| Visited conferences
div.alert.alert-info
p.
This page gives an overview of the conferences, workshops, and summer schools I have visited together with the #[strong travel carbon footprint].
The #[strong accomodation] I used is also listed, but not included in the carbon footprint.
The calculation is based on averages from #[a.alert-link(href='https://ourworldindata.org/travel-carbon-footprint', target='_blank') Our World in Data].
p.
For #[strong biking], I counted 30 g CO#[sub 2] / km as a rough estimate based on my diet.
#[strong Flights] shorter than 500km are counted as 'domestic' (255 g / km), otherwise they are counted as short/long-haul (averaged on 153 g / km).
#[strong Trains] in the Netherlands probably emit less than the estimate from Our World in Data because #[a.alert-link(href='https://www.ns.nl/over-ns/duurzaamheid/fossielvrij', target='_blank') the NS runs on wind energy].
p.
The carbon footprint per capita of the Netherlands was #[strong 9.66] t in 2017 (26,448 g / day), according to #[a.alert-link(href='https://ourworldindata.org/co2/country/netherlands?country=NLD~DEU~DNK~SWE~FRA~BEL', target='_blank') Our World in Data].
The global average was #[strong 4.79] t in 2016 (13,114 g / day), according to #[a.alert-link(href='https://www.worldometers.info/co2-emissions/co2-emissions-per-capita/', target='_blank') Worldometer].
p.
Transport, aviation, and shipping #[a.alert-link(href='https://ourworldindata.org/grapher/ghg-emissions-by-sector?time=latest&country=~NLD', target='_blank') make up 34% of emissions in the Netherlands].
For the average Dutch person this is #[strong 3.28] t per year or #[strong 8,992] g per day (but note that this includes more than personal travel).
Worldwide, we have #[a.alert-link(href='https://ourworldindata.org/emissions-by-sector#transport-16-2', target='_blank') 16.2% of emissions from transport], which makes this figure #[strong 0.78] t per year or #[strong 2,125] g per day per capita.
p.
Please let me know if you think some of the calculations can be improved!
