Envisioning Future Low-Carbon Lifestyles and Transitioning Instruments: Yokohama, Japan

Published on February 14, 2022

In Yokohama, household consumption is responsible for the annual emission of about 7.1 tons of CO2 equivalent per person per year. This calls for a reduction of household consumption emissions by 64 per cent or more for achieving the target of 2.5 tons of CO2 equivalent by 2030 and implementing lifestyles in line with the 1.5 °C target of the Paris Agreement.

The project participants envision Yokohama to continue its prominence of innovation, cultural diversity, beaches and hills, and with ample green spaces. Having one of the most inclusive transport strategies, the Yokohama citizens envision building upon this and find more alternative forms of public transport to reduce private car use. In addition, several PV urban farms and roof top solar PVs are installed, renewable energy is used, citizens make informed food choices and reduce red meat consumption, and urban parks will serve multiple functions, including vegetable and fruit gardens.

The Science is uncomfortably clear. The Paris Agreement proclaimed that we must “limit global warming to well below 2, preferably to 1.5 degrees Celsius…” (UNFCCC, 2015) in order to mitigate unprecedented impacts of climate change such as further biodiversity loss and the deterioration of public health. Many of us feel an urgent need to combat climate change and its impacts.

196 countries agreed to the Paris Agreement. It is understood that to limit global warming to 1.5 degrees Celsius, we must change our way of living. We simply cannot continue on our current path of consumption. Reaching this goal requires social and economic transformation.

Nevertheless, the urgency of transitioning towards more sustainable lifestyles is often underestimated. Everyday living needs to be transformed at the size, scale and urgency required because the decisions we make to meet our daily needs for food, housing, mobility and leisure greatly impact the planet and the people around us. Prioritizing what we can all do can generate the momentum for change we need! In addition, our individual behavior changes must be accompanied by broader systemic and structural changes, including new institutions and infrastructures that embody the ethos of sustainability.

At this point you might ask yourself how we can actually achieve social change. We believe that a first step towards making sustainable lifestyles the social norm is to share the experiences of citizens who already tried to make 1.5 degree living a reality. So, we better understand which lifestyle changes are realistic, possible and even improve our own wellbeing. On the other hand, we can learn from the challenges and difficulties that are connected to lifestyle changes and at the same time identify the supporting measures that governments and cities need to put in place to speed up the process to a more sustainable future.

What emerges from the project is a mosaic of community-generated future lifestyle visions and experiences of households living with the low-carbon options complemented with scientific findings that show the emissions reduction potential in the areas of housing, mobility, nutrition, consumer goods & services, and leisure.
