Including the broader digital infrastructure (servers and networks) in a smartphone's life cycle assessment dramatically increases its environmental impact, particularly during the use phase, shifting the dominant impact away from manufacturing. This sustainability research insight is drawn from a 2015 study published in The International Journal of Life Cycle Assessment. Using Literature review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should adopt a holistic approach to sustainability, considering the full life cycle including digital infrastructure, and design for efficient energy use during operation and effective end-of-life recovery.

Key Findings
- 01Manufacturing phase dominates GHG emissions in a 'typical' smartphone's life cycle when only the device itself is considered.
- 02Including servers in the scope increases the use phase impact from 8.5 to 18.0 kg CO2-eq.
- 03Adding the network infrastructure further increases the use phase impact by an additional 24.7 kg CO2-eq.
- 04Current take-back schemes for mobile phones are largely ineffective in reducing environmental impact.
- 05Prompt return of phones could significantly reduce impact through better reuse and material recovery.
Application
Design takeaway
Designers should adopt a holistic approach to sustainability, considering the full life cycle including digital infrastructure, and design for efficient energy use during operation and effective end-of-life recovery.
How to apply
When designing a new electronic device, especially one reliant on cloud services or connectivity, conduct a life cycle assessment that includes the energy consumption of servers and networks. Explore business models that incentivize timely product return for refurbishment or material recycling.
Project actions
- 01When assessing your product's environmental impact, don't just think about the materials and manufacturing. Consider the energy it uses during its 'use' phase and any associated digital infrastructure.
- 02Investigate how your product's design might influence user behaviour and, consequently, its environmental footprint during use.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Highlights the often-overlooked environmental impact of digital infrastructure.
- +Provides a clear quantitative shift in impact assessment when scope is expanded.
Limitations
A simplified LCA in a student project might not have access to precise data for server and network energy consumption, requiring estimations based on available literature or assumptions.
Reliability & validity
Reliability is moderate due to reliance on literature synthesis. Validity is strong in demonstrating the principle of scope expansion, but specific quantitative values depend on the quality of the reviewed literature.
Think critically
How can designers effectively influence the environmental impact of the digital infrastructure that supports their products, given that they often have limited control over server and network energy sources?
Design Principles
"Holistic Life Cycle Assessment: Evaluate a product's environmental impact across all stages, including supporting infrastructure and end-of-life, not just manufacturing."
This challenges the traditional focus on manufacturing as the primary environmental burden of electronics. It highlights the need for designers to consider the entire ecosystem of a product, including its digital components and infrastructure, when evaluating sustainability and making design decisions.
What This Means for Your Design
Making smartphones and using apps uses a lot more energy and creates more pollution than we usually think, because the internet, servers, and phone networks all use a lot of power too. We need to make phones last longer, use less energy when we use them, and make sure they get recycled properly.
How to use in your project
- 1.Use this insight to justify a broader scope for your LCA, including energy consumption of connected services or infrastructure, rather than just the physical product.
- 2.Inform your design decisions by prioritizing energy efficiency during the use phase or designing for easier disassembly and material recovery.

Paragraph starter
This study highlights that a comprehensive life cycle assessment for modern electronic devices, such as smartphones, must extend beyond the physical product to include the environmental impact of supporting digital infrastructure like servers and networks. The research indicates that the use phase, when these digital components are factored in, can significantly outweigh the manufacturing impact, emphasizing the need for design strategies focused on energy efficiency during operation and robust end-of-life recovery systems.
