This environmental burden is worsened by the increasing demand for cloud services. It’s also driven by more internet-connected devices and our growing reliance on digital technologies.

Furthermore, the construction and maintenance of data centers deplete natural resources and generate electronic waste. Manufacturing servers, networking equipment, and other hardware components require rare earth metals, which can harm the environment if not managed properly.

Additionally, Jake Madders, co-director of Hyve Managed Hosting, emphasized the complexity of this issue, noting that while climate change is a well-known global concern, the environmental impact of cloud computing and data centers has only recently come to light.

The negative effects of cloud computing on the environment

1. Greenhouse Gas Emissions: Data centers consume vast amounts of electricity, often generated from fossil fuel sources, contributing to releasing greenhouse gases such as carbon dioxide and methane. These emissions exacerbate climate change and its associated consequences, including rising sea levels, extreme weather events, and biodiversity loss.
2. Water Consumption: Cooling systems in data centers require significant amounts of water to dissipate the heat generated by servers and other equipment. This water consumption can strain local water resources, particularly in areas with limited freshwater supplies.
3. Electronic Waste: The rapid pace of technological advancement in the cloud computing industry leads to frequent hardware upgrades and replacements. Improper disposal of obsolete servers, storage devices, and other electronic components can release hazardous substances into the environment, contaminating soil and water sources. Only 12.5% of electronic waste is recycled, leading to a significant amount of hazardous waste in landfills and waterways.
4. Resource Depletion: Manufacturing hardware components for data centers requires extracting finite natural resources, such as rare earth metals and fossil fuels. This depletion of non-renewable resources can have long-lasting environmental consequences and contribute to resource scarcity.

The Global E-waste Monitor 2020 estimates that the world generated a record 53.6 million metric tonnes of electronic waste in 2019, which is expected to grow to 74.7 million metric tonnes by 2030
