The UK Treasury's proposed landfill tax on stabilisers used for decontaminating waterways is raising alarms among ministers and industry leaders. Set to take effect in April 2024, the tax could render crucial industrial projects financially unviable, risking job losses in coastal communities. The British Ports Association (BPA) has expressed concerns that this tax will hinder the clean-up of contaminated waterways and exacerbate flooding risks. A report from research firm Oxera warns that capital project costs may rise significantly, impacting the maritime sector, which supports thousands of jobs and contributes billions to the economy. In response, the BPA has urged Dan Tomlinson, the exchequer secretary to the Treasury, to reconsider this decision, emphasizing the potential economic and environmental harm. While the Treasury defends the tax as a necessary measure to address hazardous waste disposal, it acknowledges that only a small fraction of dredged material will be affected, assuring that businesses will have time to adapt before the tax is implemented.
