This is a guest post. The views expressed here are the author’s own and do not represent positions of IEEE Spectrum, The Institute, or IEEE.

A human’s well-being and socioeconomic progress are deeply connected to the environment. People’s livelihoods, businesses, industries, and biodiversity depend on a stable and healthy environment. Sustainability is the foundation of our survival and the future of humanity. Yet decades of environmental degradation have profoundly impacted us, posing significant challenges.

Engineers, researchers, industries, governments, and society must collectively address environmental concerns to protect our planet. Adopting sustainable practices is an essential imperative. It is our collective responsibility to protect and sustain the only planet we have to live on.

World Engineering Day is 4 March. The global initiative celebrates engineering achievements and recognizes engineers’ contributions to progress. This year’s theme, Shaping Our Sustainable Future Through Engineering, underscores the field’s role in advancing sustainability through technological innovation and promoting environmental responsibility.

Engineers help shape a sustainable world, and several of IEEE’s initiatives aim to foster a more sustainable future.

The escalating environmental crisis

The planet is warming. Extreme weather events—including droughts, floods, heat waves, snowstorms, and wildfires—are intensifying, disrupting lives and economies. Recovery costs continue to rise.

Environmental degradation also poses significant health threats. Rising temperatures contribute to respiratory and cardiovascular diseases, the spread of infectious illnesses, and starvation.

Furthermore, air and water pollution, deforestation, and soil degradation are causing significant harm. Air pollution kills about 7 million people annually, with 99 percent of the global population breathing unhealthy air, according to the World Health Organization. It also contributes to cancer, lung disease, and respiratory infections.

Deforestation accelerates climate change by reducing the Earth’s carbon absorption capacity, while soil degradation threatens global food security. One-third of the planet’s land is already severely damaged.

We must take decisive action now to secure a sustainable future: curbing pollution, protecting forests, and restoring our ecosystems.

Although it might feel overwhelming, the right engineering, technology, policy reforms, and behavioral shifts can help create a more resilient and sustainable world.

The role of engineering

Engineering has long been driving world progress, and now it has to be at the forefront of sustainability efforts. Green engineering, also known as sustainable engineering, is an approach to product and application development that balances environmental compatibility with economic viability, profitability, and performance. It contributes to a sustainable environment in several ways:

• Digital transformation. Leverage artificial intelligence, the Internet of Things, big data, and cloud computing to improve business and industrial processes, optimize the supply chain and energy consumption, and reduce carbon footprints.

• Renewable energy innovations. Enrich and expand solar, wind, hydro, and geothermal energy generation and utilization.

• Sustainable infrastructure. Design and build energy-efficient, low-carbon-impact buildings, green smart cities, and intelligent, greener transportation systems.

• Circular economy and waste management. Adopt new technologies and solutions for recycling and converting waste to energy, and develop and use more biodegradable materials.

Despite growing awareness of environmental challenges and early advancements in green technologies, many climate policies and technologies fail to curb greenhouse gas emissions at the necessary pace and scale. One promising solution is technology forcing—a strategy that prompts policymakers and industry leaders to set ambitious environmental targets beyond current technological capabilities, driving innovation and the development of groundbreaking solutions.

Singapore’s push to decarbonize harbor operations, California’s executive order for zero-emission cars, and Germany’s mandate to phase out nuclear power are three examples of technology forcing.

Digital transformation is enabling data-driven sustainability strategies in diverse sectors. Engineers and researchers use IT and AI to optimize resource use and monitor environmental impact. Combined with traditional models, machine learning efforts such as DeepMind can predict weather patterns, help optimize energy grids, and enhance climate modeling. Harnessing blockchain technology’s decentralized systems can help ensure ethical sourcing, carbon-footprint tracking, and green certifications. The IoT can be harnessed for resilient and sustainable agriculture and a more sustainable environment, reducing resource consumption and improving waste management efficiency.

Digital technologies that foster sustainability also indirectly affect the environment, and their impact must be reduced. Technologies such as green IoT, green AI, green cloud, green software, and energy-efficient blockchain are emerging. New AI-specific chips, cooling techniques, and storage drives are reducing data centers’ carbon footprint.

Sustainable software engineering aims to create environmentally friendly software that consumes less energy and fewer resources. It aims to create environmentally friendly software that consumes less energy and fewer resources. The approach also ensures a greener development process, facilitating the creation of reusable, modular software or code.

The Semiconductor Climate Consortium seeks to reduce environmental impact during fabrication and the rest of the semiconductor value chain.

In the energy sector, significant innovations in photovoltaic technology and solar power generation improved efficiency and affordability. Progress in wind energy includes enhanced generation and optimization, floating wind turbines, AI-driven wind farm management, and advanced storage technologies.

Sustainable smart cities minimize their environmental impact while maximizing efficiency by embracing green buildings using nature-based solutions, energy-efficiency measures, smart HVAC systems, and green materials such as carbon-negative concrete. Connected systems powered by IoT sensors, AI-driven traffic management, and smart grids are optimizing urban sustainability.

The shift from a linear economy (take, make, waste) to a circular economy (reduce, reuse, recycle) fosters environmental conservation. Biodegradable packaging materials such as bioplastics, nanocellulose, and algae-based materials, paired with waste-to-energy conversion technologies and advanced recycling systems that use AI-powered sorting and chemical recycling, further enable a more circular economy.

Engineering can address climate change through such measures.

Engineers need to step up

Engineers are uniquely positioned to implement novel solutions that foster sustainable progress and ensure that the infrastructure and systems they build adapt to emerging challenges.

Engineers and developers are problem-solvers, but they also must be futurists. As proactive architects of the future, they should embrace forward-thinking, environmentally conscious practices. To drive impactful change, the engineering community must engage in interdisciplinary collaboration and policy advocacy while promoting ethical considerations. They should dream bigger and turn good ideas into reality.

Let’s pledge—and act now—to create a cleaner, greener planet. If not now, when?

How IEEE can drive sustainability

IEEE advances global sustainability by fostering research and technology development and planetwide collaboration. It has created several initiatives, conferences, and standards to support sustainable development.

• The IEEE Climate Change website provides engineers and technologists with articles, research papers, a list of upcoming events, and other resources.
• The IEEE Standards Association develops technical guidelines that support sustainability in power systems, smart grids, energy efficiency, and environmental protection. IEEE 1547, for example, ensures the integration of renewable energy sources into power grids.
• IEEE’s Sustainable ICT (Information and Communications Technology) Initiative focuses on reducing the environmental impact of information and communication technologies by promoting energy-efficient computing, green data centers, and circular economy practices.
• IEEE Transactions on Sustainable Computing, IEEE Transactions on Green Communications and Networking, IEEE Transactions on Sustainable Energy, and the IEEE Journal of Photovoltaics are just some of the publications that cover the subject.
• The IEEE Xplore climate change collection offers articles on four broad topics: contributions, impacts, alternative energy sources, and prevention and mitigation.
• The annual IEEE SustainTech Leadership Forum provides insights and opportunities to collaborate with stakeholders. This year’s event is scheduled for 19 and 20 August in San Jose, Calif.

Opportunities abound

Sustainability is not just a challenge; it’s also an opportunity. Those who embrace sustainability as a core strategy will thrive. Companies can turn challenges into competitive advantages by adopting greener practices, forging partnerships, and embedding ecological stewardship into their culture.

As Albert Einstein once wisely suggested, our significant problems cannot be solved at the same level of thinking with which we created them.

“Knowing is not enough. We must apply,” said Johann Wolfgang von Goethe, an influential German writer and scientist. “Willing is not enough. We must do.”

We look forward to being a major influence in the journey toward sustainability. It will require innovation, collaboration, and commitment.

Happy World Engineering Day!
