Happier with less? Members of European environmental grassroots initiatives reconcile lower carbon footprints with higher life satisfaction and income increases

Abstract

Scientists and policymakers recognize the need to address consumption and lifestyles in order to reconcile environmental and development agendas. Sustainability-oriented grassroots initiatives emerge bottom-up to create opportunities for sustainable lifestyles; yet no prior assessment has ascertained the efficacy of their members to reduce carbon footprints (CF) and enhance well-being. We compare the CF of non-members and members of grassroots initiatives in the domains of food, clothing, housing and transport. We further compare the groups by testing the influence of socio-economic variables that are typically associated with both footprint and well-being. Here we show that grassroots initiative members have 16% lower total carbon footprint, and 43% and 86% lower carbon footprints for food and clothing respectively, compared to their "non-member" regional socio-demographic counterparts. We find a higher adoption of some energy-saving behaviors for initiative members such as greater active travel distance and lower indoor temperatures in the winter, yet no significant differences in the CF of housing and transport. Interestingly, increases in income are not associated with increases in the total CF of members, while the influence of income is confirmed for the CF of the total sample. Instead, factors such as age, household size, and gender better explain the variation in the domain-specific CFs of initiative members. Finally, members show higher life satisfaction compared to non-members and are 11-13% more likely to evaluate their life positively. Our results suggest that initiative members uncover lifestyle features that not only enable lower emissions, but also reconcile emissions with income and well-being.

Sustainable Financial Education and Consumer Life Satisfaction

“…Income situation is one of the most important factors affecting consumer life satisfaction in microeconomic variables. Vita et al [27] compared the various household groups by testing the influence of socio-economic variables that were typically associated with consumer life satisfaction and suggested that the positive influence of income was verified. In general, income is positively correlated with consumer life satisfaction.…”

Behavioral Influences on Crowdfunding SDG Initiatives: The Importance of Personality and Subjective Well-Being

“…People's attachment plays a crucial role in their subjective well-being in terms of sustainability initiatives [35,36], information technology [37], and adult attachment styles [38,39]. Yet, despite its significance, research on the relationship between attachment and subjective well-being has not been undertaken in SDG crowdfunding settings.…”

Mexico's 20 years of North American Free Trade Agreement: Socio-Environmental Trends and Unequal Exchange

“…Despite declining carbon intensities, we cannot conclude that the NAFTA launched Mexico towards sustainability as we only find indication of relative decoupling of decelerating growth in emissions with respect to growth in GDP. A critique of carbon intensity as indicator for decoupling is the role of ballooning financial, services, and trade -all of them relatively immaterial sectors that inflate GDP and thus make the indicator unsuitable for confirming relative decoupling [21], [22]. Moreover, the increases in eco-efficiency are typically overwhelmed by the total volume increase in footprints i.e.…”
