Criticism of Green Levies?

There has been some debate over whether these taxes would be progressive or regressive if imposed. While this is not the intention, consumption taxes may accidentally harm the poor by causing them to save less of their income and consume more. According to research by the Joseph Rowntree Foundation and Policy Studies, flat taxes would have a disproportionate impact on poorer households.
Green levies are criticized by some as “silent taxes” that harm customers by raising car prices while doing nothing to reduce emissions. Critics argue that these taxes allow businesses and the wealthy to buy their way out of the consequences of their actions, while the poor, who are disproportionately affected by climate change, cannot.
