The conventional process used in the operation of the cranes has involved the use of diesel engines, which produce massive emissions of carbon dioxide, nitrogen oxide, and particulate matters. For example, it has been estimated that the large heavy mobile crane could end up using up to 50 to 100 gallons of diesel fuel per day, which, apart from causing environmental pollution in the construction site environment, has significant potential impact on the environment as a whole, thus making it one of the main contributors of climate change based on the estimated number of construction activities that take place in the world.
Sustainable construction cranes can be used in response to a number of environmental concerns. Energy-saving construction cranes fall under the technology of green buildings and have become a norm in the assessment of LEED and BREEAM certification. The construction industry has found itself facing obligations that relate to environmental performance in their applications for works on infrastructure and commercial construction. Construction industry players can now be seen to be facing pressure to align with this in response to their commitments on Paris Climate Deals and having a net-zero carbon footprints.
Research indicates that operation and performance of cranes can potentially be optimized in order to reach reduced emission levels of between 40% and 50% below current levels in the proper equipment selection and design. Apart from estimating emissions, environmental footprints include every dimension with respect to emissions throughout their lifespan, right from their use in production processes that use fossil-free steel to equipment remanufacturing and recycling. It can thus be said that all equipment, including green cranes, will remain sustainable and will not cause emissions for others in their supply chain.
Electric and Hybrid Cranes: Leading the Green Revolution
Electrification and hybridization of crane technology is a highly noteworthy developments in eco-friendly material handling solutions at present. However, this development owes a great deal to advancements in electric-powered tower and mobile electric cranes, which are able to function with a zero-emission level and comparable power performance without noise pollution and coupled with lithium-ion batteries that enable them to run for 6-8 hours without charge.
Electric cranes do not produce exhaust gases; this enhances clean air in the construction environments established in cities. Noise reduction efficiency in electric cranes is valued in cities, where the population is dense and noise standards are required to be observed in construction sites. Construction projects in cities such as Oslo have proven to successfully incorporate construction environments that use electric cranes and other forms of electric equipment.

Mobile cranes and tower cranes play a significant role in projects where environmentally sustainable methods of construction are taken into consideration. Environmental practices related to mobile cranes and tower cranes need to be recognized to enable contractors to select the most appropriate equipment with lower environmental pollution.
Mobile Tower/Crane: These have greater malleability and faster set-up times, which, as discussed, lead to greater sustainability due to faster set-up times and improved transportation factors. The advantages of mobile tower/cranes include minimal site preparation works, which mitigate the need for massive concrete works on site. The versatility of mobile tower/cranes, which allows the execution of the operations and then the relocation to other operations, mitigates downtime and, consequently, the costs and concerns related to emissions. It is pertinent to the greatest number of contractors on the MYCRANE platform that proper utilization of the mobile tower/crane is directly related to avoiding the wastage of fuel and the inefficiency of larger equipment.
Tower cranes, which are stationary on site throughout the life of the project but have positive impacts through efficient lifting on mega projects, have positive impacts through their positioning, which enables accurate repetitive lifting without any waste of energy. The results from the comparison of the sustainability usage of both tower and mobile cranes show that tower cranes have the greatest impact on mega projects, which entail high-rise buildings and hence need vertical lifting that is repetitive and takes a longer period of time, hence justifying the need for setup costs, which may have impacts on sustainability positively or negatively on mega projects. The hybrid power solutions, which include storage solutions such as batteries, were the most effective on tower cranes, where generators were reduced by 50% and fuel by 46%.
The equation regarding the sustainability of tower and mobile cranes is project-reliant on considerations such as project duration, location, lifting capacity, and the availability of electrical power. The project limitations presented on the MYCRANE website can, therefore, be overcome as far as decision-making is concerned on behalf of the contractor, considering the usage of different cranes available, utilizing the service of their Crane Selector. The precision, in this case, removes both underrriting, which involves mobilization, and over-engining, which involves waste.
Energy-Efficient Cranes and Operation Optimization
Besides the change brought about in the power source, energy-efficient cranes also incorporate many other features which are eco-friendly. For instance, there is the use of regenerative braking, which allows for the utilization of the energy that would have been wasted through lowering operations by feeding this energy back into the batteries or by relieving the load on the engine. There is the use of advanced hydraulic systems that minimize heat generation and loss of pressure. There is automated control, which allows for the optimization of the lifting cycle by minimizing energy wastage through motion control.
Performing regular maintenance is a factor that is necessary for the cranes to operate in the most optimal way, which is a very important aspect regarding sustainable methods used in the construction process. Clean engines, well-lubricated components, and properly maintained hydraulic systems contribute greatly to the reduction in both consumption and emissions. There exists software in the shape of telematics solutions that could enable the cranes to track their consumption and set their use accordingly based on optimal values.
Strategic planning of the lift activity A factor that plays a crucial part in the sustainability of the cranes. Down times, relocations, and activities that suck fuel without producing a single product are the concept of strategic planning. Organizing different lifts to provide optimized activities will reduce the working hours of the crane. Reducing the lifting capacity of the cranes according to the needs of the project will help maintain the efficiency of the activities of the crane. Research on the usage of the tower crane in high-rise building projects has proven the effectiveness of the concept of 'Productivity and Carbon Footprint' to optimize the sustainability of the tower crane.
In addition to the above, the MYCRANE system also allows the following optimization methods in various ways, including the following:
