[Green Car Congress] New research published today (23 May) in Scientific Reports has found a marked and progressive 80% decline in atmospheric CO (carbon monoxide) in SE England since 1997, following adoption of strict controls on gasoline vehicle emissions begin[ning] in the 1990s. The decline is strongest (approximately 50 ppb per year) in the 1997–2003 period but continues post 2003.
The successful reduction of carbon monoxide in the UK is also matched by high percentage reductions across Europe over the same time period. This suggests that recent rises of carbon monoxide in newly developed countries can be reversed in a 20-year time frame with similar technological and policy implementations. The open-access study is published in the journal Scientific Reports…
