Reforest our Cities

Amplify impact for people and environment

We certify the design and reporting of high-value tree planting projects in cities. Companies can provide funds for projects that align with corporate social responsibility goals and advance environmental justice for 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.

Equity and Health

Leverage dollars to drive change

From cooling hot city streets to inclusive co-creation with frontline communities, Impact Certification is the first ever science-based and standardized framework to assess, demonstrate, and report on the impacts of trees.

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

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.

Design Guide

Optimize science-based impacts

A project design tool prompts ideas and encourages forward-thinking for the location and process of planting trees. Human health, social equity, and environmental benefits are linked to the latest science and best practices from subject matter experts.

Impact Report

Share return on investment

Funders can share outcomes with their communities and stakeholders in an efficient and consistent way. CFC issues a high-level Impact Summary and a detailed Impact Report.

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

The 17 United Nations Sustainable Development Goals, or SDGs, are a global call for action. Project impacts are mapped to the SDGs so you can easily report on how your business is taking steps towards achieving the global goals.

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.
