Overview
Sustainable Energy First (SEFirst) provides sustainability services for large organizations, helping them decarbonize and switch to renewable energy. It works by analyzing client data to identify decarbonization opportunities (data enrichment), then securing renewable energy contracts and managing the related projects through long-term procurement arrangements. A dedicated team of 154 sustainability changemakers delivers tailored consulting and project management to implement these solutions. SEFirst differentiates itself by combining data-driven identification of decarbonization projects with end-to-end energy procurement and project execution, focusing on UK-based businesses and other regions as needed. The company’s stated goal is to reduce its clients’ carbon footprints and achieve a reduction of 327,170 tonnes of CO2e by 2028, signaling a concrete environmental target and accountability.
