Keppel constantly strives to improve our environmental performance throughout our value chain. This includes enhancing the environmental performance of our activities, including eco‑friendly features in our products and services, as well as supporting the global climate change agenda. Business units within the Group are also contributing in different ways to sustainable urbanisation in the cities where we operate.

Renewable energy sources

Keppel invests in renewable energy sources so as to reduce its environmental footprint in the long run.

Sustainable Design

Keppel Land developed a set of Responsible Design Values for all its new projects in Singapore and overseas. The guidelines encapsulate the company's efforts to deliver the best standards in liveability, quality, aesthetics and sustainability.

Green Data Centres

Keppel Data Centres invested US$10 million in data centre startup Nautilus Data Technologies (Nautilus), which employs patented water‑cooling technology in pre‑fabricated facilities which are more cost‑efficient and environmentally sustainable than traditional structures.

Sited on vessels or on land near large water bodies, Nautilus' data centres use the naturally chilled water to cool the facilities, recirculating the water back to its original source with virtually zero water consumption. This eliminates the need for energy‑intensive air‑cooling equipment and water treatment chemicals, and can reduce operating costs by up to 30% while increasing cooling efficiency by up to 80%. It reduces the amount of carbon and pollution emitted by 30%, while using one‑third the spatial footprint with up to five times the server capacity. Through the investment, Keppel will also explore opportunities to tap the Group's experience in the offshore and marine sector for the development of water‑cooled data centres.

Harnessing Renewables

Keppel DC Dublin 1 data centre in Ireland is now fully powered by renewable energy. This initiative by KDCR (Ireland), a wholly‑owned entity of Keppel DC REIT, helps avoid the emission of more than 11,000 tonnes of carbon dioxide per year.

Keppel Offshore & Marine (Keppel O&M) and Keppel Infrastructure are collaborating on a solar leasing project at Keppel O&M's yards, where the renewable energy generated will help offset the yards' energy requirements. In addition, Keppel Corporation's corporate office will be fully powered by clean energy through Renewable Energy Certificates issued and retired with this initiative.

Separately, Keppel O&M entered into a Memorandum of Understanding with Nanyang Technological University to explore collaboration in renewable energy and micro‑grid projects.

Driving Efficiencies

In 2017, the Huawei Cognitive Data Centre reference site was launched as part of a collaboration between Keppel Data Centres and Huawei. Located at Keppel DC Singapore 4, it features technologies geared towards providing a virtualised and energy‑efficient data centre management system.

Keppel continues to implement energy efficiency projects across our operations. Examples of initiatives in 2017 include the replacement of ventilation blowers at Keppel Shipyard with more energy‑efficient ones, as well as the installation of more energy‑efficient LED and induction lights on vessels and machines at our yards.

Water & Waste Management

The Sino‑Singapore Tianjin Eco‑City Water Reclamation Centre was officially opened in June 2017. The Centre, a joint venture between Keppel Infrastructure and Tianjin Eco‑City Investment and Development Co., Ltd., treats wastewater effluent from an existing wastewater treatment plant to produce recycled water that meets China's most stringent standards for urban miscellaneous water consumption.

In our operations, Keppel strives to minimise waste generation, increase opportunities for reusing and recycling, as well as treat and dispose of waste responsibly. Scrap metals are collected at our yards and plants for recycling while used papers are collected and recycled across the Group's businesses. Hazardous waste is handled, stored and disposed in a manner that adheres to best practices and meets local regulatory requirements.

Raising Eco‑Consciousness

Keppel demonstrated its support for climate action by participating in Earth Hour 2017. Non‑essential lights at various shipyards, plants and buildings were turned off for an hour, and activities were organised to raise awareness on climate change.
