Changi Carbon Offsets

Our Approach

At Changi, we take a holistic view towards environmental sustainability, focusing on emissions, waste, water, climate resilience and beyond.

Emissions Reduction
Waste Management
Water Conservation
Climate Resilience

Emissions Reduction

We are committed to working with our partners to reduce emissions both in the air and on the ground. Together, we will transition to cleaner energy for our terminals, as well as vehicles and aircraft operating at Changi Airport.

Water Conservation

We adopt a water optimisation strategy to reduce water consumption and increase water efficiency. At Changi, NEWater – a high-grade recycled water produced from treated used water – forms the majority of our water consumption.

Climate Resilience

We ensure that our critical infrastructure and operations remain resilient against climate change, with special focus on mitigating increasing rainfall intensity, rising sea levels, higher temperatures and increased lightning frequency.

Our targets

-20%

Scope 1 and 2 emissions

We target a 20% reduction in our Scope 1 and 2 emissions by 2030 against a FY18/19 baseline, even as we continue to grow our business.

Level 3

ACI Airport Carbon Accreditation

We continue to maintain our Airport Carbon Accreditation (ACA) Level 3 certification as a commitment to pursuing sustainable growth.

ISO

ISO 14001:2015 Certification

We continue to maintain our ISO 14001:2015 certification across energy and emissions, waste management and water management.

Paving the way to a sustainable future

Through an engineering collaboration with a local university, we reduced our consumption of raw materials by featuring recycled concrete in our aircraft parking bay rehabilitation projects.

Building resilience into our operations

Against the escalating impact of climate change, we are preparing our runways for more intense rainfalls and higher temperatures.

Green Procurement through a lifecycle approach

Enabling sustainable consumption through our Green Procurement policy.
