Carbon+Alt+Delete

Carbon+Alt+Delete is a relevant option when an event operator already works with a sustainability consultant who will own the inventory methodology. It makes less sense as a direct purchase for a one-off host: the consultant licensing boundary and client-access arrangement are central to the product.

Best For
  • + Sustainability consultancies serving venue, production or event-operating businesses
  • + Event organizations seeking client access within a consultant-managed carbon inventory
  • + Practitioners who need transparent factor and business-travel methodology choices
Not For
  • − Event hosts expecting to buy a direct self-service company license without a consultant
  • − Buyers needing a full multi-impact life-cycle assessment rather than the stated carbon scope
  • − Teams expecting software outputs to replace professional boundary, factor and uncertainty review
Key Capabilities
✓ Collect client activity data through requests, manual entry and bulk Excel import
✓ Connect data through a documented API where the consultancy implements it
✓ Account for operational electricity, purchased goods/services, waste and business travel
✓ Choose from embedded emissions-factor databases or define custom factors
✓ Inspect flight methodology including the radiative-forcing choice in business travel
✓ Prepare carbon inventory reporting and scenario/target workflows
✓ Provide client access and maintain supporting records for inventory review
Honest Limitations

Direct licensing is limited to consultants

Company sustainability managers can use the platform through a consultancy, according to the current vendor FAQ. That access model should be clear before a demo.

Carbon scope is narrower than full LCA

The vendor says product carbon footprints are possible but full multi-impact life-cycle assessments are not. Its CSRD coverage is scoped to ESRS E1, not every disclosure requirement.

Historical import limitations need a representative test

Bianca W.’s September 2024 Capterra account reported more manual work for spend data outside Category 1. This is a dated user finding to test against current imports, not a universal present restriction.

Some document workflows may need workarounds

Sander M.’s October 2025 review said one supporting document could not be attached to several lines in the situation he tested. Confirm the current evidence-linking workflow with your own inventory.

Pricing Breakdown
Plan Price Details
Consultancy software license Quote required The primary product page bases pricing on the number and type of clients served. A trial can be arranged.
Client access through a consultancy Confirm with the consultant The organization’s access, advisory work and any per-client charge depend on its consultant arrangement; they are not a direct self-service vendor tariff.

Hidden Costs to Watch

  • ! Consultancy methodology, data preparation and assurance work may be separate from the software license.
  • ! Confirm client allowances, API work, training, renewal and data-export rights in writing.
  • ! Event-level allocations need an agreed approach within the wider organizational inventory.

Carbon+Alt+Delete serves the practitioner doing the inventory. An event operator can participate as a consultancy client, supplying energy, travel, purchasing and waste records while the consultant defines the boundaries and methods.

That distinction prevents a misleading comparison with a guest-facing event calculator. Evaluate the client-access workflow, traceability and advisory agreement together; a software quote alone does not establish the total cost of a defensible inventory.

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