Reverse Logistics: A Frontline Player in Reversing Climate Change

Author: Sheldon Miller, Founder & CEO, STOCS

Reverse logistics has a frontline role to play in the fight against global warming and climate change, says SHELDON MILLER, the Founder and CEO of the start-up STOCS, a 20 plus year veteran of reverse logistics and a former journalist.


Firstly, what I always find inspiring about the RLA is the vast experience of its membership base. 

Many of us have been in reverse logistics for many years, some of us for decades, working tirelessly out of the limelight to improve processes, inputs & outputs at the ‘back end of retail’. 

Not just out of the media limelight but often well out of the limelight of the retail industry and, for many, even well out of the limelight of their own retail companies. Many, many years ago before LinkedIn, when you called a retail enterprise main line the folks answering as gatekeeper wouldn’t even know the reverse logistics department even existed, let alone who the reverse logistics folks were, their names or their extension numbers!   

For decades retail was all about front line sales and to a large degree that is still somewhat the case. But the times, they are changing and 2019 sparked big change. 

Since COVID a bright light has shone on Reverse Logistics far brighter than ever before. 

The global pandemic and supply chain blockages created a perfect storm of bricks & mortar retail lockdowns and an unprecedented surge in online purchases, with a staggering subsequent increase in returns, averaging a 21% return rate. With global supply chain squeezes, we saw the back end of retail literally become the front end, as new products were in scarce supply and reuse products and parts become high in demand.  

Suddenly supply chain was in the news and the mainstream media discovered our reverse logistics industry like a discovery of fire.  

The eyes of the World were upon us, as the media discovered this thing called the ‘secondary market’ and this ‘new’ World of enterprise returns, resale and bargain discoveries. Following the media interest was the investor interest.   


Reverse logistics had entered a brave new World.  

And what a World it is; where no two days are the same and we are kept constantly on our feet, having to be adept and nimble problem solvers and reverse logistics ‘plumbers’ dealing with many supply chain plumbing issues: burst pipes, leaks and floods, in a retail sense. Working out how we put square pegs into round holes, at speed & scale, efficiently and effectively. 

Never a day goes by without a challenge but whilst the challenges are omni-present they have become omni-channel and multi-faceted and way more complex than ever before, in a hybrid offline and online transitioning world. 

We could be forgiven for thinking the COVID was the greatest challenge but there is one even bigger and with far greater stakes at play and with a burning platform: 


Unless you defy all logic and factual findings of Science, you will know that global warming and climate change is our greatest challenge to date of the 21st Century. Whether you embrace or denounce the facts at hand, every human bar none will be affected and every human on this planet has a role to play in the fight against climate change. 

Regardless of race, colour, country or creed, we all have skin in this game and the climate clock is ticking. 

Time left to limit global warming to 1.5°C is 5 years. 

That is the cold, hard fact as the Earth simmers to the boiling point. 

If we do not act, global sea levels will rise by at least 1.5 feet by the end of this century. Low lying lands like Florida will be hugely impacted, with 60% of Miami under water potentially by 2060.    

In February it was confirmed that the 1.5°C threshold of global warming has been breached for a full 12 months for the first time, according to the EU’s Copenicus Climate Change Service. Although it doesn’t break the commitments of the Paris Agreement.

The Paris Agreement is a legally binding international treaty on climate change. It was adopted by 196 Parties at the UN Climate Change Conference (COP21) in Paris, France, on 12 December 2015 and entered into force on 4 November 2016. 

Its overarching goal is to hold “the increase in the global average temperature to well below 2°C above pre-industrial levels” and pursue efforts “to limit the temperature increase to 1.5°C above pre-industrial levels.”

Having almost clocked up the first quarter of the 21st Century, it is apparent that tackling global warming and arresting climate change to achieve the Paris Agreement treaty action plans is the greatest challenge we face as humans and could be the most defining aspect of this century. 

The challenge is so great and so vast it is often overwhelming.   

But we in reverse logistics can play our part and it’s actually a part we can play and influence more than most, to reverse engineer global warming and climate change.

Decades long talk about global warming and climate change has 99% of the time focused on fossil fuels and carbon dioxide. This is right to a large extent but the overwhelming focus on CO2 has mostly overlooked a greenhouse gas with far greater adverse impact on a per unit tonnage emission basis. 

It’s time we started talking about… 


Firstly, let’s talk science and it’s time to brush up on our old school days and aa bit of chemistry: 

Carbon Dioxide (CO₂) consists of one carbon atom and two oxygen atoms. It is a colorless and odorless gas at standard temperature and pressure.

Methane (CH₄) is made up of one carbon atom and four hydrogen atoms. It is also colorless and odorless.

The primary source of CO₂ is the combustion of fossil fuels (like coal, oil, and gas) and the respiration processes of living organisms. It is also released during the decomposition of organic materials and volcanic eruptions.

Major sources of methane include decomposition of waste in landfills, agriculture (especially from the digestive systems of grazing animals), and leakage from natural gas systems. It is also emitted during the production and transport of coal, oil, and natural gas.

Although both gases trap heat in the atmosphere, methane is much more damaging at doing so on a per-molecule basis. Over a 20-year period, methane is approximately 84-87 times more potent as a greenhouse gas than carbon dioxide. However, CO₂ is more abundant and remains in the atmosphere much longer, contributing to long-term warming.

Methane does have a shorter atmospheric lifespan, about 12 years, compared to carbon dioxide, which can remain in the atmosphere for thousands of years.

Understanding these differences is crucial for developing strategies to combat climate change, as mitigating emissions from both gases can have significant impacts on the global climate.

So reverse logistics doesn’t just have a role to play; we have a frontline role in the fight against global warming and climate change, with no time to waste. 


It’s a fair comment to make that Europe is ahead of the sustainability curve. In our space of reverse logistics, the EU was the first to bring in legislation in 2012 to tackle electronic waste with the WEEE Directive (Waste from Electronic and Electrical Equipment). The UN estimates that the volume of electronic waste is rising five times faster than recycling rates and e-waste is now one of the fastest growing waste streams, including mobile phones, computers, televisions, fridges and household appliances.  

The EU’s subsequent and most recent Right to Repair directive forces manufacturers to make it easier for consumers to repair their products. The directive will initially only cover household goods like phones, washing machines and vacuum cleaners but it is estimated it will save customers €176.5bn over the next 15 years and prevent the emission of 18.4m tonnes of CO2. The hope is Right to Repair will extend to wider products and tackle the make, take, waste throwaway consumer culture. 

US State Legislature details that some States have followed in the EU’s footsteps with Right to Repair Acts passed by some States (notably California, Colorado, Minnesota, New York) but failed in some states and still pending in many. 


Whilst the wheels of state and federal politics and legislation take some time to turn, the wheels of private enterprise and, particularly start-ups, are much faster to do so. 

In the last few months, methane emissions from US landfills alone have been found to be 40% greater than originally estimated. 

There are approximately 1,200 open landfills in the US. Methane from these landfills make up roughly 20% of all global emissions of the gas and is the third biggest source after agriculture and fossil fuels.  

Although it’s relatively simple to measure the amount of methane in the atmosphere, it’s harder to pinpoint where it’s coming from. However, NASA scientists are using several methods to track methane emissions and are starting to identify the super emitters. 

There are 200 active landfills in 18 states that participate in the US Environmental Protection Agency’s Greenhouse Gas Reporting Program. Scientists have found that 52% of surveyed sites had observable point source emissios – meaning it was clear to see they were a direct source of methane.   

Landfills are considered the third largest source of human-caused methane emissions in the U.S., responsible for 14.3% of methane in 2021 and emitting the equivalent to greenhouse gas (GHG) emissions from nearly 23.1 million gasoline-powered passenger vehicles driven for one year, according to the US Environment Protection Agency (EPA).

Despite the climate impact of landfills, understanding of these emissions is largely limited to model-based estimates, and the sector remains under-addressed compared to other big methane sources like oil and gas. Traditional surface-based surveys with handheld methane sensors provide an incomplete picture of emissions. This is due to factors like limited access to many sections of active landfills as well as logistical and personnel safety reasons.


Which is why scientists are looking above and beyond to establish an accurate overview to measure the real size of the problem and to capture the single source of truth…from space. 

In the next few months a specially built satellite called Tanager 1 will be launched. Its mission will be to capture global methane using an imaging spectrometer to detect, pinpoint and quantify point source emissions of methane and carbon dioxide. 

For all of us in the RLA, back on Earth and terra firma, there’s a great deal we can do to drive positive climate impact by taking a lead frontline role in the fight against climate change, to action reduction to landfill. 

At the RLA EMEA Expo in Amsterdam I’ll be holding a panel discussion on this very topic with leading experts in climate and reverse logistics sustainability and sharing the key insights of in the next issue of RLA Reverse Logistics Magazine of what we can do as an industry at the frontline. Stay tuned.
