About Deep Sky

Deep Sky is a pioneering company focused on building infrastructure to scale carbon dioxide (CO2) removal systems. Operating primarily in Quebec, the company leverages the region's abundant hydroelectric power, immense wind power potential, and rich geological makeup to facilitate its operations. Deep Sky's core service involves using direct capture machines to absorb CO2 molecules from ambient air and ocean water, which are then safely and permanently sequestered underground. This process aims to set a new benchmark for Scope 3 carbon removal, offering durable, scalable, and inherently measurable solutions to combat the climate crisis.

Deep Sky serves a diverse range of clients, including government bodies, local communities, and private sector companies looking to offset their carbon emissions. The company operates in the environmental and sustainability market, focusing on carbon capture and storage technologies. Its business model revolves around partnering with direct air and ocean carbon capture companies, as well as collaborating closely with government officials and local communities to ensure that its facilities are a collective effort built to serve the best interests of all stakeholders.

Revenue is generated through the sale of high-quality carbon emission offsets, which are durable, scalable, and verifiable. These offsets provide a tangible way for businesses and governments to meet their carbon reduction goals, thereby securing the next 150 years for humanity.
