Abstract [sv]

Detta är en studie om klimatpåverkan i samband med anläggandet av järnvägsbroar i syfte att ta fram nyckeltal (moment, material, mängder) för att effektivt kunna reducera utsläppen av växthusgaser. Till grund för studien har vi arbetat med Trafikverkets verktyg klimatkalkyl 2.0. Det har granskats utifrån användarvänlighet och riktighet i indata och emissionsomräkningsfaktorer. Det för att se till skillnaden mellan modellen och ett unikt anläggningsprojekt, var skiljer sig Trafikverkets typvärden mot de projektspecifika förutsättningarna samt vilka blir dess konsekvenser?

Studien har kommit fram till att utan viss försiktighet vid arbete i klimatkalkyl 2.0 finns risk för inkorrekta resultat. Dessutom har studien påvisat tvivelaktiga standardvärden för betydande poster.

Utöver dessa resultat har studien konstaterat att de mest betydande delarna för det unika anläggningsprojektets utsläpp är reduktion av mängden stål och betong samt att hitta leverantörer som kan bevisa låga emissionsfaktorer. Med relativt enkla åtgärder skulle det unika anläggningsprojektets totala utsläpp av koldioxidekvivalenter minskas med nästan 20%.

Abstract [en]

This is a study on the climate impacts associated with the construction of railway bridges in order to develop key performance indicators such as operation, material and amounts to effectively reduce greenhouse gas emissions. The basis of the study has been work in Trafikverkets tool klimatkalkyl 2.0. It has been reviewed on the basis of ease of use and accuracy of input data and emission conversion factors. That’s because we wanted to see the difference between the model and a unique project. What was different and why?

This study has concluded that without some care and work in klimatkalkyl 2.0 is a risk of incorrect results. In addition the study demonstrated questionable defaults for significant items. In addition to these results the study found that the most significant parts of the unique projects emissions is reducing the amount of steel and concrete and to find suppliers who can demonstrate low emission factors. With relatively simple measures could the unique projects total carbon emissions be reduced by almost 20%
