You will lead the charge in operationalizing sustainability by guiding various business clusters through complex regulatory landscapes and ISO 14001 standards.

This role is critical because airports are at the forefront of the aviation industry’s decarbonization challenge.

You will have the unique opportunity to influence infrastructure design and procurement policies that set the standard for the entire region’s transport sector.

Job-FAQs

What are the main missions and responsibilities of this role?

The core of this role involves driving CAG’s environmental strategy by formulating and implementing sustainability solutions across multiple business clusters. You will be the primary lead for ensuring that airport operations align with ISO 14001 standards and evolving environmental regulations. Beyond operational compliance, you are responsible for monitoring and quantifying the outcomes of initiatives related to energy transition, water conservation, and circular economy. This requires a mix of strategic planning and technical oversight to ensure that long-term sustainability objectives are met through tangible, data-backed results.

Key learning opportunities for this job

Working at a premier aviation hub provides unparalleled exposure to large-scale infrastructure sustainability. You will gain deep expertise in how major transport hubs manage climate resilience and carbon emissions at a systemic level, which is a highly sought-after skill set in the current economy. Furthermore, the role offers a front-row seat to policy advocacy and government relations. Navigating the regulatory requirements of the aviation sector while collaborating with state agencies will sharpen your ability to influence high-level environmental standards and corporate governance frameworks.

How does the ideal candidate look like (experience, skills)?

The ideal candidate brings six to nine years of experience, specifically blending environmental policy formulation with technical project management. A strong academic background in Engineering, Economics, or Environmental Science is preferred to handle the rigorous data analysis required for this position. Soft skills are equally vital; CAG looks for someone with exceptional writing and storyboarding abilities. You must be able to take complex sustainability data and turn it into a compelling narrative for senior management and external stakeholders who may not have a technical environmental background.

Advice to stand out and make a successful application

To stand out, focus your application on your ability to bridge the gap between high-level strategy and operational execution. Highlight specific instances where you have successfully navigated ISO standards or environmental compliance frameworks within a complex, multi-stakeholder corporate environment. Demonstrate your analytical proficiency by mentioning specific tools or methodologies you use for data-driven decision-making. Since this role involves significant internal advocacy, providing examples of how you have persuaded senior leadership or government bodies on environmental issues will be a major advantage.

What aspects of the company's sustainability is this role likely to focus on?

The role focuses heavily on decarbonization and the energy transition, which are critical for the aviation industry. You will also oversee circular economy projects and water conservation efforts, ensuring that the airport's resource consumption is as efficient as possible. Additionally, there is a significant emphasis on sustainable procurement and climate resilience. You will be evaluating how future infrastructure developments at Changi can be designed to withstand environmental shifts while minimizing their ecological footprint through every stage of construction and operation.

What are the main challenges someone in this role might face?

One of the primary challenges is balancing operational efficiency with ambitious sustainability targets. In a fast-paced airport environment, implementing new green technologies or waste reduction protocols must be done without disrupting the passenger experience or flight schedules. Another challenge lies in stakeholder alignment. Coordinating diverse business clusters and external partners, each with their own priorities, requires constant negotiation and the ability to demonstrate the business value of environmental initiatives to skeptical parties.

How could a typical day look like for someone in this position?

A typical day might begin with a meeting to review environmental data and progress reports from various airport clusters, ensuring all departments are tracking toward their carbon reduction targets. You might then shift to a planning session with infrastructure teams to discuss sustainability solutions for upcoming airport extensions. Afternoons could be spent drafting policy papers or preparing presentations for senior management. You will likely engage in consultation with government regulators to discuss compliance updates or participate in site visits to verify the implementation of ISO 14001 protocols on the ground.

What are the opportunities for professional growth and development in this role?

Given CAG’s status as a global leader, this role offers significant upward mobility within corporate sustainability or operational management. Success in this position could lead to more senior leadership roles within the Environment and Sustainability department or strategic positions in airport development. There is also the potential for international exposure through CAG’s subsidiary, Changi Airports International. High-performing managers may find opportunities to consult on sustainability frameworks for foreign airports, broadening their impact to a global scale.

The main stakeholders you might be interacting with

You will interact daily with CAG Cluster leads and internal project teams to integrate sustainability into their operations. You will also serve as a key point of contact for senior management, providing the data and insights they need for strategic decision-making. Externally, your network will include government agencies and regulators, such as the Civil Aviation Authority of Singapore (CAAS). You will also collaborate with airport tenants, service providers, and contractors to ensure the entire airport ecosystem adheres to CAG’s environmental standards.
