Ecological Mission 2030-2050

Setting New Medium and Long-term Goals

Shimizu recognizes the issue of climate change resulting from CO2 and other greenhouse gas emissions as one of the most important issues we face, and we are implementing measures related to mitigation of and proper responses to climate change. We are also acting to reduce CO2 emissions from our own business activities during construction and at our offices, as well as CO2 emissions by customers as they operate the buildings that we have designed, built, and delivered to our customers, over the lifecycle of these buildings.

We have integrated these activities and launched a wide range of Ecological Mission activities in fiscal 2005 to mount a comprehensive response with the goal of saving energy and reducing total CO2 emissions 30% by 2020, compared to the 1990 level. This will be achieved by reducing emissions from our offices and job sites, and through the construction of energy-efficient buildings. Meanwhile, COP21 was held in Paris in 2015, marking a critical juncture. Japan declared the goal of a 26% reduction by 2030 compared to 2013 emissions levels, and countries around the world also announced their new goals. The Japan Federation of Construction Contractors also set the medium-term goal of a 25% reduction in CO2 emissions per base unit during construction by 2030, compared to 1990 levels.

Shimizu also took this opportunity to formulate Ecological Mission 2030-2050 to set new medium and long-term goals in light of Goal 13 (specific measures to combat climate change) of the Sustainable Development Goals (SDGs).
We have established the category of emissions produced directly from Shimizu's construction and office activities as part of the CO2 emissions that Shimizu is associated with. We pursue company-wide efforts to reduce these emissions, have set a goal in terms of the percentage reduction from 1990 levels, and use this as the KPI to manage reduction efforts. Moreover, Shimizu's energy-efficient design technology can make a substantial contribution to reducing CO2 emissions over the lifecycle of a building as it operates after Shimizu has completed the design and construction and delivered it the customer. We therefore have also established a similar KPI for the percentage of reduction compared to 1990 levels and use this in management.
The three categories for which KPI have been set specify the reduction goals for 2030 and 2050 as the medium and long-term reduction goals for the entire company, and we pursue initiatives to achieve these goals.

Shimizu Corporation is committed to the formulation of SBT (Science Based Targets) to achieve the long-term goal of the COP21 Paris Agreement on climate change.
We are analyzing several climate change scenarios and are considering setting medium- and long-term targets consistent with SBT.

Shimizu's Own CO2 Reduction Efforts

Improvement in Construction Methods

Fiscal 2016 Results: Reduction of 42,000 tons in CO2 emissions

Improved construction methods for the design and construction of buildings that result in lower CO2 emissions compared to existing structural or construction methods

Green Procurement

Fiscal 2016 Results: Reduction of 56,000 tons in CO2 emissions

Pursuing the use of environmentally friendly materials (blast furnace B-type cement, etc.) in procuring concrete for use at job sites.

Energy-saving Upgrades and Building Management

Fiscal 2016 Results: Reduction of 30,000 tons in CO2 emissions

The diagnostics performed on existing buildings and subsequent proposals led to construction work on energy-saving upgrades. Shimizu BLC Co., Ltd., an affiliate of Shimizu, analyzed and made operating improvements to these buildings.

Reduction in Construction By-products

Fiscal 2016 Results: Reduction of 18,000 tons in CO2 emissions

CO2 emissions during transport, processing, and disposal are reduced by reducing construction by-products generated from job sites.

Renewable Energy

Fiscal 2016 Results: Reduction of 10,000 tons in CO2 emission

The 3 MW Kitakami solar power plant began operating in Kitakami, Iwate Prefecture in April 2015. This is Shimizu's second mega solar plant next to the Ako solar power plant (output of 10 MW) which is already in operation.

Acquisition and Use of Emission Credits

Fiscal 2016 Results: Reduction of 19,000 tons in CO2 emissions

We are implementing a CDM project that collects methane gas from landfill sites in Yerevan, Armenia and Tashkent, Uzbekistan.
