Following weeks of civil defiance protests by the climate group Extinction Rebellion with the aim of raising awareness and pressuring the government into finding lasting solutions to the current global climate crisis, Britain’s parliament declared a symbolic climate change “emergency” in a nod to the increasingly vocal activist movement.

According to the Government Climate advisers, Britain should commit to a net zero greenhouse gas emissions target by 2050, a goal that could require phasing out new petrol and diesel cars by at least 2035 and a 20 percent cut in beef and lamb consumption. Their recommendations emanated in a report released on Thursday, May 2nd 2019.

Britain currently seeks to reduce greenhouse gas emissions (GHGs) by 80 percent compared with 1990 levels by 2050. However, campaigners insist that move’s effort will be too little to meet pledges made under the 2015 Paris climate agreement to try to limit a rise in global warming to 1.5 degrees Celsius.

“The UK can end its contribution to global warming within 30 years by setting an ambitious new target to reduce its greenhouse gas emissions to zero by 2050 (on 1990 levels),” the Committee on Climate Change (CCC) report stated.

The government-commissioned report said the new target is achievable with existing technology but can only be met if the government ramps up climate policies.  A current goal to phase out new petrol and diesel cars by 2040 would come too late and would need to be brought forward to at least 2035 or 2030 if possible.

Several European Union countries or cities have proposed banning diesel cars in a clampdown on polluting emissions, such as Spain, also from 2040.

In addition, from the report, the increased renewable and low-carbon electricity would be required to meet the UK’s target, and technology to capture and store or use carbon dioxide emissions from industrial sectors must be adopted. Households will be educated and be weaned off natural gas heating and switch to low-carbon alternatives such as hydrogen or heat pumps, the report said.

Besides the renewable energy, Britons should be encouraged to consume around 20 percent less beef, lamb and dairy products, while growth in air travel would likely need to be curbed unless the aviation sector adopts low-carbon fuels such as biofuel or electrified air travel.

A statement from Conservative Prime Minister Theresa May’s government said: “We are not immediately accepting the recommendations set out in the (committee’s) detailed report but will be responding in due course to ensure the UK continues to be a world leader in tackling climate change.”

Climate scientists have warned that failure to limit global temperatures at 1.5 degrees would lead to rising sea levels, catastrophic weather events such as droughts and floods and the loss of species.

The CCC report said the cost of meeting the new target would be around 1-2 percent of Britain’s GDP – tens of billions of pounds a year. It said the Treasury should undertake a review of how the transition should be funded. The cost of delay, or inaction, would be much higher, the report said.

Sam Fankhauser, director of the Grantham Research Institute on Climate Change at the London School of Economics and Political Science, said Britain was not now even on track to meet its carbon budget goals for the late 2020s and early 2030s.

The world’s fifth largest economy should start implementing the new measures sooner so that it does not become strenuous for the taxpayers hence legislation would have to go to parliament before a new climate target could become law.

CCC Chief Executive Chris Stark confirmed to journalists the law could be in place before international climate talks in Chile at the end of the year since there was cross-party consensus in Britain on the need to act.

According to Stark, if Britain sets a net zero target, it could encourage other countries to do the same and increase the likelihood of the Paris climate target being met. China is currently the world’s climate leader due to its ballooning green energy sector and has made large strides in managing air pollution.
