More than 480 000 people in Ile de France use an inefficient woodheating device releasing high quantities of particulate matters in the environment but do not always link air pollution and woodheating. This project aimed to inform the inhabitants about this link and encourage them to renew their ancient devices and adopt good practices around woodheating. 281 households were equiped with particulate matter sensors and the DITP compared the evolution of contamination between groups, divided in…

As rewards increasingly become an instrument used by policymakers, it is important to find a reward mechanism that does not crowd out intrinsic motivation, is long lasting, and has positive spillover effects on third parties. A policy innovation introduced by the Municipality of Santa Fe (Argentina) allowed us to evaluate different mechanisms for rewarding tax compliance – participation in a lottery (financial motive), public recognition (moral channel), and provision of a visible and durable…

In an effort to boost COVID-19 vaccination rates, mobile vaccination units were rolled out in late 2021. This strategy proved successful: the number of vaccinations administered was between 1.1 and 14.5 times higher in neighbourhoods on the days they were visited by mobile units. The units were more effective in rural areas than in urban settings. In addition, they proved to be more effective than average in neighbourhoods with a higher proportion of SGP voters and still effective, although to a…

Smart energy services and demand flexibility are increasingly important topics. Levels of awareness in an Irish context are uncertain, but engagement is low. We test different ways of framing information on engagement and intention to be flexible. We record flexibility preferences by activity and flexibility mechanisms.

Overall, this research investigated how to enhance the effectiveness of multi-stakeholder collaboration in tackling climate change. By leveraging two socio-psychological theories – Self-Affirmation Theory (SAT) and Moral Foundations Theory (MFT),this study equipped facilitators with strategies to reduce identity threats, foster constructive dialogs, and ultimately contribute to the development of more effective solutions in the environmental domain.

The project’s goal was to increase voter turnout among potential voters: registered voters who participated in one or fewer primary elections since 2000. Voting is a high-salience, socially important behavior that is essential to a functioning democratic society. While campaigns and organizations spend millions of dollars to increase voter turnout, recent research suggests that simple interventions like facilitating plan-making can help people follow through on their intentions.

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…

The Program of Applied Research on Climate Action in Canada (PARCA Canada) combines behavioural science (BeSci) insights and methods with robust policy analysis to promote climate action. One of the main areas of focus involves the launch of a longitudinal survey that will, over time, collect data on research questions of interest to the promotion of climate action in Canada (e.g. transportation, home energy use, waste management, engagement with nature, preparedness for extreme weather,…

ideas24 partnered with the Practical Farmers of Iowa (PFI) to better understand the behavioral barriers preventing corn and soybean farmers from adopting cover crops and enrolling in PFI's cover-crop cost-share program. Using what we learned from administrative data, farmer interviews and direct feedback during user-testing, we then jointly designed behaviorally informed communication interventions, which included mailers as well as a farmer referral campaign. To evaluate the potential impact of…

Every year, governments spend large amounts of resources on development programs that aim to change poor households’ behaviors and attitudes toward investment in the education, health, and nutrition of their children as a way to end the cycle of poverty. One key mechanism that can achieve this is working to raise aspirations. But how do you do that in practice? In this project, together with Karen Macours of the Paris School of Economics and the Ministry of Family in Nicaragua, we find that…
