The government also proposes to require 10% of the capacity of data centres installed in Brazil to be offered to local companies, which would mean promoting the migration of these companies to the clouds of foreign giants. In other words, the policy itself reinforces technological subordination by encouraging the expansion of the current digital ecosystem, already dependent on these technological giants.
Socio-environmental extractivism
Data centres also have a major socio-environmental impact, caused, among other factors, by their enormous consumption of energy and water.
One need only look at the environmental damage and the worsening living conditions of people who live near data centres in Ireland. The European nation established itself very early on as a magnet for these investments, and its population is now suffering the effects of a collapsed energy matrix, reportedly including higher energy prices as the centres increase consumption and demand.
This could happen, for example, in Caucaia, a municipality in the Fortaleza region of north-eastern Brazil, where the company that operates TikTok plans to build a data centre. The Intercept, a nonprofit news organisation, estimates this centre will have a daily energy consumption equal to that of2.2 million Brazilians.
This is a global problem. According to the United Nations Conference on Trade and Development, between 2018 and 2022, the 13 largest data centre operators' electricity consumption increased by 1.5 times, from 50 to 125 terawatt hours. Almost two-thirds of that consumption is accounted for by Amazon, Google and Microsoft, in that order.
Although they power their data centres with renewable sources – partially, because they keep fossil fuel reserves as a backup in case of supply interruptions –, these companies' business is based on encouraging consumers to use more and more services in their cloud. That renewable energy could instead be put to more important uses, such as public transport systems.
In terms of water consumption, in 2022, Microsoft's consumption grew by 34% and Google's by 22%. Google states in its environmental reports that it is increasing its water replenishment (from 6% in 2022 to 18% in 2023). But even discounting this replenishment, its net water consumption grew by 205% between 2016 and 2023.
In response to these concerns, the Brazilian government promised its policy would include environmental regulations. However, the promise is in doubt as the Ministry of the Environment is not being part of policy discussions.
The example of Chile
When it comes to environmental rules, we need to look at another South American country: Chile.
In December 2024, the Chilean Ministry of Science launched the National Data Centre Plan, with two somewhat contradictory goals: to promote economic growth and to regulate the industry, which has been setting up without control in the country's metropolitan region.
The main instrument of this plan was a territorial viewer, a digital tool designed to map almost 80 socio-environmental indicators and regulations for each square kilometre of the territory of Antofagasta, a region in the far north where plenty of energy is available, with plans to expand the mapping to a national scale.
This tool, which is now ready for implementation, makes it possible to identify areas where the socio-environmental impact of data centres would be lower. This viewer, which was designed entirely by the Chilean public administration, is an example of government capacity building and planning that would allow for more effective regulation.
However, as in Brazil, corporate pressures appear to have prevailed, calling into question whether this tool will be used effectively.
