The ability of suppliers to pay a buy-out price acts as a safety valve. It protects consumers of fuel from exceptional spikes in the price of renewable fuels. However, in normal market conditions, the continuing success of the RTFO scheme depends upon renewable fuel being supplied. Biofuels remain the main type of renewable fuel supplied under the RTFO. Recent increases in the cost of biofuels relative to petrol and diesel mean that there is a potential sustained commercial incentive for suppliers to buy out. Any reduction in biofuel supply will affect greenhouse gas emission savings from transport fuels, which poses the risk that there will be a gap in UK carbon budgets. It also risks damaging our biofuels industry and the future investments that are needed to keep us on the path to net zero.

The RTFO applies UK-wide and has been highly successful for the past 12 years. In 2019, renewable fuel supplied under the scheme saved almost 5.5 million tonnes of carbon dioxide emissions, which is the equivalent of taking 2.5 million combustion engine-powered cars off the road. Indeed, renewable fuel supplied under the RTFO currently contributes around a third of the savings required for the UK’s transport carbon budget. Clearly we need to ensure that the RTFO continues to provide effective market support.

We can all support the transition to renewable fuels across the transportation sector. As the Minister will be well aware, transport is the largest contributing sector to UK emissions, and progress in trying to decarbonise the sector has been very slow in recent years. To achieve that, we need to make the types of vehicle that we use, and the fuel they consume, more sustainable. It was disappointing to hear this week that the transport decarbonisation plan will not be published until spring 2021; we really do need an overarching strategy and coherence in policy making, as well as a greater sense of urgency.

The renewable transport fuel obligation was a key achievement of the last Labour Government. It has been a central part of encouraging the adoption of renewable fuels in transport, particularly fuels sustainably sourced from waste. I am pleased that the RTFO continues to be considered a success across the transport sector, but we must recognise that, as the climate emergency becomes more pressing and transport emissions continue to stagnate rather than reduce, it now needs reform.

The statutory instrument goes some way towards meeting the need for reform. As the Minister has explained, from 1 January, it will mean that the buy-back price multiplier will increase from 30p to 50p, strengthening the RTFO by providing more incentive for people to meet our renewable fuel requirements, rather than buying themselves out of their obligations. The Government estimate that, without acting to raise the buy-back price, we risk losing annual greenhouse gas savings of up to 6.5 million tonnes of CO 2 .

I hope to see more support from the Government for emerging sources of renewable fuels, especially in hard-to-decarbonise sectors such as aviation, shipping and HGVs, which at present cannot easily be electrified. Proper investment in genuinely sustainable fuels for those modes of transport may prove vital in meeting net zero targets and putting us back on track. I know that we are expecting more details of the sixth carbon budget soon, and I will be watching closely for future announcements.

I am delighted by the hon. Lady’s support for the statutory instrument, for which I thank her. She rightly referred to the transport decarbonisation plan that she and I have discussed on many occasions. It remains at the forefront of the Government’s efforts to decarbonise the entire sector. Regrettably, in the light of the covid pandemic, we have had to deal with very pressing public health issues, but that has not detracted from our intense work on the plan, which we will publish in spring next year.

Following my conversations with people in the sector, I am concerned that some companies, particularly those operating fleet vehicles or bus companies —I know that the right hon. Member for Scarborough and Whitby has a company in his constituency that is keen to manufacture cleaner buses—have been so financially hit by covid that they have put their plans on hold, because it is not an ideal time for a company to upgrade its vehicles if it has not made a profit in the previous year. Will that affect what is in the decarbonisation plan?

I do not want to stray too far from the statutory instrument, but the hon. Lady rightly raises very important questions. I will be happy to discuss that further with her, but I want to reassure her that our commitment remains. We work very closely with the sector, as she does, and we understand those natural concerns. Of course, the Government have supported the entire economy to the tune of at least £330 billion, which has gone to transport operators and many others. We recognise the challenges that operators face, but we nevertheless remain determined to decarbonise the transport sector.

The order makes a small but important amendment to ensure that the RTFO continues to support the renewable fuels industry as intended. We need the industry to drive down emissions in sectors that are harder to decarbonise, such as heavy goods vehicles and aviation, and to deliver the cleaner fuels that will play an even greater role in achieving our aim of a greener and more prosperous economy. I reassure members of the Committee that we have the most ambitious crop cap in Europe for fuel sources, which is 4% and will be decreasing to 2%. We have therefore taken note of the concerns that hon. Members have raised.

It is true that as we transition to zero emissions vehicles, we cannot ignore measures to reduce emissions from the conventional road vehicles in use today, particularly given the contribution of renewable fuels to meeting UK carbon budgets. We will be setting out in our transport decarbonisation plan more detail about the future of low-carbon fuels across transport modes, and that will be published in spring 2021.
