Eliminating plastic shipping pillows

By Leave a Comment

Anyone who gets packages from Amazon is familiar with the plastic air pillows used to keep products safe in transit.  Amazon uses almost 15 billion of them a year in North America.

Environmentalists have been urging Amazon and other vendors to cut down on the use of plastic packaging. The air-filled plastic pillows are made from plastic film, which is the most common form of plastic litter found in the sea and in seabeds along the shore.  Plastic film can be deadly to wildlife such as sea turtles and sea birds.  Plastic film generally can’t be composted or recycled either.

Recently, Amazon announced that it will replace its plastic pillows with recycled paper filler in all its North American markets – the United States, Canada, and Mexico – which together account for more than 70% of the retailer’s global sales.  It is already making the switch in a big way and is working towards fully removing the plastic materials by the end of the year.

Replacing plastic packaging with paper is a definite improvement.  Paper is recyclable and biodegradable.  It isn’t perfect:  if it ends up in landfills, it can contribute to methane pollution as it biodegrades.  But, on the other hand, paper packaging is more likely to be recycled.

Stemming the tide of plastic waste is an ongoing effort by environmental and consumer groups.  There is pending legislation in New York that aims to reduce the use of plastic packaging by 50% over 12 years by requiring manufacturers to either replace it or pay fees.  The bill cleared the State Senate but has not come up to a vote in the Assembly.  Similar legislation has already been passed in California, Oregon, Maine, and Colorado.

A plug for all cars

By Leave a Comment

Different brands of electric cars have required different charging connections. There has been no standard connector for charging.  But now, as the transition to electric vehicles is accelerating, there is the North American Charging Standard, which within in the next couple of years, will be common to pretty much any new electric vehicle on the road.

There have been several different charging connector systems in use by auto manufacturers and each charging station offered only a particular one of them.  The largest charging network in the US has been Tesla’s Supercharger Network, which uses a proprietary standard it put in place in 2012.  Tesla offered to open up their charging technology to other cars but auto manufacturers declined to take them up on the offer for a number of years.  The Bipartisan Infrastructure Law, passed in 2021, provided federal subsidies for building out fast charging networks, provided a common charging standard was adopted.  That has broken the log-jam.

The Tesla Charging Standard has been renamed the North American Charging Standard and Tesla opened its technology to other manufacturers in November 2022.

Automakers who have signed on to the standard include BMW, General Motors, Honda, Hyundai, Jaguar Land Rover, Lucid, Mercedes-Benz, Nissan, Polestar, Rivian, Subaru, Toyota, and Volvo.  In December, the Volkswagen Group – which includes Volkswagen, Porsche, and Audi – announced that they are also implementing it for future vehicles in North America, starting in 2025.   (The only significant holdout is Stellantis, parent of Dodge, Chrysler, and Jeep).

It will be a year or two before cars from all these companies will have the NACS connector and be able to charge at the same stations, but it will happen.

The Spooky Reality | Earth Wise

By Leave a Comment

According to the National Retail Federation, American consumers will spend a whopping $12.2 billion on Halloween this year, exceeding last year’s record of $10.6 billion.  A record number of people – 73% of Americans – will also participate in Halloween-related activities this year, up from 69% in 2022.  But it’s not just our wallets that take a beating. 

Halloween generates a frightening amount of waste.  Picture all those flimsy and often single-use costumes, polyester cobwebs, plastic-wrapped candy, mass-produced decorations, and so forth. Scary stuff!  Here are some simple tricks to make the holiday more sustainable this year. 

Invest in quality costumes.  Those mass-produced costumes leave the largest carbon footprint from Halloween.  They are often made from non-recyclable plastic and most end up in landfills by mid-November.   By renting, thrifting, swapping, or making your own costumes, many of the negative impacts of dressing up for the holiday can be avoided.

Find environmentally-friendly decorations and supplies.  For example, carve local pumpkins and either save the seeds and flesh to eat later, compost it, or feed it to animals.  Make your own spooky decorations.  If you do buy decorations, ensure that they are durable and reusable.  And use wicker baskets, old bags, or pillowcases when trick-or-treating.

Finally, purchase organic and fair trade candy if you’re able to do so.  Some of the largest candy manufacturers are major drivers of deforestation and species extinction around the globe due to their demand for sugar, palm oil, and cocoa beans.

Together, we can “green” Halloween.

Banning Neonicotinoid Pesticides | Earth Wise

By Leave a Comment

New York’s Birds and Bees Protection Act contains a targeted restriction on neonicotinoid pesticides. These widely-used insecticides are absorbed by plants and can be present in pollen and nectar, making them toxic to bees and other pollinators.

Among the largest applications of neonics (as they are called) has been in the form of coatings on crop seeds, such as corn and soybeans.  In 2019, Canada’s Quebec province strongly limited neonic use to protect pollinators and the environment.  The chemical industry vigorously protested the regulations and claimed that the restrictions would cause the collapse of the grain sector in Quebec.

Seed suppliers began supplying uncoated seeds in 2019 and now there is scarcely any use of coated seeds in the province.  Monitoring of over 1,000 agricultural sites has shown that there have been no crop failures related to the pesticide restrictions.  In fact, use of the neonics had no economic benefits. 

Naysayers warned that even more harmful pesticides or other farming practices would be used instead.  But that hasn’t happened either. Some farmers switched to much safer insecticides and others abandoned insecticide treatments altogether.

New York has faced similar opposition by farmers and chemical manufacturers to the Birds and Bees Protection Act and all of the same arguments that have been proven to be invalid in Quebec are being made in New York.  Most major environmental advocates in the state support the measures embodied in the legislation.  As usual, it boils down to a battle between economic interests and the health of the environment.

Pollution From Tires | Earth Wise

By Leave a Comment

A few years ago, researchers investigating massive deaths of coho salmon in West Coast streams discovered that the water contained particles from vehicle tires.  The cause of the fish mortality turned out to be a chemical called 6PPD that is added to tires to prevent cracking and degradation.  The mystery was solved, but so far, the chemical continues to be used by all major tire manufacturers and is found on roads and in waterways around the world.

Worse still, the acute toxicity of 6PPD and the chemicals that it transforms into when exposed to ground-level ozone is only the tip of the tire pollution iceberg.  Tire rubber contains more than 400 chemicals and compounds, many of which are carcinogenic. 

About 2 billion tires are sold across the globe each year and that number is expected to reach 3.4 billion by 2030.  Tires are made from about 20% natural rubber and 24% synthetic rubber, which requires about 4 gallons of petroleum per tire.  Hundreds of other ingredients – including steel, fillers, heavy metals like copper, cadmium, lead, and zinc – make up the rest.

Tire wear particles are emitted continually as vehicles travel.  They range in size from visible pieces of rubber or plastic to microparticles.  Research has shown that a car’s four tires collectively emit half a trillion ultrafine particles per mile driven.  These particles are small enough to be breathed into the lungs and can travel throughout the body and even cross the blood-brain barrier.  Particle pollution from tires exceeds that from tailpipes.

Tire pollution is a huge problem that is just starting to receive the attention it deserves.

Electric Vehicle Tax Credits | Earth Wise

By Leave a Comment

As of January 1, many Americans can qualify for a tax credit of up to $7,500 for buying an electric vehicle.  The credit is one of the changes enacted under last year’s Inflation Reduction Act.  The purpose is to encourage EV sales and thereby reduce greenhouse gas emissions and air pollution.

There has been a tax credit for EVs for more than a decade, but its provisions made cars from any manufacturer ineligible as soon as that manufacturer had sold more than 200,000 cars.  Notably, this eliminated the credit for purchasing cars from Tesla and General Motors.  Given that electric cars are now selling in the millions, the 200,000-unit cap on the tax credit essentially made it useless as a real force to grow the industry.

The new tax credit has a somewhat complex set of requirements for determining the applicability and amount of the credit.  There are price limits on eligible vehicles depending on vehicle type and there are requirements on where vehicles are manufactured, where batteries are manufactured, and where other components are made. The intent is to encourage American manufacturing of the cars and trucks to the greatest extent.  There are also income limitations on buyers who want to take advantage of the credit, but those are quite large.  The Department of the Treasury has online detailed information about the requirements for the credit and, of course, EV manufacturers can provide the specifics for their own vehicles.

For their part, automakers are adjusting prices, building domestic manufacturing plants and battery factories, and otherwise trying to position themselves for their customers to take advantage of the credit.

The new law also provides a smaller tax credit for the purchase of used electric vehicles.

The Race For American Lithium Mining | Earth Wise

By Leave a Comment

The auto industry is making a massive transition from gas-powered cars to electric cars.  The exploding electric vehicle market has set off what some call a global battery arms race.  Battery manufacturers are urgently trying to source the raw materials needed to make batteries, which presently include cobalt, nickel, graphite, and lithium.  There is encouraging progress in reducing and even eliminating cobalt and nickel from electric car batteries, but so far lithium seems to be essential.

The International Energy Agency has named lithium as the mineral for which there is the fastest growing demand in the world.  Estimates are that if the world is to meet the global climate targets set by the Paris Agreement, at least 40 times more lithium will be needed in 2040 compared with today.

According to the US Geological Survey, the US has about 9 million tons of lithium, which puts it in the top 5 most lithium-rich countries in the world.  Despite this, our country mines and processes only 1% of global lithium output.  Most of the rest comes from China, Chile, and Australia.  Being dependent upon these foreign sources is a serious concern for national security.

There is only one operational lithium mine in the US at present.  Multiple companies are pressing to get more mining projects in operation, including sites in North Carolina and Nevada.  But there are serious environmental problems associated with lithium mining and there is considerable local opposition to establishing the mines.

The US wants to be a leader in the global race to build the batteries that will power the green transition but it is a complicated situation that combines both undeniably important benefits as well as very real dangers.

Cheaper Electric Cars | Earth Wise

By 1 Comment

The price of the batteries that power electric cars has fallen by about 90% since 2010.  This continuing trend will eventually make EVs less expensive than gas cars.

For many years, researchers have estimated that when battery packs reach the price of $100 per kilowatt-hour of energy storage, electric cars will cost about the same as gasoline-powered vehicles.  In 2021, the average price of lithium-ion battery packs fell to $132 per kilowatt-hour, down 6% from the previous year.  According to analysts, batteries should hit the average of $100 as soon as 2024.

It is not the case that as soon as the $100 level is reached, EVs will abruptly reach cost parity.  Across different manufacturers and vehicle types, the price shift will occur at different rates.  However, by the time batteries reach $60 a kilowatt-hour, EVs will be cheaper than equivalent gasoline models across every vehicle segment.

It is not known exactly when EVs will cost less than gasoline models, but there is little doubt that this point is coming.  We have only been talking about the purchase price of a new vehicle.  When one looks at the total cost of ownership of a vehicle, including fuel, insurance, maintenance, and depreciation, it is a different story.

Because of savings on fuel and maintenance, EVs are already in many if not most cases cheaper to own than gas-powered cars.  The Department of Energy provides an online calculator to help consumers estimate the cost differences between gasoline and electricity.

In any case, the number of electric cars on the market is increasing and the number of gas-powered cars will be shrinking.  Sooner or later, we will all drive electric.

Is Peak Oil Here? | Earth Wise

By Leave a Comment

For many years there has been talk of “peak oil”, the point at which rising world oil consumption would peak and then start declining.  Some analysts have been predicting that this could happen by the 2030s.   But the coronavirus pandemic drove a 9% slump in oil demand in 2020 that some economists are saying might never be entirely reversed.

There are three major forces driving down the world’s appetite for oil:  decarbonization of economies to meet the goals of the Paris climate agreement, declining demand for oil as renewable energy sources and electric vehicles are increasingly adopted, and detoxification as cities act to curb particulates and emissions from burning petroleum.

The largest single factor is electric vehicles.  Automobiles currently consume almost half of the world’s oil.  As of the end of 2020, there were an estimated 10 million electric cars as well as more than 600,000 electric buses and trucks.  This is still less than 1% of all vehicles, but 5% of all new cars being bought are now electric and the number is growing rapidly.  Experts estimate that nearly a quarter of global car sales will be electric vehicles by 2025 and many car manufacturers are promising to sell only electric cars within the next 10 years.

The decline in oil demand is pretty much inevitable at this point.  The main question is how quickly it will happen.  Road transport makes up 48% of global oil demand, petrochemicals account for 14%, aviation 7%, and shipping 6%.  Ultimately all these things are likely to diminish over time. 

Only time will tell, but the long-awaited arrival of peak oil may already have happened.

Have We Reached Peak Internal Combustion Engine? | Earth Wise

By 1 Comment

According to new analysis from Bloomberg New Energy Finance, global sales of gas-powered cars may well have peaked in 2017, representing a significant milestone in the transition to electric vehicles.

Demand for gas cars dropped in 2018 and 2019, and then plummeted in 2020 as a result of the coronavirus pandemic.  While sales are surely picking up as the pandemic ebbs, the increasing demand (and supply as well) for plug-in vehicles is likely to put gas-powered cars in a state of permanent decline.

Global EV sales are projected to go from 3.1 million last year to 14 million in 2025.  The growth is being driven by falling battery prices, government policies, and increasing choices of vehicles.  Virtually all automobile manufacturers are introducing electric vehicles over the next couple of years and increasing numbers of them are planning a complete transition to EVs in the near future.  Projections are that EVs will account for the majority of new car sales by 2035.

While all this progress is encouraging, there are still over a billion gas- and diesel-powered cars on the road and the fleet turns over slowly.  The current average operating life of cars here in the US is 12 years.

To reach the net-zero carbon emission goals by 2050 as many governments have mandated, additional policies and regulations will be needed.  For example, electric cars will need to account for essentially all new sales by 2035, not just the majority.  Reaching net-zero by mid-century will require all hands on deck, including trucks and heavy commercial vehicles that have barely started to become electrified.

An Incentive For Carbon Capture | Earth Wise

By Leave a Comment

Convincing industries to reduce their carbon dioxide emissions has not been easy.  Many approaches have been debated, including carbon taxes, carbon tax-and-trade schemes, and passing a giant Green New Deal.  Most economists agree that putting a price on carbon is likely to be the most effective approach.

But there is already in place an adjustment to the US tax code that is more of a carrot than a stick.  It is a tax credit that is designed to make capturing CO2 a financial winner for a number of high-emitting industries.  The credit, called 45Q, was enacted in February 2018.

The 45Q credit earns industrial manufacturers $50 per metric ton of CO2 stored permanently or $35 per ton if the CO2 is put to use.  An earlier credit for capturing carbon dioxide was limited to only $20 per metric ton and was capped at 75 million tons.  Some large fossil fuel companies did make use of the earlier credit.

The new version does not have a cap, but to qualify, companies need to start constructing carbon-capture facilities within 7 years and have 12 years to claim their money.

Companies with emission-intensive operations are busy figuring out how to take advantage of the credit.  These include cement makers, steel and power plants, corn ethanol producers, and ammonia plants.

Because the credit mandates that companies start constructing their carbon-capture facilities within seven years, most companies will tend to rely on mature technologies.  But the tax credit should also drive demand for next-generation carbon-capture technologies, of which there are many under development.  Saving lots of money on taxes is likely to lure US companies to capture carbon dioxide.

Supermarkets And Zero-Waste

By Leave a Comment

There are about 38,000 supermarkets in the United States alone and they are responsible for vast quantities of waste in the form of single-use plastic bags, plastic containers that store food products, and food waste as well.  Globally, over 80% of poll respondents feel strongly that companies should help improve the environment.  Responding to this message, markets are starting to make changes.

In a number of places, there are now markets that are package-free.  The Nada grocery store in Vancouver and Precycle in Brooklyn are examples of zero waste grocery stores.  Websites like Litterless provide online help for customers trying to find packaging-free grocery stores.

Markets are not only changing their packaging, they are using artificial intelligence to develop more sustainable production processes and seeking other ways to reduce waste.

On average, Americans throw away over 300 plastic bags a year, but an increasing number of grocery retailers are making commitments to more sustainable, plastic-free options.  It isn’t just small stores either.  Grocery giant Kroger plans to eliminate plastic bags in its stores by 2025.  When that happens, it means that 6 billion plastic bags will no longer be distributed.  Big Y stores will fully transition to reusable bags by next year.  More and more cities and states are banning or imposing fees on plastic bags. 

An interesting statistic shows that the age group of Americans that is leading the adoption of reusable grocery bags is not millennials but in fact is people over 50.  With multiple generations now indicating that they want shopping to be more sustainable, it is likely that supermarkets will strive to help make that happen.

China And Plastic Waste

By Leave a Comment

In January 2018, China enacted its “National Sword” policy which banned the import of most plastics and other materials headed for that country’s recycling processors.  Those processors had handled nearly half of the world’s recyclable waste for the past quarter century.  China took this step because the deluge of soiled and contaminated materials was overwhelming its processing facilities and creating yet another environmental problem for the country, this time not even of its own making.

Prior to China’s ban, 95% of the plastics collected for recycling in the European Union and 70% in the U.S. were sold and shipped to Chinese processors.  A combination of favorable rates for shipping in cargo vessels that carried Chinese goods abroad and low Chinese labor rates made it a very profitable enterprise.

Before China’s ban, only 9% of globally discarded plastics were being recycled and 12% were burned.  The rest ended up in landfills or simply dumped into the environment.  Over the coming decade, as many as 11 million tons of plastic will have to find a new place to be processed or otherwise disposed of.  There is already evidence that plastic waste is accumulating in countries that are dependent on exporting.  In many places, including a number of American cities, there are curtailed collections and new restrictions on what kinds of plastics are accepted.

Some experts are hopeful that China’s ban might actually have an upside if it leads to better solutions for managing the world’s waste.  North America and Europe need to expand processing capabilities and manufacturers need to make their products more easily recyclable.  Mostly, the Chinese ban should be a wake-up call to the world on the need to greatly reduce single-use plastics.

The Threat From Nurdles

By Leave a Comment

Just when we thought we knew all about the environmental threats caused by plastics, environmentalists have identified yet another problem.  It is called a nurdle.

Nurdles are tiny pellets of plastic resin no bigger than a pencil eraser that manufacturers transform into packaging, plastic straws, water bottles and all the other things that are wreaking havoc on the environment.

It turns out that nurdles themselves are a problem because billions of them are lost from production and supply chains during handling, shipping and production every year, spilling or washing into waterways.  There is limited information on the extent of this kind of plastic pollution and global researchers are still struggling to make an accurate assessment.  A study last year estimated that 3 million to 36 million pellets escape every year from just one small industrial area in Sweden.

Eunomia, a British environmental consultancy, contends that nurdles are the second-largest source of microplastic pollution and estimated that the U.K. could be unwittingly losing billions of pellets into the environment every year.

New research is revealing the ubiquity of plastic pellets, from the bellies of fish caught in the South Pacific, to the digestive tracks of short-tailed albatross in the north and on the beaches of the Mediterranean.

A shareholder advocacy group called As You Sow has filed resolutions with Chevron, DowDupont, Exxon Mobil, and Phillips 66 asking them to disclose how many nurdles escape their production process each year and how they plan to address the issue.  Several of the companies have responded with statements saying they are working to develop solutions that keep plastic out of our environment.

The Problem Of Microplastics

By Leave a Comment

In recent years, there have been multiple reports of microplastic contamination seemingly everywhere:  in the ocean, in lakes and rivers, in beverages and foods, and in the bodies of birds, fish, and even people.  As the world tries to come to grips with this growing problem, there are many things that we simply don’t know.

Microplastics are usually formed by the breakdown of larger pieces of plastic.  Shopping bags and cups degrade into microplastics.  Microfiber clothing generates microplastics in washing machines.  And some manufacturers still intentionally add microplastics to personal care products like toothpaste and facial scrubs.

Technically, a microplastic is any piece of plastic measuring five millimeters in size down to one micron – which is one thousandth of a millimeter.  But there can be even smaller plastic particles classified as sub-microplastics and even nanoplastics.

A real concern is that it is not actually clear how dangerous microplastics are for living organisms.  We know that aquatic and terrestrial species – including humans – can and do absorb microplastic particles, but whether there is actual toxicity and the nature of any detrimental effects is not yet well understood.

Another real problem is that it is actually not easy to distinguish microplastics from other particles in a given sample.   When you are looking at a particle that is smaller than a millimeter in size, it is not easy to tell whether it is a grain of sand, a bit of cellulose from a plant, or a microplastic.  There are reliable and definitive ways to analyze samples for microplastics, but they are not as simple and commonplace as just looking through a microscope.

Microplastics are a rapidly growing problem and we don’t even really know how big and how bad the problem is.

Misconceptions About Electric Cars

By Leave a Comment

Tesla’s Model 3 was one of the best-selling cars in the United States last year, eclipsing all but a handful of sedans.  This was the first time that an electric car had that honor and is indicative of how electric cars are finally becoming mainstream.  A host of other new electric models from multiple manufacturers will be the entering the market over the next couple of years.

Despite all of this progress, there is still a great deal of misinformation about electric cars.  A new study commissioned by Volkswagen revealed some of the widespread misconceptions about the vehicles.

Some people believe that electric cars can’t be driven through puddles.  Nearly one in five people believe that electric cars slow down as the battery depletes.  Many people believe that electric cars are fundamentally less safe than gas-powered cars.

More generally, people are unaware of how far current electric cars can drive on a charge.  More and more models can go 200 and even over 300 miles between charging sessions.  People also don’t know how quickly cars can charge up either.  Fast chargers like Tesla’s Superchargers can add 200 miles worth of charge in about 20 minutes.  And people don’t know what it costs to charge electric cars.  In most places, it is only a fraction of what it costs to drive the same distance using gasoline.

Despite their limited knowledge about electric cars, the 2,000 people surveyed in Britain were positively disposed towards them with nearly 6 in 10 saying that they would like to own an electric car some day and would even consider one as their next vehicle.

Electric cars will become more familiar and less exotic as more and more of them are on our roads and highways.
