Carla Suzanne Denyer (born 24 September 1985)[2][3] is a British politician who has served as co-leader of the Green Party of England and Wales alongside Adrian Ramsay since 2021 and as the Member of Parliament for Bristol Central since 2024.

She is also noted for her lead role in bringing about Bristol City Council's declaration of a climate emergency in 2018, which was the first in Europe.

[19] From 2012 she developed an interest in ethical investment and specifically fossil-fuel divestment through participation in the Quakers and the UK Fossil Free campaign.

[30][31] In June 2021, Denyer was appointed as the Green Party's housing and communities spokesperson,[32] and in July 2021, she took on the role of shadowing Bristol's Labour cabinet on climate and ecology, holding the position jointly with Lily Fitzgibbon.

[46] Denyer also campaigned extensively on transport; work included trying to introduce congestion charging to Bristol[47][48] and seeking 'a major upgrade of Bristol's transport, with safe connected cycling routes, a joined up and efficient bus network and a levy on corporate parking to raise funds for more improvements'.

[52] Her other campaigning has included improving conditions for people renting their homes,[53][54] and opposing council tax increases for poorer taxpayers[55][56] while seeking what Denyer has described as "more ambition from the mayor's office in tackling austerity" by calling for the city to raise the top band of council tax.

[47] In May 2019, Denyer unsuccessfully stood as one of the Green candidates for South West England in the European Parliament Election.

[57] The elections saw her refusing to share a platform with the UKIP candidate Carl Benjamin regarding a hustings planned to be held at the University of Bristol, arguing that "while the protection of free speech is important, we have to guard against the far-right taking advantage of it".

[60] The Greens participated in the Unite to Remain campaign,[16][61] leading to discussion as to whether she or the standing Labour MP Thangam Debbonaire was the more convincing candidate for pro-EU voters.

[62][63][18][64] Denyer argued that polls predicting that Debbonaire would receive 60% of the vote didn't take into account the Liberal Democrats standing down in favour of the Greens.

[72] Midway through the 2024 United Kingdom general election campaign, in a poll from YouGov, 53% of Green supporters did not recognise a photograph of Denyer.

[5] Denyer was criticised in July 2024 for owning a gas boiler in her home, despite the Green Party’s strong support and lobbying for heat pumps.

[89] In 2024, the New Statesman named Denyer 50th in The Left Power List 2024, the magazine's "guide to the 50 most influential people in progressive politics".
