Negative Carbon Emissions?

The Drax electricity-generating station in Yorkshire used to be a major burner of coal. Thankfully, the plant no longer uses coal and has switched to using wood pellets (https://www.theguardian.com/business/2021/mar/23/green-groups-dispute-power-station-claim-biomass-carbon-neutral). The switch from coal to wood at Drax, was only realised by the injection of some £800m of government subsidies etc. A number of environmental organisations (including Friends of the Earth and Greenpeace) have, however, challenged the Drax operator's claim their plant provides 'negative carbon emissions'. Trees incorporate carbon dioxide into wood. That carbon dioxide is 'liberated' from the biomass, by burning and could be subject to carbon capture. The use of this biomass is not, however, strictly carbon neutral. The wood has to be collected, processed and transported to Drax. The station's carbon footprint will be substantially larger, if they, due to shortages, have to import wood from Canada to burn. Biomass does little to reduce the levels of atmospheric carbon dioxide. It's basically gas in, gas out (with more out than in). It would be better to increase the use of renewables in electricity generation.
