How do climate policy effects scale from individual decisions to societal change? Our latest work combines behavioural experiments and agent-based modelling to address exactly this question. We're happy to see this work out in @natenergy.nature.com (check it out, it's open access): 👇

[As promised some details on our new preprint] What happens when people freely choose information about climate policies? For 4 climate food policies, participants from 15 countries from the Global South and North sampled arguments: either for or against the policy, or unrelated trivia.

People agree which climate advocating messages they like best. Good climate communication can be powerful. This is the bottom line of our new publication: doi.org/10.1016/j.je...

📯 New Preprint out 📣 Honestly, this started out as a side project that I had put on the back burner for a while. Then, I realized I could combine the original data with the data from our climate (dis)information sampling study, and found quite unexpected and cool results: doi.org/10.21203/rs....

2️⃣ Understanding these factors is key to designing interventions that actually work. We discuss the most effective interventions—psychological or structural—for targeting the psychological and contextual determinants. (3/4)

❗ Even though the focus of this framework lies on the individual's self-control process, the authors stress that nudging can only be a complementary strategy to larger systemic changes in mitigating climate change. (5/6)

3️⃣ Derive hypotheses on the main intervention effects and moderating effects of self-control components, 4️⃣ Show how nudges, nudging plus, and boosts might affect similar self-control processes, and 5️⃣ Call for more targeted, theory-driven, and scalable behavior change interventions. (4/6)

By integrating choice architecture literature with self-control theory, they: 1️⃣ Contribute to understanding when and why interventions work (or don’t), 2️⃣ Propose six key psychological mechanisms of influence, (3/6)

PSCA Joint Research Group @psbclab.bsky.social · 15/05/2025

The paper provides a novel perspective on how nudges work. They argue that the effectiveness of choice architecture interventions might lie in their influence on self-control processes—including desire inhibition, goal activation, control motivation & capacity, & behavioral feasibility. (2/6)

The results underscore the need for tailored policy mixes that ensure a balanced and equitable energy transition. These insights can help policymakers design effective policy mixes that drive the widespread adoption of low-carbon technologies and reduce the consumers' environmental impact. (6/7)

PSCA Joint Research Group @psbclab.bsky.social · 10/02/2025

For example, while subsidies can effectively promote solar panel adoption, their impact increases significantly when combined with complementary policies such as neighborhood batteries and tenant support. (5/7)

100

PSCA Joint Research Group @psbclab.bsky.social · 10/02/2025

The findings reveal that policy interventions, such as subsidies, environmental standards, and support for tenants, are critical for advancing the energy transition at the household level. Importantly, the study shows that stimulating adoption and co-adoption requires tailored policy mixes. (4/7)

PSCA Joint Research Group @psbclab.bsky.social · 10/02/2025

Unlike previous models that have focused on individual technologies and policies, this model explores how consumers adopt multiple technologies and how various policy mixes influence these decisions. (3/7)

And how can policymakers encourage the co-adoption of these technologies? Mart van der Kam, Maria Lagomarsino, Elie Azar, Ulf Hahnel, and David Parra present an agent-based model simulating consumer decisions about adopting these technologies based on data from 1,469 Swiss respondents. (2/7)

Combining solar panels with electric vehicles and heat pumps offers benefits for households by enabling the use of clean energy for transportation and home heating and for grid stability by balancing local energy demand and supply. But do households actually want to adopt this combination? (1/7)
