Public expectations about the impact of COVID-19 on climate action by citizens and government.

Since the onset of the COVID-19 crisis many have opinionated on how it may affect society's response to climate change. Two key questions here are how COVID-19 is expected to influence climate action by citizens and by the government. We answer these by applying topic modelling to textual responses from a survey of Spanish citizens.

Climate concern and policy acceptance before and after COVID-19.

It remains unclear how COVID-19 has affected public engagement with the climate crisis. According to the finite-pool-of-worry hypothesis, concern about climate change should have decreased after the pandemic, in turn reducing climate-policy acceptance. Here we test these and several other conjectures by using survey data from 1172 Spanish participants who responded before and after the first wave of COVID-19, allowing for both aggregate and within-person analyses.

Carbon tax acceptability with information provision and mixed revenue uses.

Public acceptability of carbon taxation depends on its revenue use. Which single or mixed revenue use is most appropriate, and which perceptions of policy effectiveness and fairness explain this, remains unclear. It is, moreover, uncertain how people's prior knowledge about carbon taxation affects policy acceptability.

Tackling the plastic problem: A review on perceptions, behaviors, and interventions.

The excessive production and consumption of plastic has serious consequences on the environment and human health. The reduction of plastic has therefore become a major global challenge. As technical solutions might be insufficient to curb the problem, a perspective highlighting the impact of human behavior is needed.
