This proposal outlines a strategic partnership between Mattamy Homes and GreenCheck to launch a Green Supply Chain (GSC) Pilot, supporting Mattamy’s leadership in embedding ESG principles into procurement and supplier/contractor engagement.

The GSC pilot addresses three key challenges:

1. Knowledge Gaps - Many contractors and subtrades lack training on ESG standards, reporting, and best practices, limiting field-level execution of corporate goals.
2. Verification Gaps - ESG commitments often remain unvalidated at the corporate and jobsite levels, reducing confidence in reported performance.
3. Embodied Carbon Data Gaps - there is a need to collect upfront carbon data from 'construction and process' stage, while laying the foundation for future integration of 'product'-stage emissions tied to manufacturing and transport.

GreenCheck provides a scalable, data-verified platform combining contractor accreditation, training, centralized tracking, and embodied carbon data collection - enabling Mattamy to embed measurable environmental performance into operations today, while preparing for future full life-cycle carbon reporting
