Performance Measurement

In accordance with our "plan, do, assess and adjust" philosophy of our Health Safety and Environment Management System, we regularly update key performance measurements. For more information on how these metrics are tabulated, see Data Assumptions.

Air Emissions

At Phillips 66, we track emissions of sulfur oxides (SOx), nitrous oxides (NOx) and particulate matter (PM) which are produced during the combustion of fuels that contain sulfur compounds.

From 2002 to 2012, emissions from our company-operated assets have decreased 22 percent. Over the same time period, we have invested in many pollution control devices. Among these are12 flare gas recovery systems and eight Fluid Catalytic Cracker (FCC) wet gas scrubbers. Environmental improvement projects were also implemented at our Alliance, Wood River and Borger refineries to reduce flaring and SO2 emissions.

Since 2002, we have reduced SO2 emissions by over 42,000 tons/year, or 83 percent. By installing NOx control hardware and additives on many of our FCCs, heaters and boilers, since 2002 we have reduced NOx emissions by 13,200 tons/year, cutting those emissions in half.

Greenhouse Gas Emissions

The world has a growing need for secure, affordable and diverse supplies of energy. Phillips 66 believes that fossil fuels will comprise a significant portion of the energy mix into the foreseeable future. Managing GHG emissions must be approached from a scientific, economic and societal perspective, balancing long-term sustainability, business vitality and care for the environment. At Phillips 66, we are focusing on sustaining business for the near and long-term by monitoring GHG emissions from our operations, improving our operations by increasing energy efficiency to lower GHG emissions and by conducting fundamental and applied research in alternative energy, carbon capture technology, processing improvements and product innovation. Year-on-year GHG emissions from our operated facilities vary less than 2% during increased utilization rates (see Refining Utilization Rate metric).

Hydrocarbon Spills

Phillips 66 considers any unintentional hydrocarbon release as serious, and we respond to spills as soon as they are discovered. The increase in volume of spills in 2013 was due primarily to two events, into which the company conducted an in-depth analysis to determine cause, adjusted policies and practices, and shared learnings with employees and contractors to avoid them in the future.

Refining Reliability Indicator

Measuring refining reliability is an important metric in evaluating our safety, environmental performance and profitability. Additionally, when we run reliably, we minimize the potential of impact to our neighbors as a result of our operations. We continuously monitor our daily operations and perform proactive maintenance to ensure continued reliability. The utilization rate is an indicator of reliability and has increased annually since 2010.

Through our continuous yearly improvements, we have made substantial progress toward achieving an incident-free workplace; however, we still strive to complete each day without any injuries, illnesses or incidents. Therefore, we recognize that our safety performance must continue to improve, and we understand that this will require full employee and contractor involvement and commitment.

The following chart shows the Total Recordable Rate (TRR) of our combined work force (employees and contractors). The TRR is a measure of the rate of recordable workplace injuries, normalized per 100 workers per year, assuming a 40 hour work week and 50 weeks per year per worker.
