My hon. Friend is absolutely right: there can be no clean maritime without clean ports. He is absolutely right to raise the opportunities that exist for our ports, and I thank him for his tireless, passionate advocacy for Lowestoft. I can confirm that my Department, DEFRA and BEIS meet regularly to ensure that our work is aligned and, in particular, that our work on renewable energy and maritime decarbonisation is complementary in approach, because providing the former is a big part of providing the latter.
