# Section 2 Initiatives at Home

As many of today’s environmental problems are attributable to our daily living and business activities, it is of great importance that efforts be made to reduce environmental load at home where we carry out our daily activities. Residential energy consumption is increasing yearly along with the growing number of households and diffusion of home electrical appliances. $ CO_{2} $ emissions from energy consumption by the residential sector account for approximately 14% of all Japanese $ CO_{2} $ emissions from energy consumption. The amount has increased by approximately 30% from the base year (FY1990) of the Kyoto Protocol, marking a substantial growth rate compared with other sectors.

To cultivate “people” who can help build a sustainable society, the home plays an integral role. Home is the place where small efforts can gradually produce big effects. It is where a slight shift in one’s point of view can reduce environmental load while achieving “high quality of life” or “enjoyable life.” Furthermore, as home discipline such as “turning off lights,” “not brushing teeth with water running,” and “using things with care” help to instill the idea of mottainai, it can be said that the home is the starting point of nurturing “people” needed for the sustainable future.

CO $ _{2} $ Emissions by Sector

1. The inner circle shows the percentage (figures in lower parentheses) of direct emissions of each sector, and the outer circle shows the percentage (upper figures) after allotment of emissions resulting from power generation by electric utility companies and emissions resulting from heat generation by heat service utilities to final demand sectors, according to their electric consumption and heat consumption.

2. Due to statistical error and rounding, the sum of percentages of emissions may not necessarily add up to 100%.

3. “Other” includes fugitive emissions from fuels and electricity and heat allotment errors.
