Temtop Test Part 3 – following on from two highly viewed videos I did last year

Six months on from the expansion of ULEZ (Ultra Low Emission Zone) to cover the whole of London, in August 2023 and the London Mayor still hasn’t released impact data to prove that it’s improved the air quality in the expanded zones. And it won’t be released until after the elections in May 2024. However, I shot two videos last year, taking an ELITECH Temptop air quality meter around London, covering firstly the previous ULEZ zone in part 1 and the proposed area of expansion in Part 2. This means I can directly compare my findings today, six months on from the expansion to the data I had before, to see if there has been any improvement in air quality. This is what I do in this video. And the results may surprise you – they certainly astonished me!
