In this report we refer to the seven commitments made in 2009, which were reviewed and updated in 2011. With a clear focus on the progress and initiatives undertaken during the past year, we have used indicators to measure our performance and identify the challenges that we intend to continue managing in our sustainability model.

At Pacific Rubiales, we believe it is essential to identify challenges and work through them in order to continuously improve, find job and innovation opportunities, and communicate to our stakeholders where the organization is heading. These challenges are relevant to the nature of our business, are measurable, transparent, achievable and flexible.
