What Net Zero Means for Packaging
The UK has committed to achieving Net Zero greenhouse gas emissions by 2050. As businesses continue to reduce their environmental impact, packaging has become one of the most practical areas for lowering emissions and demonstrating environmental responsibility.
But Net Zero is not just about replacing plastic - it involves considering the entire lifecycle of packaging materials, from how they are sourced to how they are disposed of.
In this guide, we will explain how emissions are produced in packaging development, ways your business can reduce packaging emissions, what Net Zero actually means, and how modern polythene materials support sustainability.

What Does Net Zero Actually Mean?
Net Zero emissions means reducing greenhouse gas emissions as much as possible and balancing any remaining emissions by removing an equivalent amount from the atmosphere.
Although Net Zero and carbon neutral are often used interchangeably, they have different meanings.
Carbon neutral focuses on balancing carbon dioxide (CO₂) emissions by reducing them where possible and offsetting the rest through verified carbon reduction projects.
Net Zero is broader, covering all greenhouse gases, including methane and nitrous oxide. It prioritises cutting emissions across operations and supply chains, with offsetting used only where emissions cannot be eliminated.
For many businesses, Net Zero forms part of wider Environmental, Social, and Governance (ESG) commitments. Packaging plays an important role because every packaging decision affects a product's overall carbon footprint. Emissions occur throughout the packaging lifecycle, from raw material extraction and manufacturing to transport and disposal, but they can be reduced through smarter material choices, increased recycled content, lightweighting and improved recyclability.
Why Packaging Plays Such an Important Role
Packaging affects emissions at every stage of the lifecycle, making it one of the most effective areas where businesses can reduce their overall carbon footprint. The key stages of the supply chain include:
- Raw material extraction
- Manufacturing
- Transportation
- Storage
- Product protection
- End-of-life disposal or recycling
Procurement teams play an important role in reducing emissions by selecting packaging that balances performance, cost, recyclability, and carbon impact across the entire supply chain.
Well-designed packaging can help lower emissions in several ways, from preventing product damage and reducing transport weight to improving recyclability at the end of its lifecycle. Small changes to packaging materials and design can therefore have a significant impact on a business's overall environmental footprint.
It’s Not Simply About Using Less Plastic…
It is important to recognise that achieving Net Zero packaging does not mean just using less plastic or removing it altogether. It also involves a range of other decisions for businesses to consider, including:
- Material Efficiency: Using the minimum amount of material needed to achieve the required level of performance, helping to reduce waste and improve sustainability.
- Product Protection: Designing packaging to protect products from damage during storage, handling, and transport, reducing waste caused by returns or replacements.
- Recycled Content: Packaging made using materials that have already been recovered and reprocessed for reuse, helping to reduce demand for virgin plastic. Increasing recycled content can also help businesses reduce liability under the UK's Plastic Packaging Tax.
- Lightweighting: Reducing the weight of packaging without compromising its strength or performance, enabling businesses to use less material and lower transport emissions.
- Recyclability: Designing packaging so it can be easily collected, processed, and recycled into new products at the end of its life.
- Overall Lifecycle Impact: The total environmental impact of packaging across its entire lifecycle, from raw material extraction and manufacturing to transport, use, and end-of-life disposal or recycling.
It is important to note that, in some applications, lightweight recyclable polythene can produce a lower overall carbon footprint than heavier alternatives because less material is used and transport emissions are reduced. This can make it a more sustainable packaging solution.
Practical Ways Businesses Can Reduce Packaging Emissions
Here’s how businesses can reduce their packaging emissions throughout the material lifecycle:
Increase Recycled Content
PolyPCW™ is packaging made from post-consumer waste (PCW) that has already served a purpose. This means it is a recycled form of packaging.
The benefit of a material such as PolyPCW™ is that it reduces waste and material used, without compromising material performance.
By using PolyPCW™ material, your business can increase your post-consumer recycled content by at least 30%, and possibly as much as 100%. This is done while maintaining the strength and durability of the material for demanding industry use.

Use Less Material
Lightweighting of packaging is the process of designing packaging that is lighter and uses less material than traditional packaging, but has the same level of strength and durability.
One example is Polylite™. This has the same strength as conventional polythene, which reduces weight and use of plastic by up to 20%. This creates lower costs, less waste, and, for your Net Zero and sustainability goals, a lower carbon footprint!

Choose Renewable Materials Where Appropriate
Bio-based materials are those which are either wholly or partially created from biological resources such as plants, rather than man-made sources.
Polyair™ material is made entirely from renewable sugarcane waste. It has other notable benefits, including being a carbon-neutral film and being 100% recyclable, and yet it maintains the same level of high performance as conventional polythene.

Improve Recyclability
Designing packaging with recycling in mind starts with material choice. Mono-material packaging uses a single material, such as Polyethylene, rather than combining several plastics together. This makes the packaging easier to sort and process at recycling facilities, as mixed-material versions must be separated before they can be recycled.
Clear recycling guidance supports this further. When packaging includes straightforward instructions on how it should be disposed of, customers know exactly what to do with it once they have finished using it. This reduces the number of items placed in general waste by mistake and improves the overall quality of the material collected for recycling.
Closed-loop thinking brings these principles together. Rather than treating packaging as something used once and discarded, businesses can design it to stay in circulation. This means collecting packaging after use, recycling it into new material, and using that material to manufacture new packaging - keeping resources in use for longer and reducing reliance on virgin plastic and extraction of new resources.
Reduce Packaging Waste
Reducing packaging waste starts with using only the amount of material needed to protect a product throughout storage, transport, and handling. Right-sizing packaging and reducing excess film can help lower material use without compromising performance.
Well-designed packaging also prevents damaged goods, reducing the need for replacement products and unnecessary waste. Optimising pallet stability and load security can further improve transport efficiency by helping products arrive safely while making better use of available space.
How Sustainable Polythene Supports Net Zero Goals
Modern polythene has evolved significantly, with manufacturers developing solutions that help businesses reduce their environmental impact without compromising performance. Today's sustainable films are increasingly designed to:
- Have more recycled content
- Are more lightweight
- Be compostable (where suitable)
- Have renewable material innovations
- Deliver improved performance
However, there is no single packaging material that is right for every application. The most sustainable choice depends on factors such as the product being protected, transportation requirements, recyclability, and overall lifecycle impact.
Selecting the right packaging is about finding the best balance between performance, efficiency, and environmental responsibility.
Questions Businesses Should Ask Their Packaging Supplier
When deciding on the right packaging for both your use case and sustainability goals, you should consult your supplier to make sure you choose the right option for your situation.
You should consider asking questions such as:
- Can recycled content be increased?
- Can film thickness be reduced?
- Is there a lower-carbon alternative?
- Is the packaging fully recyclable?
- Can packaging performance be maintained while reducing material use?
- What evidence supports sustainability claims?
A knowledgeable supplier should be able to answer all of these questions with clear evidence to support any sustainability claims.
