WWF Cold Wash Lit Review_Sept 2 2022_vF

The report analyzes why consumers avoid cold water washing despite sustainability goals, identifying capability, opportunity, and motivation barriers. It proposes interventions based on the EAST (Easy, Attractive, Social, Timely) framework, such as changing machine defaults and leveraging social norms, to bridge the intention-behavior gap.

• Consumers face significant capability barriers to cold water washing, including a lack of awareness that cold water can effectively clean clothes and a lack of knowledge on how to operate machine interfaces. A P&G study indicated that 62% of infrequent cold-wash users believed "cold water does not clean as well as hot water".
• Opportunity barriers include the prevalence of warm or hot water as the machine default and a perceived social norm that this is the standard practice. The report notes that for many machines, the "'normal' setting is the warm temperature", and consumers often view cold water as being for "exceptional cases only".
• Motivation barriers are driven by habitual 'autopilot' behavior and a 'present bias' where immediate perceived losses (e.g., less clean clothes) outweigh future gains (e.g., energy and cost savings). This is exacerbated by 'loss aversion', where the fear of poor cleaning performance is weighted more heavily than the benefits of sustainability.
• Several factors enable the transition to cold water washing, most notably that it requires no new equipment or significant additional physical effort. It also aligns with existing consumer values regarding monetary savings and sustainability, and is already perceived as beneficial for "delicates, color preservation".
• Interventions to make the behavior 'Easy' are highly effective, particularly the use of defaults. A simulated study in the Netherlands found that a "default cold water setting increased cold water use" and resulted in users consuming "24% less energy".
• Making the behavior 'Attractive' can be achieved through personalized goals and salient benefit messaging. A P&G 'In Use Learning Study' using a flyer that highlighted saving money, protecting clothes, and helping the environment increased cold water cycles by "22 percentage points" for users of high-quality detergent.
• Social and Timely interventions leverage peer influence and critical decision moments. Examples include using "eco reps" in US college dorms to promote habits and using visual prompts (like stickers) to disrupt automatic habits, as seen in a UK study where food waste recycling prompts increased collection by "21%".
