Think green, act green

Green hydrogen as an energy supplier for mobility, heat supply and industrial production is one of the central elements on the way to climate neutrality.

H2EXPO & CONFERENCE, which takes place annually and in even-numbered years parallel to WindEnergy Hamburg - the leading global trade fair for the wind industry - will be the international meeting place for all aspects of the production, distribution and use of green hydrogen. With the aim of driving technological change and sharing scientific knowledge, it offers players from all sectors an excellently networking platform for professional exchange as well as for solutions and ideas that make important contributions to achieving industry-internal and global climate protection goals.

In addition, we are taking a number of measures of our own to ensure that a visit to H2EXPO & CONFERENCE and other events held by our company is an increasingly sustainable experience. In the following, we would like to present some of these sustainability aspects to you.

Carbon neutrality by 2040

WindEnergy Hamburg benefits from the green agenda of the Free and Hanseatic City of Hamburg, which envisages that the city's public companies will become climate-neutral in balance sheet terms by 2040. This politically declared goal thus also applies to the city's subsidiary Hamburg Messe und Congress (HMC), which organises WindEnergy Hamburg.

Sustainability as part of tenders

Taking into account the Green Procurement Guidelines, sustainability is increasingly anchored as an award criterion for HMC. In other words: green light for suppliers who think environmentally friendly.

100% green electricity

Since 2011, HMC has been sourcing 100% of its electricity from renewable energy sources, so H₂ EXPO & CONFERENCE not only presents innovative, green energy concepts, but also acts accordingly itself.

Recycling in booth construction

Exhibitors can book high-quality reusable solutions in our online service booking shop. Step by step, other reusable or recyclable materials will follow alongside existing resource- and environmentally-friendly solutions such as LED lighting, system stands or carpet tiles.

Water protection

Water protection

All year round, we also focus on the sustainable protection of our waters. For example, HMC uses biodegradable cleaning agents at all time and largely dispenses with the use of road salt in winter to clear ice and snow.

Waste separation

Participants at H₂ EXPO & CONFERENCE are encouraged to avoid waste and use resources carefully. Exhibiting companies can collect their waste separately and the waste generated at the event will be professionally and properly separated, recycled or disposed of.


Efficient route planning isn’t only important at sea: our logistics traffic close to the exhibition is controlled and continuously improved by an intelligent slot system. The logistics fleet at the exhibition centre already consists entirely of e-trolleys and HMC's logistics partner naturally demonstrates a sustainability strategy.


Conscious enjoyment is not possible without detailed quality management and processes that take sustainability and environmental protection seriously. Our catering partner Käfer therefore focuses on regional, seasonal and organic food and has an ambitious sustainability strategy.

Arrival and departure

An environmentally friendly exhibition experience also includes the conscious choice of means of transport to and from the fair site. Thanks to the central location of the exhibition halls and their connection to several local and long-distance public transport stations, visitors have many options for getting to and from H₂ EXPO & CONFERENCE in an affordable, comfortable and climate-friendly way. These are supplemented by the wide range of mobility sharing service providers.
