Dear Clients and Colleagues:

We are pleased to announce that we have purchased the Forestry Carbon and Greenhouse Gas Services division of Environmental Services, Inc.,  effective May 24, 2019.

For the past 14 years it has been our pleasure to serve you as consultants, validators and verifiers on your greenhouse gas emissions, offset, and removal projects around the world. We have worked on projects large and small with customers of all experience levels in our industry.

Through our constant desire to learn as well as educate, we have built a reputation around the World as thought leaders in the Carbon Sequestration, Validation, and Verification community. Now, we are excited for the opportunity to serve you via our new entity, Aster Global Environmental Solutions, Inc.

Our goal is to provide a seamless transition in services from ESI to Aster Global and to continue with the excellent customer service and scientific knowledge you have come to expect. Our team of scientists, foresters, biometricians, validators, and verifiers will remain largely unchanged. In most cases, the people you have worked with on your projects will remain the same. For most of our customers, very little will change and your projects will transfer with little to no impact. In the coming days, we will be contacting you individually to discuss your current and ongoing project needs and how we can best serve you through the transition in ownership.

Aster Global will continue to be accredited by the American National Standards Institute (ANSI) under ISO 14065:2013 for greenhouse gas validation and verification bodies including: ISO 14064-3:2006, ISO 14065:2013, validation/verification of assertions related to GHG emission reductions and removals at the project level for Land Use and Forestry (Group 3), and verification of assertions related to GHG emissions and removals at the organizational level (Group 1 – General, Group 2 – Manufacturing, Group 3 – Power Generation, Group 5 – Mining and Mineral Production, Group 6 – Metals Production, Group 7 chemical Production, Group 8 – Oil and Gas Extraction, production, and Refining including Petrochemicals, and Group 9 – Waste). We are also accredited by the California Air Resources Board.

Thank you for your continued trust. We look forward to serving you.
