| Zusammenfassung |
| This paper presents 5 km×5 km Arctic emissions inventories of important
greenhouse gases, black carbon and other pollutants under existing and
future (2050) scenarios that account for growth of shipping in the region,
potential diversion traffic through emerging routes, and possible emissions
control measures. These high-resolution, geospatial emissions inventories
for shipping can be used to evaluate Arctic climate sensitivity to black
carbon (a short-lived climate forcing pollutant especially effective in
accelerating the melting of ice and snow), aerosols, and gaseous emissions
including carbon dioxide. We quantify ship emissions scenarios which are
expected to increase as declining sea ice coverage due to climate change
allows for increased shipping activity in the Arctic. A first-order
calculation of global warming potential due to 2030 emissions in the
high-growth scenario suggests that short-lived forcing of ~4.5
gigagrams of black carbon from Arctic shipping may increase global warming
potential due to Arctic ships' CO2 emissions (~42 000 gigagrams)
by some 17% to 78%. The paper also presents maximum feasible reduction
scenarios for black carbon in particular. These emissions reduction
scenarios will enable scientists and policymakers to evaluate the efficacy
and benefits of technological controls for black carbon, and other
pollutants from ships. |
