Welcome to the sustainability page of Study Association POLIS! On this page, you can read about what our association
and its members do to be more sustainable. You can also find tips to learn what you can do to be greener!

Why do we focus on sustainability?

Dear visitor of this page,

This year, one of the goals of the board was to create a more sustainable and conscious mindset throughout the association. We share the opinion that it is an important part of the professionalization of an organization nowadays, so we could not be missing out!

We can see a very clear shift during the planning of our events. Our committee members keep surprising us! During these meetings, waste has become a new point of discussion. Do we already have something we can use for this idea? Can we make it ourselves? Do we actually think something adds value to our event?

We are very proud of our members and what they have done so far, and will be achieving! Therefore, we made this page to keep you up to date. Hopefully, you will find here some inspiration as well!


The Board of 2022 - 2023

Meet the Sustainability Officer

Hello everyone!

As you perhaps have already seen or heard, my name is Babette van den Berg and I will be the Sustainability Officer of POLIS this year :)

I feel like almost everyone can feel a certain pressure to become more aware about the environment and be thoughtful about what (not) to do/eat/buy/etc. While we as individuals only have limited influence, there are many little things we can do to make the world a bit greener. As the Sustainability Officer, I will help POLIS and its members with becoming more sustainable. One of my tasks is to brainstorm with committees and come up with concrete ideas on how they can make their events as sustainable as possible. In order to broaden my knowledge and to execute my function to the best of my abilities, I will follow a course from the United Nations about sustainability.
Additionally, I will update this column on the POLIS sustainability page regularly. With this column, I will write about various subjects regarding sustainability. This column will entail sustainability tips and tricks we can incorporate in our everyday lives, like useful apps or instagram pages. In addition, I will write about veggie or vegan seasonal recipes, reviews of books and series/movies or my own experiences with trying to become more sustainable.

I hope you’ll have a look at this page once in a while and maybe even learn something or get inspired yourself!

Lots of love, Babette

November Blog

Hey guys!

For my first ‘real’ blog, I wanted to write a bit about some sustainable practices I have encountered in the last few weeks. Perhaps some of you noticed, but from the 31st of October to the 6th of November it was the National Climate Week in the Netherlands. During this week, special attention was given to what everybody, such as companies, citizens and the government, can do to reduce their CO2 footprint. People could sign up as ‘Klimaat Burgemeester’ (Climate Mayor) or ‘Klimaat Supporter’ (Climate Supporter). As such they got the opportunity to ask questions to and have a conversation with Rob Jetten, the Dutch Minister of Climate and Energy. During the week, several events were held all over the Netherlands with the aim to inform and inspire people to reduce their CO2 footprint and help the environment.
Something particular that stood out to me during this week was a Dutch article written by ‘de Volkskrant’. While most articles praised the Climate Week, the Volkskrant was very critical. They gave some very interesting insights into how Climate Week might not be as progressive or good as we might think of it to be. I will not summarize the whole article, but if you want to read it, you can click on the link below! The main point the author made was that weeks like this turn global crises, i.e. wicked problems, into some sort of ‘temporary’ charity goals. These cannot and do not stress the real urgency of the situation. The National Climate Week will end, but climate change will remain. Should we not care about the climate every week of the year? Maybe some food for thought, and definitely worth a look!
Something else that stood out to me in the last couple of weeks was here in Tilburg at the LocHal. The LocHal currently has two expositions that focus on sustainability, namely the “Stadkas013” and “Expositie Stad = Natuur”. Stadskas013 is a little green oasis on the third floor of the building. It is mostly about what inhabitants of Tilburg can do themselves to create a greener city, house, garden or street. There is information about composting, circularity and food for example. I think it is easy to implement some of these recommendations into your own life. The exposition City = Nature concerns the balance between people and nature, but from an artist and architect perspective. If you happen to be at the LocHal, I would definitely advise you to take a look! The Stadskas013 will be there until the 31st of December and Stad = Natuur will be there until the 20th of November.

Until next time!

Lots of love, Babette

January Blog

Hello everyone!

Firstly, of course, Happy New Year!

The new year often comes with New Year's Resolutions. As the Sustainability Officer, I want everyone to be as sustainable as possible in 2023. However, New Year’s Resolutions can be a little difficult to adapt to. Especially, resolutions regarding sustainability, since these can be expensive and most students are limited in what they can do. Therefore, I did some research and picked two student-friendly tips on how to live more sustainably, which can (hopefully) be easily adapted to your daily schedule.

I think we all know the basic “lower the temperature of your heating system”, “try to eat more plant-based products” and “shower for a shorter amount of time”. While these are of course also very important/useful tips, I don’t think I’ll need to explain these further.

The first tip that I found is to shop more locally and more seasonally. This has many benefits to the environment, to the local community, to your health, and to your wallet. There is not necessarily an exact definition of “local”, but a good starting point could be to buy products that mostly originate from Europe. Shopping locally also often includes shopping seasonally. The benefits of this are that products do not need to be flown over from another continent, or that they do not need many extra chemicals or energy to be produced (like heating in greenhouses). A nice bonus is that local and seasonal products tend to be cheaper.

Tilburg has quite a few markets where you can buy vegetables, cheese, bread, and many other things. I listed them down below. They are definitely worth checking out!

Wednesday: 09:00 - 12:00 Besterdplein

Thursday: 09:00 - 12:00 Westermarkt

13:00 - 17:00 Shoppingmall Heyhoef (ReesHof) 

Friday 09:00 - 12:00 Koningsplein

11:00 - 17:00 Wagnerplein 

Saturday 10:00 - 16:30 Koningsplein

My second tip for 2023 is to start voting in the elections, if you don’t do so already. With your vote, you can influence the decisions of the government that concern the environment. In 2023, Dutch citizens can vote for the Provinciale Staten (provincial states) and the Waterschapsverkiezingen (water boards/water authorities; they take care of water management in the Netherlands). Both the Provinciale Staten and the Waterschappen play an important role in matters such as the energy transition. Provinces are often responsible for setting up windmill parks, solar panel parks and providing subsidies. The provincial states are also the main authorities that execute policies regarding nitrogen, and are thus important for the nitrogen crisis that is currently going on in the Netherlands. The Waterschappen play a role in the energy transition as they own the ground on which windmills can be placed (for example in the sea). The role of the Waterschappen in water management also becomes increasingly important due to the rising sea levels and more extreme weather.

It’s also important to note that every election is important! For now, I just focused on the ones in the Netherlands in 2023, but it’s relevant to all elections in all countries.

These are my tips for 2023, I hope they were helpful!!

Until next time, 


What does POLIS do to stay green?

  • Our summaries went paperless this year! A great addition to saving paper is that online summaries made it possible for us to make them free for all our members.
  • The food that was left after our lustrum weekend was picked up by an organization that could divide the food over the lesser fortunate in the area.
  • The Theme Party Committee was able to reuse all the decorations they bought so far. Reusing decorations is something we try to do within every committee.
  • The Promo Committee didn't print any cantus booklets, but instead showed the lyrics on the TV screens in the Boekanier. This saved 2.400 pages of paper!
  • For their first event, the Food Committee asked all participants to bring containers to bring the leftover food home to enjoy a second time. Secondly, FoodCie went vegetarian this year! The committee has organized two vegetarian meals so far and is busy planning the third. During the week without meat they also did not sit still! More about that on the bottom of the page.
  • The FoodCie wasn't the only committee that went vegetarian this year, during the Business Dinner from the Master Committee Auberge du Bonheur served several vegetarian courses.
  • On the 26th of April, the Community Committee organized the first sustainability event! The event started of with a workshop on how you can make your daily life more sustainable. After that, the committee organized a do-it-yourself tutorial on how to recycle glass bottles to make a self-watering planter out of it. Come see how the flowers are growing at the POLIS room!
  • The Excursion Committee took us to Ghent this year, where the municipality organized a case for us regarding the sustainability of the city.

Easy tips to be more sustainable in your daily life

There are quite a few small changes you can implement on you daily life that can have an impact on your ecological footprint. Another, plus is that with most of these changes you also save money!

Buy your groceries locally! Go to the market for example. In Tilburg, every Saturday there is a market at the Koningsplein and every Thursday at Westermarkt.

Unplug your plugs. Even though, you are not using the cable you are still using the energy. You can save around €100,- per year, so especially for those of you that have to pay your own energy bill, this is interesting.

Shop consciously by buying more second hand clothing, at the thrift store for example. Also, try to buy less online and more at local stores. Another advantage of this is that you preserve the streetscape. If you really want to order something online, send the package to a pickup point instead of your front door.

Green initiatives from our partners

We are not the only ones that value a more sustainable way of living and managing our organization, our partners are also putting their best foot forward!

Coming soon!

Sustainability Event

The second column on this page will tell you more about the sustainability event, organized by the Community Committee, that took place a while back.

The CommuniCie wanted to organize an event where you first learned something and finished with a fun activity. We looked into a few things and we landed on a very interesting workshop by Brandy. Brandy is a very sweet lady that taught us about the different ways to shop with a lower carbon dioxide transmission.

After that, we recycled glass wine bottles by making them into self watering systems for your plants! You can see an example in the pictures. It was fun to do but also a bit scary, because there was a loud pop and the glass could break. No one wanted to wear our pretty safety glasses or oven mitts as protection, luckily everybody still has both eyes!

It was a great afternoon and we are excited for next year's sustainability event!

Week Without Meat 2021/2022

In this column, we will be highlighting the most interesting things our committees have done for sustainability. The kick off is presented by the Food Committee! During the week without meat, 7th till 13th of March 2022, every committee member cooked their favourite vegetarian dish and shared it on FoodCie's own Instagram account (@foodcie22_23). Try them out yourself!
