projects or consulting dependency.

1. Emission Twin

Best for: Nordic companies that need to hit SBTi targets, not just report against them

Emission Twin is a climate management platform built for companies with real Scope 3 complexity and SBTi targets that require more than a spreadsheet to hit. It uses digital twin technology to create a virtual model of your operations and value chain. 

The advantage of Emission Twin is that it enables you to measure emissions, test reduction strategies, and make climate decisions based on real business data.

The core of the platform is Emission Control, a module that handles data collection and reporting across all GHG Scopes. Auto-suggested emission factors, built-in validation, version history, and year-on-year comparisons come standard. 

Additionally, every calculation is traceable from raw input to the final number. When auditors or leadership ask how a figure was reached, the answer is already documented.

Onboarding is fast. The team supports customers in Swedish and English, and technical onboarding takes around three hours. Pricing is transparent with no hidden fees.

Key features

• Emission Control structures Scope 1, 2, and 3 data collection with auto-suggested emission factors, full source documentation, and a complete version history behind every figure
• Reduction Roadmap lets you model SBTi-aligned reduction strategies side by side, compare projected emissions impact, and link actions to specific supplier or procurement decisions
• Analyse module builds custom dashboards to track emissions, monitor SBTi progress, and export data for reports and internal decision-making
• Product Carbon Footprint (PCF) is an upcoming feature that combines corporate carbon accounting and product-level calculations in one platform

Pros

• Scenario modelling tied to real business inputs, not abstract assumptions
• Fully traceable data with version history and emission factor transparency
• Built for auditability, with support for internal teams and external climate consultants
• Same-day onboarding with personal support in Swedish or English

Cons

• Less contextual support for companies primarily based outside the Nordic and EU regions
• Contact sales for pricing

2. Normative

Best for: Companies building their first structured Scope 3 baseline

Normative is a carbon accounting platform with a strong reputation for Scope 3 automation. It pulls in spend data and maps it to emissions using one of the largest available emission factor databases, making it faster to get a full Scope 3 picture than most manual approaches.

For companies at the start of their SBTi journey, Normative offers a low-barrier entry point to establishing a credible baseline. It aligns well with GHG Protocol methodology and is accessible for sustainability teams without deep technical resources.

Key features

• GHG Protocol-based Scope 3 accounting provides a recognised methodology across all relevant categories
• Emissions factor database reduces time spent manually sourcing calculation factors
• Carbon footprint reporting produces structured output suitable for disclosure, internal review, and target-setting

Pros

• Strong GHG Protocol alignment gives companies a credible foundation for their first SBTi baseline
• Low technical barrier makes it accessible for teams without specialist carbon accounting expertise
• Fast to get initial Scope 3 data structured

Cons

• No reduction planning or scenario modelling; companies with active SBTi targets will need additional tools
• Supplier engagement for primary data collection is limited, so Scope 3 accuracy can rely heavily on spend-based estimates

3. Climatiq

Best for: Companies that want SBTi-compliant emissions calculations embedded in their existing systems

Climatiq is a carbon intelligence platform built around an API-first architecture. Rather than logging into another dashboard, it brings SBTi-aligned emissions calculations directly into the tools and workflows you already use. Every figure includes a full audit trail that includes the applied emission factor, data source, and year of validity. 

Climatiq is not a standalone sustainability management platform and lacks a reduction roadmap or supplier engagement tools, but it offers precise, SBTi-aligned calculation infrastructure that integrates with whatever system your team already uses.

Key features

• Audit-ready calculation trail with applied emission factor, data source, year valid, and full methodology documentation for every figure
• AI-powered Autopilot automates Scope 3 emissions calculations across 16+ sectors and 300+ regions via a single API
• Emissions factors vetted by an in-house team of climate scientists and overseen by a Scientific Advisory Board, and updated on a regular basis

Pros

• SBTi-aligned calculations with a full audit trail built into every API response
• Reduces the need to rebuild or manually maintain emissions calculation logic

Cons

• No built-in reduction planning or SBTi target-tracking features
• Requires technical resources to implement; not suited to teams without API integration capability

4. Sweep

Best for: Mid-market companies managing Scope 3 supplier data at scale

Sweep is a carbon management platform that replaces email-based supplier data collection with structured workflows inside the platform. It handles Scope 1, 2, and 3 tracking, supports common reporting frameworks, and is accessible for mid-market sustainability teams without deep technical resources.

For SBTi purposes, Sweep covers core data collection and target progress tracking well. It does not offer reduction scenario modelling, so teams that need to test climate strategies before committing resources will need to look elsewhere.

Key features

• Supplier engagement tools allow structured outreach, primary data collection, and response tracking without email threads
• Scope 1, 2, and 3 tracking centralises emissions data across the full carbon footprint
• Target progress tracking shows how current emissions trends compare to SBTi goals over time

Pros

• Accessible interface suits sustainability teams managing Scope 3 data without dedicated technical support
• Good analytics and progress tracking features keep SBTi targets visible across the organisation

Cons

• No reduction scenario modelling
• Less suited to organisations with complex workflows or advanced regulatory reporting requirements

5. Plan A

Best for: EU SMEs taking their first serious step into SBTi

Plan A is a sustainability platform designed for European mid-market companies. It covers Scope 1, 2, and 3 emissions alongside broader ESG reporting, the GHG Protocol, and other frameworks. The platform comes with a clean interface that suits teams without large technical resources.

For companies that haven’t yet formalised their climate data processes, Plan A offers a lower-friction entry point than most enterprise tools. Pricing is more accessible than the platforms above it on this list, which matters for companies building their SBTi programme from scratch. For core Scope 1–3 tracking and SBTi framework alignment, it covers the essentials.

Key features

• Scope 3 carbon accounting structured around GHG Protocol methodology across all relevant categories
• Supports EU regulatory disclosure requirements
• Reduction tracking lets companies set targets, monitor progress, and track the impact of reduction initiatives over time

Pros

• Strong EU context makes it relevant for companies operating under European frameworks
• Accessible pricing and fast onboarding suit SMEs entering SBTi for the first time
• Clean interface and structured workflows suit small sustainability teams

Cons

• Scenario modelling is limited compared to more specialised platforms
• Supplier engagement for primary data collection is not a core strength
