UmweltDialog.de is the leading German-language information service on corporate sustainability. Partner companies can present their broad commitments to business, social, and environmental topics to an interested public. Launched in January 2003, we count more than 80,000 visitors per month with around 200,000 page views. Our newsletter is sent weekly to ca. 2,800 decision-makers in Germany, Austria, and Switzerland (mainly from media, politics, and economics). In addition, twice a year we publish the UmweltDialog magazine, which reaches 300,000 readers. UmweltDialog is published by macondo publishing GmbH, the first German media company to participate in the UN Global Compact and the Global Reporting Initiative.
