A high-level roundtable held at the Swedish Embassy during London Climate Action Week has spotlighted the outsized role diesel compact construction machines play in worsening urban air quality, and the urgent need for policy and industry to drive the shift to electric alternatives.

The event brought together city officials, construction leaders and researchers to tackle the overlooked issue of diesel compact machinery, which remains largely exempt from regulations such as London’s Ultra Low Emission Zone (ULEZ) despite emitting significant levels of nitrogen oxides (NOx) and particulate matter (PM). Representatives from Volvo Construction Equipment (Volvo CE), the City of London, and campaign groups joined the call for a rapid transition to zero-emission equipment.

In London alone, approximately 5,000 diesel compact excavators currently in use generate as much NOx and PM as more than 100,000 diesel cars. Yet, because they are not required to meet the same particulate filtration standards as passenger vehicles or larger machines, their impact often goes unaddressed.

With construction now the dominant source of black carbon emissions in London, overtaking cars, the urgency is clear. Globally, only 17% of cities meet WHO air quality guidelines, and air pollution contributed to 8.1 million premature deaths in 2021 alone.

Low-emission equipment

The roundtable also showcased findings from a 12-week trial by Volvo CE, Transport for London (TfL), and FM Conway, which replaced diesel equipment with three electric construction machines. The result: nearly 8kg of harmful NOx and hydrocarbon emissions were avoided, which is the equivalent of a diesel car travelling more than 39,000 miles.

Advocates say electric alternatives offer a win-win: quieter operation, lower vibration, zero tailpipe emissions, and less energy waste, making them ideal for densely populated urban areas. But challenges remain: lack of charging infrastructure, green energy access, regulatory gaps and high upfront costs.

As cities look to scale climate and public health efforts, roundtable participants called for collaborative action to overcome these barriers. Embedding sustainability criteria into public tenders, expanding low emission zones to include all construction machinery, and increasing awareness of compact diesel machines’ impact were highlighted as immediate priorities.

The event closed with a strong message: cleaning up construction emissions is not only technically viable but essential to creating healthier cities. With bold leadership, coordinated policy, and cross-industry collaboration, electric construction machines could play a pivotal role in transforming the urban environment.

Thomas Bitter, Head of the Compact Business Unit at Volvo CE, said, “Cities like London are making great progress to improve air quality. But ignoring construction equipment in low emission policies misses a key health opportunity. Zero-emission solutions exist, but adoption is too slow. We need full value chain collaboration to break down barriers to change and speed up the shift to emission-free construction that is so essential for urban health.”

Following the launch of its next-generation excavators for the Middle East and Africa, Volvo Construction Equipment (Volvo CE) recently validated their on-site performance through rigorous comparative testing in the Gulf region

The models – EC210, EC220, and EC360 – went head-to-head with competing machines from top global OEMs in real-world truck loading tasks, assessed on key metrics including productivity, fuel efficiency, durability, operator comfort, safety, and serviceability.

All machines were tested under identical site conditions using a dig-swing-dump-repeat cycle. Operators included a Volvo R&D veteran with 15 years of experience and two local contractors with a combined 22 years of excavator operation. The consistent conditions ensured fair performance evaluation across all brands.

EC210: Power meets precision in 22-tonne class

Delivering stronger productivity and improved fuel efficiency — even at lower RPMs.

In the 22-tonne category, the EC210 stood out by achieving up to 7% greater productivity and 14% better fuel efficiency than rivals in the same weight class. Despite operating at lower RPMs, the machine demonstrated optimal power-to-efficiency balance, making it ideal for applications like roadworks, site preparation, and utilities. "It’s a compact powerhouse, especially for contractors focused on output without excessive fuel costs," said Olle Watz, product manager at Volvo CE Region International.

EC220: Boosted output for bigger demands

Strikes a balance between power and fuel economy in high-volume operations.

The EC220 built upon the EC210’s strengths, boasting a 32% increase in productivity while maintaining comparable fuel usage. Its higher output makes it suitable for heavy-duty tasks like bulk excavation and materials handling. According to Watz, “The EC220 delivers high return where speed and volume matter without compromising efficiency.”

EC360: Bigger Isn’t always better

Outpaces larger rivals in productivity and efficiency, even at reduced RPM.

The heavyweight EC360 surprised testers by outmatching larger-class competitors. Despite running at a fuel-saving 1,500 RPM, it achieved up to 25% higher productivity and 21% greater fuel efficiency compared to competitors operating at peak RPM. “This model proves that thoughtful design can outperform brute force,” noted Watz.

Smart design, safer sites

From ROPS cabs to enhanced visibility, safety is built in from the ground up.

Safety features were a key differentiator. Volvo was the only OEM to offer a ROPS-certified cab as standard. Added elements like deck lighting, slip-resistant surfaces, smartly placed handrails, and a built-in rear-view camera highlighted the brand’s operator-first approach. Test operators praised visibility and ergonomic layouts that reduced fatigue over long shifts.

Serviceability with uptime in mind

Ground-level access, smart layout, and maintenance-friendly features keep jobs moving.

Ease of maintenance also played a role in Volvo CE’s top scores. Features like a smaller engine hood, improved ground-level access to service points, and anti-clog track holes make daily upkeep simpler and faster — critical in the demanding environments of the Middle East and Africa.

These real-world trials not only reaffirm Volvo CE’s engineering direction but underscore its ability to deliver reliable, cost-effective solutions that meet the region’s harsh worksite demands.

Beneath the lively streets of Cairo, a technically ambitious infrastructure project is taking shape with the construction of the new Giza Station on Metro Line 4 – set to be one of the deepest metro stations in North Africa, reaching depths of up to 81 m.

Orascom Construction PLC has tasked BAUER EGYPT S.A.E., a subsidiary of BAUER Spezialtiefbau GmbH, with carrying out specialist foundation engineering works. Construction began in November 2024 and is scheduled for completion by December 2025.

Two special foundation techniques are in use: approx. 49,000 m² of diaphragm walls and 7,400 m² of barrettes, some reaching 81 m in depth.

A BAUER MC 96 duty-cycle crane is being deployed in double shifts, six days a week.

As of May 2025, 84 out of 209 diaphragm wall panels have been completed. The full station will span around 5,543 m².

“At this size and depth, there’s zero tolerance for deviation – every centimetre counts,” said Karim Galal, project manager at Bauer Egypt.

“The BAUER Construction Process provides us with a clear structure and guidance. It ensures that everyone involved in the project works to the same standards and helps us achieve our goals on time.”

Tight space and coordination constraints mark this project. Parts of the site are still in use until November 2025 to backfill an existing tunnel, allowing for further excavation.

“We’re working under highly unusual conditions with extremely tight space and immense time pressure,” Galal said. Notably, the tunnel boring machines are operating one above the other, a first in Egypt.

“The logistics, the depth, and the constant coordination with other trades present daily challenges, but that’s exactly what makes this project so special,” added Galal. The foundation engineering phase is expected to wrap up by year-end, paving the way for a significant upgrade to Cairo’s urban mobility.
