Mitigation actions

Project to promote environmentally conscious business activity
This measure requires businesses of certain scales to develop an environmental business plan every 3 years and to report its progress annually to Hiroshima City. The City analyzes and publicizes these activities and progress towards reducing greenhouse gas emission on its website to allow community members to view these achievements and to promote businesses to take planned action towards mitigating climate change. Start year 2010

Project to Produce Fuel from Sewage Sludge
Hiroshima City generates energy from sewage sludge instead of using coal fired electricity to promote the recycling of sewage and to reduce greenhouse gas emissions. Prior to the project, sewage sludge generated at the City's sewage facility was disposed in three ways: composting, converting it to cement raw-material, and incinerating and land-filling. This project enabled the City to reduce its greenhouse gas emissions caused especially by incineration and land-filling. The City has also been able to reduce the amount of greenhouse gas emitted by the sewage sludge project itself by utilizing the biogas produced through the energy generation process. Start year 2009

Subsidy for renovation of eco-friendly equipments in private buildings
The project subsidies a part of costs to renovate existing equipments into eco-friendly in private firms in Hiroshima city with the government’s regional Green New Deal funds.

The plan targets existing buildings (except new and extended constructions) to carry out : multiple renovations ( more than two equipments in a firm) or integrated renovations ( identical energy-saving equipments in more than two firms) of energy-saving equipments (air-conditioners, hot water supply systems, lightings, heaters, electric equipments, natural gas co-generation equipments, heat insulation and etc.), and renewable energy equipments (solar power generation, solar heating systems, biomass energy and etc.) that the City determined. The project was carried out by three companies in fiscal 2010 ?Amounts of CO2 emission reduction is a predicted figure in fiscal 2011 Start year 2010
