Sustainability is becoming increasingly important for all businesses. This also includes the events sector. After all, an event or congress often has an enormous impact on the environment: visitors need to travel long distances to get to the location, they consume an enormous amount of energy and water in a short period of time, and they produce gigantic amounts of waste. In order to reduce the impact of an event or congress, it’s vital to organise them as green and sustainable as possible. Naturally, this responsibility lies with the organisation.
