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 If all outdated taxis were to adopt SCR, the entire fleet of London cabs would operate at an acceptable emissions level.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.

A sea of confusing technical terms and threats surround people today. Many feel lost, unsure of how to protect themselves online. A distinguished cybersecurity and technology expert, Dr. Dave Chatterjee is teaching people how. He has practiced information technology management since 2001. In this field, which often bewilders outsiders, he combines academic knowledge with practical insights.

About Dr. Dave Chatterjee

The tech figure authored “Cybersecurity Readiness: A Holistic and High-Performance Approach,”  which Sage published and readers praise for its thorough and accessible take on cybersecurity preparation. 

Additionally, respected publications like USA Today, The Wall Street Journal, and the Massachusetts Institute of Technology (MIT) Sloan Management Review have recognized his work.

“Communicating complex cybersecurity concepts clearly and effectively is essential,” Dr. Dave Chatterjee explains. “I aim to connect technical know-how with practical understanding, making sure important cybersecurity messages reach and impact all stakeholders, from executives to information technology (IT) staff.”

Dr. Dave Chatterjee has received numerous accolades throughout his career. These include the Outstanding Executive Master of Business Administration Professor of the Year award. He has also been named a University of Georgia (UGA) Outstanding Teaching Faculty Honoree. 

Before the pandemic, Dr. Dave Chatterjee launched his Technology Roundtable. It features distinguished business leaders, award-winning chief information officers, and other renowned thought leaders. The roundtable covered topics such as blockchain, artificial intelligence, data quality, and cybersecurity.

Aside from his professional pursuits, he is also passionate about youth development. He also engages in science, technology, engineering and mathematics (STEM) initiatives, offering professional development workshops to K-12 students on topics ranging from making the most of collegiate experiences to safe and responsible use of technology. He also provides summer research opportunities for outstanding high school students, mentoring the next generation of cybersecurity professionals.

Decoding Cybersecurity for All

Dr. Dave Chatterjee believes effective cybersecurity involves people as much as technology. He stresses creating an organization’s security-aware culture, starting with clear, straightforward communication.

“Cybersecurity affects every part of an organization,” Dr. Dave Chatterjee states. “We create a shared sense of responsibility and preparedness by explaining complex ideas in relatable ways.”

This philosophy is evident in his roles, including his position as an adjunct associate professor at Duke University and his past work as a professor at The University of Georgia’s Terry College of Business. His skill in explaining technical concepts has made him a popular speaker and advisor across many industries.

The Power of Clear Communication in Cybersecurity

Clear communication in cybersecurity is non-negotiable. As cyber threats become more complex, explaining security concepts clearly and concisely helps organizations better protect themselves.

“Clear communication forms the foundation of a strong cybersecurity strategy,” Dr. Dave Chatterjee emphasizes. “It allows cybersecurity professionals to work with other departments, identify and reduce potential risks, respond well to incidents, and follow regulations and standards.”

This matters especially now, as cybersecurity has become a top priority for company boards. With experts expecting global cybercrime costs to reach $10.5 trillion by 2025, clear explanations of cyber risks and protection strategies help leaders make informed decisions.

Bridging Technology and Human Understanding

Dr. Dave Chatterjee does more than explain technical ideas. He promotes a better grasp of how people factor into cybersecurity, knowing that even the best security systems can fail due to human error or lack of awareness.

His Cybersecurity Readiness Podcast Series has over 70 episodes and listeners in 105 countries. It offers thought-provoking, jargon-free discussions on improving cybersecurity. These discussions cover strategies for individuals, organizations, and nations. This effort shows his advocacy for making cybersecurity knowledge available worldwide.

“The podcast series creates a community where experts, leaders, and practitioners discuss cybersecurity challenges and opportunities,” he notes. “These conversations help build a more informed and resilient digital ecosystem.”

Making Cybersecurity Less Intimidating  

With new technologies like artificial intelligence and quantum computing bringing new challenges and possibilities to cybersecurity, concise communication becomes even more critical.

The tech professional continues to adapt his work in this area. A recent USA Today article, “Dave Chatterjee Drops the Cybersecurity Jargon, Encouraging Proactiveness Rather than Reactiveness,” highlights his ongoing effort to make cybersecurity accessible and actionable for everyone.

“The future of cybersecurity depends on our ability to communicate well across all levels of society,” he concludes. “Promoting a shared understanding of cyber risks and best practices creates a more resilient digital world for everyone.”

The battle for digital security requires more than just advanced technology. It demands clear communication. Dr. Dave Chatterjee’s talent for translating cybersecurity concepts into accessible language turns technical knowledge into practical action. 

Undeniably, Dr. Dave Chatterjee’s gift for clarity will remain invaluable, helping create a more secure digital future for everyone.
