Received 31 March 2024; Revised 02 August 2024; Accepted 10 August 2024; Published 01 September 2024 Abstract Climate change is an important issue that countries worldwide are aware of and campaign to reduce. All parties must cooperate, whether the government, the private sector, individuals, etc. Many perception surveys have met the public's understanding and knowledge about climate change. Despite the odds, previous research supported environmental protection and sustainability in surveys, polls, and past research. However, the existing literary gap between intentions and actions and awareness and implementation has recently widened. The objectives of this research include comparing perceptions and climate change mitigation actions between Eastern and Western European countries because both regions are different, as well as searching for and comparing perceptions influencing climate change mitigation actions between them. The research adopts a quantitative methodology, emphasizing exploring secondary data from the European Investment Bank (EIB) climate change survey 2022–2023. It analyzed the data to compare the perceptions and actions of the two regions in mitigating climate change. The statistical tests included a t-test and stepwise multiple regression analysis to predict the influence of perceptions and actions on reducing climate change. The results showed that respondents' perceptions of climate change in Eastern and Western Europe were not significantly different. However, there was a significant difference in the number of reduction actions taken by Western Europeans compared to Eastern Europeans. Perceptions of climate change catastrophes and serious government mitigation actions positively influenced actions in Eastern Europe. This study found that businesses' attention to mitigation and their perception of the catastrophic effects of climate change positively influence mitigation actions in Western Europe. The recommendations guided governments, policymakers, and businesses to take action to reduce climate change, motivating people's adequate perceptions and actions. Stakeholders communicating climate change's impacts on catastrophe should present true information with honesty and transparency. Keywords: Comparative; Perceptions on Climate Change; Actions on Climate Change; Eastern and Western Europeans. 1. Introduction Climate change is a complex problem involving temperature and weather changes over extended periods. While some of these changes occur naturally, human activities have accelerated the process, mainly by burning fossil fuels such as coal, petroleum, and gas. Burning these fuels releases harmful greenhouse gases, like carbon dioxide and methane, into the atmosphere. Unfortunately, these gases trap heat from the sun, leading to an increase in global temperatures. * Corresponding author: ksomjint@wu.ac.th http://dx.doi.org/10. 28991/HEF-2024-05-03-03 ➢ This is an open access article under the CC-BY license (https://creativecommons.org/licenses/by/4.0/). © Authors retain all copyrights.
