Unwrapping Net Zero in the Plastics Industry

The countdown to net zero is intensifying for all industries, and plastics is no exception. As manufacturers strive to meet their sustainability targets, decarbonisation, energy efficiency, and waste reduction are crucial to ensuring the plastics industry doesn’t lag behind. By 2050, the industry must fully embrace these changes to achieve net zero emissions.

The Scale of the Challenge

Plastics production has seen an explosive rise. According to Refficiency, global plastic production grew 60-fold between 1950 and 1990, far surpassing the growth of materials like steel and aluminium. This growth stems from plastics’ versatility, low cost, and durability, making them indispensable across numerous sectors. Today, plastics account for:

While plastics have become ubiquitous, their environmental footprint remains immense, and addressing this is the dual challenge of the plastics industry: reducing carbon emissions and minimising plastic waste.

Current Emissions Profile

In the UK, CO₂ emissions from plastics manufacturing have dropped from around 4.5 million metric tonnes in 1990 to roughly 3 million metric tonnes today, equating to an overall reduction of approximately 33%. This headline figure shows progress, but it doesn’t fully capture the complexity of the sector’s journey toward sustainability.

During the same period, plastics production has seen a substantial increase. In 1990, UK plastics manufacturing output was 400,000 million tonnes, which has steadily grown over the decades to reach 1.6 million tonnes. This growth is further amplified by advancements in “lightweighting”, where the same components are manufactured using less material and therefore weigh less. This means that while the total weight of output has increased, the efficiency per tonne produced has also improved – this lightweighting is not factored into the figures here as this cannot be quantified, but it’s worth bearing in mind when you consider the emissions per weight of output, or emissions intensity, where there has been significant progress.

Between 1990 and 2010, the emissions intensity of the plastics sector dropped by 77%, reflecting substantial efficiency improvements in the sector. However, the rate of reduction has slowed considerably since then, with emissions intensity in 2022 showing only a 30% reduction from the 2010 level. This suggests that while initial improvements were impactful, further gains in emissions efficiency may now be more challenging to achieve.

In addition to the pure manufacturing emissions from the sector, the plastics industry has to continue to work on the circularity of their products and innovate to reduce its environmental impact.

Industry Support and Guidance

The British Plastics Federation (BPF), representing over 80% of the UK plastics industry, is actively helping businesses reduce their environmental impact. Through their resources, they provide a roadmap to net zero, covering:

Key Challenges to Overcome

Despite available guidance, the path to net zero remains difficult. Major obstacles include:

BPF’s Role in Driving Change

The BPF’s step-by-step strategy emphasises practical steps that plastics manufacturers must follow to develop effective net zero strategies:

The Path Forward for the Plastics Industry

Though the UK plastics industry has made significant progress from 1990 to 2010, emissions reduction has become more stagnated over the last decade, and more decisive action is needed. Plastics manufacturers must focus on energy efficiency, Scope 1, 2, and 3 emissions reduction, and minimising the overall environmental impact of their products.
