New suppliers get access to free footprint calculators; existing data is pre-populated automatically.
3
Validate
Every submission passes automated checks and human review from our carbon accounting team.
4
Act
Suppliers set science-aligned targets, build a decarbonization pathway, and move into collaborative reduction, all tracked on a live, shareable profile.
From supplier outreach to measurable progress
A smarter approach to supplier engagement, tailored to where each supplier actually is.
Meet suppliers where they are
Understand supplier maturity and existing emissions data first so engagement can start from what’s already known.
Get verified audit-ready data
Every submission is validated and feeds straight into your Scope 3 calculations.
Collaborate on real reduction
Suppliers set targets and act on initiatives, not just report numbers.
Scale without hiring
Green Project manages supplier outreach, follow-up, and communications so you can engage at scale without adding headcount.
Turn supplier data into a practical reduction plan
Knowing your footprint is only the starting point.
Green Project’s AI-powered Decarbonization Agent uses each supplier’s emissions profile to identify the actions most relevant to their business.
Suppliers receive personalized recommendations from a library of 750+ initiatives with estimated impact and cost guidance to help them build the business case and move from measurement to action.

Turning Measurement into Action
Learn how ACT Group is turning emissions data into action to decarbonize its own operations and supply chain.
"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."

More on Supply Chain Engagement
Blogs, insights, and updates on engaging your supply chain at scale.
What is supply chain engagement for Scope 3 emissions?
Supply chain engagement is the process of working with suppliers to measure, verify, and reduce emissions across your value chain. Green Project helps companies assess supplier maturity, collect supplier-specific emissions data, validate submissions, set targets, and collaborate on decarbonization initiatives.
How does Green Project help me act on product data?
Verified PCF data flows straight into your Scope 3 reporting, so you can see emissions by product and product line instead of relying on spend-based estimates. From there, Green Project's Decarbonization Intelligence gives suppliers tailored recommendations and access to a library of vetted reduction initiatives they can act on directly, and Renewable Energy Procurement gives them a route to cut emissions through EACs. You get visibility into hotspots and progress; your suppliers get a clear path to actually reduce them.
Do I need an existing supplier engagement program or team to get started?
Campaigns are fully managed by our experts, so you can start from zero, without hiring or having a program in place already.
How do you engage suppliers that haven’t measured their emissions yet?
Green Project meets suppliers at their current level of carbon accounting maturity. Suppliers without emissions data can use free footprint calculators to get started, while suppliers with existing data can build on what they have already measured and reported.
How is supplier emissions data verified?
Supplier submissions go through automated checks and human review by Green Project’s carbon accounting team before reaching your Scope 3 accounts, helping ensure the data you report can stand up to scrutiny.
What supplier emissions data can Green Project collect?
Green Project supports supplier-specific data including corporate carbon footprints (CCFs), product carbon footprints (PCFs), and service carbon footprints (SCFs), helping improve Scope 3 calculations and reduce reliance on industry averages and spend-based estimates.
