Decarbonization in construction is becoming one of the most urgent challenges for the global building industry. As the climate crisis intensifies, recent international studies suggest that emissions generated by construction activities could significantly undermine efforts to limit global warming to 1.5°C and 2°C over the next two decades.
According to recent research, more than 70% of the total emissions associated with a new building originate from construction processes and material production. Without decisive action, emissions generated by construction activities are expected to double by 2050. In this scenario, technological optimization, equipment efficiency and systematic control of construction equipment are becoming essential to reduce CO₂ emissions on job sites.
Why decarbonization in construction is now a climate priority
The construction industry has reached a historic turning point. Until now, sustainability policies have focused primarily on reducing so-called operational emissions, namely the energy used for heating, cooling and lighting completed buildings. However, the latest scientific evidence calls for a profound shift in perspective, bringing attention to the carbon footprint of the construction supply chain itself.
A study published in October 2025 in Communications Earth & Environment, a Nature journal, outlines a critical scenario: without radical intervention, global emissions generated by construction activities alone are projected to double by 2050, potentially exhausting the remaining global carbon budget required to keep global warming within the 1.5°C and 2°C thresholds.
The share of carbon emissions generated by unsustainable construction materials is considerably lower in regions characterized by stricter environmental regulations and more advanced building standards, reaching approximately 29–30% in the United States and 27–40% in the European Union. Significantly higher figures are recorded in markets where the transition toward sustainable construction practices is still underway, such as China, where estimates range from 43% to 73%, and India, where they range from 50% to 61%.
From operational emissions to decarbonizing construction sites
For many years, sustainability strategies in the building sector have focused mainly on reducing operational emissions. These are the emissions generated during the use phase of a completed building, including the energy required for heating, cooling, lighting, ventilation and daily operation.
This focus has helped improve the energy performance of buildings once they are in use. However, recent research shows that a significant share of a building’s total carbon footprint is generated much earlier, before the building is even completed. These emissions come from material production, transport, construction processes and the operation of machinery on job sites.
Further reinforcing these concerns is a study conducted by Aalto University and published in June 2025, which found that more than 70% of total emissions associated with new buildings stem directly from construction processes and material production rather than from the operation of the finished structure.
Modern construction sites require enormous mechanical power, historically driven by fossil fuels and by equipment that is not always optimized for efficiency. The challenge of climate sustainability must therefore be addressed at its source by transforming construction practices and maximizing the hydraulic and mechanical efficiency of the heavy machinery used on construction sites every day.
For this reason, decarbonizing construction means looking beyond the finished building and focusing on the equipment, materials, processes and technologies used throughout the entire construction phase.
How hydraulic efficiency advances decarbonization in construction
Hydraulic systems play a central role in the performance of construction equipment, from excavators and loaders to compact machines and mobile equipment. When hydraulic circuits are not optimized, energy losses, pressure drops, fluid leaks and inefficient connections can increase engine load, fuel consumption and emissions.
Improving hydraulic efficiency helps reduce these losses. More efficient hydraulic components support better power transfer, lower mechanical stress and smoother machine operation. As a result, construction equipment can perform the same tasks with less wasted energy, contributing directly to lower CO₂ emissions on job sites.
"In this scenario, technological optimization and systematic control of construction equipment are becoming indispensable," comments Emiliano Torresi, Product Management & Marketing Director at Faster, the Italian company that is a global leader in the design and manufacture of hydraulic connection systems and has been part of Helios Technologies since 2018. "As suppliers to the construction industry, our mission is to provide equipment manufacturers and operators with components capable of delivering maximum energy efficiency without compromising performance. Preventing hydraulic losses and optimizing the mechanical management of heavy machinery translates directly into lower emissions in the field, demonstrating how Italian engineering excellence can play a key role in building a more sustainable future."
Faster’s role in advancing decarbonization in construction equipment
Leveraging its extensive engineering expertise, Faster has conducted an in-depth analysis of construction-site inefficiencies, identifying precise control of earthmoving and construction machinery as a key factor in reducing environmental impact.
Seemingly invisible solutions, such as the company’s high-efficiency quick-release couplings, optimize power transfer within hydraulic circuits, reducing engine load and improving overall machine efficiency.
Even apparently minor factors, such as proper flow management, ergonomic connection systems and spill-free operation, have a tangible impact on job-site efficiency. More ergonomic and user-friendly systems reduce machine downtime and unproductive operations, while optimized hydraulic flow management helps minimize energy losses and engine overloads. At the same time, eliminating fluid spillage reduces waste, environmental contamination risks and unplanned maintenance requirements
Hydraulic connection systems for decarbonizing construction machinery
This vision has led to the development of advanced multi-connection systems for the construction equipment market, designed to enhance reliability, sustainability and operational continuity.
These solutions address the needs of different machine categories, supporting faster, cleaner and more efficient hydraulic connections. By reducing downtime, improving safety and minimizing energy losses, they contribute to the broader goal of decarbonizing construction machinery and improving job-site performance.

Key strategies for advancing decarbonization in construction
Alongside the solutions developed by Faster to improve hydraulic system efficiency and reduce fluid losses, the industry is increasingly embracing additional strategies to accelerate job-site decarbonization.
These approaches combine technological innovation, digital monitoring, material efficiency and operator training to reduce emissions across the entire construction process.
Electrification and hybrid fleets for decarbonizing construction sites
The progressive electrification and hybridization of construction equipment fleets can help reduce the reliance on diesel-powered machinery. Fully electric equipment eliminates direct exhaust emissions during operation, while hybrid solutions can reduce fuel consumption in specific duty cycles by combining combustion engines with electric power support.
This strategy is particularly relevant in urban construction sites, indoor applications and regulated environments, where lower noise levels, reduced local emissions and improved air quality are increasingly important.
Low-carbon materials for sustainable construction
The adoption of low-carbon construction materials is another key lever for decarbonization in construction. This approach focuses on reducing embodied carbon, namely the emissions generated during the extraction, production, transport and use of construction materials.
Lower-carbon concrete, recycled aggregates, reclaimed materials, bio-based materials and optimized material specifications can all help reduce the carbon footprint of buildings and infrastructure before they even enter the operational phase.
Predictive maintenance to improve construction equipment efficiency
Predictive maintenance uses machine data, sensors and monitoring systems to identify potential issues before they lead to failures. In construction equipment, this can help keep machinery operating in more efficient conditions, reduce unplanned downtime and prevent performance losses caused by worn or poorly maintained components.
While predictive maintenance should not be presented as a standalone decarbonization solution, it can contribute to more efficient equipment management and support lower-impact job-site operations.
Fleet digitalization to reduce idle cycles and fuel consumption
Fleet digitalization allows construction companies to monitor equipment use, fuel consumption, idle time and maintenance needs in real time. By identifying machines that are underused, operating inefficiently or spending too much time idling, companies can improve fleet productivity and reduce unnecessary fuel consumption.
Reducing idle cycles is especially important because idling burns fuel without producing useful work. For this reason, digital monitoring can become a practical tool for improving operational efficiency and supporting job-site decarbonization.
Waste recovery and reuse for lower-impact construction sites
The recovery and reuse of inert construction waste directly on site can reduce the need for new raw materials, limit transport requirements and support a more circular approach to construction. Reusing aggregates and other suitable materials helps reduce waste sent to landfill and can lower the environmental impact of construction activities.
This strategy is particularly effective when integrated into project planning from the earliest stages, allowing materials to be managed as resources rather than as waste.
Operator training for more efficient machine use
Advanced operator training is essential to improve machine efficiency and reduce unnecessary fuel consumption. Skilled operators can limit excessive idling, avoid inefficient movements, use equipment more appropriately and reduce stress on mechanical and hydraulic systems.
In combination with telematics and real-time fleet data, operator training can help translate technological innovation into measurable improvements in everyday job-site performance.
