DitchCarbon vs Sweep: A Comparison for Scope 3 Teams

DitchCarbon vs. Sweep: At a Glance

Choosing a platform to manage your organisation’s Scope 3 emissions is a critical decision. The right tool can transform a complex, manual process into a strategic advantage, while the wrong one can lead to administrative overload and unreliable data. DitchCarbon and Sweep are two prominent solutions, but they are built with different philosophies and for different primary use cases.

DitchCarbon is designed with a deep focus on solving the core challenge of Scope 3 Category 1 (Purchased Goods and Services): acquiring, verifying, and acting on supplier emissions data. It aims to eliminate data chaos and embed decarbonisation into procurement. Sweep, on the other hand, provides a broader, all-in-one carbon management platform that covers all scopes and prioritises cross-functional collaboration and compliance reporting.

This comparison explores their key differences to help you decide which approach best fits your mission.

Data Accuracy and Methodology

The foundation of any credible decarbonisation plan is trustworthy data. How each platform sources, validates, and manages this data reveals its core philosophy.

DitchCarbon: A Focus on Verified, Supplier-Specific Data

DitchCarbon is built on the principle of moving beyond industry averages and spend-based estimates as quickly as possible. The platform works to create a single source of truth for supplier emissions by consolidating data from multiple sources:

• Public Disclosures: It automatically pulls and normalises data from public reports and frameworks like CDP, saving teams from manually hunting for this information.
• Direct Supplier Engagement: Through a dedicated supplier portal, it collects primary data directly from suppliers, providing them with tools to submit information and evidence.
• Data Verification: All data is subject to quality scoring and validation checks. The platform maintains full provenance, tracking the source and version of every data point to create an audit-ready trail.

This approach is designed to provide the granular, verifiable data needed not just for reporting, but for setting meaningful reduction targets and engaging suppliers in targeted initiatives.

Sweep: A Hybrid, Automation-First Approach

Sweep’s methodology is geared towards providing comprehensive coverage across all emission sources quickly. It uses a hybrid model that starts with automation and refines over time:

• Spend-Based Calculation: For initial hotspot analysis, Sweep connects to ERP and accounting systems to calculate a baseline using financial data and emissions factors. This provides a fast, top-down view of where emissions are concentrated.
• Activity Data: The platform encourages collecting activity-based data (e.g., kWh of energy, tonnes of material) from internal systems and suppliers for more accurate calculations.
• Supplier Campaigns: To gather primary data, users can launch data collection “campaigns” to request specific information from suppliers.

Sweep’s strength lies in its ability to automate the initial data gathering from a wide array of internal business systems, making it effective for organisations that need a complete picture across all scopes from day one.

Scope 3 Coverage and Supplier Engagement

While both platforms tackle Scope 3, their approaches to supplier engagement and the breadth of categories they cover differ significantly.

DitchCarbon: Deep Engagement for Purchased Goods and Services

DitchCarbon’s expertise is concentrated on Scope 3 Category 1, which often represents the largest and most complex part of an organisation’s footprint. The platform is engineered to engage suppliers at scale-from the top strategic partners to the long tail-without creating administrative chaos.

Key features include:

• A Scalable Supplier Portal: A user-friendly interface for suppliers that minimises repetitive requests and makes data submission straightforward.
• Response-Rate Boosters: Automated reminders, multilingual support, and clear guidance help improve the quality and quantity of supplier responses.
• Quality Assurance: Built-in checks ensure the data submitted is robust and fit for purpose, reducing the back-and-forth between your team and your suppliers.

The goal is to lighten the load for both your team and your suppliers, fostering a collaborative relationship focused on reduction, not just reporting.

Sweep: Broad Coverage Across All Categories

Sweep is designed to cover all 15 Scope 3 categories, making it a powerful tool for companies needing to report on a wide range of indirect emissions. This is particularly valuable for financial institutions tackling Category 15 (Financed Emissions) or businesses with significant emissions from logistics, business travel, or waste.

Its collaboration features allow different business units to take ownership of their data. For example, the finance team can manage financed emissions, while the logistics team can input data for upstream and downstream transportation. This distributed ownership model helps central sustainability teams orchestrate data collection across the entire enterprise.

Integrations and Workflow

A platform’s true value is realised when it fits seamlessly into your existing workflows and empowers teams to act.

DitchCarbon: Enabling Sustainable Procurement

DitchCarbon is designed to bridge the gap between sustainability reporting and procurement action. The workflow is built to provide buyers with a clear emissions signal before a purchase order is ever raised. By integrating with procurement systems and providing simple scorecards and benchmarks, it helps buyers compare suppliers on their climate performance alongside traditional metrics like cost and quality.

This turns the procurement team into an active driver of decarbonisation, moving sustainability from a post-hoc reporting exercise to a proactive, decision-making criterion.

Sweep: Centralising for Compliance and Reporting

Sweep’s workflow is optimised for centralisation and reporting. It integrates with a wide variety of business systems (ERPs, HR, travel management) to pull data into one place. From there, its internal collaboration tools allow tasks to be assigned, progress to be tracked, and reports to be generated for various frameworks like CSRD.

The workflow is ideal for a central sustainability or finance team tasked with orchestrating an enterprise-wide carbon accounting process, ensuring all data is collected, consolidated, and ready for disclosure.

The Verdict: When to Choose Which Platform

The choice between DitchCarbon and Sweep depends entirely on your organisation’s primary goal and most significant pain point.

Choose DitchCarbon if:

• Your main challenge is collecting accurate, verifiable data from hundreds or thousands of suppliers for Scope 3 Category 1.
• Your goal is to actively reduce supply chain emissions, not just report them.
• You want to empower your procurement team to make climate-aware decisions and integrate emissions data into the sourcing process.
• You need an audit-ready system with clear data provenance and version control for every supplier.

Choose Sweep if:

• You need an all-in-one platform to manage emissions across Scopes 1, 2, and all 15 categories of Scope 3.
• Your immediate priority is compliance reporting for frameworks like CSRD and automating data collection from internal systems.
• You have significant emissions in complex categories like financed emissions (Category 15).
• Your operating model relies on a central team coordinating data collection across many different business functions.

Ultimately, DitchCarbon offers a deep, specialised solution for mastering supplier decarbonisation, turning data into action. Sweep provides a broad, comprehensive platform for managing enterprise-wide carbon accounting and compliance.
