Our “Ditching Old Diesel Trucks” report just got an update!

Since we published our original report in 2025, diesel prices have surged, making cleaner alternatives more economically attractive.

RNG is emerging as a particularly compelling option. Because it’s disconnected from diesel price volatility, fleets can reap major fuel savings. For a Class 8 RNG truck, the ~$75,000 upfront premium could now be paid back in 1.3-2.8 years, compared with the 3-7 years in our original analysis.

Opinion: Why the US Needs to Invest in Renewable Natural Gas

Energy Vision Founder Joanna Underwood was featured this week in Sustainable Views, a specialist service from The Financial Times.

This new commentary piece makes the following points:

The Iran war and disruption of the Strait of Hormuz have driven up energy and fertilizer prices, highlighting the risks of US reliance on volatile global fossil fuel markets.

The US, spending less that it has spent on this war, could dramatically expand domestic production of renewable natural gas and fertilizer made from organic wastes.

Doing so would not only strengthen energy and food security but also substantially reduce the methane emissions that would be emitted by these wastes, making it a powerful tool for slowing near-term global warming.

Check out our latest op-ed, published today on E+E Leader: “SAF Prices Shouldn’t Rise with Conventional Jet Fuel. There’s a Better Way to Make SAF Cheaper and More Available”!

There are grand aspirations for sustainable aviation fuel (SAF) to help decarbonize aviation. SAF holds a lot of promise but also faces major structural obstacles, including being artificially tied to global oil prices.

Energy Vision Director of Research and Publications Michael Lerner dives into how these volatile prices needlessly distort the current SAF market. He argues there’s a far better way to make SAF that can be cheaper and much more available than what the market has seen: using renewable natural gas (RNG) as a feedstock, which is not coupled to global oil prices and has many other advantages.

Check out Energy Vision’s Summer 2026 News Blast!

This edition highlights the latest developments shaping the future of sustainable maritime fuels and food waste reduction. Here’s a sneak peak:

Maritime report: Our latest report on sustainable maritime fuels finds that global maritime trade is expected to increase 40-115% above 2020 levels by 2050, creating an urgent need for cleaner fuel solutions. Renewable diesel, bioLNG, and biomethanol offer the most practical near-term pathways to significantly reducing emissions.

Founder’s Column: Joanna Underwood reflects on the record-breaking heatwave that swept across the US during the nation’s 250th anniversary. The milestone serves as a reminder of the need to accelerate the transition to more sustainable fuel options.

A school’s food waste digester: Rye Country Day School in Rye, NY has eliminated its food waste via a small-scale anaerobic digester. The leftover digestate has been certified for organic use as plant food, and is being distributed to students, families, and employees for their home gardens and garden clubs.

New York State food waste policy: New York’s Food Date Labeling Act will eliminate “sell by” labels, leaving only “best if used by” and “use by” to indicate the quality and safety date of each food item. It passed the legislature in part thanks to Energy Vision’s outreach, and now awaits the governor’s signature.

Renewable Natural Gas: An Assessment of Arizona’s Resource Potential, Opportunities and Obstacles

We are pleased to share a new Energy Vision white paper co-authored by the Center for an Arizona Carbon Neutral Economy (AzCaNE).

Arizona has significant opportunities to expand renewable natural gas (RNG) production and use across four primary categories: landfill gas, and anaerobic digestion (AD) of animal manure, wastewater, and food waste. Today, large landfill facilities and concentrated dairy operations offer the greatest near-term potential for methane capture and RNG production, while wastewater treatment facilities and food waste provide smaller but valuable complementary opportunities.

In Arizona, the benefits of RNG production extend beyond methane emissions reductions. AD systems that process animal manure and food waste can help conserve water by reusing treated liquid streams and recovering water throughout the process. In a state facing chronic water scarcity, these water conservation benefits strengthen the case for expanding RNG development.

To help accelerate RNG development and use in Arizona, Energy Vision recommends adopting policies that have been successful in other states. These include rewarding low-emitting fuels based on verified lifecycle GHG reductions, enabling “book-and-claim” accounting for pipeline-injected RNG with safeguards against double counting, and supporting some utility procurement of RNG with clear cost caps and public reporting to protect ratepayers.

Incentivizing Diary Digesters in Washington: Energy Vision’s Roadmap and the State’s Latest Actions

EV’s December 2025 Report “Market Challenges & Opportunities for Dairy Anaerobic Digestion (AD) In Washington State” assessed how Washington could stimulate change in its dairy sector while meeting two critical climate objectives: the international goal to slash methane emissions 30% by 2030 and the state’s goal to reduce total GHG emissions 45% by 2030.

Washington is one of the top 10 states for milk production, presenting a key opportunity to deploy anaerobic digesters (ADs) in the state’s dairies. At present, there are only 5 operational dairy ADs in Washington, and EV calculates that another 80 dairies statewide could support anaerobic digestion.

The construction of these ADs could cut the state’s manure methane emissions by 75% — reducing about 1.2M metric tons of CO2 equivalent — a key opportunity to meet the state’s climate goals. While current market conditions and policies are not compelling enough to spur this level of investment, we came up with 10 recommendations to accelerate a dairy AD buildout in Washington.

Inspired by the success of key policies in California, EV suggests Washington dramatically step up its grants, subsidize AD maintenance, and provide loans through its new Green Bank. Washington could also tap into the $3B accrued from its Cap and Invest program to fund these incentives. Another opportunity for dairy ADs is co-digesting manure with pre-consumer food waste, which aligns with the state’s goal of cutting 75% of landfilled organic waste.

Following the report’s release, Washington has further emphasized the importance of building dairy ADs to help meet the state's climate goals through:

The state’s Comprehensive Climate Action Plan, published in April 2026, which calls to “Install more anaerobic digesters” and “Incentivize the conversion of biogas from on-farm anaerobic digesters into clean energy.”
Seven grants from the Department of Commerce, totaling $13.8M, awarded to build/maintain dairy ADs and capture-flare systems on dairy farms between 2025-2027.
An expected second round of AD grants later this year ($10M allocated) and another $40M in dairy AD grants after 2027.

EV’s Director of Research & Publications Michael Lerner spoke about these topics on July 7th at the first of the Anaerobic Digester Webinar Series, "The Role of Digesters in Meeting Greenhouse Gas Emissions Goals and the Critical Role of Carbon Crediting in Economic Viability". The series, hosted by WSU and funded through the WA Legislature, is free to the public and explores the economic, regulatory, and technological aspects of implementing dairy AD in Washington, aiming to facilitate their buildout.

New York State recently took major strides in reforming its landmark climate law, the Climate Leadership and Community Protection Act (CLCPA). As part of a broader trend to accelerate real, on-the-ground climate and clean energy progress, Energy Vision has long advocated for making legislative changes to the CLCPA to more feasibly achieve its ambitious goals, and NYS has finally followed through on most of those recommendations, seven years after passage.

Some key changes include:

- Switching from a 20-year to a 100-year Global Warming Potential (GWP) accounting framework, in line with every other jurisdiction except Maryland (which uses both).

- No longer counting biogenic CO2 emissions toward the state’s greenhouse gas (GHG) inventory, following suit with the federal government, the Intergovernmental Panel on Climate Change (IPCC), and other leading jurisdictions around the world.

- No longer counting emissions associated with out-of-state fossil fuel production and distribution in the state’s GHG inventory, also in line with best practice.

These changes, passed as part of the annual budget law in late May, remove major obstacles to investment and set the stage for scaling up the bio-economy in NYS. In recognition of just how hard it is to decarbonize the state’s economy quickly and cost-effectively, the CLCPA’s emissions reductions goals were revised as well. Specifically, the requirement of a 40% reduction by 2030 was changed to a 60% reduction by 2040, while maintaining the goal of at least an 85% reduction by 2050.

While the CLCPA now recognizes the biogenic carbon cycle by distinguishing biogenic CO2 emissions from fossil CO2 emissions, the amended law does not specifically include the anaerobic digestion (AD) of organic waste as a form of renewable energy.

This may sound like a small detail, but it has major ramifications for AD in the state. Until/unless NYS clarifies that AD is renewable, the state likely won’t be able to directly procure renewable natural gas (RNG) for its zero-emissions electricity grid, nor will it be able to provide grants or other incentives for RNG like it does for solar, wind, etc. RNG should be part of a broader strategy to incentivize and accelerate all clean energy production and deployment across New York.

The implementation of additional rapid-decarbonization policies such as a Clean Fuel Standard, an RNG blending requirement for statewide gas supply, expanded grants and incentives for clean energy projects, and the forthcoming Cap and Invest program would further support New York in achieving its long-term climate goals.

New Clean Fuel Standard in Hawaii!

On May 6th, Hawaii became the fifth state to pass a Clean Fuel Standard (CFS)! This new CFS aims to reduce the carbon intensity of transportation fuels used in Hawaii by at least 50% by 2045, relative to 2019 levels. The law sets a baseline target of at least a 10% reduction by 2035 and directs the Hawaii Department of Transportation to implement new regulations for the program by January 1, 2028.

The program will primarily tackle carbon emissions from cars and trucks. Aircraft, trains, military vehicles, and interstate waterborne vessels are exempt from the requirements, but may voluntarily opt in to generate credits. Alternative fuel users can also opt in to earn credits by displacing fossil fuels in heating, cooling, and temporary power generation.

Following in the footsteps of California, Oregon, Washington State, and New Mexico, Hawaii’s CFS will disincentivize fossil fuels like gasoline and diesel while incentivizing cleaner alternatives such as electricity and renewable natural gas (RNG). Produced by capturing methane emissions from decomposing organic waste, RNG can significantly reduce lifecycle greenhouse gas emissions compared to fossil fuels.

Energy Vision has long advocated for more states to adopt Clean Fuel Standards as a proven way to cut transportation-related emissions at virtually no government expense. We are excited to see further progress on this front!

Energy Vision’s Director of Research and Publications, Michael Lerner, had an op-ed published in the Journal of Commerce!

“War-driven energy shock makes case for more alternative fuels”

The war in Iran and the blockade of the Strait of Hormuz have increased volatility in bunker fuel prices, with average VLSFO costs worldwide rising from $540/mt in early February to over $930/mt today.

And even as the fate of the International Maritime Organization’s proposed Net-Zero Framework remains up in the air, the case for adopting low carbon shipping fuels is getting stronger by the day.

Energy Vision’s Joanna Underwood has published an Op-Ed in Environment + Energy Leader!

New York’s Climate Leadership and Community Protection Act (CLCPA) largely ignores organic waste as a major and ongoing source of methane emissions, despite being one of the most potent greenhouse gases.

This oversight can be corrected through two crucial changes:

Updating CLCPA’s definition of renewable energy to include anaerobic digestion of organic waste.
Adopting lifecycle carbon accounting.

Together, these proposed changes could help close critical policy gaps and unlock scalable climate solutions that are available today.

RNG captured from organic waste could slash emissions and boost grid resilience. Two changes to New York's climate law would make it happen.
