The carbon balance also reveals a unique opportunity for the chemical industry to provide negative emissions, which may offset difficult to abate emissions in other sectors. Today's chemical processes mostly take carbon from the ground and release it to the atmosphere as emissions, creating a ground-to-air carbon vector (Figures 3C). However, the carbon cycle shows a possible route for inverting the carbon vector, to air-to-ground, by combining bio-based and DAC/CCU technologies with sequestration using CCS or landfill. This offers a new dual value proposition for the chemical industry: utility from chemical products and potentially an additional revenue stream from negative emissions. This unique path for the chemical industry adds significant value to society compared to e.g. DACCS without utilisation of the carbon atom.
