Transparency verifiable, no greenwashing.
Our energy policy is based on five principles: document traceability, verification by independent third parties, open and auditable methodology, consistency between what we say and what we measure, and real commitment beyond the claims.
Three layers, each verifiable
When a visitor arrives at a site hosted on Replanta, the electricity consumed passes through three clearly identifiable layers. Each with its own energy policy and publicly auditable documentation.
Global distribution
Cloudflare CDN
Static content (images, CSS, JavaScript) is served from the node of Cloudflare closest to the visitor. This drastically reduces the transfer from the origin server.
Source server
Falkenstein Datacenter (Germany)
The server that hosts replanta.net and the sites of the Cedro plan operates from a certified German datacenter in Falkenstein, with 100% certified hydroelectric power.
Residual compensation
Tree-Nation Program
The small fraction of the footprint that is not avoided at source is compensated through reforestation in certified projects, with individual traceability per tree and public geolocation.
Don't take our word for it. Check the sources.
Our entire energy chain is backed by independent organizations that maintain public records. No private contracts, no opaque claims, no "trust us".
International organization that maintains the public registry of digital infrastructure powered by renewable energy. Replanta has been listed as a verified provider since 2026 and can be checked in its official public directory.

Public Data Panel
By clicking, the visitor accesses a page with live metrics of your domain: energy consumption of hosting, CO₂ avoided per visit and trees planted in your name.
Verifiable Data
The metrics are calculated with CO2.js and the Sustainable Web Design methodology. The compensation is backed by Tree-Nation with individual traceability per tree.
Commercial Argument
For your clients reporting CSRD, having this seal linked to a provider verified by GWF facilitates documentation Scope 3 of their corporate website.
How we calculate what we say
Claims about emissions, consumption, and compensation must have a traceable scientific basis. This is ours.
CO2.js + Sustainable Web Design
Emission estimation per visit based on page weight, the carbon intensity of the server's power grid, and the efficiency of the data center.
- SWD Model version 4 (updated to 2024).
- Electricity intensity factors by country.
- Green differentiation vs. standard origin.
Real-time monitoring
Real metrics from the source server captured with Prometheus and Grafana. Energy consumption, resource usage, uptime, efficiency per request.
- Auditable open source stack.
- Historical metrics preserved.
- Exportable for CSRD reporting.
Cross-checking
We contrast our estimates with external public calculators (Website Carbon, Beacon, Ecograder) for consistency. If the numbers don't match, we investigate why.
- Public reproducibility.
- Consistency with industry benchmarks.
- Documentation of deviations.
Calculate your site's footprint
If you want to see this methodology applied to your own domain, we have a public calculator that returns estimates of CO₂/visit, kWh/load, and Lighthouse scores in seconds.
Replanta Forest in Tree-Nation
We maintain a public forest in Tree-Nation with individual traceability per tree. Each tree has a unique ID, species, geolocation, and planting date. They are not opaque credits or future promises: they are planted trees.
Every active Replanta customer contributes to this forest by planting one tree per year in their name. The projects are divided between native reforestation and restoration of damaged ecosystems.
What we have, what we are doing, what is coming
Transparency includes acknowledging what is still not perfect. This is our honest roadmap for the coming months.
What we already have
- Verified replanting at The Green Web Foundation.
- Cedar plan in Falkenstein datacenter with certified hydroelectric.
- Cloudflare CDN 100% renewable in all plans.
- Tree-Nation program with public forest.
- Public digital footprint calculator with CO2.js.
- Carbon-negative seal for Cedar clients.
- Prometheus + Grafana monitoring of the origin server.
What we are doing
- CSRD Dashboard with exportable metrics for Cedro clients.
- Audit documentation ready for reporting Scope 3.
- Automatic generation of monthly PDF dossier per client.
- Progressive migration of Sauce and Oak plans towards improved traceability.
- Expansion of the reforestation program with projects in LATAM.
What's next
- Carbon-negative seal also available for Sauce and Oak plans.
- Public API for energy metrics by domain for integration.
- Annual impact reports individualized by client.
- Current hosting audit program for companies with CSRD.
- Secondary datacenter in LATAM with equivalent green criteria.
What reviewers and auditors ask us the most
Sustainability managers, IT directors, and ESG reviewers often raise the same questions. Here they are answered with the utmost accuracy possible.
How do I verify that Replanta's claims are true?
Our entire chain is backed by third parties with public records. Replanta is listed in the official registry of The Green Web Foundation and you can check it directly at its public verifier. The Falkenstein datacenter has a valid ISO 27001:2022 certification and documented hydroelectric energy. Tree-Nation maintains a public profile with each identifiable tree. You can verify all these sources independently without having to take our word for it.
What documentation do you provide for CSRD/Scope 3 audit?
For clients on the Cedro plan, we provide a dossier that includes: physical location of the datacenter, certification of energy origin, ISO certifications from the infrastructure provider, metrics of consumption for the reported period, documented CO2.js + SWD calculation methodology, and references to independent verification sources. The documentation is designed to integrate directly into CSRD reports under ESRS standards. If you want to better understand how it is structured, we have a complete guide on CSRD for SMEs and another on how to calculate Scope 3.
Why don't you state "100% renewable" in all plans?
Because only the Cedro plan operates on infrastructure with verified renewable energy at the source (Falkenstein datacenter). The Sauce and Oak plans operate with 2x emissions compensation via certified projects, which is valuable but not equivalent to verified renewable. Under the European Green Claims Directive, stating "100% renewable" without specific qualification is problematic. We prefer to be precise.
Is your profile on The Green Web Foundation active?
Yes. Replanta is officially verified in the register of The Green Web Foundation. You can check the domain replanta.net and the domains of our Cedro clients directly in their public verification tool. The infrastructure we use (Hetzner Cloud, Falkenstein) is also listed as verified in their public register.
How do you measure CO₂ per visit exactly?
We use the open source library CO2.js from The Green Web Foundation with the Sustainable Web Design version 4 model. The input variables are: weight transferred per load, carbon intensity of the electrical grid of the country of the datacenter, and green/ standard differentiator of the origin. The methodology is documented publicly and is reproducible. We do not use opaque proprietary calculations.
What happens to the trees if a client cancels the service?
The planted trees are already in the ground. They are not "un-planted" or removed from the Tree-Nation register. The environmental contribution of the client remains regardless of their continuity with Replanta. What is interrupted is the additional annual planting associated with the service.
Why don't you mention your shared hosting providers?
For the same reason that no shared hosting in the market publicly details its internal infrastructure layers: it is operational information that changes and does not add value to the end customer. What we do provide is transparency about what matters: verifiable energy origin, valid certifications, and calculation methodology. For clients with specific technical due diligence requirements, the information is shared under NDA.
How does Cedro compare to green hosting in hyperscaler?
Hyperscalers (AWS, GCP, Azure) operate with annual matching of renewables: they buy certificates equivalent to their total annual consumption, but do not guarantee that every hour of your site is powered by renewable energy. Falkenstein operates with certified hydroelectric power 24/7 directly. For advanced CSRD reporting, this difference matters. Additionally, at Cedro you have dedicated infrastructure and direct support, not shared infrastructure in global data lakes.
