Hear from our customers
“Amazon.com engaged Sustas LLC to support the measurement and disclosure of our annual carbon footprint. Their team’s expertise in GHG emissions accounting, assurance readiness, and ability to support the automation of reporting processes was a notable value add to our annual carbon footprint reporting cycle. In addition to providing hands-on support, they prepared materials that can be leveraged internally as we engage with business partners to continuously improve carbon accounting and reporting processes.”
“We had the pleasure of working with Stuart Block and Sustas last year after receiving numerous requests from our customers on our company’s ESG policy and GHG emissions footprint. This is something that we have always believed was critical but as a small team didn’t have the internal expertise or bandwidth to address appropriately. We engaged Sustas to help with “right-sizing” our company’s approach based on scale and customer demands. Stuart provided practical tools that we’ve been able to take to heart and implement across our team beyond just the finished product of our annual report. Sustas has helped us create a better culture around sustainability both internally and externally with our partners; we feel much better about our companies’ choices and have a much better understanding of the sustainability goals that we can achieve. It’s been much easier than we had expected, the little things really do add up. Stuart was a pleasure to work with; our entire team enjoyed the meetings with him. He is knowledgeable, competent and makes sustainability fun and practical.

“Sustas has been an invaluable partner to us in just a few short months of engagement. Stu and Ben’s detailed technical expertise in GHG Accounting, and experience with ESG reporting and strategy has allowed us to add further rigor and structure to our existing programs and better align ourselves with emerging regulatory and reporting trends. They are consummate professionals and great people; taking potentially dry subject matter and breaking it down through engaging conversations. They have helped us prioritize our efforts and focus on reasonable short- and long-term actions we can take to bolster our initiatives.”
