Energy Consumption and Emissions
Emissions from combusting marine fossil fuels in internal combustion engines in 2018 amounted to 1,735,597 tCO2 representing 99.5% of our Scope 1 emissions (HFO / MGO / LO Marine fuel and escape / use of refrigerants).
Scope 1 plus Scope 2 (from use of commercial electrical power) gave a total of 1,744,680 tCO2 emissions from CNCo’s operations.
Scope 2 emissions are immaterial in relation to our Scope 1 emissions (0.024%) and contributed 423.8 tCO2 to the figure above.
Scope 3 emissions from shore and crew air travel contributed 5,822 tCO22 which is a low contributor (0.333%) to total GHG footprint.
The overall emissions figure for Scope 1 and 2 increased by 20.7% on the prior year and is directly reflective of the increase in our fleet size by 21.3%.
We also measure emissions of SOx, NOx, Particulate Matter (PM) and Volatile Organic Compounds (VOCs). As they are related to Scope 1 emissions, their numbers have been fluctuating accordingly with an average of 20% increase on 2017 figures.
A summary of all these figures are presented in the Environmental Summary report.
Climate Change and Our Business
Eight new vessels are being constructed to allow fleet expansion and tonnage renewal for both the Mihos and Challenger fleets. Designed by SDARI – China’s leading ship design house and built in Guangzhou Wenchong shipyard – these vessels will be our largest new-buildings in terms of container capacity and deadweight. Four of these are 2350 TEU vessels with deadweight tonnages (DWT) of 30,450, and the other four are 2750 TEU vessels at 33,600 DWT.
These pure container vessels feature a modern integrated bridge design and will be delivered with VSAT capability. Internet connectivity allows for additional technical support and easy communication for our seafarers while at sea.
The vessels will have an enhanced cargo capability in holds number 3 and 4, which will have cell guide stoppers and strengthened tank tops that enables use in multiple roles. The pontoon hatch covers have been additionally strengthened to allow for project cargo to be carried on deck.
Considerable effort has been made to reduce power consumption in all areas of the ship. The hull shape is optimized for fuel efficiency and LED lighting is fitted throughout the ship to provide energy efficient illumination.
Open loop hybrid-ready scrubbers are on order to be installed to comply with the 0.5% sulphur limit which comes into force on 1st January 2020. Hybrid scrubbers provide the flexibility, with some modifications, to operate in a closed loop.
The ship's larger capacity and smaller footprint will broaden deployment opportunities within Swire Shipping’s main trading areas.
We look forward to receiving the first vessel, MV Changsha, in late 2019. The remaining vessels, MV Chefoo, MV Chekiang, MV Chengtu will be delivered between late 2019 and 2020.
