| Zusammenfassung |
| Most atmospheric scientists agree that greenhouse gas emissions have already
caused significant changes to the global
climate system and that these changes will accelerate in the near future.
At the same time, atmospheric scientists who – like other scientists – rely on international
collaboration and information exchange travel a lot and, thereby, cause substantial emissions of CO2.
In this paper, the CO2 emissions of the employees working at an atmospheric research
institute (the Norwegian Institute for Air Research, NILU) caused by all types of
business travel (conference visits, workshops, field campaigns, instrument maintainance, etc.)
were calculated for the years 2005–2007.
It is estimated that more than 90% of the emissions were caused by air travel, 3%
by ground travel and 5% by hotel usage.
The travel-related annual emissions were between 1.9 and 2.4 t CO2 per employee or
between 3.9 and 5.5 t CO2 per scientist.
For comparison, the total annual per capita CO2 emissions are 4.5 t worldwide, 1.2 t
for India, 3.8 t for China, 5.9 t for Sweden and 19.1 t for Norway.
The travel-related CO2 emissions of a NILU scientist, occurring in 24 days of a year
on average, exceed the global average annual per capita emission.
Norway's per-capita CO2 emissions are among the highest in the world, mostly because
of the emissions from the oil industry.
If the emissions per NILU scientist derived in this paper are taken as representative for
the average Norwegian researcher, travel by Norwegian scientists would nevertheless account
for a substantial 0.2% of Norway's total CO2 emissions.
Since most of the travel-related emissions are due to air travel, water vapor emissions,
ozone production and contrail formation further increase the relative importance of
NILU's travel in terms of radiative forcing. |
