Printing and paper publishing have traditionally been perceived as the eco-friendlier option because they are physical copies on paper. Still, if you dig deeper, it turns out the gap between print and online materials is much less significant than people might assume. The environmental cost of a printed leaflet mostly comes from the use of the paper, printer ink, packaging, and shipping materials, whereas the digital one’s environmental toll is spread out across a number of components such as data centers, network traffic, and the electronic device in the user’s hand. The result is that, even though a digital reading might look lighter on the environment, it’s actually more challenging to determine and the risks are more underestimated.

The real honest story is that neither of the two media can be put in a box with a fixed carbon figure. For instance, a book which is printed on 100 per cent recycled paper at a mill certified under the principles of environmental management is shipped locally and so, the environmental impact per reader of that print book might be less than an electronic one where the user loads images of very high resolution without compression and continues reading for 45 minutes on a computer connected to a grid with a major proportion of coal generation. That example is quite rare, but still, if something is an exception, then it has some weight because the exception reveals to us which measures need to be taken seriously.

What Goes Into a Printed Brochure’s Footprint

The main contributor is usually the paper or cardboard product itself. Most of the carbon dioxide emissions during the whole life cycle can normally be attributed to the process of making the pulp and paper, as well as the energy consumed during processing at the factory. The printing activity itself adds a minor portion compared to people’s expectations. A difference of 85% in fiber sources can be a big deal. If a forest is certified well that produces virgin fiber then it will have a much better environmental footprint than the one producing paper from virgin fiber not certified at all. Besides that the production of the paper can be based either on recycled fiber or on virgin fiber.

The paper weight is what mostly counts. Printing using 100gsm coated stock versus 70gsm uncoated stock can bring significant differences in both the paper input and freight emissions, as shipping cost and carbon footprint are proportional to the weight being transported. It is during the product delivery to the market where several retailers fail. A print run manufactured in a country, stocked in another, and delivered personally by mail to households in a third, the transport profile is so vast that it can equal or exceed the paper profile. And finally, there is an issue nobody wants to mention: waste. Industry numbers indicate that a large proportion of unsolicited printed materials gets thrown away immediately without even looking at what it was. All this waste means production and transport emissions, which is the cost you will not recover. In the printing business they like overprinting for they profit from the volume, and so, producing only an additional 10,000 copies costs almost nothing at all while the additional carbon emission is quite a lot

Where Screen-Based Publications Actually Consume Energy

Three places, and they’re unequal. The data center hosting your files, the network moving those files, and the device rendering them. Device use is usually the largest of the three for consumer-facing material, because a phone or laptop screen running for several minutes consumes more energy than the transmission itself.

File size is the lever you control most directly. Eighty pages of uncompressed 300dpi imagery might weigh 200MB, while the same content served as optimized web images with progressive loading might come in under 15MB. That’s more than a tenfold difference in transmission energy, and it also changes how long the reader waits, which changes device-on time. This is why interactive shoppable publications built for the web tend to outperform a PDF dropped onto a server, since the delivery method itself determines how much data ever moves.

Different regions rely on different electricity sources to meet their needs; these mixes heavily affect overall carbon emissions. For example, the electricity used to serve web pages in Norway, Sweden, or France is largely based on hydro and nuclear power, so the amount of greenhouse gas emissions resulting from one kilowatt-hour is quite a bit lower compared with the same files if they had been served to users in Poland, India, or the United States. The same resource, very different outcomes, just because of a change in location.

Video and interactive content can have considerable impact and should That means be examined carefully. An embedded autoplaying video could greatly increase data usage by a reader which results in greater energy use at the source too. In the US for instance, one study identified video streaming as a huge reason of households’ high internet-based energy use. If, in business terms, a video doesn’t justify its existence at all, it surely justifies its carbon.

How the Comparison Changes by Industry and Audience

Stores that sell clothes and home furnishings and that have products changing with the seasons in frequent cycles benefit very clearly from going online. Since they previously had to do four to eight print runs a year they are now able to save a lot of paper by simply reducing their annual print by three runs. Furniture and luxury products are the other side of the story. Publications that people keep and refer to constantly for months and in some cases even show as art pieces are a totally different thing. The thing that a genuine annual use period of 12 months gives is a footprint that is evenly spread out over a much bigger number of reading sessions in comparison with a leaflet that gets wasted within a week, and the nice thing about the real thing is that it helps to sell the product which is not an easy job for a screen to copy.

The second group in this matter contains B2B industrial and industrial buyers because there, the document serves as the main working tool. It is the convenience to the user factor that leads them to go for screens heavily, while it is not their concern as far as environmental aspects are concerned. Carbon footprint reduction becomes an extra which results from a decision that was taken on grounds of practicality.

Cultural or environmental factors also vary the result. For a seller that is selling products throughout the whole of a country like the Netherlands, distribution distances are very short and the electric supply is pretty clean. Because of this, both printed format and online format seem a better solution than it would for a seller printing stuff and shipping them all around the continental US.

Measuring It Without a Full Lifecycle Assessment

You’re not obliged to go through a consultancy to get an accurate figure either. For printed materials, you can multiply the weight of the printing run by the published emission factor for the paper grade you’re going to use, then add fuel cost based on the distance and tonnage. Generally paper suppliers are ready to give this info to you as soon as you ask for it. Besides that, quite a few of them are including the factor as part of the price offer automatically.

As for the web part of the story, find out the total data transferred (average size of the file number of sessions) then calculate the electricity consumed in data delivery using a published energy efficiency value for data delivery, and also take into account what energy the device consumed based on how long the user was on the page. The answers will only serve you as approximate values Yet it is precisely the approximation of values that leads you to the right understanding of which areas require your attention that is the objective. Should your files be 180MB large and you reach 50,000 views, you are doing nine terabytes of transfer. From now on, it is very simple to recognize that by reducing file sizes, which is known as optimizing your assets, you will achieve the largest impact.
