Together we can cut 300 million metric tons of CO2.

As a company, our vision is to bring our RDR technology, world leaders and industry leaders together to meet the biggest challenge our world has ever faced – the urgent need to drastically reduce CO2 emissions.

Bringing the world together to cut CO2

Our RDR technology combines rocket science, technical engineering and chemistry to turn one of the world’s most polluting processes into one of the cleanest. It is the only technology able to replace polluting, fossil-fuel powered steam crackers with an electrical solution that powered by wind and solar energy. By doing so, it literally has the power to cut CO2 emissions on one the most massive scales ever before seen.

But only if the world comes together to use it.

By sharing our RDR technology with the European Union, governments across the globe, and the world’s leading Ethylene producers, together we can cut CO2 emissions by 35 million metric tons a year by 2030 and 300 million metric tons by 2035. That’s an ambitious goal to say the least. But it’s a goal we must meet in order to ensure a future that’s sustainable for us all.


35 MMt elimination of annual CO2 emissions in the EU by 2030.


300 MMt elimination target of annual global CO2 emissions by 2035.
