Telling people how to save energy lowers their support for government policy on climate change, new research has found.
Lincoln University’s Dr Jorie Knook co-authored Priming for individual energy efficiency action crowds out support national climate change policy, with Zack Dorner (University of Waikato) and Philip Stahlmann-Brown (Manaaki Whenua – Landcare Research).
The study looked at the crowding out effect, which occurred when people who are encouraged to take one action for the
environment are less likely to take or support a second action.
This phenomenon is an issue if household actions, such as changing lightbulbs, reduces support for policy. National
climate policy has a much bigger potential to reduce emissions than low cost individual actions.
In the survey, half of the participants were asked to think about implementing low-cost energy efficiency measures in
their household.
All the participants were then asked about their support for a national policy intervention that reduced emissions from
fuel use that would raise the price of petrol.
The results showed a crowding-out effect from individual actions on support for national policy, with lower support
among those primed to think about energy efficiency.
The crowding out effect was strongest among those most worried about climate change.
This suggests that reminding people about individual actions they can take reduced their worry, and made them less
likely to support national policy.
Crowding out is not generally considered in the development and implementation of policies, but questions have been
raised concerning the probability that the promotion of these actions could undermine public support for more
comprehensive policy measures.
The survey was conducted among lifestyle farmers in 2019 as part of the Survey for Rural Decisions Makers, run every two
years by Manaaki Whenua. The results were consistent with other studies in other countries, meaning similar results are
likely if conducted among urban households.
The authors said the study contributed to an understanding of when and why crowding out occurs in order to help
communicate about climate change policy.
