A Life Cycle Analysis, CO₂ Emissions, and Circular Strategies to Reduce Environmental Impact in News and Book Consumption

by Marco Arezio

The choice between reading a paper newspaper or enjoying digital content is not just about personal preference. Behind every printed page, as well as behind every electronic device, lies a complex process involving the extraction and transformation of raw materials, energy consumption, and pollutant emissions, all of which characterize the product’s entire life cycle.

This is precisely the core of Life Cycle Assessment (LCA), a method that helps identify and quantify the environmental impacts generated from the birth of a product (or service) all the way to its disposal or recycling.

When it comes to paper newspapers, the life cycle includes paper production—requiring water and energy consumption, along with the use of virgin or recycled fibers—printing, distribution on a local or national scale, and finally, disposal or recycling.

For electronics, on the other hand, one must consider the extraction of rare metals, the manufacture of delicate components, assembly, long-distance transportation, device use and recharging, and eventually its disposal or reuse at the end of its life.

One important aspect of LCA is highlighting how the peak of emissions and consumption often occurs in an initial phase, such as during the manufacturing of a tablet or e-reader. In contrast, printing a newspaper constantly generates impacts, but in quantities that can be modulated by the number of copies printed.

In short, the overall impact assessment depends on how each of us reads: frequency, the number of texts we consult, and the lifespan of the electronic device are key factors.

Hence, an occasional reader who buys the newspaper from time to time will have a different impact profile from someone who devours newspapers and books, perhaps preferring a single e-ink device that can last for years.

Paper Production: Impacts on Forests and CO₂ Emissions

The paper that makes up newspapers is primarily obtained from cellulose, largely sourced from cultivated trees or managed forests. While there are certification standards such as FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) aimed at ensuring sustainable forest management, there is still the risk that excessive demand for paper might drive producers to rely on wood from uncontrolled sources.

This can lead to illegal or unregulated deforestation, with direct repercussions on carbon sequestration, biodiversity, and the planet’s hydrological balance.

Transforming cellulose into paper sheets also requires significant amounts of water and energy. More modern paper mills strive to optimize the recycling of processing water and use renewable energy for production, but the environmental impact of this industrial phase remains high, especially when demand for paper is rising.

On top of that, transport-related emissions must be considered (moving the wood to the paper mill, the paper to printing facilities, and finally the newspapers to points of sale or readers).

When talking about emissions, we should not forget about the use of inks and chemical additives. Even though many printers are abandoning the most hazardous volatile organic compounds (VOCs), the disposal of certain types of ink can result in the release of substances potentially harmful to the environment.

However, one intrinsic advantage of paper—compared to other materials—is its recyclability. Wherever there are well-functioning recovery processes, it is possible to reduce the amount of virgin resources needed and partially contain emissions.

E-Readers and Digital Devices: Raw Materials and Production Processes

The production of an e-reader, tablet, or smartphone is not immediately visible to the end consumer, yet behind the screen lies an extensive chain of mining, chemical processing, and global logistics.

Rare metals like cobalt, lithium, indium, or rare earths are often mined under critical environmental and social conditions. Mines can significantly impact surrounding ecosystems by polluting water resources and altering the landscape.

Moreover, in some countries, the protection of workers’ rights is lacking, and the hi-tech mineral market may conceal exploitation and child labor issues.

Electronic components—from microchips to displays—require clean-room production environments, with constant temperature control and a large amount of energy for manufacturing processes. Often, these factories are located in Asia, while final assembly takes place elsewhere, and devices are then distributed worldwide: a logistics chain that, although economically efficient, inevitably contributes to CO₂ emissions linked to transportation.

Another crucial aspect is the battery. Rechargeable lithium-ion batteries in e-readers (and even more so in tablets and smartphones) degrade over time and have a limited lifespan. The process of disposing of or recycling spent batteries is complex, and if not managed properly, can release toxic substances into the environment.

However, if a device is built with eco-design criteria and is used for a long time before being replaced, its initial environmental impact—though high—can be offset over several years of service.

Resource Consumption and Waste Management: Paper vs. Electronics

When a reader decides to buy a newspaper at a newsstand or download the latest edition onto their e-reader, they trigger different resource consumption processes.

For paper, the main resource is plant fibers (partly recycled, partly virgin), plus the energy inputs needed to transform them into a finished product. Once read, a newspaper can be recycled a certain number of times (cellulose fibers gradually degrade), providing new raw material for other paper products.

In the case of an electronic device, a single act of reading does not seem to generate tangible resource waste: you are not discarding the “raw material” of a file, nor are you accumulating sheets of paper destined for the trash.However, every download, every software update, and even the operation of the cloud infrastructure require energy consumption in data centers and telecommunications systems. Additionally, when a device reaches the end of its life, disposing of an e-reader or tablet requires a dedicated process to prevent the release of heavy metals or hazardous compounds.

Waste management—whether paper or electronic—remains a central issue in assessing environmental impact. Paper can be collected separately and recycled in many areas, but this is not always the case with electronic devices. In this regard, extended producer responsibility (EPR) policies and the implementation of specialized collection systems can make a difference, boosting the recovery rate of valuable materials and reducing waste and pollution.

Emissions and Energy Balance: Which Is the More Sustainable Solution?

It is challenging to give a definitive answer about which reading method is ultimately more sustainable. There are many variables: how often one reads, the type of energy mix powering production processes and devices, and the user’s behavior regarding recycling or replacement.

Numerous LCA studies have tried to define indicative thresholds. For instance, someone who buys a newspaper daily could, over the course of a year, accumulate a substantial consumption of paper and printing energy. Conversely, if they opted for an e-ink e-book reader and used it for at least two or three years, they would likely offset the initial impact of manufacturing the device.

In other words, for avid readers, a digital solution tends to be more efficient, especially if renewable energy is used for charging and if the device is kept in operation as long as possible.

However, a person who only occasionally reads a paper newspaper might not reap significant environmental benefits from purchasing a dedicated electronic device. Buying a new tablet every year and constantly replacing it—perhaps to get the latest model—negates the environmental advantages of dematerializing paper.

The central issue involves usage frequency, device care, and how it is disposed of or recycled. Thus, the energy balance largely depends on the consumer’s habits and the strategic choices of manufacturing companies.

Reading Habits and Usage Frequency

Technological and manufacturing aspects do not exhaust the topic of sustainability, as reader behavior is a decisive factor. Individual preferences, daily routines, and infrastructure availability impact the environmental profile of one option versus the other.

A user who reads dozens of texts a month, jumping from one newspaper to another and browsing multiple magazines, would likely benefit more from focusing on an electronic device—provided it lasts and is managed responsibly. On the other hand, there is a segment of the public who loves the feel of printed paper, finds the physical format more practical, or perhaps does not have stable internet access.

For these people, continuing to read a paper newspaper may make sense, but it is always important to dispose of it properly or recycle it.

Additionally, there is the concept of the “digital divide”: not everyone has the financial resources or skills to access an e-reader or tablet. In some geographical areas, the newsstand or the library remains the only point of access to information. Thus, opting for digital-only newspapers could create informational barriers for less connected population groups.

Recycling and Circular Economy: Tools for Reducing Impact

In moving toward greater sustainability, both the paper and electronic industries could adopt or refine circular economy models.

For paper, there has long been a particular focus on recycling, thanks to the recovery of newspapers, magazines, and packaging. If well-organized, this practice reduces the use of virgin raw materials and mitigates the impact on forest systems. Besides recycling, it is possible to improve printing processes with more eco-friendly inks, reduce newspaper weight, or handle distribution using low-impact vehicles (electric or hybrid).

For digital devices, the circular economy translates into more modular, repairable designs, allowing for battery or display replacement without having to discard the entire device. Moreover, extended producer responsibility (EPR) means companies take on the obligation of collecting and recycling end-of-life devices, recovering raw materials and limiting the release of hazardous components into the environment.

Finally, choosing to power data centers with renewable energy and implementing advanced energy-efficiency measures can significantly reduce the environmental load of digital infrastructure.

Sustainability and Innovation: Toward a Greener Future for Reading

Looking to the future, we can reasonably expect technological advances that make electronic devices more efficient, reducing consumption and using materials that are renewable or easily recyclable. Meanwhile, the paper industry could improve forest management and implement increasingly low-impact production processes, fueled by renewable energy and supported by water recovery systems and waste reduction strategies.

Public policies could play a substantial role, encouraging sustainable research and innovation and promoting circular business models that reward companies adopting virtuous solutions. For instance, more transparent environmental certifications, tax incentives for ecological production, and proper consumer education could help transform the editorial market, whether for paper newspapers or digital books.

Ultimately, choosing between paper and digital is not solely about convenience or the allure of technology; it also involves a broader reflection on how we interact with the planet’s resources.

On one hand, paper is still a recyclable, tangible, and culturally ingrained material; on the other, digital reading can dematerialize a vast amount of content, theoretically avoiding the constant production of physical copies, but at the cost of an initial manufacturing phase and continuous energy consumption on a global scale.

In essence, sustainability does not boil down to a single gesture but is built through a series of consistent decisions, from designing an electronic device to managing its disposal, and from purchasing a printed newspaper to recycling it afterward.

In a world where natural resources are limited and climate change becomes ever more pressing, each of us bears the responsibility to stay informed and act with awareness. By comparing paper newspapers and e-readers, we can seize the opportunity to rethink not only our reading habits but also our relationship with the goods and services we consume, thus paving the way for a greener and more inclusive future for everyone.
