Abstract:The building and construction sectors together account for 39% of the global CO2 emissions (UN Environment and International Energy Agency, 2017). Thereby, transport accounts for almost a quarter of the total greenhouse gas (GHG) emissions in the EU, where road transport is responsible for 70% of the transport emissions. The Netherlands has set the goal to reduce GHG emissions with 49% by 2030. This results in a demand to reduce CO2 emissions for companies. LBA Groep came with the initiative to implement new techniques like a Mobile Mapping System (MMS), a scanner that dynamically measures the environment, for the reduction of CO2 emissions. This raises the question: What impact does Mobile Mapping (MM) have on CO2 emissions in the Geodesy, Building and Civil Engineering industries and what other purposes does MM have that might have an impact as well? This research assesses the initiative to implement MM as a mean to reduce CO2 emissions and replace traditional working methods (TWM) in the respective industries. In this context, the TWM is defined as the way work is currently carried out without implementing new technologies. Based on a literature review and a desk research within LBA Groep, an understanding of MM is created, and applications and challenges are defined. Besides, semi-structured interviews were performed with two employees of LBA Groep to get an understanding to what criteria certain projects must comply to be carried out with MM. The criteria resulted in a selection of 14 projects. These are assessed on their CO2 emissions using the TWM and by applying MM, whereafter the two methods are compared. The assessment is performed using quantitative data analyses and establishing a method to estimate the emissions. To test whether MM could have an impact industry wide, a water Authority and several contractors are interviewed to give their view on implementing MM and provide insights on the applications in their expertise. In this research, 14 projects are evaluated. Data analyses reveals that emissions could be reduced by 44 up to 72% depending by implementing MM. Emissions are primarily caused by travel movements of projects. However, projects performed with the TWM with a low return rate experience an increase in emissions when carried out with MM. In order to reduce CO2 emissions, travel movements should be decrease. The possibilities of MM vary from asset management to dike measuring. The market chain shows interest in using MM causing an enlarged impact of MM in the industries. The growing interest in technical innovations is important for MM to flourish. However, some parties do not see the benefits yet. This research also contributes to LBA Groep’s goal to stay certificated at level 4 on the CO2PL. Further research is needed to look at the economic feasibility of implementing MM at a large scale and what is needed to execute certain survey methods with MM.
