Hello Aspirant,

Environmental engineering is the branch of engineering that focuses on protecting the environment by reducing waste and pollution. The field is also dedicated to improving environmental conditions through remediation. It deals with the design of technologies and processes that control pollution releases and clean up existing contamination. Environmental engineers design, plan, and implement measures to prevent, control, or remediate environmental hazards. They may work on waste treatment, wastewater treatment, site remediation, or pollution control technology.

I hope this helps.
