About Aj Mesiti

I turn net zero intent into engineered outcomes. I build the governance, capital allocation, and pilot-to-scale mechanisms that keep decarbonization programs funded and moving. I translate carbon math into decision-grade tradeoffs leaders can act on. I help programs survive growth, budget cycles, and competing priorities.Most recently at Amazon, I led $100M+/year in portfolio decarbonization across 1,500+ facilities. I built a 15-year net-zero glidepath and a stage-gate operating rhythm, using cost-per-ton prioritization to make carbon tradeoffs visible and decisions repeatable.What I do best- Portfolio governance (decision rights, stage gates, QBR cadence)- Net-zero roadmaps (glidepaths, growth modeling, abatement gap analysis)- Prioritization and capital allocation (cost-per-ton + ROI thresholds)- Adoption playbooks that turn pilots into standards (procurement + execution)Scope and stakeholders: Real Estate, Facilities, Finance, Procurement, Architecture/Engineering, and operations.Core tools: GHG Protocol (Scopes 1–3), SBTi alignment, abatement modeling, low-carbon materials and electrification, ASHRAE audits, ENERGY STAR / Portfolio Manager benchmarking.Brooklyn, NY.
