Ashden team

  • Harriet Lamb


    I joined Ashden as CEO in May 2019, taking responsibility for developing and implementing the organisation’s ambitious new strategy to tackle climate change.

    I have been CEO at peacebuilding organisation International Alert and spent 15 years leading Fairtrade in the UK and globally. I have always worked for NGOs with a focus on international development, peace and the environment. I worked in the UK on refugee and low pay issues, and lived in India for six years. My book Fighting the Banana Wars and Other Fairtrade Battles was published in 2008, and I was appointed CBE in 2006. I am a cycling obsessive who loves gardening and walking my dog.

  • Joanna Walton

    Director of Communications and People

    I have been at Ashden since 2005 and oversee the promotion of Ashden and Ashden winners to a wide audience. I am a member of the Executive Management team with particular responsibility for HR. In my time at Ashden I have overseen the smooth delivery of 12 Ashden Awards ceremonies with speakers including former US Vice President Al Gore, Sir David Attenborough and Ashden’s Patron HRH The Prince of Wales.

  • Edward Dean

    Director of Development

    I lead on securing the income that Ashden needs to fund each of our Awards and to develop our UK and International programme work. Success for me is much more than what the balance sheet looks like; it’s about building relationship with individuals and organisations that share our mission to bring sustainable energy to all.

  • Giles Bristow

    Director of Programmes

    Before Ashden, I was first the Head of Energy, then Director of Programmes at Forum for the Future with responsibility for our work in the energy and food systems. I found my way to Forum via an earlier career as an environmental law specialist. My first degree was a BSc in Geography and I have written a thesis on the impact of UK fiscal policies on the project financing of onshore renewables during a Masters degree in Energy Policy and Sustainability. When not thinking about energy, innovation and system change, I can be found walking my retired greyhound (Bonnie) or surfing or kitesurfing somewhere on the UK coast.

  • Lucy Blackburn

    Senior Corporate Partnerships Officer

    I am responsible for the stewardship of Ashden’s corporate partners and fostering new relationships, both in the UK and internationally. At its heart this means the development of partnerships that are mutually beneficial and based on a shared commitment to sustainability.

  • Jennifer Lauture

    Development Officer

    I assist the development team in securing funding to run and develop our Ashden Awards and programme work. This involves research into funding prospects, writing persuasive proposals, reporting to current funders, maintaining stewardship and developing relationships with individuals interested in sustainability and taking action against climate change.  

  • Emma-Louise Frost

    Communications Manager

    As part of the communications team, I’m involved with everything from writing blog posts, looking after our social media channels and managing the website, to helping promote our events and fantastic winners. I was new to the sustainable energy sector before Ashden, and I learn something new from the team every day.

  • Craig Burnett


    I make sure Ashden's voice is powerful and passionate. As well as thinking about the climate stories we want to tell, I write and edit articles, pieces, reports, video scripts and more.

  • Aditi Gaddam

    Junior Programme Officer (Sustainable Energy for International Development)

    I support the Programme Team by conducting research for our awards process and other programmatic work to progress our strategy. I also support various aspects of the international awards week and business support programmes. I am an Economist by training and have a Masters in Energy and Climate Policy and excited to be part of the sustainable energy for development community. In my free time you’ll find me experimenting with my camera or time-travelling (through books).

  • Alex Green

    Programme Manager (Awards and Schools)

    I lead our schools programme, LESS CO2, which supports schools to become zero carbon. We work directly with schools through our peer-to-peer mentoring scheme, as well as engaging with government and sector stakeholders to campaign for change. I also project manage the Ashden Awards – overseeing and bringing together our awards call for entries, judging and assessment processes.

  • Mike Pepler

    Awards Manager (Liveable Cities)

    I manage the Liveable Cities awards process, from researching themes for the awards and designing application forms to planning the judging process and visiting the applicants. With my background in engineering, research and computing, I also get involved in technical aspects of almost all the team’s work at some point in the year.

  • Simon Brammer

    Head of Cities

    I head up our cities programme that aims to create liveable, sustainable cities. At the heart of our approach is a network that brings together the UK metro mayor regions. Using our winners to demonstrate the possibilities, we are showing policymakers that by tackling climate change you can simultaneously address a multitude of other challenges. Challenges such as cleaning up toxic air, providing affordable warm homes or creating new, fairly paid jobs. We want a just transition. 

  • Cara Jenkinson

    I work with Simon Brammer to support our UK Award winners, helping them to share best practice and showcase their work to influential audiences including policymakers.
