Arizona State University (ASU) is tackling the complex issue of carbon emissions with a range of strategies aimed at reducing atmospheric carbon and improving human well-being. ASU researchers are collaborating with industry, government, nonprofits, and communities to find solutions that benefit both the planet and society.

Nicholas Rolston, an assistant professor in the School of Electrical, Computer and Energy Engineering, highlights the importance of transforming electricity generation to reduce carbon emissions. He notes that moving away from coal power has already reduced U.S. greenhouse gas emissions significantly. Rolston's lab is working on making solar energy panels more affordable and easier to install.

In transportation, electric cars are part of the solution, but they rely on sustainable electricity sources. Hydrogen fuel and biofuels offer alternative options for reducing emissions from planes and ships.

The U.S. Department of Energy has selected ASU to lead a new Clean Energy Manufacturing Innovation Institute called Electrified Processes for Industry Without Carbon (EPIXC). This initiative aims to use electricity for industrial processes like pasteurizing milk or melting steel while supporting workforce development in underserved communities.

Carbon capture technology is another focus area at ASU. Matthew Green, director of the Center for Negative Carbon Emissions at ASU's Global Futures Laboratory, emphasizes the need for technology that removes CO2 from the air to address historical emissions. The MechanicalTree project on ASU's Tempe campus exemplifies direct air capture technology in action.

Green also explores marine carbon dioxide removal through a project funded by the Office of Naval Research. His team is developing a polymer membrane to filter out salt and CO2 from seawater being processed into fresh water.

Economic considerations play a role in transitioning to green energy systems. Alexander Hill from ASU's W.P. Carey School of Business points out that while there will be costs associated with this transition, it could save money by reducing environmental damages over time.

Environmental justice remains crucial as green energy systems evolve. Danae Hernandez-Cortes works on designing electric transit systems in Maricopa County that meet people's needs while reducing pollution exposure for low-income communities disproportionately affected by pollution.

Clark Miller advocates for integrating decarbonization goals with social and economic impacts when designing clean energy projects. By involving community members in imagining future scenarios, Miller believes better decisions can be made about transitioning energy systems effectively.

ASU continues its efforts towards addressing climate change through innovative research across various disciplines focused on creating harmonious solutions between technological advancements and societal benefits.
