Tremor has a holistic commitment to sustainability. This commitment is embodied in principles of social, financial, and environmental care. The festival holds A Greener Future (AGF) certification, which represents its efforts to minimise its environmental footprint, as well as its role in promoting more sustainable behaviours.

Some of Tremor’s sustainability measures include:

• The dematerialisation of communication (reducing the use of paper and physical materials to a minimum); 

• The minimisation of the production of single-use materials;

• The use of a cashless system that reduces waste related to invoicing (receipts);

• The provision of free water from the public network to festival participants; 

• The offer of a cup to people at the festival, as well as encouraging people to bring their own cups and actively participate in this reuse process;

• The food for our technical and artistic teams is provided by a local entity, minimising food waste and providing strategies for distributing surplus food;

• The provision of a public transport system (Carreira Tremor) for participants and encouraging carsharing;

• The upcycling strategy applied to the festival’s merchandising, as well as the sale of portable ashtrays and water bottles;

• There are waste collection points for undifferentiated and recyclable waste at various locations during the festival.

Tremor presents projects in its artistic and cultural programme that propose new reflections on the archipelago’s natural heritage. As a musical experience in the Atlantic, the festival takes the island of São Miguel as its stage, namely through the development of activities on hiking trails and in nature spaces with a “leave no trace” policy. It proposes participation where there is no consumption of any kind, inviting people to bring their own water and not to smoke, thus avoiding the production of waste and the pollution of spaces. In addition, the organization calls for good use of the spaces and reinforces their maintenance and cleanliness.

Also in its programming, the festival makes a clear commitment to local artistic production and the participation of different communities, through the presentation of artists and bands from the Azores, and the development of various artistic projects focused on different communities. But Tremor also takes place around a table (or multiple tables). The festival proposes actions that encourage the discovery of the traditions and gastronomy of the local community (Cozinha Comunitária, Na Nossa Mesa).

In 2025, the Festival focuses on developing creative and ecologically sustainable solutions that humanise the Portas do Mar Pavilion with areas for rest, enjoyment and conviviality, seeking, through recycling and the use of endogenous materials, to bring the natural world to raw architecture, to reflect on destruction, waste, forgetfulness and entanglement, and to propose reconstruction, regeneration and recreation with reusable, recyclable and sustainable materials.
