    Terms and Conditions

    This is a courtesy translation. In case of any discrepancy, the Spanish version of this document shall prevail.

    Last updated: 11/07/2026

    1. Purpose and acceptance

    These Terms and Conditions (hereinafter, "the Terms") govern the use of the Descarboniza platform accessible at https://www.descarboniza.es, owned by Jesús Morán Morán (Tax ID 44789317Z), with registered address at Calle Villafranca 77, Almendralejo (Badajoz), Spain.

    Use of the Website — whether as a visitor, registered user or subscriber — implies full and unreserved acceptance of these Terms, as well as of the Legal Notice, the Privacy Policy and the Cookie Policy.

    2. Description of the service

    Descarboniza is an editorial platform and set of digital tools for the sustainable construction sector. It includes, among others:

    • A directory of manufacturers, construction companies, architecture studios, engineering firms, distributors, organisations and projects.
    • A catalogue of Environmental Product Declarations (EPDs) verified in accordance with EN 15804.
    • A construction-systems comparator (carbon footprint, cost, U-value, condensation, CTE HE compliance).
    • A CTE HE thermal calculator.
    • A radon calculator.
    • A scanner and related tools for Energy Savings Certificates (CAE).
    • Editorial content, news and educational materials.

    The scope of these features may evolve. Descarboniza reserves the right to add, modify or withdraw tools and content at any time.

    3. User registration

    Certain features require creating an account. Registration and authentication are handled by the provider Clerk Inc. ("Clerk"). By registering, you accept, in addition to these Terms, Clerk's terms insofar as they affect the authentication process.

    The User undertakes to provide truthful information, keep it up to date, and safeguard their login credentials. The User is responsible for immediately reporting any unauthorised use of their account to hola@descarboniza.es.

    Descarboniza may suspend or cancel accounts that breach the Terms, misuse the platform, or infringe third-party rights.

    4. Subscription plans and payments

    Some features may require a subscription plan. The features, prices and duration of each plan are published on the /plans page and, where specific, prevail over the general provisions of these Terms.

    Payments are processed through specialised external providers (for example, Stripe). Prices are expressed in euros and include, where applicable, the relevant taxes. Descarboniza does not store card details.

    Unless otherwise stated, subscriptions renew automatically at the end of each period. The User may cancel the renewal at any time from their account or by emailing us, with the cancellation taking effect at the end of the current period.

    Right of withdrawal (consumers): under Royal Legislative Decree 1/2007, consumer Users have 14 calendar days to withdraw from the contract, unless they have started using the digital service with their express consent and with knowledge that they thereby lose that right. To exercise it, simply send an email to hola@descarboniza.es stating your wish to withdraw.

    5. Use of the tools and limitation of technical liability

    The calculation and comparison tools — comparator, CTE HE thermal calculator, radon calculator, CAE scanner, carbon-footprint comparisons, etc. — provide indicative estimates based on public data, verified EPDs and current regulations.

    The results do not replace the professional judgement of architects, engineers, qualified technicians or legal and tax advisors. The final decision on any project, material or construction solution rests entirely with the User and their technicians.

    Descarboniza does not guarantee the accuracy, completeness or real-time updating of data provided by third parties (manufacturers, verification bodies, public administrations) and disclaims any liability for technical, financial or legal decisions made on the basis of the tools or the directory content.

    6. Content published by Users

    Professional Users may request the publication of company, material, project, EPD or other sector-related listings. By submitting content to Descarboniza, the User:

    • Warrants that they own or hold the necessary authorisations for the texts, images, logos, technical data and other elements provided.
    • Grants Descarboniza a non-exclusive, worldwide, royalty-free licence to reproduce, publicly communicate and make that content available on the Platform and on its associated communication channels.
    • Accepts that Descarboniza may edit, contextualise or reject the content for editorial, quality or regulatory-compliance reasons.
    • Assumes responsibility for the truthfulness and legality of the content submitted.

    Descarboniza will remove, as promptly as possible, any content subject to a well-founded claim of infringement of third-party rights.

    7. Prohibited conduct

    The User undertakes not to use the Platform to:

    • Disseminate false, misleading or defamatory information, or information that infringes third-party rights.
    • Carry out mass or automated scraping of content without authorisation.
    • Introduce malicious software, attempt to access restricted areas, or compromise the security of the service.
    • Impersonate third parties or create multiple accounts for fraudulent purposes.
    • Use the tools for purposes incompatible with their informational and professional nature.

    Breach may result in immediate suspension of the account and, where applicable, the pursuit of appropriate legal action.

    8. Intellectual property

    The editorial content, design, source code and organisation of information are owned by the site owner or its licensors. Granting access to the Platform does not imply any waiver, transfer, or full or partial licence of intellectual or industrial property rights.

    The User may view, print, copy and store content solely for personal and individual professional use, always citing the source. Commercial redistribution without written authorisation is expressly prohibited.

    9. Service availability

    Descarboniza undertakes to use reasonable means to keep the Platform operational, but does not guarantee uninterrupted availability. Downtime may occur due to maintenance, updates, technical incidents or force-majeure causes, without giving rise to any compensation.

    10. Amendment of the Terms

    Descarboniza may amend these Terms to adapt them to regulatory, technical or business changes. The version in force will always be the one published on this page, indicating the date of the last update. Continued use of the Website after publication of a new version implies acceptance of it.

    11. Governing law and jurisdiction

    These Terms are governed by Spanish law. Disputes shall be submitted, save for any mandatory rule to the contrary, to the Courts of the consumer's domicile when the User acts as a consumer, and otherwise to the Courts of the owner's domicile.

    In accordance with Regulation (EU) 524/2013, consumers resident in the European Union may access the European Commission's online dispute resolution platform at https://ec.europa.eu/consumers/odr.

    12. Contact

    For any query relating to these Terms, you can write to hola@descarboniza.es.
