Companies Promise Climate Action | Earth Wise

March 30, 2020 By EarthWise Leave a Comment

Companies scramble to achieve climate promises

A growing number of major corporations are making promises on climate and the promises are getting more ambitious and for faster action.  More companies are disclosing their carbon emissions and more of those companies have emissions reduction targets. 

There has also been an acceleration in the rate at which companies set so-called science-based targets, which are specific, measurable carbon reduction goals that align the company with the Paris Agreement.  Among the hundreds of companies with such targets are Coca-Cola, Nike, Best Buy, Walmart, and Hilton Hotels.  According to one analysis, the number of Fortune 500 companies with concrete, ambitious carbon targets quadrupled in the past four year to 23%.

Environmental advocates have been pressuring companies for decades, but companies seem to be far more proactive now despite the fact that the U.S. government has largely dropped the ball on climate issues.

The reasons include the fact that the effects of climate change are becoming clearer to companies.  Wildfires, rising sea levels, droughts and other aspects of the crisis both make headlines and affect business operations.

Meanwhile, solar and wind energy have gotten significantly cheaper, making it more attractive for companies to shift away from fossil fuels.

At the same time, investors are increasingly asking companies to act on climate issues.  Consumers, employees, and the general public are increasingly demanding action and even children are adding to the pressure to act.

Making these commitments is one thing; following through on them and sticking to them is another.  There are real concerns that there is a great deal of green-washing going on among companies trying to project a favorable image.  In any case, if companies really want to lead on climate, they need to put their money where their mouths are.

Packing With Banana Leaves

July 25, 2019 By EarthWise Leave a Comment

More and more places are instituting bans on single-use plastic bags.  Places like California and Hawaii already have bans in place and New Jersey is considering such a ban.  New York’s law will go into effect next March.  Supermarkets will no longer provide plastic bags at the checkout line.  But the laws have some exceptions, including the plastic bags used to hold produce and to pack up meats.

Banning or reducing single-use plastic bags is a growing trend in Asia as well including places like South Korea, Vietnam and Thailand.

One supermarket in Thailand came up with a novel approach to eco-friendly packaging:  wrapping produce in banana leaves.  The idea quickly became a viral hit on social media and drew the attention of supermarkets in Vietnam.  Several big supermarket chains in that country also began experimenting with banana leaves as a packaging alternative.

Representatives of Vietnam’s Lotte Mart chain said that the banana leaf packaging was still in the testing phase, but they plan to replace plastic with leaves nationwide very soon.  Aside from wrapping vegetables and fruits, the grocery chain intends to also use the leaves for fresh meat products.

Customers seem to be quite positive about the new packaging noting that it is actually quite attractive visually.  The banana leaf packaging also makes people more aware of the need for protecting the environment.

While Vietnam is a relatively small country, it turns out that it ranks number four in the world for the largest amount of plastic waste dumped into the ocean.  The country disposes of about 2,500 tons of plastic waste per day. So, efforts like the banana leaf packaging are not just symbolically important, they are genuinely a major environmental imperative.

Powering Cars With Cactus Juice

June 24, 2019 By EarthWise Leave a Comment

Back in 2016, a company called Nopalimex, located in Micoacan, central Mexico, built the world’s first cactus-powered energy plant.  The facility utilizes a biodigester to make biogas from nopal, also known as prickly pear cactus.  The nopal plant has been called the ‘Green Gold of Mexico’ and is a staple in Mexican diets, medicine and cosmetics.

Nopalimex is now using the cactus to make biofuel for vehicles.

The fruit of the cactus is pureed, mixed with manure, and then left to decompose, producing methane.  The methane produced – about eight tons a day – fuels the biodigester which powers the company’s corn chip and cactus chip production and is being tested in a fleet of government vehicles.

The biogas will cost just 65 cents per liter, which is about a third cheaper than the cost of regular gasoline.  Using prickly pear as a feedstock for biofuel is attractive because it can be grown in places where traditional energy crops cannot.  One can imagine vast fields of cacti in remote, arid areas of the country where normal crops cannot grow.  It would not suck up the resources or space needed to feed people, which is an ongoing criticism of current bioenergy crops.

As long as the nopals are regularly replanted, the process is almost entirely sustainable, producing only water and nopal waste, which can be used to fertilize other crops.

Finding sustainable ways to produce fuel while doing minimal damage to the environment is an important challenge for countries around the world.  In Mexico, harnessing the power of the prickly pear cactus is a unique and clever solution.

The ocean energy sector is still at an early stage of development.  Despite the fact that the ocean is permanently in motion, extracting energy from that motion on a major scale continues to be a challenge.  But the potential benefits of ocean technologies are compelling enough that many approaches continue to be pursued.

Natural Mosquito Repellents

With summer comes mosquitoes and our desire to keep them away from us.  The most common repellents are based on the chemical DEET, which unfortunately has been found to have several health and safety problems.   Up to 15% of DEET is absorbed through the skin directly into the bloodstream.  Diethyl-meta-toluamide, the chemical name for DEET, has been shown to have a variety of toxic effects.  Fortunately, it turns out that there are some natural alternatives which may be as effective as DEET, or possibly even more effective than DEET in keeping mosquitoes away from us.
