Baroness Worthington is a British environmental campaigner and life peer in the House of Lords. She has promoted change in attitudes to the environment, and action to tackle climate change, and founded Sandbag, a non-profit campaign group designed to increase public awareness of emissions trading, in 2008. Bryony was born and grew up in Wales and graduated in English literature at Queens' College, Cambridge, before joining Operation Raleigh as a fundraiser. In the mid 1990s, she worked for an environmental charity, and by 2000 had moved to work for Friends of the Earth as a climate change campaigner. She then worked for the Department for Environment, Food and Rural Affairs, implementing public awareness campaigns and helping draft the Climate Change Bill, before becoming head of government relations for the energy company, Scottish and Southern Energy. She left to form Sandbag in 2008.
She was created a life peer on 31 January 2011 with the title Baroness Worthington, of Cambridge in the County of Cambridgeshire, and sat on the Labour benches, until redesignating as a non-affiliated member in April 2017.
Lady Worthington was the lead author in the team which drafted the UK's 2008 Climate Change Act. This landmark piece of legislation requires the UK to reduce its carbon emissions to a level 80% lower than its emissions in 1990. At the time Worthington was working with Friends of the Earth working on their Big Ask campaign, but was seconded to government to help design the legislation.
