A Shopper’s Guide to Home Tissue Products
By Patrick Rogers
In the U.S., we consume more than 15 billion pounds of tissue each year—more than 50 pounds per person. It's taking a major toll on forests like the Canadian boreal.
Few people give much thought to how their toilet paper is made. And to be fair, there's nothing particularly engaging in the backstory of this industrially produced, single-use paper product. But it's important to remember that many toilet paper products equal trees—and we flush them down the drain at an alarming rate. Each year, vast swaths of forest are logged to produce the wood pulp that gets turned into toilet paper, with the final product chemically bleached to whiten and soften.
In fact, tissue products—facial tissues, paper towels, napkins, and toilet paper—are the fastest-growing sector of the international paper industry, with production forecast to rise by 6 percent annually through 2022. In the U.S., we consume more than 15 billion pounds of tissue each year. That means we currently buy, use, and flush about 20 percent of the world's supply of tissue products, even though we account for just over 4 percent of the world's population.
To see the devastating impact of this market, U.S. consumers need only look north of the Canadian border to the great boreal forest that rings the continent in green, which is being felled at an alarming rate, in part to satisfy the global appetite for tissue. Logging crews mostly clear-cut 28 million acres of woodland between 1996 and 2015, an area roughly the size of Ohio, according to NRDC's report The Issue With Tissue: How Americans Are Flushing Our Forests Down the Toilet.
This logging destroys and degrades wildlife habitat, threatens the lands and way of life of indigenous peoples, and robs the planet of one of its most important defenses against climate change. "The boreal is a massive storehouse of carbon that has accumulated in its soils and vegetation over millennia," said the report's author, Jennifer Skene, an environmental law fellow in NRDC's International Program. "When it is released because of logging, it has devastating ramifications for global efforts to mitigate climate change."
Only by using alternatives to tissue products made with virgin wood pulp can we begin to reverse the destruction of the Canadian boreal and other forests, Skene said, who points out that "Many people are not aware of the toll tissue takes on our forests." Here's how you can be part of the solution.
Shop for Sustainability
Fortunately, there are plenty of competitively priced varieties of tissue with minimal impact on forests. The Issue With Tissue report's scorecard assigns grades to all the major brands of toilet paper, paper towels and facial tissues, as well as popular house brands at leading supermarkets and brands that have adopted more sustainable practices.
Leading the scoreboard are six products — Green Forest, 365 Everyday Value 100% Recycled, Earth First, Natural Value, Seventh Generation and Trader Joe's Bath Tissue — that are made entirely of recycled material and use a chlorine-free bleaching process that does less harm to the environment than other methods. Grades of A go to toilet papers that contain the most postconsumer recycled content; this means that most of their materials have already been processed once and therefore reduce waste. (The alternative, preconsumer recycled content, is largely scrap and excess raw material collected during the manufacturing process. While it is far preferable to virgin forest fiber, it does less to offset waste than postconsumer recycled content.) The brands that get an A "have looked into the impact of their products and are embracing alternative materials that will allow us to continue using tissue products with a fraction of the environmental cost," Skene said.
Think Twice Before Buying These Products
Brands that get an F in the scorecard — including Charmin Ultra, Angel Soft, Quilted Northern and Up & Up Soft & Strong — rely entirely on virgin forest fiber for their products. These tissue products have three times the carbon footprint of those made from recycled paper; many also use dangerous bleaching processes. You may notice that the label "FSC certified" appears on some of these brands. While the Forest Stewardship Council is the world's most creditable independent certifier of responsibly managed forests and provides an important set of standards for products that require the use of wood (like lumber), there is no reason tissue products should be made from trees in the first place, Skene said.
Give Your Household Tissue Use More Consideration
Next time you reach for a package of facial tissue at the supermarket, visualize a majestic evergreen spruce or fir in the forest. "Something that we use once and throw away should not be destroying a vital part of our earth," said Shelley Vinyard, who oversees NRDC's work encouraging corporations to establish stronger protections for Canada's boreal forest. In the bathroom, use paper tissue products with reusable materials that get the job done. Keep rags beside your sink and use them as much as possible instead of paper towels. Replace paper napkins with cloth versions, and instead of one-and-done facial tissues, rely on handkerchiefs and washcloths that can be laundered and reused indefinitely.
Despite the steady degradation of the boreal forest, the leading tissue brands stubbornly maintain a business-as-usual approach to the manufacture and marketing of paper tissue products. Charmin, Bounty, Kleenex and other brands continue to manufacture tissue using methods that have changed little since the 19th century, still relying entirely on virgin wood pulp. Meanwhile, they have vast research and development budgets that they could leverage to create soft, strong recycled tissue products. "The companies themselves have said people aren't calling for this," said Vinyard. You can help change the manufacturers' minds by letting them know your concerns about wood pulp from Canada's boreal forest—nearly 60 percent of which is shipped to the United States annually.
"It's all about where responsibility lies," said Vinyard. "Consumers can create the demand for recycled content, but really it's up to major companies with large R&D budgets to innovate and figure out how to make a product that is appealing to shoppers and doesn't destroy our forests."

If weather is your mood, climate is your personality. That's an analogy some scientists use to help explain the difference between two words people often get mixed up.
Size Matters<p>Climates are a bit like woven tapestries. The big picture is important, no question. But so are all the seemingly minor details found inside the larger whole.</p><p><a href="https://research-information.bris.ac.uk/en/persons/tommaso-jucker" target="_blank">Tommaso Jucker</a> is an environmental scientist at the University of Bristol. In an email, Jucker says he'd define the term microclimate as "the suite of climatic conditions (temperature, rainfall, humidity, solar radiation) measured in localized areas, typically near the ground and at spatial scales that are directly relevant to ecological processes."</p><p>We'll talk about that last bit in a minute. But first, there's another criteria to discuss. According to some researchers, a microclimate — by definition — must differ from the larger area that surrounds it.</p><p><a href="https://www.cfc.umt.edu/research/paleoecologylab/publications/Davis_et_al_2019_Ecography.pdf" target="_blank">Forests</a> provide us with some great examples. "The climate near the ground in a tropical rainforest is dramatically different from the climate in the canopy 50 meters [164 feet] above," says University of Montana ecologist <a href="https://www.cfc.umt.edu/personnel/details.php?ID=1110" target="_blank">Solomon Dobrowski</a> in an email. "This vertical gradient among other factors allows for the staggering biodiversity we see in the tropics."</p><p>Likewise, scientists observed that a 2015 partial <a href="https://animals.howstuffworks.com/insects/bees-stopped-buzzing-during-2017-solar-eclipse.htm" target="_blank">solar eclipse</a> caused the air temperature of an Eastern European meadow to <a href="https://rmets.onlinelibrary.wiley.com/doi/full/10.1002/wea.2802" target="_blank">change more dramatically</a> than it did in a nearby forest. That's because trees provide not only shade, but their leaves also reflect solar radiation. At the same time, forests tend to reduce wind speeds.</p><p>All those factors add up. A 2019 review of 98 wooded places — spread out across five continents — found that forests are 7.2 degrees Fahrenheit (4 degrees Celsius) <a href="https://natureecoevocommunity.nature.com/posts/47363-forests-protect-animals-and-plants-against-warming" target="_blank">cooler on average</a> than the areas outside them.</p><p>Now if you hate the cold, don't worry; there's a cozy exception to the rule. According to that same study, forests are usually 1.8 degrees Fahrenheit (1 degree Celsius) warmer than the external environment during the wintertime. Pretty cool.</p>
A Bug's Life<p>When does a microclimate stop being, well, micro? In other words, is there a maximum size we should be aware of when discussing them?</p><p>Depends on who you ask. "In terms of horizontal scale, some have defined 'microclimate' as anything that is less than 100 meters [328 feet] in range," Jucker says. "I'm personally less prescriptive about this."</p><p>Instead, he says the "scale at which we want to measure [a particular] microclimate" ought to be "dictated" by the questions we're trying to answer.</p><p>"If I want to know how temperature affects the photosynthesis of a leaf, I should be measuring temperature at centimeter scale," Jucker explains. "If I want to know if and how temperature affects the habitat preference of a large, mobile mammal, it's probably more relevant to capture temperature variation across [tens to hundreds] of meters."</p><p>For instance, solitary plants have the power to generate itty-bitty microclimates. Just ask <a href="https://www.colorado.edu/geography/peter-blanken-0" target="_blank">Peter Blanken</a>, a geography professor at the University of Colorado, Boulder and the co-author of the 2016 book, "<a href="https://amzn.to/2XN6FT8" target="_blank">Microclimate and Local Climate</a>."</p>
The urban heat island effect is a good example of how microclimates work. NOAA
Microclimates on a Grand Scale<p>It's no secret that our planet is going through some rough times at the macro level. The global temperature is <a href="https://climate.nasa.gov/vital-signs/global-temperature/" target="_blank">climbing</a>; nine out of the <a href="https://www.noaa.gov/news/2019-was-2nd-hottest-year-on-record-for-earth-say-noaa-nasa" target="_blank">10 hottest years on record</a> have occurred since 2005. And by one recent estimate, roughly 1 million species around the world are <a href="https://ipbes.net/sites/default/files/2020-02/ipbes_global_assessment_report_summary_for_policymakers_en.pdf" target="_blank">facing extinction</a> due to human activities.</p><p>"One of the big questions that ecologists and environmental scientists are trying to answer right now is how will individual species and whole ecosystems respond to rapid climate change and habitat loss," says Jucker. "...To me, [microclimates are] a key component of this research — if we don't measure and understand climate at the appropriate scale, then predicting how things will change in the future becomes a lot harder."</p><p>Developers have long understood the impact small-scale climates have on our daily lives. <a href="https://science.howstuffworks.com/environmental/green-science/urban-heat-island.htm#pt0" target="_blank">Urban heat islands</a> are cities that have higher temperatures than neighboring rural areas.</p><p>Plants release vapors that can moderate local climates. But in cities, natural greenery is often scarce. To make matters worse, plenty of our roads and buildings have a bad habit of absorbing or re-emitting heat from the sun. <a href="https://www.google.com/books/edition/Microclimate_and_Local_Climate/LHUZDAAAQBAJ?hl=en&gbpv=1&bsq=urban%20heat%20island" target="_blank">Vehicle emissions</a> don't exactly help the situation.</p><p>Still, it's not like Boston or Beijing are thermal monoliths. Sometimes, the documented temperatures <a href="https://e360.yale.edu/features/can-we-turn-down-the-temperature-on-urban-heat-islands" target="_blank">within a single city</a> vary by 15 to 20 degrees Fahrenheit (8.3 to 11.1 degrees Celsius).</p><p>That's where metro parks and city trees come in. They have nice cooling effects on nearby neighborhoods. "Several cities around the world have developed programs to increase urban green spaces," says Blanken. "Tree planting programs and green roof programs, have been shown to lower surface temperatures, decrease air pollution and decrease surface water runoff (urban flash-flooding) in urban areas."</p>

If asked to recall a hurricane, odds are you'd immediately invoke memorable names like Sandy, Katrina or Harvey. You'd probably even remember something specific about the impact of the storm. But if asked to recall a heat wave, a vague recollection that it was hot during your last summer vacation may be about as specific as you can get.

One of the challenges of renewable power is how to store clean energy from the sun, wind and geothermal sources. Now, a new study and advances in nanotechnology have found a method that may relieve the burden on supercapacitor storage. This method turns bricks into batteries, meaning that buildings themselves may one day be used to store and generate power, Science Times reported.
Bricks are a preferred building tool for their durability and resilience against heat and frost since they do not shrink, expand or warp in a way that compromises infrastructure. They are also reusable. What was unknown, until now, is that they can be altered to store electrical energy, according to a new study published in Nature Communications.
The scientists behind the study figured out a way to modify bricks in order to use their iconic red hue, which comes from hematite, an iron oxide, to store enough electricity to power devices, Gizmodo reported. To do that, the researchers filled bricks' pores with a nanofiber made from a conducting plastic that can store an electrical charge.
The first bricks they modified stored enough of a charge to power a small light. They can be charged in just 13 minutes and hold 10,000 charges, but the challenge is getting them to hold a much larger charge, making the technology a distant proposition.
If the capacity can be increased, researchers believe bricks can be used as a cheap alternative to lithium ion batteries — the same batteries used in laptops, phones and tablets.
The first power bricks are only one percent of a lithium-ion battery, but storage capacity can be increased tenfold by adding materials like metal oxides, Julio D'Arcy, a researcher at Washington University in St. Louis, Missouri, who contributed to the paper and was part of the research team, told The Guardian. But only when the storage capacity is scaled up would bricks become commercially viable.
"A solar cell on the roof of your house has to store electricity somewhere and typically we use batteries," D'Arcy told The Guardian. "What we have done is provide a new 'food-for-thought' option, but we're not there yet.
"If [that can happen], this technology is way cheaper than lithium ion batteries," D'Arcy added. "It would be a different world and you would not hear the words 'lithium ion battery' again."
One of the concerns about a warming planet is the feedback loop that will emerge. That is, as the planet warms, it will melt permafrost, which will release trapped carbon and lead to more warming and more melting. Now, a new study has shown that the feedback loop won't only happen in the nether regions of the north and south, but in the tropics as well, according to a new paper in Nature.
