We are proud to share that Critical Mass: The One Thing You Need to Know About Green Cars has been named a 2026 Independent Press Award Winner. 

In an era where climate change dominates global discussion, Critical Mass sees Felix our CEO, Nick Molden and Felix Leach unpack the complexity of vehicle emissions with clarity and rigour. Building on insights from Felix’s previous work, Racing Toward Zero, the book tackles the often-confusing landscape of automotive pollution by asking a deceptively simple question: what single piece of information best captures the true environmental impact of cars? 

We are delighted to share that Emissions Analytics and Oxford Indices, founder and CEO, Nick Molden, has been admitted as a Fellow of the Royal Society of Chemistry (FRSC).

Fellowship is awarded to those who have made an outstanding contribution to the chemical sciences. Nick’s admission recognises his pioneering work to expand the boundaries of real-world environmental testing, particularly in relation to vehicle emissions, tyre wear particles and indoor air quality.

A surprisingly compelling subject
Dinner table, or social media, conversation may centre on arguments over which football team deserves to win the league, or whether the Mustang or Camaro is better, but the common feature of such polemics is that they represent simple and interesting questions. The topic of tyres, however, and if you dare raise it, may stun your companions into silence. Tyres are not simple and interesting. They are complex and boring – at least on the outside.
