https://doi.org/10.3886/ICPSR36368.v2
The National Surveys on Energy and Environment (NSEE)was "an on-going biannual national opinion survey on energy and climate policy. Launched in 2008, over time the NSEE has covered topics such as public policy approaches to address climate change including federal, state, and international action; energy policies such as cap-and-trade, carbon taxes, renewable energy requirements, vehicle emissions standards, and many more; and knowledge and attitudes about global warming, climate adaptation, fracking, and geoengineering." The data available here include "data from eighteen waves, from Fall 2008 through Fall 2017. Demographic variables include age, years of education completed, income, political affiliation, religious affiliation, gender, and race." Data from individual waves are also available via openICPSR and via the Roper Center for Public Opinion Research. If you need to access the ICPSR and its data from off of campus, please see this notice and these instructions from the ICPSR.
Quality of Government (QOG) Institute
https://www.gu.se/en/quality-government
The QOG Institute is hosted by members of the Department of Political Science at Göteborg University in Sweden and is devoted to "the causes, consequences and nature of 'good governance.'" The Institute has created multiple collections of data on governance: a broad collection of governance indicators that is global in coverage; a more narrow collection that focuses on social policy in wealthier countries; data from expert surveys on politicization and professionalization of public administration in individual countries, and a new data collection on perceptions of corruption in individual regions within EU members. The data are compiled from multiple sources, including the Polity Project, the Cingarelli-Richards Human Rights Data, Transparency International, Freedom House, various international organizations, and datasets produced by various academics. The QoG data are available in SPSS, Stata, and comma-delimited (.csv) formats.

The World Bank hosts a website devoted to research on governance and institutional quality and their relevance for economic development and performance. As part of its efforts in this area, the Bank collects and distributes data on a variety of aspects of governance and institutional quality. Of particular interest may be the Worldwide Governance Indicators, which score countries in areas such as control of corruption and regulatory quality, and the firm-level surveys such as the Enterprise Surveys. The Bank's Prosperity Data360 site also brings together hundreds of governance-related indicators from multiple data sources and makes them available via tools for downloading and visualization.

The Yale Program on Climate Change Communication conducts "scientific research on public climate change knowledge, attitudes, policy preferences, and behavior, and the underlying psychological, cultural, and political factors that influence them." As part of its work, the Center has created multiple tools and interactive sites for summarizing and visualizing data that it collects. The data are available to download upon request. Some of the Center's data are also available via the Open Science Foundation at https://osf.io/. The data mainly focus on the United States, including some state-level data, but there are also data and maps for Canada and India.
