Frequently asked questions
Frequently asked questions
Prices, scope, Bpifrance funding, differences between consultancies: the questions we are most often asked about the cost of a Bilan Carbone®.
The price mainly depends on organisation size and scope complexity, under the Bilan Carbone® v9 method (ABC). For an SME with fewer than 50 employees, allow €6,000 to €12,000 excl. VAT, compared with €15,000 to €25,000 excl. VAT for a mid-sized company with 250 to 500 employees. Above 500 employees, ranges run from €20,000 to €40,000 excl. VAT depending on internal maturity, tool integration and the support format. See our full cost analysis.
Three main options: use Bpifrance's Diag Décarbon'Action, which subsidises 40% of the cost (€6,000 excl. VAT payable by you) for companies with fewer than 500 employees and no GHG assessment for 5 years (see our eligibility checker); assign an internal lead to handle data collection (saving 3 to 5 consultant-days); and narrow the scope to material categories before extending to upstream scopes. Combining the three can halve the bill.
Four factors explain the differences: the consultant's daily rate (€800 to €1,500 excl. VAT/day depending on seniority), the estimated number of consultant-days (3 to 20 depending on methodological depth), the level of support (internal training, joint project management, turnkey project), and the integration of proprietary tools. An itemised quotation makes like-for-like comparison possible. See our comparison of consultancies and SaaS platforms.
It is an indicative figure, rather than a quotation. The displayed range is calibrated against 80 Bilan Carbone projects carried out by Celsius since 2019, with typical accuracy of ±25%. For a fixed quotation tailored to your exact situation (precise scope, available data, regulatory deadlines: see our BEGES checker), a 30-minute discussion with a consultant is needed.
The regulatory BEGES requirement mandates publication every 4 years for companies with more than 500 employees (see Article L229-25), and every 3 years for the public sector and local authorities. Redoing a full assessment annually is not appropriate: emission factors change little and the cost is not justified. However, light annual monitoring of the main categories (energy, travel, purchases) is good practice for managing the decarbonisation pathway.
The BEGES requirement (see Article L229-25) covers companies with more than 500 employees (250 in French overseas territories), local authorities with more than 50,000 inhabitants and public legal entities with more than 250 staff. Below this threshold, Bilan Carbone® remains voluntary but is increasingly requested through cascading demands: public contracting authorities, mid-sized customers in the supply chain, bank financing under ESG criteria. See our CSRD guide for SMEs and our BEGES checker to confirm your exact situation.
