Water footprint: high, it takes 8,856 liters of water to produce 1 kilogram of green tea / 1,061 gallons of water to produce 1 pound of green tea

Carbon footprint: low, 1.9 kg CO2e to produce 1 kilogram or 2.2 pounds of tea, a car driving equivalent of 4.5 miles or 7.25 kilometers

Destruction: low, green tea production is relatively sustainable, there is no known significant damage to air, water, land, soil, forests, etc. as long as pesticides have not been used, be sure to buy Non-GMO/organic, as toxic, chemical pesticides contaminate air, water, soil, etc., tea plantations have long been considered environmentally friendly, some tea varieties yield suitable leaves for 30 to 100 years, which reduces the need for replanting and any emissions associated with crop planting, most high-quality teas are hand-plucked opposed to machine usage

Green tea isā€¦


Kills: none, green tea production does not require any animals to be killed

Harms: none, green tea production does not require any animals to be used

Indirectly kills or harms: none, no animals are indirectly killed or harmed from green tea production as long as toxic chemicals have not been used, be sure to buy Non-GMO/organic, as pesticides harm and kill wildlife and ecosystems by contaminating soil, water, air and plants that animals eat

Green tea isā€¦


Health and safety: hazardous, limited access to clean water, lack of sanitation, which create health risks, may lead to disease, many workers and their children are malnourished, low immunity to diseases, dangerous exposure to pesticides leads to loss of appetite, numbness in hands, breathing difficulties, reports of starvation deaths

Living conditions: poor, in India, Kenya, Rwanda, Bangladesh, most workers live on tea plantations in decrepit homes, no working toilets, minimal electricity, child trafficking occurs as a result of low wages, children then become slaves, child labor to help meet worker quotas, oppressive conditions intensified by caste system

Wages: low, men work non-leaf-plucking tasks and earn a nearly double hourly wage compared to women, tea pluckers must look for additional work elsewhere to supplement their incomes

Yes! Green tea is high in antioxidants, polyphenols and Vitamin K.

green tea is alkaline.

acidic foods and alkaline diet benefits that improve ph levels

Is green tea alkaline or acidic?

Green tea is alkaline.

What is the pH level of green tea?

Green tea has a 9.0 pH level once digested.

When you eat food, it breaks down to an ash residue that can be neutral, acidic or alkaline. Minerals such as potassium, calcium, magnesium, sodium, zinc, silver, copper and iron produce an alkaline ash; whereas sulfur, phosphorus, chlorine and iodine, which are in meat, coffee, dairy and alcohol, leave an acid ash.

green tea is gluten free.

glutinous foods have side effects but a gluten free diet can help

Is green tea gluten free?

Yes, green tea is gluten free. Green tea does not contain gluten.

While celiac disease may not be as rampant as many marketing trends lead us to believe, you may have a gluten sensitivityā€¦

Is green tea a common food allergen?

No, green tea is not a common food allergen. Some people may experience allergic reactions to green tea but it is relatively rare by comparison.

A group of the eight major allergenic foods, AKA the Big-8, include:

Severe food allergies can be life threatening. Following ingestion of a food allergen, a person with food allergies can experience a severe, life-threatening allergic reaction called anaphylaxis. 

Persons may still be allergic to and have serious reactions to foods other than the eight foods identified by the law.

green tea has a high water footprint.

water footprints of food and products

Does green tea have a high or low water footprint?

Green tea has a relatively high water footprint compared to other foods.

What is the water footprint of green tea?

It takes 8,856 liters of water to produce 1 kilogram of green tea / 1,061 gallons of water to produce 1 pound of green tea.

Did you know that water is a finite, non-renewable resource?

How much water does it take to produce an apple? A serving of rice? A steak dinner?

We need to be aware of something referred to as a ā€œwater footprintā€. That is, the amount of fresh water utilized in the production or supply of goods we consume. As it turns out it takes significantly more water to yield foods that come from animals than foods that come from plants. Imagine how much water a cow needs to consume to generate a piece of beef. Not only how much water a single cow drinks, rather all the water that went into producing the crops that the cow ate.

green tea has a low carbon footprint.

carbon footprints of food and food emissions

Does green tea have a high or low carbon footprint?

Green tea has a relatively low carbon footprint compared to other foods.

What is the carbon footprint of green tea?

It takes around 1.9 kg CO2e to produce 1 kilogram or 2.2 pounds of tea, a car driving equivalent of 4.5 miles or 7.25 kilometers.

Food not only has a water footprint but also a carbon footprint, known as CO2e, which stands for carbon dioxide equivalent. Since carbon measurements are a bit more difficult to comprehend, it is common to equate CO2e to the distance which a car drives in miles or kilometers.

When calculating carbon emissions, some factors may includeā€¦

But thatā€™s not all!

green tea is moderately sustainable.

sustainable shopping, for eco friendly brands and products good for the environment

Overall, is green tea eco friendly? Is green tea sustainable?

Green tea production is moderately sustainable.

Be sure to buy non GMO/organic, as toxic, chemical pesticides contaminate air, water, soil, etc. when using regenerative practices.

A 2018 Oxford University study ā€“ which is the most comprehensive analysis to date of the damage farming does to the planet ā€“ found that ā€˜avoiding meat and dairy is the single biggest way to reduce your impact on Earthā€™ as animal farming provides just 18% of calories but takes up 83% of our farmland.

Consuming animal products and byproducts is not environmentally friendly and is one of the worst things for the Earth. Not only is meat production wasteful, it causes enormous amounts ofĀ pollution. The industry is one of the biggest causes ofĀ climate change.

green tea is vegan.

benefits of vegan food to eat on a vegan diet which helps save animals

Is green tea vegan?

Yes, green tea is vegan. Green tea is made from tea leaves and not an animal product or byproduct, therefore making it a vegan food.Ā 

Animals of factory farming are suffering. They live in horrific conditions that often include confinement, physical abuse and unnatural environmentsā€¦so much so that they need to receive antibiotics to keep from getting ill or spreading disease. Growth hormones allow all kinds of animals to become fatter faster and live short lives.

Because we cannot see for ourselves how these animals live and what they endure does not mean it isnā€™t happening. The meat, poultry and dairy industries do everything they can to distance us from knowing how our food comes to be in order to keep us in the dark about what we support each time we buy animal derived products and byproducts.

Go vegan for animals!

Itā€™s the best way to help animals and itā€™s not as difficult as you may think. Speak for animals with your actions, for they cannot speak at all.

green tea has labor issues and human rights concerns.

benefits of buying fair trade, labor rights, human rights and workers rights issues

Is green tea a product with laborer concerns?

At this time there are concerns with tea production.

Itā€™s important to stay aware of human rights concerns and worker exploitation that may come with specific brands.

Did you know the single largest employer in the world is agriculture? The labor involved behind each and every product cannot go unrecognized. 

Some known problems include workplace health and safety, child labor, gender inequality, inadequate pay, wage theft and exploitation. Workers can even experience harassment, humiliation and violence and unfair employers often fail to provide laborers with access to shade, drinking water, restrooms and breaks. Consequently, laborers can face nausea, dizziness, heat exhaustion, dehydration and heat stroke -the leading cause of farmworker death!Ā 

Such mistreatment is like modern day slavery. Workers are often afraid to report issues because they fear it will result in losing their jobs or deportation. 

Fair trade organizations fight to ensure better social, environmental and economic standards. 

We can improve peopleā€™s lives with foods we eat every day simply by buying products that are certified fair trade.
