The urgency of climate change and the increasing pressure on businesses to contribute to a net zero future and more specifically to a digital net zero goal cannot be overstated. Every business, regardless of size or industry, has a role to play, and achieving net-zero emissions is no longer optional but essential for long-term sustainability and success. In this blog post, we will explore the concept of digital net-zero and its growing relevance in today’s digital economy.
What is Digital Net Zero?
Net Zero refers to the balance between the amount of greenhouse gases emitted into the atmosphere and the amount removed. It involves reducing emissions as much as possible and offsetting what cannot be eliminated through actions like reforestation or carbon capture technologies.
The globally accepted goal is to reach net-zero emissions by mid-century to limit global warming to 1.5°C above pre-industrial levels. This concept covers notions like the digital carbon footprint and its environmental impact. Let’s dive into it now.
Let’s Focus On The Digital Carbon Footprint
The digital carbon footprint is a key concept in understanding the environmental impact of information and communication technologies (ICT). It represents the total amount of greenhouse gases (GHGs), expressed in CO2 equivalent, emitted directly or indirectly by all aspects of the digital world. This includes the production, use, and end-of-life of electronic devices, as well as the operation of data centres, transmission networks, and end-user terminals like smartphones and computers.
The Environmental Impact Of Digital Is Not Neutral
According to a study by ADEME, the global digital carbon footprint was estimated to be about 4% of global greenhouse gas emissions in 2020, a figure comparable to sectors like aviation.
Data centres, for example, are particularly energy-intensive, consuming nearly 200 terawatt-hours (TWh) of electricity in 2020, which is about 1% of global electricity consumption, according to the International Energy Agency (IEA).
Some more recent studies estimate the electrical consumption of data centres at 560 TWh, nearly 2.5% of global consumption. In France, the 264 data centres would consume 2% of the overall electricity consumption, digital as a whole nearly 10%.
The environmental impact of the digital carbon footprint is also exacerbated by the production and recycling of electronic devices. The manufacturing of these devices requires non-renewable and rare resources and generates electronic waste, of which only a fraction is efficiently recycled. According to the UN, 53.6 million tonnes of electronic waste were generated in 2019.
The digital carbon footprint thus raises important questions about the sustainability of our technological practices. While digital offers considerable benefits in terms of efficiency and connectivity, it is crucial to develop strategies to minimise its environmental impact, notably by optimising energy use in data centres, eco-designing devices, and promoting recycling and the circular economy in the electronics sector.
The environmental impact of this footprint is multifaceted. On one hand, the production of electronic devices is resource-intensive, requiring rare metals and generating electronic waste, of which only 20% are recycled according to an Interpol report. On the other hand, the operation of data centres and networks requires considerable energy, often produced from fossil sources, thus contributing to global warming.
For example, video streaming, very popular, generates by itself nearly 1% of global CO2 emissions, according to a report by the Shift Project, even if the International Energy Agency (IEA) disputes the methodology deployed in this estimate, revising it downwards.
However, it is important to note that digital also offers opportunities to reduce the overall carbon footprint, for example through teleworking, which can reduce travel and thus emissions related to transport.
Moreover, optimising data centres, the increasing use of renewable energies, and the eco-design of devices are levers to reduce the digital carbon footprint. Thus, while the environmental impact of digital is significant, responsible management and use can help mitigate its effects.
The Importance Of The Net Zero Goal And How Digital Can Contribute
The Net Zero Goal, also known as carbon neutrality, is a central concept in the global fight against climate change. It aims to balance the amount of greenhouse gases emitted into the atmosphere with the amount removed.
In other words, to achieve Net Zero, CO2 emissions and other greenhouse gases must be reduced to the maximum, and anything that cannot be eliminated must be compensated by carbon sequestration measures, such as reforestation or the use of carbon capture and storage technologies.
The importance of this goal stems from the urgent need to limit global warming. According to the Intergovernmental Panel on Climate Change (IPCC), it is crucial to limit the increase in global temperature to 1.5 °C above pre-industrial levels to avoid the most devastating effects of climate change. To achieve this, it is necessary to reach the famous Net Zero in greenhouse gas emissions by the middle of the century.
Achieving this ambitious goal requires a profound transformation of economic and social systems. This involves a rapid transition to renewable energies, improving energy efficiency, developing carbon capture technologies, changes in agricultural and forestry practices, and a shift in consumption habits. Governments, businesses, and individuals all have a role to play in this transition.
Achieving Net Zero is not only crucial for environmental protection but also offers economic opportunities, such as job creation in the renewable energy and green technology sectors. However, it also requires close international cooperation, as greenhouse gas emissions know no borders. The success of this goal will depend on collective commitment and action on a global scale.
In this section, we unravel the concept of digital pollution, exploring its definition and the various forms it takes. From the energy-intensive nature of digital devices to the problematic e-waste they leave behind, we shed light on the less visible but significant environmental impacts of our digital age. This exploration sets the foundation for understanding the broader implications of digital pollution.
It is commonly accepted that the environmental impact of the digital sector was concentrated at the crucial stage of manufacturing the equipment as a whole with 78% of greenhouse gas emissions, while the use of this equipment accounted for about 21% according to a study published by ADEME and Arcep in 2022.
While digital technology is essential for businesses today, it significantly contributes to global emissions. The concept of “digital pollution” arises from the energy consumption of data centres, devices, and digital services, as well as the e-waste generated by their disposal. Addressing this issue is crucial for businesses to reduce their environmental impact and contribute to a sustainable future.
How Businesses Can Achieve Digital Net Zero
Optimising Data Centres
Optimising data centres is crucial for reducing the digital carbon footprint, given their high energy consumption and central role in the global digital infrastructure. Data centres consume about 200 terawatt-hours (TWh) of electricity annually, nearly 1% of global electricity consumption, according to the International Energy Agency (IEA). This energy consumption has a direct impact on greenhouse gas emissions, making the energy efficiency of data centres an environmental priority.
- Google
A key strategy for data centre optimisation is the use of renewable energy sources. For example, Google announced in 2020 that it aims to power all its data centres and offices with carbon-free energy by 2030. This initiative, detailed in their environmental report, involves investing in solar and wind energy solutions, thus significantly reducing their carbon footprint. - Facebook
Another important aspect is improving cooling efficiency. Data centres require constant cooling to prevent server overheating, which represents a significant portion of their energy consumption. Facebook, for example, has built a data centre in Luleå, Sweden, that uses cold outside air to cool its facilities, thereby reducing energy consumption for cooling. This information is available in their sustainability report. - Amazon Web Services (AWS)
Optimising server usage is also essential. Using technologies like virtualisation can reduce the number of physical servers needed, thereby increasing energy efficiency. Amazon Web Services uses this technology to improve the efficiency of its data centres, as indicated in their report on innovation and sustainability. - Microsoft
Finally, the design and construction of energy-efficient data centres are fundamental. Microsoft, for example, has experimented with an underwater data centre, Project Natick, which aims to reduce cooling needs by using the natural environment, an initiative detailed on their website.
These examples show that, although data centres are inherently energy-intensive, innovative strategies and careful planning can significantly reduce their carbon footprint, thus contributing to a more sustainable digital infrastructure.
Eco-designing Software and Websites
Developing intelligently designed software is an innovative approach to reducing the digital carbon footprint of businesses. This approach aims to create software that is not only efficient in terms of performance, but also optimised for minimal energy consumption.
Eco-design of software takes into account the environmental impact throughout the software lifecycle, from design to use, maintenance and end of life.
MiNumEco, the interministerial mission for eco-responsible digital technology, has issued interesting recommendations on this subject in its guide to “Good practices for responsible digital technology for organisations”.
A notable example of eco-designed software is that developed by Greenspector, a company specialising in the eco-design of software. Their tool allows you to analyse and reduce the energy consumption of mobile and web applications.
According to their study, using Greenspector can reduce the energy consumption of applications by 50% on average, which translates into a significant reduction in the carbon footprint.
Another interesting initiative is that of Google with its Android operating system. In recent versions, Android has integrated energy saving features such as “Doze Mode”, which limits the background activity of applications when the phone is not in use. This feature helps to reduce the energy consumption of devices, as indicated in their documentation for developers.
Microsoft, for its part, has integrated eco-design practices into the development of its software. For example, Windows 10 offers power management options that allow users to minimise the power consumption of their computer. These options include features such as automatic sleep and power saving settings for hardware components.
Designing websites with sustainability in mind can reduce energy consumption. Strategies include:
- Writing efficient code
- Optimising images and videos
- Minimising data transfer to reduce website loading times and energy use
- Using tools like Ecograder to assess and improve website sustainability
These examples illustrate how the development of eco-designed software can play a crucial role in reducing the digital carbon footprint of businesses. By optimising energy use and integrating sustainable practices from the design phase onwards, software developers can make a significant contribution to the creation of more environmentally friendly technology.
Reducing Reliance on E-waste
Businesses should adopt responsible e-waste management practices, including:
- Repairing and reusing devices
- Choosing sustainable and durable devices
- Partnering with certified e-waste recyclers to ensure responsible disposal
The so-called ecological management of electronic waste is a crucial aspect for companies seeking to reduce their digital carbon footprint. Electronic waste, or e-waste, is one of the fastest-growing waste streams in the world, with an estimated volume of 53.6 million tonnes in 2019, according to a UN report.
Inadequate management of this waste contributes not only to environmental pollution but also to a significant loss of precious resources and an increase in greenhouse gas emissions.
Companies can adopt several strategies for the ecological management of e-waste. One of them is the recycling and refurbishing of electronic equipment.
For example, Apple has developed Daisy, a robot capable of disassembling 200 iPhones per hour, thereby recovering valuable materials for future reuse. This initiative, detailed in their environmental report, reduces the need to extract new resources and limits waste.
Another approach is the adoption of circular economy models. HP Inc., for instance, has implemented a return and recycling program, where used ink cartridges are collected and recycled to create new cartridges. This process, described in their sustainability report, helps to reduce waste and the CO2 emissions associated with the production of new cartridges.
Furthermore, companies like Dell Technologies have launched initiatives to recover e-waste. Their “Dell Reconnect” program, in partnership with Goodwill, allows consumers to drop off their old electronic equipment at Goodwill stores for free, thus promoting the recycling and reuse of electronic components.
However, a word of caution is necessary: it is important to carefully choose the company that will collect and process Waste Electrical and Electronic Equipment (WEEE) due to numerous malpractices observed by Interpol in this sector in Europe.
It can sometimes be tempting to declare old equipment that could be recycled as electronic waste and save the 350 € per ton by following the recycling process.
These examples show that the ecological management of electronic waste is not only essential for reducing the digital carbon footprint of companies but also beneficial for the economy and the environment.
By adopting responsible e-waste management practices, companies can significantly contribute to the reduction of greenhouse gas emissions and the preservation of natural resources.
Embracing Remote Work and Digital Collaboration
Remote work and digital collaboration tools can reduce travel-related emissions. Businesses should adopt flexible work policies and utilise video conferencing and online collaboration platforms to minimise their carbon footprint.
Employee Awareness and Engagement
Employee awareness and engagement are crucial for achieving digital net-zero.
Towards A Responsible Use Of Digital Resources
Limiting the use of bandwidth for non-professional activities, such as video streaming, is an important measure to reduce the digital carbon footprint within businesses.
Video streaming, in particular, is a major consumer of data, and its intensive use can have a significant impact on energy consumption. Indeed, online data transmission requires a substantial amount of energy, mainly used to power data centres, transmission networks, and receiving devices.
In a professional context, reducing the use of bandwidth for non-essential activities such as video streaming can help to lighten the load on the company’s network infrastructure and, by extension, reduce overall energy consumption.
This translates not only into a reduction in operating costs related to energy consumption, but also into a reduction in the company’s carbon footprint.
In addition, by limiting these activities, businesses can ensure a more efficient allocation of bandwidth for critical business tasks, thereby improving productivity and operational efficiency.
Putting this practice into place, companies can adopt bandwidth management policies, raise employee awareness of the environmental impacts of video streaming, and encourage responsible use of digital resources.
Measures such as monitoring bandwidth consumption and implementing restrictions on network use for video streaming during working hours can be effective.
This responsible and conscious approach to the use of digital resources is a step towards a reduced carbon footprint and more sustainable management of information technology.
Regularly cleaning out email boxes is a simple but effective practice for reducing the storage space required on servers, thus helping to reduce the digital carbon footprint of businesses.
Each email stored on servers consumes a small amount of energy, not only for the storage itself but also for the maintenance and security of the data.
The accumulation of many emails, especially those with large attachments, can lead to a significant use of storage space and, consequently, an increase in energy consumption. According to a study by ADEME, an email with a 1 MB attachment stored for a year generates about 19 grams of CO2.
By encouraging employees to regularly clean out their email boxes, companies can reduce the amount of data stored on servers. This includes deleting unnecessary emails, sorting and archiving important messages, and cleaning out spam and trash folders.
In addition, raising employee awareness of the environmental impact of email can encourage them to avoid sending unnecessary messages or to use links instead of large attachments.
This practice, although simple, can have a significant impact when adopted across the company. By reducing the storage space required, companies can not only reduce their carbon footprint but also save money on data storage costs.
In addition, this approach is part of a broader approach to responsible management of digital resources, contributing to a more sustainable and environmentally conscious corporate culture.
A Necessity In Public And Private Organisations
By adopting these behaviours on a daily basis, each employee can play an active role in reducing the carbon footprint of their company, thus contributing to a more sustainable and responsible work environment.
Participating in sustainability training is an essential step for employees who want to actively contribute to reducing the carbon footprint of their company.
These trainings offer an in-depth understanding of environmental issues and sustainable practices that can be implemented in the workplace. By acquiring knowledge on topics such as energy efficiency, waste management, eco-design and renewable energy, employees can not only adopt more environmentally friendly behaviours, but also become ambassadors for sustainability within their organisation.
Similar to the Climate Fresco, there is a Digital Fresco, “a workshop for understanding the environmental challenges of digital technology in a fun and team-based way”. The Bataille de la Tech by Latitudes promotes “committed and responsible tech”.
Sharing this knowledge with colleagues is just as crucial. By spreading the information and best practices learned during training, employees can raise awareness among their peers and encourage a corporate culture focused on sustainability.
This can be done through informal presentations, internal newsletters, workshops, or even sustainability initiatives within the company. For example, an employee trained in waste reduction practices can initiate a recycling program at the office or propose alternatives to disposable products frequently used in the company.
In addition, these exchanges promote innovation and the adoption of new ideas, allowing the company to find creative and effective solutions to reduce its environmental impact.
Knowledge sharing also helps to strengthen employee engagement with the company’s sustainability goals, creating a collaborative work environment motivated by shared values.
In short, participating in sustainability training and sharing this knowledge are key steps to actively involving employees in reducing the carbon footprint of their company. This approach not only promotes a more sustainable work environment, but also reinforces the social and environmental responsibility of the company as a whole.
The 5 Main Challenges and How to Overcome Them
Transitioning to digital net-zero is not without challenges. Potential barriers include upfront costs, lack of awareness, data privacy concerns, and the need for new skills and technologies. Solutions include seeking expert guidance, phased implementation, leveraging government incentives, and fostering a culture of sustainability within the organisation.
Upfront Costs
One of the most significant barriers to transitioning to digital net-zero is the upfront investment required. Many companies, particularly small and medium-sized enterprises (SMEs), cite insufficient budgets as a major obstacle. A survey indicated that 40% of SMEs identified high costs as a primary blocker to achieving net-zero emissions. Investments are needed not only for carbon removal technologies but also for internal research and development aimed at reducing emissions. While these costs can be daunting, they are often necessary for long-term sustainability and can lead to cost savings through improved efficiencies over time. Therefore, companies need financial planning and investment: they can either leverage funding opportunities or run a cost-benefit analysis.
Lack of Awareness
The transition to digital net-zero requires a fundamental shift in organisational culture and awareness regarding sustainability goals. Many companies lack a clear understanding of what net-zero entails and how digital technologies can facilitate this transition.
There is often a disconnect between leadership’s sustainability objectives and the operational realities on the ground. Companies need to foster a culture that prioritises sustainability and digital innovation, encouraging employees to engage with these goals actively.
Comprehensive training programs help educate employees about the importance of digital net-zero goals and how they can contribute. This includes workshops on sustainability practices and the use of digital tools.
Meanwhile, companies must ensure that leadership is actively involved in promoting sustainability initiatives. Leaders should communicate the vision clearly and consistently to foster a culture that prioritises net-zero objectives.
Data Privacy Concerns
As organisations adopt digital solutions to track and manage their carbon footprints, data privacy becomes a pressing concern. The integration of technologies such as IoT sensors and AI necessitates the collection and analysis of vast amounts of data, which can raise issues related to data security and compliance with regulations like GDPR.
Companies must balance the need for data-driven insights with the imperative to protect sensitive information, which can complicate the implementation of digital tools.
Organisations should prioritise robust cybersecurity frameworks to protect sensitive data. This includes employing encryption, regular audits, and compliance with data protection regulations like GDPR.
They should also establish clear data privacy policies and communicate them to all stakeholders. Transparency builds trust among customers and partners, which is essential when collecting data for sustainability purposes.
Need for New Skills and Technologies
The shift towards a digital net-zero framework demands new skills across the workforce. Many employees may not have the necessary training or knowledge to effectively utilise emerging technologies such as AI, machine learning, and blockchain for sustainability purposes.
This skills gap can hinder progress, as organisations may struggle to implement innovative solutions without adequately trained personnel.
To address this challenge, companies must invest in training programs that equip their workforce with the skills needed for effective digital transformation.
They can collaborate with technology experts too and form partnerships with technology providers or consultants who specialise in digital solutions for sustainability. These collaborations can facilitate access to cutting-edge technologies and best practices that enhance operational efficiency.
