James Alexander, CEO of the UK Sustainable Investment and Finance Association (UKSIF), said:
"The government's strategy for reducing emissions is a vital element of our economic positioning for the years ahead.
"Investors need certainty to allocate billions of pounds of capital to major low-carbon industries, and the carbon budget is an important demonstration of the UK's ongoing commitment to decarbonisation.
"The benefits of this private financing are being felt among thousands of small and medium-sized companies, which are playing their part in supply chains up and down the country.
"The government must continue to match these emissions benchmarks with policies that make it even more attractive to invest in the UK."
