Carbon dioxide emitted from construction work in Japan was as low as 1.3 percent of total carbon dioxide emissions in 1995. The industrial input-output table was used to calculate the percentage of carbon dioxide emissions in each year. According to this calculation, the percentage was 1.2 percent in 1985 and also in 1990, showing no remarkable change in this ten-year period. However, the data on consumption of electricity, kerosene, light oil, etc. in construction work had not been collected in a unified manner until a few years ago, because the rate of carbon dioxide emissions from construction work was extremely small, and also because the Japanese construction industry has a multilayered structure. In the wake of recent nation-wide moves to arrest global warming, some construction companies have taken the lead in cutting carbon dioxide emissions from construction sites. In order to promote such emission-cutting activities throughout the construction industry, use of carbon emission units is effective in the determination of carbon dioxide emissions.
