Transparent, precise, regional: How Tree.ly differentiates itself in the CO₂ market

Efforts to keep global warming below 1.5 degrees are crucial. However, private funds flowing into climate protection projects worldwide have, unfortunately, been ineffective. In this post, we take a close look at how Tree.ly is setting new standards with transparency, precision, and regional focus.

Challenges in the CO₂ market

Ineffectiveness of previous CO₂ project types

  • Only about 2% of projects in the Clean Development Mechanism, the first major offsetting program, simultaneously exhibit additional and conservative certificate generation (Cames et al. 2016). Thus, 98% of these projects are either overestimated (generate too many credits) and/or would have occurred anyway.

  • A study of all major cookstove projects revealed that only about 1 in 6 issued tCO₂ has actual impact (Gill-Wiehl et al. 2023).

  • Improved forestry and REDD+ projects mostly suffer from significant overestimation of impact due to non-conservative baselines, problems with leakage, and inadequate safeguards against setbacks (Guizar-Coutiño et al. 2022, West et al. 2020, West et al. 2023). Learn more in relevant articles, including The Guardian, Thred and The New Yorker.

Tree.lys perspective for real impact

The identified problems do not stem from incompetence or malice but from an immature methodology and the challenging circumstances of data, monitoring, and dynamics in developing countries.

Other providers

Old approach

The focus is on compensation, offsetting your own carbon footprint

Problems of these projects

Certificates are issued before the completion of the projects

Questionable project standards, unclear control mechanisms

Mainly unclear use of funds

Anonymous tCO₂

Significant overestimation of impact due to aggressive calculation bases

Lack of transparency


Our approach at Tree.ly

Real Impact

Taking responsibility, making a contribution to climate protection

Benefits with Tree.ly

Certificates are issued annually after thorough verification of the measures

Annual inspection by TÜV

100% earmarked use of funds

Immediate support for the forest owner

Realistic calculation of impact through the TÜV-confirmed conservative calculation basis

100% transparency through project registry & action plans

Regional focus in forest climate protection projects

While capital flows to the Global South must be a key component of global climate efforts, Tree.ly starts at home first. Tree.ly projects take place in the home countries of emitters. This way, we not only avoid double counting under Paris Agreement Article 6 but also contribute to the EU's ambition to become the first climate-neutral continent by 2050.

But how do we avoid endemic issues in forestry projects worldwide? Our methodology according to ISO-14064-2 (2019) has been audited and validated by TÜV Nord. The points mentioned below have been confirmed by TÜV.

Evidence of effectiveness of CO₂ projects with Tree.ly

  • Additionality in commercial forests is captured in the baseline based on yield tables, strong historical data in the respective forest, and forestry use.

  • Our calculation methods and assumptions have been scrutinized at each step and assessed by TÜV as conservative.

  • Internal leakage is avoided by our forest owners committing with their entire productive forest area. External leakage is also demonstrably avoided.

Tree.ly goes beyond mere intention and relies on transparency, precision, and regional integration to make a real difference in the voluntary CO₂ market.
