A Very intriguing article by
SIEMENS talking about when we changed the way we travel and how it impacted the global CO2 Emissions. According to
OurWorldinData.org just in 2018, 8 Billion tonnes of CO2 were emited, in which the Transportation occupied a heavy 24% of total CO2 emissions from Energy. From such big numbers, 74.5% of such emissions came from road vehicles (45,1% from cars, motorcycles, busses and taxis, and 29.4% from trucks and lorries.)
Being quite an important part of the global CO2 emissions, even to this day, the
SIEMENS article describes how our methods of transportation evolved, starting from 1830 zero emission sailing boat, taking 5-6 weeks for a trip between UK to Canada to our current speeds of a 7.5h flight and it's CO2 emissions
As we can see by the data from 2018 UK Department of Business, Energy and Industrial Strategy, this histogram presents the amount of grams of carbon dioxide emitted for each passengers kilometer used on such transport method.
A bit on the Global Warning subject: there is a risk of a 1,5C degree increase by the year 2050 due to Global greenhouse gas emissions. In order for us to reach the net zero global emission and avoid passing the 2C degree irreversible threshold, a 20% reduction in emission is required.
