Enable consumers to retrofit existing buildings through access to financing

Beyond minimum standards, enabling consumers to retrofit existing buildings through access to financing will be essential to increasing efficiency improvements across more buildings. Governments can enable financing for retrofitting through exemptions to property purchase tax, known in some markets as stamp duty, or subsidized programs for adding insulation or replacing boilers (see Pillar 3: Buildings). They can also directly intervene with scrappage programs, offering consumers financial incentives for replacing their fossil heating system with a low-carbon one.
