Why Is It Material

Climate change is an issue of increasing urgency and importance as it puts pressure on resources such as energy and water that are used across our operations. A low carbon business strategy is not only good for the environment but enables us to better respond to climate change regulations and price volatility of hydrocarbon resources.  

How We Manage

Environmental efforts are coordinated by the Environment Committee. All material business units in Singapore are certified to ISO 14001 Environmental Management Systems. All our global operations abide by relevant environmental regulations and requirements.

What We Do

We have an integrated Environment, Health and Safety (EHS) policy statement, and an Environmental pledge to guide the Group towards environmental best practices.

Our Singapore operations’ greenhouse gas emissions data are independently assured by an external third party.

Energy Efficiency

We play our part in mitigating and adapting to the effects of climate change by implementing initiatives to enable energy efficiency and efficient resource management. We continue to:

  • Acquire equipment that are certified to be energy efficient
  • Install additional solar PV systems on our premises
  • Replace lightings to energy efficient ones
  • Optimise our operations to consume less electricity

Water Management & Conservation

Our businesses use water from municipal sources in their facilities, using it mainly for cooling, cleaning, general sanitation and operational activities, such as aircraft and vehicle washing. In 2016, we set a water usage intensity reduction target of 15% on a business-as-usual basis by 2025 with 2015 as base year for our Singapore operations. We were close to meeting this target in 2019 and will be setting a new target going forward. Meanwhile, we continue to:

  • Install water meters at more locations to enhance tracking
  • Install water-saving devices such as water thimbles and flow reducing valves
  • Promote water conservation awareness through toolbox briefings, talks, and campaigns
  • Perform regular checks to detect leakages in pipes and faucets
  • Optimise further our operations to reduce usage of water

Waste & Effluent Management

We regularly promote 3R (Reduce, Reuse and Recycle) initiatives to help:

  • Reduce scrap materials and consumables usage
  • Reduce paper usage
  • Reuse existing resources such as wooden pallets
  • Recycle waste oil, paper and e-waste

To manage our toxic waste and effluent, we:

  • Optimise processes to reduce toxic waste and effluent
  • Consolidate toxic waste at designated points for collection by licensed toxic waste collectors
  • Ensure that necessary licensing is obtained and effluent discharge criterion are all met before discharge into sewage and waterways
  • Comply fully with Singapore's NEA and other countries' regulatory requirements regarding the safe handling of radioactive material used in non-destructive testing


In 2014, the Group set a target to reduce greenhouse gases intensity by 16% from base year of 2010 for Singapore operations by 2025. This target was raised in 2018 to 36% by 2030, in alignment with Singapore’s Nationally Determined Contribution pledge. This was met in 2019 and moving forward, we will be reviewing our target. Our material Singapore business units are certified to ISO 14064-1 by a reputable third party auditor. To further reduce our emissions intensity, we will continue to:

  • Optimise energy efficiency of workplace processes and replace existing equipment with energy efficient models when due for replacement
  • Prevent contamination of surrounding air using air-pollution control equipment such as scrubbers and spray booth exhausts
  • Ensure stack emission and level of air pollutant are within limits through frequent monitoring by qualified laboratory service providers
  • Reduce Scope 1 emissions by optimising our operational activities such as delivery runs, engine test cells usage and vehicle testing
  • Reduce Scope 2 emissions by installing additional solar PV systems
  • Reduce Scope 3 emissions through encouragement of less air travels and more tele-conferencing
  • Green our facilities and community through annual tree planting activities


Certain parts of our operations generate noise in our community. To be a good neighbour where we operate, we:

  • Inform our neighbourhood in advance of non-recurring works that would generate loud noises
  • Monitor and review noise emission level from our recurring work
  • Keep all noise levels within legal limits and within permitted hours
  • Replace noisy equipment with quieter models and provide sound insulation where applicable
