Sammanfattning
The construction sector accounts for a large part of the greenhouse gas emissions
that are released in Sweden each year. Within the sector the environmental focus
has up until recently mostly been about decreasing the need for energy during the
operation phase. However, now with more energy-efficient solutions, the focus has
shifted more towards decreasing the negative impact caused by building materials.
This change can clearly be seen in the Swedish environmental certification system
Miljöbyggnad, which puts significantly higher demands on the material indicators
in their last version, Miljöbyggnad 3.0. This has resulted in questions among the
actors who use it. With this background the aim of this report was formed. Evaluating
and clarifying what the new material requirements in Miljöbyggnad 3.0 mean
for the actors in the construction sector. The report should answer if the market is
prepared to meet the demands of materials and services needed to reach grade gold
in the three material indicators.
To answer this, the current state of knowledge has been investigated. Looking at
what has been written about the sector’s view on environmental certification, as
well as what is currently being discussed regarding the three material indicators;
documentation of building materials; phasing out hazardous substances; and the
climate impact of structural framework and foundations. Furthermore, to connect
the literature to reality a case study was performed, including interviews with people
related to a particular project. From the study it was shown that there are
different opinions among the actors, regarding the consequences of this new version.
What is shown to be questioned the most are non-documented building materials
and uncertainties around the indicator considering the frame and foundation. Some
actors think the requirements in this particular indicator could be presented more
clearly, and that the requirements regarding EPDs (environmental product declarations)
are not connected to reality. Mostly, this concerns the concrete industry,
which due to having many recipes for their concrete, finds it difficult to fulfill this
requirement. Two suggestions for how this issue could be handled have been stated
during the interviews, and now the decision-makers of the system have to form an
opinion regarding those. Finally, from the report it can be concluded that it is
possible to reach grade gold in indicator 13 and most likely in indicator 14. As for
indicator 15, the market is not in line with the requirements. Thus, today it is not
possible to reach grade gold.
