1. Introduction
The influences on Earth by mankind have become stronger in the last few centuries. Humans are moving further from sustainability than ever before in history [
1,
2]. About 74% of the observed global warming is due to human activity [
3]. Thus, human-incurred changes occur more quickly than do natural planetary changes. Due to this shift, a new geological era has started [
4]. The era of the Anthropocene is based on the effect that is caused together with population growth and mainstreaming mass consumption [
5]. Sustainable living is an imperative in the era of the Anthropocene because the power of humans is now stronger than ever.
Every extensive challenge of the future has ecological and social backgrounds. All materials needed by humankind are taken from nature and returned to nature [
6]. Your life and mine are fully dependent on the biosphere: clean air, fresh water and food [
7]. Hence, there is a hierarchy that states that humans cannot exist without nature, and without a society, there cannot be economy [
8,
9].
In the era of the Anthropocene, climate change is the greatest threat to mankind [
10,
11,
12,
13,
14]. Warming continued in 2016, setting a new temperature record approximately 1.1 °C above the pre-industrial period and 0.06 °C above the previous highest value set in 2015. Carbon dioxide (CO
2) reached new highs at 400.0 ± 0.1 ppm in the atmosphere at the end of 2015. The extent of global sea-ice dropped more than 4 million km
2 below average. Globally-averaged surface mole fractions for CO
2, methane (CH4) and nitrous oxide (N
2O) reached new highs in 2015, with CO
2 at 400.0 ± 0.1 ppm, CH4 at 1 845 ± 2 parts per billion (ppb) and N
2O at 328.0 ± 0.1 ppb. These values constitute, respectively, 144%, 256% and 121% of pre-industrial (before 1750) levels [
15]. The global land and ocean temperature for September 2017 was 0.78 °C higher than the 20th century average of 15.0 °C. This was the fourth highest September temperature on record for the globe since records began in 1880. The 10 warmest Septembers have occurred during the 21st Century, specifically since 2003 [
16].
Fifteen thousand three hundred sixty four scientists from 184 countries argue that the reduction of carbon emissions is needed rapidly to protect young people, future generations and nature [
17]. Transforming lifestyles and societies is not easy. However, there are many promising examples of good progress in our history, such as longer life spans and decreasing mortality in under-five-year-old children. It is also evident that basic education is now available in almost every country [
18,
19]. In 2002, the United Nations summit on sustainable development stated the remarkable ecological and social disadvantages of lead in gasoline in Sub-Saharan Africa. Oil companies took up the gauntlet. In four years, leaded gasoline disappeared from the market [
20]. A successful and promising example of human power is also putting an end to ozone depletion. In 1985, the world took the first significant step in Vienna. A common threat to all life on Earth was recognized, and the necessary steps for prevention were taken straight away. Currently, ozone depletion is not a threat to life on Earth [
21]. Four decisive steps are typical for systemic changes in societies: (a) scientific consensus of the threat, (b) enlightening people about the threat, (c) developing alternative technological solutions and (d) effective international cooperation [
22].
Several studies show that most people respond positively, but passively, to the increasing need of a sustainable way of living in their everyday lives [
23,
24,
25,
26]. In Finland, the standard way of life today is far from sustainable. If everyone on Earth consumed like the average Finnish citizen, four Earths would be needed in order to fulfil humans’ material needs. The average carbon footprint in a Finnish household is 10 tonnes of CO
2. The sustainable carbon footprint is less than 2.5 tonnes [
27,
28]. Housing accounts for 30% (three tonnes), consumption and waste for 31% (3.1 tonnes), transportation and mobility for 21% (2.1 tonnes) and food for 17% (1.7 tonnes) [
29]. Finland has the highest ecological footprint of the Nordic countries (total global hectares per capita 6.7) [
30], and the carbon dioxide emissions of Finnish consumption are the ninth highest in the world [
31].
It is promising that the majority of 15–29-year-old Finnish people (78%) express the opinion that they would act pro-environmentally even when others do not [
32]. Seventy two percent agrees that striving for continuous economic growth will ultimately lead to the destruction of nature and human life [
33]. However, Finns share the worldwide problem of being “unmoved”: the majority acknowledge that climate change is a serious problem caused by humans, but still personally continue to overconsume [
34]. Thus, it seems that radical behavioral changes are required.
The purpose of this work is to research sustainable living in a Finn’s everyday life. We analyze sustainable living in the context of minimizing direct and indirect influences on climate change. We are not interested in knowing the attitudes or values of citizens, but the real implementation of sustainability in daily life. What we do is focus on the Finnish population in a holistic way, that is without demographics. Our specific research questions are
- (a)
How does sustainable living materialize among Finnish people?
- (b)
What is the general structure of a sustainable lifestyle in Finland?
- (c)
How do people argue their everyday behavior choices and decisions in the context of sustainability?
2. Categories of Sustainable Living
The features of a sustainable and desirable future can be relatively similar despite people’s age, education, vocation or cultural background. Most people in the world think that, for instance, increasing congestion is not the right course of development, but instead increasing healthy years of life is an example of a desirable future we want to have. Typically, long life expectancy is linked with well-being. A challenge is, however, that people tend to overestimate the life satisfaction they derive from money and material possessions. They also underestimate the benefits from more time spent with family and friends [
18]. Thus, a long, healthy and happy life is achievable in societies where the carbon dioxide equivalent is remarkably small compared to the affluent societies [
35]. The main challenge is here: achieving any given global temperature stabilization requires even steeper greenhouse gas emission reductions than previously calculated [
36].
Typically, four main categories for transitioning to a sustainable society can be identified. The categories are: sustainable food and agriculture, sustainable housing and energy, sustainable consumption and sustainable mobility [
37].
Sustainable food and agriculture: Food production and consumption are the most important contributors to global warming in Europe. The share is greater than the climate change effect caused by housing and transport [
38,
39]. In Finland, food choices constitute one sixth of the average Finnish carbon footprint [
29].
Globally, livestock accounts for up to 18% of the global warming effect [
40]. Crops are mostly used for animal feed instead of feeding humans [
41]. Beef is estimated to be ten-times more carbon intensive than fish and three-times more than pork or chicken [
27,
42]. A standard meat-based diet in Finland produces 1.5 tonnes of CO
2, a vegetarian diet 0.9 tonnes and a vegan diet 0.5 tonnes. A high meat diet is estimated to be four-times more emission intensive than a vegan diet [
29].
In Finland, a vegan diet would reduce agricultural emissions by 48% and overall food system emissions by 34% compared to the average Finnish diet [
43]. However, meat consumption has increased by 24% between 1966 and 2006 in Finland. At the same time, milk consumption has halved, and carbon-intensive cheese consumption has more than tripled (+348%) [
44]. As a result of reducing the fraction of animal-sourced foods in human diets, dual ecological and health benefits can be reached [
45]. There are promising signs of a change in ecological consumer behavior. The market in organic agricultural products grew in Finland by around 24% in 2012 [
46]. A transition to socially-fairer production and consumption habits is indicated by the fact that in 2012, fair trade grew globally by 21% and in Finland by 48%. In Switzerland, the market share of fair trade bananas has been 55–60% in recent years [
47].
Globally, 30–50% of all food produced ends up as food waste [
48]. Avoiding food waste has a multiple times more significant effect on emissions than avoiding food packaging [
27]. An average Finn produces 23 kg of food waste per year [
49].
Sustainable housing and energy: Housing and energy constitute nearly a third of the average Finnish carbon footprint. The majority (75%) of these emissions accounts for heating energy, of which one third is used for water heating [
29]. Heated living area has greatly increased because the average living space per person has more than doubled (+113%) between 1970 and 2016 [
50]. On the other hand, the energy use for household lighting in Finland decreased by almost a third (30%) between 2010 and 2015. The energy use by household appliances has also decreased by 13% [
51]. The growth in the cleantech sector, which focuses on energy and material efficiency, was approximately 30% in 2013 [
52]. Unfortunately, energy upgrades may cause a rebound effect: an estimated 5–15% of emissions saved by energy efficiency improvements are spent elsewhere, causing carbon emissions [
53].
Sustainable consumption: Consumption of goods and services including waste management is responsible for a third (31%) of the average Finnish carbon footprint. An average Finn produces 330 kg of household waste per year [
29]. The recycle rate of household waste is 41%; this is below the average level (45%) in the EU [
54]. Still, recycling is among the first examples of a sustainable lifestyle in Finland. In 2006, one in three Finnish households sorted cardboard packaging, but in 2012, 61% of households made efforts to ensure that cardboard packaging could be recycled [
55]. In the context of climate change, however, the effect of recycling is rather small, only 2% [
29]. Moreover, environmental aspects of consumption are still mostly inferior compared to experienced fluency and comfort together with personal and family well-being at all income levels [
56].
Sustainable mobility: Mobility and transportation constitute a fifth of the average Finnish carbon footprint [
29]. An average Finn uses a car for 32 km a day; this amounts to 12,000 km per year with 1.7 passengers on board on average. Public transportation travel has halved in Finland between 1974 (15%) and 2011 (8%). [
57,
58]. Car travel and holidays abroad have become the norm in Finnish society. High-carbon overnight leisure travel abroad has almost doubled (+98%) among Finns between 2005 and 2015 [
59]. In contrast, low-carbon trips by walking and cycling have decreased 5% between 2005 and 2011 [
57]. There is local variation in sustainable living. For example, use of public transportation has increased by 28% in Espoo during 2005–2015 [
60]. However, the mobility trend in Finland is still in general increasingly carbon-intensive.
There is a promising global trend in transport and mobility. Especially in cities, people are more often moving from ownership of cars to use of mobility services. Vehicles are replaced by access of seamless collective mobility services such as public transport. In Stockholm, Sweden, only one in ten 18-year-olds obtains a driving license [
61]. This trend is also identified in Helsinki, Finland [
62].
3. Materials and Methods
The data were collected by questionnaire in April 2017. The questionnaire was pretested and the propositions improved in accordance with feedback. A sample (n = 2052) was corrected by sex, age and residential area to correspond to the population of Finland. Therefore, the sample of 1030 woman and 1022 men represented the population of Finland (18–79 years old). Respondents were asked to respond to 46 propositions about the sustainable way of life. The response pattern followed a 5-point Likert scale (1 = totally disagree, 5 = totally agree) and open questions.
We applied mixed methods. A principal axis factoring was conducted on the 46 variables. Consistency of the measure was maximized by deleting variables that improved overall reliability. We ended up with 32 variables with orthogonal rotation (varimax). The Kaiser–Meyer–Olkin measure verified the sampling adequacy for the analysis (KMO = 0.96), which is well above the acceptable limit [
63]. Bartlett’s test of sphericity, χ
2 (496) = 22,304.2,
p < 0.000, indicated that correlations between variables were sufficiently large for principal axis factoring. With the correlation matrix, we verified that the correlations were not too strong (>0.8), so that the multicollinearity would prevent presenting results [
64]. The lowest loading included in the analysis was 0.38, which surpassed the limit of 0.32 defined by Tabachnik and Fidel [
65].
The respondents were able to explain why they considered the specific proposition to be important for them. After the principal axis factoring, we classified 2811 written reasonings. By classifying these open questions, it was possible to get complementary information to be added to the quantitative analysis. The most emphasized variable from each factor was analyzed by qualitative analysis using point rating. Thus, our qualitative analysis contained quantitative examination [
66]. Counting the frequencies of these qualitative themes does not reduce the “qualitativity” of analysis, but brings another dimension [
67]. The answer written as an open question for different variables of sustainable living was analyzed by the crucial proposition of the respondent. The general viewpoints were termed based on how they best described the propositions made by the respondents. The viewpoints (reasons) made from each variable can be seen as a general concept [
68].
5. Discussion
This research was a holistic and horizontal view of sustainable living in Finland. We did not focus on demographics. Instead, we were interested to know on a general level how sustainable living materializes among Finnish people, what was the structure of sustainable lifestyle in Finland and how did people argue their everyday behavior choices and decisions in the context of sustainability in order to combat climate change. These questions are current because Finland aims to be a carbon-neutral society by the year 2050; some Finnish cities, such as the City of Espoo, already by 2030. Key measures to reach carbon-neutrality are to improve energy efficiency, increase the share of renewable energy sources in a sustainable way, produce and export climate-friendly products and services and develop the low-carbon sectors of the economy [
71]. This means a fundamental change in citizens’ way of living due to the fact that households are the last gatekeepers for 72% of the global greenhouse gas (GHG) emissions at the end of the pipeline [
72,
73]. The role of household consumption is, however, often overlooked [
37]. If public engagement is in such a way considered as trivial socio-culturally when combating climate change, this means that one powerful potential for climate leadership and direct impact on collective carbon reduction is lost and immobilized.
According to our results, the structure of sustainable lifestyle has six elements: conscious citizenship, awareness of origin of materials, awareness of sustainable energy solutions, circulation and preventing loss of materials, smart mobility and sustainable food. Holistic approaches to sustainable living need to be extensively adopted and socio-culturally encouraged to strengthen the needed progress from the thin and scattered sustainability today towards the systematic and solid sustainable living of tomorrow. According to our results, a holistic approach to sustainable living starts by focusing more on conscious citizenship, which explained most of variance of the data. The most important items of conscious citizenship were requesting pro-environmental products on the market and choosing a pro-climate meal at a restaurant. Rotated factor loadings of these items were strong (
Table 1), but the implementation of the items was weak (
Figure 1).
What Finns already do is recycling. It has been automated, so that it is part of a Finn’s everyday routine and habits. However, the meaning of recycling is generally overemphasized. It is treated as the main category of sustainable living even if it has rather small importance in the carbon reduction of households [
29]. This embodies a problem of weak sustainability: recycling waste is not connected adequately to the overall picture explaining the gravity, that is the importance of a particular sector of sustainable living. This result is similar to prior research [
68].
Smart, carbon-free mobility is a challenge for Finns. In practical terms, this means how to travel from Point A to Point B. Despite a trend of shifting from cars to public transport and mobility services, Finns seem to estimate that their personal car use is at the proper level. On the other hand, even one fifth (21%) reported consideration of environmental effects when planning holidays. In the context of behavioral change, it is interesting that temporary forced use of public transport may result in permanent private car reduction [
74]. This raises a question of smart regulation in order to ensure a sustainable future for all.
Climate change and the very much needed lifestyle changes might involve difficult emotions such as grief, anxiety, fear, guilt, helplessness and loss [
75]. To meet the challenge of this potential psychological cost of a new way of living, several value perspectives could be utilized (e.g., health and well-being, effectiveness, convenience). Finns seem to be practical, so that they simultaneously save money and combat climate change by reducing waste and applying smart technology. According to our results, Finns favor domestic food and products, and they are interested in the origin of materials. Therefore, multiple benefits of sustainable living are apparent. Finns support the local economy and ensure a good employment rate for the state. For example, locally produced organic vegetables benefit the local community; food and nutrition promote public health and animal well-being; and consumer choice maintains biodiversity and helps establish global food security [
76]. Moreover, favoring domestic food and products combats climate change by reducing the carbon footprint of logistics [
42].
There are many good signals for more sustainable life in Finland. Awareness of sustainable energy solutions is good. Energy consumption of household lighting has decreased radically, and new housing must meet nearly zero-energy building criteria from 2020. Renewable energy is generally seen as positive and appealing for many, as well as avoiding energy waste. Moreover, the majority of Finnish businesses see carbon neutrality as a source of strategic competitive ability. Carbon neutrality brings global cleantech opportunities in transportation, energy systems, sustainable buildings, industrial processes and water and waste management [
77]. According to the National Energy and Climate Strategy of Finland, traffic emissions will be reduced by 50% by 2030 (compared to the 2005 level), and total greenhouse gas emissions will systematically set the course for achieving an 80–95% reduction by 2050 [
78].
On the level of materialized sustainability, Finns have, however, still so far been moving further away from sustainability instead of moving towards it in total. This embodies a challenge of thin and scattered sustainability, as well as constitutes a demand and need for a more holistic approach to behavioral change. Thus, the role of formal and non-formal education is essential when changing values and attitudes of citizens towards a more sustainable way of living. This also raises a challenge for teacher training. However, most of the barriers to sustainability-promoting daily life are contextual barriers in a society. This is the reason why smart regulation is very much needed. It is a much faster way toward sustainable society than the interventions for changing citizens’ values and attitudes by education [
79].
