Clean Growth: Technologies for meeting the UK’s emissions reduction targets Contents

3The Clean Growth Strategy

24.The Government published its ‘Clean Growth Strategy’ in October 2017, setting out how it intended to meet the fourth and fifth carbon budgets.64 This Chapter assesses the strategy as a whole, with specific sectors being discussed in subsequent chapters.

Policy gaps

25.Professor Jim Watson, Director of the UK Energy Research Centre, and Malcolm Brinded, representing the Royal Academy of Engineering and allied institutions, both praised the commitment expressed in the Clean Growth Strategy to meeting the UK’s emissions targets.65 Several stakeholders, such as the Renewable Energy Association, also pointed to what they perceived to be a lack of urgency in the strategy, or a mismatch between the ambition of the strategy and the Government’s current policies.66 When it published the Clean Growth Strategy, the Government estimated that the quantifiable policies proposed within it, if implemented, could lead to the UK achieving 94% and 93% of the emissions reductions needed to meet its fourth and fifth carbon budgets respectively (compared to baseline emissions in 1990).67 The Government’s most recent projections have updated this to 95% and 93% respectively.68 The Minister for Energy and Clean Growth, Claire Perry MP, told us, however, that she considered the projected shortfall to be “small”, and argued that since the projections were calculated she had seen “an acceleration of focus and policy delivery and a further reduction in cost”:

The Committee will have seen things like the spring statement and the announcement that we want all new homes from 2025 to be built without fossil fuel heating, which is an example of a policy for which we have costed no carbon reduction at all […] I am confident that we will meet these budgets within the timeframes we are given.69

Chris Skidmore MP, interim Clean Growth Minister, subsequently wrote to us to list the main policies whose emissions reductions potential had not yet been included in the Government’s projections:

26.The projected shortfall in emissions reductions was highlighted by Chris Stark, Chief Executive of the Committee on Climate Change, who warned us that there were “gaps in the policies that needed to be filled if we wanted to meet the fourth and fifth carbon budgets” and that there was additionally “lots of risk attached to those policies that the Government had already made”.71 Malcolm Brinded, representing the Royal Academy of Engineering, the Energy Institute and other engineering institutions, told us that there was widespread agreement that the UK was “not going to meet the carbon budgets on the trajectory [it is] on”.72 Although the UK has achieved the greatest decarbonisation of the G20 nations since 2000, its rate of decarbonisation has been slowing and it fell to fourth place among G20 nations for annual reductions in 2017.73 Lord Deben, Chairman of the Committee on Climate Change, told us that if he “were to put [his] finger on the thing that [he was] most worried about on climate change, it would be the lack of urgency”.74 The Minister for Energy and Clean Growth, Claire Perry MP, argued, however, that the UK had “the most detailed plan for emissions reduction” internationally and that although she “absolutely agree[d] that we need to raise our ambition”, “you have to have a really detailed plan to do that”.75

Deploying existing technologies

27.Numerous submissions to our inquiry highlighted the importance of supporting the deployment of existing technologies as well as the development of less mature technologies.76 For example, the Royal Academy of Engineering and allied institutions told us that “innovative policy making that works to break down silos and drives large-scale deployment of existing low-carbon solutions is more urgent than policy focused on the development of new technologies”.77 They argued that a “comprehensive review of incentives and regulations is required” to support this. Achieving the Government’s key targets would require an acceleration of deployment of low carbon technologies:

28.Although the rate of deployment may reasonably be expected to grow over the long timescales in question, there are also a number of areas in which Government policy to support the deployment of low-carbon technologies has been delayed or cut back. For example:

Developing less mature technologies

29.Although many of the technologies required for decarbonisation are ready for large-scale deployment, the Government and others have identified several important technologies that should be supported through research and development, large-scale demonstration and commercialisation.99 These include low-carbon heating technologies, carbon capture and storage, long-term energy storage technologies, small modular nuclear reactors and hydrogen as a fuel.

30.The Government’s Clean Growth Strategy highlighted £2.5bn of investment being put into low carbon technologies between 2015 and 2021.100 This funding aligns with the UK’s participation in ‘Mission Innovation’, a commitment made at the 2015 Paris conference on climate change to double spending on clean energy research and development from 2015 to 2020.101 The £2.5bn is broken down into:

31.The UK Energy Research Centre argued that “several analyses of public research and development spending on energy in the UK and in other countries have concluded that spending is much too low—particularly when compared to the scale of the challenge posed by climate change”.105 Professor Jim Watson, Director of the UK Energy Research Centre, conceded that it was “very difficult to assess” the ‘correct’ amount to spend on research and innovation for low-carbon technologies, and that the “international evidence […] is quite thin”.106 Nevertheless, he said that analyses tended to conclude that “budgets should be increased by about five times, sometimes ten times”.

32.Of the £2.5bn outlined in the Clean Growth Strategy, £1.14bn (44%) was for “basic and applied research”, £900m (35%) was for “technology development” and £530m (21%) was for “technology demonstration”.107 The Government explained that:

The Government is often more active at earlier stages of innovation, through investment in research, education and skills. Later on, private firms play a bigger role, bringing new technologies to market.108

Nevertheless, the Committee on Climate Change has warned that the Government’s innovation programme was “generally focused at early-stage innovation: research, development and some demonstration”, and that in order “to drive commercialisation and cost reduction successfully, it must be supported by funding and policies to drive deployment and learning-by-doing”.109 Many expressed similar opinions to us.110 The UK Energy Research Centre compared the time that it could take for new technologies to develop from early stage research through to commercialisation (typically three to four decades111) with the time left for meeting the fourth and fifth carbon budgets (five to fifteen years), concluding similarly that “policies to demonstrate, scale-up and commercialise existing technologies are perhaps more important [than fundamental research and development] if the UK is to successfully comply with carbon budgets in the 2020s and 2030s”.112 Damitha Adikaari, Acting Director of Science and Innovation for Climate and Energy at the Department for Business, Energy and Industrial Strategy, told us that “in the next iteration of this effort”, demonstration “is where the focus will be”.113

33.In particular, we heard that it would be important to have co-ordinated, large-scale trials rather than smaller, fragmented projects.114 Johnson Matthey, a multinational chemicals and sustainable technology company, told us that “scale is critical”, arguing that funding for projects greater than £100m in scale would be more effective than the same overall money spent on a larger number of projects of around £10m-scale.115 Malcolm Brinded, representing the Royal Academy of Engineering and allied institutions, explained that “you cannot do a big system design and understand what we mean by that without trying it”:

It is not something that you can do on a desk study and in theory; it is about how consumers respond and how all the integrated system reacts, particularly taking advantage of what big data, smart equipment and grids will enable consumers to do and how consumers will then respond, when it is coupled with clear price signals.116

Guy Newey, Director of Strategy and Performance at the Energy Systems Catapult, acknowledged that there were already “dozens” of demonstration projects in place but said that the “key challenge” was to “bring those together in big demonstrations testing the huge questions” such as low-carbon heating, nuclear power and carbon capture and storage.117 Both Mr Newey and Professor Watson highlighted that the Government would have to accept that some demonstration projects would also be unsuccessful.118

Co-ordinating development and deployment

34.Dr Jonathan Radcliffe, who leads the Energy Systems and Policy Analysis Group at the University of Birmingham and acted as the Specialist Adviser for our inquiry, told us that the deployment of new technologies “is a complex, non-linear process, with feed-backs and feed-forwards” and that it “requires support across the innovation process, with a combination of support for early stage research and development, demonstration activities and market mechanisms”.119 Guy Newey, Director of Strategy and Performance at the Energy Systems Catapult, made the similar point that if the Government “does not get the market structures right, there is a real risk that it will just be supporting isolated innovation projects”, and would not achieve the system-change required:

The lesson from the electricity system in the UK is that you need to get the innovation spend—the earlier-stage research and development stuff—lined up with the market mechanisms, and then you can see extraordinary cost reductions in technologies. If you do not do that, you will end up spending bits and bobs of money, but quite significant sums of public money, that will not lead to the kind of change you need.120

35.The most commonly referenced example in our written evidence of a technology whose development and deployment had been supported effectively was offshore wind power.121 The cost of offshore wind power has fallen from around £160/MWh in 2011 to around £60/MWh today,122 over which time the total generation capacity has increased from 1.8GW to 8.2GW.123 The most important aspects of the support that has enabled this development were frequently identified as:

The Committee on Climate Change has similarly said:

Offshore wind deployment exemplifies how clear goals, an ambitious strategy and well-designed mechanisms, can encourage and enable the market to reduce cost and help to build wider economic co-benefits. These lessons should be applied more broadly—to meet the challenges […] in transport, industry, buildings and agriculture.124

36.The Government’s own projections suggest that the UK is not currently on track to meet its existing emission targets, although we note that there are several significant policies and ambitions that have not yet been included in these calculations. Nevertheless, the rate of deployment of several key low-carbon technologies is significantly lower than what is required to meet the Government’s ambitions, and various stakeholders—including the Committee on Climate Change—have expressed concern at the current and projected rate of progress of the UK’s decarbonisation. In order to meet the fourth and fifth carbon budgets, emissions reductions cannot continue only in sectors that have decarbonised successfully so far, and must be significantly accelerated in sectors such as transport, heating and agriculture that have made little progress. The step-change in decarbonisation required will need policies to support the deployment and roll-out of existing technologies alongside, and co-ordinated with, significant research, development and demonstration of less mature technologies.

Technologies for export

37.In addition to the need for decarbonisation, the Clean Growth Strategy noted the “enormous potential economic opportunity” of clean growth with “an estimated $13.5 trillion of public and private investment in the global energy sector alone […] required between 2015 and 2030 if the signatories to the Paris Agreement are to meet their national targets”.125 However, despite highlighting this opportunity, the ambitions and policies in the Clean Growth Strategy focused heavily on deployment in the UK.

38.Professor Jonathan Gibbins, Director of the UK Carbon Capture and Storage Research Centre, argued that it was important to consider “how effective technology developments and investments in deployment in the UK are in influencing global outcomes”, saying that “technologies that convince other countries they can go to net zero are quite valuable”.126 Malcolm Brinded, representing the Royal Academy of Engineering and allied institutions, similarly told us that exporting low-carbon technologies to emerging economies offered “a huge opportunity to have much greater impact [on climate change], probably at lower cost, than just continuing to drive down our own targets”, but highlighted that these opportunities did “not get much focus” in the Clean Growth Strategy.127 Indeed, none of the fifty “key policies and proposals” in the Strategy addressed emissions reductions outside the UK.128 Mr Brinded acknowledged that “at a niche level the UK is quite good at this”, but argued that “we could do much more”:

There are some programmes from the Department for International Development and so forth and some companies in the UK whose whole focus is on, for example, mobile home solar systems in Africa and south Asia, which are now attracting tens or hundreds of millions in support. The UK is very well placed here […] but we could do much more to support an incubator system and infrastructure and the small- to medium-enterprises and innovators delivering these solutions on the ground. That requires more money on a more sustained basis, and an integrated strategy between the Department for Business, Energy and Industrial Strategy, the Department for International Development, the Department for Transport and the Department for International Trade.129

Professor Jim Watson, Director of the UK Energy Research Centre, indicated that he agreed “with a lot of that”,130 while Dr Nina Skorupska, Chief Executive of the Renewable Energy Association, said that, although different Government departments were “beginning to” improve support for export opportunities, “we still have to do a lot more”.131

39.The Government published an ‘International Research and Innovation Strategy’ in May 2019, which included elements addressing sustainability.132 However, this focused on international collaboration on research and innovation, rather than export opportunities for British technologies and companies.

40.The UK can simultaneously achieve economic growth and global emissions reductions through the export of low-carbon technologies to other countries. This potentially offers global emissions reduction at lower cost than the same level of reduction in the UK. However, opportunities for delivering emissions reductions outside of the UK were not included in the 50 key policies and proposals of the Government’s Clean Growth Strategy. When it laid legislation strengthening the UK’s long-term emissions reduction targets, the Government said that it would review the net-zero target within five years, to review the extent to which other countries had followed the UK’s lead in setting and acting upon decarbonisation targets.

41.Ahead of its review of international reaction to the UK’s net-zero target, the Government should actively encourage other countries to take similarly ambitious action. It should develop a strategy by the end of 2020, identifying opportunities for the UK to encourage and support decarbonisation in other countries, and prioritising action that will achieve the greatest global emissions reduction. This should include cross-Government action to support British companies exporting technologies that can deliver emission reductions abroad.

42.Tim Lord, Director of Clean Growth at the Department for Business, Energy and Industrial Strategy, told us that “there is a huge amount of cross-Government collaboration” on clean growth, including across the Treasury, the Ministry for Housing, Communities and Local Government and the Department for Transport.133 The Minister for Energy and Clean Growth, Claire Perry MP, added:

I think the fact that I do attend Cabinet, that we have a clean growth cross-Government strategy, and that for the first time ever we saw a green-focused financial statement, should give the Committee reassurance that it is absolutely percolating across Government.134

Nevertheless, the Minister is situated in one Government Department and is not a Cabinet Minister.135

43.The Government should increase the number of Ministers across Government Departments working on climate change, including a new Ministerial role at the Foreign and Commonwealth Office with explicit responsibility for delivering multi-lateral action internationally on climate change. Reflecting the critical importance of mitigating climate change, and to improve cross-Government co-ordination, the Minister charged with co-ordinating the UK’s action on national and international decarbonisation should be a full Cabinet Minister.
