## 2 Materials and Methods
### Methodology and Sampling Parameters  
This research used quantitative methods to collect data, including demographic data, and the SPSS statistical package was used to analyze the data.  
Data were collected by using a mass questionnaire-based survey of residents in parts of the Murmansk Region and Karelian Arctic districts performed by the team of authors in the summer of 2020. The survey method was direct interviewing. Study area consistedof the following: 6 Arctic municipal districts of the Republic of Karelia and 3 cities of the Murmansk region. The survey was based on a stratified route sample with quota selection of survey units in the last step. The first step was segmentation by the level of socio-economic development of the region. The second step was the selection of respondents based on gender and age quotas representative of the structure of the total population. The sample set included permanent residents of the stated areas aged 18-72 years. An average respondent was 41.7 years old. The survey covered 1505 respondents. The gender and age structure of the sample was similar to that of the total population, featuring the following percentages (Table 1).  
The available sample is similar to the general population. There is a slight shift in the gender and age profile towards female persons. In the age aspect, the sample parameters are somewhat shifted towards younger age categories.  
The toolkit included blocks of questions to record contextual variables (age, gender, education and income); private sphere green practices (switch off the lights when leaving the room, try to combine the household needs of the family in order to save electricity and reduce the costs, etc.); non-activist public-sphere behaviors (support an NGO dealing with environmental or green energy issues financially; meet with representatives of energy companies, appeal to the authorities on green energy issues, etc.); and environmental activism (participate in nonviolent environmental activism, participate in an environmental NGO, etc.). A four-point (never; sometimes; often; and always) scale was used for most of the questions. The questionnaire used in this analysis is part of a larger questionnaire that also includes questions about the perception of current environmental problems, threats and their sources by the population.

7. I initiate weekend clean-up events, garbage collection in the common area and in the forest.
8. I buy eco-labeled products.
9. I care about reducing energy consumption.
10. I choose natural products from local producers.
11. I choose more environmentally friendly ways of transportation (biking, walking, etc.).

14. I strive to reduce my consumption of disposable household items (such as plastic cups).
