Hamburger Sport-Verein's HSV Arena will be powered with carbon-neutral green energy provided by Entega, Germany's second-largest green electricity provider.

Entega will also become an HSV exclusive partner. The deal is the latest in a series of CRI and environment-conscious deals for the club, which included making all its travel carbon-neutral since 2008.

"Entega puts an energy partner by our side who is one hundred percent behind our commitment to climate protection and is an ideal match for us," said Katja Kraus, HSV's director of communication and marketing. "The exclusive partnership is an expression of our shared stance on climate protection and a resolute continuation of our taking responsibility for the community, the climate and the environment."

Eike Gyllensvärd, head of international agency Sportfive's HSV team, added: "We've created the ideal starting conditions for a successful cooperation: with their partnership, Entega and the HSV want to draw people's attention to the issue of renewable energy. This shared goal is what makes the exclusive partnership so strong."
