THE JUNCKERS CARBON CALCULATOR
At Junckers we actively promote sustainable building. Our Carbon Calculator provides a method for choosing the most environmentally friendly flooring solution for net zero carbon building design.
The Junckers Carbon Calculator Tool is a quick and simple way to compare the global warming potential (GWP) and embodied carbon levels of a number of commonly specified floor types including Junckers solid hardwood flooring. When you use the tool you may see that some flooring products cause an increase in the amount of carbon in the atmosphere, but others will actually reduce it. Those that reduce it we call Carbon Negative. Results from the Carbon Calculator clearly show how influential your choice can be.
THE DRIVE FOR NET ZERO CARBON BUILDINGS IS STRONG
Globally the UN Intergovernmental Panel on climate change and the Paris Agreement aim to cut greenhouse gas emissions by 45% by 2030. The government of the United States also comitted to cut America's greenhouse gas emission 50 percent to 52 percent below 2005 levels by 2030. Such initiatives requires architects, contractors, self-builders as well as private customers to specify products with low embodied carbon.
To assess a product’s effect upon global warming you need to know the product’s global warming potential (GWP). This is achieved by measuring all greenhouse gases in the material, including carbon dioxide, and expressing this as a “carbon dioxide equivalent”, CO2e. The greenhouse gases that are generated by extracting, transporting and processing of raw materials, and manufacturing the finished product are used to calculate the product’s GWP, and this is included in the product’s Environmental Product Declaration (EPD).
The Junckers carbon calculator uses publicly available data and draws a simple picture of which materials we can use with no or little worry and those we should leave out if we want to build a greener world.
HOW DID WE WORK IT OUT?
We hope you will find our carbon footprint calculator useful. In the following section you can read more information about it. If you do not find the answer you are looking for, please reach out to us.
WHAT IS THE CARBON CALCULATOR AND WHY DID JUNCKERS DEVELOP IT? add
The sharp increase in CO2 in the atmosphere is the main cause of climate change. In a new 2022 report The UN Intergovernmental Panel on Climate Change (IPDD) documents that we are looking at a temperature rise of 2.5 to 3 degrees Celcius by the end of the 21st century unless the world's countries collectively accelerate efforts to reduce future emissions. It is crucial that we act now with a significantly increased, determined effort.
Climate policies have an impact, but we really need to put our foot on the pedal if we are to fulfil the climate action plans set out in the Paris Agreement. To prevent serious consequences, climate scientists advise the annual level of CO2 emission must be reduced globally. To do this we need more than collective action - personal consumption habits must change too.
So, what will it take? At Junckers, we promote sustainable buildings, and our carbon calculator is intended to help you choose the most environmentally friendly flooring solution. The calculator is designed for architects, contractors, self-builders as well as private customers with the aim to discuss and improve the CO2e (carbon dioxide equivalent) impact from construction.
Junckers wants to make wood a first-choice material - wood is the world's most environmentally friendly raw material, it represents a sustainable way forward. Wood stores CO2 and therefore acts as carbon sink - it absorbs more carbon from the atmosphere than it releases. The environmental benefits of choosing solid wood floors are indisputable. The more timber we use, the more CO2e we remove from the atmosphere which contributes towards mitigating climate change.
The calculator draws a simple picture of which materials we can use with no or little worry and those we should leave out if we want to build a greener world.
WHAT DO YOU MEAN BY ‘CARBON FOOTPRINT' AND WHAT IS CO2e? add
Your individual emissions - carbon footprint - arise from the energy you use for electricity and travel, as well as the energy required to produce your food, products for your home and everything else you buy, whether it is made in the country you live in or elsewhere in the world.
Carbon dioxide equivalent or CO2e is a term for describing different greenhouse gases in a common unit. For any quantity and type of greenhouse gas, CO2e signifies the amount of CO2 which would have the equivalent global warming impact (GWP). We convert all the different greenhouse gases into an equivalent impact from carbon dioxide, the main greenhouse gas. Your footprint in this calculatur is in carbon dioxide equivalent (CO2e).
WHERE IS THE DATA FROM AND HOW RELIABLE IS IT? add
To calculate the footprint for each floor type we used publicly available data based on Environmental Product Declarations (EPD). An EPD is an independently verified and registered document that communicates not only what a product is made of, but the manufacturing process and its impact on the environment. The results for the Carbon Calculator tool are based upon data from specific EPDs that measure the global warming potential (GWP) for the products, rather than using generic or theoretical data. Data is taken from the raw material and manufacturing stages for each product.
Our calculator is based on the following list of EPDs and data from cradle-to-gate including product stage A1: Extraction and processing of raw materials, A2: Transport to the production site and A3: Manufacturing processes

WHAT IS GLOBAL WARMING POTENTIAL (GWP)? add
Global warming potential, abbreviated as GWP, is a term used to describe the relative potency, molecule for molecule, of a greenhouse gas, taking account of how long it remains active in the atmosphere. The global warming potentials (GWPs) currently used are those calculated over 100 years. Carbon dioxide is taken as the gas of reference and given a 100-year GWP of 1.
Carbon dioxide equivalent (CO2e or CO2eq) is calculated from GWP. For any gas, it is the mass of CO2 that would warm the earth as much as the mass of that gas. Thus it provides a common scale for measuring the climate effects of different gases. It is calculated as GWP times mass of the other gas.
WHAT DO THE RESULTS MEAN? add
Junckers solid hardwood floors provide the greatest reduction in carbon levels among all the floor types shown. But there is more to consider. Even though engineered and laminate floors are carbon negative, their life span is significantly less than for solid hardwood floors, thereby placing a greater burden upon raw materials resources and disposal. Floor types such as carpet, vinyl and LVT not only add carbon to the atmosphere, but their life spans are also shorter than solid hardwood, many of the manufacturers use carbon offsettting in their sustainability policies, and often their products cannot effectively be recycled.
Due to its versatility it is often very easy to substitute a Junckers solid hardwood floor for less sustainable products. Here are some examples:
- Sports, Activity and Dance floors - If, instead of specifying a vinyl sports floor finish, you use solid hardwood, e.g. Junckers 22mm SylvaSport Beech, in a 600sqm sports hall you achieve a net reduction of 15,400kg CO2e. You are also using a natural, sustainable material instead of one derived from crude oil.
- Classrooms, corridors, lecture theatres - By choosing solid hardwood in place of carpet, for every 100sqm of flooring you are saving 1,940kg CO2e
- Commercial, Retail - By choosing solid hardwood in place of terrazzo, for every 100sqm of flooring you are saving 1,458kg CO2e
- Public Buildings - By choosing solid hardwood in place of vinyl, for every 100sqm of flooring you are saving 2,590kg CO2e
WHY ARE SOLID HARDWOOD FLOORS MORE ENVIRONMENTALLY FRIENDLY THAN VINYL FLOORS? add
Many factors in the production process can influence the CO2e footprint of vinyl flooring. However, it can be emphasized that oil – not a renewable resource - is an important raw material in vinyl products. In comparison, wood not only stores CO2, it is also considered a renewable and sustainable resource, which explains the difference in CO2e figures.
To some degree, the same positive trend is seen in relation to laminate floors containing wood fibres and paper, as well as engineered floors containing a small part of hardwood, a wood-based intermediate layer, and a bottom layer typically of softwood.
In the production of carpets, great attempts are made to use recycled plastic, e.g., plastic bottles and fishing nets, but many carpet types are like vinyl based on non-renewable resources and will therefore release CO2e to the atmosphere.
MORE REASONS WHY JUNCKERS SOLID HARDWOOD FLOORING IS THE MOST SUSTAINABLE CHOICE
Even though Junckers has always been ahead of its time in caring for the environment, having the right company policies and practices is not enough. We recognise the need to provide independent evidence to clients and designers. We have achieved independent accreditation by a number of international schemes including FSC®, PEFC™ and ISO 14001. We have also had independent product testing carried out for VOCs and our products' effect on indoor environment under CDPH standards and the Danish Indoor Climate Label scheme and have completed EPDs (Environmental Product Declarations) for our floors. These certificates are an important tool for designers who are designing buildings to the high environmental standards required under BREEAM, LEED, WELL and DGNB schemes.
