CO₂ credits with tested quality

Every year, our projects are validated by an external body (TÜV AUSTRIA) and the CO₂ credits are then certified. We accompany the entire certification process up to validation and finally receive annual monitoring by TÜV AUSTRIA. In this way, we can guarantee a sustainable contribution to global climate protection.

Our Process

How to support forests in your area

The first steps are the most important: Understand your company's emissions, take steps to avoid your emissions as much as possible, and reduce them in the long term. After that, you can support our climate protection project to sustainably promote regional forests.


Transparent accounting of all greenhouse gas emissions

The first step in a Paris-compatible climate strategy is to transparently account for all greenhouse gas emissions along your value chain (Scopes 1, 2 and 3). A good accounting is highly transparent, regularly updated, and serves as a basis for defining reduction and financing measures.


Reduction of all greenhouse gas emissions

The reduction measures should be part of an ambitious target towards the 1.5°C goal. The Science Based Targets initiative Net Zero Standard can be used as a guideline for reduction.


Support climate protection projects

By financing verified climate protection projects, you strengthen global climate protection and drive the necessary systemic transformation. Tree.ly projects are certified by TÜV and implemented according to ISO 14064-2.


Designated payment to forest owners

100% of your payments go directly to the forest owners. Your contribution ensures long-term sustainable forest management.


Transparent communication

You can share your climate protection commitment on various channels with materials provided by Tree.ly. This further enhances the effect.

Support forest projects now

Take responsibility by supporting a forest climate protection project with Tree.ly. 100% of the funds raised go to the forest owners and are designated for sustainable forest management.

Quote from a forest owner

"Additional revenue from the sale of CO₂ credits will allow the Forest Service to invest in forest maintenance and, more importantly, to ensure "proper forest management" with sufficient skilled forestry personnel."
