Carbon Credit & Purchasing Program


The Carbon Credit and Purchasing Program (C2P2) is an initiative to support colleges and universities in developing and marketing carbon offsets as a way to accelerate their progress towards campus carbon neutrality. Eligible schools can develop carbon credits on their campuses through energy conservation, energy efficiency, renewable energy, and LEED certified buildings. Proceeds from carbon sales are invested into sustainability projects on campus, allowing schools to achieve greater emissions reductions and pushing communities to develop clean, efficient energy systems. The Carbon Credit and Purchasing Program develops credits to the Verified Carbon Standard (VCS) through a methodology designed specifically for campus-based projects. As the manager of C2P2, Second Nature provides technical and logistical support to schools participating in the program.


C2P2 began as a continuation of Chevrolet’s Campus Clean Energy Campaign. Beginning in 2014 Chevrolet partnered with the U.S. Green Building Council, the Association for the Advancement of Sustainability in Higher Education, and 11 college and university campuses to launch the Campus Clean Energy Campaign. This Campaign provided funding to purchase and retire verified carbon reductions resulting from renewable energy and energy efficiency projects implemented at the participating campuses. These campus project credits were certified by VCS under a new VCS accredited methodology that the Climate Neutral Business Network developed in collaboration with stakeholders. This was part of Chevrolet’s Carbon Reduction Initiative, which reduced and retired 8 million metric tons of CO2 emissions, including the Campus Clean Energy Campaign credits. Due to the success of the Campaign, which ended in 2015, many participating campuses desired to continue verifying and marketing emissions reductions. This led to the development of Second Nature’s C2P2.


For the initial pilot phase of C2P2, Second Nature partnered with the Climate Neutral Business Network and six participating schools within the Climate Leadership Network.


The goal of C2P2 is to help leading institutions of higher education access finance from the voluntary carbon market as a way to fund deeper emissions reductions on their campuses. All proceeds from the sale of carbon credits must be reinvested into sustainability projects on campus. As such, C2P2 accelerates progress towards campus carbon neutrality. All participating schools must be signatories of Second Nature’s Carbon Commitment or Climate Commitment; through C2P2 these schools can reach their carbon neutrality goals and interim targets at a faster rate.


As the manager of C2P2, Second Nature provides technical and logistical support to schools participating in the program. This includes:

  • Assisting schools in completing VCS required project documentation.
  • Processing all projects through our Carbon Registry account.
  • Securing and contracting with third party validators and verifiers.
  • Acting as Seller Agent for participating campuses when they wish to sell carbon credits.

How to get involved

Selling Offsets

There are two paths that schools can take to participate in C2P2 under the VCS methodology:

  1. Campus-wide Performance
  2. Individual LEED Certified Buildings

Second Nature is currently focusing the expansion of C2P2 in New England, although schools from other regions are welcome to participate as well.  If you are interested in participating in C2P2, please e-mail
