At the TaxPayers' Alliance, we've just released a new calculator that allows people to work out the amount they're paying in green taxes and regulations. With the effects of so many taxes and regulations, like the Renewables Obligation and European Union Emissions Trading Scheme, hidden in prices hopefully this tool will shed some light on them and stop a political race to ever stealthier ways of imposing big costs on the public for policies that do little to achieve their stated objectives.
If you have a website of your own, there are lots of options to let other people know what they're paying. You can link to the calculator with text or an image, embed the calculator itself on your site, or embed or link to your own results. Those options are all available from the calculator's results page.
