The roots of green electronics and sustainable design can be traced back to the environmental movement of the 1970s. During this period, growing concern over pollution, resource depletion, and industrial waste led to the establishment of environmental regulations and agencies worldwide. In the electronics industry, early efforts focused primarily on reducing hazardous substances and improving workplace safety.

Organizations within the electronics sector began forming committees to address environmental challenges. For example, industry groups established environmental health and safety initiatives and conducted seminars to raise awareness about the environmental impacts of electronic manufacturing . These early actions laid the foundation for later sustainability efforts, although the concept of “green electronics” had not yet fully emerged.

At the same time, early examples of sustainable practices appeared in computing infrastructure. For instance, energy recovery systems in data centers—developed as early as the late 1970s—demonstrated that efficiency and environmental considerations could be integrated into technological systems . However, these efforts were often motivated by cost savings rather than environmental consciousness.

Emergence of Sustainable Design Concepts (1980s–1990s)

During the 1980s and 1990s, the concept of sustainable development gained global recognition, particularly following the 1987 Brundtland Report, which defined sustainability as meeting present needs without compromising future generations. This broader understanding influenced design disciplines, giving rise to sustainable design principles.

Sustainable design during this period focused on minimizing environmental impact through energy efficiency, material selection, and waste reduction. The distinction between “green” and “sustainable” design also became clearer. Green design emphasized reducing environmental harm, while sustainability incorporated economic and social dimensions as well .

In the electronics industry, attention turned toward lifecycle thinking—considering the environmental impact of products from raw material extraction to disposal. Researchers and manufacturers began exploring ways to reduce energy consumption in devices and limit the use of toxic materials such as lead, mercury, and brominated flame retardants.

Rise of Green Electronics (1990s–Early 2000s)

The late 1990s and early 2000s marked a turning point with the formal emergence of green electronics as a distinct field. Several factors contributed to this development:

Governments introduced regulations such as the European Union’s Restriction of Hazardous Substances (RoHS) Directive and Waste Electrical and Electronic Equipment (WEEE) Directive, which required manufacturers to reduce hazardous materials and improve recycling.

These developments pushed companies to adopt greener practices, including designing products for easier disassembly, using recyclable materials, and improving energy efficiency.

At the same time, eco-design (or design for environment) became a key approach in product development. Manufacturers began integrating environmental considerations into the design phase, recognizing that most of a product’s environmental impact is determined early in its lifecycle.

Expansion of Design for Sustainability (2000–2010)

From around 2000 onward, sustainable design evolved beyond individual products to encompass systems and services. This period saw the emergence of Design for Sustainability (DfS), which expanded the focus from product-level improvements to broader socio-technical systems.

Researchers identified multiple levels of sustainable design, including product innovation, product-service systems, and systemic societal changes . For example, instead of simply producing more efficient devices, companies began exploring service-based models such as leasing, sharing, and product take-back programs.

In the electronics sector, eco-innovation became increasingly important. Companies experimented with reducing material usage, improving energy efficiency, and designing longer-lasting products. Mobile phone manufacturers, for instance, began incorporating sustainability strategies to address the environmental impact of billions of devices produced annually .

This period also saw the rise of corporate social responsibility (CSR), with companies publicly committing to sustainability goals and reporting their environmental performance.

Green IT and Energy Efficiency (2000s–2010s)
