The Department of Environment, Parks and Recreation (Malay: Jabatan Alam Sekitar, Taman dan Rekreasi; Jawi: جابتن عالم سکيتر، تامن دان ريکرياسي; abbrev: JASTRe), also referred to as the Environment Unit, is a department overseen by the Ministry of Development.

[4] The following park and recreational facilities are under JASTRe:[5] An Act to Consolidate and Modify the Municipal Boards Law.

This Order, which is applicable to Brunei Darussalam's territory, states that everyone has a responsibility to: (a) take, to the extent that it is reasonably practicable, such measures to ensure the protection and management of the environment, and to prevent, reduce, or control any potential hazards that could lead to pollution or damage to the environment; and (b) comply with this Order's requirements.

The formation of the Department of Environment, Parks and Recreation under the Ministry of Development, where the department will also be responsible for issues of landscape and maintenance of recreational areas in the nation, was approved by His Majesty the Sultan and Yang Di Pertuan Brunei Darussalam, according to the Prime Minister's Office.

The parties signed a MoU to advance their mutually beneficial and equal collaboration in the areas of environmental protection and sustainable development.

[17] Over 111 people, including Shell LiveWIRE Brunei alumni, staff from Progresif, and members of the general public, participated in a cleaning effort at Muara Beach on 23 September 2022.

In collaboration with Progresif Sdn Bhd, JASTRE, the Ministry of Development, and the Beach Bunch Association, Shell LiveWIRE Brunei collected more than 241 kg of trash during the third Adopt-A-Beach initiative.

To conserve the environment and keep it free of pollution for the sake of future generations, the motto "It takes a nation to end plastic pollution" emphasizes the cooperation of all stakeholders, including private persons, governmental, private institutions, and organizations.

Several additional events have also been planned, including the expansion of the No Plastic Bag Every Day campaign to convenience stores, restaurants, and food stands.

One of the initiatives is to plan a JASTRe Recycling Day in the districts of Belait, Tutong, and Brunei Muara.
