Laguna Lăng Cô cleaning campaign was first launched in April 2016, calling on all staff to keep Laguna Lăng Cô clean and protect the surrounding environment.

In 2017, the location of the program was moved into community areas around Laguna with the aim of improving awareness about protecting the environment with local people.

In 2018, this program was upgraded to the “Green Heart project” with the aim to raise awareness and educate the community about caring for the environment. In this project, children were seen as the key factor in spreading awareness regarding environmental issues to their friends and relatives. Different workshops were conducted each month to help students better understand the environment and possible green initiatives such as garbage classification and recycling. The students were also tasked with taking action to implement their new knowledge to protect the environment.
