The federal government needs to maximize existing funds to mitigate heat stress and ensure the equitable distribution of these resources to the most vulnerable households. Agencies could increase Low Income Home Energy Assistance Program (LIHEAP) funding allocations through incentives or by mandating a floor of benefits from these programs be distributed to a well-defined set of vulnerable households. This approach is similar to Justice40, the Biden administration’s signature environmental justice initiative that requires federal agencies to ensure a minimum allocation of 40% of program benefits are received by disadvantaged communities.
