Application

Design takeaway

Actively reduce reliance on virgin fossil-fuel-based plastics by designing for circularity, material substitution with lower-impact alternatives, and advocating for sustainable production methods.

How to apply

When selecting materials for a new design project, conduct a thorough analysis of their lifecycle greenhouse gas emissions, paying particular attention to the impact of primary production. Prioritize materials with lower carbon footprints and explore options for incorporating recycled content or bio-based alternatives.

Project actions

01When choosing materials for your design project, research their environmental impact, especially how much pollution is created when they are made from scratch.
02Consider if you can use recycled materials or materials made from plants instead of new ones made from oil.

Method & Evidence

AimTo quantify the greenhouse gas emissions from global primary plastic production, disaggregated by polymer type and production technology, and assess their impact on carbon budgets for limiting global warming to 1.5°C.

MethodBottom-up modeling of greenhouse gas emissions

ProcedureThe study developed comprehensive bottom-up models to analyze greenhouse gas emissions from global primary plastic production. This included material flows, production stages, processes, and technologies across the entire value chain, from fossil fuel extraction to final product shaping. The analysis focused on nine major fossil fuel-based plastic polymers, accounting for approximately 80% of global production, and evaluated emission estimates under various growth scenarios against carbon budgets compatible with a 1.5°C global trajectory.

ContextGlobal primary plastic production and its climate impact

Variables

IVPlastic production volume, reliance on fossil fuels, production technologies, polymer types

DVGreenhouse gas emissions, contribution to carbon budget

CVGlobal average temperature rise targets (1.5°C, 2°C)

Strengths & Limitations

Strengths

+Comprehensive bottom-up modeling approach.
+Disaggregation of emissions by polymer and technology provides granular insights.

Limitations

The accuracy of the findings depends on the quality and completeness of the data used for the bottom-up modeling, and future projections are subject to change.

Reliability & validity

The reliability of the study is enhanced by its comprehensive modeling approach. Validity is supported by the focus on major plastic types and the context of established climate targets, though future projections inherently introduce some uncertainty.

Think critically

Given the significant climate impact of primary plastic production, what are the most effective strategies for designers and engineers to drive a transition towards a circular economy for plastics?

Design Principles

"Minimize the embodied carbon footprint of products by critically evaluating and reducing the use of primary fossil-fuel-derived materials."

Understanding the climate impact of primary plastic production is crucial for designers and engineers to make informed material choices and advocate for sustainable alternatives. This research highlights the urgent need to decouple plastic production from fossil fuels and explore circular economy models to mitigate climate change.

What This Means for Your Design

Making new plastics from oil and gas creates a lot of pollution that warms the planet. If we keep making plastics the way we do now, we won't be able to stop the Earth from getting too hot.
