Sweep Review (2026): SECR & UK SRS Fit

What Sweep is

Sweep is a collaborative carbon and ESG platform founded in France in 2020, with offices in London and Denver. The platform specializes in supplier engagement and value-chain data collection, offering an "upload once, use across all frameworks" approach to multi-framework reporting. See how Sweep compares to other carbon reporting software for UK companies.

The platform focuses on solving the supplier engagement challenge that makes Scope 3 reporting difficult for organizations with complex supply chains. Sweep's collaborative approach helps companies collect real-time supplier data rather than relying purely on spend-based estimates.

Who it's for

Sweep targets organizations managing complex multi-tier supply-chain emissions across multiple reporting frameworks. The platform suits companies that need strong supplier engagement capabilities and those reporting across CSRD, ISSB, PCAF and other frameworks simultaneously.

Companies publicly listed on Sweep's website include L'Oréal, SSE, Lacoste, Bouygues and Swisscom, indicating strength in consumer goods, utilities and telecommunications. The platform works best for organizations prioritizing value-chain collaboration over pure carbon accounting depth.

Scope 1, 2 & 3 coverage

Sweep covers all three GHG Protocol scopes with particular strength in Scope 3 value-chain data through real-time supplier engagement. The platform handles all 15 Scope 3 categories with emphasis on collecting activity-based data from suppliers rather than relying on spend-based estimates.

For Scope 3, the collaborative approach helps companies move from estimates to actuals by engaging suppliers directly in the data collection process. This supplier engagement capability addresses one of the biggest challenges in Scope 3 reporting accuracy and audit readiness.

UK frameworks support

The platform supports GHG Protocol, CSRD, ISSB, PCAF, GRI, SFDR, SASB and CDP frameworks with the "upload once, use across all frameworks" approach. While not specifically built for UK regulations, the ISSB support means outputs should be compatible with UK SRS requirements.

The London office provides UK market support, though the platform's European heritage means CSRD receives more focus than UK-specific requirements like SECR optimization. For companies with both UK and EU reporting obligations, this multi-framework approach can be advantageous.

Assurance readiness

Sweep emphasizes strong governance and validation features, with comprehensive audit trails maintained through the supplier engagement process. The collaborative approach to data collection can actually strengthen assurance readiness by providing activity-based rather than estimated data.

For UK SRS S2 assurance requirements, the emphasis on data governance and supplier engagement aligns well with assurance expectations for Scope 3 verification. The platform's collaborative approach helps build the documentation trail that third-party assurance requires.

Pricing

Sweep offers enterprise and mid-market pricing tiers available on application. The collaborative features and multi-framework coverage reflect mid-market to enterprise positioning, though likely more accessible than pure enterprise platforms given the mid-market tier.

The pricing approach suits organizations that can justify the investment in supplier engagement and multi-framework capabilities, though may exceed budgets for companies needing basic carbon accounting without collaboration features.

Alternatives to Sweep

For companies considering alternatives to Sweep, key options include:

• Plan A — Science-led decarbonisation platform with independently certified methodology
• Greenly — AI-assisted platform with broader ESG coverage but less supplier engagement focus
• Climatise — UK-first platform for companies prioritising SECR and UK SRS over multi-framework breadth

The choice often depends on whether supplier engagement and multi-framework efficiency justify the complexity versus simpler platforms focused on single-market requirements. Companies comparing carbon reporting software should weigh collaboration benefits against UK regulatory specialisation.

Verdict

Sweep's strength lies in collaborative supplier engagement and multi-framework efficiency for organizations with complex value chains. The "upload once, use across all frameworks" approach addresses a real pain point for companies reporting across multiple jurisdictions.

For organizations managing complex multi-tier supply chains and needing strong supplier engagement capabilities, Sweep provides valuable collaboration features. The London office ensures UK support, though the platform's multi-framework rather than UK-specific focus may matter for regulatory alignment.

However, companies seeking UK regulatory focus or those without complex supplier engagement needs may find simpler, more focused alternatives better suited to their requirements. Sweep works best where collaboration efficiency and multi-framework capability justify the additional complexity.
