On the same day, activists dressed up as "corpses" and lay on the floor in a protest at the Shrewsbury town centre Barclays branch, accusing the bank of putting profits "above life itself".
In response to protests in the firm's banks up and down the country, a Barclays spokesperson said: “We are determined to play our part in addressing the urgent and complex challenge of climate change.
"In March 2020 we were one of the first banks to set an ambition to become net zero by 2050, across all of our direct and indirect emissions, and we committed to align all of our financing activities with the goals and timelines of the Paris Agreement.
"We have a three-part strategy to turn that ambition into action: achieving net zero operations, reducing our financed emissions, and financing the transition. In practice, this means we have set 2030 targets to reduce our financed emissions in four of the highest emitting sectors in our financing portfolio, with additional 2025 targets for the two highest-emitting sectors – energy and power.
"We have also provided over £80bn of green financing and we are investing our own capital – £175m – into innovative, green start-ups."
