According to IMO's statistics, shipping accounts for 80% of global trade and emits over 1 billion tons of CO2 into the atmosphere every year, accounting for about 2.9% of the CO2 emissions worldwide. The shipping industry plays an important role in reducing global carbon emissions. In recent years, the UN Climate Change Conference and EU have called for the control of global warming at 1.5°C, and many international initiatives and organizations have encouraged enterprises to set reduction targets and measures in response to the goal of net-zero emissions by 2050.

Energy Saving Strategies
Operational Scope  Energy Conservation Strategies 
Onshore business locations 
  • The Company has used electric motorcycles as company vehicles and replaced existing company cars with hybrid electric vehicles (about 235 liters of gasoline and 0.533 tons of CO2e are saved if the average annual mileage is about 10,000 kilometers).
  • Using water chiller units of different tons for the central air conditioner in the building based on seasonal and temperature requirements and setting up the auto power-on time of the air-handling unit on each floor and the frequency converter for automatic input regulation according to needs.
  • Adoption of energy-efficient LED lighting equipment, zoning lighting, and induction lights.
  • Prioritized purchase of products with a Level 1 energy label.
  • Turning off lights during 13:00-13:30 after having lunch (except for special needs that require the use of lights).
  • Turning off air conditioners, lights, and equipment in empty spaces in the office (such as conference rooms or office spaces not in use).
  • Setting up programs for group control of elevators, where the elevators will enter sleep mode when not in use for 10 minutes for energy saving.
  • Setting up the water dispensers on each floor to automatically keep them in sleep mode from 23:00 to 06:00 on weekdays and all day on weekends.
  • Setting up printers in power saving mode to have them automatically enter power saving mode when not in use for a period of time.
  • Setting up office computers in power saving mode to have them automatically enter low-power-consuming sleep mode after not in use for 5-10 minutes.
Container yard
  • Implementation result of newly purchased electric machinery and equipment: In 2023, 2 new electric gantry cranes were put into operation to replace the old ones, 2 electric and 1 dieselpowered. The electricity consumption of the new electric gantry cranes totaled 18,698 kWh. Compared to the average annual electricity consumption of the old ones over the 3 years before the renovation, which was 117,364 kWh, 98,666 kWh of electricity was saved per year on average. The diesel-powered gantry crane used an average of 93,422 liters of diesel per year, and after the replacement, a total of about 296.0548 tons of CO2e had been reduced.
Reefer containers 
  • Inverter compressor models are added to the existing reefer containers, and the utilization rate has increased from 3% in 2021 to 15% in 2023.
Fleet 
  • Implementation of SEEMP Part I/II/III to promote the effective use of fuels and prepare records as per laws in order to save energy and reduce carbon emissions.
  • Smart Ship Center - Monitoring with the Green Shipping Module.
  • Determination of optimal routes with weather routing systems.
  • Foundation of the CII Task Force in 2022 to pay attention to the actions and regulations of international organizations such as the International Maritime Organization (IMO).
  • Sailing with ultra-low speed in line with the sailing schedule to save energy and reduce carbon emissions.

Note: Energy intensity reduced by 5.77% compared to 2022

Management of the Fleets' Carbon Emissions

Yang Ming continues to go above and beyond international regulatory requirements by adopting management measures such as hull optimization, the introduction of new eco-friendly ships, optimal ship speed control, the use of smart monitoring systems, and the modification of existing ships. The carbon intensity of the operating ships in 2023 was 37.90 g/teu-km, reducing by 61.86% compared to 2008, early attaining IMO's goal of a 40% reduction by 2030.

Carbon Intensity Performance of the Fleet
Although the fleet's carbon emissions in 2023 were 102,194.7764 (tons CO2e) higher than that in 2022, the carbon intensity was reduced by 2.31 g/TEU-km, showing a 5.74% improvement, thanks to the fact that the unit transport volume in 2023 was higher than that in 2022.

COUNTERMEASURES

The IMO approved the new “Energy Efficiency Existing Ship Index (EEXI)” and “Carbon Intensity Indicator (CII)” regulations at the MEPC 76 meeting held via video conference from June 10 to 17, 2021, which will take effect on January 1, 2023. For the IMO’s strategies to reduce the GHG emissions of vessels, on the technical aspect, the EEXI is adopted; on the operational aspect, the CII is adopted. By calculating the “EEXI” and “CII,” correction plans are developed for vessels with poor performance, and the vessels are included in the SEEMP. 
 

The following are the measures adopted by the Company in response to the EEXI and CII:
Issue/Regulation Description and Planning Energy Efficiency Existing Ship Index (EEXI) 
EEXIs must be submitted to Classification Societies for recognition for international energy efficiency certificates (IEEC, for one-time verification like EEDI). 
Carbon Intensity Indicator (CII) 
Ships' annual CII values must be calculated annually and reported. The ships are rated from A to E based on their performance every year. If any vessel is rated D for 3 consecutive years or E in one year, correction plans must be developed.
Suggested Improvement Methods from Classification Societies 
  • Shaft/main engine power limitation
  • Conversion of fuels into lowcarbon fuels or installation of energy saving devices
  • Hull optimization (hull cleaning/coating)
  • Propulsion system (electric, new energy-efficient) (ESD) energy efficiency management
  • Fleet management and logistics planning (weather routing/waste heat recovery system/improved logistics)
  • Sailing optimization
  • Ship speed control
  • Fuel replacement (alternative fuel)
Yang Ming’s Practices 
  • Installation of energy saving equipment and energy-efficient modifications on existing ships: 100% EPL modification rate: Reducing the maximum output horsepower of engines, limiting the engine revolution and horsepower output, to reduce the fuel consumption.
  • Installation of energy saving equipment and energy-efficient modifications on existing ships:
    • Energy-efficient modifications are made to the bulbous bows on ships in the fleet to reduce vessel resistance.
    • Energy-efficient modifications are made to the propellers on ships in the fleet. 
  • With the Smart Ship Center (SSC), each vessel's status can be checked in a real-time manner, and data analysis is also available, which not only reduces maritime risks, but also help enhance vessel energy efficiency management.
  • The use of weather routing helps:
    • Optimize routes and shorten sailing time.
    • Maintain relatively stable power output according to sailing schedule requirements and allow speed and RPM to fluctuate properly under different weather conditions, reducing unnecessary fuel consumption.
  • 19 fuel saving measures are adopted, and AI is used to gather the locations of ships through GPS and calculate the actual route distance accurately. 
  • Hull cleaning: Formerly ships aged 10 years or more needed to be cleaned once every 5 years, but now they must be cleaned every 2.5 years to reduce fuel consumption to improve efficiency.
  • For ships, we plan to use biofuel that complies with the ISCC (International Sustainability & Carbon Certification) process certification to replace traditional oil. We expect that this can reduce well-to-wake carbon emissions by about 20% compared to traditional fuels.
The EEDI of the Company's new building ships are better than that specified by the applicable regulations, and all of the ships are EEDI certified. The management practices mentioned above are compliant with regulatory requirements and undergo an external audit annually.

GHG INVENTORY

Yang Ming has actively promoted green shipping. In 2021, the Company introduced the ISO 14064-1 GHG inventory and acquired third-party verification. Based on the inventory results, we have promoted and planned the setting of GHG emission reduction targets and measures for the Company. The Company continues to complete the ISO14064-1 GHG inventory for the ships owned and operated by the Company every year, and has introduced the GHG Protocol Corporate Standard, been certified to ISO 14064-1 and the GHG Protocol, and obtained certification from the Taiwan Accreditation Foundation.
