Britain will spend more than US$1 billion to promote electric and other low-emission vehicles, and step up spending on research and innovation, as part of plans to invest US$3.3bn by 2021 to help meet its climate change targets.

The minority Conservative government’s Clean Growth Strategy, which details government spending between 2015 and 2021, includes heavy investment in science, research and innovation to help reduce carbon dioxide emissions.

Reuters Newsagency reports around US$1.2bn will be spent on innovation.

This includes US$351 million for smart energy, US$610m to support new nuclear technology and US$235m to help develop new technology to further reduce the cost of renewable energy, including innovations in turbine blades for wind power.

The funding will cover programs in the energy, transport, agriculture and waste sectors.

The government said it said it would spend US$1.2bn “supporting the take-up of ultra low-emission vehicles, including helping consumers to overcome the upfront cost of an electric car,” but gave no details of how the scheme would work.

In July, the government said it would ban the sale of new petrol and diesel cars and vans from 2040.

Britain has a legally binding target to cut greenhouse gas (GHG) emissions, blamed for global warming, by 80 per cent by 2050 compared with 1990.

Reuters reports government data showed by the end of 2016 Britain was more than half way to meeting the target, having cut GHG emissions by 42 per cent compared with 1990 levels.

However, with many of the cheaper and easier emission reductions completed, the government said it would “not be easy” to meet its targets.

Britain said it was committed to using a price on carbon dioxide as a means of reducing emissions but said it is yet to determine whether it will remain in Europe’s Emissions Trading System (ETS) when it leave the European Union.

The plan showed the government is keeping faith with attempts to develop technology to collect emissions from power plants and industry and store them underground despite high-profile setbacks.

The government will invest up to US$133m in technology to capture, use and store carbon dioxide emissions and in industrial innovations to drive down emissions, according to the plan published on Thursday.

The British government had viewed carbon capture and storage (CCS) as vital to help it to meet emissions targets, but two competitions over the past 10 years have failed to produce a commercial-scale project.

A parliamentary watchdog said in January that Britain had spent US$223m on two failed initiatives to help to fund CCS technology.

The government confirmed a plan, first announced in 2015, to phase out coal-fired power stations by 2025 unless they are fitted with CCS technology.

As a part of efforts to replace Britain’s ageing coal power stations, the government pledged US$739m for clean electricity subsidy auctions for renewable power.

The government hopes clean energy projects will be an important driver of growth, adding to the 430,000 jobs it said already existed in British low-carbon businesses. It believes the low carbon economy could grow by 11 percent a year up to 2030.

Business lobby group the CBI welcomed the plan and said it provides clarity for the investment community.

“There remains significant heavy lifting in other parts of the economy, such as heat, transport and improving the efficiency of our homes and industry, and concerted efforts will be needed to ensure we can meet our ambitions,” Neil Carberry, the CBI’s managing director for people and infrastructure, said.
