Methane pollution is increasing at the fastest rate in decades, according to a new report, and that's making it harder to turn the tide on climate change and protect public health. Oil and gas operations are the single biggest source of methane pollution.
Megan Kemp, director with Healthy Air and Water Colorado, said when operators release methane, they are also releasing other toxins into the air known as volatile organic compounds, or VOCs.
"Alongside methane, benzene and other VOCs can worsen asthma and other respiratory diseases, it can even increase the risk of heart attacks and cardiovascular diseases, the risk of cancer, it can cause immune system damage, and even developmental problems in children," she explained.
On hot summer days, methane and other VOCs combine with sunlight to create ground-level ozone pollution, which has plagued Colorado's Front Range for years, and has led the Environmental Protection Agency to charge the state as a severe violator of clean-air standards.
The Colorado Oil and Gas Association says operators have cut methane and other ozone-related pollution by at least 50%, through regulation and new technologies.
The report's researchers have called for immediate action to cut methane pollution to slow an accelerating climate crisis. Kemp believes state regulators can do more to limit methane emissions, which are more than 80 times more powerful at trapping heat in the atmosphere than CO2.
"So, in addition to this ozone formation, it is contributing to the acceleration of extreme heat, increased vector-borne illnesses, decreasing water supply, water quality, and the list goes on," she continued.
The U.S. is the leading producer of crude oil, which ramped up with new fracking technologies. The rise in fracking also tracks with the rise in global methane emissions. Kemp said while cutting emissions is critical for a future livable climate, more attention needs to be paid to communities that have long lived in the shadows of refineries and other polluters.
"It is in our state statute to minimize adverse impacts from oil and gas for disproportionately impacted communities. And we see time and time again that our regulatory agencies are not stepping up and meeting the mandate," Kemp explained.

As low-income households face the dual burden of weather extremes and high energy costs, energy efficiency is an increasingly important strategy for both climate mitigation and lower utility bills.
Passive House standards — which create a building envelope so tight that central heating and cooling systems may not be needed at all — promise to dramatically slash energy costs, and are starting to appear in “stretch codes” for buildings, including in Massachusetts, Illinois, Washington and New York.
And while some builders are balking at the initial up-front cost, other developers are embracing passive house metrics as a solution for affordable multifamily housing.
“We’re trying to make zero energy, high performing buildings that are healthy and low energy mainstream everywhere,” said Katrin Klingenberg, co-founder and executive director of Passive House Institute-U.S., or Phius.
Klingenberg says the additional work needed to meet an aggressive efficiency standard, is, in the long run, not that expensive. Constructing a building to passive standards is initially only about 3%-5% more expensive than building a conventional single family home, or 0%-3% more for multifamily construction, according to Phius.
“This is not rocket science… We’re just beefing up the envelope. We’re doing all the good building science, we’re doing all the healthy stuff. We’re downsizing the [heating and cooling] system, and now we need someone to optimize that process,” Klingenberg said.
Phius in practice and action
A Phius-certified building does not employ a conventional central heating and cooling system. Instead, it depends on an air-tight building envelope, highly efficient ventilation and strategically positioned, high-performance windows to exploit solar gain during both winter and summer and maximize indoor comfort.
The tight envelope for Phius buildings regulates indoor air temperature, which can be a literal lifesaver when power outages occur during extreme heat waves or cold snaps, said Doug Farr, founder and principal of architecture firm Farr Associates.
Farr pointed to the example of the Academy for Global Citizenship in Chicago, which was built to Phius standards.
“There was a really cold snap in January. Somehow the power went out [and the building] was without electricity for two or three days. And the internal temperature in the building dropped two degrees over three days.”
Farr said that example shows a clear benefit to high efficiency that justifies the cost.
“You talk about the ultimate resilience where you’re not going to die in a power outage either in the summer or the winter. You know, that’s pretty valuable.”
There is also a business case to be made for implementing Phius and other sustainability metrics into residential construction, such as lowered bills that can appeal to market-rate buyers and renters, and reduced long-term maintenance costs for building owners.
AJ Patton, founder and CEO of 548 Enterprise in Chicago, says in response to questions about how to convince developers to consider factors beyond the bottom line, simply, “they shouldn’t.”
Instead, he touts lower operating costs for energy-efficiency metrics rather than climate mitigation when he pitches his projects to his colleagues.
“I can’t sell people on climate change anymore,” he said. “If you don’t believe by now, the good Lord will catch you when He catch you.
“But if I can sell you on lowering your operating expenses, if I can sell you on the marketability, on the fact that your tenants will have 30%, 40% lower individual expenses, that’s a marketing angle from a developer owner, that’s what I push on my contemporaries,” Patton said. “And then that’s when they say, ‘if you’re telling the truth, and if your construction costs are not more significant than mine, then I’m sold.’”
Phius principles can require specialized materials and building practices, Klingenberg said. But practitioners are working toward finding ways to manage costs by sourcing domestically available materials rather than relying on imports.
“The more experienced an architect [or developer] gets, they understand that they can replace these specialized components with more generic materials and you can get the same effect,” Klingenberg said.
Patton is presently incorporating Phius principles as the lead developer for 3831 W Chicago Avenue, a mixed use development located on Chicago’s West Side. The project, billed as the largest passive house design project in the city to date, will cover an entire city block, incorporating approximately 60 mixed-income residential units and 9,000 sq ft of commercial and community space.
Another project, Sendero Verde, located in the East Harlem neighborhood of New York City, is the largest certified passive-house building in the United States with 709 units. Completed in April, Sendero Verde is designed to provide cool conditions in the summer and warmth during the winter — a vast improvement for the low-income and formerly unhoused individuals and families who live there.
Barriers and potential solutions
Even without large upfront building cost premiums and with the increased impact of economies of scale, improved technology and materials, many developers still feel constrained to cut costs, Farr said.
“There’s entire segments of the development spectrum in housing, even in multifamily housing in Chicago, where if you’re a developer of rental housing time and again … they feel like they have no choice but to keep things as the construction as cheap as possible because their competitors all do. And then, some architecture firms only work with those ‘powerless’ developers and they get code-compliant buildings.”
But subsidies, such as federal low income housing credits, IRS tax breaks and resources from the Department of Energy also provide a means for developers to square the circle, especially for projects aimed toward very low-income residents.
Nonetheless, making the numbers work often requires taking a long-term view of development, according to Brian Nowak, principal at Sweetgrass Design Studio in Minnesota. Nowak was the designer for Hillcrest Village, an affordable housing development in Northfield that does not utilize Phius building metrics, but does incorporate net-zero energy usage standards.
“It’s an investment over time, to build resilient, energy-efficient housing,” he told the Energy News Network in June 2023.
“That should be everyone’s goal. And if we don’t, for example, it affects our school system. It affects the employers at Northfield having people that are readily available to come in and fill the jobs that are needed.
“That’s a significant long-term benefit of a project like this. And that is not just your monthly rents on the building; it’s the cost of the utilities as well. When those utilities include your electricity and your heating and cooling that’s a really big deal.”
Developers like Patton are determined to incorporate sustainability metrics into affordable housing and commercial developments both because it’s good business and because it’s the right thing to do.
“I’m not going to solve every issue. I’m going to focus on clean air, clean water, and lowering people’s utility bills. That’s my focus. I’m not going to design the greatest architectural building. I’m not even interested in hiring those type of architects.
“I had a lived experience of having my heat cut off in the middle of winter. I don’t want that to ever happen to anybody I know ever again,” Patton said. “So if I can lower somebody’s cost of living, that’s my sole focus. And there’s been a boatload of buy-in from that, because those are historically [not] things [present] in the communities I invest in.”

When the sharing economy took off in the 2010s and upended entire industries, the firmest proponents of the model heralded it as an economic revolution that would help slash emissions. Of all the ideas that emerged and dissolved over the years, shareable electric scooters seemed to possess the most promise for climate. Almost anyone with a smartphone and a credit card could grab one and ride it down the block or across town, eschewing automobiles.
Yet, as the industry matures and Lime - which, with operations in 280 cities worldwide, is the biggest player - moves further into its eighth year, researchers have shown that the eco-friendly dreams of shared micromobility have not materialized without problems. The true climate benefits of these fleets depends upon how companies deploy and manage them, and safety remains a concern as injuries climb. But industry leaders appear intent on ensuring their scooters are as sustainable and safe as possible.
"It's really important as a company that has set a net-zero target by 2030," said Andrew Savage, Lime's head of sustainability, "that we walk the walk, and that we do everything we can to inspire the industries around us to decarbonize as well."
The sustainability of shared micromobility is an active area of research in a fast-changing industry. Ultimately, researchers see two factors that determine the overall climate impact of e-scooters: how users ride them, and how operators manage them from manufacturing to disposal.
A recent survey of the latest research questioned whether the sharing economy is inherently sustainable, including a particular look at e-scooters. The survey found many researchers were repeatedly concerned with the question: "If riders hadn't rented a scooter, how would they have gotten to their destination?" If someone would have walked instead of ridden, that person increased the emissions associated with that trip. But several studies, including one by the Portland Bureau of Transportation and another, funded by Lime, by a German research institute, have found that though anywhere from a third to well over half of scooter users would have walked instead, enough other trips that would have been taken by car were not. Shared scooters, on the whole, help reduce overall transportation emissions - often preventing 20 grams of CO2 emissions per mile ridden on a scooter.
The picture in urban landscapes, however, can get slightly more complicated when researchers consider how those providing the scooters retrieve them to charge, repair, or redistribute them to where people are likely to use them. Colin Murphy, director of research and consulting at the Shared Use Mobility Center, said that when operators use big cargo vans to manage their fleets, they can negate some of the emissions savings from users.
To address this, Savage said the company is improving its fleet logistics to reduce overall emissions. Lime's scooters and bikes are now equipped with larger, swappable battery packs, which means they need to be charged less often, and when they do, fleet workers can drive around with a trunk full of battery packs rather than taking the scooter back to a warehouse, effectively cutting logistics emissions in half while ensuring scooters are available more often. Savage said the company has also bought over 140 electric vans to support those operations. Though that's 10 times the number Lime had a few years ago, it's still only one van for every two cities it operates in.
Savage said Lime is also working to reduce its impacts in other ways. For instance, in North America, "once vehicles arrive at port," Savage said, "we are now using emissions-free trucking to get those to our distribution centers." Beyond that, the company has designed a modular bike that makes it easier to swap out damaged parts, and parts that are beyond repair are often sent for recycling. And it has worked with one company, Gomi, to salvage cells from partially damaged batteries for use in what it says are zero-waste Bluetooth speakers.
But perhaps the most concerning hurdle the industry faces is also the one over which it has, in reality, the least direct control: rider safety. One study, released earlier this year by researchers at the University of California, Los Angeles, found that from 2017 to 2020 serious injuries for scooter riders rose threefold, just as revenues for the scooter-sharing industry shot from $10 million to nearly $450 million. This trend only continued into 2021 and 2022, with micromobility injuries increasing an average of 23 percent every year. And these weren't just scrapes and bruises. The UCLA-led study found that scooter users were, compared to cyclists, more likely to end up with a broken arm or leg, require surgery, or even end up paralyzed. The researchers suspect that may be due, among other things, to riders often lacking safety gear.
Lime insists that it places safety first. But with most American cities designed to promote cars over all other forms of transit, the health of scooter users is, like those of pedestrians and cyclists, at risk once wheels hit pavement. Perhaps it should be no surprise that of the 30 people killed in 2018 while riding an e-scooter, 80 percent were struck by a car. This is why, if society wants to move away from cars as the default, Kailai Wang, who studies urban mobility at the University of Houston, believes urban areas need to invest in upgraded infrastructure like protected bike lanes that can make roads safer for non-automotive transport.
Of course, cars aren't the only dangers e-scooter users, like cyclists, face. Poor road and sidewalk conditions can lead to serious injuries. And sometimes riders are their own enemy. According to some studies, first-time riders and late-night riders face elevated risks. Murphy, said that these are two areas where scooter-sharing platforms and local policymakers can step in.
For instance, he said that operators could artificially limit the max speed of a scooter during a user's first few rides as they grow accustomed to the vehicle. In other cases, many cities prohibit e-scooter rides in the wee hours to prevent misuse. But "to the degree that these vehicles provide a real kind of transportation lifeline for some people," Murphy said, "that's almost when they're at their most important." For someone who ends a late shift after bus services end, an e-scooter might actually be their best, or only, means of getting home. This reality led the Chicago City Council, for example, to consider revising its own late-night prohibition.
As long as people have access to one of these vehicles when they need one, and a safe lane in which to ride it, shared micromobility can help cities move away from car-dependent transportation, slashing emissions in the process, by shifting transit from something material and energy-intensive to something low-impact and electric.

A new report is providing a roadmap for policymakers and industry leaders to shape the future of Pennsylvania's clean energy landscape.
The findings from the new Union Energy coalition examine various programs to create high-quality union jobs in areas such as transportation, industry, agriculture and infrastructure while addressing climate change.
Rob Bair, president of the Pennsylvania Building and Construction Trades Council and secretary-treasurer of Union Energy, said Pennsylvania is a major energy producer and leading the way in the clean energy transition. He added there are opportunities beyond wind and solar.
"We can spur hydrogen production and create construction jobs and permanent jobs," Bair asserted. "We can start utilizing the 435 low head dams in Pennsylvania for hydropower that are sitting doing nothing. We have 28,000 abandoned wells, and a lot of them could be used for geothermal power."
Some of the report's recommendations include developing high-speed rail infrastructure, which could create more than 173,000 jobs in the Mid-Atlantic north region by 2035.
Union Energy collaborates with other unions on apprenticeship programs, and Bair noted they assist in establishing programs to accelerate the process of workforce development.
"An apprenticeship is a fantastic way to train young men and women," Bair explained. "Because you're getting paid while you're learning, but you're not just getting thrown into a job saying, 'OK, we hired you. Here it is.' So we're helping them learn how to build really good registered apprenticeship programs."
Union Energy is a two-year project with the AFL-CIO and the Pennsylvania Building Trades. The report was commissioned by Cornell University's Climate Jobs Institute and showed funding from the Inflation Reduction Act, Bipartisan Infrastructure Investment and Jobs Act and the Build Back Better plan are available to create permanent union jobs to set up the next generation of workers to be middle class.
