AJ Mesiti, MS

Sustainability program leader with 15+ years’ experience shaping and scaling carbon-reduction strategies across global logistics and real estate portfolios. At Amazon, I partner with cross-functional and operations leaders to advance decarbonization strategy for one of the largest building networks in North America—shaping nine-figure sustainability investment programs and embedding carbon considerations into financial and construction workflows. I focus on: Carbon strategy and accounting: Co-develop marginal abatement cost curves (MACCs) and glidepaths to inform multi-year planning, leveraging AI-driven carbon intelligence tools to identify opportunities within the buildings portfolio. Low-carbon materials & construction: Advance the use of innovative materials and supplier transparency standards across new-builds and retrofits. Operational carbon reduction: Drive programs in HVAC electrification, energy efficiency, and equipment decarbonization. Governance mechanisms: Collaborate on enterprise systems for investment approvals, implementation tracking, and carbon-impact verification, now in use across senior-level organizations. Team leadership: Manage and mentor program managers and operations leaders to expand their scope, improve technical writing, and deliver on decarbonization goals. Cross-functional leadership: Build partnerships across engineering, finance, and operations to align sustainability with growth and ROI. I’m passionate about making net-zero carbon pathways practical and scalable—turning complex technical, financial, and organizational challenges into strategies that deliver lasting business and climate impact.
