During London Climate Action Week 2025, the Swedish Embassy, the Swedish Chamber of Commerce, and Volvo Construction Equipment (Volvo CE) hosted a pivotal roundtable discussion aimed at accelerating the shift to zero-emission construction machinery. The gathering brought together industry experts, policy leaders, and air quality advocates to address the urgent public health crises caused by urban air pollution. Diesel-powered compact construction machines, widely used in cities, were highlighted as major contributors to harmful emissions yet remain largely exempt from low-emission zone regulations—a gap that threatens efforts to improve urban air quality.

The event, held at the Swedish Embassy, underscored the pressing need for collaborative action to promote zero-emission alternatives. London, where construction equipment has recently surpassed cars as a dominant source of black carbon emissions, illustrates the critical stakes. Mete Coban MBE, deputy mayor for environment and energy, emphasised that reducing emissions from construction machinery is a key strategy within the city’s plan to achieve zero emissions in construction by 2040. He framed clean air as a social justice issue and called for continuous innovation and partnership to protect public health and build a greener urban environment.

Rosamund Adoo-Kissi-Debrah CBE, founder of the Ella Roberta Foundation, reinforced this urgency by calling air pollution a public health emergency. She stressed adherence to WHO air quality standards as a minimum benchmark and referenced “Ella’s Law,” advocating for legal recognition of the right to clean air—especially to safeguard future generations. Such calls come amid alarming data: London’s approximately 5,000 diesel compact excavators emit NOx and particulate matter at levels comparable to over 100,000 diesel cars, yet these machines remain outside Ultra Low Emission Zone (ULEZ) restrictions. Globally, air pollution linked to 8.1 million premature deaths in 2021 underlines the universal urgency of tackling emissions in all urban sectors.

Zero-emission electric construction equipment presents a clear solution. These machines produce no tailpipe emissions, lower vibration, reduce noise, and improve urban living conditions. However, challenges around infrastructure, such as reliable on-site charging, remain barriers to adoption. Volvo CE has been pioneering ways to overcome these hurdles, including trials with Transport for London (TfL) and contractor FM Conway. A nearly 12-week trial substituting diesel machines with electric alternatives in London removed close to 8kg of NOx and non-methane hydrocarbons—equivalent to avoiding emissions from a diesel car travelling nearly 63,000 kilometres. This demonstrates the significant potential to cut pollution by scaling zero-emission technology in compact machinery, which, despite being smaller, disproportionately contributes over half of NOx emissions in the European construction sector.

The trial at Redcliffe Gardens also showed early environmental benefits with electric excavators and wheel loaders supporting safer, cleaner urban construction, contributing to London’s net-zero ambitions for 2030. Early findings noted a saving of over 100kg of CO2 in just two weeks from the electric excavator alone, comparable to removing a car journey of 600 kilometres. Addressing practical issues such as charging infrastructure, Volvo CE and its partners have introduced mobile power units and reliable solutions for urban worksites, pushing the boundaries of what electric construction technology can achieve.

Volvo CE’s commitment extends beyond trials, showcased at Bauma 2025 with the launch of a zero-emission-only product lineup including electric wheel loaders, excavators, and material handlers. This move signals a broader industry shift toward sustainable innovation, supported by flexible charging infrastructures like the PU40 mobile power unit. These developments align with the wider Volvo Group portfolio, which features an array of fossil-free powered equipment and comprehensive solutions aimed at helping customers transition to net-zero emissions while improving urban air quality.

The roundtable concluded with a call for cities worldwide to integrate construction machinery into their clean air policies, including extending low-emission zones to cover diesel compact equipment. Stakeholders were urged to foster cross-industry cooperation and embed sustainability criteria in public projects to create healthier urban environments. With construction emissions rising in prominence as a public health threat, coordinated actions like those led by Volvo CE, government bodies, and advocacy groups represent vital steps toward cleaner, breathable cities for all.
