杂志R181于20世纪80年代进行，估计耗资150亿英镑。英国政府可持续发展委员会 (SDC) 估计，与新建燃气发电厂相比，该设施每年可减少 5.6 公吨二氧化碳。据 SDC 称，修建拦河坝的碳足迹将在 5 至 8 个月内收回。这一概念基于成熟的技术，法国北部兰斯河上的类似拦河坝自 1966 年以来一直成功运行。尽管这显然是避免碳排放的重要措施，但环保人士强烈反对卡迪夫-韦斯顿拦河坝的想法。它将确保目前潮汐沼泽地的大片地区将永久被水淹没，政府承认“一些生物多样性将会丧失”。为此，英国皇家鸟类保护协会（RSPB）对将大坝列入候选名单的决定提出了批评。
Magazine R181 conducted in the 1980s, is estimated to run to£ 15 billion. The UK government’s Sustainable Development Commission (SDC) estimates that this facility could save 5.6 Mt carbon dioxide per year, in comparison to new-built gas-fired power plants. The carbon footprint of building the barrage would be paid back in 5–8 months, according to the SDC. The concept is based on proven technology, as a similar barrage at the river Rance, in Northern France, has operated successfully since 1966. Even though this would clearly be a significant measure to avoid carbon emissions, environmentalists are up in arms against the idea of a Cardiff–Weston barrage. It would ensure that large areas that are currently tidal marshland would be permanently under water, and the government admits that “some of the biodiversity would be lost.” For this reason, the Royal Society for the Protection of Birds (RSPB) has criticised the decision to include the large barrage in the shortlist.
