is environment engineering part of civil?

Both are different branches in engineering.

You can understand the difference between the two by the given below details

Civil Engineering

The work of civil engineers is everywhere. The roads and bridges we travel on, sure. The buildings we live, work and play in, too. But also systems that bring us clean water and take away waste. Strategies that help us recover from disasters. Energy innovations to power the future. Technologies for green buildings. New materials and sensors for smart infrastructure systems. Projects to alleviate poverty. In other words, civil engineers design the systems, technologies and structures that ready our modern world for a growing, aging human population and make life better in our communities.

Environmental Engineering

If you’ve thought about how we control pollution in the air and water or how we clean up contaminated waste sites or how we assess exposure and human risk, you’re already thinking like an environmental engineer. From clean drinking water and air quality monitoring to pollution controls and sustainable development, environmental engineers are designing new ways to make life better for people around the globe while respecting our world’s natural resources.

Environmental engineers use core engineering skills and a deep understanding of the physical, chemical and biological principles of the local, regional and global environment to help change the world.

Good Luck!!
