IT Sustainability: The Environmental Impact Of Your IT Operations

Posted by | Reviewed by | Last Updated on | Estimated Reading Time: 15 minutes

As of 2023, global carbon emissions from fossil fuels have reached record levels. The world's emissions of carbon dioxide are estimated to exceed 40 billion tons in 2023, with nearly 37 billion tons emanating from fossil fuels. These figures represent an increase of 1.1% compared to 2022 levels and a 1.5% increase compared to pre-pandemic levels. This follows a year-on-year increase in global carbon emissions.

IT Sustainability: The Environmental Impact of Your IT Operations

In 2023, the impact of carbon emissions on the Information Technology (IT) sector was significant and multifaceted. The enterprise technology sector alone was responsible for emitting about 350 to 400 megatons of carbon dioxide equivalent gases (CO2e), accounting for approximately 1% of total global greenhouse gas emissions. This level of emissions is roughly half of what is emitted by the aviation or shipping industries and equivalent to the total carbon emitted by the United Kingdom.

The data centre industry, a critical part of the IT sector, also plays a notable role in environmental impacts. Data centres are estimated to make up approximately 1% of the planet's power consumption. There are concerns about the adequacy of the IT sector's efforts to reduce its climate footprint. Some researchers noted that many of the pledges made by technology giants were not ambitious enough, and industry self-regulation might not suffice to achieve the necessary emissions reductions.

In this blog, we will discuss ways in which your IT department can reduce your CO2 emissions.

Sustainability refers to the practice of meeting our current needs without compromising the ability of future generations to meet their own needs. It encompasses a broad range of issues and practices, often focusing on three main pillars: environmental, social, and economic sustainability. These three pillars are sometimes known as the three Ps: Planet, People, and Profit.

Environmental Sustainability (Planet)

This aspect is concerned with protecting the environment and conserving natural resources. It involves actions like reducing pollution, preserving natural habitats, and mitigating climate change impacts to ensure the health and viability of our planet.

Social Sustainability (People)

This pillar focuses on maintaining and improving societal well-being. It includes ensuring social equity, human rights, labour rights, and community development. The goal is to create a society where individuals can thrive, with access to basic necessities, education, and opportunities for personal and community growth.

Economic Sustainability (Profit)

Economic sustainability involves promoting economic growth and development while ensuring that natural resources are used responsibly and efficiently. It's about creating economic systems that are not only profitable but also equitable and environmentally friendly.

In practice, sustainability involves integrating these three pillars into decision-making processes across all sectors, ensuring that long-term ecological balance is maintained, societies are equitable and inclusive, and economic activities contribute to the well-being of both current and future generations.

Why is Sustainability Important?
