Scope 3 Is a Supply Chain Problem, Not an Excuse

Scope 3 emissions — everything upstream and downstream of the building itself — are routinely treated as someone else's problem. Three Indonesian developers proved otherwise using contracts they already had.

The biggest carbon cut in the project was written into a contract, not a wall.

By specifying low-carbon cement and requiring supplier disclosure as a condition of payment, they cut embodied carbon by double digits without a single design change.

We share the contract templates because the barrier is rarely technical. It is the assumption that procurement language cannot carry climate intent. It can.
