What Is IT Sustainability?

IT sustainability, often referred to as Green IT, is a strategic approach to information technology focused on minimizing the environmental impact of IT operations and their contribution to climate change. It emphasizes designing, manufacturing, using, and disposing of IT equipment, including laptops, desktops, servers, and related systems in ways that are environmentally responsible and resource-efficient. Beyond managing physical hardware, IT sustainability also involves analyzing the broader environmental footprint of IT operations to uncover opportunities for reducing carbon emissions and enhancing energy efficiency throughout the entire technology lifecycle.

Why Is IT Sustainability Important?

As digitalization accelerates, the carbon footprint of IT infrastructure has become a significant concern. The information and communications technology (ICT) sector is responsible for 1.8% to 3.9% of global greenhouse gas emissions, a major contributor to global warming. Data centers are of particular concern, as the global demand for data storage continues to grow. According to the International Energy Agency (IEA), data centers consumed around 460 terawatt-hours (TWh) of electricity in 2022 about 2% of global electricity use and this figure is expected to more than double by 2026.

The rapid advancement of technology and growing demand for IT products and services also lead to increasing electronic waste (e-waste). The United Nations estimates that the world generates about 54 million metric tons of e-waste annually, with only 20% being recycled. Improper disposal of e-waste can release hazardous toxins into the environment, contaminating soil and water sources.

Strategies to Make IT Operations More Sustainable

Organizations can make their IT operations more sustainable by adopting a range of strategies and best practices. Key factors to consider include:

1. Energy Efficiency

A primary method of achieving IT sustainability is by reducing the amount of electricity consumed by data centers, servers, and other IT equipment through improved energy management. For instance, energy-efficient hardware consumes less power and generates less heat, thereby lowering the demand for cooling systems. Additionally, power management software can automate the shutdown of unused equipment, further enhancing energy conservation. The adoption of emerging technologies such as low-power processors, solid-state drives, and energy-efficient cooling systems can also significantly improve operational efficiency. These efforts align with the perspective of Indonesia’s Ministry of Energy and Mineral Resources, which emphasizes that energy efficiency is a crucial step in mitigating climate change. “We have a mandate to reduce emissions by 358 million tons of carbon equivalent by 2030. The first step we can take is energy efficiency, with a target of 37%. Therefore, we must not overlook the importance of energy efficiency,” stated Hendra. Such energy efficiency measures include energy management, improving the efficiency of household appliances, the use of energy-saving public street lighting (PJU), and the adoption of electric vehicles (Kementrian Energi dan Sumber Daya Mineral, 2024).

2. Renewable Energy

A primary method of achieving IT sustainability is by reducing electricity consumption in data centers, servers, and other IT equipment through more efficient energy management. Energy-efficient hardware consumes less power and generates less heat, thereby lowering cooling demands, while power management software can automate the shutdown of unused equipment to further save energy. Technological innovations such as low-power processors, solid-state drives, and efficient cooling systems can also significantly improve operational efficiency. In line with these efforts, Indonesia, through PT Pertamina (Persero), remains committed to reducing its carbon footprint by developing various renewable energy sources, including solar, wind, bioenergy, and geothermal power. Programs such as E-Mas Bayu, which utilizes solar and wind energy in remote areas, and the development of bioenergy products such as Biosolar and Bioethanol, are concrete steps toward reducing dependence on fossil fuels and lowering greenhouse gas emissions. These initiatives demonstrate that the transition to clean energy not only contributes to climate change mitigation but also strengthens national energy security and supports the achievement of sustainable development goals (Pertamina, 2023).

3. Cloud Computing

Migrating IT workloads to the cloud reduces the need for on-premises infrastructure, thereby saving energy and minimizing e-waste. Cloud providers often have access to renewable energy and implement advanced cooling techniques, making their data centers more energy-efficient than traditional on-site facilities. Additionally, the scalability of cloud services means companies can grow without manufacturing and installing new physical servers, reducing emissions from production.

4. Virtualization

Virtualization allows multiple virtual machines to run on a single physical server, reducing the need for additional hardware. Fewer servers mean lower energy consumption and reduced cooling requirements.

5. Sustainable Sourcing

Procuring IT products and services from suppliers that prioritize sustainability helps minimize the environmental impact of the IT supply chain. This often requires considering the broader impact of the supply chain, including:

Extraction of raw materials and natural resources
Manufacturing and transportation processes
Greenhouse gas emissions across Scope 3

6. Product Life Cycle Management

A sustainable IT strategy considers the entire product life cycle, from design and manufacturing to end-of-life management. This approach includes designing products that are durable, reusable, repairable, and recyclable, as well as implementing effective e-waste management programs to ensure proper disposal and recycling of IT equipment, thereby reducing reliance on landfills. In this context, PT Padepokan Tujuh Sembilan, as a software house company, has applied the principles of the product life cycle in its operations. For example, the company continues to use IT equipment that can still be repaired, and when devices are damaged, functional components or spare parts are salvaged and repurposed. This practice not only optimizes resource use but also contributes to reducing electronic waste and supports the company’s sustainability initiatives.

7. Sustainable Software Development

Sustainable software development focuses on efficient coding practices that reduce processing power and memory requirements, ultimately lowering energy consumption. Green coding techniques include optimizing algorithms for efficiency, minimizing code redundancy, and designing software that enters low-power states when idle. Sustainable software is also built to be long-lasting and adaptable to future changes, reducing the need for frequent updates or replacements. PT Padepokan Tujuh Sembilan has implemented these sustainable software development practices by integrating green coding principles into its projects, ensuring that its solutions are both energy-efficient and adaptable, thereby supporting long-term sustainability goals.

8. Emerging Technologies

Artificial intelligence (AI) can optimize processes, predict system failures, and automate routine tasks, thereby reducing energy consumption and waste. Machine learning (ML) algorithms can analyze data patterns to enhance energy efficiency, while Internet of Things (IoT) devices monitor energy usage in real time to ensure optimal performance. For example, smart thermostats in data centers can optimize cooling based on actual demand, significantly reducing energy waste. PT Padepokan Tujuh Sembilan has implemented AI, ML, and IoT technologies across various solutions delivered to its clients. The company develops secure, scalable intelligent systems and integrates IoT and AI based monitoring and energy optimization devices. These efforts help improve operational efficiency, reduce energy consumption in sectors such as banking, insurance, and other industries, and contribute to lowering the overall carbon footprint.

“In this era of rapid technological advancement, the use of IT devices has increased significantly across industries. Today, nearly every professional owns at least two device typically a laptop and a smartphone and many possess three or more. Each device contributes indirectly to carbon emissions through electricity consumption. Although these emissions are not visibly apparent, as they do not produce smoke or direct pollution, they nonetheless represent a substantial share of global emissions. Consequently, IT and sustainability have become inherently interconnected in the digitalization era. Organizations must place greater emphasis on sustainable IT practices, including efficient device utilization, standardized end-of-life management, and fostering employee awareness of the importance of IT sustainability.” Vhydie Gilang Christianto The - Product & Marketing Manager PT Padepokan Tujuh Sembilan
