Persefoni Review (2026): SECR & UK SRS Fit

What Persefoni is

Persefoni is a Tempe, Arizona-based carbon management platform founded in 2020, with offices including the UK. Recognized as a Forrester Wave leader, the platform specializes in assurance-grade regulatory disclosure and financed emissions (PCAF) for financial institutions. See how Persefoni compares to other carbon reporting software for UK companies.

The platform features an AI Copilot and is designed specifically for organizations under regulatory and assurance pressure. Persefoni's focus on financed emissions analytics makes it particularly suited to financial institutions needing to measure and report portfolio-level emissions alongside operational emissions.

Who it's for

Persefoni targets financial institutions and large corporates under regulatory and assurance pressure, particularly those needing financed emissions capabilities. The platform suits organizations requiring enterprise-grade assurance readiness and regulatory compliance across multiple frameworks.

Companies publicly listed on Persefoni's website include Xerox, Snowflake, Under Armour and Aramark, indicating capability across technology, retail and services sectors. The platform works best for enterprises that prioritize regulatory compliance and assurance readiness over cost accessibility.

Scope 1, 2 & 3 coverage

Persefoni covers all three GHG Protocol scopes plus financed emissions (PCAF) for financial institutions. The platform handles both spend-based estimates and activity-based actuals, with particular strength in the financial services requirements that other platforms may not address.

For Scope 3, Persefoni handles all 15 categories with emphasis on data quality and assurance readiness. The financed emissions analytics provide portfolio-level insights that are essential for banks, asset managers and other financial institutions reporting under frameworks like PCAF and TCFD.

UK frameworks support

The platform supports SBTi, TCFD, CSRD, PCAF, SASB, California disclosure and ISSB-aligned frameworks. While the platform has US regulatory heritage, the ISSB alignment means outputs should be compatible with UK SRS requirements, though with less UK-specific optimization than dedicated UK platforms.

The UK office provides local support and expertise for UK regulatory requirements, though the platform's design centre focuses on global financial services regulation rather than UK corporate reporting nuances like SECR optimization.

Assurance readiness

Persefoni is specifically designed for assurance readiness, with comprehensive audit trails, methodology documentation and data governance features. The platform's focus on regulatory disclosure means assurance requirements are built into the core architecture rather than added as an afterthought.

For UK SRS S2 assurance requirements, the enterprise-grade approach to documentation and the Forrester recognition provide confidence in meeting assurance expectations. The AI Copilot also helps users understand and document their methodology choices for assurance review.

Pricing

Persefoni offers PRO and ADVANCED plans available on application, reflecting enterprise-focused pricing for organizations with substantial regulatory compliance budgets. The assurance-grade capabilities and financed emissions analytics justify premium positioning.

The enterprise approach suits large organizations and financial institutions requiring comprehensive regulatory compliance capabilities but makes the platform less accessible for smaller companies or those with limited sustainability resources.

Alternatives to Persefoni

For companies considering alternatives to Persefoni, key options include:

• Watershed — Enterprise platform with scenario modelling, though without financed emissions specialization
• Normative — TÜV SÜD validated platform with independent verification but less financial services focus
• Climatise — UK-first platform for companies prioritising SECR and UK SRS over global regulatory breadth

The choice often depends on whether financed emissions capabilities and Forrester recognition justify the premium versus alternatives focused on corporate rather than financial services requirements. Companies comparing carbon reporting software should consider whether Persefoni's financial services heritage matches their reporting needs.

Verdict

Persefoni's strength lies in assurance-grade regulatory disclosure and financed emissions capabilities for financial institutions and large corporates under regulatory pressure. The Forrester Wave leadership and enterprise customer base demonstrate proven capability in complex regulatory environments.

For financial institutions needing PCAF-compliant financed emissions reporting, or large corporates requiring enterprise-grade assurance readiness, Persefoni provides comprehensive capabilities. The AI Copilot and UK office support add value for complex regulatory requirements.

However, companies without financed emissions requirements or those seeking UK-specific regulatory focus may find better value in platforms designed around corporate rather than financial services needs. Persefoni works best where regulatory complexity and assurance readiness justify the premium positioning.
