Yokohama City Sewerage Decarbonization Plan

Of the greenhouse gases in Yokohama City Hall's office work, emissions from the sewerage business are the second largest after the general waste treatment business, accounting for about 20% of the entire city hall. In order to prevent the worsening global warming, we have formulated the Yokohama City Sewerage Decarbonization Plan, which systematically summarizes specific initiatives, in addition to medium- to long-term targets and roadmaps for achieving them. Based on this plan, we will work on global warming countermeasures to achieve our goals in all measures in the sewerage business.

Reduction targets

We aim to reduce emissions by 50% in fiscal 2030 (compared to fiscal 2013) and achieve net-zero emissions by fiscal 2050 (carbon neutrality).
