She has been described as a "widely respected expert on global climate and energy policy",^[2][3][4] serving as a board member for numerous not-for-profit organisations. In 2012 she was referred to as an "eco-warrior" by The Daily Telegraph.^[5]

Diana Fox Carney is the daughter of Christopher Fox and Jennifer Atkinson who managed an estate when she was born.^[6] She spent her earliest years in the Quarwood House, a Gothic mansion near Stow-on-the-Wold, that was later purchased by John Entwistle of The Who.^[6] The family then purchased a lucrative pig farm,^[7] while Diana and her sister attended Oxford High School for Girls.^[6] She then attended Marlborough College in Wiltshire.^[8] Her sister Tania would go on to marry Robin Cayzer, 3rd Baron Rotherwick.^[1]

She has a degree in Philosophy, Politics and Economics and a master's degree in agricultural economics from the University of Oxford and an MA in international relations from the University of Pennsylvania.^[9] In the 1990s, she was one of the stronger skaters on the women's team of the Oxford University Ice Hockey Club, where she met her future husband Mark Carney, who played goaltender for the men's team.^[10]

Fox Carney has held senior roles at think tanks in Canada and the UK, focused primarily on energy and climate. She has worked as an agricultural researcher in Africa, for the charity IPPR, and served as the executive director of Pi Capital in the UK.^[11][12] Fox Carney has served on the boards of Save the Children, Friends of the Royal Academy, Ashden, ClientEarth, the Shell Foundation, and BeyondNetZero.^[1]

In 2013, Carney spoke to a Canadian Parliament’s finance committee about the increasing gap between the rich and poor globally, noting that two-thirds of people were living in countries where the gap had grown over the previous decade.^[13]

In April 2013, Carney, who was vice president of research at the Canada 2020 think tank at the time, contributed a paper to one of its conferences supporting carbon pricing dialogue. Later that month, she made an appearance on CBC News Network's Power & Politics to discuss the issue and addressed stories in the British media by stressing that she was her own person with her own ideals separate from her husband.^[14][15] After leaving Canada 2020, she became the London-based Institute for Public Policy Research's director of strategy and engagement, a position she left by 2025.^[16]

Fox Carney has been a senior advisor alongside Gerald Butts at Eurasia Group since May 2021.^[17] In October 2021, Fox Carney was appointed as a strategic adviser by Willis Towers Watson in its award-winning Climate Resilience Hub.^[18][19]

Carney met her husband, Mark,^[1] while at the University of Oxford.^[20] The couple married in 1994,^[16] while Mark was finishing his doctoral thesis.^[21] They have four children and lived in Toronto before moving to the Rockcliffe Park neighbourhood of Ottawa and then moving to London in 2013.^[22] One of their daughters, Cleo Carney, introduced her father at the Liberal Party convention in 2025. They moved back to Ottawa when Carney left his role at the Bank of England in 2020.^[23]

In 2012, Carney caught the attention of the British press with The Daily Telegraph labelling her as an "eco-warrior" for expressed sympathy with the anti-banking occupy movement stating "global financial institutions are rotten or inadequate".^[5] In 2013, she received criticism after publicly stating her husband's $7,700/week housing allowance was insufficient.^[7][24]
