Lais AddedSunday, December 10, 2017 at 12:18 AM I am currently majoring in mechanical but also interested in environmental engineering. I want to work in reducing emissions from airplanes, is possible for me to do that with just mechanical degree? I am having a hard time deciding which major I want because I enjoy topics/research ideas on how to reduce the amount of air pollution, and to work on methods to protect the environment. I like the idea of working on different projects to protect the environment such as reduce the amount of energy we use and protect wildlife. I am just afraid that if I major in environmental engineering, I won't be able to do research related to airplanes. Like for example, work on a new alternative fuel to reduce emission or work on better design of the airplane to reduce the amount of fuel it uses. I am trying to find the best fit for myself between mechanical and environmental.

I think your current major in mechanical engineering will position you very well to work on emission control and aircraft design to further your goal of increasing energy efficiency and protecting the environment. The environmental engineering programs that I am familiar with have more of a focus on civil and chemical engineering principles, while your mechanical engineering program of study should prepare you to apply mechanical and thermodynamic principles in many ways, including energy efficiency and emissions reduction. Best of luck in your future career! Regards, Peggy
