This online experiment tested various ways in which sustainability measures for homeowners are presented on the website verbeterjehuis.nl, ‘improve your home’. The variant emphasising that the sustainability measures are 'recommended for your personal situation' proved to be most effective. This addition acts as an incentive to homeowners to install roof insulation or adopt other sustainability measures. Why this experiment was conducted: verbeterjehuis.nl website optimisation Homeowners…

A series of controlled randomised experiments was conducted to examine the savings effects for households of three types of energy consumption managers tools: an email + web application, an app installed on a smartphone or tablet and an in-home display. Energy savings could only be established for the in-home display: almost 7% on natural gas and over 2% on electricity consumption. Why this experiment was conducted: The Netherlands' climate targets Energy consumption by Dutch households…

Rijkswaterstaat (the Directorate-General for Public Works and Water Management) wants to induce behavioural change in several areas. The circular economy is one example. A study examined whether consumers will make more sustainable choices if they have been complimented on their past actions or behaviour that were environmentally friendly or sustainable. This proved to be the case. Why this experiment was conducted: additional incentive for sustainable behaviour Behavioural change is…

Why this experiment was conducted: scepticism about second-hand clothes The clothing industry is a major polluter, and the second-hand market is an important alternative to new clothes. While more and more Dutch consumers are turning to pre-owned clothing, a large group remains sceptical. According to a target group study conducted in 2020, they wonder whether they will be able to find a suitable second-hand item, and whether it is hygienic. The best way to overcome this scepticism is to create…

Using sustainable transportation alternatives can often be hindered by car dependence (Haustein, 2021). Within the context of Santa Monica, for example, approximately 75% of Santa Monica residents choose single occupancy vehicle (SOV) commutes to work, and over 50% of households own more than one vehicle (Data USA, n.d.). More generally, vehicle transportation accounts for 62% of greenhouse gas emissions in the city, making it the largest emissions contributor (Johnstone, 2021). However,…

Behavioural science in the context of climate change at its related health risks has mainly focused on understanding and changing individual behaviours. However, effectively addressing the climate crisis requires broadening the focus on systemic societal change. This level of change is required to mitigate the negative effects of climate change as well as help people adapt to the associated (health) risks. Fostering systemic societal change requires situation-specific, large-scale data that can…

Landfills are a major contributor to methane emissions in the United States. By diverting organic waste from landfills, composting may reduce the global warming effects caused by methane. However, only a small proportion of compostable food is currently composted. This is because of barriers to composting that are both structural (lack of public composting infrastructure) and psychological (insufficient knowledge about and interest in composting among prospective users). We set out to develop a…

Avoiding electrical waste and promoting the manufacture of and demand for sustainable electrical products are key goals for the Federal Government. To this end, transparency for consumers is to be improved. Whether a lifespan label for electrical products can help achieve this aim was tested in an empirical study. The findings show that a lifespan label would lead to 3 out of 100 consumers opting for a more expensive product with a longer lifespan. When the lifespan was combined with information…

The Environmental Habits and Values Survey (2020) aims to explore the values, opinions, attitudes and behaviour of Barcelona's citizens in relation to the environment, sustainability and climate change. This study was launched in 2000 and is carried out every four years. This year, 2024, the questions have been revised and the project is on-going. The series has a dual value: on the one hand, it provides a snapshot of the values and attitudes of Barcelona residents at the time the survey is…
