The contribution of emission reduction possibilities provided by preconstruction to the climate targets of cities

Abstract

Preconstruction means actions that are carried out when an area to be constructed is geotechnically too soft or difficult to construct and the area must be for example solidified or mass in the area must be exchanged. As infra construction is very energy intensive, preconstruction provides possibilities for significant emission reductions when the preconstruction alternatives, areal mass balance and alternative materials generated in the vicinity has been mapped early enough in advance.

The objective of this thesis was to study emission reduction potential in preconstruction activities and how considering the preconstruction alternatives can contribute to the climate targets of cities.

Literature review and CO2 emission calculations for actual cases were studied in this thesis. The cases presented in this study are Ramboll Finland’s client cases calculated for the cities of Helsinki, Turku and Tampere. The calculation method used in the case examples is developed by Ramboll for CO2 emission calculation purposes in infra projects following the standard CEN/TC 350 Sustainability of construction works.

The results of this thesis will contribute to cities climate target calculations, as well as to national UUMA3 project objectives.
