While the IT sector’s direct contribution to climate change is currently relatively small compared to sectors like transportation and industry, its growing footprint and increasing demand have led to concerns about its future impact. Estimates suggest that the IT sector, which currently contributes between 1.8% and 4% of global greenhouse gas emissions, could account for as much as 14% by 2040. This looming environmental challenge has prompted a global response.
Recognizing this impending challenge, Singapore, a nation heavily reliant on ICT, has launched an ambitious initiative aimed at reducing its ICT-related emissions by 50% by 2030, aligning with global climate goals.
The ICT sector, contributing 5.5% of the GDP, offers both challenges and opportunities. While ICT applications like smart grids and precision agriculture can reduce carbon emissions, the sector’s energy consumption poses a dilemma. This is particularly challenging for the island nation with limited land and renewable energy resources. The nation’s geographic constraints and the global climate crisis necessitate innovative solutions to ensure a sustainable digital future.
Consequently, Singapore’s green technology initiative faces significant hurdles as the country strives to achieve carbon neutrality by 2050. Balancing the need to reduce the carbon footprint of its burgeoning ICT sector with the potential for future economic growth is a must.
To address this delicate balance, Singapore’s initiative is specifically targeting data centres and telecommunication networks as primary sources of greenhouse gas emissions from the island’s ICT sector. Given the substantial energy consumption required for year-round operation and cooling of these infrastructures, Singapore, as Southeast Asia’s leading data centre market with over 60% of the regional market share, aims to significantly reduce its carbon footprint in this sector.
Singapore recognized the need for a comprehensive national strategy to curb emissions and launched its ‘Whole-of-Nation’ initiative. This collaborative approach engaged government leaders, fostered public-private partnerships, and collaborated with civil society organizations under a shared vision of collective responsibility. To achieve this, the Singaporean government has implemented a multifaceted approach that combines regulatory measures, financial incentives, and research and development initiatives.
New regulations mandating carbon footprint disclosure for publicly listed companies have compelled data centres and telecommunications firms to develop comprehensive carbon reduction plans. Singapore’s government has reinforced these efforts through energy performance benchmarks and a green certification program for data centres, as well as stringent energy efficiency requirements for new facilities.
To address the financial barriers that data centres and other organizations face in implementing energy efficiency projects, the Singaporean government established the Energy Efficiency Fund. This fund provides financial support to organizations seeking to adopt energy-efficient technologies, install energy management information systems, conduct energy audits, and optimize resource efficiency in facility design.
In addition to policy-driven efforts, Singapore is investing in technological advancements to reduce the environmental impact of its ICT sector. The Infocomm Media Development Authority (IMDA) has launched a $30 million Green Computing Fund to foster research and development of energy-efficient hardware and software solutions. The fund’s $15 million hardware component is exploring innovative cooling techniques such as immersion cooling and integration with renewable energy sources.
Singapore has allocated approximately USD 7.5 million to fund the second phase of an initiative aimed at enhancing software efficiency. This phase will focus on reducing software footprint, employing more efficient algorithms, and promoting green coding practices. The agency anticipates that this collaborative research and knowledge-sharing with the ICT sector will yield practical solutions that alleviate the growing energy consumption burden associated with data center operations.
