There's no greenwashing and cafés and restaurants go through a rigorous programme to join - showing supplier invoices and evidence of recycling. Conscious Consumers will help them make any change needed and provides ongoing monitoring.
"It's the integration of the system as a whole, the fact we help businesses connect with suppliers who are certified and genuine, we provide independent support and advice on being a sustainable business, they like that and it's unique.
"Then it ties in with a whole consumer-facing smartphone app marketing platform. It's not about putting a certificate on the wall and making them feel good, it's about providing them with real services around making connections with suppliers and driving demand and driving people into their business," he says.
"It tells stories about the social and environmental practices of a business in a transparent and quantitative way."
That's why the international roll-out must be managed carefully. It's not just an app to sign on to. The underlying certification systems and supplier networks need to be developed, he says.
Barcelona is being used to test what changes need to be made to accommodate other badges, standards, languages, IT systems and so on.
"In Barcelona the issue of workers' wages is key, customers want to be sure cafés are paying people properly," he says.
Conscious Consumers started with voluntary labour but grants from foundations and councils, and a growing base of businesses paying monthly subscriptions, means it can now hire a dozen staff -including five regional coordinators.
"In five years we want to be recognised as a global brand around sustainable business, and it will grow beyond food and beverage into accommodation, fashion, health and beauty products, electronics," Gleisner says.
"Anywhere you buy something and you go beyond 'what's in it for me?' you will use our brand and our technology to find those products and services.
"We want to be a brand people in business look to when they want to improve what they are doing, and so we will drive change.
"It creates demand and an economy that also delivers social and environmental benefits.
"That is the game changer. That is what the people, in the next generation, are looking for. They are not looking to support business that just gives them a good quality product; they want to know about social and environmental performance and we will provide that for them."
