The IT sector must prove it is cutting energy use, not merely promise it. Therefore, the green cloud has moved from talk to measurement: emission reports, PUE, and region choice based on the energy grid

Moreover, a large share of the world’s leading companies already reports its own environmental impact. There are different requirements for each segment, including Information and Communication Technology (ICT). The changes come from regulation, investors, and customers. In addition, the data must be auditable. As a result, this pushes the green cloud onto the IT agenda.

In practice, the Boston Consulting Group sized the problem in a 2021 study. According to that research, the IT sector accounts for between 3% and 4% of total CO2 emissions. In other words, that is twice as much as the aviation sector. Without action, the figure could reach 14% by 2040. Since then, a new factor has appeared. Generative AI workloads have raised data center energy demand.

Furthermore, a study by the consulting firm Allied Market Research looked at the data center segment. It projected growth from US$ 187.3 billion in 2020 to US$ 517.1 billion in 2030. That is estimated annual growth of 10.5%. However, market size is not the central point. The point is the energy spent per workload processed. Above all, that is where the green cloud has to show numbers.

What is the green cloud

It means reducing the sector’s environmental impact with measurable data. Electricity consumption and data center efficiency are the main focus. Therefore, the reference indicator is PUE. It compares total site energy with useful IT energy. Moreover, where the electricity comes from matters as much as how much you consume.

Likewise, on this journey, some paths have already become standard. The first is Infrastructure as a Service (IaaS), which removes data centers from offices. Another is migrations to fully cloud-based services. Reverse logistics for the materials used in IT components also counts. In practice, it only works with an always up-to-date inventory.

As a result, IaaS prevents both overload and idle capacity, since contracting follows real demand. Moreover, rightsizing and shutting down idle resources cut cost and emissions at the same time. In other words, FinOps and sustainability go together.

The green path to the future

Meanwhile, IT companies keep migrating data centers to public clouds. An Accenture estimate pointed to a possible reduction of 59 million tons of CO2. That is the equivalent of taking 22 million vehicles off the streets. However, this gain is not automatic. It depends on the region you choose and on the energy grid that powers it.

In short, it is not just about reducing the amount of equipment in corporate offices. The shift to the green cloud opens other discussions in the ICT sector. Examples include the transition to cleaner energy (solar, wind, and hydro) and less material waste. In addition, reverse logistics must improve — including for data centers — alongside R&D innovations for more efficient data usage.

The path to the green cloud and other environmental strategies seems irreversible for the segment. In an Accenture study with CEOs of large companies, more than 99% agreed on one point. For them, “sustainability is critical to the future success of their businesses”. Here are the figures from that survey:

– 59% said they planned to implement a low-carbon and renewable energy policy;

– 44% stated the goal of zeroing out emissions from their own energy consumption over the following decade;

After all, this is one more proof that IT is involved in high-value actions across different business perspectives.

Factors for the transition to the green cloud

In addition, when choosing partners and suppliers, companies already demand clear criteria. Therefore, ask for evidence rather than promises:

– Provider emission reports broken down by service and region, with an open methodology;

– Contracted renewable energy sources instead of carbon offset quotas alone;

– Commitment to more efficient infrastructure. This includes published PUE, water management, and environmental certification for buildings;

– A carbon calculator wired into the cost dashboard, with auditable data for the ESG report;

What are the advantages of the green cloud?

Therefore, there are concrete benefits in making this transition. Here are some of them:

– Savings on inputs – In recent years, Brazil has lived with sharp swings in energy rates. It is an input every organization needs nowadays. Therefore, optimizing this consumption cuts direct cost.

– Promotion of energy efficiency – Workloads move to data centers with optimized scale and cooling. Moreover, the provider consolidates or shuts down idle capacity automatically. As a result, consumption per transaction falls compared with the traditional environment.

– More cost efficiency – IaaS and SaaS (software as a service) let companies contract only what they need. Moreover, rightsizing removes oversized instances. In practice, several business units share the same infrastructure and the same environmental gain.

From the environment to the business

– Reduction of environmental damage – Every server left running without use is wasted energy. Therefore, shutting down idle environments is both an environmental and a financial gain. In addition, the region you choose changes the result. The larger the renewable share in the local grid, the lower the associated emissions.

– Inspiration for employees – Many people prefer to work at companies aligned with their own values. Sustainability carries more and more weight in that choice. Consequently, this care helps attract and retain technical talent.

– Customer retention – In many contracts, environmental compliance is already a supplier requirement. Therefore, measure, reduce, and publish the data in a sustainability report. As a result, the company answers a due diligence without improvising.

The transition to the green cloud is no longer a trend. It is a contractual requirement. So, what can your business measure today?
