Hell is shopping for eco poop bags.
As much as I’m aware that blaming the climate crisis on individual consumer choices is a favorite smokescreen of large corporations and fossil fuel companies, it still totally kills me to buy single-use plastic bags. So when my household recently ran out of the 900 black disposable litter bags we’d bought on Wirecutter’s recommendation eons ago, I decided to be a Good Person and replace them with the most environmentally friendly option I could find. I mean, how hard could it be?
Hoo boy.
What started out as a naïve quest to find the greenest pet waste receptacle has become my Joker origin story. It’s turned me into Mark Ruffalo in Dark Water, except instead of taking on Dupont, I’m hounding companies with names like The Original Poop Bag and Doggy Do Good for the chemical makeup of their “green” bags. I’ve been red-pilled on advanced recycling. And, worst of all, I still haven’t actually bought a replacement — because the entire “green,” “biodegradable,” “plant-based,” “compostable” pet waste bag industry is built on misdirections, half-truths, and outright lies.
This might seem like a ridiculous thing to have spent my time obsessing over (and I don’t entirely disagree with you). But the greenwashing and obfuscation around these bags is part of a bigger story. Plastics are the fossil fuel industry’s last stand. The renewable energy transition, albeit in fits and starts, is here. Seeing the writing on the wall, companies like ExxonMobil, Shell, and Saudi Aramco are heavily investing in petrochemicals, which are used to make plastic and are expected to make up half of oil demand growth between now and 2050, according to the International Energy Agency (IEA). As Armco president and CEO Amin Nasser has reassured his cohorts, oil demand from petrochemicals is expected to remain high “no matter which energy transition scenario plays out.”
But I’m getting ahead of myself.
This story starts with much cuter villains: my cats.
Meet the adorable antiheroes of this story, Marinka and Virginia:
This whole piece is just an excuse to show you a picture of my cats.Jeva Lange/Heatmap
These two cutie pies don’t know it, but they diligently contribute to the 5.1 million tons of feces produced by America’s dogs and cats every year. One estimate of the dog sector alone found that disposing of all that waste adds some 500 million single-use bags to U.S. landfills annually.
The evils of single-use plastic bags have already been drilled into most of our heads by now: They take years to break down and when they do, they don’t decompose but rather turn into tiny microplastics that end up in the soil, waterways, food chain, and even our bloodstreams and breast milk. There is one seemingly great and trendy way to get around this: compostable bags!
Alas, if something sounds too good to be true, it is. For one thing, the “compostable” claims made by eco-friendly pet companies are wildly misleading. Though brands like to imply that their bags decompose and disappear like any other yard waste, these products only break down within a year under the extremely specific conditions of a commercial composting facility — very, very few of which even accept pet waste in the first place. As a result, the FTC has flagged that “compostable claims for these products are generally untrue.”

...and why you should always read the fine print.Chewy.com
Companies love to exploit consumers’ lack of knowledge around these terms and processes, though, and are mostly free to do so since the language isn’t strongly regulated. Often brands will brag that their compostable bags meet the “ASTM D6400 standard,” which just means they meet the industrial composting standard — again, pretty useless for us in this context. (Touting the ASTM D6400 standard is also often a way for brands to hide that their bags are made with virgin fossil fuels … more on that soon).
The bigger question when it comes to composting pet waste is, do we even want to? Dogs and cats are meat eaters, which means their poop contains parasites and bacteria like roundworms and hookworms, which can last for years in the soil and even be passed onto humans if used as a fertilizer for edible plants. While maybe this doesn’t sound like it could be that big of a problem, it is: “A study by the Bureau of Sanitation found that 60% of the bacteria in a Marina Del Rey, [California,] waterway was because of animals, domesticated and feral,” the Los Angeles Times reports. Gross.
This is one time you’ll ever hear me say that dog people have it better, though. Done correctly, dog owners actually can home compost dog waste if they’re so inclined. That said, a major downside of compostable bags is that they seem to lead some people to the impression that they can litter trails and parks with their “green” bags since the bags will eventually “go away.” As previously discussed: No, they won’t.
Cat waste, however, never basically should end up in your garden: Felines carry the parasite Toxoplasma gondii, which can be passed onto humans via compost but has been found to kill wildlife, including the sea otters in California. “Toxoplasma infections contribute to the deaths of 8 percent of otters that are found dead, and is the primary cause of death in 3 percent,” The New York Times explains. While feral cats used to be blamed for spreading the parasite, new evidence shows house cats almost certainly are, too — through their waste.
So compostable pet waste bags are out. As one municipality put it, dog and cat poop should be treated like what it is: not a fertilizer, but a pollutant. That means it needs to be sequestered, one way or another, in a landfill.
Just going to nip this one in the bud. For the same reason that composting pet waste isn’t advisable due to parasites and bacteria in four-legged meat-eaters’ feces, flushable pet waste bags and litter aren’t a safe or responsible choice, either.
Many waste treatment facilities don’t kill Toxoplasma, so putting cat poop in the toilet just expedites its journey into your local waterway. Indeed, in responding to an utterly unhinged email I sent them about cat waste, the California Association of Sanitation Agencies confirmed that “the only thing that should be flushed is human waste and toilet paper.”
Biodegradable pet waste bags are what radicalized me.
At first glance, these bags appear to be the best option. A number of them come on the recommendation of the sustainability website Treehugger. The product websites usually feature blogs full of reassuring information about how harmful plastic waste is, or boast 1% for the Planet certifications, or mention something about being made of cornstarch. Even the bags are green!
And almost all of them, despite their lofty claims, are made using virgin fossil fuels.
Polybutylene Adipate Terephthalate, or “PBAT,” is a biodegradable plastic made from the petrochemicals butanediol, purified terephthalic acid (PTA), and adipic acid. Translation: Fossil fuels must be extracted in order to make any bag that contains PBAT, which is virtually all of them.
Companies are exceptionally sneaky about this, though. Some of the brands boast outright about using PBAT as a traditional plastic alternative, likely assuming customers have no idea what the acronym means and won’t bother looking it up. Yet as Alice Judge, a former veterinarian and co-founder of the U.K.-based sustainable pet website Pet Impact, found in her own investigation, PBAT rarely makes up less than 60% of these supposedly “plant-based” pet waste bags. “There is some really concerning greenwashing and outright lying” going on in the industry, she told me. “We’ve found brands that are very big, reputable brands even saying explicitly ‘100% plant-based’ and in the same sentence saying ‘made from cornstarch and PBAT.’”
"Zero plastic" — but contains a fossil fuel-derived chemical called PBAT.Sirwaggingtons.com
PBAT is typically combined with cornstarch or sugarcane, so a “plant-based” bag advertising those ingredients can often be a tip-off that a fossil fuel product is also involved. Additionally, companies will frequently flag on their packaging that they meet the ASTM D6400 or BPI standards, though these have no provisions against certifying biodegradable products that contain PBAT.
Pet waste bag companies appear to go out of their way to avoid these admissions. Doggy Do Good, a popular sustainable pet waste company, told me in an email they use a “proprietary bio-based material” for “60.9% of the composition of their bags” — that is, the expected amount of PBAT — and added that “this fully biodegradable copolymer is an excellent alternative to polyethylene.” When I pressed to clarify if their proprietary “biodegradable copolymer” in question was PBAT, as I suspected, they stopped replying to my emails. The Original Poop Bag, another green bag company, didn’t answer me at all when I asked if their bags contained the fossil fuel product.
Despite these avoidance tactics, biodegradable bag companies aren’t using PBAT because they nefariously want to ruin the planet. It’s just the dirty secret of the pet waste bag business. As Judge explained in a blog post, “All poo bags have to include PBAT for strength and structure. If they were 100% plant-based, they would turn to mush very quickly when wet, lack strength, and tear easily (some qualities you really don’t want in a poo bag!).”
Fair enough. It’s the lack of transparency that is the problem: Most of these companies are selling fossil fuel-based products to customers who think they’re buying bags made from corn.
What's the other 62%?Doggydogood.com
Ultimately, there are two ways to think about the impact of the pet waste bags you buy: the impact of the materials used to make them and the impact of their disposal. If the latter is your biggest concern — what happens to bags after they’ve been used — biodegradable and “plant-based” bags are still probably the best, if imperfect, option available on the market. You can throw them in the trash (where they belong because again, pet poop is a pollutant) but also know at least that they’ll eventually biodegrade in a landfill (it should be noted, though, that everything is technically biodegradable, and the word means nothing without specification about the timeline and conditions).
From an “input” perspective — what the bags are made of, and how — biodegradable and “plant-based” bags are a little less exciting. They require less virgin fossil fuel than buying a bag entirely made out of traditional single-use plastic, though some research has suggested there is “no real difference in lifetime emissions between” products made with traditional plastic and those made from bioplastics. By another estimate, greenhouse gas emissions “are typically higher for bio-based plastics than recycled and virgin plastics” because “corn requires large amounts of energy, space, and water to grow industrially” and “turning the corn starch (once cultivated) into a polymer requires considerable energy.”
There is one major exception to all of this: Avoid “oxo-biodegradable” products. These are banned in the EU because they break down, sure — but into toxic microplastics.
Though they’re comparatively rare, you can find “recycled plastic” pet waste bags on the market. They apparently cut down on virgin fossil fuels by recycling plastic that’s already been extracted. (Judge’s company, Pet Impact, sells its own poo bag made from recycled ocean plastic, oyster shell waste, and “about 25 to 30%” virgin fossil fuels).
Even 100% recycled materials have their problems.
But while recycled plastic sounds great, it has — you guessed it — its own complications.
“Chemical” or “advanced” plastic recycling is the current sweetheart of the oil and gas industry, despite evidence that recycling plastic isn’t nearly as good as it’s chalked up to be. For one thing, the process of converting old plastics into new plastics is incredibly emissions-intensive and thus requires the burning of fossil fuels to generate the required energy. The recycling process can also spew cancer-causing chemicals into the air that disproportionately poison low-income communities of color, like those in “Cancer Alley.”
This is a problem that stretches far beyond the humble poo bags: Hundreds of companies now sell everything from clothes to shoes to shampoo bottles on the boast that they’re made from recycled plastics. Yet “by feigning ‘recycling’ (really, downcycling) of plastic pollution, companies can divert attention from their role in perpetuating this crisis while pulling in profits,” stresses the advocacy group Plastic Pollution Coalition. Recycled plastic can be just another smokescreen when what’s really needed is a reduction of single-use plastics altogether.
But it was reducing single-use plastics that got me into this whole mess in the first place.
In March 2020, a month when nothing else of note was happening, New York City banned single-use carryout plastic bags, joining San Francisco and a number of other towns around the country. But like many pet owners, grocery store plastic bags had been our go-to litter scooping bags. As we became more conscious of single-use plastics in some parts of our lives, it led us to buy … a bunch of single-use plastics to use for our pets.
As the pandemic wore on, my husband and I eventually decided to fly across the country with Marinka and Virginia in order to be with our families. There, my stepmother introduced us to a revolutionary new poop bag. It didn’t require the extraction of any new fossil fuels, and while it doesn’t break down in a landfill, it also won’t poison any otters.
The name of this holy grail of poop bags? Trash.
Empty bread bags can become the perfect chutes for scoops of litter. Plastic packaging gets a second life as a final resting place for kitty unmentionables. Bags of dry cat food, once exhausted, can be refilled.
This isn’t a perfect solution, either (for example, “produce bags aren’t engineered to be particularly durable, nor to hold in liquids or odors,” Wirecutter warns with the confidence of experience). But if I’ve learned anything in this mad, scatological journey, it’s that there is no perfect solution. What satisfies one person’s environmental concerns — about greenhouse gas emissions, fossil fuel extraction, or waste and pollution — might not satisfy someone else’s. And at a certain point, you have to make a choice, and likely a compromise, and then move on to focusing on the things that make a bigger difference, like what you drive, where you get your power from, or what you eat.
All this is to say, the trash method works for me because it makes single-use plastics destined for the landfill anyway into twice-use plastics. And at least it allows me not to think about cat poop anymore.
I think I’ve done enough of that to last me a lifetime.

A conversation with Biao Gong of Morningstar
This week’s conversation is with Biao Gong, an analyst with Morningstar who this week published an analysis looking at the credit risks associated with offshore wind projects. Obviously I wanted to talk to him about the situation in the U.S., whether it’s still a place investors consider open for business, and if our country’s actions impact the behavior of others.
The following conversation has been lightly edited for clarity.
What led you to write this analysis?
What prompted me was our experience in assigning [private] ratings to offshore wind projects in Europe and wanted to figure out what was different [for rating] with onshore and offshore wind. It was the result of our recent work, which is private, but we’ve seen the trend – a lot of the big players in the offshore wind space are kind of trying to partner up with private equity firms to sell their interests, their operating offshore wind assets. But to raise that they’ll need credit ratings and we’ve seen those transactions. This is a growing area in Europe, because Europe has to rely on offshore wind to achieve its climate goals and secure their energy independence.
The report goes through risks in many ways, including challenging conditions for construction. Tell me about the challenges that offshore wind faces specifically as an investment risk.
The principle behind offshore wind is so different than onshore wind. You’re converting wind energy to electricity but obviously there are a bunch of areas where we believe it is riskier. That doesn’t mean you can’t fund those projects but you need additional mitigants.
This includes construction risk. It can take three to five years to complete an offshore wind project. The marine condition, the climate condition, you can’t do that [work] throughout the year and you need specialized vehicles, helicopters, crews that are so labor intensive. That’s versus onshore, which is pre-fabricated where you have a foundation and assemble it. Once you have an idea of the geotechnical conditions, the risk is just less.
There’s also the permitting process, which can be very challenging. How do you not interrupt the marine ecosystem? That’s something the regulators pay attention to. It’s definitely more than an onshore project, which means you need other mitigants for the lender to feel comfortable.
With respect to the permitting risk, how much of that is the risk of opposition from vacation towns, environmentalists, fisheries?
To be honest, we usually come in after all the critical permitting is in place, before money is given by a lender, but I also think that on the government’s side, in Europe at least, they probably have to encourage the development. And to put out an auction for an area you can build an offshore wind project, they must’ve gone through their own assessment, right? They can’t put out something that they also think may hurt an ecosystem, but that’s my speculation.
A country that did examine the impacts and offer lots of ocean floor for offshore is the U.S. What’s your take on offshore wind development in our country?
Once again, because we’re a rating agency, we don’t have much insight into early stage projects. But with that, our view is pretty gloomy. It’s like, if you haven’t started a project in the U.S., no one is going to buy it. There’s a bunch of projects already under construction, and there was the Empire Wind stop order that was lifted. I think that’s positive, but only to a degree, right? It just means this project under construction can probably go ahead. Those things will go ahead and have really strong developers with strong balance sheets. But they’re going to face additional headwinds, too, because of tariffs – that’s a different story.
We don’t see anything else going ahead.
Does the U.S. behaving this way impact the view you have for offshore wind in other countries, or is this an isolated thing?
It’s very isolated. Europe is just going full-steam ahead because the advantage here is you can build a wind farm that provides 2 or 3 gigawatts – that’s just massive. China, too. The U.S. is very different – and not just offshore. The entire renewables sector. We could revisit the U.S. four or five years from today, but [the U.S.] is going to be pretty difficult for the renewables sector.
What I’m hearing from developers and CEOs about the renewable energy industry after the Inflation Reduction Act
As the Senate deliberates gutting the Inflation Reduction Act’s clean electricity tax credits, renewable energy developers and industry insiders are split about how bad things might get for the sector. But the consensus is that things will undoubtedly get worse.
Almost everyone I talked to insisted that solar and wind projects further along in construction would be insulated from an IRA repeal. Some even argued that spiking energy demand and other macro tailwinds might buffer the wind and solar industries from the demolition of the law.
But between the lines, and beneath the talking points and hopium, executives are fretting that lots of future investments are in jeopardy. And the most pessimistic take: almost all projects will have their balance sheets and time-tables impacted in some way that’ll at minimum increase their budget costs.
“It’s hard to imagine, if the legislation passes in its current form, that it wouldn’t impact all projects,” said Rob Collier, CEO of renewable energy transaction platform LevelTen.
Even industry analysts with the gloomiest views of the repeal say there’s plenty of projects that will keep chugging along and might even become more valuable to investors if they’re close enough to construction or operation. This aligns with recent analysis from BloombergNEF, which found the House bill would diminish our nation’s renewables build-out – but not entirely end its pace.
“The more useful way to break down which project may be hit the hardest is where the projects are going to fall in their development life-cycle,” Collier said. “Projects that have either started construction or have the ability to start construction … are going to very likely rise in terms of their appeal and attractiveness and those projects will be at a premium, if they’re able to skate through the legislative risk and qualify for tax credits.”
There is a more optimistic industry view that believes increased project costs will just be passed along to consumers via higher electricity prices. The American people will in essence have to pick up the tab where the federal tax code left it. Optimists also cite the increased use of power purchase agreements, or PPAs, between renewables developers and entities who need a lot of electricity, like big tech companies. By signing these PPAs, buyers are subsidizing the construction of projects but also insulating themselves from the risk of rising electricity prices.
The most bullish perspective I heard was from Nick Cohen, the CEO of Doral Renewables, who told me deals like these combined with rising premiums for quick energy on the grid may obviate lost credits in a “zero-incentive environment.”
“It’s not the end of the world,” Cohen told me. “If you’re in construction or you’re going to be in construction very soon, you’re fine.”
But Collier called Cohen’s prediction an “experiment” in customers’ willingness to pay for new energy: “If we’re talking about 40%, 50%, 60% of a project’s capital stack now being at risk because of tax credits, those are pretty large price increases.”
I spoke to multiple companies that have been inking massive deals as this legislation has progressed — although many were not nearly as sanguine about the industry’s future prospects as Doral. Like rPlus Energies, which disclosed last week that it closed a commitment for more than $500 million in tax equity investments for a solar and storage project in Utah. rPlus CEO Luigi Resta told me that the legislation “certainly has posed concern from our investors and from the organization” but the project was so far along that the tax equity investment market wasn’t phased by the bill.
“Many people in my company, myself included, have been doing this for more than 20 years. We’ve seen the starts and stops related to ITC and PTC in solar and wind, in multiple cycles, and this feels like another cycle,” Resta told me. “When the IRA passed, everybody was exuberant. And now the runway looks like it may have a cliff. But for us, our mantra since the beginning of the year has been ‘proceed with caution, preserve and protect.’”
However, crucially, it is important to focus on how that caution looks: Resta told me the company has completely paused new contracting while the company is completing the projects it is currently developing.
One government affairs representative for a large and prominent U.S. renewables developer, who spoke on the condition of anonymity to preserve relationships, told me that “whatever rollback occurs will just result in higher electricity prices over time.” In the near term, the only language that would truly gut projects in progress today would be “foreign entity of concern” restrictions that would broadly impact any component even remotely connected to Chinese industries. Similar language all but kneecapped the entire IRA electric vehicle consumer credit.
“It included definitions of what it means to be a foreign company that were really vague,” the government affairs representative said. “Anyone who does any business with China essentially can’t benefit from the credit. That was a really challenging outcome from the House that hopefully the Senate is going to fix.” If this definition became law, this source said, it would be the final straw that “freezes investment” in renewable energy projects.
Ultimately, after speaking to CEO after CEO this week, I’ve been left with an impression that business activity in renewables hasn’t really subsided after the House bill passed, and that it’ll be the Senate bill that undoubtedly defines the future of renewable energy for years to come.
Whether that chamber remains the “cooling saucer” it once was will be the decider.
