What We Do

Evergreen Carbon is a carbon offset portfolio management company. We provide high quality and value carbon credits to businesses and organizations who are seeking to mitigate their unavoidable greenhouse gas (GHG) emissions. We offers a wide array of carbon credits from projects located in the United States and throughout the world. We strive to offer projects that support local communities as they offset carbon emissions. 

Our goal is to help our clients create an offset project portfolio that reflects your values, ethics, industry sector, and geography. We can procure carbon credits from one project, or we can develop a portfolio of multiple projects that meets your organization’s requirements.

We can help you procure a meaningful carbon offset portfolio and communicate its value to your employees, shareholders, and the public.

Wolf Lichtenstein


The driving force behind Evergreen Carbon is Wolf Lichtenstein. Wolf has had a variety of technical, managerial and customer-focused roles throughout his almost 30 year-long career. Making a commitment to follow his own passions and professional aspirations, Wolf formed Lightstone Consulting, LLC in 2005. Lightstone Consulting is an environmental consulting practice that blends expertise in Greenhouse Gas (GHG) accounting, and Environmental Management Systems, organizational change and sustainability management practices. Once he found his enthusiasm and excitement about the confluence of technology, ecology and human systems, starting up Evergreen Carbon was the next natural step – promoting the many wonderful sustainable development aspects of Carbon Offset Projects.
