Mantle Climate

What Mantle Climate does

Mantle Climate Corp. is a Canadian professional-services consultancy specializing in climate strategy and risk management for the built environment. Founded in 2015 by Ryan Zizzo (originally as Mantle, restructured via the 2021 Mantle Developments spin-off and subsequent rebrand to Mantle Climate), the firm is headquartered in Toronto with additional staff in Montreal and British Columbia and a total team of approximately 14 people. It sells three integrated service lines—Sustainable Design & Construction Advisory (embodied-carbon assessments, whole-building life cycle assessments, environmental product declarations, and certifications including LEED, Zero Carbon Building Standard, Green Globes, and municipal green standards); Climate Risk & Resilience Planning (asset- and portfolio-level climate risk assessments and adaptation strategy implementation); and Strategy & Climate Disclosure (corporate emissions inventories, SBTi-aligned target-setting, transition plans, and reporting into CDP, GRESB, and EcoVadis)—primarily to real estate developers, material manufacturers (concrete, steel, mass timber), governments, and industry associations.

The firm's underlying capability stack rests on deep technical expertise in life cycle assessment, climate science translation, and building certifications rather than proprietary software. Mantle's staff hold credentials (professional engineers, LEED AP BD+C, Fitwel Ambassador, PMP) and leadership seats on Canadian standards bodies including Carbon Leadership Forum, Canada Green Building Council, National Research Council Canada's LCA2 initiative, Canadian Board for Harmonized Construction Codes, CSA Group, and iMasons. Pricing is project-based/quote-based with no public rate card; client acquisition runs through direct enterprise engagement, thought leadership content, conference speaking, and industry-association referrals. Revenue is generated through professional-services fees on engagements such as Steelcon's 49% embodied-carbon reduction and first EPD, Toronto's North-American-first embodied-carbon cap (Toronto Green Standard v4), YMCA GTA's Climate Resilience Centres, and joint research such as the 2025 MaRS-led Future of Data Centres in the GTHA and Ontario study.
