Impact Certification

Reforest our Cities

Amplify impact for people and environment

We certify the design and implementation of high-value planting projects in cities. Companies can provide funds for projects that align with corporate social and environmental responsibility goals and improve communities across the country.

Impact Certification provides standardized project reporting with science-based metrics and scores for social equity, human health, and environmental impacts. 

CFC’s Impact Certification provides Microsoft with quantified, reportable outcomes that are central to ensuring the most positive impact from our investments. We are excited to have a scoring mechanism to help us evaluate each project’s ability to improve social equity, human health, and ecosystem services.

Enrich Your Community

Leverage dollars to drive change

From cooling hot city streets to inclusive community design, Impact Certification encompasses the first ever holistic environmental and social framework for assessing and demonstrating impacts of trees.

Trees can transform a neighborhood and the lives of its residents. However, nonprofits and government leading projects often struggle to find upfront funding to plant trees. Private-sector dollars can accelerate projects and spark action.

We match your funds with simple, reliable, and shovel-ready projects led by local operators in three simple steps.

Impact Certification is the first of its kind to describe science-based health and equity impacts from tree planting projects. Companies can meet their corporate objectives and employees can adopt a project that directly benefits their own community.

Measure Results

Science-based impact framework

Access and immersion in nature can have profound impacts on our lives. Based on the latest science, our Impact Scorecard describes and measures human health, social equity, and environmental benefits of each project. 

Impact projects do not generate a carbon credit, but provide metrics and scores that illustrate the value of trees.

Three Focus Areas, Five Impact Themes

Report on Your Investment

Efficient and standardized format

At the completion of a project, we issue a high-level Impact Summary and a detailed Impact Report. Funders can share outcomes to their communities and stakeholders.

The 17 United Nations Sustainable Development Goals, or SDGs, are a global call for action. We map project impacts to the SDGs so you can easily report on how your business is taking steps towards achieving the global goals. See a sample Impact Summary.

Impact Certification FAQs

We suggest a minimum investment of $10,000. Reach out to CFC at and we will connect you with a project that meets your goals.

Impact Certification is the first-ever tool for assessing and demonstrating the science-based impacts of a tree planting project that incorporates social equity, human health, and the environment.

Non-profit organizations or local government agencies can lead an Impact Project. We provide a Project Plan, Impact Scorecard, and Guidebook that describes the health, equity, and environment considerations for project design. Design factors such as the number of trees planted, site selection, participatory process, and more are chosen by the entity leading the project, along with desires of the community. Contact us at to discuss your project ideas.

A Carbon+ project requires a 25-year time commitment and produces carbon credits that can be sold to generate revenue for tree maintenance and stewardship. An impact project does not require a time commitment and does not produce a carbon credit. An impact project receives up front funding to design and implement the project.
