In talks about global warming and our efforts to do something about it, most people refer to the carbon footprint of their activities, the things they do, and the products they use. But what does carbon footprint mean? What is included?

In this article, we will share with you the importance of global warming and the value of carbon footprints and life cycle assessments. You will find examples from the cleaning & hygiene industry, applicable in your cleaning operations. 

 

Carbon footprint: the importance of global warming 

Greenhouse Gases (GHGs) are gases that are able to absorb long wave radiation (heat) that is reflected off the Earth's surface. They then reflect this radiation back down to Earth. If there were no GHGs in our atmosphere, the Earth would be too cold for life as we know it to exist. However, as more fossil fuels are burnt and other GHGs are released, the atmosphere can absorb more radiation and so is warming up. This is known as the greenhouse effect (the same mechanism as in greenhouses) and is occurring on a global scale. 

In 2014, a report on climate change was published based on long-term scientific evidence. This stated that the increase in greenhouse gas (GHG) concentrations (and that is not only carbon dioxide (CO2) but also some other gases such as methane, nitrous oxide, and some more) over the past 100 years has predominantly been caused by human activities.

 

Global warming key facts

  • Both the US EPA and EU Commission say that the increase in CO2 has been close to 50% since the era of the industrial revolution. 
  • Fossil fuel companies and their products have released more emissions in the last 30 years than in the 237 years prior to 1988.
  • Just 100 companies have been the source of more than 70% of the world's greenhouse gas emissions since 1988 the year the Intergovernmental Panel on Climate Change was established. This is according to a 2017 report by the environmental non-profit organization CDP. 
  • The CDP also found that we emit 40% more per year than we did in 1990.
  • The EU aims to be climate-neutral by 2050 an economy with net-zero greenhouse gas emissions. This objective is at the heart of the European Green Deal.

What does carbon footprint mean? 

Think of “carbon” as a shortcut for all greenhouse gases (GHG) that cause global warming—not just CO, but also methane (CH), nitrous oxide (NO), and others. A “footprint” is a way to describe the total impact something has. So, a carbon footprint is our best estimate of the climate impact of an activity, product, lifestyle, company, or even a whole country. 

Why do we use CO equivalents? 

Emissions come from many sources—making electricity, farming, manufacturing—and they’re not all the same. To compare them, we use a common unit called CO equivalent (CO-eq). This converts different greenhouse gases into the amount of CO that would have the same warming effect. For example, methane is much more powerful than CO, so one kilogram of methane equals many kilograms of CO-eq. 

In short: 

  • Carbon footprint = total climate impact of something. 
  • CO-eq = a way to put all greenhouse gases on the same scale. 

 

What is included in the carbon footprint and what is not?

Much confusion around footprints comes down to the distinction between direct and indirect emissions. To give an example: the true carbon footprint of driving a car includes not only the emissions that come out of the exhaust pipe, but also all the emissions that take place when oil is extracted, shipped, refined into fuel, and transported to the petrol station, not to mention the substantial emissions caused by producing and maintaining the car. 

We distinguish different types and scopes of emissions

We distinguish different types and scopes of emissions:

  • Scope 1 (Direct emissions): GHG released from sources owned or controlled by the institution—e.g., natural gas used in boilers, diesel in fleet vehicles, refrigerant leaks, off-gassing from cleaning chemical processes. 
  • Scope 2 (Indirect energy-related emissions): GHG generated off-site in the production of electricity, steam, heat, or cooling purchased and consumed by the institution. 
  • Scope 3 (Other indirect value chain emissions): All other emissions related to the institution’s value chain—includes upstream activities like ingredient sourcing and packaging production, and downstream impacts like product transportation, usage, and disposal. This scope often represents over 90% of an institution’s total carbon footprint. 

Companies like us face the challenge of dealing with complex situations, such as the production of a wide portfolio of products in the same factory or factories, that then are all shipped to different places around the globe. What part of total emissions are attributed to what product? The only practical way to handle this is by proportional attribution, and probably best by volume.  

Life Cycle Assessment and Product Carbon Footprint 

Life Cycle Assessment (LCA) provides a framework for measuring the impact of, for example, a product. LCA assesses various aspects of environmental impact, depending on the LCA method applied.
If you want to assess the life cycle of a product, you need to define what that life cycle actually consists of. The system boundary defines which processes will be included in, or excluded from the system:

  • Cradle to Grave: includes the material and energy production chain and all processes from the raw material extraction through the production, transportation, and use phase up to the product's end-of-life treatment.  
  • Cradle to Gate: includes all processes from the raw material extraction through the production phase (gate of the factory); used to determine the environmental impact of the production of a product. 
  • Cradle-to-cradle is a variation of cradle-to-grave, exchanging the waste stage with a recycling process that makes it reusable for another product, essentially "closing the loop". This is why it is also referred to as closed-loop recycling.

Life Cycle Assessment is a data-intensive, time-consuming activity with the compiling and evaluation of all inputs and outputs and the potential environmental impacts of a product system during a product's lifetime.

Software tools like Ecoinvent, GaBi, or SimaPro combine Life Cycle Assessment modeling and reporting software, and content databases with intuitive data collection and reporting tools to help in comparing impact scenarios. More than a thousand substances are classified and characterized according to the extent to which they contribute to a list of environmental impact categories. It still requires specific technical expertise and experience to complete a full LCA study.
