Throughout the Emission-free Construction Sites project, the importance of dialogue between stakeholders has been repeatedly emphasised. Lack of communication appears as a barrier in several areas throughout this report. It appears in the context of logistical and organisational barriers on site, leading to mismatched schedules and improper handling of building materials. It also emerges when new methods are implemented, as a lack of communication between those who understand the project’s goals and those who execute the work creates challenges.
Many of the barriers identified in this report are closely tied to time and cost pressures in the construction industry, including the lack of communication. Time constraints are often driven by the need to keep costs low as longer projects means increased costs. This focus on completing projects quickly and cheaply limits the ability to adopt new technologies or practices that could reduce emissions.
The high upfront cost of emission-free machinery and the time needed to adapt to these new technologies make it challenging to shift away from traditional methods. Similarly, delays in building the infrastructure needed for electric or hydrogen-powered equipment stem from the reluctance to invest in systems that may not deliver immediate financial returns.
The underlying reason for these challenges is the current economic structure, which prioritises fast and cost-efficient construction. This same structure often favours building new rather than reusing or renovating, even though reusing buildings would significantly reduce emissions. The focus on short-term cost savings and growth makes it challenging to shift towards more sustainable practices.
Overcoming these barriers will require not just technological and financial solutions but also a broader rethinking of priorities in the construction industry to make sustainability a central goal.
