In this week’s blog, we focus on natural gas and greenhouse gas emissions.
Gaining a better understanding of greenhouse emissions released from natural gas production and delivery systems helps clarify how the proper deployment of natural gas can deliver significant environmental benefits. Join us in taking a closer look at the numbers.
Industry-wide Natural Gas Emissions are Low and Declining
The U.S. Environmental Protection Agency (EPA) made further updates to its estimates of methane emissions in its Inventory of U.S. Greenhouse Gas (GHG) Emissions and Sinks: 1990–2018 (“Inventory”), released in April 2020. The Inventory incorporates new data available from studies on emissions as well as the EPA’s own Greenhouse Gas Reporting Program (GHGRP).
The Inventory found that industry-wide methane emissions¹ as a rate of natural gas production were 1 percent. The ratio of methane emissions per unit of natural gas produced has declined continuously during the past several decades, dropping 48 percent since 1990.
U.S. Methane Emissions per Mcf of Gas Produced ²
The inventory also confirmed that natural gas distribution systems have a small emissions footprint that continues to decline. Distribution systems emit less than 0.1 percent of produced natural gas annually, a decline of 73 percent from 1990 to 2017 even as U.S. natural gas utility companies added more than 730,000 miles of pipeline to serve 19 million more customers,
increases of 50 and 36 percent respectively, and natural gas production increased by 50 percent.
The bottom line: New control technologies, replacement of old cast iron and bare steel pipes, and better industry practices have contributed to significant emissions reductions, even as annual natural gas production and consumption have hit record highs.
U.S. Methane Emissions from Natural Gas Distribution Systems
Regionally, Emissions are Already Lower and Expected to Decline Even Faster
In the basins from which the Pacific Northwest sources most of its natural gas, policymakers and regulators have taken action to further decrease methane emissions from upstream operations. Effective January 2020 in BC, the source of about two-thirds of our region’s natural gas, the BC Oil and Gas Commission (BC OGC) has committed to reduce methane emissions from upstream oil and gas operations by 45 percent by 2025 relative to 2014 levels, targeting everything from compressor seals to storage tanks. The BC approach is expected to reduce methane emissions by 10.9 megatonnes (10.9 million metric tons) of CO2 equivalent over a 10-year period, the equivalent of taking 390,000 cars off the road each year.³ In addition, BC’s natural gas transmission sector is expected to reduce its emissions by 40 to 45 percent below 2012 levels by 2050 under the Canadian federal Methane Regulation, which also came into force in January 2020. Like the BC OGC, the federal Methane Regulation is focused on reducing emissions from fugitives and venting.
In 2014, Colorado (which provides much of our region’s Rockies’ gas, about one-third of our supply overall) approved the first methane regulations in the U.S. requiring energy companies to reduce methane emissions from oil and natural gas operations by routinely checking their oil and natural gas wells—both new and existing—statewide, and immediately addressing any leaks. The regulations go beyond those of the EPA, which apply only to new or modified operations, according to the Environmental Defense Fund, which helped craft Colorado’s regulations.
Where does the PNW get it’s natural gas?
By 2016, field surveys of oil and gas equipment by the Colorado Department of Public Health and Environment (CDPHE) found a 75 percent drop in the number of sites where methane leaks were detected compared to similar surveys conducted prior to the regulations taking effect, said Will Allison, former director of the department’s Air Pollution Control Division. By 2018, Garry Kaufman, the division’s new director, said, “Colorado’s program has reduced emissions of methane and volatile organic compounds from the oil and gas sector by hundreds of thousands of tons per year, while still allowing for growth in this important economic resource for Colorado.”
As a result, gas pipelines serving the Northwest have the lowest methane emissions on the continent and will continue to improve.
Regional Natural Gas Emissions are Small Relative to Other Sectors
Overall, direct use of natural gas for space and water heating in homes and commercial buildings in the Pacific Northwest accounts for just eight percent of total regional GHG emissions (see pie chart). The transportation sector (trucking, fleets, personal vehicles, public transit, etc.) produces the largest share of regional emissions (42 percent). The “other” category in the chart includes agriculture, forest practices, waste streams (landfills, wastewater treatment), building heat from fuels other than natural gas, oil and gas extraction (BC only), and industrial emissions not related to natural gas combustion.
¹Industry-wide, or “lifecycle” emissions, as defined by the EPA, include natural gas field production, processing, transmission and storage, and distribution.
²Includes methane emissions from petroleum production based on the natural gas fraction of total energy content produced from oil wells.

In today’s blog, we’ll discuss natural gas pricing.
The commodity cost of natural gas has plummeted with the surge in supply over the last decade (see Figure 1 below), saving Northwest consumers across all economic sectors hundreds of millions of dollars. Commodity prices are expected to remain below $4/Dth through 2050 (see Figure 2). High demand, coupled with infrastructure constraints, may periodically cause short-lived regional price volatility.
Figure 1. Historical Natural Gas Prices

Figure 2. Natural Gas Price Forecast Comparisons
NOTES: Price forecasts reflect the existence of and an ongoing expectation for robust natural gas supplies throughout the forecast period (2029) and beyond.
The Northwest Power and Conservation Council (NPCC) forecasts natural gas prices at trading hubs where the Pacific Northwest sources its gas: AECO and Sumas for natural gas originating in Alberta and British Columbia, and Opal for gas produced in the U.S. Rocky Mountain states of Colorado, Utah, and Wyoming.
The price of natural gas coming from the supply areas upon which the Pacific Northwest relies is typically lower than the North American benchmark at Henry Hub in Lousiana.
One of the primary reasons the Pacific Northwest has such an advantage in natural gas pricing relative to other parts of the U.S. is the region’s direct access to multiple production basins. In particular, the Pacific Northwest is the nearest market to the vast supply resources located in western Canada. When combined with an already well-developed and interconnected pipeline grid, gas shippers and utilities can quickly secure gas from the area with the lowest daily price and react quickly to re-route supplies when there have been disruptions.

It has turned out to be a hot summer on the West Coast. In California, we’ve seen 3 million people lose power with rolling blackouts because the state didn’t have enough reliable energy available to fill the void when renewable energy production there fell off a cliff.
My heart goes out to those caught up in the blackouts. It’s a reminder to those of us in the Northwest, that we need to maintain a diverse energy system that uses all sources of energy for optimum reliability.
Natural gas is a critical part of that system. It is the cleanest fossil fuel and provides reliable and affordable energy whenever it’s needed. It is uniquely capable of generating electricity to power your air conditioner when the wind isn’t blowing, or the sun isn’t shining. And if the power is out, natural gas can be used to cook or heat water for your shower or laundry.
Not only does natural gas contribute to a clean energy future by supporting intermittent renewable resources like wind and solar energy, but it is becoming increasingly renewable itself.
Renewable natural gas (RNG) is methane produced when materials like wood, food, and other organic waste decompose. Instead of being released directly into the atmosphere the gas is captured and converted into a clean energy source. RNG is being advanced through partnerships with foresters, farmers, and local governments and Northwest utilities are bringing more of it into their energy mix.
For reliability and renewability, natural gas and renewable natural gas are sources of energy that are vital to the future and enjoy broad support. According to a recent poll, more than 70% of Pacific Northwesterners don’t want natural gas to be banned. They understand the need for reliable, affordable energy to address climate change.
We have to work together to achieve a sustainable energy future. Natural gas and renewable natural gas aren’t the only answer, but they are an essential part of the picture. It’s up to all of us to keep the momentum going so that no one has to endure blackouts tomorrow.
The Value of Natural Gas in the Pacific Northwest
Natural gas is a crucial part of the Pacific Northwest’s energy mix providing heat and power to 10 million people and more than 300,000 businesses across the region. The direct use of natural gas for cooking, heating, and producing a variety of goods (e.g. toilet paper, cement, steel, glass, french fries, etc.) helps reduce global and regional emissions paving the way to a cleaner environment for future generations. In order improve the public’s understanding of the vital role of natural gas, the NWGA will produce a series of blogs to help readers understand how the natural gas industry works, how it differs from other energy sources, and how one size fits all policies affect energy choice and affordability for the region’s residents and the businesses many of them work for.
What does natural gas offer to the region?
- Warmth and comfort to 10 million people
- Efficient and affordable space heating, water heating, and heat for cooking and laundry (gas heat is about one-third the cost of electric heat in the Northwest)
- More than half of the total energy consumed in the region – either used directly for space and water heat or in industrial processes or as gas-generated electricity. (Excludes transportation uses.)
- A low carbon footprint – natural gas used for space and water heat in 3.2 million homes and more than 300,000 non-industrial businesses accounts for less than 10 percent of the region’s total carbon emissions, according to EIA data and state and provincial emissions inventories
- 128,000 miles of installed pipeline infrastructure that safely and reliably delivers energy, supplemented by underground and above-ground storage facilities capable of delivering up to 40 percent of required energy during the coldest days
- An invaluable input to some industrial processes for which there is no suitable substitute, including glass recycling and the manufacture of perlite (a common soil additive), steel and aluminum, paper products and food processing, among many others
- An alternate fuel source for medium and heavy-duty vehicles is both more economical and cleaner than diesel engines.
- Reliable 24/7 electricity production to replace retired coal plant generation and balance the region’s growing sources of intermittent renewable power, such as wind and solar
And our source of natural gas is increasingly renewable itself – market forces and government policy are driving the development of renewable natural gas, which transforms human and agricultural waste into useful energy. This provides even greater prospects for a cleaner mix of natural gas resources to contribute to our energy and environmental future.
Let’s start with some basics: where do we get our natural gas in the Pacific Northwest?
The Pacific Northwest’s natural gas comes from supply basins in Northern British Columbia and Alberta, Wyoming and Western Colorado, and Northwest New Mexico (the Western Canadian Sedimentary Basin, the Rocky Mountain Basin, and the San Juan Basin respectively). British Columbia and Alberta provide two-thirds of the region’s natural gas and Wyoming, Colorado, and New Mexico supply the remaining one-third. This gas is moved to British Columbia, Washington, Oregon, and Idaho by a network of inter-connected interstate pipelines.
The ability to draw gas supply from three areas provides consumers in the Pacific Northwest stability in pricing and reliability. For instance, a rupture in the Enbridge pipeline in British Columbia in 2018 impacted the ability to move Canadian gas south to the U.S., raising the price of Canadian gas. To compensate, Northwest gas utilities and gas shippers drew more from the San Juan Basin in New Mexico, which is very low-cost gas, thereby reducing the potential price impacts to consumers while the Enbridge pipeline was repaired and returned to service.
The inter-connected gas system in the Pacific Northwest also means the security of supply in the future. While U.S. Rocky Mountain and San Juan production is forecast to remain relatively flat through 2040, production in the Western Canadian Sedimentary Basin is projected to grow. This dynamic will help ensure continued access to a reliable and low-cost energy source.
BC Drives Projected 35% WCSB Production Growth from 2020-2040
Notes: WCSB production is forecast to decline for a few years, before growing to 21 Bcf/day by 2040 to meet expected rising demand for LNG exports. Most of that growth will come from the Montney formation that spans BC and Alberta.
Rocky Mountain Production Predicted to Remain Flat
Notes: As shown, Rockies’ production is generally flat through 2040. The San Juan Basin in northwest New Mexico is located below the Piceance play shown in the map above and is the southern terminus of the Williams NW Pipeline that serves the Pacific Northwest.
Compared to some areas of the United States and many countries, the Pacific Northwest is fortunate to have large nearby supply basins and a developed pipeline infrastructure to deliver gas safely and efficiently, and which can react to supply disruptions.
In our next segment, we’ll examine gas prices.
According to a Hearth, Patio and Barbecue Association survey, 73 percent of Americans will spend their Fourth of July holiday cooking outdoors. And natural gas is by far the most popular type of grill with 64 percent saying that’s their preference over charcoal or electric. Grilling is simply synonymous with the holiday.
Whether you’re planning a backyard barbeque for two or 20, Americans celebrate our country’s birthday by coming together as family, friends, and neighbors over a deliciously grilled meal and fireworks overhead. After prepping those burgers, hot dogs, chicken, salmon, oysters, and veggies, with the touch of a button, your gas grill is ready, and the clean-burning natural gas means less smoke dampening the mood.
In the beautiful Pacific Northwest, summer is the best time for sitting comfortably with friends or family in the backyard on a cool evening, with a warm fire and dinner sizzling on the grill — it’s pure pleasure.
Please stay safe this Fourth of July and enjoy that natural gas grill all summer long. Here are some helpful grilling tips:
- Place your grill at least 10 feet away from other objects, including the house, combustibles, and any shrubs or bushes.
- Always stay by the grill when cooking.
- Trim excess fat from meat and poultry to reduce grill flare-ups.
- Use the appropriate temperature to cook food, using lower temperatures for smaller items or larger cuts of meat that will take a long time.
- Place veggies on the edges of the grill to prevent overcooking.
- Before lighting the grill, apply non-stick spray on the grates for easy cleanup.

Americans are seeing firsthand the critical role that energy plays in meeting their daily needs and how the natural gas industry is #FuelingOurCommunities. The industry keeps delivering essential energy to the homes that have become offices, schools, and gyms, and the manufacturing facilities that continue to produce food, supplies, and personal protective equipment. It continues to fuel the frontline facilities where healthcare professionals are fighting COVID-19 every day. Providing affordable energy will boost an economic recovery that we all hope is on the horizon.
April heralds the advent of spring, including warmer weather and sunshine in the Pacific Northwest. Spring means more construction as well as tending to and planting gardens and other vegetation. Both activities involve digging.
That is why April is National Safe Digging Month. Before digging a hole more than 12 inches deep for any purpose, it is critical to “know what’s below”. Here is a guest blog from NW Natural that includes a terrific checklist to use before digging, whether you are a contractor or a homeowner. Most importantly, always call 811 before you dig.
DIGGING SAFELY THIS SPRING MORE IMPORTANT THAN EVER
News Release from NW Natural
Posted on FlashAlert: April 15th, 2020 9:48 AM
With more people at home doing yard projects, NW Natural reminds customers and contractors to call before digging
PORTLAND, Ore. — April marks National Safe Digging Month, a time to remember to call 811 to have underground utility lines located before digging in your yard, garden and beyond. This spring, that reminder is even more important with so many people in the Northwest staying home to stay healthy and potentially doing more yardwork than normal.
“If you or a contractor will be digging in your yard, make sure you call 811 at least two days ahead of time. Locate crews are still working during this time and abiding by all COVID-19 safety recommendations,” said Scott Gallegos, NW Natural’s damage prevention supervisor. “It’s a free service, and it’s the law.”
Nationally, the most common cause of a natural gas pipeline damage is someone accidentally digging into the pipe. Accidentally hitting an underground utility line can interrupt service to entire neighborhoods and lead to serious injuries, fines and costly repairs.
A helpful checklist to get started:
- Regardless of digging depth or familiarity with the property, make your request at least two business days before you plan to dig.
- Call 811 or use the free NW Natural Safety App.
- When you call 811, the Oregon Utility Notification Center notifies local utility companies of the intent to dig. Then a professional locator visits the site to mark the location of underground utility lines. The OUNC says the contractors who come out to mark buried lines will follow COVID-19 health safety precautions.
- Confirm with 811 that all lines have been marked.
- Consider moving your project location if it’s near utility line markings.
- If working with a contractor, confirm a call to 811 has been made. Don’t allow work to begin if lines aren’t marked.
If while you’re digging, you accidentally hit a gas line, report it immediately by calling 911 or NW Natural’s 24-hour emergency line at 800-882-3377. No damage is too small to report, even a small dent could weaken a natural gas line.
Always remember: Smell. Go. Let us know. If you smell natural gas, leave the area immediately, then call us at 800-882-3377 and we will come over to check things out. During COVID-19, NW Natural’s crews are following Centers for Disease Control (CDC) guidelines regarding social distancing, face covering and sanitizing protocols.

On April 16, Dan Kirschner will present the 2020 Gas Outlook on a live webinar. Register now by clicking here.
The Outlook continues to include current data and narrative on supply and prices, but more as background information because North American natural gas is projected to be an ample, low-priced commodity for the foreseeable future. However, the true value of the Outlook – aggregating and analyzing regional demand and delivery infrastructure data to inform policymakers and other stakeholders throughout the Northwest – remains the report’s core focus. Updated numbers and our forecast are presented in the Demand section and an expanded Capacity section, and in the appendices. We’ve also added two deeper dive articles exploring renewable natural gases and upstream methane emissions. The 2020 Gas Outlook is now available by clicking here.

The American Gas Association recently announced a partnership with Food Network star Amber Kelley to highlight natural gas as the tool of choice for chefs everywhere.
The simple turn of a knob on a gas range gives chefs the control they need to make anything they can imagine. There is no other technology that allows the control and high heat content that natural gas offers, and chefs around the world rely on our resource as a critical tool in the cooking craft.
The value of natural gas does not stop in professional kitchens. Homeowners across the world prefer natural gas as their go-to cooking resource. Aside from providing a superior cooking experience, a study by Market Strategies International showed that 90% of homebuyers say they’d pay $50,000 more for a home with natural gas appliances.
Sixteen-year-old Amber Kelley is a cookbook author, speaker, winner of Food Network Star Kids, and the host of her popular Youtube series Cook With Amber. From her appearances on The Disney Channel, E!, and the Today Show, to her endorsement from Jamie Oliver, Amber is inspiring a whole new generation of eaters to get in the kitchen and have fun. We are excited to hear from Amber on how natural gas supports her budding cooking career.
President Obama’s Secretary of Energy, Ernest Moniz, makes the case in the recent study“Pathways for Deep Decarbonization in California: Summary for Policymakers.”
“Clean fuels (e.g., renewable natural gas [RNG], hydrogen, biofuels) are critical clean energy pathways due to the enormous value of fuels in providing flexibility and reliability for energy systems. Fuels that are durable, storable, and easily transportable play a fundamental role in ensuring that all sectors can operate at the scale, timing, frequency, and levels of reliability that are required to meet social, economic, and stakeholder needs.
“The development of RNG in California has multiple tangible benefits: RNG is a carbon-neutral fuel; RNG diverts methane from being released into the atmosphere, enabling major emissions reductions from the difficult-to-decarbonize Industry and Agriculture sectors; and it leverages existing carbon infrastructure, potentially avoiding the costly stranding of these established systems and their associated workforces, as well as their time-consuming and costly replacement.”

On April 11 a much-anticipated report was released by The Energy Futures Initiative that analyzes the ways California can meet its aggressive low-carbon energy goals. The report, which was authored by a team led by President Obama’s former Energy Secretary Dr. Ernest J. Moniz, outlines an innovation agenda needed for deep decarbonization by 2050
The current HB 2020 proposal gives free credits to Oregon’s electric utilities in recognition of prior legislatively mandated green initiatives. It treats the more than two million Oregon residents and businesses who rely on natural gas for warmth, comfort and productive energy differently, ignoring the strides that Oregon LDCs and their customers have made in reducing emissions through system maintenance, modernization, and efficiency initiatives.
HB 2020 as currently composed is punitive to Oregon’s natural gas customers and unfair. The state is already seeing emissions reductions from the transition to and increasing reliance on natural gas as a cleaner, reliable fuel for generating electricity. The state is also seeing significant emissions-related benefits by virtue of the highly efficient direct use of natural gas for residential and commercial space and water heat. All natural gas utility customers should receive a fair share of allowances to mitigate rate impacts.

NWGA’s Climate Action Principles
Climate change is an important issue. States and provinces across the Pacific Northwest are developing policies to address climate change by reducing greenhouse gas emissions (GHGs). Natural gas – a clean, low-cost and abundant energy resource – is already reducing GHGs across North America and the region. In short, Northwest Gas Association members (NWGA) are committed to addressing climate change and maintain that natural gas is a climate solution.
