Chapter 7 Research and Systematic Observation 371 The Department for Transport (DfT) (and the Office for Zero Emission Vehicles) is also heavily involved in low-carbon policy in the UK, given the significant contribution that transport emissions make to total UK emissions and the challenges in decarbonising this sector. The UK's ambition is for a modern, low-carbon, low-pollution transport system with net zero emissions in 2050-as set out in the Transport Decarbonisation Plan, published in July 2021. In support of this, a range of programmes are being undertaken, including the £1 billion Automotive Transformation Fund supporting development of an electrified automotive supply chain, and funding for innovative technologies including £180 million for sustainable aviation fuels, £125 million of UK Government funding for the Future Flight Challenge, and £23 million for the Clean Maritime Demonstration Competition. Building on the success of our £20 million zero emission road freight trials, these are being expanded to trial three zero emission HGV technologies at scale on UK roads. Since 2020, the UK has committed over £2.5 billion to the electric vehicle transition, of which over £1.6 billion is to support charging infrastructure. Foreign, Commonwealth and Development Office (FCDO) has an active interest in the funding of climate science, reflecting its commitment to tackling climate change and its effects as a driver of future instability and poverty. Further details on FCDO funding of research, which spans both mitigation and adaptation, can be found in the international cooperation section below.
