How Electric Vehicles are Going Mainstream (Again)

Electric vehicles are the future — but they’re not some far-off dream like flying cars. Rather, they represent the present as well as the possibilities to come. And they have a history that’s far deeper than you were likely aware. Learn more in this piece from Outdoor Delaware.

Emissions Reduction: Waste

The waste sector accounts for a small share of Delaware’s greenhouse gas emissions – about 3% in 2021 – but remains an important part of the state’s path to net-zero. Delaware manages all of its waste within state borders through landfills, recycling facilities and wastewater treatment plants. Emissions from this sector are primarily methane and

---

Emissions Reduction: Forests and Urban Trees

Forests and urban trees cover nearly one-third of Delaware’s land area and provide critical benefits for wildlife habitat, clean water and community well-being. They also support a strong forestry industry that employs nearly 2,000 people and contributes hundreds of millions of dollars to the state’s economy. At the same time, Delaware is losing more than

---

Emissions Reduction: Residential and Commercial Buildings

Delaware’s buildings are a central part of daily life and a growing source of greenhouse gas emissions. Because buildings vary widely in age, size and use, there is no single solution for reducing emissions. In 2021, the buildings sector produced about 14% of Delaware’s total emissions, with commercial buildings accounting for slightly more than homes.

---

Emissions Reduction: Industry

The industry sector is Delaware’s third-largest source of greenhouse gas emissions, accounting for 23.1% of statewide emissions in 2021. Although industrial emissions are 7.3% lower than in 2005, emissions are projected to grow without additional action. By 2050, industrial emissions are expected to overtake transportation as the state’s largest source of greenhouse gases, highlighting the

Emissions Reduction: Electricity Generation and Grid Infrastructure

Electricity generation is the second largest source of greenhouse gas emissions in Delaware, making up 26.9% of the state’s total in 2021. Emissions come from electricity generated both in-state and out-of-state which we use to light our homes and heat our businesses. A decarbonized electric grid serves as Delaware’s largest emissions reduction opportunity, as it

---

Emissions Reduction: Transportation

Transportation is Delaware’s largest source of greenhouse gas emissions, making up nearly 30% of the state’s total in 2021. Emissions come from cars, trucks, buses, planes, boats and off-road equipment. Reducing transportation emissions is key to reaching Delaware’s net-zero goals while improving air quality, public health and community resilience. Delaware

Toward Net-Zero Emissions by 2050

Reducing Delaware’s greenhouse gas emissions to nearly zero by 2050 is essential to avoid the worst impacts of climate change. The Climate Change Solutions Act of 2023 sets clear statewide emission reduction targets: a 50% reduction by 2030 and net-zero emissions by 2050, compared to a 2005 baseline. Reaching these goals, however, will require both

Emissions Reduction: Oceans and Wetlands

In Delaware, no one is ever more than a mile from water. The state’s 381 miles of coastline and nearly 300,000 acres of wetlands provide substantial economic, ecological and community benefits. These coastal and marine systems also play a critical role in Delaware’s climate strategy by storing and sequestering carbon in vegetation, sediments and submerged

---

Emissions Reduction: Agriculture

Agriculture is a vital part of Delaware’s economy and landscape, supporting farm families, food production and covering more than 40% of the state’s land area. In addition to its economic value, farmland plays an important role in addressing climate change by storing carbon in soils and vegetation. While agriculture contributes a relatively small share of

Delaware’s Push to Cut Diesel Emissions Improves Air Quality Statewide

Many communities across the United States face challenges related to air quality and respiratory health, especially as it pertains to emissions from diesel engines. In Delaware, transportation is a major contributor to pollution, producing 75% of the state’s nitrogen oxide emissions, which contribute to the formation of ground-level ozone. But Delaware is also taking advantage of a federal program to clean up diesel pollution, replacing and retrofitting older diesel vehicles like school buses and trash trucks.
