Contributor space
Follow your projects. Prove your commitments. Engage your teams. The contributor space brings together what you need to manage your carbon contribution, and to talk about it accurately.

Your board wants figures. Your teams want meaning. Your clients want proof. Your space gives you all three, up to date, in one place.
Follow




Expected carbon credits, projects on the map, the latest news from the field: the answer fits on the first page. No more gathering information every time someone asks.
Planting, maintenance, visits: every stage of the project comes with its photos. A true story to tell, rather than an abstract figure.
Allocate your expected carbon credits to a brand, a client or an event. Each allocation produces its certificate, verifiable online.
Contracts, invoices, attestations, project reports: everything is filed and downloads in one click. For your CSR report, a tender or an audit.
Centralise
Have you also funded projects elsewhere, with other operators or directly? We bring them into your space. Monitoring, documents, volumes and communication are then managed in one place.

The field
News from your projects arrives season after season, with photos, and by email if you wish. Real images for your teams and your clients.




Prove
Your logo, the project, the allocated tonnes and a verification link. Your client receives the certificate; anyone can check it.

Communicate



The key climate dates of the year, with texts and visuals ready to publish, reviewed to stay accurate. You save time and avoid risky wording.
Your commitment and your projects on a page to share: website, email signature, tender response, recruitment.
The seal for your website, project photos, visuals for your social networks. Up to date, and downloadable in one click.
Engage
A link or a QR code is all it takes. Your employees vote, answer, sponsor; you follow participation live, with a report to share internally.



A climate quiz in your colours, with your own questions if you wish.
A vote to decide together which project the company will support.
Everyone receives a tree from a project you fund, and its certificate.
Measure
A built-in carbon calculator estimates the footprint of your activities, such as a team trip, with your own resources. A clear result, ready to share.

Everyone accesses the space with their own account.
A message when a project moves forward or a certificate is issued, as you prefer.
The same space, designed for both screens.
Answers to common questions, and a direct line to Stock CO2.

Every certificate can be verified online by anyone who receives it.
A demonstration on an example close to yours, and answers to your questions.
