Clean Heat Standards

A clean heat standard is a flexible policy tool that can require energy companies and heating appliance manufacturers to provide lower-emission heating services. These can include incrementally increasing emission reduction targets, performance-based targets, or more specific measures like mandating equipment manufacturers to sell a certain percentage of heat pumps each year. Clean heat standards encompass many different methods to deliver clean heating systems and can be tailored to the state-specific context and policymakers’ goals.
