What is Government doing to encourage us?
Are they placing a major prohibitive tax/tariffs on goods from China? No, because international Trade agreements work both ways.
Are they placing a major prohibitive tax on 4x4s and similar being purchased for use in urban areas? Don't think so.
Are they subsidising Public Transport to make it far more economical to use it rather than drive? Not that I know of.
Are they placing a levy on general waste bins, and say giving a refund of Council tax for the number of Green and other recycling bins used/collected? Don't think so.
Are they placing a major prohibitive tax on air and cruise travel? Not that I know of.
I am sure you can add to the list. I understand that some will say we don't need direction/incentives we should just voluntarily do it. That doesn't work in my view. Those who want to will, those who can afford to or can't be bothered will ignore it.
I do a lot of this voluntarily. No car, no kids, very little food waste, sensible use of heating, washing only when necessary and not out of habit after every wear/use apart from underwear, minimal plastic use when I can, grow salad stuff and have a small veg patch (not always a success but I try!), and so on. I am not religious about it, but I try to be mindful.
