For a successful transition to net zero, we need both to propel forward innovative, scalable, decarbonising technologies and to ensure that they are sustainable throughout the supply chain. The University of Cambridge Institute for Sustainability Leadership (CISL) Accelerator is uniquely positioned to foster competitive, sustainability-led, growth-driven companies. This programme is designed for scaling up companies with novel technology-based products that have rapid market adoption and high impact potential for the net zero transition. The priority technology areas are renewable energy generation, distribution, storage, demand reduction, efficiency and electrification of energy use.
