Climate change: UK government to commit to 2050 target

Greenhouse gas emissions in the UK will be cut to almost zero by 2050, under the terms of a new government plan to tackle climate change.

Prime Minister Theresa May said reducing pollution would also benefit public health and cut NHS costs.

Britain is the first major nation to propose this target – and it has been widely praised by green groups.

But some say the phase-out is too late to protect the climate, and others fear that the task is impossible.

The UK already has a 2050 target – to reduce emissions by 80%. That was agreed by MPs under the Climate Change Act in 2008, but will now be amended to the new, much tougher, goal.

The actual terminology used by the government is “net zero” greenhouse gases by 2050.

That means emissions from homes, transport, farming and industry will have to be avoided completely or – in the most difficult examples – offset by planting trees or sucking CO2 out of the atmosphere.

The government’s advisory Committee on Climate Change recommended the “net zero” target in May.

Its report said if other countries followed the UK, there was a 50-50 chance of staying below the recommended 1.5C temperature rise by 2100.

A 1.5C rise is considered the threshold for dangerous climate change.

Laurence Tubiana, an architect of the crucial Paris climate agreement, told the BBC: “This is a historic commitment that will reverberate right around the world.

“All eyes will now turn on the rest of the EU to match this pledge.”

Theresa May said the UK led the world to wealth through fossil fuels in the industrial revolution, so it was appropriate for Britain to lead in the opposite direction.

“We have made huge progress in growing our economy and the jobs market while slashing emissions,” she said.

“Now is the time to go further and faster to safeguard the environment for our children. We must lead the world to a cleaner, greener form of growth.”

Number 10 said it was “imperative” other countries followed suit, so there would be a review within five years to ensure other nations were taking similarly ambitious action and British industries were not facing unfair competition.

Scotland has already committed to reducing greenhouse gas emissions to net-zero by 2045, five years ahead of the UK government’s target.

The Committee on Climate Change (CCC) recommended Wales should aim to cut emissions by a lower target of 95% by 2050 due to the importance of the farming industry to rural communities. But the Welsh government has since said it wants to go further – and will commit to net-zero by 2050, like the rest of the UK.

Northern Ireland is the only devolved administration which does not have its own climate change legislation and emissions targets.

How will it affect people?

If ministers decided to clamp down on meat-eating or on flying, that would meet serious opposition.

But the government will attempt to make the clean revolution as painless as possible. Technology improvements like LED light bulbs, for instance, save emissions without people noticing.

The same is true if people get hydrogen central heating instead of gas, or if they are obliged to drive electric cars rather than petrol vehicles.

But there will need to be a massive investment in clean energy generation – and that has to be funded by someone.

The government hasn’t yet spelled out if the cost will fall on bill-payers, or tax-payers, or the fossil fuel firms that have caused climate change.

And then there’s the international dimension. Prof Dieter Helm, from the Blavatnik School of Government at Oxford University, said: “From the UK’s end, doing this unilaterally, we have to be very careful that we don’t simply say: ‘we’re going to reduce the emissions from our cars and our power stations here in Britain, but we’re going to carry on importing those emissions from overseas.’

“We don’t make very much in this country. Manufacturing is only 20% of the economy. Most of the stuff that you go and buy in the supermarket… it’s all imported.”
