Executive team

Charlotte Morton, Chief Executive 


A practising lawyer for 10 years, Charlotte Morton studied for her MBA at London Business School before setting up a car club business. Asked to establish the business side of ADBA in 2009, she saw the potential of an industry that can deliver huge value to the UK. But she didn’t stop there. In 2016, she played a pivotal role in establishing the World Biogas Association to promote and increase the rate of uptake of biogas globally – she sees biogas as having an even bigger potential on a global scale, especially as the world takes on achieving the Paris Agreement climate change targets and UN Sustainable Development Goals.

Charlotte is also on the board of Green Gas Trading Ltd, which runs the Biomethane Certification Scheme.
