We use renewable energies to generate electricity without polluting the atmosphere with climate-damaging CO2. Here in Rhineland-Palatinate, in addition to solar energy, we also utilise wind power, hydropower, biomass and geothermal energy (heat from the earth) - our top players for clean energy. The more electricity we generate from these sources, the less coal, oil and gas have to be burned. 

Your kick-off 

Put the sun in the lead with your own balcony power plant! Or take out a new contract and buy green electricity from now on. 

Our kick-off 

One of the largest photovoltaic systems in German football stadiums has been installed on the roof of the MEWA ARENA since 2011. We generate 650,000 kWh per year. That's enough to supply around 160 private households with energy for a whole year.

Everyone wants to be mobile in their everyday life and leisure time - but transport is unfortunately the second largest emitter of greenhouse gases. Not every mode of transport is a climate champion. Make the comparison!

How many greenhouse gases does a journey to the stadium cause? Here you are highlighting the real weight of climate-damaging emissions (CO2, methane and nitrous oxide) for one person and a distance of 50 kilometres. The emissions from the generation of electricity or fuel are included. The balance is therefore better if you charge batteries with renewably generated electricity or take other fans with you in the car. It's also more fun! 

By the way: If you travelled this distance by plane, you would have to lift a weight of 12 kg. 

Your kick-off 

Carpool or cycle to the next home game. Or use the shuttle buses or RMV and RNN public transport with your ticket - free of charge! 

Our kick-off

Fans travelling causes a large part of our footprint as a club. Compensating CO2 emissions is a major challenge. We often offer the option of travelling to away games together by bus or special fan trains!

Means of transport and associated emissions in grams (home game, 50 km journey):

Internal combustion car = 9,700 g 

Electric car = 4,500 g 

Long-distance bus = 1,600 g 

Public transport = 3,400 g 

ICE = 1,500 g 

E-bike = 200 g 

Airplane 12,000 g

Everything we eat, wear or buy in general - in other words, our ‘consumption’ - has a major impact on the climate and the environment. 

Raw materials, water and energy are used to produce food and goods. Alle of them have to be transported - often over very long distances. And in the end, a lot of waste is left over, which can pollute the environment. 

Here you can take a closer look at this using the three examples of jerseys, sausages and cigarettes. See what is hidden behind the flaps!

Hero fabric made from plastic bottles 

Sportswear is now often made from recycled polyester. Some of the huge amount of plastic waste becomes raw material for textiles. Are they the right outfit for the top climate league?

Your kick-off 

Swap shirts like the pros! Swapping or shopping second-hand is also a fair play in everyday life and slows down the growth of textile waste mountains. And: even the jersey from the season before is totally sufficient.

Our kick-off 

The jerseys of 1. FSV Mainz 05 are made from 90% recycled polyester - and the fan shop also sells certified clothing made from 100% organic cotton. We also regularly organise workshops at the partner schools of the 05ER Klassenzimmer, where we provide information about sustainable textile procurement.

Less crude oil

No new crude oil needs to be extracted to produce the jerseys, as old bottles or ocean plastic are used. That's actually a good thing.

Microplastics

There is a downside: The smallest fibre particles get into the wastewater during washing. Just one load of jerseys produces almost half a million fibres! Problem: the plastic ultimately ends up in our food and in our organs.

Only your favourite items

So buy new clothes consciously and wear them as long as possible. Because even if your clothes are made from a different material, their manufactureing always consumes raw materials and energy.

What about cotton? 

Not a real alternative. Significantly less water is used in the production of PET fabric. And jerseys made from polyester dry faster.

It's all about the sausage 

In the stadium, every pass counts - and every bite: Discover here what your sausage means for the climate. 

Your kick-off 

Give the substitutes like vegetables a chance from time to time. You can shop in a particularly climate-friendly way if you pay attention to what is in season and is grown nearby. Just try something new. Even chips are vegan! 

Our kick-off 

We also offer meat-free snacks at the stadium - and the trend is rising. For example, vegetarian or vegan hot dogs or sausages and potato wedges with dip.

CO2 footprint

A bratwurst produces around 1.5 kg of CO2 during production and transport, the same amount as a 10 km car journey.

Farting cows 

Cattle and pigs produce methane, a powerful greenhouse gas - every bite of a bratwurst contributes indirectly.

Feed or food? 

Around 70 % of the grain grown worldwide is fed to farm animals instead of directly feeding humans.

Enjoy consciously 

Buy only as much as you need - around a third of the meat produced worldwide is not eaten, but thrown away!

Rubbish world champion

Red card for the little yellow fag. Take a look at it to see how a discarded fag changes the playing field of nature.

Your kick-off

It is of course best for the environment and your health to quit smoking or, even better, to never even start. If you're a smoker: never simply throw the butts away, but dispose of them in the residual waste. Let others know as well. 

Our kick-off

There are plenty of bins for residual waste everywhere here. We also regularly organise waste collection campaigns after home matches. Why don't you join in next time and help us keep our stadium clean?

Mountain of rubbish

Around 4.5 trillion cigarette butts are thrown away worldwide every year - this is the most common form of rubbish on the planet.

Toxic cocktail 

Over 7,000 chemicals gather in the filter, including nicotine, arsenic and lead - many of which are toxic for the environment.

Water pollution

A single cigarette butt can poison up to 40 litres of clean water.

Microplastics 

Cigarette filters break down into microplastics, which end up in the food chain and therefore also in human or animal's bodies.
