Floodlight vs Persefoni
Enterprise carbon accounting and climate disclosure platform widely used by financial institutions for PCAF financed-emissions reporting and regulatory disclosure.
Satellite-verified emissions data
Emissions figures derived from independent atmospheric satellite observations, not reported disclosures or emissions factors.
Persefoni is entirely activity-data and emissions-factor based. No satellite measurement layer.
Asset-level monitoring
Emissions and risk scores tied to individual facilities, buildings, or assets - not rolled-up sector or company averages.
Persefoni supports facility-level uploads but depends on self-reported data, not independent measurement.
Independent third-party verification
Data produced without reliance on issuer self-disclosure; independently reproducible and auditable by third parties.
Persefoni figures derive from issuer-supplied activity data - they cannot be independently verified at source.
Continuous / near-real-time monitoring
Emissions tracked on an ongoing basis with alerts for anomalies; not a once-a-year snapshot.
Persefoni is a periodic-reporting tool; no continuous monitoring or anomaly detection.
Global asset coverage (190+ countries)
Coverage of industrial and commercial assets worldwide, not limited to North America or Western Europe.
Scope 1 direct emissions
Direct emissions from owned or controlled sources including combustion, process emissions, and fugitive releases.
Scope 2 market and location-based
Indirect emissions from purchased electricity, steam, and cooling - both market-based and location-based methods.
Scope 3 / PCAF financed emissions
Financed emissions across lending and investment portfolios aligned with PCAF data quality scores 1-3.
Both support PCAF. Floodlight uses satellite-verified data for PCAF score 1; Persefoni relies on self-disclosed activity data typically scoring 3-5.
Methane and fugitive emissions detection
Detection of methane leaks, venting, and flaring events often missed by factor-based inventories.
Persefoni cannot detect unreported fugitive or flaring events.
Multi-gas coverage (CO2, CH4, N2O, HFCs)
Coverage beyond CO2 to include the full basket of Kyoto greenhouse gases on a CO2e basis.
CBAM embedded emissions reporting
Facility-level embedded emissions per CN code for EU Carbon Border Adjustment Mechanism importer reporting.
Persefoni has no CBAM-specific embedded-emissions workflow.
Physical climate risk assessment
Asset-level exposure scores for flood, heat stress, wildfire, sea-level rise, water stress, hurricane, and other perils.
Persefoni is a carbon accounting tool; no physical climate risk capability.
Transition risk assessment
Exposure to regulatory carbon costs, stranded-asset risk, and technology disruption under decarbonisation scenarios.
Persefoni supports decarbonisation pathway planning but does not model transition VaR.
Climate Value-at-Risk (Climate VaR)
Probabilistic financial loss estimate under named climate scenarios, in the same units as market and credit VaR.
NGFS Phase V scenario alignment
Stress-testing across all six NGFS Phase V reference pathways (Net Zero 2050, Below 2C, Delayed Transition, etc.).
CSRD / ESRS E1 compliance
Data mapped to CSRD ESRS E1 data-point IDs including E1-5, E1-6, and E1-9 financial-effects table.
SFDR / Principal Adverse Impact (PAI)
PAI indicators for Article 8 and 9 funds including GHG intensity, biodiversity, water, and social metrics.
Full audit trail and data provenance
Every figure traceable to satellite overpass, model version, and confidence band - reproducible by external reviewers.
Persefoni provides a data audit trail but it traces back to user inputs, not independent measurement.
Limited assurance (ISAE 3410)
Methodology and documentation pack sufficient for limited assurance opinion without supplementary procedures.
REST API access
Programmatic access to all data via documented REST API with pre-trade and portfolio query modes.
Honest verdict
Where Floodlight wins
Floodlight measures emissions directly from satellite observations rather than calculating them from activity data and emissions factors. This matters for financial institutions because satellite-verified figures are independently reproducible - they cannot be gamed by the disclosing company, they catch fugitive and flaring events that factor-based methods miss, and they satisfy the increasing demand from auditors and regulators for evidence-grade data. Floodlight also covers physical and transition climate risk in a single platform, and provides CBAM-ready embedded emissions data that Persefoni does not support.
Where Persefoni wins
Persefoni has deep workflows for Scope 3 category management, including supply-chain engagement tools and a large library of activity-based emissions factors. For corporates building an internal carbon accounting programme from the ground up - where self-reported activity data is the primary input - Persefoni is a mature, well-supported platform. It also has stronger employee-level and operational-emissions workflows for mid-market corporates.
