Summary of Role & Key Responsibilities

We are looking for a Principal Consultant / Associate Director to join our Climate & Nature business line. The candidate will be primarily working for the Energy Transition service line, but it will also support the Climate Risk & Resilience and Green House Gas accounting service lines. The Energy Transition service line delivers unique projects that require quick, innovative and practical solutions. The work is divided into three pillars: industrial decarbonisation, technical due diligence and mandatory energy reporting. You will be responsible for the development and delivery of strategic, technical, and regulatory advisory services that support industrial clients in reducing carbon emissions and improving energy performance. The role focuses on securing new work, developing compelling decarbonisation and compliance solutions, and building senior client relationships across industrial sectors, but also overseeing high quality delivery, guiding clients on carbon reduction and regulatory requirements, and driving revenue through opportunity development, proposal leadership, and strategic advisory. It requires combining deep technical expertise with strong commercial leadership to drive complex projects, influence senior stakeholders, and shape clients’ long term decarbonisation pathways. This is a flexible hybrid role that can be based out of any of our UK offices.

Key Responsibilities
