Greenhouse Gas Emission Calculation of Trenchless Technologies

Category: Environmental Issues
Presenter: Heikki Aakko
Organization: Gidon Infra Oy
Date: 8 May 2024
Time: 10:00 US EST, 16:00 CEST


In the webinar, I’ll give a short summary of my thesis, explaining the general principles used to develop the theoretical framework for calculating and estimating emissions of different trenchless techniques in carbon dioxide equivalent (CO2e). Although the calculator itself is not publicly available, I will go through the general ideas of how the calculator was constructed, what kind of challenges there were building it, and what other observations were made. I will explain the relevance of my thesis and its need and the key objectives, like transparency, credibility, and adaptability. It is important to understand all the relevant variables and acknowledge which factors are not accounted for.  Some calculation examples from the thesis will be presented, and what can be concluded based on the results and which questions still need further research. The outcome from the sensitivity analysis part of my thesis will be explained, i.e., how changes in variables affect the results. Finally, I will summarize all the key takeaways from my thesis, explain the conclusions on what should be done in the future, what can be done based on my thesis, and what can be done to lower CO2e emissions when it comes to trenchless technologies.
