#BeatPlasticPollution and #WorldEnvironmentDay
June 5th, 2023, will mark the 50th anniversary of World Environment Day, which was established by the United Nations Environment Programme (UNEP) in 1973. This year, the event is anticipated to attract tens of millions of participants both online and through in-person activities, embodying the spirit of environmental advocacy.
Addressing plastic pollution
This year’s theme is focused on finding solutions to plastic pollution. The occasion underscores the consequences of actions and inaction taken by individuals, businesses, and governments in response to plastic pollution. It also highlights the pressing need to amplify these efforts and transition towards a circular economy. To assist in these efforts, a Beat Plastic Pollution Practical Guide is available, outlining steps to halt and reverse the detrimental effects of plastic pollution.
An urgent need
Our planet is in crisis, besieged by the overwhelming weight of plastic waste. Despite its numerous applications, plastic has become detrimental due to our dependence on single-use plastic products, which cause significant environmental and health issues.
As per the UN, globally, one million plastic bottles are bought every minute, up to five trillion plastic bags are used each year, and 400 million tonnes of plastic waste are produced annually. Approximately 36% of all plastic is used for packaging, including single-use items for food and beverage containers. Sadly, around 85% of these items end up in landfills or as unregulated waste. Less than 10% of the seven billion tonnes of plastic waste generated worldwide has been recycled. The most prevalent types of plastic waste found in the environment include cigarette butts, food wrappers, plastic bottles and caps, grocery bags, straws, and stirrers.
Environmental harm
Plastic waste can persist in the environment for centuries due to its durability and resistance to degradation. Nearly all single-use plastic products are manufactured from fossil fuels, contributing to the escalation of greenhouse gas emissions. Most plastic items merely break down into smaller microplastics, which can infiltrate the human body and accumulate in various organs. The impact of this phenomenon on human health remains largely unknown. Microplastics are now ubiquitous and are a part of the Earth’s fossil record. They have even led to the creation of a new marine microbial habitat, known as the “plastisphere.”
How you can help
Urge your local and national leaders to take decisive action by eliminating problematic plastic packaging, redesigning products for sustainability, and promoting transparency in sustainability information. Additionally, you can participate in beach or river clean-ups, shop sustainably, adopt a zero-waste lifestyle, advocate for change, choose sustainable fashion, and opt for plastic-free personal care products.

Cooks love their gadgets, from countertop slow cookers to instant-read thermometers. Now, there’s increasing interest in magnetic induction cooktops – surfaces that cook much faster than conventional stoves, without igniting a flame or heating an electric coil.
Some of this attention is overdue: Induction has long been popular in Europe and Asia, and it is more energy-efficient than standard stoves. But recent studies have also raised concerns about indoor air emissions from gas stoves.
Academic researchers and agencies such as the California Air Resources Board have reported that gas stoves can release hazardous air pollutants while they’re operating, and even when they’re turned off. A 2022 study by U.S. and Australian researchers estimates that nearly 13% of current childhood asthma cases in the U.S. are attributable to gas stove use.
On Jan. 9, 2023, the U.S. Consumer Product Safety Commission announced that it will consider measures to regulate hazardous emissions from gas stoves. The agency has not proposed specific steps yet, and said that any regulation will “involve a lengthy process.” On Jan. 11, CPSC Chair Alexander Hoehn-Saric further clarified that the agency was looking for ways to reduce indoor air quality hazards, but did not plan to ban gas stoves.
Natural gas has long been marketed as a clean fuel, but research on its health and environmental effects is calling that idea into question.
Respiratory effects
One of the main air pollutants commonly associated with using gas stoves is nitrogen dioxide, or NO₂, which is a byproduct of fuel combustion. Nitrogen dioxide exposures in homes have been associated with more severe asthma and increased use of rescue inhalers in children. This gas can also affect asthmatic adults, and it contributes to both the development and exacerbation of chronic obstructive pulmonary disease.
Nitrogen dioxide in homes comes both from outdoor air that infiltrates indoors and from indoor sources. Road traffic is the most significant outdoor source; unsurprisingly, levels are higher close to major roadways. Gas stoves often are the most substantial indoor source, with a greater contribution from large burners that run longer.
The gas industry’s position is that gas stoves are a minor source of indoor air pollutants. This is true in some homes, especially with respect to exposures averaged over months or years.
But there are many homes in which gas stoves contribute more to indoor nitrogen dioxide levels than pollution from outdoor sources does, especially for short-term “peak” exposures during cooking time. For example, a study in Southern California showed that around half of homes exceeded a health standard based on the highest hour of nitrogen dioxide concentrations, almost entirely because of indoor emissions.
How can one gas stove contribute more to your exposure than an entire highway full of vehicles? The answer is that outdoor pollution disperses over a large area, while indoor pollution concentrates in a small space.
Ventilation is an essential tool for improving indoor air quality in homes.
How much indoor pollution you get from a gas stove is affected by the structure of your home, which means that indoor environmental exposures to NO₂ are higher for some people than for others. People who live in larger homes, have working range hoods that vent to the outdoors and have well-ventilated homes in general will be less exposed than those in smaller homes with poorer ventilation.
But even larger homes can be affected by gas stove usage, especially since the air in the kitchen does not immediately mix with cleaner air elsewhere in the home. Using a range hood when cooking, or other ventilation strategies such as opening kitchen windows, can bring down concentrations dramatically.
Methane and hazardous air pollutants
Nitrogen dioxide is not the only pollutant of concern from gas stoves. Some pollution with potential impacts on human health and Earth’s climate occurs when stoves aren’t even running.
A 2022 study estimated that U.S. gas stoves not in use emit methane – a colorless, odorless gas that is the main component of natural gas – at a level that traps as much heat in the atmosphere as about 400,000 cars.
Some of these leaks can go undetected. Although gas distributors add an odorant to natural gas to ensure that people will smell leaks before there is an explosion risk, the smell may not be strong enough for residents to notice small leaks.
Some people also have a much stronger sense of smell than others. In particular, those who have lost their sense of smell – whether from COVID-19 or other causes – may not smell even large leaks. One recent study found that 5% of homes had leaks that owners had not detected that were large enough to require repair.
This same study showed that leaking natural gas contained multiple hazardous air pollutants, including benzene, a cancer-causing agent. While measured concentrations of benzene did not reach health thresholds of concern, the presence of these hazardous air pollutants could be problematic in homes with substantial leaks and poor ventilation.

Reasons to switch: Health and climate
So, if you live in a home with a gas stove, what should you do and when should you worry? First, do what you can to improve ventilation, such as running a range hood that vents to the outdoors and opening kitchen windows while cooking. This will help, but it won’t eliminate exposures, especially for household members who are in the kitchen while cooking takes place.
If you live in a smaller home or one with a smaller closed kitchen, and if someone in your home has a respiratory disease like asthma or chronic obstructive pulmonary disease, exposures may still be concerning even with good ventilation. Swapping out a gas stove for one that uses magnetic induction would eliminate this exposure while also providing climate benefits.
“I know people are hesitant about these kinds of induction stoves, but if you haven’t looked at one in 20 years, go take a look.” @evanhalper to a skeptical @GustavoArellano on the push by climate advocates to ditch gas stoves: https://t.co/NvZxqplO0E
There are multiple incentive programs to support gas stove changeovers, given their importance for slowing climate change. For example, the recently signed Inflation Reduction Act of 2022, which includes many provisions to address climate change, offers rebates for the purchase of high-efficiency electric appliances such as stoves.
Moving away from gas stoves is especially important if you are investing in home energy efficiency measures, whether you are doing it to take advantage of incentives, reduce energy costs or shrink your carbon footprint. Some weatherization steps can reduce air leakage to the outdoors, which in turn can increase indoor air pollution concentrations if residents don’t also improve kitchen ventilation.
In my view, even if you’re not driven to reduce your carbon footprint – or you’re just seeking ways to cook pasta faster – the opportunity to have cleaner air inside your home may be a strong motivator to make the switch.
This article has been updated to reflect the Jan. 11, 2023 statement from the Consumer Product Safety Commission that the agency has no plans to ban gas stoves.
Oil companies are high on the hog again, with record high gas prices fueling record profits–profits so high they’re even catching the attention of Democrats in Congress. And of course, they’re using the profits to buy back shares so their shareholders will benefit from higher stock prices.
Maybe all that money is going to their heads because only a handful of years have passed since we learned Exxon and many other big oil companies have known since the seventies exactly how their dirty product was about to trigger a global meltdown. Yet they’re still up to their old tricks and trying to fool us while they pump more oil. As governments and communities race to stop runaway climate change, oil companies have quietly found a way to sell even more oil, in the form of plastic. Plastic production is projected to grow astronomically and is expected to account for 60% of oil demand in the next decade.
It would be nice if plastic made from oil was as clean and benign as makers of plastic would like us to believe, but petrochemical plastics are dirty from start to finish, and it’s the product where big oil is placing its largest bets. It turns out some of the biggest oil corporations are also some of the biggest petrochemical corporations. And petrochemical production is mostly plastics.
Cheerleaders of increased plastic production can talk all day about how the solution to the plastic waste crisis is simply more recycling, but less than 9% of plastic is actually recycled, and the industry is now trying to relabel plastic incineration as recycling to help justify increased production. And plastic waste may be just the tip of the iceberg. Before all of the needless plastic products and packaging oil companies make even reach the waste stream, they’ve already done countless damage to communities near sites of production and to consumers.
To make plastic out of oil, petrochemical plants release toxic air pollution that saddles nearby communities with inordinate negative health impacts, communities which are more often likely to be communities of color. If plastic production increases as planned, these communities will be subject to even more dangerous air pollution than they already grapple with.
Once the plastic is made, it enters the market where consumers become the next group of humans put at risk by dirty oil in the form of petrochemical plastic. Unless you live on the dark side of the moon, where presumably it’s not yet a problem, then you’ve probably heard of the microplastics problem. How plastic things fall apart into little pieces, each shred smaller than the last. How scientists can’t seem to find a place on the planet that’s not teeming with microplastics. How scale doesn’t matter because it’s in the air above the tallest mountains, in the streams on every continent, and in our blood and breastmilk. Now that we know it’s everywhere, scientists are beginning to ask if plastic is actually safe, because it’s made with myriad chemicals.
As they examine the toxic impacts of petrochemical plastics, scientists are beginning to warn that it’s not looking good for us. The more research that is done into the impact of plastics on human health, the more that dangers are discovered. Plastic contains many toxic chemicals, and it turns out many of those chemicals are moving from the plastic into our bodies. That plastic soda bottle you drank out of last week? Odds are good that the chemical used as a catalyst in the bottle making process has made its way into the soda. That polyester stuffed animal your infant adorably sucks on the ears of? It’s also made with a dangerous catalyst that may be released into your child’s mouth. Defend Our Health tested beverages in plastic bottles and found dangerous chemicals in every single one, at least one of the chemicals a known carcinogen.
We cannot continue allowing oil companies to poison our air, bodies, and climate with their toxic product. This is a critical moment in history, and when they’re not too busy reaping outrageous profits, oil companies are trying to convince us the product they’re selling isn’t killing the planet and everything on it, despite the evidence. Instead of making more stuff we don’t need, like a box full of air-filled plastic bubbles that take up nine-tenths of the box space because it was somehow cheaper for Amazon to mail a thing that way, perhaps the industry could check the room and start trying in earnest to transition itself off its dirty product. You’d think none of these companies would want to be the last one around trying to sell a product no one wants, but it seems they’re all participating in a mass delusion driven by short-term thinking. It’s time to draw down, not ramp up, oil and gas, and that means plastic production too.
