Delaware

Delaware’s greenhouse gas emissions have dropped by 23% from 2005-2021. The nation’s second-smallest state consumes much more energy than it produces, with most of it used by the industrial sector, as chemical manufacturing and petroleum refining are large contributors to the state’s GDP.

Progress by Policy Area

Enacted Enacted policies have been passed or established in a state by a governing body via legislation, executive orders, rules, regulations, and/or other program creation, and remain in effect.
In-progress In progress policies have been established in a state, but final regulations, rules, or plans are pending final approval. This also includes legislation and executive orders that require regulations to be put into effect.
Partially Enacted Partially enacted policies have been enacted in the state, but are missing one or more policy components. Dashboard policies cannot be considered partially enacted unless policy components are available.
Not Enacted Not enacted policies have not been passed or established in the state or are no longer in effect.

Glossary of Terms

The colored bars indicate the status for each policy on the Dashboard, viewed across seven policy areas.

Status	Policy	Policy Area	Policy Category	Year Enacted
Enacted	Residential Energy Codes Empty column The statewide energy code for residential construction is 2018 IECC. Establishing Policies Delaware State Energy Code (2020)	Buildings and Efficiency	Building Codes	2020
Enacted	Commercial Energy Codes Empty column The statewide energy code for commercial building construction is 2018 IECC and ASHRAE 90.1-2016. Establishing Policies Delaware State Energy Code (2020) HB 11 (2023)	Buildings and Efficiency	Building Codes	2020
Not Enacted	Stretch Building Energy Codes Empty column Stretch building energy codes are an optional, more stringent building code established by the state that local jurisdictions can adopt to require that newly constructed buildings are more efficient than the baseline state codes.	Buildings and Efficiency	Building Codes
Not Enacted	Appliance Standards Empty column Appliance standards set minimum energy and water conservation requirements for appliances and equipment.	Buildings and Efficiency	Building Standards
In-Progress	Building Performance Standards Empty column Delaware will receive $10M to develop and adopt a building performance standard through the federal Inflation Reduction Act Support for Building Energy Codes and Innovative Codes. Establishing Policies Inflation Reduction Act Support for Building Energy Codes and Innovative Codes – Round 2 (2024)	Buildings and Efficiency	Building Standards
Not Enacted	Clean Heat Standards Empty column Clean heat standards establish a performance standard requiring heat providers to deliver a gradually-increasing percentage of low-emission heating services to customers.	Buildings and Efficiency	Building Standards
Enacted	Energy Efficiency Resource Standards (EERS) Empty column Electric and gas utilities are subject to voluntary energy savings targets, which are determined by the Delaware Energy Efficiency Advisory Council. Establishing Policies SB 150 (2014)	Buildings and Efficiency	Building Efficiency	2014
Enacted	Property Assessed Clean Energy (PACE) Empty column Delaware has enacted commercial PACE-enabling legislation and has active programs. Establishing Policies SB 113 (2018)	Buildings and Efficiency	Building Efficiency	2018
Partially Enacted	Weatherization Funding Empty column The State Policy Opportunity Tracker (SPOT) breaks clean energy policies down into “components”, which are binary questions to evaluate policy quality. Higher quality policies have more of their SPOT components fulfilled. Establishing Policies SPOT - Weatherization Funding in Delaware Policy Components not-enacted not-enacted not-enacted enacted 1/4	Buildings and Efficiency	Building Efficiency
Not Enacted	All-Electric Buildings Empty column All-electric buildings policies require new buildings to be constructed with all-electric heating, cooling, and cooking systems to transition away from fossil-fuel use in buildings.	Buildings and Efficiency	Building Electrification
