Audit any company's sustainability narrative — on demand.

Running an AI analysis consumes electricity (server compute) and water (data-centre cooling). We disclose our own estimates so you can weigh the cost — the same transparency we expect from the brands we audit.

Mossy runs on the Lovable AI Gateway, which currently serves Google Gemini and OpenAI GPT-5 models. Estimates are based on Google's 2024 Gemini inference disclosure (median text prompt: 0.24 Wh, 0.26 mL water, 0.03 g CO₂e), Ren et al. (2023) on data-centre water cooling, and the IEA (2024) EU grid intensity (~230 g CO₂e/kWh). OpenAI has not yet published per-inference disclosures, so GPT-5 figures are extrapolated from comparable published data — we will update when official numbers are released. Image and PDF analyses are modelled as ~4× heavier than a text-only prompt. Actual values vary by model, data centre, and grid mix.

FAQ

Is this a compliance verdict?

No. Mossy is a communication tool, not a legal judgement. It identifies where sustainability claims may be vague, unsubstantiated, or inconsistent with major regulatory frameworks — but it does not constitute legal advice and should not be used as the sole basis for compliance decisions. If you have specific legal concerns about your sustainability communications, consult a qualified legal professional.

How is the free Message Scan different from the Pro Website Audit?

The free Message Scan lets you paste marketing copy or upload an image and get an instant verdict — flags, severity levels, and regulatory references — at no cost and with no sign-up required. It checks a single piece of content against six international frameworks in seconds. Mossy Website Audit is a deeper, structured assessment. It crawls an entire website and scores it across 46 criteria in four pillars — Content, Aim, Reporting, and Engagement — producing a detailed report with pillar scores, strengths and gaps, remediation advice for every failed criterion, and a downloadable PDF. Free users can run one Website Audit preview — one time only, not recurring monthly — and see their overall score and strengths. The full breakdown, remediation advice, and PDF download require a Pro subscription or a one-time Website Audit purchase.

Which frameworks do you check against?

Mossy cross-references claims against six major international frameworks: ISO 14021:2016 — Self-declared environmental claims; FTC Green Guides (USA) — Environmental marketing guidelines; UK Green Claims Code — CMA six principles for green claims; CSRD/ESRS — EU Corporate Sustainability Reporting Directive; EU Directive 2024/825 — Empowering Consumers for the Green Transition; EU Green Claims Directive — Proposed substantiation regime.

How is the score calculated?

The CARE score is based on the CARE model developed in Rêgo, S. (2024), Comunicação para a Sustentabilidade, PhD thesis, Universidade do Minho. The model evaluates 46 binary criteria across four equal pillars — Content, Aim, Reporting, and Engagement. Each criterion is either met or not met. Each pillar score is the percentage of criteria met within that pillar. The overall CARE score is the unweighted average of the four pillar scores. Verdicts: 0–34 Weak · 35–59 Developing · 60–79 Credible · 80–100 Exemplary.

What does it cost?

Mossy has four tiers: Free — Mossy Message Scan, 3 analyses per month, no sign-up required; Pro — €49/month or €349/year — unlimited analyses, full audit history, exportable PDF reports; Website Audit — €149 one-time — single full website audit with complete breakdown and PDF report; Enterprise — Custom pricing — portfolio audits, dedicated onboarding, direct access to the researcher.

What happens to the text and images I submit?

Text and images you submit are sent to an AI model for analysis and are not stored permanently on Mossy's servers after your session. Do not submit confidential, sensitive, or personally identifiable information. Submissions are sent to an AI provider — please review their data processing terms if this is relevant to your organisation's policies.

Which languages are supported?

Mossy Message Scan accepts text in any language. Mossy Website Audit crawls websites in any language. Report output language currently defaults to English. Additional output languages are on the roadmap.

What if a website blocks the crawler?

Some websites use bot protection that prevents automated crawling. If Mossy cannot access enough content from a site, the audit will return an incomplete result rather than an inaccurate score. In this case you will see a notification and can try re-running the audit. If the site consistently blocks crawling, a manual audit may be required — contact us to discuss options.

Do you offer refunds?

For one-time Website Audit purchases, if the audit fails to complete due to a technical error on our side, we will re-run it or issue a full refund. For Pro subscriptions, you can cancel at any time and will retain access until the end of your billing period. We do not offer refunds for completed audits or partially used subscription periods. If you have an issue, contact us at hello@mossy.green and we will do our best to resolve it.

Is Mossy based on academic research?

Yes. Mossy is built on the CARE model developed in Comunicação para a Sustentabilidade — a PhD thesis by Dr. S. Rêgo, defended at Universidade do Minho in 2024. The CARE model (Content · Aim · Reporting · Engagement) provides a peer-reviewed framework for evaluating the quality and credibility of organisational sustainability communication. The full thesis is publicly available at the University of Minho repository.

How accurate is the CARE score?

Mossy has been calibrated against manual expert assessments across multiple sites. Scores are typically within ±8 points of a manual evaluation. Because the analysis is AI-generated from publicly available content, scores may vary slightly between runs and may be conservative on very large enterprise sites with extensive sustainability sections. The score reflects what is visible and accessible on the website at the time of the audit — not internal practices, unpublished commitments, or offline activity. For a verified manual audit grounded in the full CARE methodology, contact us.

Can I audit my own company's website?

Yes — and this is one of the most valuable uses of Mossy. Running a Website Audit on your own site before a client, investor, or regulator does gives you a clear picture of where your sustainability communication is strong and where it needs work. The remediation advice for each failed criterion tells you exactly what to fix and which regulatory framework it relates to. Many communications professionals and ESG managers use Mossy as a regular self-assessment tool.

What is the CARE model?

CARE stands for Content, Aim, Reporting, and Engagement — four pillars that together define what credible, substantiated sustainability communication looks like. Content — What you say and how clearly you say it. Are claims specific and evidence-backed? Is the language free of vague or banned terms? Aim — Whether sustainability sits in your purpose, mission, vision, and values. Are commitments explicit, verifiable, and aligned with international frameworks? Reporting — Targets, governance, and transparent disclosure. Is there a named sustainability team? A downloadable report? Certified performance data? Engagement — Real two-way dialogue with stakeholders. Are there participation tools, feedback mechanisms, and calls to action beyond broadcast communication? The CARE model was developed through doctoral research at Universidade do Minho and cross-referenced with ISO 14021, the FTC Green Guides, the UK Green Claims Code, CSRD/ESRS, and EU Directive 2024/825.
