Carbonfund operates as a 501(c)(3) nonprofit foundation that enables businesses, organizations, and individuals to reduce and offset their carbon footprint through a diverse portfolio of third-party validated carbon reduction projects. The organization offers a flexible pricing structure where supporters can make tax-deductible donations to offset specific amounts of carbon emissions, with options ranging from small one-time contributions for individuals to comprehensive carbon management programs for corporations. According to the Environmental Protection Agency, this type of verified offsetting plays an important role in comprehensive carbon management strategies when combined with direct emission reduction efforts.

The foundation supports three main categories of carbon reduction projects: forestry and conservation initiatives that protect and restore ecosystems, renewable energy projects that displace fossil fuel generation, and energy efficiency programs that reduce overall energy consumption. Each project undergoes rigorous validation by standards such as the Verified Carbon Standard, Gold Standard, and Climate Action Reserve to ensure that emission reductions are real, additional, and permanent. Carbonfund’s transparency in project selection and verification aligns with best practices outlined by organizations like the World Resources Institute for credible carbon market participation.

Through its CarbonFree® Product Certification program, Carbonfund helps businesses demonstrate climate leadership by certifying that products, services, or events have had their carbon emissions calculated and offset. This program provides companies with a recognizable logo to communicate their climate commitment to consumers while supporting high-quality carbon reduction projects. The organization also maintains extensive educational resources about climate science and solutions, helping supporters understand not just how to offset emissions but how to reduce them through efficiency improvements and lifestyle changes.
