DitchCarbon vs Normative: A Comparison for Scope 3 Teams

DitchCarbon vs. Normative: Which is Right for Your Scope 3 Programme?

Choosing a platform to manage your Scope 3 emissions is a critical decision. You need a solution that not only provides accurate calculations for reporting but also empowers your team to make tangible reductions. Two prominent names in the space are DitchCarbon and Normative, but they approach the challenge from different starting points and with different core strengths.

Normative provides a comprehensive carbon accounting engine, excellent for establishing a broad, spend-based baseline across all 15 Scope 3 categories. DitchCarbon focuses intensely on turning that baseline into an actionable reduction plan, with a deep specialism in supplier-specific data for Purchased Goods and Services (Category 1).

This comparison explores their differences in methodology, supplier engagement, workflow integration, and reporting outputs to help you decide which platform is the best fit for your organisation’s maturity and goals.

At a Glance: DitchCarbon vs. Normative

Data Methodology and Accuracy

The foundation of any credible Scope 3 programme is the quality of its data. How each platform calculates emissions determines the confidence you can have in your reports and the effectiveness of your reduction strategies.

Normative: The Spend-Based Engine

Normative’s core strength lies in its powerful carbon accounting engine, which excels at rapidly calculating a comprehensive footprint using spend data. By integrating with your ERP or accounting systems, it maps your expenditure against a vast database of emissions factors to provide a complete view across all 15 Scope 3 categories.

This approach is invaluable for:

• Speed to Baseline: Quickly establishing your initial carbon footprint without needing immediate supplier contact.
• Hotspot Analysis: Identifying which procurement categories contribute most to your emissions, guiding your initial focus.
• Compliance Reporting: Generating the high-level numbers needed for initial disclosures to frameworks like CDP and CSRD.

However, a spend-based model is inherently reliant on industry averages. While scientifically robust, it cannot capture the specific performance of your individual suppliers. Two suppliers providing the same service for the same price will be assigned the same emissions, even if one runs on renewable energy and the other on coal. This makes it a starting point, not the end goal for reduction.

DitchCarbon: Prioritising Verified Supplier Data

DitchCarbon is built on the principle that real decarbonisation requires moving beyond averages. The platform is designed to find, verify, and manage supplier-specific emissions data to create a single source of truth for your supply chain.

The methodology follows a clear hierarchy:

1. Primary Data First: The platform ingests and validates data directly from your suppliers, including PCFs (Product Carbon Footprints) and organisation-level disclosures.
2. Verified Secondary Data: Where primary data is unavailable, DitchCarbon uses its extensive, mapped universe of company disclosures to fill gaps with verified, high-quality data-not just industry averages.
3. Full Provenance: Every data point is tracked with its source, version, and quality score, providing an audit-ready trail that builds trust with auditors and stakeholders.

This focus on data provenance means you can confidently set reduction targets, measure progress accurately, and reward high-performing suppliers. It transforms your emissions inventory from a static report into a dynamic tool for change.

Supplier Engagement and Data Collection

Collecting primary data from hundreds or thousands of suppliers is one of the biggest challenges in Scope 3 management. The goal is to get high-quality information without creating friction or survey fatigue.

Normative's Approach to Data Collection

Normative provides tools to help you transition from spend-based to supplier-specific data. Their platform includes features for reaching out to suppliers to request information, allowing you to gradually improve the accuracy of your footprint. This is a crucial step for any organisation looking to mature its carbon management programme and is a standard feature for enterprise-grade platforms.

DitchCarbon's Scalable Engagement Model

DitchCarbon approaches supplier engagement with a philosophy of “Engage without chaos.” The platform is designed to maximise response rates while minimising the burden on both your team and your suppliers.

Key features include:

• Minimising New Asks: Before sending a single survey, DitchCarbon scans its database of public disclosures. If a supplier’s data is already available, it’s used automatically, reducing the need to ask for information they have already shared.
• Smart Surveys & Reminders: For suppliers where data is needed, the platform manages the outreach with localised, user-friendly surveys and automated reminders.
• A Centralised Supplier Portal: Suppliers get access to a portal where they can view their performance, understand your expectations, and see how they benchmark against their peers via scorecards. This turns a data request into a value exchange.

This approach results in higher response rates and better quality data, enabling you to engage the long tail of your supply chain, not just your top 50 suppliers.

Workflow Integration and Procurement Enablement

Ultimately, Scope 3 data is only useful if it drives better decisions. How a platform integrates into your existing workflows-especially procurement-is a key differentiator.

Normative: Integrating with Financial Systems

Normative’s integrations are centred on financial systems. Its ability to connect directly to ERPs is fundamental to its spend-based methodology, allowing for automated, recurring data pulls. The output is primarily for sustainability and finance teams to use in reporting and strategic planning. The workflow is built around the reporting cycle.

DitchCarbon: Decisions Before the Purchase Order

DitchCarbon is designed to embed emissions data into the procurement process itself. The goal is to give buyers the insights they need to make climate-aware decisions before a contract is signed.

This is achieved through:

• Supplier Scorecards: Simple, shareable summaries of a supplier’s emissions performance, trends, and data quality.
• Prioritised Action Lists: Clear guidance on which suppliers to engage for the biggest reduction impact.
• In-Flow Emissions Signals: The platform provides data in a format that can be used by procurement teams during sourcing events, turning carbon into a key purchasing metric alongside cost and quality.

This shifts the focus from retroactive reporting to proactive reduction, empowering the teams who control the organisation’s spending to become agents of decarbonisation.

When to Choose Which Platform

Both DitchCarbon and Normative are powerful platforms, but they serve different primary needs. The right choice depends on your organisation’s immediate priorities and long-term climate ambitions.

Choose Normative When:

• You are at the beginning of your Scope 3 journey and need to establish a comprehensive, wall-to-wall baseline quickly.
• Your immediate priority is compliance reporting for frameworks like CSRD, and a spend-based calculation is sufficient for your current needs.
• You need to understand your emissions hotspots across all 15 Scope 3 categories to inform your initial strategy.

Choose DitchCarbon When:

• You have moved beyond initial estimates and your focus is now on driving measurable reductions in your supply chain (especially Category 1).
• You need audit-ready, supplier-specific data with clear provenance to build a credible pathway to net zero.
• You want to empower your procurement team with the data they need to make emissions a factor in their sourcing decisions.
• Your goal is to build collaborative, data-driven relationships with suppliers to accelerate decarbonisation together.
