I doubt the price of petrol, diesel, gas will ever come down in price again sadly due to the de-carbonisation of those industries, The UK's ETS (Emissions Trading System) is intertwined with the EU's Fit for 55 meaning a 55% drop in emissions before 2030 (The UK's is actually 64%
) I'm not quite sure when the carbon pricing taxes start but they're talking about funding Free public transport with those taxes.
