Sustainability isn’t just a buzzword anymore; it’s a top priority for both consumers and businesses. Packaging, particularly plastic, often takes center stage in these discussions about environmental impact. Beyond concerns around waste management and end-of-life disposal, one key question is how packaging contributes to greenhouse gas (GHG) emissions.

Every stage of a packaging material’s lifecycle—from raw material extraction to manufacturing, transportation, and disposal—is associated with energy consumption and GHG emissions. Understanding these impacts, especially in terms of energy use, is critical for businesses looking to make informed decisions that align with consumer demand for sustainability while maintaining efficiency and profitability.

Why Sustainability in Packaging Matters 

Reducing packaging-related emissions aligns directly with global climate change priorities. Decisions about packaging not only drive environmental outcomes but also help businesses align with Environmental, Social, and Governance (ESG) goals. For some industries, particularly agriculture, mitigating climate impacts is directly tied to long-term viability.

For businesses across sectors, sustainability in packaging has evolved from a responsibility into a necessity. Consumers increasingly prefer brands that take measurable steps toward environmental responsibility. Sustainability isn’t just a moral imperative; it’s a competitive advantage.

According to a recent McKinsey report, approximately 60 to 70 percent of consumers are willing to pay more for sustainable products, particularly in categories such as food, beverage, and personal care. This highlights the growing demand for eco-friendly solutions and emphasizes the importance of businesses adopting sustainable practices to meet consumer expectations and remain competitive in the market.

The Case for Lifecycle Analysis (LCA) 

When evaluating packaging materials, making decisions based on surface-level traits like recyclability or initial production emissions doesn’t capture the full picture. A Lifecycle Analysis (LCA) offers a robust, data-driven approach by examining the environmental footprint of materials across their entire lifecycle. 

Key Factors Assessed by LCAs:

Energy Consumption and GHGs: How much energy is required at each stage, and what are the corresponding emissions? 

Durability and Waste: Longer-lasting materials may reduce the frequency of replacements, but recyclability ensures waste materials can contribute to a circular economy. 

Infrastructure Compatibility: Consider how easily existing waste management systems can handle materials for composting, recycling, or disposal. 

Want to know how your current packaging measures up? Our LCA Tool equips businesses with the actionable insights needed to make smarter, more sustainable packaging decisions. This tool provides you with the data you need to assess water usage, energy efficiency, and GHG emissions across the lifecycle of your packaging materials. 

Comparing Materials and Trade-offs 

Choosing the most sustainable packaging option means understanding the benefits and trade-offs of each material. Here’s a breakdown of the environmental implications of key packaging types to help you make informed choices. 

Plastic

Strengths: Plastic is lightweight and energy-efficient to produce, which reduces transportation emissions. Its flexibility makes it suitable for numerous applications while typically having a lower GHG footprint during production than alternatives. 

Concerns: Poor recycling infrastructure and pollution contribute to the negative perception of plastics. However, Extended Producer Responsibility (EPR) regulations could significantly improve recycling rates and reduce waste. 

• How We’re Partnering for Better Plastic Recycling: We’re proud to work with the Sustainable Packaging Coalition (SPC) to advance EPR regulations, which aim to create stronger recycling infrastructure. These measures can ensure that plastic packaging enters a circular economy instead of harming the planet. 

Paper

Strengths: Paper is lightweight, widely regarded as compostable, and often made from renewable resources. 

Concerns: Despite its reputation, paper production and recycling are energy-intensive, consuming large amounts of water and generating toxic by-products. Its GHG footprint can surpass that of plastic depending on specific applications and production methods. 

Glass

Strengths: Glass is durable and infinitely recyclable, making it favourable for closed-loop systems when collection systems are in place. 

Concerns: Glass production is highly energy-intensive, especially during the processes of melting and spraying coatings, leading to a significant carbon footprint. Additionally, the weight of glass increases transportation emissions, and the risk of breakage during shipping creates safety concerns across the supply chain. 

Aluminum

Strengths: Aluminum’s high recycling rate and lightweight nature reduce the environmental impact of transportation. Once refined, recycled aluminum requires considerably less energy than producing virgin material, making closed-loop recycling efficient and desirable. 

Concerns: The initial production of aluminum is extremely energy-intensive, generating significant GHG emissions due to smelting and refining processes. Globally, however, shifts toward renewable energy sources for aluminum production are gradually reducing its carbon footprint. 

Understanding these complexities requires evaluating materials holistically, including their environmental trade-offs and alignment with your packaging strategy. 

Actionable Insights for Driving Sustainable Packaging 

Reducing greenhouse gas emissions in packaging doesn’t have to compromise performance or aesthetics. Companies can lead the way in designing functional and eco-friendly packaging through these key strategies:

Adopt Lightweight Materials: Reducing the weight of packaging materials can dramatically lower transportation emissions. Opt for flexible packaging as a replacement for bulkier, rigid designs. 

Design for Recyclability: Use mono-materials or clearly labeled designs for easier recycling. This ensures packaging contributes to a circular system rather than ending up in a landfill. 

Explore Bio-Based Options: Bio-based plastics and renewable packaging are innovative solutions to reducing reliance on fossil fuels.

The Bottom Line on GHG and Packaging Materials 

While plastics are often criticized, they can be a surprisingly sustainable choice when GHG emissions and energy consumption are considered holistically. McKinsey’s sustainability report highlights that plastics often have a lower overall carbon footprint compared to materials like glass or aluminum, primarily due to their lightweight nature and efficient production processes. This doesn’t ignore the challenges associated with recycling rates or plastic pollution, but it does position plastics as a key player in reducing overall emissions. 

To make informed decisions, businesses must look at the bigger picture within the lifecycle of each material. By leveraging tools like our LCA Tool, organizations can identify trade-offs and select packaging solutions aligned with their sustainability goals.
