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.

Diesel Is Dirty

By Leave a Comment

Three years ago, Volkswagen was found to have illegally cheated federal emissions tests in the US using devious programming of emission control devices.  The subterfuge enabled 11 million passenger cars to meet U.S. emissions standards in the laboratory despite that fact that they actually produced up to 40 times higher emissions than the legal limit in real-world driving.

Neonics And Honey

By Leave a Comment

The use of neonicotinoid pesticides or neonics has long been suspected as harmful to bees and a major factor in the widespread decline of honeybee and wild bee populations.  A study published in Science last June provided strong evidence that neonics are indeed a real problem for bees.

Doing More Harm Than Good

A group of more than 200 scientists and medical professionals has issued a consensus statement in the journal Environmental Health Perspectives urging that antimicrobial chemicals like triclosan and triclocarban should not be used in consumer products.  The experts say that these substances offer no health benefits and are actually causing health and environmental harm.

Reducing Food Waste

By

We have talked about food waste before.  It is a big problem in this country:  some 31% of our food supply is wasted, more than 130 billion pounds a year.  Food waste makes up 21% of solid waste in municipal landfills, which means that it accounts for the bulk of landfill methane emissions.  Methane is more than 20 times more effective as a greenhouse gas than carbon dioxide, and landfills are a major source of it.
