Committee hears experts on electrification, health and limits of renewable gas

Portland’s Climate Resilience and Land Use Committee heard experts, public commenters and union representatives on Thursday about building electrification, methane’s health and climate impacts, and utilities’ plans to meet Oregon’s emissions rules.

Cara Saylor, director and staff attorney at the Green Energy Institute, told the committee the Oregon Department of Environmental Quality’s Climate Protection Program requires fossil-fuel suppliers to reduce greenhouse-gas emissions and that Northwest Natural’s Integrated Resource Plan (IRP) leans heavily on renewable natural gas (RNG), hydrogen and synthetic methane. Saylor said the utility’s present pathway raises cost and climate concerns and that the Public Utility Commission’s role is to weigh safety, reliability and fairness for ratepayers. "The PUC's mission is to ensure Oregonians have access to safe, reliable, and fairly priced utility services that advance state policy and promote the public interest," Saylor said.

Saylor and other presenters warned that biomethane remains methane and that leaks across production and pipeline systems release uncombusted methane, a greenhouse gas significantly more potent than carbon dioxide. Her presentation cited examples and noted Northwest Natural’s current RNG purchases and limited domestic supply: "As of 2023, [Northwest Natural] had produced 0.91% (of distribution) in renewable natural gas," she said when summarizing the company’s filings.

Melanie Plaut, an obstetrician who volunteers with Oregon Physicians for Social Responsibility, described health risks linked to indoor and outdoor combustion of gas. Plaut said gas cooking produces particulate matter and nitrogen oxides (NOx) and that studies link gas-stove use to increased respiratory symptoms and childhood asthma risk. "NOx, which you get from burning fuels, is bad for our health, both indoors and out," Plaut said.

Danny Noonan, a climate, energy and labor strategist with Breach Collective, argued utilities have used public-relations strategies to shift attention from electrification to alternative fuels. "Gas utilities are deploying a public relations strategy to impede regulation," Noonan said, summarizing his review of industry tactics and alleged use of front groups and litigation to slow policy changes.

Brian Stewart, a co-founder of Electra (an education volunteer group on electrification), told the committee that, in many cases, heat-pump technologies are the lowest-cost option for decarbonizing buildings and that multiple Pacific Northwest studies support electrification as the least-cost path to reduce building emissions.

Public testimony reflected divergent views. Climate advocates urged the city to expedite the Build Shift program, including tenant notification and data-gathering phases; Michaela McCormick of Extinction Rebellion said reducing methane is the fastest lever to slow near-term warming and urged action on tenant protections and energy-cost information. Diane Meissenhelder, speaking with Extinction Rebellion and the climate justice committee of the NAACP Portland branch, said the city had delayed modest Build Shift steps despite broad public support.

Representatives of Northwest Natural and labor unions urged caution. Catherine Williams, vice president for public affairs and sustainability at Northwest Natural, said the company was not given earlier outreach from the city on the committee item and asked to be included in future conversations. "We remain committed to working towards decarbonized systems and doing so in a way that is affordable and reliable for our customers," Williams told the committee. Howard Bell, business manager of OPEIU Local 11 and a former Northwest Natural employee, described pipeline modernization work and said he did not see the health harms described by others in his membership. Paul Elder, business manager of UA Local 290, said the region has technologies such as modern hydrogen pilots and urged that worker impacts be considered in transitions.

Committee members asked for lifecycle comparisons between electrification and alternatives. Presenters pointed to studies showing that, despite current grid generation emissions, heat-pump electrification typically reduces lifetime emissions compared with fossil-fuel end uses and that the electricity system is on a decarbonizing trajectory that increases electrification’s climate benefits over time. Councilors and panelists discussed possible local actions — including pilot projects replacing gas ranges in multifamily housing, tenant-notification for Build Shift, and using fee or reporting mechanisms where legally permitted — while noting regulatory authority over investor-owned utilities lies with the Oregon Public Utility Commission and DEQ.

No formal committee action was taken. The committee chair said staff will return with further materials at future meetings; the committee adjourned after agreeing to return to climate-friendly active-transportation and related items at the next meeting.
