A new report documenting the impact of fossil fuel-powered appliances on air quality makes the case that Maryland will need to take additional steps to meet its climate goals.
The study authored by a group of environmental organizations looked at home and commercial use of fossil fuels in HVAC systems and water heaters - and found that in Maryland, such equipment emits more than three times the amount of health-harming nitrogen oxides as all the state's power plants combined.
The nonprofit Chesapeake Climate Action Network contributed to the report, and Maryland Director Jamie DeMarco said pollution from fossil fuel-powered appliances is worse in cities.
"Every gas furnace vents outside, so it's a little smokestack," said DeMarco. "And when you have a lot of homes together, there's a lot of smokestacks. So urban areas have more concentrated air pollution outdoors from indoor space and water heating."
Study authors are calling on the state to enact air-quality equipment standards similar to those in California, that would phase out the sale of natural gas-fired furnaces and water heaters and promote more efficient alternatives such as heat pumps.
The report estimates pollution from fossil-fuel equipment in Maryland is responsible for more than 6,000 lost workdays per year and more than $1.3 billion in health impacts.
Researchers also forecast that newer, more efficient appliances would reduce costs, estimating that 98% of households in the state would save money on energy bills each month.
DeMarco said a new state standard for home appliances would not impact existing equipment, but would be implemented at the point of sale.
"Air-quality equipment standards would not come into anybody's home and require you to change what you have," said DeMarco. "It's just at the point when you need to replace the equipment. An air-quality equipment standard would just ensure that you are buying the best product that is going to heat your home most efficiently, most affordably, while not contributing to air pollution in Maryland."
In decades past, the criticism of heat pumps was their inability to continue operating in extreme cold.
But DeMarco said technology improvements in recent years have brought units to market that can still heat homes with outside temperatures at minus 22 degrees.
"These are not your grandparents' heat pumps," said DeMarco. "One of the states with the highest adoption of heat pumps for heating homes is Maine. Because you just don't have the gas pipelines to reach all those rural homes. But you can install heat pumps, and it heats even in Maine winters."
Heat pumps also cool homes in summer months and use 29% less electricity vs central AC.

Under the federal Clean Air Act, Kentucky is required to keep haze air pollution under control in Mammoth Cave National Park.
Critics said the state's current plan falls short. Coal-fired power plants are the driving cause of air pollution impairing visibility in the Commonwealth, according to the National Parks Conservation Association.
Ashley Wilmes, executive director of the Kentucky Resources Council, said the state's current Draft Regional Haze State Implementation Plan only considers two facilities as significant pollution emitters, despite evidence there are more.
"There has to be a detailed analysis of additional major polluters in Kentucky that are contributing to this haze," Wilmes asserted. "They did not do this analysis for other major coal plants, including Ghent and Mill Creek, Trimble Station and others."
The Kentucky Energy and Environment Cabinet hears virtual public comments on the plan tomorrow at 10 a.m. ET.
Ulla Reeves, clean air program director for the National Parks Conservation Association, said several major polluters in the region are contributing to poor air quality.
"We see in Kentucky that Mammoth Cave is actually one of the most polluted national parks in the entire country," Reeves pointed out. "It is surrounded by polluting facilities."
Bryon Gary, program attorney for the council, said advocates are asking the state to include additional pollutants and facilities, and address environmental justice impacts to surrounding communities. He added residents' input will be considered by the Environmental Protection Agency.
"The public will have the opportunity to give those comments," Gary noted. "Then at some later point, the Energy Environment Cabinet will develop a written response to comments that will be submitted to EPA, along with their final state implementation plan."
Exposure to the air pollution particles triggering haze can cause breathing problems, lung cancer, heart attacks and low birth weight in newborn babies, according to the Centers for Disease Control and Prevention.

California air-quality regulators today are expected to adopt new fees for big polluters and rules to encourage large buildings to switch equipment from gas to zero-emission electric models.
Fifteen clean-air advocacy groups are rallying in front of the Southern California Air Quality Management Board in Diamond Bar today, urging passage of the new rules.
Kimberly Orbe, senior conservation program manager for the Sierra Club's Angeles chapter, said the transition would cover gas-fired water heaters, boilers and process heaters.
"Fossil fuel appliances are responsible for 10% of the emissions from stationary sources in our region," she said, "so that's really huge."
Opponents of the change include SoCalGas and industry groups representing dry cleaners and restauranteurs.
When burned, natural gas emits harmful smog-forming air pollution and greenhouse gases that fuel climate change. The So Cal Air Quality Management District's new pollution fee program would require large industrial polluters to pay to support regional clean-air efforts. The Sierra Club estimates this could raise about $25 million a year.
According to the American Lung Association, the Los Angeles/Long Beach area has the most high-ozone days of any metropolitan area in the country. Orbe said that's why advocacy groups have been pressing for stronger air-quality standards for years.
"Our region is burdened by an overwhelming amount of pollution - from oil drilling, from refineries, from the ports, from the warehouses, freeways," she said. "So, we want to make sure that we're passing strong rules to ensure that we continue to clean up our air, year after year."
The board is also expected to set a hearing date to consider new rules requiring zero-emissions technologies in the rail yards to combat diesel pollution from trains.

Leaders in Michigan are marking the historic new clean car standards, finalized by the Environmental Protection Agency.
The final rule, Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles, was announced in March.
Michigan leaders are celebrating the move as a positive step in the fight against climate change.
State Rep. Jasper Martus, D-Flushing, said many people think of climate change and creating good jobs as two separate issues, but he said he believes the two go hand-in-hand.
"When we pursue policies that combat climate change, such as investing in electric vehicles, having higher standards for the vehicles that are produced here in Michigan and the United States," said Martus, "we can do it in such a way that creates good paying jobs."
The new standards will phase in over model years 2027 through 2032.
Martus said in addition to creating new jobs, the transition to electric vehicles will also decrease pain at the pump resulting from sky high gas prices.
He added he believes it's time for companies that make EVs to make their pitch to the public.
"We're not to the point now where everything is going to be electric vehicles overnight," said Martus. "We're not even at the point where everything could be a hybrid overnight. But we're beginning that process of these companies making electric vehicles need to make the pitch."
Martus added that as EV makers pitch their product, consumers will eventually see the prices of the vehicles come down - making them just as competitive, if not more so, than traditional vehicles.
