Towards a global agenda for digitalization without greenhouse emissions – analysis


Towards a global agenda for digitalization without greenhouse emissions – analysis

Reconciling digitalization with decarbonization is one of the essential elements of the global agenda that has not been appropriately addressed, neither at the G20 nor the COPs levels. Addressing this problem requires national and global measures, both in terms of measuring and raising the awareness among users, citizens, businesses, and public administrations, with regulations that do not strangle the development possibilities of the Global South. - EurasiaReview

This Policy Brief proposes: first, setting up a center to measure and analyze the energy evolution of both ICTs and digitalization. Second, new governance should incorporate environmental regulation responsibilities to the digital sector. Third, acknowledge and respond to the existing gap on global investment in renewable energy and low carbon technology. Fourth, propose the G20’s recognition of the carbon footprint of digitalization. By 2040, non-OECD countries will account for 70% of energy demand; the Global South will be central to this issue and should not be left behind in digitalization.


As Information and Communication Technologies (ICT) become ubiquitous, so does their environmental impact (Martín and Ortega, 2021; Le Monde, 2022). The world needs to get to 2030 with its homework done to reach the goal of net zero by 2050. Digitalization has a lot to do with this, both in terms of facilitating the technologies that will make this possible, and not causing more greenhouse gases through its growing electricity consumption. If we miss the 2030 deadline, we will miss the 2050 one as well. This deadline also applies to the ICT sector in its manufacture, use, and elimination of obsolete devices. With improvements in computational efficiency and the greater sophistication of new peripherals, the manufacturing phase is increasingly crucial in the sector´s environmental impact (Freitag, Ch. et al. t, 2021).

Digitalization, however, entails a hard choice in its adoption. While it is advanced in the industrialized economies, it is much less so in the Global South and constitutes a necessity for this part of the world. Hence, digitalization must be treated as a common good (Ortega, 2021), and this common good must avoid generating more joint damage in environmental terms. This challenge requires global solutions that reconcile digitalization and decarbonization, as new technologies simultaneously help to provide solutions and use more electricity.

Solutions cannot be the same for the Global north and the Global south, and neither are the contexts within the G20. G20 countries play an important role in digitalization and climate change impact, yet they are responsible for around 75% of global greenhouse gases (GHGs), including land-use change and forestry (Climate Transparency Report, 2021). The G20 countries are not homogeneous; their greenhouse contributions, energy sources, mitigation actions, and compromises vary. The Environmental Performance Index from Yale Center for Environmental Law & Policy is an accurate proxy to understand those differences. It is possible to see G20 countries in top positions and others in much lower positions as 165/166.

It is possible to observe a similar situation on the digitalization side. In this case, the Digital Competitiveness Ranking works as a proxy to understand the digitalization status of each country. We can also observe different degrees of penetration of digitalization in each of the G20 countries.

While G20 countries are at the center of the scene, it is projected that 70% of the future energy demand will come from non-OECD countries in 2040 (IEA, 2018). Therefore, developing countries will be central to this issue too. The Global South must not be left behind in digitalization, and it also has to be able to go through a just green and energy transition.

For the Global South, the challenge is multiple. First, improving access to and opportunities for digitalization for all is a pending matter. Second, at the same time, countries in the Global South are facing a green transition, but with less capacity and time. Moreover, patents of critical technologies for a low-carbon economy (Goldthau et al., 2020) are held almost exclusively by OECD countries and China (China Chinese Academy of ICT, 2021). Furthermore, low-carbon global capital allocation primary destinations are Northern America, Europe, and China (Goldthau, A., Eicke, L., Weko, S. 2020). In other words, the Global South must face these changes with a dependency on access to technologies and capital.

Addressing these problems requires national and global actions (Longaretti and Berthoud, 2021), both in terms of measuring and raising the awareness among users/citizens, businesses, and public administrations, with regulations that do not strangle the development possibilities of the Global South.

The 26th UN Climate Change Conference held in Glasgow in November 2021 partially addressed the issue of reconciling digitalization and decarbonization; it set a precedent and the opportunity to be addressed by the G20. One of the first problems to highlight and solve is how to measure these effects. An initial solution is to build a neutral and professional body, such as the Cambridge Centre for Alternative Finance (CCAF), an ongoing project created and maintained by the Digital Assets Programme (DAP) at the Cambridge Centre for Alternative Finance, dedicated to analyzing the Bitcoin network power demand.

Proposals for G20

One of the most significant challenges of our time is reconciling the progress of ICTs and ICT- based applications –known as digitalization– with efforts to achieve a green economy (Langer et al., 2020; Knowles et al. 2022). The first problem is that there is no general agreement on how to consider and build statistics in this respect, nor on whether to include entertainment or the devices, their manufacture, and their disposal as waste when they become obsolete. Furthermore, there is no agreement on the conversion rate of kW/h used by ICTs into tons of CO2 emitted. Estimates of the current and future carbon footprint in different economic sectors and different regions and countries present worrying divergences. It is important to highlight that the G20 in the last years (Argentina and Saudi Arabia Summits) acknowledged the problem of measuring the digital economy and have made substantial contributions[1] to develop common frameworks to try to produce answers to that issue[2]. However, countries have not yet implemented homogeneous measures and there is still a lack of guidelines on environmental dimensions.

The global digital ecosystem is estimated to be responsible for 3% of global primary energy and 7% of electricity consumption. It implies 2% to 4% of greenhouse gas emissions worldwide and the emissions of 15 million to 25 million CO2 equivalents, that is twice as much as emissions from air transport (80% associated with travel)[3]. In 2019, for example, CAPEX (Computers and Devices, Hardware, Servers, Real Estate, Equipment) and supply chain activities accounted for 23 times more carbon emissions than OPEX (Equipment Maintenance, Salaries, Licenses, Administrative Fees, Cloud Services activities on Facebook).

The first step is to properly measure the origins of the electricity used, which is a key factor in this approach (IEA 2018). The problem is significantly mitigated if the energy is clean (i.e. not emitting greenhouse gases, or essentially solar, wind, or even nuclear). It is therefore important to ensure and promote the use of clean energy in ICTs, and in turn, digitalization –especially Artificial Intelligence– can be of great help.

In the meantime, large technology companies are increasingly aware of the need and their own responsibility to reconcile the ecological and digital transitions, not only as a consequence of pressure from public policy, changes in the price of clean energy, and internal developments in the companies themselves, but also in response to public opinion (Hook and Lee 2021).

The growing role of ICTs is not geared towards reducing emissions as underlying efficiency improves. Quite the opposite: their footprint has steadily increased despite becoming much more efficient at transmitting and storing data over the last 50 years. Increased efficiency almost always leads to increased carbon emissions, as efficiency gains are quickly met by the desire to do and use more ICTs. Hence, we see global emissions rising decade after decade, despite continued efficiency gains in all sectors.

ICTs and digitalization are evolving with extraordinary efficiency gains, but this is not preventing their innovation from lowering their impact on global emissions. The new energy-guzzling development is pressing more on the sector’s carbon emissions because blockchain, Machine Learning in Artificial Intelligence, or metaverses, require substantial data centers and high levels of electricity consumption for their operations and cooling (ACM Tech Brief, 2021; Knowles et alt, 2022).

Unless we act and take corrective measures, the emissions will continue growing while we need to reduce them. Economic geography plays an essential role in the ITC systems locations, as shown by the current installations of cloud data centers and cryptocurrency mining. Both relate to using energy, refrigeration, and regulations (Ch Freitag et alt 2021).

This poses a problem in general terms but particularly for the Global South. This evolution is not homogeneous: for instance, only 28% of sub-Saharan Africa’s population has access to the internet (Jackson, 2021) and 200 million people lack access to digital infrastructure in Latin- American (Celis, J. P., & Mendes, M. P. 2021).

Regulation should not strangle its development in its digitalization. Digitalization is needed for all, especially for emerging and developing economies. The impact of regulations and new standards related to the carbon footprint of ICTs and other environmental effects of digitalization need to be measured and understood, considering the asymmetry between the Global South and the Global North. Those changes should contemplate instruments to reduce footprint while reducing the digital divide in the global south to pursue inclusive development.

Digitalization, and especially connectivity as its basis, should be considered and treated as a shared or public good (even if provided by private companies) (Ortega (2021). However, the provision of clean energy is essential for them, and is a source of income for countries lacking hydrocarbons.

From 2017 to 2019, software and hardware optimizations focused primarily on maximizing performance, bypassing the trend of carbon footprint growth. Governments and industries must adress the carbon footprint of ICTs, (Data Centers, digital networks, user devices) and the climatic pros and cons of digitalization in the global economy.

Both assessments are complex and should become a global issue, with global targets and instruments. In many cases, companies are ahead in addressing this challenge as they propose new technologies and applications (big data, machine learning, blockchain, Internet of Things, among others) while only in part incorporating the energy demands they entail.

Complementarity –not conflict– should be generated between the digital and green transitions, while reducing the digital divide requires public, private and public-private policies and collaboration.

Green and digital transitions are inseparable. The ICT footprint in terms of greenhouse emissions must be reduced, yet it is increasing. Thus, the problem should be recognized, measured, and addressed –through better use of ICTs and energy consumption, and in the way devices are manufactured and disposed of– and the digital divide should be tackled with a complementary approach to digital and green transitions.

There is a lack of evidence and policy mechanisms to enforce climate targets across the ICT sector, an issue that was not considered at the G20 Rome Summit, nor at Glasgow COP26.

Public awareness has raised in recent years, with consequences for businesses (which have started to take action) and public administrations (which have started to address it) albeit with approaches still too general. There is knowledge compartmentalization and a lack of connections among the agents responsible for tackling the problems. A change in culture and governance is required. For instance, are proximity data centers, rather than large ones in Northern countries, alternatives to save electricity consumption while contributing to local ICT industries in Southern countries?

The ability of authorities to manage the environmental footprint of digital technology can only be improved by developing tools to measure developments more accurately. Rigorous metrics need to be developed through an environmental barometer to promote best practices across the digital ecosystem nationally and globally.
