CDP is a global non-profit that runs the world’s only independent environmental disclosure system. As the founder of environmental reporting, we believe in transparency and the power of data to drive change. Partnering with leaders in enterprise, capital, policy and science, we surface the information needed to enable Earth-positive decisions. We helped more than 24,800 companies and almost 1,000 cities, states and regions disclose their environmental impacts in 2024. Financial institutions with more than a quarter of the world’s institutional assets use CDP data to help inform investment and lending decisions. Aligned with the ISSB’s climate standard, IFRS S2, as its foundational baseline, CDP integrates best-practice reporting standards and frameworks in one place. Our team is truly global, united by our shared desire to build a world where people, planet and profit are truly balanced. Visit cdp.net or follow us @CDP to find out more.

H2C is committed to accelerating the hydrogen economy by providing a breakthrough in the transportation and infrastructure required to bring green hydrogen to market now at a price that is competitive with fossil fuel. H2C’s goal in commercializing these technologies is to provide the safest, most flexible, most cost-efficient, and most rapidly scalable way to transport pure hydrogen in large volumes from locations where hydrogen can be produced at the lowest cost, to the markets and end-users where clean energy is in greatest demand. In this way, H2C is helping to enable and accelerate a transition to the hydrogen economy as a critical component to addressing global climate change. H2C provides an end-to-end hydrogen delivery infrastructure solution comprised of three major components. H2C Safety Pipe™ - H2C’s patented Pipe-within-a-Pipe™ technology provides middle and last-mile distribution for gaseous hydrogen using existing rights-of-way and avoids stranded pipeline assets, while mitigating the environmental and safety risks of hydrogen leakage through dual-containment and 24/7/365 monitoring and control. H2C Pipeline in the Sky™ - H2C’s proprietary H2 Clipper™ airship will enable long-haul transport for 125-200 tonnes of liquid hydrogen across thousands of miles at less than the cost of conventional ships at sea, and on the return trip be able to deliver traditional cargo at a fraction of the cost of traditional air freighters... 100% carbon-free. H2C Hydrogen Depots - H2C’s proprietary hydrogen depots will interconnect these two components, creating an end-to-end infrastructure serving demands for both liquid and gaseous hydrogen as clean renewables-based energy at a price point that is competitive with todays cost of fossil fuels.
