we are lawyers, engineers, business consultants and financial professionals

Mantle314 is a boutique consulting firm with over 60 years of combined experience in climate work. Our mission is to shine the light on climate-related risk and opportunity and advance strategies to thrive. Our unique approach stems from our team’s hands-on experience with a wide range of industries, including finance and construction, on climate solutions.

We develop future-focused solutions aligned with business and strategy goals including staff and board climate education, climate-related policy research, guided facilitation of climate strategy and intelligence gathering, and climate policy development and implementation.

We work with leading tools and systems to accomplish this, including both climate governance/disclosure frameworks like the Task Force for Climate-Related Financial Disclosures (TCFD) and construction and operational green building tools like LEED and zero carbon building standards.

Our multi-disciplinary team bridges the gap between global climate best practices and decision-useful business strategies, informed by a broad range of perspectives and experience.
