Low-Carbon Lifestyles beyond Decarbonisation: Toward a More Creative Use of the Carbon Footprinting Method

Sustainability

There is a growing recognition of the urgent need to change citizens’ lifestyles to realise decarbonised societies. Consumption-based accounting (carbon footprinting) is a helpful indicator for measuring the impacts of peoples’ consumption on climate change by capturing both direct and embedded carbon emissions. However, while carbon footprinting can propose impactful behaviour changes to reduce carbon footprints immediately, it may deflect people’s attention from the much needed but time-consuming efforts to reshape the “systems of provisions” to enable decarbonised living. To propose a more constructive application of carbon footprinting, the paper examines the three cases of using carbon footprinting derived from the 1.5-degree lifestyles project, including citizens’ discussions and experiments in six cities in 2020 and 2021, citizens’ workshops contributing to the local policy development in 2022, and lectures and mini-workshops since 2020. Based on the examination of the cases,...

Lifestyle carbon footprints and changes in lifestyles to limit global warming to 1.5 °C, and ways forward for related research

Sustainability Science

This paper presents an approach for assessing lifestyle carbon footprints and lifestyle change options aimed at achieving the 1.5 °C climate goal and facilitating the transition to decarbonized lifestyles through stakeholder participatory research. Using data on Finland and Japan it shows potential impacts of reducing carbon footprints through changes in lifestyles for around 30 options covering food, housing, and mobility domains, in comparison with the 2030 and 2050 per-capita targets (2.5–3.2 tCO2e by 2030; 0.7–1.4 tCO2e by 2050). It discusses research opportunities for expanding the footprint-based quantitative analysis to incorporate subnational analysis, living lab, and scenario development aiming at advancing sustainability science on the transition to decarbonized lifestyles.

Current lifestyles in the context of future climate targets: analysis of long-term scenarios and consumer segments for residential and transport

Environmental Research Communications

The carbon emissions of individuals strongly depend on their lifestyle, both between and within regions. Therefore, lifestyle changes could have a significant potential for climate change mitigation. This potential is not fully explored in long-term scenarios, as the representation of behaviour change and consumer heterogeneity in these scenarios is limited. We explore the impact and feasibility of lifestyle and behaviour changes in achieving climate targets by analysing current per-capita emissions of transport and residential sectors for different regions and consumer segments within one of the regions, namely Japan. We compare these static snapshots to changes in per-capita emissions from consumption and technology changes in long-term mitigation scenarios. The analysis shows less need for reliance on technological solutions if consumption patterns become more sustainable. Furthermore, a large share of Japanese consumers is characterised by consumption patterns consistent with th...

Green Living: Reducing the Individual's Carbon Footprint

The present chapter is a companion piece to chapter 6, "Climate Change and Health," which covers the health-related implications of climate change. It examines general considerations regarding the components of people's carbon footprints (the levels of per capita emissions of C02 and other greenhouse gases) and individual actions such as ethical consumption in order to reduce the production of greenhouse gases; the chapter also provides examples of best practices for reducing carbon emissions by individuals and households well as by the various levels of government.

Help the climate, change your diet: A cross-sectional study on how to involve consumers in a transition to a low-carbon society

This paper explores how the transition to a low-carbon society to mitigate climate change can be better supported by a diet change. As climate mitigation is not the focal goal of consumers who are buying or consuming food, the study highlighted the role of motivational and cognitive background factors, including possible spillover effects. Consumer samples in the Netherlands (n ¼ 527) and the United States (n ¼ 556) were asked to evaluate food-related and energy-related mitigation options in a design that included three food-related options with very different mitigation potentials (i.e. eating less meat, buying local and seasonal food, and buying organic food). They rated each option's effectiveness and their willingness to adopt it. The outstanding effectiveness of the less meat option (as established by climate experts) was recognized by merely 12% of the Dutch and 6% of the American sample. Many more participants gave fairly positive effectiveness ratings and this was correlated with belief in human causation of climate change, personal importance of climate change, and being a moderate meat eater. Willingness to adopt the less meat option increased with its perceived effectiveness and, controlling for that, it was significantly related to various motivationally relevant factors. The local food option appealed to consumer segments with overlapping but partly different motivational orientations. It was concluded that a transition to a low carbon society can significantly benefit from a special focus on the food-related options to involve more consumers and to improve mitigation.

Multi-Criteria Assessment of Household Preferences for Reducing Greenhouse Gas Emissions: An Analysis of Household Survey Data from Four European Cities

2018

n=190) In a study of households living in mid-size cities in France, Germany, Norway and Sweden we assessed preferences (among 65 possible actions) for reducing greenhouse gas (GHG) emissions. Each GHG reduction action was compared in terms of three objective criteria – CO2e emissions, health impact and cost – using scores which gave alternative priority weightings to each. The multi-criteria scores were then compared with the proportion of respondents declaring their willingness to implement each action. Actions that respondents were often willing to implement and scored highly on the three assessment criteria included measures with likely ancillary benefits for health such as eating 30% more vegetarian food, walking and cycling instead of using public transport, and improvements of roof and window insulation. Although most householders appeared willing to make appreciable changes to their lifestyle and home in order to help achieve GHG emissions reductions, relatively few signaled...

Lifestyle Changes: Significant Contribution to GHG Emission Reduction Efforts

Climate Change Management, 2010

The EU initiated a campaign “You control climate change”, which was launched in summer 2006. The campaign used TV, outdoor, and newspaper advertising, as well as a range of electronic tools, such as banners and emailings, to attract attention. There was a school student element as well – the Europa Diary for 2007–2008, with more than 2.3 million copies distributed throughout Europe, included a section on climate change and encouraged students to reduce their personal greenhouse gas emissions by making small changes to their daily behaviour. Based on this idea, the goal was set to analyse the possibilities to reduce GHG emissions in our everyday life based on experiments carried out by the students at Vilnius University Kaunas Faculty of Humanities. The aim of the experiment was to calculate GHG emission reduction by one household during the year by changing life habits towards sustainable consumption and recording this daily. The Carbon Calculator available on the website developed by the EU campaign “You control climate change” was used to calculate how many kg of CO2 can be saved each year by adopting lifestyle changes. The results of the exercise are described in this chapter.

It starts at home? Climate policies targeting household consumption and behavioral decisions are key to low-carbon futures

Through their consumption behavior, households are responsible for 72% of global greenhouse gas emissions. Thus, they are key actors in reaching the 1.5 °C goal under the Paris Agreement. However, the possible contribution and position of households in climate policies is neither well understood, nor do households receive sufficiently high priority in current climate policy strategies. This paper investigates how behavioral change can achieve a substantial reduction in greenhouse gas emissions in European high-income countries. It uses theoretical thinking and some core results from the HOPE research project, which investigated household preferences for reducing emissions in four European cities in France, Germany, Norway and Sweden. The paper makes five major points: First, car and plane mobility, meat and dairy consumption, as well as heating are the most dominant components of household footprints. Second, household living situations (demographics, size of home) greatly influence the household potential to reduce their footprint, even more than country or city location. Third, household decisions can be sequential and temporally dynamic, shifting through different phases such as childhood, adulthood, and illness. Fourth, short term voluntary efforts will not be sufficient by themselves to reach the drastic reductions needed to achieve the 1.5 °C goal; instead, households need a regulatory framework supporting their behavioral changes. Fifth, there is a mismatch between the roles and responsibilities conveyed by current climate policies and household perceptions of responsibility. We then conclude with further recommendations for research and policy.
