As part of our commitment to be transparent about our corporate responsibility initiatives, including our business activities and operations, we report on our performance annually on this website.

This report covers Merck’s corporate responsibility activities and progress as of December 31, 2012, with some additional information relating to 2013.

Where possible, we link readers to further information on and in our annual financial reports.

We have used several external guidelines and measurement frameworks to inform the scope of our reporting. These include the Global Reporting Initiative (GRI) G3.1 Guidelines, the Access to Medicine Index, the Millennium Development Goals, and the 10 principles of the UN Global Compact. This report has been prepared consistent with the GRI’s Sustainability Reporting Guidelines and we are self-declaring to Level A. While this report has not been reviewed externally prior to publication, we are currently having this application level checked by GRI.

Data in this report relate to worldwide operations for the calendar year 2012, except where stated. We plan to publish our next comprehensive corporate responsibility report in 2014.

There have been no significant changes from previous reporting periods in the scope, boundary or measurement methods applied in this report. Acquisitions and divestitures are discussed in the company’s 2012 Merck Form 10–K.

We also have published a brochure of 2012 highlights. Please visit for an interactive version, or visit the downloads & media section of this website to view or print a copy of the brochure.
