/Constant improvement


Our conference is at the forefront of the world’s latest developments, discoveries and issues. We also want to demonstrate our commitment to sustainability and that is why we strive to make WeAreDevelopers World Congress a sustainable event. Since sustainability is a significant and a long tradition in Berlin, the city is the best place for events that are both socially and ecologically responsible while also economically successful.

As we all know, many people travel regularly on business or go abroad for specific events in other regions or cities. For Germany, congresses and other events are a major economic factor for the nation and an important source of expert know-how, however, large events are also subject to substantial consumption of resources and cause ecologically harmful emissions – 3.5 kg of residual waste, 5.5 kg of waste paper, 151 liters of water, and 204 kg of CO2 per attendee per day – these alarming figures reflect the environmental impact of conferences.

Due to these concerns, we value improved energy efficiency, waste minimization and environmentally benign modes of travel to and from the venue as the hallmarks of sustainable events. Such actions help avoid mountains of un-recycled goods, prevent unsustainable volumes of traffic, stimulate the regional economy through local sourcing of products and services and follow socially responsible management principles.

We invite you to “go green” and help us support these efforts.


Public transport in Berlin

Mobility & climate protection

  • If possible, use environmentally compatible, public means of transportation to travel (Deutsche Bahn, BVG) to and from the event location and social events – or even go to and from the event by carpooling.
  • If you cannot or do not want to go without your car – or if you need to travel by plane – you can offset your CO2 emissions by means of compensation payments. Donate to climate protection projects supported by atmosfair to offset your CO₂ emissions: Atmosfair and My climate
  • Want to try something new? Velotaxi offers group tours, shuttles and individual chauffeur service with modern, environmentally-friendly bicycle taxis.


  • If possible, choose a sustainable hotel, like Berlin, Berlin (simply use our special conditions).
  • Make use of the environmentally benign offers of your hotel (change of towels and bedlinen only when needed).
  • Turn off all lights, electronic equipment (TV, air condition system, heating, computer etc.) when you leave the hotel room for some time.
Accommodations in Berlin
Berlin CityCube – location of the world's leading developer conference

Event venue

Messe Berlin / CityCube places high priority on protecting nature and conserving natural resources. The company makes every effort to use resources sparingly and practice environmental protection based on the principle that economic thinking and actions can achieve environmental benefits. With this in mind, daily processes are continuously adapted to the latest scientific findings and further developed:

  • As a result of careful energy management and targeted investments, the amount of fuel used for heating and air conditioning was reduced by 23% and CO2 emissions were lowered by 27% from 2005 to 2013.
  • More than 30% of the electrical power required by Messe Berlin is produced by environment-friendly combined heat and power (CHP) systems. Over 40% of the heat energy is produced by burning carbon-neutral wood pellets.
  • Brochures, forms and other documents are made available for download in order to reduce paper usage.
  • Service providers are selected based on their ability to meet the latest environmental protection standards.
  • Materials that are recyclable, biodegradable or reusable are generally used in all work processes.

Procurement, material & waste management

  • We dispense with printed congress documents.
  • If possible, use digital materials instead of paper copies/handouts – simply use our Congress App.
  • Use your own writing utensils.
  • Return your name badges at the information desk after the event.
  • Dispose of your waste (PET, glass, paper, metal, etc.) via the separate collection systems provided at the hotel and at the event venue.
  • In the case of printing, simply use 100% recycled paper – in comparison to virgin paper, approx. 70% less water and 60% less energy is needed to produce recycled paper.
  • Give-Aways – meaningful and sustainable guest gifts!

Catering & gastronomy (not only at the event)

  • Reusability = environmental protection: Give preference to drinks served by the glass, meals served on crockery, milk, and sugar without individual packaging, etc.
  • Seasonal agricultural products from the region: Fruit and vegetables
  • Regional agricultural products: Field crops
  • Regional agricultural products: Meat and fish
