Shifting to Sustainable Diets Can Cut Environmental Footprints by Up to 80%

Adopting environmentally sustainable dietary patterns, particularly those that reduce animal-based food consumption, can significantly decrease greenhouse gas emissions, land use, and water use.

01

Key Findings

  • 01Shifting to sustainable dietary patterns can lead to reductions of up to 70-80% in greenhouse gas emissions and land use, and up to 50% in water use.
  • 02Reductions in environmental footprints were generally proportional to the degree of animal-based food restriction.
  • 03Dietary shifts also showed modest benefits in reducing all-cause mortality risk.
02

Application

Design takeaway

Prioritize the development and promotion of food products and systems that facilitate reduced consumption of animal-based products to achieve substantial environmental benefits.

How to apply

Consider the lifecycle environmental impact of food products, focusing on reducing reliance on resource-intensive animal agriculture. Explore innovative solutions for plant-based food production, processing, and distribution.

Project actions

  • 01When designing food-related products or services, consider how they encourage or enable sustainable dietary choices.
  • 02Quantify the environmental impact of different food options as part of your design process.

Method & Evidence

AimWhat are the potential reductions in greenhouse gas emissions, land use, and water use achievable by shifting current dietary intakes to environmentally sustainable dietary patterns?
MethodSystematic Review
ProcedureThe researchers systematically reviewed existing evidence to quantify the environmental impacts (GHG emissions, land use, water use) associated with shifting dietary patterns towards more sustainable options, and also assessed associated health benefits.
ContextFood systems and public health

Variables

IVDietary pattern (e.g., Western diet vs. sustainable diet, level of animal-based food restriction)
DVGreenhouse gas emissions, Land use, Water use, Health outcomes (e.g., mortality risk)
CVBaseline dietary intakes, specific definitions of 'sustainable' diets across studies
04

Strengths & Limitations

Strengths

  • +Comprehensive synthesis of existing evidence.
  • +Quantifies potential environmental benefits across multiple resource indicators.

Limitations

The study is a review, so it synthesizes existing data rather than generating new primary data. The specific 'sustainable dietary patterns' can vary.

Reliability & validity

The reliability of the findings depends on the quality and consistency of the studies included in the systematic review. Validity is supported by the systematic methodology used to select and analyze studies.

Think critically

To what extent can design interventions effectively influence widespread adoption of these sustainable dietary patterns, and what are the potential socio-economic barriers?

05

Design Principles

"Resource efficiency in food systems is directly influenced by dietary choices."

This research highlights the substantial environmental impact of food systems and demonstrates that strategic dietary choices by consumers can lead to considerable resource savings. Designers and engineers working in food production, packaging, and related industries can leverage this insight to develop more sustainable products and processes.

Paragraph starter

This systematic review by Aleksandrowicz et al. (2016) demonstrates that shifting towards sustainable dietary patterns, particularly those reducing animal-based food consumption, can lead to significant reductions in greenhouse gas emissions (up to 80%), land use (up to 80%), and water use (up to 50%). This highlights the substantial environmental impact of food systems and the potential for dietary choices to drive resource efficiency, a key consideration for sustainable design projects.
