The UK has committed to huge CO2 cuts as it gears up to host the UN COP26 climate summit in November.

Boris Johnson pledged a 78% fall by 2035 compared to 1990 levels.

The Prime Minister had previously targeted a 68% reduction by 2030.

For the first time, climate law will be extended to cover international aviation and shipping as the UK bids to hit net-zero emissions by 2050.

It comes ahead of a US summit on Thursday, where President Joe Biden is due to outline his targets.

It is understood both countries, will press China and other nations, to make stronger commitments too.

The UK accounts for 1.1% of global emissions, compared with 15% in the US and 26% from China.

A 78% UK cut will require slashing demand for carbon-intensive activities, the independent Climate Change Committee said.

And activists are sceptical reality will match Government rhetoric.

Leo Murray, of climate charity Possible called the pledge “fantastic”, but added: “We’re not on track to meet previous commitments and in many ways the Government is still failing.”

How we heat our homes, commute and even eat could be set to alter forever.

The main changes include

How we heat our houses will switch

Homes will not be heated by natural gas or oil boilers in the coming decades , with the majority switching to heat pumps, which are powered by electricity.

But... green home renovations run into thousands of pounds, yet the Government has just scrapped the only initiative to help fund the up-front costs.

Cutting building emissions

Reducing emissions from buildings, which account for 17% of UK climate pollution, is a priority. No1 priority is to cut the amount of caused by heating.

But... requires millions of rented, owned and council homes to be made more energy efficient, with measures including better wall insulation and installing double or triple glazing.

No more gas-guzzlers

Electric cars are the future

The sale of new petrol and diesel cars, motorbikes and vans, including plug-in hybrids, will have to be phased out by the early 2030s, and even HGVs will start to shift to greener alternatives.

But... the rollout of charging points has been woefully slow and will require 400,000 public chargers by 2030, up from 35,000 currently.

Reduction in flights

Growth in demand for flights will have to end and flying may become more expensive to help reduce demand, particularly for frequent flyers who may face a new levy.

But... this could also impact families flying for holidays, especially with limited train options to Europe.

Less meat and dairy

The meat industry contributes heavily to global warmimg

We will be encouraged to waste less food and eat far less animal product. The CCC recommends a 20% shift away from meat and dairy by 2030.

But... it is very vague on how this will be encouraged, whether prices will increase or help given to farmers if demand drops.
