FAQ

Frequently asked questions

How do I start the membership process?

Select Join Now to open the membership registration page. Choose a tier, provide your contact and billing information, and continue to payment there.

Does membership change access to EC3's core tools?

No. The EPD Repository, Find & Compare Materials (including Pilot Categories), Project Planner, and Declare Your Product remain free and open to everyone, member or not.

Can I add more seats to my organization's membership?

Community and Practitioner tiers can add seats for $250/year each. Sustaining tier includes unlimited seats.

Is a discount available for nonprofits or government agencies?

Indicate eligibility when completing the membership registration page.

How is the Sustaining tier priced?

Sustaining members self-select their annual dues within the $10,000–$25,000 range, based on their capacity to support BT's mission.

Does membership come with voting rights or a seat on the Board?

No. EC3 Membership is a non-voting membership class. It doesn't confer governance rights, Board representation, or a vote on BT decisions.

Is my membership dues payment tax-deductible?

Membership dues are treated as general program revenue. A fair market value (FMV) analysis and donation acknowledgement letter are available upon request. We recommend checking with your own tax advisor.

I already give as a supporter/donor — do I need to become a Member too?

No. Membership and Supporter giving are separate ways to engage with BT, and you're welcome to do either or both — whichever combination best fits how you want to support the organization.

My organization already has an Enterprise Instance — does membership replace that?

No. Membership is additive to any existing Enterprise Instance or fee-for-service agreement — it doesn't change or replace those arrangements.

Is membership billed annually, and does it auto-renew?

Yes — membership is billed annually and renews automatically unless you cancel at least 30 days before your renewal date.

Can I upgrade or downgrade my tier?

Yes. You can upgrade to a higher tier at any time, with the difference prorated for the rest of your term. Downgrades take effect at your next renewal.

How do I pay?

Payment is completed on the Join EC3 registration page after you select a membership tier and enter your information.

My organization doesn't cleanly fit one of the tiers — can we talk about a custom arrangement?

Yes — reach out to membership@buildingtransparency.org and we'll work with you to find the right fit.
