Transitioning of the Chemical Industry Toward a Net‐Zero Carbon Dioxide Emission Path
Angewandte Chemie, EarlyView.One way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.
