As Michigan faces growing concerns over landfill emissions, researchers have launched the third phase of a major methane detection study which could bring much-needed answers.

Methane is one of the most potent greenhouse gases. The study, funded by the Environmental Research and Education Foundation, in partnership with FluxLab, tests methane detection technologies under real-world conditions. Earlier tests using drones, trucks, and towers showed big differences in detection. The third phase adds satellites, aircraft, overnight tests, and detailed weather and terrain data.

Bryan Staley, president and CEO of the foundation, shared the most surprising part of the study.

"Even just detecting the methane releases with these high-tech approaches was not as straightforward as we thought it would be," Staley explained. "The work that we have undertaken is helping advance that ball pretty quickly to get a better understanding of why that was happening and how we can make improvements with those technologies."

With more than 40 active landfills, Michigan ranks among the top 10 methane polluters, driven by high waste volumes and imports. A 2023 law boosted state efforts to improve methane capture and detection.

In the first two phases of the study, researchers tested at a closed landfill in Canada. Results showed no clear front-runner. The second phase incorporated weather and wind factors, with input from global tech providers. Those results are forthcoming.

Staley emphasized detecting methane where waste is placed is common but there are cases where its presence in a landfill raises concerns.

"It would be more concerning if you're seeing methane coming from an area of the landfill that is not receiving the waste," Staley pointed out. "Those are the kinds of emissions that should be detected and mitigated for and basically fixed."

The Environmental Protection Agency tracks landfill emissions but outdated methods may underestimate them by half. New rules also aim to curb underreported methane.

Environmental advocates are urging Washington state lawmakers to require cargo ships to plug in while in port.

The Port of Seattle will require all cruise ships to use shore power by 2027, but cargo ships face no such requirement. One ship idling for 40 hours emits 30 tons of carbon dioxide and sends 22 pounds of toxic soot into the air, which can harm port workers and adjacent neighborhoods.

Teresa Bui, climate policy director for the group Pacific Environment, said the sheer volume at regional ports requires action.

"The Northwest Seaport Alliance saw visits from 1,700 cargo vessels in 2023," Bui pointed out. "While the port is vital to the state economy, there is both a climate and a public health imperative to transition away from diesel and require these ships to plug in."

A 2023 study found diesel exhaust contributes more than 80% of the cancer risk from toxic air pollutants in the Seattle-Tacoma area.

Legislation to require shore power was introduced in the state House in January but did not make it out of committee. The legislation would apply to any terminal with more than 20 vessel visits per year. State lawmakers have committed more than $50 million toward port electrification.

With the third-largest container ship complex on the West Coast, Bui anticipates strong job creation.

"The additional benefit of requiring ships to plug in is there's job growth potential," Bui emphasized. "The TOTE terminal created 55 local jobs. IBEW supported this measure when it was introduced in the legislature."

A Maritime Administration estimate anticipates 100% shore power at the Port of Seattle would create hundreds of jobs over 30 years.

Environmental and wildlife conservation in Montana took hits during this year's state legislative session, including vetoes from the governor on bills that received bipartisan support.

Among bills Gov. Greg Gianforte vetoed was House Bill 477, which would have phased out some single-use Styrofoam food containers in favor of those made from Montana agricultural byproducts.

The bill's sponsor, Rep. Marilyn Marler, D-Missoula, called it "discouraging" when such a bipartisan effort is vetoed.

"Because it seems to me he did not listen to a wide variety of people, even in his own party," she said. "I think that with this particular bill, it just didn't send the right message about what our values are."

Tourism and recreation are important and growing industries in the state, and as Marler put it, "People don't come here to see trash."

Constituents can see how their lawmakers voted on conservation this session on the Montana Conservation Voters 2025 legislative scorecard.

Marler also voiced concern about weakening the Montana Environmental Policy Act, which was designed to uphold Montanans' constitutional right to a clean environment. While there was a win for habitat funding, Marler added she is seeing continued privatization of wildlife.

"It was not a great session for conservation and it was not a great session for Montana hunters," she explained. "It is becoming very hard to keep commercialization of wildlife off the books."

In renewable energy news, Gianforte vetoed the Montana Solar Shares Act, which would allow Montanans to buy shares in an energy-generating solar array. But a veto override poll for lawmakers is currently underway by mail.

Conservationists are celebrating the protection of five miles of river frontage along the White Salmon River. The 174-acre site was purchased by The Conservation Fund more than a decade after the removal of Condit Dam. The dam was breached in 2011, draining the former Northwestern Lake. The lakebed makes up much of the acquisition.

Gates Watson, vice president of The Conservation Fund, said the removal restored a 44-mile free-flowing river.

"The dam's presence had an impact on the migration route for fish, including regional salmon populations, and disrupted Yakama Nation's right to fish and gather and hunt along this land, and with this transition that will be restored," he explained.

The land was purchased from PacifiCorp, which operated the hydroelectric dam. The site is located in the ancestral territory of the Yakama Nation. The acquisition will be managed by The Conservation Fund temporarily, before being acquired by Yakama Nation on a permanent basis.

Planning for the long-term restoration brought together PacifiCorp, Yakama Nation, The Conservation Fund and an owners association whose cabins sat near the shores of Northwestern Lake. Cabin owners had been leasing land from PacifiCorp. Site surveys were conducted to establish individual lots so owners could acquire the land under their buildings.

Watson said site planning also included a conservation easement and more.

"The vision for the completed White Salmon Corridor project is five miles of connected riparian habitat and a foot trail along the White Salmon River that is owned and managed by Yakima Nation, restoring opportunities for tribal members to access the river and fish," he continued.

The river is a breeding habitat for steelhead, Chinook and coho salmon, and researchers have found juvenile fish are returning in strong numbers.
