Below are the EFs we used, indicating the specific emissions per mode of transport:
• 20gCO2/tkm for Barge transport (Source: GLEC 2020)
• 0.1gCO2/tkm for Gas pipeline transport (Source: Russ & Schuler 2017)
• 7.3gCO2/tkm for Fuel pipeline transport (Source: Choquette-Levy et al. 2018)
• 20gCO2/tkm for Rail transport (Source: GLEC 2020)
• 50gCO2/tkm for Truck transport (Source: GLEC 2020)
While recognizing that emissions attributed to pipeline transport are the largest in magnitude for the various modes
of transport, we note this is due to the substantially larger quantity and distance over which the commodities were
transported. Below is a summary of the Group’s transports emissions during 2020.

In all other cases, the barges emissions are included in the vessels emissions
There remains some uncertainty in the emission estimates as a result of the variability of recognized emission
factors in the published literature. Further industry consolidation toward agreed upon best-practices, or additional
information from the transport operators may reduce this uncertainty.
We recognize the impact of CO2 emissions upon the climate, and are seeking to develop mechanisms as part of our
business strategies to more explicitly account for these impacts.
The emissions related to vessels, both chartered and fully-owned, were 40% lower in 2020 relative to 2019. This
reduction was largely due to the pandemic-driven impacts upon global trade flow. Mercuria anticipates that as
global trade recovers there is a substantial likelihood that commodity movements will return to pre-pandemic levels
or potentially even higher. This highlights the variant nature of our business activity and necessity to look at trends
over time rather than over-assess a single year’s data.
