The last UN Environment Emissions Gap Report warned that, in order to ensure global warming stays below 2°C, efforts should be tripled, and if we want to stay below 1.5°C, they should
CCU, Carbon Capture and Utilization, even better than biomass as a feedstock

And CCU chemicals may have a much lower footprint than bio-based
