Chancellor Rishi Sunak is being urged to use the Budget to change the financial system to better protect the environment.
One group wants him to impose a carbon tax and use the proceeds to protect the poor from high energy bills.
A second petition is calling for Bank of England rules to encourage banks not to invest in fossil fuels.
Mr Sunak is expected anyway to update the Bank’s mandate to include a greater focus on climate.
But campaigners want the new wording to stop the Bank from supporting fossil fuel firms through schemes such as its £20bn corporate bond purchase programme, which involves buying debt issued by firms such as Shell and BP.
