Claire O’Neill entered politics in 2007 after a transatlantic career in consulting and finance, initially as a policy advisor to George Osborne, the then Shadow Chancellor and then as the Conservative MP for the Devizes Constituency from 2010 - 2019.
She served in several Ministerial positions before becoming Climate Change Minister and then attending the UK Cabinet as Minister for Energy and Clean Growth. Claire wrote and implemented the UK’s Clean Growth Strategy; formed the Green Finance Taskforce; launched the global Powering Past Coal Alliance to end coal-powered electricity generation and negotiated the UK’s Offshore Wind Sector Deal that dramatically dropped the cost of this vital renewable energy source. In 2019 she brought forward the ground-breaking legislation that committed the UK to be a Net Zero emissions economy by 2050 and she also formulated the UK’s successful bid to host the United Nations 2020 Climate Change Conference known as COP26.
