KOMMA5 ° offers all owners of electric vehicles free electricity, which we refinance through trading with so-called GHG quotas. 1KOMMA5 ° encourages to lead a self-determined and CO2-neutral life.

At 2150 we back mission driven tech entrepreneurs who are solving some of the largest problems facing the planet today. We focus on the full stack of the urban environment where most of the world's CO2 emissions and resource waste is arising and which will double in the next decades.

Aeroseal’s mission is to revolutionize the way buildings consume energy, drastically reducing their carbon emissions in a simple, safe, and cost-effective way. How will we do it? With our air-sealing technologies. Small leaks are a BIG problem -- The ducts and walls in buildings leak air - wasting energy and affecting comfort, and traditional sealing solutions fall short of solving the problem. Aeroseal’s technologies - HomeSeal Connect, SmartSeal, and AeroBarrier Connect - inject a fog of sealant particles into these pressurized spaces, efficiently sealing air leaks in both ducts and the building envelope. Software tracks the entire process, creating a certificate of completion showing before and after leakage. Aeroseal is one of the fastest-growing clean technology companies in the U.S. and has sealed over 250,000 buildings globally, spanning homes, hospitals, schools, government facilities, hotels, and offices. This commitment has resulted in billions of dollars in energy savings.

Blue Frontier has developed a truly smart air conditioning system. We change the concentration of a salt-solution to create cooling with minimal energy requirements. This means that the air conditioner will require less than half the electricity than a conventional system. Also, our A/C does not have to consume electricity when its working, allowing us to move electricity consumption to non-peak periods, when electricity is cheapest and produced by renewable energy. While saving energy is critical, we are also a better A/C. With our system we can decouple humidity control form air temperature control, a feat difficult to accomplish with your conventional A/C technology. This, coupled with smart distributed control systems, ensures that your and all our customers will never feel too hot or too cold, but just right all the time.

CarbonCure Technologies creates, develops, and licenses solutions that consume waste CO2 to make better concrete. It spurs the market shift towards affordable green concrete, by enabling concrete manufacturers to convert waste CO2 into solid minerals, locked away as a solid within concrete during manufacturing. It is a green building technology company currently serving concrete product manufacturers in the US and Canada. It offers concrete producers the ability to manufacture green concrete products without compromising on either quality or price. CarbonCure is a retrofit innovation that repurposes CO2 gas from large final emitters as a feedstock in concrete plants. The gas is permanently converted into embedded solid mineral carbonates that yield material, environmental, and production advantages. By enabling concrete manufacturers to consume CO2 into concrete products during manufacturing, the technology differentiates an otherwise traditional commodity concrete product, while achieving superior material performance characteristics. In addition to technology, CarbonCure provides demand-pull marketing and environmental reporting/certification services to reinforce its customers’ exclusive competitive positioning. The technology is licensed at a very low-CAPEX to concrete producers, generating a recurring revenue stream. CarbonCure Technologies was founded in 2007 and is headquartered in Halifax, Nova Scotia.

Kelvin was founded in New York City in 2013 by Marshall Cox, a material science engineer with a Masters from Cornell University and a PhD in electrical engineering from Columbia University. The inspiration for the company came from Marshal’s twin brother, who complained about the heat in his apartment while staying with him for a month. Marshal came up with a solution that eventually became the basis of Radiator Labs, the original name of the company. Unknowingly, from that day forward, he set out on a mission to decarbonize legacy building’s heating and cooling systems. After conducting several successful pilots, Radiator Labs launched a full-scale commercial deployment of the Cozy system in 2016. The Cozy is a retrofit device that encloses radiators and controls their heat output. Radiator Labs participated in studies with NYSERDA and Con Edison, consistently demonstrating savings on heating bills between 25% and 40% with the Cozy system.
