Two decades of sustainability experience_

In 2002 Siren launched the WWF’s first ever briefing to the London Stock Exchange, setting out the need for investment in renewable energy. We were also retained by the World Land Trust to place stories to promote their work protecting key land for biodiversity. Since those early days we have worked consistently to support, promote, and help influence a better approach to living and business.

In the business travel community, Siren has supported the creation of sustainable and responsible travel policies, whilst as representatives for international NGOs in UK and Europe we have worked on natural disasters preparedness and recovery strategies from tropical storms, tsunami’s and flooding. Our work with Caribbean islands and the coast around the Great Barrier Reef embedded conservation into our thinking and working with organic vegetable umami brand Yondu, we have gleaned the inside track on the trending plant-rich world of nutrition. Most recently we have been retained by Delphis Eco, the leader in eco-friendly household cleaning products.
