Carbon management in geotechnical engineering solutions
Carbon management in geotechnical engineering solutions
The construction sector is a significant contributor to greenhouse gas (GHG) emissions, mainly because of the emission intensive construction materials. Integrating carbon accounting and management into the geotechnical design process of infrastructure projects can effectively reduce embodied carbon from land use planning through to the detailed design phases. A low-carbon geotechnical approach includes appropriate ground investigations, soil and rock mass coordination and comparisons of different foundation and soil improvement methods. In the detailed design phase, chosen foundation and soil improvement methods can be optimized for carbon emissions through material choices, transport planning, and considering life cycle durability. This paper presents the possibilities of geotechnical engineering solutions to decarbonise the infrastructure sector. Carbon emissions and costs for various ground improvement and foundation methods, including alternative solutions with recycled materials, are reported, and compared. The considered case studies and scenarios represent infrastructure projects located in Finland.
