Providing a quality service that delivers goods safely and punctually to the destination port while taking environmental protection, energy conservation and reduction in GHG emissions in account have been the longstanding principle and goal of Evergreen Marine. A variety of business management measures, reduction strategies and improvements in marine design have been employed by the Evergreen fleet to reduce the energy consumption of our ships. A new generation of green ships is also being introduced to do our part of protecting the Earth's environment through the reduction of pollution and GHG emissions. IMO statistics indicated that CO2 emissions from the shipping industry accounted for 2.7% of all primary global GHG emissions. If left unchecked, this ratio may grow to 15% by 2050. In response to global trends, green shipping is now being developed by Evergreen Marine and CO2 reduction targets have been set. A 40% reduction in CO2 emissions by 2030 is planned with 2008 as the baseline. In 2050, the carbon dioxide emission rate is planned to reduce by 70% and the total greenhouse gas emissions to be reduced by 50%.
The efforts made by Evergreen Marine towards fuel consumption, GHG emissions and continuous energy reduction/carbon reduction are reflected in the annual decreases in marine fuel consumption. Our fleet's CO2 emissions have continued to decrease as well. Our total emissions in 2019 were 36.9% (61.46g/TEU-KM) lower than 2008.
CO2 Annual Emission
To fulfill our commitment to environmental protection, Evergreen Marine tracks and analyzes the energy consumption of our ships to improve their energy efficiency. High-efficiency operations are conducted to realize the goals of energy conservation and carbon reduction. At the same time, the latest maritime weather navigation system is used by Evergreen Marine to provide our ships with the safest and most fuel-efficient routes in order to minimize fuel consumption, save energy and reduce carbon emissions. Each ship is also equipped with a certified ship stability computing system that quickly calculates the optimal trim, draft, weight-distribution and hull stress distribution for any kind of loading. Optimal propulsion efficiency can then be assured without compromising on safety.
The optimization of docking procedures reduces the demands on the main engines, and lowers fuel consumption. The use of slow steaming means one turbo-charger can be switched off to reduce the power output from the main engine by one-third, greatly reducing the amount of CO2 emissions over the same route. All of our fleet including leased ships are fitted with the weather navigation system. Captains can then select the shortest and safest route at sea to avoid bad weather and reduce unnecessary drag. Ship crews also actively turn off unnecessary lighting and pumps to reduce fuel consumption and CO2 emissions from the ship's generator.
Ship information such as fuel consumption, route, bunker/water tank level and payload are sent back to our offices for analysis every day via satellite transmission. We also ask our ships to minimize the amount of ballast water in order to reduce the weight of their ships, reduce the amount of fuel needed for ship propulsion and improve energy efficiency
Two key measures have been adopted for emission reduction, the first being staying in contact with the shipping registry. An implementation guide for compliance with EU MRV requirements has now been developed that can be used for future auditing and verification activities. The second is training to understand EU MRV requirements, develop implementation guides and monitoring plans, as well as implement the monitoring and reporting requirements. Existing data monitoring and analytical methods were assessed to determine if they satisfied the requirements so that the appropriate measure can be put into place. A system for collecting the data required by MRV regulations could then be developed to build a data-collection platform. These measures not only help prepare for the implementation of MRV regulations but also provide an accurate electronic record of our own operational data. The data can be used to facilitate centralized management and analysis of fleet performance so that improvements can be made.
Evergreen Marine has adopted the following actions to reduce CO2 emissions:
- Slow down the speed of the ship
- Continuous monitoring of ship fuel consumption and engine operations to ensure the main engine is working efficiently
- Use the weather navigation to provide the fleet with real-time weather information and routes that optimize fuel efficiency
- Improve cargo handling efficiency to shorten port stays
- Planning of ship cargo loads to maximize economic returns
- Application of special anti-fouling paint to ship hulls
- Replacement of old vessels
Pacific Greenhouse Gases Measurement (PGGM) Project
As part of its goal to retain a leadership role in ensuring a sustainable maritime industry, Evergreen Marine Corp. is part of an ambitious project to measure and monitor the distribution of greenhouse gases in the Pacific Ocean. Nine container ships from Evergreen Line were the first commercial ocean carriers that were equipped to measure marine hydrocarbon and halocarbon emissions as part of an international Pacific Greenhouse Gases Measurement (PGGM) project, which commenced in 2009.
The Evergreen Group is committed to playing its part in the battle to restrict global warming. Striking a balance between providing transport services and being environmentally sensitive is not easy but Evergreen's strong sense of social responsibility will ensure that the company will seriously consider every possible way of minimizing the industry's and its own global footprint. This will also enable its customers to develop greener supply chain systems.
The world's first maritime observation platform for collecting marine boundary data will collect observations of the ocean boundary layer below 100 meters. Evergreen provides ten years of observation assistance to collect atmospheric data as a study of global warming and global climate change. Some of the observation instruments for freighters are manufactured by the Central University in Taiwan and some will be obtained through cooperation with the University of Cambridge in UK. All instruments are expected to be used for more than 10 years.
Global water vapor observations and sea level observations of the Evergreen Marine Freighter will help to understand the concentration changes of greenhouse gases in the Pacific Ocean in the next 10 to 20 years, and establish a three-dimensional spatial distribution of greenhouse gases in the Pacific region. It will be the best gift to the world.
Machinery powered by diesel engines such as container lifters and electric/diesel (E-RTG) gantry cranes are the main source of power in terminal operations. Two additional container lifters were purchased by the Kaohsiung Terminal Div. in July 2017 and May 2018 respectively. The new purchases were intended to improve on the poor emissions and fuel efficiency of old powered machinery, reduce emissions of air pollution and achieve compliance with emission standards. The E-RTG gantry crane reduces diesel consumption by using grid power instead of diesel engines in the operational zone. To maintain the serviceability of the grid power equipment after more than ten years of operation, power rails were upgraded for 7 out of 14 zones by April 2018. The upgrades should result in improved power reliability, lower diesel consumption and reduced emissions. The KC4 automated gantry crane was put into service in February 2017 and its share of overall operations has increased from 12% to 22.7%. Operational movements have also been reduced to take the storage layout into account, resulting in improved operational efficiency, lower energy consumption and reduced emissions.
In 2017, Kaohsiung Terminal Div. invested in the following technological upgrades to save cost and reduce energy consumption:
- Inventory control based on the maintenance plan was introduced to calculate the work load of each machine type, as well as analyze the cost of diesel/electricity consumption, engine maintenance and machinery maintenance to facilitate big data analytics in the future.
- Daily changes in the number and value of parts in inventory are monitored so that they can be controlled.
- Photos and detailed dimensional drawings have been added to materials profiles to provide a clear picture of parts specifications that will be used for the online quotation system.
- Handheld scanners and Wi-Fi wireless transmission hardware have also been set up to speed up materials collection, inventory and annual stock-takes. The equipment ensures that correct data is entered into the system and the accuracy of daily stock-in, materials collection and reporting information.
All Evergreen Marine buildings adhere to our energy conservation policy. To meet energy-saving targets and eliminate energy waste, we not only use high-efficiency energy-saving models for large air conditioning units but also replace all office lighting with LED light-saving fixtures. Active management is practiced for equipment that are energy-intensive or used for extended periods of time. Only refrigerators with first-class energy efficiency are now purchased when refrigerators fail or need to be replaced. More fuel efficient models are also chosen when company vehicles are due for replacement.
