The paper presents the understanding of and attitudes towards climate change and climate policies in Ukraine, using a survey on a representative sample of more than 1 500 Ukrainians. The survey was carried out between October 2021 and February 2022 and presents the situation before Russia’s large-scale invasion of Ukraine. The survey tests support for three main climate policies in detail: a green infrastructure programme, a carbon tax with cash transfers and a ban on combustion-engine cars. It shows that support for climate policies depends on three key factors: how people perceive the effectiveness of the policies in reducing emissions, how they perceive distributional impacts on lower-income households (inequality concerns), and if they think their household will gain or lose from the policy. The survey also shows that when citizens receive information that specifically addresses these concerns, they exhibit stronger support for the policy. How the policy is designed also matters: Ukrainians widely accept a carbon tax when its revenues finance green investments and/or compensate lower-income households. The paper highlights seven considerations for Ukraine policymakers to design measures that are effective and supported by citizens. Following Russia’s war of aggression and once conditions are right, Ukrainian policymakers can also use the survey results to guide the reform of the environmental tax system- one of the goals in Ukraine’s recovery and reform agenda. The survey in Ukraine that the paper describes was conducted as part of a large-scale OECD international survey of attitudes toward climate policies carried out on over 40 000 respondents in twenty countries.
