Advanced features

What the PRO plan includes.

Everything you need to go from a rough estimate to figures your clients, banks and funding bodies can rely on.

Full Scope 1, 2 and 3

A boundary that covers your entire value chain, not just direct emissions.

Multi-year dashboard

Track how your emissions change over time and compare one year with the next.

Expert review

A zeroCO2 expert checks data, sources and emission factors before delivery (human-in-the-loop).

Full audit trail

Every data point is tracked and documented, ready for external verification and compliance.

Tailored report

A bespoke PDF for clients, banks, tenders and ESG/CSRD reporting.

Dedicated consultancy

A reduction roadmap built together with a zeroCO2 consultant.

Advanced analysis

Carbon footprint, LCA and Scopes: the complete analysis.

The methodology behind a PRO report, built to stand up to an external audit.

Carbon footprint

The total amount of greenhouse gases emitted, directly and indirectly, expressed in tonnes of CO2 equivalent and verified by a reviewer.

LCA analysis

Life Cycle Assessment with primary data, not just industry averages, for sturdier results you can defend in an audit.

Why an expert-reviewed report

Clients, tenders, the CSRD directive and ESG ratings all demand verifiable data: a PRO report lowers the risk of your figures being challenged.

What are Scope 1, 2 and 3?

In the PRO version, every Scope is calculated with real data and traceable emission factors according to the GHG Protocol, ready for an external audit.

SCOPE 18%

Verified direct emissions: boilers, fleet, production processes.

SCOPE 217%

Purchased energy, with emission factors tracked contract by contract.

SCOPE 375%

Value chain mapped by GHG Protocol category, with documented sources.

FAQ

Before you sign up: the most common questions.

What does the PRO carbon footprint analysis include?

The PRO version covers full Scope 1, 2 and 3 with real data, review by a zeroCO2 expert, a multi-year dashboard, an audit trail and a tailored report ready for clients, tenders and ESG/CSRD reporting.

How much does the PRO version of the calculator cost?

Activation is a one-off €1,500 + VAT per type (company, product or event). You pay by credit card via Stripe once your company is registered.

What does human review of the data mean?

Every analysis is checked by a zeroCO2 expert before delivery: we verify the sources, emission factors and consistency of the data you upload, so the result stands up to an external audit.

Does the report comply with ISO 14064 or ISO 14067?

The PRO calculation method follows the GHG Protocol and is set up for compliance with ISO 14064-1 and ISO 14067, depending on the boundary you choose.

What's the difference between a product carbon footprint and an LCA?

An LCA (Life Cycle Assessment) measures a product's impact across its life cycle. The PRO product calculator covers cradle-to-gate or cradle-to-customer (delivery) boundaries (ISO 14067): raw materials and their transport, production at your company, packaging and delivery, where applicable. The product's use phase and end of life are not included, and neither is any further processing by third parties: if yours is an intermediate product, the reference unit is the product as it leaves your company.

Is my company's data confidential?

Yes. Your data stays confidential, is processed in line with the GDPR and is never shared with third parties without your explicit consent.

Can I switch from the Free version to PRO later?

Yes: you can start with the free estimate and activate PRO at any time, reusing the information you've already entered.

How long do activation and the analysis take?

Activation is immediate once you've paid; the full analysis usually takes 5 to 10 working days, depending on how quickly the data is available.
