I’ve always wondered why a broad-based carbon tax with 100% of the proceeds refunded to the populace is not a more common approach for attempting to address climate change. It seems like as long as you agree that climate change is a problem that needs to be addressed, you should be supportive of such a scheme. IMO, the simplest and most fair way would be to simply divide the revenue generated from such a tax and write a cheque to every adult in the country for the same amount. To ease the transition and allow people to be able to make meaningful changes to improve their carbon footprint, this tax could start lower but would have to ramp up to pretty significant levels in order to achieve the desired change across the population that it is being applied - ideally, globally.
Perhaps some people on the political left would be concerned that this could lead to situations where poor people struggle to maintain their current lifestyles - but the entire point of this is that they would be incentivized to shift to a lower carbon footprint lifestyle, not maintain a wasteful one. Poor people have lower carbon footprints than rich people, unsurprisingly, so such a scheme would still ultimately result in some net transfer of wealth from richer people to poorer people. But more importantly, the incentives would be there for everyone to reduce their carbon footprint, regardless of socio-economic class.
I am not sure what reasonable objections might exist on the political right - carbon taxes are one of the easiest ways to incentivize market-based solutions and are even supported by many large fossil fuel companies. Which is why it is bizarre to me that, for example, the Canadian Conservative party wants to go to a soft cap style system instead of sticking with a carbon tax.
The biggest challenge I see is it being a coordination problem between countries - if all countries applied this evenly, there would be no issue with companies being incentivized to leave to another country with lower carbon tax. I can see it being pretty tempting for developing countries to ask for lenience and allow for them to not have to have the taxes in order to allow them to catch up - but a lot of developing countries are also the ones that will be the worst affected by climate change, so it is really in their best interests to have a high carbon tax to ensure that all the first world countries maintain their carbon taxes at a high level as well. If developing countries had high carbon taxes, there would be zero excuse for any developed countries to not have them as well.
Is the issue that the general population simply doesn’t take climate change seriously enough to want to accept anything that could negatively affect them in the short term? There are certainly a few deniers left, but it seems like people across the political spectrum in most countries now acknowledge that climate change is a problem that needs to be addressed. Perhaps, globally, we are only at a point where people are willing to talk the talk but not walk the walk.
