Could you define what sustainability in IT means, and why it's become a critical focus area for businesses today?
As there’s an unprecedented climate crisis and growing pressure to confront issues of inequality and inequity, companies are faced with expectations from regulators and investors, and from customers and employees, to take meaningful action. While Chief Sustainability Officers and other leaders have spearheaded sustainability efforts in the past, CIO/CTOs are now also essential in meeting those goals.
Data centers consume a significant amount of energy. What innovative approaches can be adopted to enhance energy efficiency in data centers?
The first step for enterprises to reduce their data center carbon footprint is a thorough evaluation of the resources contributing to carbon emissions. Apart from a data center’s location vis-à-vis climate conditions, other factors include the sources of electrical power (e.g., coal, solar), the efficiency of the data center design, and the total IT energy consumption by servers and networks.
To reduce their carbon emissions, enterprises can take measures such as improving the efficiency of their data centers across four pillars:
Infrastructure power
→
Identifying how data center infrastructure can be optimized to consume less power, without hindering necessary business operations. One of the most effective ways to pursue sustainability is through energy efficient infrastructure and optimized power consumption.
Cooling management
→
Cooling is paramount to keep data center equipment functional; hence, higher-efficiency cooling techniques such as liquid cooling and implementing newer technology within the existing one reduce the cooling burden.
IT efficiency
→
Focuses on a data center’s critical load optimization through assessment of server utilization. Gartner’s Phillip Dawson, VP Analyst, says that data center server utilization is often less than 50% and sometimes as low as 20%.
Software efficiency
→
While software is not a direct consumer of energy, it directs and influences the operation of computer hardware, which indirectly impacts the hardware’s energy consumption and hence carbon emissions.
Additionally, another approach is cloud migration. Companies that move from on-site data centers to the cloud report energy savings of 80%. Moving to the cloud, picking a provider that is committed to 24-7 renewable energy and a zero-carbon footprint, and adopting efficient migration approaches can be critical for CIOs to consider in meeting environmental sustainability goals.
Cloud seems to be the answer for many companies. However, don’t the servers where the clouds live consume energy? Can you explain how cloud can be considered “green IT”?
You’re right. E-waste is a huge and growing problem. As the demand for data collection and computation grows, millions of servers will reach end-of-life every year, generating an additional 967 tons of e-waste–and only approximately 20% of that will be recycled. An astounding 84% of companies surveyed by Deloitte believe they lack an effective IT Asset Management strategy for their organization.
Many large companies already have IT asset disposition processes and/or partners in place to ensure company data is properly erased when hardware is decommissioned. Baselining sustainability and e-waste metrics and setting targets to improve is a good first step that many companies can take. Circular business models are also an important way that companies are addressing E-waste. Some major hardware OEMs provide discounts and credits when their customers return old equipment.
What metrics or KPIs does Deloitte recommend organizations use to measure and report on their IT sustainability performance?
What emerging technologies or innovations do you see as game-changers for enhancing sustainability in IT operations?
It’s crucial to acknowledge that the integration of sustainability and climate technologies is not a one-size-fits-all approach. It’s important to focus on what’s critical to the business. That said, there are several critical emerging technologies such as connected IoT and sensors that help gather data on the physical world; AI and generative AI, which are proving to be critical in many areas including cleansing data and improving product and process design; and blockchain and related technologies that are helping with chain of custody for applications like digital carbon passport.
What are the biggest challenges or barriers companies face in achieving IT sustainability, and how can companies overcome them?
Two issues stand out:
Sustainability performance solutions are critical tools to address these challenges because it provides leaders with a clear picture of their roadmap to achieve net-zero targets and gain the insights they need to make informed investment decisions.
