Eco Consciousness

At Redbridge International School, we are committed to fostering an eco-conscious community and instilling a sense of responsibility towards our environment.

Through our concerted efforts and initiatives, we strive to make a positive impact on the planet while nurturing future generations to become stewards of sustainability.

In 2022, Redbridge International school entered the Eco-School accreditation process. During the  2023/24 academic year, we conducted a thorough diagnosis of our school’s environmental practices and identified areas for improvement. Through collaborative efforts involving students, faculty, and staff, we formulated a comprehensive action plan with specific objectives aimed at achieving the prestigious Green Eco-School Flag.

We are proud to share our efforts and achievements in fostering a sustainable and Eco-friendly environment.

This year, we have embarked on various initiatives that reflect our commitment to sustainability, paving the way for us to win the prestigious Eco-Schools flag.

Here are some of the exciting projects we’ve been involved in:


Central to our eco-conscious aspirations is the active involvement of our students.

We firmly believe in empowering our future leaders to champion sustainability initiatives within our school community. To this end, we have elected eco-delegates from Year 4 up to 3ème (9th grade), who play a pivotal role in advocating for eco-friendly practices and spreading awareness about the importance of being an eco school.

These dedicated eco-delegates serve as ambassadors of sustainability, inspiring their peers to embrace environmentally responsible behavioUrs and actively participate in the various eco-friendly activities and initiatives implemented at Redbridge International School.

Through our ongoing commitment to sustainability education, collaborative action, and student leadership, we are proud to foster a culture of environmental consciousness at Redbridge International School. Together, we are making a difference today for a greener and more sustainable tomorrow.


Bird Watching during Forest School outing with Year 4 (4º Ano / CM1 students) in partnership with Sociedade Portuguesa Para o Estudo das Aves.

During a Forest School outing on 2 May 2024, the Portuguese Society for the Study of Birds (SPEA) organized a birdwatching session in Monsanto. The event, “Portuguese Birds and Their Habitats,” introduced students to local birds, their characteristics, and the trees they inhabit.

Guided by biologist Carolina B. from SPEA, students identified birds and their habitats using provided binoculars. They then drew and illustrated the birds and trees they observed. SPEA also provided magnifying glasses for detailed exploration.

Forest School teacher Sabine P. used a short story and theatre to discuss migratory birds and how climate change affects their habitats and cycles, using the presence of swallows in the area as an example.


Our Year 8 students took a culinary journey to create an Eco Mediterranean Menu.

They proposed dishes using sustainable ingredients, carefully considering seasonal availability and dietary restrictions. After a school-wide vote, the winning menu was introduced in our canteen. This initiative not only promoted healthy eating but also educated our students on the importance of sustainable food practices. The new menu has been a hit among students and staff alike, bringing a fresh and eco-friendly twist to our daily meals.


Though we didn’t start with a full vegetable garden, our small aromatic garden project blossomed into a successful venture.

Under the guidance of Angela, our project leader, and Karen, our kitchen’s head chef, students from Early Years to Secondary School actively participated in planting and maintaining various aromatic herbs and vegetables.

This hands-on experience has sparked a keen interest in gardening among our students and has provided fresh produce for our kitchen. The project continues to grow, showing great promise for a more extensive vegetable garden in the future.


Our Noise Brigade undertook the task of measuring noise levels within the school, particularly in the canteen.

The findings revealed that the noise level was comparable to the bustling sounds of a busy street. This project highlighted the importance of noise pollution awareness and paved the way for implementing strategies to create a quieter,
more conducive learning environment.

Healthy Food Policy

Our school enforces a food policy with no nuts, fried foods, pork, or processed foods. Sugar and salt are restricted, and gluten-free, lactose-free, vegetarian, and vegan options are always available at lunch and snack times. There are no bar services or vending machines, and the espresso machine is for teachers and staff only.

Canteen Brigade Efforts

The Canteen Brigade analyzed food waste by weighing organic waste at the end of each menu cycle. They identified meal types and nutritional profiles and found that pasta and meat dishes are the most consumed, while vegetarian options are the least.

To minimize food waste, we presented food waste data at a Primary School Assembly. After the Easter holidays, the presence of a monitor near the bin encouraged students to finish their meals.

We also raised awareness of proper portion sizes, with canteen staff asking students how much food they want.


The Early Years participated in the Edding Challenge by creating a poster to highlight the importance of recycling felt tip pens and showing the location of the Edding Return Box.

The poster features pens as superheroes with capes,
flying towards the Return Box, under the message “Vamos ajudar o Planeta” (Let’s help the Planet) and the slogan “Façam as canetas voar. Vamos todos reciclar” (Make the pens fly, Let’s all recycle).

Children brainstormed ideas, with one suggesting the superhero theme and another adding capes. They took photos of the Return Box location and decorated the poster with stamps and capes.

Initially, the Return Box was at the school reception, but younger students had difficulty reaching it due to the school’s layout. To solve this, we created multiple return points using recycled chickpea tins from the kitchen.

Each tin was labeled with a photo of the Return Box and the Early Years poster. These tins rotated between classrooms daily, and when full, students would bring the pens to the main Return Box at reception.

So far xx have been returned.

Notebooks for EYfrom Year 3 students

As part of our ongoing commitment to being an eco-school, our amazing Year 3 students embarked on a creative and sustainable project! They gathered scrap paper from classrooms throughout the primary years building and
transformed them into beautiful, handmade booklets.

These booklets were then shared with the Early Years students, creating a heartwarming moment of connection and joy. Seeing the smiles on everyone’s faces was truly magical!

This project not only promoted recycling and creativity but also fostered a sense of community and generosity among our students. We are so proud of their efforts and the positive impact they’re making on our school environment.

Planta Tree

On a chilly winter day, our Year 3 students ventured into the heart of the Parque Natural de Sintra-Cascais for a forest school day.

They planted trees to support local biodiversity and native forestation. This hands-on experience
taught our students the importance of preserving natural habitats and contributed to the conservation of our beautiful local environment.

Ecological architecturalchoices

For our Campus at Campo do Ourique, we have opted for an ecological construction in solid wood, favouring the use of bio-sourced materials from renewable resources (cross laminated timber – CLT). Solid wood is the only structural material that stores carbon instead of emitting it. And transforming wood into CLT and transporting it requires less energy and therefore low CO₂ emissions, giving timber construction an exemplary carbon footprint.

Beyond the ecological process, in terms of comfort of use, solid wood offers superior insulation, soundproofing and fire resistance compared with traditional construction.

Based on a French invention developed by engineer Pierre Gauthier in 1947 and first used by French architect Jean Prouvé, redeveloped by Swiss and Austrian industry since the early 1990s, this high-precision construction system is now known as CLT (Cross Laminated Timber);

Made from a renewable resource that is 99% natural in origin and fully recyclable, CLT is the only structural
material that stores carbon instead of emitting it;

Solid wood offers new aesthetic, sensory and functional possibilities: the warmth of visible wood, insulation and soundproofing of rooms, and fire resistance.

One of the advantages of CLT is that it can be totally prefabricated in the factory; BIM (building information
modelling) applied to CLT makes it possible to combine impeccable site preparation with a diversity of architectural forms. BIM and timber construction are a guarantee of speed and quality of execution.
