Hello,
IMO GHG reduction requires 40% reduction in CO2 emissions per transport work by 2030, compared to 2008 levels. Can someone shed some light how to determine the 2008 baseline.
Thanks.

Hello @Mhaque,
If I am not mistaken, the baseline of 2008 arises from the “Third IMO Greenhouse Gas Study 2014”.
The bottom-up method used in this study is similar to the approach taken in the Second IMO GHG Study 2009 for estimating emissions based on activity. This method involves gathering detailed data from specific vessels or fleets to estimate greenhouse gas emissions. By focusing on the operational characteristics and fuel consumption of these vessels, the bottom-up approach provides a more accurate assessment of emissions compared to broader methods.
Unlike previous analyses that relied on ship type, size, and annual average activity, this study calculates activity, fuel consumption (per engine), and emissions (per greenhouse gas and pollutant) for each in-service ship every hour from 2007 to 2012. This data is then aggregated to determine the totals for each fleet, as well as for total shipping (including international, domestic, and fishing) and international shipping. This approach eliminates uncertainties related to average values and significantly improves the detail of shipping activity, energy demand, and emissions data.
It is worth to mention that there are currently no agreed figures within the IMO for the annual
life cycle GHG emissions at the 2008 baseline (this is expected to be discussed within the IMO in the future).
The Third IMO GHG Study is also referenced in the Initial IMO GHG Strategy (resolution MEPC.304(72))
