Many studies have been conducted on the contributions of the construction industry to greenhouse gas (GHG) emissions. However, these studies focused on the embodied GHG emissions of buildings and were restricted by limited system boundaries due to a lack of detailed on and off-site process data, especially data for assembly and miscellaneous works as well as construction related human activities. This study therefore analyzed GHG emissions during the construction phase of a case study building on the basis of an extended system boundary in the context of China by utilizing detailed onsite process data. The results show that indirect emissions accounted for 97% of all GHG emissions. On-site electricity use and building materials production were the two greatest contributors to direct and indirect emissions respectively. Recombining the construction activities revealed that construction related human activities generated significant GHG emissions (385 tCO2e), which have been ignored in previous research. The findings also reveal that although some materials used during the construction process are negligible in terms of weight, such as polyamide safety nets and aluminum (<0.1%), they have a considerable impact on GHG emissions (2-3%).

“…Because the framework is driven by the limited information in the planning phase of road projects, the framework meets the requirements of the present study. A detailed procedure for the estimation can be found in Kim et al (2012). The average estimates by design speed were 257 tCO 2 e for a design speed of 100 km/h and 180 tCO 2 e for a design speed of 80 km/h.…”

Road construction is a primary cause of the loss of ecosystems and their services. However, such loss of ecosystem services has not been reflected in key decision-making processes, such as in cost-benefit analysis due to difficulty in pricing the cost. This study proposes a framework for pricing the loss of regulating ecosystem services caused by road construction. Two important characteristics of the proposed framework are the adoption of the replacement cost method and the use of limited information in the planning phase of road projects. A case study was conducted to validate the proposed framework, with an emphasis on carbon sequestration, flood mitigation, and water storage services, based on 49 typical road construction projects in the Republic of Korea. On average, the costs of the loss of carbon sequestration, flood mitigation, and water storage services were estimated to be 5,055, 6,412, and 8,004 in units of $/lane-km, respectively, and the total costs were estimated to be an average of 19,474 $/lane-km, accounting for 0.47% of the direct construction cost. These findings are the effort for pricing the loss of ecosystem services caused by road construction from an engineering perspective. The proposed framework can be used to provide clear guidance for sustainable development.

In China, the construction of asphalt pavement has a significant impact on the environment, and energy use and greenhouse gas (GHG) emissions from asphalt pavement construction have been receiving increasing attention in recent years. At present, there is no universal criterion for the evaluation of GHG emissions in asphalt pavement construction. This paper proposes to define the system boundaries for GHG emissions from asphalt pavement by using a process-based life cycle assessment method. A method for evaluating GHG emissions from asphalt pavement construction is suggested. The paper reports a case study of GHG emissions from a typical asphalt pavement construction project in China. The results show that the greenhouse gas emissions from the mixture mixing phase are the highest, and account for about 54% of the total amount. The second highest GHG emission phase is the production of raw materials. For GHG emissions of cement stabilized base/subbase, the production of raw materials emits the most, about 98%. The GHG emission for cement production alone is about 92%. The results indicate that any measures to reduce GHG emissions from asphalt pavement construction should be focused on the raw materials manufacturing stage. If the raw materials production phase is excluded, the measures to reduce GHG emissions should be aimed at the mixture mixing phase.
