Data Foundation
Feature
Floodlight
Sweep

Satellite-verified emissions data

Emissions figures derived from independent atmospheric satellite observations, not reported disclosures or emissions factors.

Asset-level monitoring

Emissions and risk scores tied to individual facilities, buildings, or assets - not rolled-up sector or company averages.

Sweep supports facility-level data entry but not independent satellite observation.

Independent third-party verification

Data produced without reliance on issuer self-disclosure; independently reproducible and auditable by third parties.

Continuous / near-real-time monitoring

Emissions tracked on an ongoing basis with alerts for anomalies; not a once-a-year snapshot.

Global asset coverage (190+ countries)

Coverage of industrial and commercial assets worldwide, not limited to North America or Western Europe.

Sweep is strongest in EMEA; global coverage is more limited.

GHG Emissions
Feature
Floodlight
Sweep

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.

Sweep covers Scope 3 supply-chain categories well; PCAF financed-emissions for financial institutions is limited.

Methane and fugitive emissions detection

Detection of methane leaks, venting, and flaring events often missed by factor-based inventories.

CBAM embedded emissions reporting

Facility-level embedded emissions per CN code for EU Carbon Border Adjustment Mechanism importer reporting.

Climate Risk
Feature
Floodlight
Sweep

Physical climate risk assessment

Asset-level exposure scores for flood, heat stress, wildfire, sea-level rise, water stress, hurricane, and other perils.

Transition risk assessment

Exposure to regulatory carbon costs, stranded-asset risk, and technology disruption under decarbonisation scenarios.

Climate Value-at-Risk (Climate VaR)

Probabilistic financial loss estimate under named climate scenarios, in the same units as market and credit VaR.

Regulatory Compliance
Feature
Floodlight
Sweep

CSRD / ESRS E1 compliance

Data mapped to CSRD ESRS E1 data-point IDs including E1-5, E1-6, and E1-9 financial-effects table.

Sweep is a CSRD-specialist and this is one of its strongest areas.

SFDR / Principal Adverse Impact (PAI)

PAI indicators for Article 8 and 9 funds including GHG intensity, biodiversity, water, and social metrics.

Auditability
Feature
Floodlight
Sweep

Full audit trail and data provenance

Every figure traceable to satellite overpass, model version, and confidence band - reproducible by external reviewers.

Sweep allows documents stored alongside data for a clean assurance trail - a genuine strength.

Limited assurance (ISAE 3410)

Methodology and documentation pack sufficient for limited assurance opinion without supplementary procedures.

Platform
Feature

Sweep

REST API access

Programmatic access to all data via documented REST API with pre-trade and portfolio query modes.

Honest verdict

Where Floodlight wins

Sweep is a well-designed carbon management tool but it relies on activity data provided by the client and their suppliers. Floodlight replaces or validates that self-reported layer with satellite-observed measurements - catching emissions events that Scope 3 questionnaires miss entirely. For financial institutions assessing lending portfolios and financed emissions, Floodlight provides the PCAF-aligned, satellite-verified asset-level data that Sweep is not designed to deliver. Floodlight also covers physical climate risk, Climate VaR, and CBAM, which fall outside Sweep's scope.

Where Sweep wins

Sweep is a category leader for collaborative Scope 3 data collection - its supplier engagement tools, embedded document storage alongside data, and CSRD audit-trail workflows are well-regarded among European corporates facing CSRD. For mid-market to large European companies whose primary need is a defensible CSRD disclosure, Sweep is a strong contender.
