About Nathan Alexander

I turn sustainability ambition into measurable outcomes; cutting emissions, strengthening resilience, and de‑risking capital programs. At GHD, I partner with public agencies and operators across U.S. ports & ferries, transportation, and energy to design roadmaps, deliver pilots, and scale implementation under real‑world constraints.How I work- Decarbonization pathways aligned with IIJA/IRA funding, with scenario modeling, CAPEX/OPEX trade‑offs, and performance tracking for U.S. infrastructure portfolios- Climate risk & resilience strategies that translate physical and transition risk into clear adaptation measures for agencies navigating federal guidance (NEPA, PROTECT, Justice40)- Governance & assurance, as an ENV SP and EMS Lead Auditor, embedding ISO‑aligned processes that withstand regulatory, investor, and community scrutiny; built for U.S. asset owners and operators.Proof points- Led zero‑emissions mobility and fleet electrification planning with phased vehicle transition, utility coordination, and charging infrastructure integration for public agencies- Built audit‑ready sustainability frameworks and metrics architectures to support decarbonization, electrification, and climate resilience programs across U.S. and international clients.If you’re moving from intent to implementation on net zero, electrification, resilience, circularity, or climate adaptation, let’s connect. I bring a hands‑on, evidence‑based, outcome‑focused approach grounded in U.S. policy, funding, and infrastructure realities.
