Я тут, понимаешь, пытаюсь изо всех сил развенчать устойчивые негативные стереотипы, сложившиеся в обществе вокруг британских учёных, а они... 
Цитата:
Additional workings
1 ‘Over 64 million unnecessary emails sent by Brits every single day’
- UK population of 52,351,213 adults (18 and over. Source: ONS)
- 87% of adults use the internet daily and 86% of all adults use email (Source: ONS)
- 86% of 52,351,213 = 45,022,043
- According to Censuswide research, Brits send an average of 11.29 unnecessary, unactionable emails in an average week. Rounding this to 10, we can calculate the following:
- 10 emails each per week x 45,022,043 email-using population = 450,220,430 unnecessary emails sent by Brits every week
- Divided by 7 = 64,317,204 unnecessary emails sent by Brits every day
2 ‘81,152 flights to Madrid’
- Distance to madrid one way = 1,250km (Webflyer.com - Heathrow to Madrid)
- Carbon per km average short haul flight = 0.162kg CO2e/km (BEIS emissions factors for average short haul flights - aircraft emissions + high altitude factors only)
- 0.162kg CO2e/km x 1,250km = 202.5kg CO2e per one way flight to Madrid
- = 0.2025 tonnes CO2e per one way flight to Madrid
- (0.2025 tonnes CO2e / 16,433.23) x 1000 = 81,151.90
- Number of one way average class passenger flights to Madrid saved = 81,152
3 ‘3,334 diesel cars off the road’
- Estimated annual mileage per diesel car in England in 2018 = 9,400 miles. (Source: National Travel Survey NTS0901)
- Carbon per mile for average diesel car (exhaust pipe + fuel supply chains + embodied carbon in the car) = 0.5243kg CO2e/mile
- 9,400 miles x 0.5243kg CO2e/mile = 4928.42kg CO2e carbon per car per year
- Carbon per car per year = 4928.42kg CO2e
- Carbon per car per year = 4.92842 tonnes CO2e
- Carbon saved per year by population each reducing email traffic by 1 emails per day = 16,433 tonnes
- 16,433 tonnes / 4.92842 tonnes CO2e = 3,334.33
- Diesel cars off the road per year = 3,334
4 ‘64 million unnecessary emails sent every day is contributing 23,475 tonnes of carbon a year’
- 64,317,204 unnecessary emails sent by Brits every day
- x1 email = 1g carbon = 0.000001 tonnes CO2e per email (Source: Mike Berners-Lee)
- 64,317,204 x 0.000001 = 64.317 tonnes CO2e per day
- 64.317 x 365 = 23,475.779
- = 23,476 tonnes CO2e per year
5 ‘Brits sending 1 less email a day would save 16,433 tonnes of carbon a year’
- x1 email = 1g carbon = 0.000001 tonnes CO2e per email (Source: Mike Berners-Lee)
- 365 days per year / 12 months = 30.417 emails per mon
- 0.000001 tonnes of CO2e x 30.417 emails per month x 12 months per year = 0.000365004 tonnes CO2e saved per person, per year
- UK population of 52,351,213 adults (18 and over. Source: ONS)
- 87% of adults use the internet daily and 86% of all adults use email (Source: ONS)
- 86% of 52,351,213 = 45,022,043
- 45,022,043 adults x 0.000365004 tonnes of carbon saved per person per year = 16,433 tonnes of carbon saved per year by total UK population
