Key Responsibilities:

Lead Whole Life Carbon (WLC) assessments for major projects, from early-stage feasibility through detailed design and delivery.
Develop and optimise project-specific carbon reduction strategies, advising on materials, construction methods, and design options.
Use One Click LCA to model, analyse, and report embodied and operational carbon, ensuring data quality and consistency.
Present clear, insightful WLC findings and recommendations to clients, design teams, and senior stakeholders.
