It is a key sector and a global R&D focus point with £3.75bn invested in 2019, yet government ambitions for phasing out the sale of internal combustion engine vehicles at some point in the 2030s mean the next few months will be critical in determining its future. The Government has pledged that by 2050 the UK will be a ‘net zero’ emitter of CO2. Emissions have reduced since 1990 and the UK has done well so far in meeting its CO2 reduction targets. However, at present, the UK is set to fall behind by 2023. Now that coal-fired power stations have closed down and we have started to use much more natural gas and renewable energy, road transport is one of the biggest CO2 emitters. We need to reduce this, and quickly. While a clear and achievable target for ending the sale of petrol and diesel cars is vital for the industry to prepare for a managed transition to a cleaner future, we should not be fooled into thinking this alone will solve the problem. We need to address the decarbonisation of both vehicle and fuel to have any real hope of meeting our CO2 reduction ambitions. With a new generation of clean automotive vehicles and technologies on the horizon, government and industry should work together to identify what position we as a nation want to play and ensure that our domestic market is ready and able to meet that desire. The UK is home to some incredibly innovative companies and research institutions. We should foster their creativity by taking a technology neutral approach to our ambition for emission reduction, allowing the industry to do what it does best; innovate. For example, we have some amazing electric cars already on the market, but hydrogen is better placed for larger vehicles and so Government policy should encourage these technologies to be explored too. This report is aimed at informing the debate on emissions reduction so that policy makers can make the right decisions and to ensure the UK is able to maintain a strong domestic automotive market, providing a solid foundation for global exports. Matt Western MP Chair All Party Parliamentary Motor Group Page 3 of 21 DECARBONISING ROAD TRANSPORT INTRODUCTION Reaching net zero carbon by 2050 will be a huge challenge for society and industry in the UK. In their latest annual progress report the Committee on Climate Change (CCC) made a series of recommendations on how to decarbonise road transport, advocating for a greater penetration of Ultra-Low Emission Vehicles (ULEVs) into the market and the establishment of infrastructure to support these new vehicles. The UK automotive industry is fully committed to the decarbonisation of its products whilst also minimising the environmental impact of its operations. Through investments in new technologies, emissions from vehicles has fallen steadily since 2000, when new CO2 based taxation was brought in. This improvement has however stalled in recent years due in part to government policy on diesel, a lack of Ultra Low Emission Vehicles (ULEV) on the market, the cost of these vehicles and the concerns around charging availability. This trend seems to have reversed in 2020 with Q1 data from the Department for Transport detailing new car CO2 emissions falling to their lowest ever levels of 118.3g/km2. Coupled with this the number of battery electric and plug in vehicles increasing from 3.15%1 in 2019 according to the Society of Motor Manufacturers & Traders (SMMT) to 8.8%2 YTD in 2020. However, tailpipe emissions are not the whole story. We need to consider the whole picture of emissions in understanding the impact different technologies have on the environment. To have a real impact on our emissions from road transport we need to address the decarbonisation of both vehicle and fuel to have any real hope of meeting our climate reduction ambitions. This is sometimes referred to as ‘Well to Wheel’. Accepting a range of technologies will play a role in meeting our road transport decarbonisation ambitions; the industry will be able to decarbonise in a shorter time frame than mandating one particular technology, which may not be suitable for all applications. This approach, often called a Technology Neutral Approach, will allow our highly innovative industry to be a leader in the development of some of these new technologies such as Battery Systems, Motors & Power Electronics, Lightweight Structures, Hydrogen and Synthetic/E-Fuels. All of which have a role in reducing the carbon emissions from road transport. The current number of vehicles registered on UK roads stands at over 40 million1, covering a range of different vehicle types. This report aims to illustrate the differences between the various vehicle segments, the technologies available and their role in supporting road transport decarbonisation. ‘ WE NEED TO DECARBONISE BOTH VEHICLE AND FUEL TO HAVE ANY CHANCE OF REACHING OUR CO2 EMISSION REDUCTION AMBITIONS.’ MATT WESTERN MP CHAIR, ALL PARTY PARLIAMENTARY MOTOR GROUP NO.

Each of these segments has its own attributes (size, power, weight, range & cost) and therefore may require different technologies to meet carbon neutrality targets. As an example, the driver of a Ford Fiesta will have chosen that vehicle based on their needs and vehicle use, whereas the driver of a Ford Transit van has different needs, so has chosen that vehicle based on those needs. One is optimised for the school run, the other for package delivery. These two vehicles are very different and therefore have different needs when it comes to their respective powertrains. This segmentation analysis is explored further below. Passenger Car There are 35 million passenger cars on the road in the UK according to the SMMT1. These vehicles cover a range of segments with differing types of vehicle for different applications, these segments are classified by Euro NCAP3 and are explained in Figure 1 below.
