New Technology Can Reduce Toxic Emissions In UK’s London Cabs

16 percent of nitrogen oxide (NOx) emissions in central London are caused by taxis. They are also responsible for 26 percent of the particulate matter in central London’s air. Both emissions come with a bevy of hazards to human and environmental health. However, a German company called HJS has developed a solution: a Selective Catalytic Reduction (SCR) system that can be retrofitted to old taxis. If the system works as advertised, taxi engines will not only be cleaner, but they will last longer and reduce costs.

SCR Does Not Affect Performance

According to HJS, the system that they hope to install in London cabs does not impact their performance or engine control unit. It works independently from the engine to remove nitrogen oxides and other contaminants from the exhaust. HJS estimates that SCR will reduce NOx by 75 percent compared to Euro 5 diesel taxis. This means that, by adopting an SCR system, Euro 5 taxis can become Euro 6.

Euro 5 Versus Euro 6

There are approximately 4,400 cabs in London with Euro 5 certification. Euro 5 denotes a vehicle whose engine emissions are higher than ideal – 0.18 g/km of NOx to be exact (for diesel). In comparing cars by their eco-friendliness, those that are certified Euro 6 win by a landslide. Euro 6 vehicles with diesel engines must emit no more than 0.08 g/km of NOx. If all outdated taxis were to adopt SCR, the entire fleet of London cabs would operate at an acceptable emissions level. For this to happen, the technology would likely need government approval.

Lifespan Extension On London Taxis

London law states that, starting in 2022, Euro 5 taxis will be forced to retire after 12 years of operation. This is where the Euro 6 advantage for taxi companies and drivers is most palpable. Cabs that have Euro 6 certification can drive for 15 years before retirement. That’s three extra years. A lot of fares can be collected in three years, and a lot of money can be saved on taxis if the old ones can be replaced every 15 years instead of every 12. SCR is, therefore, a cost-effective technology that should benefit the drivers themselves. Hidden costs, of course, may remain.

If SCR is approved and implemented, it could signal the end of energy-inefficient taxis – not only in London, but the world over. Electric power will claim whatever vehicles SCR misses. Diesel cabs are just another casualty in the war for sustainability.

MADISON, Wis— Evo Tech announced new updates to its flagship platform, Evolution AI, designed to enhance threat detection and real-time data analysis for intelligence, security, and law enforcement agencies. The upgraded system introduces expanded capabilities in pattern recognition, automated alerts, and data aggregation to improve response accuracy in critical operations.

The company’s latest release focuses on enabling faster identification of potential threats across multiple data streams, including text, imagery, and audio inputs. By combining adaptive machine learning models with advanced verification tools, Evolution AI now provides a more precise and scalable method for detecting irregular or suspicious activity.

“Security challenges are growing more complex as data sources multiply,” said Maria Pulera, Evo Tech’s representative. “Our goal with these new features is to help agencies detect threats earlier and reduce the time between data discovery and action. These tools are built to support real-world decision-making in fast-moving environments.”

Among the new enhancements are:

Automated Threat Classification: The platform can now categorize potential risks based on severity and relevance, allowing analysts to prioritize investigations more effectively.
Cross-Platform Data Fusion: Evolution AI aggregates data from both structured and unstructured sources, presenting analysts with unified, real-time insights across visual, audio, and textual inputs.
Adaptive Anomaly Detection: Using machine learning, the platform learns from historical data to recognize unusual activity patterns and flag potential security concerns automatically.
Enhanced Visualization Tools: New dashboard designs allow users to view correlations, track trends, and monitor data sources simultaneously with improved clarity.

Evo Tech’s development team designed these upgrades to help intelligence and defense organizations address increasing information volume and data fragmentation. According to industry reports, global data generation is expected to exceed 175 zettabytes annually by 2026, underscoring the need for advanced analytical tools that can handle large-scale, multi-format data securely.

Pulera added, “Our technology aims to reduce the manual burden on analysts while maintaining the highest standards of data integrity. We’ve focused on features that allow agencies to operate more efficiently without compromising security.”

The company’s engineering team also confirmed that Evolution AI’s infrastructure supports deployment in secure, private networks, aligning with the data protection requirements of defense and intelligence clients. Evo Tech plans to continue rolling out additional modules throughout 2025, with a focus on multilingual data analysis and predictive threat modeling.

Evo Tech’s latest updates come as governments and private institutions invest heavily in AI-driven security technologies. Market forecasts from MarketsandMarkets estimate that AI in defense and security applications will surpass $13 billion by 2028, reflecting a growing global emphasis on automation and early threat detection.
