Before I studied for an MBA at the University of Winchester, I had to persuade the university that letting me onto the course was a reasonable idea. Part of my application was an essay asking a question I already cared about: could paper be part of the fight against climate change?

It was not an entirely neutral choice of subject. I had spent eight years working for Arjowiggins Graphic, marketing recycled and specialist papers to designers, printers, brands and corporate buyers. I had seen products such as Cocoon and Cyclus differentiated through recycled content, appearance, print performance and environmental credentials. I had also watched the graphic-paper market contract as communication moved online and the industry itself came under greater environmental scrutiny.

The original essay argued that paper had been cast too readily as an environmental villain. Several years, one MBA and quite a lot more marketing experience later, I still think that argument contains something important. But I would make it differently now.

Paper can be renewable, recyclable and lower-impact than some alternatives. It is not automatically sustainable because it is brown, fibrous or decorated with a leaf. Plastic is not automatically the worst option in every application either. The meaningful question is not which material looks greenest. It is how the whole system performs.

Why Paper Has an Image Problem

Paper carries a visual accusation. People see a sheet, a box or a carrier bag and mentally work backwards to a tree. The chain feels direct: paper requires wood; wood comes from forests; therefore using paper destroys forests.

That concern is not foolish. Poor forestry can damage habitats, reduce biodiversity and release stored carbon. A paper product made from irresponsibly sourced fibre does not become virtuous merely because it will eventually rot. But the reverse assumption is also too crude. A well-managed productive forest is not the same thing as an untouched ancient woodland, and harvesting does not necessarily mean the total forest stock is shrinking.

Eurostat reported that in 2023, 23 EU countries with available data recorded forest growth above wood removals. Estonia was the exception among the countries reported. That is encouraging evidence at a European level, but it is not a free pass for every paper product. Marketers still need to know where fibre came from, how the forest was managed and whether credible chain-of-custody evidence exists.

This was one of the oddities of marketing paper. The product looked simple, but the buying decision was not. A designer might care about texture and colour. A printer cared about how it behaved on press. Procurement cared about cost and availability. A sustainability team wanted recycled content, certification and defensible evidence. The same sheet could therefore be a creative material, an industrial input, a budget line and an environmental claim at the same time.

The Material Is Only the Beginning

The most useful change in my thinking since the original essay is that I am less interested in declaring a winning material. Sustainability depends on a lifecycle: raw materials, manufacturing, transport, product performance, consumer behaviour, collection and what actually happens after disposal.

That sounds obvious, but packaging decisions are often marketed through a single visible attribute. Paper feels natural. Plastic feels synthetic. Glass feels permanent. Aluminium feels recyclable. Each impression contains part of the truth and leaves out most of the calculation.

A better assessment starts with five questions.

Paper Has Genuine Structural Advantages

Paper's strongest case is not that it is perfect. It is that it begins with a renewable biological feedstock and already operates through a comparatively mature recovery system.

The European Paper Recycling Council reported that 75.1% of paper and board consumed in Europe was recycled in 2024. That includes graphic paper, packaging and tissue. The figure is an industry measure and should be described as such, but it still indicates a collection and recycling infrastructure working at substantial scale.

The industry's operational footprint has also changed. Cepi's 2025 statistics report specific direct carbon emissions of 0.22 tonnes of CO2 per tonne of product across its reporting countries, down from 0.24 in the previous year. Its latest water data indicate that around 90% of water abstracted for paper and board production in 2024 was returned to its source after treatment.

Those figures need careful language. Returned water is not unused water, and an industry average can hide large differences between mills, energy systems and products. Paper-making remains energy- and water-intensive. The relevant point is that the sector is capable of reducing its impact; not that the impact has vanished in a puff of recycled confetti.

Recycled fibre also has limits. Fibres shorten and weaken as they move through repeated cycles, contaminants have to be removed, and some fibre leaves the system through products that cannot be recovered. Virgin fibre therefore continues to enter the cycle. In a functioning circular system, responsibly sourced virgin and recovered fibres support one another rather than acting as moral opposites.

Why Paper Does Not Automatically Beat Plastic

This is where the argument becomes less comfortable and more useful.

A lightweight plastic package can use less material, resist moisture, extend shelf life and reduce transport emissions. Replacing it with a heavier paper alternative may improve recyclability or reduce persistent litter while increasing impacts elsewhere. If the paper package requires a plastic coating, adhesive or barrier layer, its real composition may be less simple than the front of the pack suggests.

A well-known UK Environment Agency study of supermarket carrier bags illustrated the problem. Using its assumptions and 2006-era data, a paper bag needed to be reused at least four times to bring its global-warming potential below that of the lightweight HDPE bag used as the baseline. The precise number should not be treated as a timeless rule: manufacturing, energy and waste systems have changed. What remains useful is the method. Weight, production, reuse and end-of-life behaviour can overturn the answer suggested by appearance alone.

More recent work reaches a similarly inconvenient conclusion. A European Commission Joint Research Centre assessment of single-use and multiple-use food-service packaging found that results varied by product, impact category, recycling rate, transport, washing and the number of reuses. UNEP's broader review put the principle more bluntly: single use is often a bigger problem than plastic itself, while reuse generally offers the stronger direction where the system genuinely supports it.

That is why ‘paper versus plastic’ is usually the wrong contest. The better comparison is package against package, performing the same job, in a defined market, with realistic assumptions about how people will use and dispose of it.

The Paper Bottle Is a Useful Warning for Marketers

When I wrote the original essay, Coca-Cola's paper bottle prototype looked like a vivid sign of where packaging might go. It remains an interesting innovation, but it is also a useful lesson in the distance between a headline and a finished system.

Paboco, the company behind the technology, currently describes its bottle as 85% paper with a barrier containing less than 15% high-density polyethylene. Its stated ambition is a fully bio-based bottle, but the present product is still a composite. Calling it a paper bottle is understandable shorthand; allowing consumers to infer that it contains only paper would be something else.

The same technical problem appears across food and drink packaging. Paper provides stiffness and a renewable fibre base, while other layers deliver moisture, oxygen or light barriers. Tetra Pak, for example, says a typical carton contains roughly 70% paperboard, 25% plastic and 5% aluminium. Its newer paper-based barrier technology raises the paper content and reduces the carbon footprint, but the achievement is meaningful precisely because the difficult layers and trade-offs are being engineered - not because somebody changed the colour of the carton to kraft brown.

This is where packaging development and marketing discipline need to meet. Innovation can be real while the claim is still misleading. A prototype can be promising without being proof of scale. ‘Recyclable’ can be technically true while collection infrastructure is practically absent.

Green Claims Need the Whole Sentence

For marketers, the risk is not limited to choosing the wrong material. It is communicating one environmental advantage as if it settles the entire product.

The Competition and Markets Authority's Green Claims Code says claims should be truthful, clear, substantiated and mindful of the product's full lifecycle. Its guidance gives a simple example: if only the packaging is recyclable, saying the product is ‘recyclable’ can mislead people into thinking the claim covers everything.

The CMA reinforced the supply-chain point in 2026. Retailers, brands, manufacturers and suppliers all have responsibilities for the green claims they make or pass on. A marketing team cannot safely turn a supplier's attractive sustainability bullet point into a broad consumer promise without understanding the evidence beneath it.

European packaging regulation is moving in the same direction. The EU Packaging and Packaging Waste Regulation began applying in August 2026, with measures intended to reduce packaging waste and improve recyclability, reuse and consumer information. For businesses selling across Europe, packaging is becoming a strategic, operational and communications issue at once.

The safest language is often more specific and, usefully, more interesting: ‘made with 80% recycled fibre’, ‘FSC-certified paperboard’, ‘the carton is recyclable where local collection exists’, or ‘this change reduced packaging weight by 18%’. Evidence-rich claims may look less dramatic than a large green leaf beside the word sustainable. They are also much more likely to survive contact with a regulator, a journalist or a reasonably curious customer.

So Could Paper Help Fight Climate Change

Yes - but not merely by replacing every visible piece of plastic with something beige.

Paper has genuine strengths: renewable fibre, high European recycling rates, established collection systems, continuing mill decarbonisation and the capacity to replace fossil-based materials in some applications. It can be an important part of packaging systems designed around lower emissions and better material recovery.

It also has impacts: forestry choices, energy and water use, chemical treatment, weight, contamination, composite layers and finite fibre quality. In some applications, a carefully designed plastic package may use fewer resources or prevent much larger impacts by protecting the product inside. In others, fibre-based packaging offers a clear advantage. The answer belongs to the lifecycle, not the label.

Would I submit the original essay to the University of Winchester today? Probably not in the same form. The question still earns its place, but the conclusion needs less advocacy and more qualification.

Perhaps that is an appropriately MBA-shaped answer. Paper can help. Plastic can sometimes help. Reuse can help most of all. But every claim depends on the system around it - and systems are annoyingly resistant to being summarised by a leaf icon.
