I will persist in believing that, if governments were serious about doing anything to combat climate change, they'd target for reduction some of the adverse impacts of climate, and either legislate appropriately, or put in place some incentives that would help mitigate those impacts. That they are not serious, can be clearly seen by the UK Government's Zero Emission Vehicle (ZEV) mandate, which...:
...sets out the percentage of new zero emission cars and vans manufacturers will be required to produce each year up to 2030. [Eighty] % of new cars and 70% of new vans sold in Great Britain will now be zero emission by 2030, increasing to 100% by 2035. Source
There are some loopholes, of course:
If a manufacturer fails to meet this target, it could be fined £15,000 per car it sells that’s outside the allowance. This is unlikely to happen, though, as there are several ways to avoid this. Non-compliant manufacturers can buy ‘credits’ from manufacturers that do comply, for example. Manufacturers that do comply can also ‘bank’ sales that can be traded in years where they may not comply. This system was introduced in 2023 as a part of the ban on fossil-fuel powered cars being pushed back from 2023 to 2035.

and subsidies to that fortunate part of the population that can afford to own cars and vans:
The government’s schemes to lower the upfront and running costs of owning an EV [Electric Vehicle] includes the plug-in van grant of up to £2,500 for small vans and £5,000 for large vans until at least 2025 and £350 off the cost of homeplace chargepoints for people living in flats.

This is the usual complex, faintly corrupt, totally ineffectual policy that, sadly, is the norm. It might do something to change the ratio of EVs to other vehicles, but it is guaranteed to do nothing positive for the climate. Our politicians are more concerned with placating large corporations (those that make, sell and service vehicles), and motorists; and, as in agriculture (just one example), continuing to transfer funds from the poor to the wealthy. At least there's some consistency: amidst the tax hikes announced in the UK's budget today, we read that:
Fuel duty stays frozen
Rates on fuel duty – a tax included in the price you pay for petrol, diesel and other fuels – will be kept the same in the next financial year. The temporary 5p per litre cut introduced in 2022 will remain for one more year. Autumn Budget 2024, 'Which? News' 30 October 2024
What would a meaningful attempt to combat climate change look like? First, we'd have some idea of what we want our policies to achieve. My thinking is that our goals would be expressed as an array of scientific, social and financial indicators of the climate and its impacts, each of which would have to fall within an approved range for a sustained period before they could be deemed achieved. What we have today is an exclusive focus on atmospheric composition. The plethora of policies supposedly aimed at influencing that over the years have had precisely zero effect:
