UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.



The CAA Environmental Sustainability Panel is a specialist, non-statutory body providing expert technical advice to the CAA. The Panel supports and challenges us on the delivery of our environmental sustainability strategy as we develop our policy and position across our regulatory and advisory functions. These functions relate to the safety and security of the aviation sector and protection of consumers who use it, and include supporting and challenging the aviation and aerospace sectors as they manage and reduce their negative environmental impacts, such as emissions and noise, and advising Government.  

The Environmental Sustainability Panel will act as a 'critical friend' to the CAA, in a similar way as our existing Consumer Panel, providing expert technical advice to ensure that environmental and sustainability issues are considered in our policy development to the extent that current legislation requires and allows.

The key activities of the Panel are to:

  • provide expert technical advice to the CAA to support our work programme relating to our environmental roles, or on specific tasks that we may require, including input to our response to any relevant external consultations;
  • help the CAA to understand and take account of environmental interests and impacts in our regulatory policy and framework (although the Panel will not be expected to review or comment on individual regulatory decisions);
  • challenge and support the CAA on our progress towards our strategic focus on improving environmental performance, both within the aviation and aerospace sectors and within the CAA itself, including informing the delivery and future evolution of our environmental sustainability strategy;
  • Provide advice and critique on the CAA’s research and help identify where further research may be needed to inform our sustainability agenda.

The Panel is not set up to:

  • campaign publicly or deal with individual complaints from the public;
  • represent or correspond directly with air travellers, industry or community groups unless requested to do so by the CAA;
  • be involved in or comment on operational issues or complaints raised by individuals, such as noise from flight paths.

The Panel will work in accordance with its Terms of Reference.

Environmental Sustainability Panel Members

The Environmental Sustainability Panel brings a wealth of environmental expertise in aviation and other sectors across noise, carbon and other environmental impacts, covering both the technical challenges and solutions for greening aviation, and the impact of emissions and noise on public health.  The Panel members, each of whom will contribute around one day a month to the role, are:

Dr Ruth Mallors-Ray, Chair
Ruth has a broad and extensive understanding of both the aviation industry and the complex relationships between government, industry, academia and the public.  An Associate Director of Connected Places Catapult and Chair of the Strategic Advisory Board of the Digital Supply Chain Innovation Hub, and the former Chief Operating Officer of the Aerospace Technology Institute, Ruth has significant experience of strategy development and execution with a focus on challenge led innovation with impact. She is an experienced chair of technical and advisory panels, focusing on engagement and consensus building on complex topics, with a strategic approach to act in the best interests of the whole and achieve the outcomes for a range of stakeholders.

Professor Charlotte Clark
Charlotte is a Professor in Environmental Epidemiology at St George’s, University of London. She is an expert in applying social science to the issue of noise effects on health and communities, and has broad experience working with airports, regulators, governments and communities. Charlotte will bring objective and evidence-based advice on the impacts of noise on the community to the Panel.

Dr Martin Hawley
Martin is an expert in Air Traffic Management and airports, especially around the interfaces of business, technology and operations. His experience and skills include climate technology, environmental economics, sustainability innovation and performance indicators. He brings wide international experience and a strong grounding in research methodology.

Professor David Lee
David is a Professor of Atmospheric Science and Director of the Centre for Aviation, Transport, and the Environment (CATE) at Manchester Metropolitan University. With 25 years of experience as a specialist in climate science, having participated in many assessments of the Intergovernmental Panel on Climate Change, he is skilled in developing the links between science and policy. He has particular interest in the policy aspects of mitigating the impacts of aviation on climate.

Professor Alastair Lewis
A Professor of atmospheric chemistry at the University of York, Alastair has over 25 years of experience in scientific research on the environmental impacts of transport, fuels and combustion on public health, climate change and the response of ecosystems. He is also the Science Director for the National Centre for Atmospheric Science, and is passionate about communicating science, technology and risk to the general public.

Dr Chikage Miyoshi
Chika is a Reader in Environmental Systems for Aerospace at Cranfield University Academic. She is involved in developing multidisciplinary research projects with a focus on the environmental and economic elements of aviation, and brings expertise in the impact of economic instruments on aviation, including the EU Emissions Trading Scheme and carbon and fuel taxes.

Professor Anil Namdeo
Anil is a Professor of Air Quality Management at Northumbria University. His research focuses on environmental and sustainability assessment of land use, transportation and other developmental policies. Passionate about translating scientific information in easy-to-understand language, his overall focus is on developing win-win policies by providing scientific expertise to support analysis and trade-offs between carbon, noise and air quality.

Professor Mark Westwood
Mark is a Professor and Head of Centre for Aeronautics at Cranfield University. A technology leader and specialist in aerospace and autonomous systems, including R&D in drone and advanced air mobility sectors, he is passionate about exploring the opportunities presented by new technologies and developing them into sustainable, practical real-world applications.
