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 project participants of the household experiments held in Yokohama thought it was an interesting experience and wish to continue on the path towards 1.5-degree lifestyles. The participants think it is crucial to raise awareness to involve more people across all generations. The participants have also shared their experience in learning more about eco-tourism and places to visit in the area. Community spaces are among the places where these exchanges have been held, and a place to reach out and collaborated with more people in the local communities.

One of the participants shared her way of reducing clothes consumption due to a child’s growth. The participant finds second-hand clothing in good condition and quality, adjusts the size to fit the child and can therefore extends the lifespan of the clothes. When the child outgrows the clothes, the clothes are passed on to another child.

Fixing the length of a child’s dress… This is my idea of not wasting clothes.

While many of the participants showed a great interest in considering and adopting low-carbon lifestyle options to their everyday lives, a few barriers were found in some of the options. An example is the different road conditions for changing to riding bicycles – the traffic changes depending on the city location.
