Digital Economy Report 2024: Summary

Core Content

The Digital Economy Report 2024 highlights the environmental and social challenges associated with the rapid expansion of the digital economy, emphasizing the need for sustainable and inclusive practices across its entire life cycle. The report is authored by the United Nations Conference on Trade and Development (UNCTAD) and outlines the environmental impacts of digital technologies, from raw material extraction to end-of-life waste management, while also identifying opportunities for leveraging digitalization to promote environmental sustainability.

Main Environmental Impacts

Direct Environmental Impacts

• The ICT sector contributes significantly to global greenhouse gas (GHG) emissions, with an estimated 0.69–1.6 gigatons of CO₂ equivalent emissions in 2020, accounting for 1.5–3.2% of global GHG emissions.
• Production of digital devices and infrastructure has a substantial environmental footprint. For instance, producing a 2 kg computer requires the extraction of 800 kg of raw materials.
• Data centres are a major component of the digital infrastructure and consumed 460 TWh of electricity in 2022, projected to double by 2026. They also consume significant amounts of water and generate greenhouse gas emissions depending on the energy sources used.

Indirect Environmental Impacts

• Digital technologies can have positive indirect effects, such as improving energy efficiency and reducing GHG emissions in sectors like transportation and agriculture.
• However, they may also lead to rebound effects, where increased efficiency results in higher consumption, potentially offsetting environmental benefits.
• Mineral extraction, especially for transition minerals like graphite, lithium, and cobalt, is linked to environmental degradation, social issues, and exploitation of vulnerable communities, including children.

Key Trends and Projections

• Mineral demand for digital technologies is expected to increase by 500% by 2050.
• 5G mobile broadband coverage is projected to rise from 25% in 2021 to 85% in 2028.
• The number of Internet of Things (IoT) devices is expected to grow from 16 billion in 2023 to 39 billion in 2029.
• E-commerce sales in 43 countries rose from $17 trillion in 2016 to $27 trillion in 2022.

Waste and Circular Economy

• E-waste has grown by 30% between 2010 and 2022, reaching 10.5 million tons globally.
• Only 24% of global e-waste is formally collected, with 7.5% in developing countries.
• The report calls for a circular digital economy, emphasizing responsible consumption and production, renewable energy use, and comprehensive e-waste management.
• Developing countries face greater environmental and social burdens due to their role in mineral extraction and e-waste processing, despite limited benefits.

Policy and Governance Recommendations

• The report advocates for a balanced approach to digitalization, combining technological progress with environmental protection.
• International cooperation is essential to ensure equitable distribution of benefits and costs and to support capacity development in developing countries.
• Sustainable procurement and transparent supply chains are recommended to mitigate negative impacts.
• Legal and regulatory measures should be strengthened to address greenwashing and promote circular practices.

Opportunities for Sustainable Development

• Digitalization can drive energy efficiency, resource optimization, and innovative solutions for climate change mitigation and adaptation.
• E-commerce presents opportunities for circular economy and sharing economy practices, such as reducing product returns and minimizing packaging waste.
• Consumer behaviour and corporate responsibility play crucial roles in shaping a more sustainable digital future.

Conclusion

The Digital Economy Report 2024 serves as a call to action, urging all stakeholders to adopt sustainable practices and global governance frameworks to ensure that the digital economy contributes to an environmentally sustainable and inclusive future. It stresses the importance of policy alignment, data transparency, and ethical sourcing to reduce the environmental footprint of digital technologies and support equitable development.
