It comes after the Government rowed back on some of its net zero policies, delaying a ban on the sale of new petrol and diesel cars from 2030 to 2035. In September the Prime Minister also said he would delay the ban on new oil-fired boilers from 2026 to 2035, and increase grants for heat pumps.
The Bank of England itself has faced criticism for its focus on climate change, a move promoted by former governor Mark Carney in departure from its traditional role of concentrating on interest rates and the state of the banking system.
But Ms Mann hit back at this criticism on Monday, arguing the Bank’s interest in climate change and net zero policies is critical because they affect inflation.
“Not only is it within my remit to respond to the macroeconomic effects of climate change, but, in my view, my remit requires me to do so,” she said.
“When climate change has macroeconomic effects – whether physical impacts from extreme weather events and higher average temperatures or transition effects associated with transforming to a net zero economy, including explicit implications for inflation – it becomes a concern for monetary policymakers, directly within a price stability mandate.
“That applies whether the monetary policymaker’s remit includes a reference to climate change or not.”
Ms Mann, who has consistently voted for higher interest rates than the majority of the nine-strong MPC, said net zero policies affect inflation as governments seek to push businesses away from established, but polluting production methods and into new greener methods.
But this means piling extra costs onto polluting businesses “presumably to be passed on fully or in part to consumers, which prompts the behavioural change needed to reduce emissions”.
Even if consumers themselves choose to buy less polluting products, the extra demand will push up prices until companies can boost the supply of the greener goods and services, Ms Mann added.
It came as economists at investment bank Morgan Stanley predicted the Bank of England will cut interest rates from the current level of 5.25pc from May next year, in a boost to mortgage borrowers.
