Projet Celsius is a French bureau d'études focused on climate and eco-design — in other words, a specialist research and consulting firm. The site does not present it as a typical SaaS platform; instead, it emphasizes in-depth research delivered by a team of engineers and PhDs to help organizations understand, manage, and communicate their climate strategies. Example clients include Institut Pasteur, SNCF, Würth, Institut Curie, Radio France, ESSEC, Polytechnique Paris, and others.
Based on the website content, Projet Celsius’s core strengths are carbon accounting and environmental assessment: Bilan Carbone®, GHG Protocol, ACV ISO 14040, CSRD/ESRS, RE2020, eco-design, and CBAM/MACF-related analysis. It serves sectors including healthcare and research, textiles, transport and mobility, services, construction, and aviation. Its articles provide relatively in-depth explanations of CBAM, the phase-out of free ETS allowances, real carbon data, product carbon footprints, and their relationship with ESRS E1, suggesting that its strength lies in consulting delivery that combines regulatory expertise with methodology.
The site does not disclose packages, pricing, billing methods, contract models, or delivery timelines. Nor does it show common SaaS features such as a dashboard, reporting system, API, user permissions, or third-party integrations. The only “free” item mentioned is a climate maturity diagnostic that requires no registration and takes about 5 minutes to complete. Therefore, if evaluated as enterprise software, the information provided is limited; if evaluated as a professional consulting firm, its industry content and credentials are more substantial.
Its advantages are strong professional depth, covering high-demand corporate topics such as Bilan Carbone, LCA, CBAM, CSRD, and RE2020, along with relevant endorsements from ADEME, Bpifrance, ABC, and others. Its content is structured and visually oriented, making it suitable for organizations that need to turn complex climate compliance requirements into management decisions. The downsides are a lack of pricing transparency and no disclosure of software capabilities, collaboration permissions, data security, deployment, or integration options. The website is mainly in French, which may create a language barrier for international clients.
It is best suited to companies in the French or EU market facing requirements around carbon audits, CSRD/ESRS, CBAM, building-related RE2020, product LCA, and eco-design, especially in sectors such as industry, construction, healthcare, textiles, and transport. Chinese companies exporting steel, aluminum, cement, hydrogen, fertilizers, or related downstream products to the EU may find its CBAM methodology content useful, but any actual engagement would require confirmation of language support, cross-border service arrangements, payment, and data compliance. The site does not provide information on access or payment from China, so its China access status is unknown. If local implementation is required, companies may also want to evaluate China-based ESG/carbon management software and LCA consulting firms.
