Hear from our customers
"Working with Green Project was one of the most efficient processes that I’ve gone through. The attention to detail, the communication speed, the proactivity — making sure I can follow the process alongside them. As a business owner, it made my life simpler."
"At Microsoft, we believe that technology can be a powerful force for good. Our collaboration with Green Project Technologies is a testament to that belief and our commitment to small & medium suppliers."
"With the support of the Green Project Team, we hit 100% participation, and the renewable energy purchased added up to 10,300 MWh...That’s enough to power 890 American homes for a year. It’s a significant amount that we’ve achieved in year one. We’re very pleased with the outcome."
"Even if you don’t have an immediate need, think about getting started. Because in the end, with the right partner like Green Project — this is not a journey that can be taken alone — the process was easy, and it really got us to a better place."
"Green Project''s platform has helped us understand restaurant-specific & scope-specific emissions, enabling us to focus on reduction efforts that will have the greatest impact."
"They were instrumental in guiding us through the development of our GHG inventory, and the creation of a ‘starting point’ to enable us to set goals and track our progress against them. We’re grateful to Green Project and proud to have them on this journey with us."
"Their expertise and collaboration have not only improved the accuracy of our inventory year-over-year, but were also instrumental in the successful submission and eventual validation of our near-term Science-Based Targets. This work is a key part of Fortinet’s broader climate strategy and our commitment to building a more secure, sustainable digital future."
"With Green Project, we are able to highlight areas for supplier improvement right in the platform, send that information to our suppliers and receive comments back directly in the platform. Green Project has helped us centralize and seamlessly report our Scope 3 emissions and build strong relationships with our supply chain partners."
"Working with the Green Project team was smooth and straightforward. This was our first time reporting on sustainability initiatives, and Green Project made the process simple. They provided everything I needed to ensure we stayed fully compliant with Microsoft’s requirements."
"Not only has Green Project helped us increase the accuracy of our inventory year-over-year, improve our CDP climate score, and shorten the third-party verification process, they have also made me feel like I have an extended team of experts to learn on, which has been a game changer as an ESG team of one."
"Green Project gave us a stronger understanding of our Scope 3 emissions and a practical way to engage suppliers. That means we're not just improving the quality of our reporting, we're building the foundation for more targeted decarbonization action."
"Our Green Project sustainability manager has been very supportive and helpful. Whenever we didn’t have a piece of information, she helped us figure it out and guided us through everything."

Frequently Asked Questions
Have more questions?
What solutions does Green Project provide?
Green Project covers the full range of what's needed to turn measurement into progress:
Measure (Corporate, Product and Service Carbon Footprinting)
Reduce (Supply Chain Engagement and Renewable Energy Procurement)
Plan (Supply Chain Analysis and Transition Planning)
Report (Reporting and Compliance)
What makes Green Project different from other platforms?
Most vendors cover one piece of the sustainability journey: carbon accounting or supplier engagement or renewable energy procurement. Green Project brings all of your needs into one platform, powered by AI-assisted tools that speed up validation and reporting. Use it as your end-to-end climate management platform, or start with a single solution and add the rest when you're ready.
Can I still use the solution if I don't already measure my emissions?
Yes. Green Project is designed to support organizations at any stage, whether you're just starting out or further along. Companies come in through whichever solution fits their most pressing need, and build out from there at their own pace.
What training does Green Project provide?
Green Project provides structured onboarding for both buyers and suppliers, with dedicated support teams guiding you through setup and beyond. Onboarding is tailored to where you're starting from, not a fixed template.
How do you ensure that supplier data is reliable enough to report on?
Every supplier submission goes through a two-layer review: automated checks for completeness and accuracy, followed by review by a Sustainability Manager who validates methodology and supporting evidence. Every score is aligned to the GHG Protocol's five data quality dimensions, so your data is built to hold up under audit.
Will I get support along the way?
Yes. Every customer works with a dedicated Sustainability Manager who sits on the same team as Green Project's carbon accounting experts. Our Sustainability Managers provide support at every stage of the process.
