Sammanfattning
This study evaluates the cost-effectiveness and feasibility of climate improvement
measures in civil construction by comparing alternative materials and fuels for asphalt,
concrete, and heavy machinery. The research addresses a growing demand
for sustainable infrastructure by analyzing the marginal abatement cost (MAC)
of selected measures to reduce greenhouse gas emissions. Through a combination
of literature review, interviews with industry professionals, and quantitative data
from Skanska’s operations, the study constructs a Marginal Abatement Cost Curve
(MACC) tailored to a hypothetical mid-sized civil project. Key findings highlight
that certain measures, such as using recycled asphalt with bio-based binders and
transitioning to electric machinery, can offer both environmental benefits and economic
advantages. However, barriers such as procurement practices and knowledge
gaps among stakeholders often hinder adoption. The thesis concludes by emphasizing
the importance of integrating environmental and financial assessments into
project planning to support cost-efficient decarbonization strategies in the construction sector.
