Sorry to be so negative but that's how I see it.
After 24 hours of frenetic political briefing, the prime minister held a hastily convened press conference at Downing Street to announce that the 2030 ban on the sale of petrol and diesel cars – and gas boilers – would be pushed back to 2035.
The EPL includes an investment incentive that means oil and gas firms can offset from their tax bill 91.40 pounds in every 100 pounds spent on new production.
The Climate Change Act commits the UK government by law to reducing greenhouse gas emissions by at least 100% of 1990 levels (net zero) by 2050.

Bear in mind electricity consumption will increase when we're all forced into heat pumps and electric cars.
Plus all the CO2 from sectors that can't easily use electric.

The point is to use MORE electricity! That way you CAN use energy without the carbon emission rather than be forced into those emissions.
Sure there are industries that HAVE to emit CO2, if we are to have our comfortable lives. Almost all of them are "chemical" based.
Pass CO over hot ore and emit CO2. The oxygen being extracted leaving metallic copper or iron. Add a controlled amount of carbon back to the iron and you have steel.
Heat calcium carbonate (limestone) and pump hot air over it, emitting CO2. You get lime. Mix some other stuff in at the start and you get cement, used in concrete.
We can't avoid those type of industries, which is why we need to use as much wind, solar and nuclear to power our vehicles and heat our homes as we can.
Your argument is that we should ignore these facts, because we sometimes need to use gas?
Over the last year almost 60% of our electricity was provided by emitting carbon. Significantly less than five years ago! It will NEVER be zero, but we might emit less carbon in total if we use wind turbines for heating and transport at least some of the time. Instead of gas and oil all of the time.
Ps re gas boilers specifically. We need to increase very significantly the amount of electricity generated without carbon emission for simple resistive heating to make sense. Heat pumps, apparently a bete noire for some, change the numbers nearer to the status quo. Oh and nearly every UK home currently has at least one heat pump. It's called a refrigerator and is used to keep food cold.

Nuclear’s large volume and always-on nature has always been as much of a management challenge as a benefit. It is predictable, but has always run the risk of tipping the system into oversupply at times (such as overnight) when demand is low.
