Limiting global warming to 1.5°C implies reaching net zero CO2 emissions in 2050 according to the IPCC. Next to substantially reducing emissions, this target will only be possible by globally deploying carbon removal at the scale of billions of tons of CO2. Neustark is a leading provider in this rapidly growing field, having developed a solution to durably store CO2 from the air in recycled mineral waste such as demolished concrete. Founded in 2019 in Switzerland, our first solutions have been deployed in Europe and are already capturing and storing tons of CO2 every day. We are currently scaling up our operations and carbon removal impact globally – on the road to removing hundreds of thousands of tonnes of CO2 this decade – and millions in the decades to come.
