The government wants to change how some private sector pensions are calculated.
The proposals mean millions of people would be likely to see lower increases to their pensions in retirement.
Pensions minister Steve Webb said there were plans to link pension payments to the typically slower-growing Consumer Prices Index (CPI) measure of inflation instead of using the RPI.
Accountants KPMG said this could reduce UK private sector pension liabilities by 10% or about £100bn.
