Bridging the climate mitigation gap with economy-wide material productivity

Area of Science:

• Environmental Science
• Economics
• Climate Policy

Background:

• UK climate targets are at risk due to a projected shortfall in current policies.
• Industrial greenhouse gas emissions are rising, driven by material and product demand, outpacing carbon intensity improvements.

Purpose of the Study:

• To analyze the potential of material productivity and lifestyle changes in bridging the UK's emissions mitigation gap.
• To assess the additional effort needed for transformative change aligned with 1.5°C and 2°C temperature targets.

Main Methods:

• Integration of an input-output framework with econometric analysis.
• Inclusion of case study evidence to evaluate material productivity measures.
• Quantification of emissions savings from proposed interventions.

Main Results:

• Emissions savings from material productivity measures are comparable to the UK Government's planned climate policies.
• Material productivity enhancements could reduce the UK's anticipated emissions deficit by up to 73%.
• Lifestyle changes also contribute to bridging the mitigation gap, though their economy-wide impact is understudied.

Conclusions:

• Material productivity presents a significant, understudied opportunity for climate policy in the UK.
• Policy interventions focusing on material productivity can substantially contribute to meeting national and international climate targets.
• A greater consideration of material productivity is essential for effective climate change mitigation strategies.
