generation required. This lowers the capital and operating costs of these vehicles, thereby accelerating market adoption. Ultimately, this means combining the most efficient technologies of today and tomorrow with the older machines of the past to reduce energy demand. Until full electrification can be achieved, this combination is the best and most practical solution available, and the results are impressive. We can improve a machine’s energy efficiency in three ways. The first is by reducing idle losses with variable displacement pumps, digital displacement, and decentralised drives. Machine usage data available through telematics can also be used to advise optimisation opportunities. The second way to improve energy efficiency is to reduce hydraulic losses with solutions such as individual metering control, direct-driven hydraulic actuators, digital hydraulics, and multi-chamber actuators. And finally, through the development of energy recovery systems, we can recycle the unused energy during operations such as boom lowering and slew deceleration. Some of technologies that we are seeing increasingly adopted can already deliver fuel savings of between 15-30% in excavators over 15 tons while at the same time increasing the work capacity of the machines. We believe it will soon be possible to reach fuel savings of up to 50%. Construction has a role to play in battling climate change Major metropolitan areas are proving to be a powerful force in decarbonization by demanding zero-emission operations, including on construction sites. Until recently, low-emission construction seemed unattainable. But as regulations for greenhouse gas emissions and sound pollution have been enacted, market innovations have gained traction, paving the way for change in the construction industry. Many cities around the world are now prioritizing different ways to reduce emissions from the construction sector. However, the pace needs to increase rapidly. The good news is emissions reduction can be accelerated greatly through the continued development of innovations and adoption of efficient technologies that are already available. Construction OEMs and contractors play a key role in building the new cities of tomorrow, but all organizations involved in the supply chain must collectively take steps to decarbonize the industry. Doing so will unlock significant environmental, health, and economic benefits. We have the solutions; now is the time for action. 1 IEA (2021).
