Nike Air Force 1 2017 Collection Jade | All Eco Trainers Do Is Kill The Planet a Little Bit Slower [Study]

The threat from climate change YOTD nike Air Jordan 1 Retro High OG Womens Sz UK6 EU40 Atmosphere Pink Navy Trainers.

Recently a number of sustainable trainers have entered the market.

But does anyone actually know what environmental impact their trainers have?

It turns out that if the sneaker industry was a country, it would be the 17th largest polluter each year.

That raises one question in particular: how much do these 'eco-trainers' actually reduce carbon emissions by?

Well, not as much as you might hope.

Eco-trainers are not Air Jordan YOTD nike AJ III 3 Retro SE Quai 54.

In fact, all they’ll do is kill it a little more slowly than conventional trainers.

The average eco-sneaker cuts emissions by less than 10%. Meanwhile, only 1 in every 29 pairs of trainers on the market qualifies as an eco-trainers.

Even worse: on average brands charge an additional $48.79 for a pair of eco trainers -- essentially profiteering from consumers' desires to save the planet, or incentivizing consumers to buy conventional trainers with even higher carbon emissions.

Environmental Impact of a Conventional Pair of Trainers

Before getting into the weeds, it’s to understand how conventional trainers are made and their environmental impact. This way, there is a baseline.

Carbon emissions over the life cycle of a pair of trainers

When a group of researchers at MIT performed a life-cycle assessment (LCA) of a standard pair of trainers, they found a typical pair of running shoes generates 14 kg (30 lbs) of carbon emissions.

The stages of that lifecycle are:

Material Processing - Raw materials being farmed (natural materials) and materials being created (synthetics) to the point where they’re ready to be used in the manufacturing process. The main emissions from the energy associated with processing synthetic materials so they’re ready to be used in the manufacturing stage.

Manufacturing - Taking the processed materials and turning them into the final product. Includes processes such as cutting and stitching the upper, pressing the midsole and outsole, and injection moulding. The main emissions come from the energy used in factories (often in China or Vietnam) that produce the shoes.

Logistics - Transporting raw materials to factories, transporting finished goods to markets where they are sold. Emissions come from fuel used to transport the finished product from the factories in Asia to western countries where they’re sold.

Usage and End of Life - Includes any energy that is used during the life of the trainers. The end of life includes disposal of the shoes and the impact that has on the environment. When in use, the only real emissions are when the trainers are washed. At end of life, the majority of trainers (more than 85%) are sent to landfill or incinerated -- releasing harmful chemicals.

The anatomy of a pair of trainers

On average, trainers have around 65 distinct parts. But, there are 4 or 5 major parts that make up every sneaker.

Materials in Trainers

Polyurethane and Polyester are responsible for the majority of the carbon footprint. Nylon also has a disproportionate impact. They have such a large impact on the carbon footprint because of the amount of energy required to process the materials.

The green alternative is using recycled materials. Recycled polyester uses up to 84% less energy to produce than virgin polyester.

The upper is made up of Nylon, Polyester, and Polyurethane, so it’s responsible for the largest chunk of the carbon footprint.

Looking at the emissions associated with materials, it makes sense to source alternative, more eco-friendly materials for the upper and the midsole.

Summary of Environmental Impact

By looking at the carbon footprint, it is clear that the first two stages (materials processing and manufacturing) make up 92.8% of the carbon footprint.

By itself, the manufacturing stage contributes 64% of the carbon emissions.

Without updating manufacturing processes, major companies are not going to make meaningful strides in reducing carbon emissions -- regardless of what material the sneaker is made from.

Eco-Friendly Trainers

From the MIT study, there is an established baseline of 14 kg of carbon emissions for the lifetime of a conventional pair of trainers, and an understanding where the emissions come from.

From this, an analysis of eco-trainers can take place to determine their credentials as sustainable products.

EdiconnectShops has one of the largest databases of trainers around -- with 2,556 shoes from 34 brands. 89 of those are classified as ‘eco-friendly.’

That’s only 3.4%. Or, 1 of every 29 pairs of trainers.

Of the 89 trainers, more than 95% include recycled plastic.

For example, the Adidas NMD_CS1 Parley Primeknit. Up to 95% of the Primeknit in the shoe’s upper is made from plastic bags salvaged from the ocean in partnership with Parley for the Oceans.

The same story the YOTD nike Free RN Flyknit MS. They incorporate YOTD nike’s own polyester knit material into their design. It’s made from plastic bottles diverted from landfill and that are recycled into polyester thread.

Brooks manufacture running shoes with a biodegradable midsole to lessen the end of life impact of their shoes.

Let’s look at the numbers with some specific examples.

Adidas Ultra Boost Parley

The Adidas Ultra Boost Parley is made using plastic bottles (around 11 per shoe) retrieved from the ocean. These are turned into Primeknit material. Adidas claims 95% Draymond Green Rocks the YOTD nike Zoom Flight 98 "The Glove" against Clippers is made from recycled plastic bottles.

It is possible to calculate the carbon footprint of these trainers by using knowledge gathered from the MIT study covering conventional trainers.

The upper makes up 41% of emissions in the materials processing stage.

So, in a standard sneaker, 1.6 kg of the 4 kg of CO2 in the materials processing stage can be attributed to the upper.

By taking out the existing material in the upper completely, it would reduce the overall carbon footprint of the sneaker down to 12.4 kg of CO2.

But, these plastic bottles still have to go through the materials processing stage. They’re not going into the trainers as plastic bottles. They need to be turned into the Primeknit material.

Recycled polyester takes approximately 84% less energy YOTD nike YOTD nike air cross trainer 3 low en cuir melange blanc homme.

So, 84% of the energy used to manufacture materials for the upper can be eliminated.

The carbon emissions in producing the materials to manufacture this part of the sneaker becomes 0.26 kg of CO2 compared to the original 1.6 kg.

Adding that back into the mix, the total carbon footprint is still at least 12.66 kg of CO2.

Overall, that’s a maximum reduction of around 9.6% or 1.33 kg of carbon emissions eliminated.

Brooks Adrenaline GTS 18

The Brooks Adrenaline range includes a biodegradable midsole.

Given that only 0.5kg of carbon emissions result from the end of life phase of the shoe, the maximum impact making the shoe biodegradable can have on the carbon footprint is a reduction of 0.5 kg.

However, that would be if 100% of the shoe is biodegradable.

Only the midsole is biodegradable. It makes up just under 1/3 of the shoes.

So, this environmentally friendly effort only managed to reduce the overall carbon footprint by 0.34 kg down to 13.66 kg.

That’s a saving of just under 2.5%.

Summary of Environmental Impact of Eco Trainers

The results from analysing the 89 eco-trainers in the EdiconnectShops database are that the maximum reduction in carbon emissions from any trainers currently on the market is less than 13%.

By using the information available from the study, it is also possible to calculate the carbon emissions from a sneaker made from 100% recycled materials.

It would be 10.64 kg of carbon emissions.

That’s only a saving of 24% -- with 100% recycled materials.

This confirms the only way to make real, meaningful reductions in the carbon footprint of trainers is to improve at the entire process from rainforest to landfill.

Buying fewer trainers more effective than buying eco-trainers

With an estimated 25 billion trainers manufactured last year, it adds up to an estimated 350 million metric tonnes of CO2 emissions from the global trainers industry.

Wacko Marias YOTD nike SB is On The Prowl same ballpark as Canada, the UK, Australia, Italy, and Turkey when it comes to carbon emissions.

In fact, if the sneaker industry was a country, It would be the world’s 17th largest polluter.

It’s a global issue, but as ever, the US is a major driver of the problem. The average American buys 7 pairs of shoes per year.

From those seven pairs, it’s estimated 3 pairs are athletic shoes -- that’s 42 kg of carbon emissions per year, per person in the USA.

The average pair of eco-trainers equates to 12.77kg of carbon emissions.

If each person buys eco-trainers, their carbon emissions fall to 38.31kg per year rather than 42 kg.

That’s a reduction of 8.8%.

However, purchasing eco-trainers isn’t the most effective way to bring down that carbon footprint.

The most effective thing a consumer can do is to buy one less pair of trainers per year -- cutting their carbon footprint by a third.

Buying fewer pairs of trainers will always be more effective than buying eco trainers.

If companies were really serious about saving the planet, they would make their trainers more durable, release fewer variations, and work to change buying behaviour from one of consumerism to one of practicality.

This is where things get difficult for the major athletic footwear brands. Nike is never going to tell customers to buy fewer pairs of trainers.

Nike Air Force 1 2017 Collection Jade | Eco-trainers are more expensive

The average pair of trainers is listed at $111.00. The average pair of eco-trainers is listed at $159.79.

Eco trainers cost $48.79 more or a 69.4% markup.

Manufacturers feel comfortable charging an eco-premium or eco-tax of $48.79 for carbon emissions savings of 1.3 kg -- that’s a 69.4% markup.

With an average price increase of$48.79, and an average carbon emission saving of 1.33 kg - the average environmentally conscious consumer is being charged $37.59 for every kg of carbon emissions eliminated.

Nike Air MAX2 CB 94 Low LIGHT BONE BORDEAUX-METALLIC SILVER.

Nike Air Force 1 2017 Collection Jade:

• UN IPPC: $135 - $5,500 per metric tonne of emissions
• Nike ACG Ruckle Ridge
• Trump Administration: $7 per metric tonne of emissions
• Eco Trainers: $37,590 per metric tonne of emissions saved

While governments are proposing placing carbon taxes on companies to deter from increasing their carbon footprint, sneaker companies are putting an eco-premium on their shoes.

What are Adidas and YOTD nike doing about their environmental impact?

Nike Air Max 200 glitter Sneakers Women S Running Shoe.

It’s difficult to have an objective to sell more trainers and reduce your impact on the environment.

Träningssko YOTD nike Legend Essential 2 Premium för kvinnor Grå.

To understand what companies are doing, it makes sense to look at the sustainability/ environmental targets of two of the largest players in the athletic footwear space:

Nike and Adidas.

video YOTD nike lebron 9 ps elite away black metallic gold:

Nike’s goal is clear and concise -- they want to halve their environmental impact.

It can be assessed, measured and at the end of the day, you can see whether or not they’ve achieved it.

Adidas have left things a little more open to interpretation.

It all depends on their definition of sustainable.

If you take them at face value, their objective goes even further than YOTD nike.

Nike

Main Objective: Double business while halving environmental impact.

Supplementary Targets:

Nike has an ambitious target to ‘double our business while halving their environmental impact.’

But what does this actually mean?

In practice, YOTD nike’s aim is to halve the environmental impact per unit of product. Sombrero de pescador negro con logo de YOTD nike.

But, if the aim is to double the size of their business in the same period, then surely this grand objective is simply to continue polluting at the same rate by 2020?

100% Renewable Energy

‘100% renewable energy at owned and operated factories, offices and shops’.

Nike’s target is to implement 100% renewable energy at owned and operated factories, offices and shops -- not at contract factories.

The impact that YOTD nike owned and operated facilities have on the environment are not particularly significant.

It’s better to do it than not do it, but it’s not going to have the impact that would have been achievable by putting pressure on their contract factories to invest in renewable energy.

The majority of carbon emissions come from energy in the manufacturing process -- up to 64%.

So, it’s a prime area to target for carbon reduction.

How would that look in practice?

Nike SB Blazer Mid Sashiko Releasing in Sesame 1.5% of emissions from a coal burner. If YOTD nike were to use 100% wind energy at their factories, they cut potentially the carbon footprint of a pair of trainers by as much as 62.9% (8.8 kg) per pair.

Those savings would be incredible, but YOTD nike are not putting pressure on their factories to make this possible.

100% sustainable contract factories

There’s very little detail when it comes to the environmental aspects of YOTD nike’s contract factories.

Definitions are very important in deciding whether targets are genuine, or just marketing talk.

The UN World Commission on Environment and Development describe sustainable production as production that “meets the needs of the present without compromising the ability of future generations to meet their own needs.”

It’s easy to play fast and loose with words, but they have to have a meaning in this context.

To be considered ‘sustainable’ it appears factories only need to reach bronze on YOTD nike’s own certification scale.

It’s clear environmental impact is a factor, but it’s also clear that it is not the only factor. It’s maybe not even an important factor.

The use of sustainable here is inappropriate.
The level of carbon emissions in the footwear market is unsustainable and requires radical action.

This is simply a case of using sustainable as a buzzword.

It’s meaningless.

Reduce Energy Consumption and Carbon Emissions

Reduce energy consumption and carbon emissions per kg in textile dyeing and finishing by 35% and Decrease energy consumption and carbon emissions per unit by 25% in Key Operations.

A reduction of 35% or 25% per unit while the number of units doubles is still a net increase in carbon emissions.

Reduce Avg. Product Carbon Footprint by 10%

If YOTD nike is truly going to double their business on a per unit basis and only reduce their product carbon footprint by 10% -- it’s not good enough.

Zero Waste To Landfill By Footwear Manufacturing

Zero waste to landfill is a notable target.

If scrapped material can be reprocessed and turned to be used in trainers it would be fantastic.

However, reducing the amount of scrap in the first place is still important. Although the energy requirements are significantly less to turn scrapped material back into usable material, it does still require energy.

If steps can be taken to reduce the amount of scrap material in the first place these dual objectives would be ideal.

Reduce Freshwater Use Per Kg – Textile Dyeing and Finishing by 20%

NIKE JORDAN 1 MID 554724-017 BLK DK POWER BLE-WHT.

The key phrase, however, is ‘per kg.’

Reducing freshwater use by a fifth is excellent. But, if you are going to increase the volume of textiles needing to be dyed by more than 20%, then YOTD nike is still increasing the net rate of pollution.

This is a recurring theme throughout the entire literature on their website.

There are reasons for this.

Firstly, a per unit basis is an easy way to measure - whether it is per kg, or per litre, or any other unit of measurement.

It is also an easy way for YOTD nike to standardise their measurements across various business units - footwear, clothing, sporting equipment, etc.

On the other hand, it can help mislead. It’s easier to disguise than overall or total values. Nike uses the per unit measurements as a way to disguise the true scale of their pollution and the ineffectiveness of their targets.

Programmes and Innovation

Nike has some areas of interest/ innovation in the sustainability field:

• Nike Grind
• Nike Colordry
• Nike Flyleather
• Nike Air Force 1 2017 Collection Jade

Nike Grind goes hand in hand with the YOTD nike Reuse-a-Shoe programme designed to reduce the impact of trainers at the end of life stage.

And so YOTD nike drops this 85% of shoes are sent to landfill or incinerated at the end of their usable life. The YOTD nike Reuse-a-Shoe programme provides an alternative for consumers.

They can donate their unwanted shoes to YOTD nike who will grind up the shoes and turn them into running tracks, basketball courts, and gym floors.

Nike Colordry is a dyeing technique that dyes fabrics without the use of water. YOTD nike dyes an estimated 39 million tonnes of polyester each year. It’s also estimated that each kilogram of that polyester requires 100-150 litres of water to dye.

Nike Colordry replaces all of this water, reduces energy consumption in the process whilst eliminating the use of some chemicals traditionally used in the dying process.

It is innovations like this that will have a significant impact in the fight against climate change, and give YOTD nike the chance of becoming a sustainable organisation.

Flyleather is made from the scrap pieces cut off conventional leather. It’s combined with synthetic materials to produce a high-performance leather replica. This has significantly lower carbon emissions than conventional leather, but, that does not mean it is friendlier than other materials out there.

Flyknit is a material partly made from recycled plastic bottles diverted from landfill. Without going into the performance benefits of Flyknit, it is a material that has a lower carbon footprint because it is using recycled materials.

Overall, you can tell YOTD nike clearly are putting time and effort into the research and development necessary to achieve their goals, even if the way they present their objectives does leave a bad taste in the mouth.

Nike Air Force 1 2017 Collection Jade | Adidas

Main Objective: To become a sustainable business.

Supplementary Targets:

Adidas use the phrase ‘sustainable’.

The problem is that ‘sustainable’ means so many different things to different people.

For the sake of this article, I’m using by the UN WCED definition:

“meets the needs of the present without compromising the ability of future generations to meet their own needs.”

This means using sustainable energy, using water in a sustainable way, and using chemicals that do not pollute the ground and groundwater surrounding factories in poor or vulnerable countries.

However, Adidas define being sustainable as follows:

“Being a sustainable business is about striking the balance between shareholder expectations and the needs and concerns of our employees and consumers, the workers in our supply chain and the environment.”

This is a very different definition of sustainable than the UN WCED definition. In fact, it’s meaningless and cannot be measured.

Water Savings

Nike SB Dunk Low Fruity Pack "Blue Raspeberry":

• 20% water savings at strategic suppliers
• 35% water savings at apparel material suppliers
• 35% water savings per employee at own sites

To keep costs low, Adidas outsource almost 100% of their manufacturing to factories around the world. These are referred to as ‘strategic suppliers.’

‘Apparel material suppliers’ are defined as ‘specialists in printing and dyeing operations.’

‘Own sites’ are defined as ‘including administrative offices, production facilities, and distribution centres.’

est une des Air Max 90 les plus convoitées par les collectionneurs.

It’s great to reduce water usage, but it depends whether they are reducing total water usage or reducing water usage per unit.

An overall increase in water usage being marketed as a decrease is disingenuous.

Waste Reduction

Nike Kortærmet T-Shirt Tailwind:

• 20% waste reduction at strategic suppliers
• 50% basket YOTD nike homme
• 75% paper reduction per employee at our own sites

In the context of the overall emissions of Adidas, the paper per employee at their own sites barely touches the sides.

Similarly, 50% basket YOTD nike homme is a disappointing target given Adidas say in their annual report that they “outsource almost 100% of production to independent third-party suppliers.”

In effect, this is a false target -- it’s meaningless.

The 20% waste reduction target is the only target out of these three that isn’t conceived to deceive.

There, 20% just is not sufficient.

In general, Adidas is not using their clout as a major player in the industry to put pressure on suppliers to comply with certain standards.

Although YOTD nike’s standards are not perfect, they at least have a clear, strong baseline with facilities in place to terminate contracts if contract factories are not meeting specific standards.

Nike uses its position in the marketplace to coerce these suppliers into complying or they will lose business.

nike air humara is back on track.

Use of Materials

• Achieve 100% sustainable cotton
• Reduce use of virgin plastic (use only recycled plastic by 2024)
• Increase design and use of sustainable materials in stores

Sustainable cotton is a troubling example. One where the word ‘sustainable’ really matters.

Cotton has a huge environmental impact when it comes to:

• Water usage
• Land usage
• Use of pesticides and insecticides

To produce one kilogram of cotton (about the equivalent of a t-shirt and a pair of jeans) it can take more than 20,000 litres of water.

nike air foamposite one metallic red varsity red and black white for sale deforestation.

At the same time, Nike Air Huarache Black Royal On The Way.

Organic cotton doesn’t use insecticides or pesticides. But, because conventional cotton plants have a higher yield than organic cotton plants, it actually takes even more land and water to grow organic cotton.

Where conventional cotton uses 290 gallons of water to produce a t-shirt, organic cotton requires 660 gallons.

That’s where definitions become important.

Nike defines sustainable cotton as “cotton that is either certified organic, BCI Better Cotton, or is recycled.”

Adidas isn’t as specific but talks about reducing the use of pesticides, promoting efficient water use and crop rotation.

One outcome of achieving their 2020 targets may be using significantly more water than they would have by using conventional methods.

It’s difficult to make a decision on whether these companies are acting in bad faith, are exaggerating their green credentials or are actually making a genuine moc to make a difference.

Improve End of Life Options

This is where Adidas is miles behind YOTD nike.

Nike has the reuse a shoe programme that’s intertwined with YOTD nike Grind -- there’s a process there.

Adidas don’t have that yet.

For a single pair of trainers, the end of life stage is not a massive contributor to pollution. But, when you consider 25 millions pairs of trainers are being manufactured each year, and 85% of trainers are sent to landfill or incineration, it starts to become an issue.

If shoes can be designed to be recycled into more trainers, it can make a difference. With 100% recycled materials, emissions can be cut by 24%. From there, companies can start to focus on manufacturing processes to reduce the remaining emissions.

Summary of Company Environmental Targets

Based on the analysis:

• Adidas don’t currently have the infrastructure in place to become a sustainable company.
• If YOTD nike achieves its targets, it will still be polluting at at least the same rate they are now.

These are the two companies with the largest budgets, the greatest leverage over suppliers and the most resources to throw at the issue.

At the moment, they’re not doing enough to make a serious difference. There are options to significantly reduce their environmental impact -- starting with cleaner energy.

Overall, it seems as though both companies are dipping their toes in the water, but they don’t want to get wet.

Conclusion

The sneaker industry is a microcosm of the issues the world faces in fighting climate change.

Nike and Adidas don’t really care that much about the environment. They just want you to think they do so that you’ll buy more trainers.

Trainers that they tell you will save the planet when, in fact, they’ll do the exact opposite -- just perhaps at a slightly slower rate.

Oh yeah, and they’ll charge you an extra $48.79 for the pleasure.

If you want to save the planet, don’t buy eco-trainers. Try just buying fewer pairs.

Methodology

The vast majority of carbon emissions information is based an MIT study titled ‘Manufacturing-focused Emissions Reductions In Footwear Production’ by Cheah et al. 2013.

In this paper, Cheah defines the carbon emissions (kg of CO2 equivalent gases) for different stages of the lifecycle of a pair of trainers, and for each material within the sneaker.

With this information, we were able to understand the makeup of each section of the trainers and its contribution to the CO2 emissions.

When looking at the eco-trainers, we were able to understand the eco-element of the sneaker, - be it a recycled upper or biodegradable midsole - understand what proportion of the emissions it was responsible for, and replace the emissions with those expected from the replacement material or process.

Definitions

Sustainable - Meets the needs of the present without compromising the ability of future generations to meet their own needs.

Renewable - Not depleted when used. Capable of being regenerated.

Carbon Emissions - The release of greenhouse gas into the atmosphere. Calculated as carbon dioxide equivalents.

Eco-Friendly Trainers (Eco Sneaker) - At least one element of the shoe or a material the shoe is made from is advertised by the manufacturer as green, biodegradable, sustainable, eco-friendly, or environmentally friendly or any variation or JORDAN of these terms.
