Sweep

Sweep suits event organizations that need many teams and suppliers to contribute to a governed sustainability dataset. It is most useful when events sit inside an ongoing corporate reporting program; a one-off event calculator is a different procurement need.

Best For

+ Event operators collecting carbon data across several business units or locations
+ Venue and production groups coordinating supplier and procurement inputs
+ Sustainability teams that need traceability and review controls for recurring disclosures

Not For

− One-off organizers seeking an instant attendee footprint without an organizational setup
− Buyers requiring a published flat event price without a scope discussion
− Teams unwilling to assign ownership for supplier data and emissions-factor review

Key Capabilities

✓ Collect organizational activity and spend data for carbon measurement

✓ Organize sustainability information across entities and geographies

✓ Invite suppliers and internal contributors through structured collection workflows

✓ Assign role-based access for data responsibilities

✓ Analyze carbon hotspots through dashboards and scenario workflows

✓ Maintain data lineage and audit trails for review and external assurance work

✓ Export reporting data and expand from Starter into broader organizational/value-chain needs

Honest Limitations

Organizational scope adds setup work

Events need to be mapped into the chosen entity, supplier and activity structure. Per-event allocation and comparison should be demonstrated with a sample dataset.

Pricing needs a current quote

The primary Starter and platform pages describe packages without establishing a universal numeric subscription or per-event rate.

Data and factors still require review

Angelique V.’s November 2025 G2 account said emissions-factor updates were manual in her workflow. Treat this as a dated fit question about ownership and versioning, not a universal current product restriction.

Software does not establish assurance by itself

Audit trails and reporting features support review, but input completeness, methodology and any independent assurance remain separate responsibilities.

Pricing Breakdown

Broader organizational and value-chain scope	Quote required	Confirm the upgrade, collaboration, supplier engagement, governance and reporting capabilities required for your operation.

Hidden Costs to Watch

! Supplier coordination, data cleaning and methodological decisions require internal or advisory effort.
! Confirm integrations, implementation, support, extra entities and assurance assistance in the package.
! Event-level reporting and organizational reporting may require different configuration and staff ownership.

Sweep is a coordination and reporting system for organizational sustainability data. An event business can use that structure for the travel, energy and purchasing that arise across its event portfolio, provided the allocation rules are agreed.

Its value should be evaluated through the people who supply and review the data. A sample workflow involving an event team, a venue and a supplier is more informative than assuming that a dashboard alone resolves incomplete records or reporting methodology.

The fit assessment follows documented scope. Reviews are dated individual accounts; no hands-on product test or vendor interview is claimed.
