What is the Best Engineering Degree for Sustainability?
As concerns about climate change, renewable energy, and resource conservation grow, more students are asking an important question: What engineering field is best for sustainability?
The good news is that sustainability isn’t confined to one engineering major. There really is no “best” engineering discipline for sustainability. From designing clean energy systems to building resilient infrastructure, engineering as a whole plays a critical role in shaping a more sustainable future.
Read on to explore several engineering degrees you could get that could directly connect to a career in sustainability. This list is not exhaustive, but will give you a good starting place for discovering how you might be able to impact a more sustainable future through engineering.
Sustainability across engineering disciplines
Sustainability challenges are complex, and they require collaboration across multiple engineering disciplines. Whether it's reducing emissions, improving water systems, or designing energy-efficient buildings, engineering impacts nearly every aspect of sustainability.
For example, engineers could be involved in:
- Energy Transition: developing renewable energy technologies like wind, solar, and hydropower.
- Resource Efficiency: reducing waste and improving recycling systems.
- Climate Resilience: designing infrastructure that withstands climate impacts.
- Sustainable Cities: creating smarter transportation and urban systems.
- Environmental Protection: monitoring and restoring natural ecosystems.
Any solid engineering institution (like Oregon State) should emphasize hands-on learning, interdisciplinary collaboration, and real-world problem-solving (we do). These skills will help prepare students to address global sustainability challenges, and eventually, change the world for the better!
By the way, at the College of Engineering, we have several signature research areas that are focused on building a sustainable future:
- Clean Energy: focused on pursuing several kinds of clean energy technologies, including both renewables and nuclear power.
- Clean Water: focused on developing solutions associated with water availability and quality, aided by expertise in wastewater treatment, water resources management, environmental monitoring, and sustainable infrastructure.
- Resilient Infrastructure: focused on developing solutions that will help the world achieve community resilience in the face of growing natural hazards.
Who knows, you may be even able to do some undergraduate research in these areas while you pursue your degree! That was the case for chemical engineering student, Ishita Joshi. Ishita was involved in research related to turning ocean-acidified seawater into renewable fuel by separating carbon dioxide and hydrogen gases through electrolysis and converting them into hydrocarbon fuel.
Environmental engineering

Environmental engineers focus directly on environmental challenges such as water quality, air pollution, and waste management.
Sustainability career paths in environmental engineering:
- Water resources engineer
- Environmental consultant
- Air quality engineer
- Wastewater treatment designer
Environmental engineering major, Elsie Cordle, opted to major in environmental engineering because it fit her desire to contribute to solutions for water pollution. She was eventually selected to participate in the Clean Water Initiative’s Research Experience for Undergraduates with Stacey Harper, professor of environmental engineering and toxicology, as her mentor.
Electrical and computer engineering (energy systems focus)
Best for: those interested in renewable energy and power systems.
Electrical and computer engineers are essential to building the infrastructure behind renewable energy systems and smart grids. And with Oregon State’s energy systems focus area, you’ll be able to tailor your program by choosing from a range of electives that align with building sustainable energy systems.

Yue Cao, associate professor of electrical and computer engineering, is currently developing an underwater wind turbine that harnesses water currents from marine and river environments to generate power for the grid.
Equipment like this could be incredibly useful for remote communities that need access to clean, renewable, and reliable energy. Hydrokinetic energy remains one of the most underutilized renewable resources, and with a degree in electrical and computer engineering, you could help build similar types of equipment.
Mechanical engineering
Best for: those who want to design sustainable machines and energy systems. Mechanical engineers work on energy efficiency, sustainable manufacturing, and renewable energy technologies.
Sustainability career paths in mechanical engineering:
- Energy systems engineer
- HVAC efficiency engineer
- Product sustainability engineer
Devin J. Roach, assistant professor of mechanical engineering and the Tom and Carmen West Faculty Scholar, is currently developing a rapid-curing 3d printed concrete that results in an 80% percent reduction in carbon emissions compared to conventional cement-based concrete.
Civil engineering
Best for: those interested in sustainable infrastructure and urban development. Civil engineers design roads, bridges, buildings, and water systems with sustainability in mind.
Sustainability career paths in civil engineering:
- Sustainable infrastructure engineer
- Transportation engineer
- Urban planner (engineering-focused roles)
Recently, Oregon State researchers in civil and structural engineering, have been rigorous testing tall mass timber buildings. Mass timber is a more sustainable building product than concrete and steel, and refers to a category of building products in which layers of wood are bonded together to create large panels, beams, and other structural elements.
Chemical engineering
Best for: those interested in materials, energy, and industrial sustainability.
Chemical engineers develop new processes that transform basic matter into all kinds of useful products and materials.
Sustainability career paths in chemical engineering:
- Biofuels engineer
- Sustainable materials engineer
- Process engineer (green manufacturing)
Andrew Tran, who’s pursuing his bachelor’s degree in chemical engineering, is driven by his desire to create a more sustainable future. He works alongside Lucas Ellis, assistant professor of chemical engineering, whose research focuses on materials and catalysis for applications that further environmental sustainability.
Tran’s research involves performing kinetic experiments with a gas phase reactor to investigate plastic upcycling techniques. Unlike traditional plastic recycling – in which certain types of plastic can be melted down and reused a few times, until the material becomes degraded – the Ellis lab’s approach aims to dismantle the long molecular chains that plastics are made of.
The big-picture goal, Tran says, is to create a circular economy for plastics. When a product reaches the end of its useful life, its polymers can be reincarnated indefinitely, rather than being interred in a landfill or drifting out to sea.
