The Greenhouse Gas Management Institute is USA-based a 501(c)(3) non-profit organization, also with a registered non-profit organization based in Italy.

Our Mission

“To address climate change by building and supporting a global community of experts  and institutions with the highest standards of professional practice in measuring, accounting for, auditing, and managing greenhouse gas emissions; meeting the needs of governments, corporations and organizations large and small.”

Our work involves educating on the basics of GHG accounting, auditing and management, training professionals to meet the highest standards of expertise and ethical conduct, and conducting forward-looking research into critical GHG measurement, reporting, and verification (MRV) issues.

Addressing climate change will require fundamental societal, organizational and behavioral changes on a global scale. The GHG Management Institute’s contribution to this effort is through the construction of the long-term social infrastructure needed to support the implementation of climate change policies, including professionalization of the field of GHG management and accounting. Professionalization occurs when an entire class of people make GHG management and accounting part of their professional identify. We believe this professionalization will be a powerful force to help us combat climate change.

We also believe that it is vital that the population of professionals with the expertise to address GHG emissions is globally widespread. Climate change is a global problem that requires a global solution. We offer financial assistance to other non-profits world-wide, to public agencies, and to small and medium-sized enterprises in developing countries. We welcome grants and contributions to further this mission and to sponsor scholarships. We are also collaborating with other organizations in various regions of the world to provide training in other languages and in ways that address local conditions.

The Institute offers online courses, which can be combined with face-to-face workshops for larger groups with specific needs. E-Learning allows learners a higher quality training experience, access to the world’s top experts as instructors, and the flexibility to undergo training on your own time, without the cost, trouble, and GHG emissions associated with traveling to workshops.

Our Values


Working honestly involves truth and transparency in all we do.


Working with integrity involves treating others as we would want to be treated ourselves.


Working responsibly includes serving others and our environment for good purposes.

Black lives matter: 

Climate change is a problem that demands global collective action; systemic racism and racial bias are barriers to a sustainable future.


We value the people we serve and strive to ensure timeliness and fairness in our dealings with all our members and stakeholders.


Within a new field such as greenhouse gas management, there is a significant risk that individuals will offer services without the necessary competence. We value educational and practical rigor, seeking to ensure that the professional community is equipped to deliver services at an ever-increasing level of quality.


One organization cannot ‘do it all’. We value working with others to create and share solutions for the betterment of the community at large.


We are committed to providing principle-centered leadership to the community of greenhouse gas professionals.

Individual and organizational potential:

We value the potential that exists within each individual and within each organization. As such, we commit to fostering the potential in others.
