Become a Partner
Support our mission and help drive further development of EC3.
Why Partner With Us
Building Transparency relies on our implementation & technology partners to advance our mission and expand the real-world impact of EC3. When users search EC3, they’re not just accessing a dataset—they are drawing on shared public infrastructure that requires ongoing stewardship. Each query is supported by a combination of advanced automation and human expertise, including parsing imperfect real-world EPDs, validating and correcting data, managing versions and duplicates, interpreting GWP so comparisons are meaningful, maintaining expert-informed category structures, and operating secure, reliable infrastructure to SOC 2 standards.
EC3 works because it is stewarded as a public good and supported by a global community committed to data-led climate action. We offer multiple partnership pathways depending on your role, goals, and needs.Â
Looking for increased API rate limits, expanded Project Planner capacity, or member convenings? Those are now offered through EC3 Membership.
Industry Partnership
Industry partners, such as trade associations, manufacturers, and program operators, work with our team to develop and refine EC3 material categories, for example by advising on EPD data quality within a category. Partner input is advisory; Building Transparency retains sole discretion over EC3 data, categories, standards, and roadmap.
EC3 Enterprise Partnership
An EC3 Enterprise Partnership is a fee-for-service arrangement for organizations that need custom EC3 functionality, data integration, and dedicated support. Enterprise Partnerships are separate from EC3 Membership. Services include:
Individual hosted instance of the EC3 tool on a dedicated server of their choosing
Dedicated Online & Biweekly User Support for multiple user groups within and outside of the Enterprise Partner company, as needed
Custom Branding, Login, User Interface & Workflow
Portfolio Level Tracking & Reporting
Looking for EC3 API Access?
The free, rate-limited EC3 API remains open to everyone. Increased API rate limits are now included with EC3 Practitioner and Sustaining Membership. If your organization has an existing EC3 API Data Order, it remains in effect through its current term, and our team will reach out about how membership fits.
Other Fee-for-Service Partnerships
Does your organization need more hands-on support in using EC3? Would you like our team to provide an educational workshop on using Building Transparency tools? We recommend starting with our user guide, but you can also request a hands-on virtual session with our team.
One-on-One Advisory Sessions ($500/hour; $450/hour for EC3 Members): One-hour sessions with BT staff to discuss sector data, EC3 roadmap questions, help using EC3 tools and workflows, and general embodied carbon strategy. Sessions are advisory only and non-binding on Building Transparency, confer no preferential business relationship, and do not include procurement recommendations, product endorsements, or compliance advice.
EC3 Training Sessions ($600/hour; $540/hour for EC3 Members): Private EC3 training tailored to your organization’s needs. Customized trainings may require up to five hours of preparation and delivery.
EC3 Members receive a 10% discount on advisory and training sessions. All sessions are scheduled as BT staff capacity allows.
