Issue Focus

First, challenges and tasks of individual construction companies Strategic tasks for carbon emission reduction by individual construction companies can be divided into building sector, transportation sector, and construction site sector. In the case of buildings, energy efficiency improvement of heating and cooling and lighting facilities of buildings owned or used by construction companies, green remodeling of office buildings, or zero-energy building construction can be applied. In the case of a construction site, energy efficiency improvement at the construction site, energy reduction construction methods including OSC(Off-Site Construction), and construction waste reduction measures can be applied. Second, challenges and tasks for the total life cycle of construction products The tasks to reduce carbon emissions in the total life cycle of construction products can be divided into increasing the proportion of purchases of low-carbon materials and strengthening the capacity to provide solutions for zero-energy construction products in the operation stage. Increasing the proportion of low-carbon material purchases is to strengthen cooperative relationships with construction material producers that have reduced embodied carbon and expand the purchase proportion of low-carbon materials. In particular, it is necessary to increase the proportion of carbon emission reduction material purchases by establishing networks with companies that have carbon reduction technology among steel and cement production companies with high carbon emission among construction materials, and low-carbon material producers (slag cement, low-carbon concrete, etc.). In addition, it is necessary to strengthen cooperative relationships with low-carbon construction material producers and to continuously discover alternative materials and producers. Third, challenges and tasks for responding to changes in the construction market Lastly, it is also necessary to establish and implement a strategy to respond to the expected changes in the construction market(growth/decrease in specific construction products) following the implementation of the carbon-neutral scenario. Markets that are expected to grow according to the carbon-neutral scenario are carbon emission reduction construction products such as renewable energy plants and zero-energy buildings following energy transition scenario. In the case of renewable energy power plants such as solar and wind power, construction companies participate(share participation, construction work, etc.), which not only improves performance, but also has the advantage of securing renewable energy that can reduce carbon in Scope 1 and 2 areas. In the case of zero-energy buildings among construction products that reduce carbon emissions, the market is expected to grow after 2025, when certification grades are applied to private buildings. On the other hand, according to the 2050 carbon-neutral scenario, additional construction of coal-fired power plants is expected to disappear in the future, and LNG power plants may also be reduced differently from the original plan. However, it would be desirable to strategically reduce resource allocation by comprehensively considering the real situation in which it is difficult to achieve a rapid energy transition in the future, changes in the future basic plan for electricity supply and demand, and overseas market trends.
