Natural gas, on an energy equivalent basis, emits 45 percent less CO2 than coal and 27 percent less CO2 than oil, making it the best fossil fuel source available to reduce greenhouse gas emissions.

America’s natural gas customers are leading the way on carbon reductions and energy efficiency. In fact, despite a 70 percent increase in the number of homes using natural gas, greenhouse gas emissions in total are flat and have decreased 40 percent per household since 1970.

Because of its efficiency and environmental benefits, the use of natural gas to generate electricity has increased dramatically during the past 11 years – of the more than 240 gigawatts of net summer electric generation capacity added since 1999, more than 87 percent has been fueled with natural gas.

Natural gas is a vital ingredient for production of many alternative and renewable energy sources. It is used to manufacture lightweight steel for fuel-efficient cars and trucks, to produce hydrogen for fuel cells, as a component of windmill blades for wind energy and to grow the corn needed for ethanol. Natural gas is also a backup fuel source for intermittent solar and wind energy.

Natural gas is primarily a domestic energy source. In 2010, 88 percent of the natural gas consumed in the United States was produced in the U.S. The remaining natural gas supply came from Canada (10.5 percent), with 1.5 percent imported as liquefied natural gas (LNG).

The domestic natural gas resource base is large, estimated to be 2,074 trillion cubic feet, enough to meet current U.S. consumption for another 100 years.

According to the National Transportation Safety Board, pipelines are the safest form of energy transportation -- safer than transportation by truck or rail.

dirECT uSE OF NaTural GaS The direct use of natural gas for homes, businesses, industries and vehicles is the most efficient use of this valuable natural resource and an important part of the solution to our nation’s growing energy issues. The expanded use of domestic natural gas can help revitalize our economy, reduce greenhouse gas emissions and enhance our national energy security.

Unlocking the potential for direct use in our markets is vital to shareholder value and to our sustainability strategy. We are working to advocate policy solutions for expanded natural gas usage. We are also providing customers tools to assess how natural gas can be used in their homes and businesses as a way to help them reach their own emissions reduction and efficiency goals.

In addition, the use of natural gas for power generation, especially when it replaces high-emitting coal resources, can be a key strategy in reducing emissions. According to the Gas Technology Institute (GTI), an increase of natural gas use in electricity production, as well as transportation, residential, commercial and industrial applications, can be a major component in reaching a 42 percent reduction in carbon emissions by 2030.

we will always think safety first

Piedmont Natural Gas puts safety first for our customers, our communities and our employees. This begins with employees who fully understand the policies and procedures that have given Piedmont Natural Gas one of the best safety records in the business.

EmPlOyEE SaFETy PrOGramSPiedmont has established company-wide safety goals with incentives designed to encourage employees to be always mindful and proactive about on-the-job safety. Our target goal for 2011 is to have 80 percent of our employees participate in at least four meaningful safety-related activities.

Each time an employee participates in a safety-related activity, he or she receives points in our Rewards & Recognition system. Once specific amounts are accumulated, employees can “cash in” their rewards points for a variety of items ranging from books to clothing to electronics. In addition, below are various safety programs offered at Piedmont.

Annual Safety SummitLeaders of Piedmont’s Safety Department hold an annual Safety Summit for representatives from across the company to report progress on safety initiatives, share experiences and learn about new safety issues, techniques and programs.

Take 20In 2010, Piedmont’s Safety Committee introduced a new communications program to encourage employees to be more mindful of the little things that can prevent accidents – on and off the job. The program is called Take 20, and the message is simple – take 20 seconds to think before you take a specific action. Take 20 messages are sent on a regular basis and cover topics ranging from safe vehicle operation to staying safe around the house.

OSHA’s Volunteer Protection Program (VPP)Piedmont is the first natural gas local distribution company (LDC) in the country to fully adopt this program, which surpasses standard OSHA regulations. The VPP recognizes employers and employees who have implemented effective safety and health management systems and maintain injury and illness rates below national averages for their industry. In VPP, management, labor and OSHA work cooperatively and proactively on hazard prevention and control, worksite analysis, training and management, and employee commitment.

As a result of the dedication of our employees to the VPP program, Piedmont’s employees in Anderson, S.C. have achieved the natural gas distribution industry’s first-ever VPP qualification.

Piedmont’s employees in Hickory, N.C. are expected to also achieve VPP qualification.

PiPEliNE SaFETyAs the provider of natural gas to more than one million customers in North Carolina, South Carolina and Tennessee, we extend our commitment to safety well beyond our employees. It includes a promise to our customers and communities that Piedmont Natural Gas is their natural gas expert, and we will continue providing safe and reliable energy.

With recent national events, many people have questions about the safety of natural gas and the facilities that transport it through our backyards and across our country. As one of the largest distributors of natural gas in the Southeast, Piedmont Natural Gas is working diligently every day on the safe operation, design and installation of our natural gas transmission system and local distribution networks.

Preventing Third-Party DamageApproximately 90 percent of the natural gas leak calls Piedmont responds to each year are the result of some type of third-party damage. Piedmont is mitigating this issue by educating the public on the importance of calling 811 to have the utility lines on their property located and marked before digging. “Call 811 Before You Dig” is a program that anyone can call to request the location and marking of the utility lines on their property.

Safety and Theft of Natural GasSafety is the driving force behind Piedmont’s program to prevent the theft of natural gas. We actively work to establish and maintain relationships with other utilities and law enforcement divisions in our service territory to combat the theft of natural gas. People who steal natural gas create unsafe conditions for everyone. Piedmont Natural Gas is committed to doing our part to locate, stop and charge natural gas thieves.

Recovering the money associated with stolen natural gas also helps to keep customers’ bills lower and reduces the cost of operating a safe delivery system.

we will pursue excellence in customer service and in our business operations

Operational excellence is the key to serving as good stewards for our customers, and we actively pursue this as one of Piedmont’s business objectives. Piedmont Natural Gas researches, designs and implements the policies, best practices, procedures and programs that are proven to deliver reliable, high-quality experiences for our customers.

CuSTOmEr SErviCEOur employees excel at providing great customer service 24 hours a day, 365 days a year, and we do it by identifying problems and then solving them quickly and accurately. As a result, Piedmont has an 85 percent average call resolution rate, meaning we successfully resolve the issues behind 85 percent of customer calls during our initial interaction with them.

In addition, an impressive 85 percent of our customer calls are answered in 20 seconds or less, reducing the likelihood that customers will become frustrated by lengthy hold times.

Expertise in the FieldIn 2010, Piedmont Natural Gas took a different approach to the light up season - the time when the weather cools and a large number of customers call into our call centers to request reconnection of their natural gas service. We proactively reached out to these customers through outbound calls, bill inserts and direct mail. Due to our efforts, we reduced by half the number of days customers had to wait for service during this busy time.

FACTA Identity Theft Red FlagsPiedmont Natural Gas has satisfied, ahead of schedule, all-new mandates required for the Fair and Accurate Credit Transactions Act (FACTA) Identify Theft Red Flag compliance. We accomplished this as part of our ongoing commitment to protecting customer data and doing our part to prevent identity theft.

Our program includes a team that conducts regular audits regarding the protection of our customers’ key identifying information throughout Piedmont’s entire business process. This includes strict identity verification procedures, evaluations of service provider contracts, ongoing training and a Red Flag system that alerts us of specific activity that could indicate identity theft.

iNNOvaTivE SOluTiONSPiedmont Natural Gas is the trusted energy provider to more than one million customers, all of whom rely on us to be their energy experts. It is our responsibility to provide the solutions that will help them become more energy efficient and use resources wisely.

Energy Efficiency InformationEnergy efficiency programs result in lower costs for consumers, lower emissions and reduced consumption of natural resources. Piedmont has multiple programs in place in North Carolina and South Carolina, and we actively seek programs in Tennessee. Our current programs include:

North Carolina:

>> Residential low-income energy efficiency program>> Commercial non-profit energy efficiency program>> Equipment rebate program

South Carolina:

>> Customer education program>> Residential low-income energy efficiency program>> Equipment rebate program

“From the first day since we ordered our service for a new gas tankless water heater, your service techs went out of their way to be the friendliest people we have ever met. They accommodated anything that we asked for, always with a great big smile and a wonderful attitude. Their responses to our requests have always been prompt, courteous and effective. These gentlemen are real assets to your company, so much that it has prompted me to write this letter in appreciation of all their valuable assistance.”

Residential CustomerElizabeth City, N.C.

Appliance Sales and ServicePiedmont recently introduced a new unregulated program, called Service Plus, through which we repair and sell natural gas products and appliances. This program gives us an opportunity to educate consumers and businesses about the environmental advantages of natural gas appliances.

Home WarrantiesPiedmont has partnered with HomeServe (USA), an independent company, to offer warranty plans to natural gas consumers.

Natural Gas VehiclesPiedmont continues to work within the natural gas industry to educate customers and the public about compressed natural gas (CNG) as a superior alternative fuel source. Natural gas is an abundant domestic resource with the potential to displace vast quantities of imported oil.

A CNG engine runs so cleanly that owners can skip every other oil change in a normal maintenance cycle, and it has much lower tailpipe emissions than a gasoline or diesel engine. Based on current prices, CNG ranges from $1 to $2 per gallon equivalent cheaper than gasoline and diesel (depending on local fuel taxes and market factors).

Benefits of CNG versus Gasoline (Source: The U.S. Environmental Protection Agency)

> Reduces carbon monoxide emissions 90%-97%

> Reduces carbon dioxide emissions 25%

> Reduces nitrogen oxide emissions 35%-60%

> Potentially reduces non-methane hydrocarbon emissions 50%-75%

> Emits fewer toxic and carcinogenic pollutants

> Emits little or no particulate matter

> Eliminates evaporative emissions

fIGURe 4.1

More CNG vehicles are available every year, and home-fueling units are available to consumers. We are beginning to actively market CNG and make it more widely available across our service areas, focusing on return-to-base fleets, both large and small. As the first step in building a network of fueling stations that anyone can use, we are making our fueling stations for Piedmont CNG vehicles available for public use.

Piedmont currently has operational public fueling stations in Charlotte and Greensboro, N.C., Greenville, S.C. and Nashville, Tenn. The following CNG stations with public accessibility will be built by the end of 2012 at our district offices as shown in FIGURE 4.2.

we will empower and engage our employees

Piedmont’s employees are our greatest asset when it comes to providing quality experiences for our customers and creating value in our organization. We continually look for ways to preserve and even increase the benefits and development opportunities available to our employees, and one area in which we have excelled recently is our Wellness program.

WEllNESSNot only do we support our employees’ development opportunities and overall health, our Wellness program reaches out to the people they care about as well. From gym memberships to health risk assessments (HRAs), all of Piedmont’s employee Wellness programs are available to spouses, children and even retirees. Popular programs include:

>> Biometric screenings>> Online health risk assessment>> EMPOWERED health coaching

Employee “WEL Hours” A motivating factor in our wellness program is the “WEL Hours” employees earn for each wellness activity they complete. WEL Hours may be converted into extra vacation days.

As a result of this and other incentives, the number of employees participating in programs to earn WEL Hours increased 10 percent from 2009 to 2010. This participation has produced a healthier, more educated work force, which is good for Piedmont, our customers and our investors.

Wellness SuccessProof of our Wellness success is revealed in the numbers that measure our program. In addition to an increasing number of employees participating in activities to earn WEL Hours, data from our annual HRA shows that employees are engaging in more positive lifestyle changes and, as a result, are reducing their health risk factors.*

* To protect and respect the privacy of our employees, all health assessment data is collected, managed and presented to Piedmont Natural Gas by a third-party vendor. All results are reported collectively.

Improving Health risk Factors

> Prevalence of five or more high health risk factors Decreased from 10.9% to 6.0%

> Participants’ average number of risk factors Decreased from 2.57 to 2.15 risk factors

> Physical Activity: at least three days of moderate activity Increased from 53% to 59.6%

> Nutrition: consuming three or more servings of fruits/vegetables Increased from 58.3% to 70.7%

EmPlOyEE SurvEySPiedmont is committed to providing its employees with a work environment reflective of our values. Since 2004, we have conducted comprehensive biennial employee opinion surveys to measure how well we are meeting our commitment to integrity, respect, excellence, stewardship and health.

Nearly 90 percent (1,617) of Piedmont’s 1,800 employees participated in our 2009 employee survey. Their feedback revealed our successes and opportunities for continued improvement. Our employees perceive Piedmont Natural Gas as an environmentally conscious company focused on employee safety and providing above-average benefit packages. Additionally, for the third consecutive year, Piedmont ranked at the top for work force commitment - in the 99th percentile.

divErSiTyOne of our company values is “respect” for others, and as part of our commitment to respect, Piedmont formed a Diversity Council in 2008. The purpose of this 18-member group is to recognize and value diverse backgrounds, experiences, styles, approaches and ideas.

Diversity is now playing an ever-increasing role in Piedmont’s leadership development, internship and recruiting programs. In addition, Piedmont employees remain actively engaged with organizations that promote diversity through development opportunities and youth programs.

“It’s great to work with a company that is committed to improving the health and productivity of its work force through affordable benefits and comprehensive wellness programs.”

we will reduce our impact on the environment

Piedmont Natural Gas has a reputation for treading lightly in our communities, and our efforts have increased in recent years. We believe being good stewards of our resources is not only beneficial to today’s communities, but that it is also one of the ways in which we can make the greatest impact for future generations.

The Nashville site included the opportunity to preserve a portion of our property in coordination with the Tennessee Wildlife Foundation. Eighteen acres on our site are permanently set aside for preservation, including five acres of wetland area.

RecyclingSince Piedmont began operations in 1950, we have been part of a recycling program. Our goal is not only to comply with regulations, but also to proactively reduce our environmental impact. Our recycling efforts have grown beyond light bulbs and paper supplies to include water heaters, scrap metal and electronics.

Climax GlObal ENErGyIn 2011, Piedmont made an equity investment in Climax Global Energy, a privately held, alternative energy company that converts landfill-bound plastics into high-value synthetic oil for clean diesel, synthetic-lube and wax markets.

With its first commercial facility to operate in South Carolina, Climax Global Energy and its innovative solution for waste removal can create jobs and displace foreign oil. This will also add to the overall economic well-being of our communities, supporting Piedmont’s commitment to be a good steward.

we will reduce our impact on the environment

Our OPEraTiONS

Pipeline ProjectsWhen our engineers begin designing a pipeline, they are well educated about the land and the surrounding communities. During construction, our customers and our communities can rely on us to minimize the impact. This includes working with land owners to negotiate replacement of fences, trees and other items.

Piedmont’s Construction Department prepares the land for pipeline construction. This area is called the right-of-way, and Piedmont takes every possible step to respect the land and the surrounding communities.

The process begins with a cultural resources assessment, during which the Corporate Construction Department conducts research about the land and its history. This effort may also include a wetlands report and an environmental assessment.

Our FleetAnother area in which we have pursued increased effectiveness and cost savings is with our fleet of vehicles. There are approximately 900 vehicles in Piedmont’s fleet. As of this report, this number includes 30 natural gas vehicles in operation. Our short-term goal is to grow this number to 100 by the end of this year, with a long-term goal of having 250 natural gas vehicles in operation by the end of 2013.

In 2010, Piedmont purchased Ford’s Crew Chief platform, called Telematics, to monitor our fleet’s specific key performance indicators. Telematics currently is installed on 250 of our vehicles, with the goal being to install it on all Piedmont Natural Gas vehicles within five years.

Telematics offers Piedmont valuable automatic reporting that keeps us better informed about the real-time condition of our vehicles and encourages accountability among the vehicle operators. Our hope is that with better information will come decreased operating costs, less idling time and overall efficiencies.

Automated Meter ReadingAutomated Meter Reading (AMR) is an example of a meaningful sustainability effort that is adding value to Piedmont Natural Gas with happier customers, increased effectiveness and savings for the organization.

AMR is a process through which technology automatically collects consumption, diagnostic and status data from natural gas meters and then transfers that data to a central database for billing, troubleshooting and analyzing energy consumption.

AMR has reduced the number of vehicles needed to read meters, which has reduced our meter reading expense per customer. It also has increased the accuracy of our bills and the efficiency with which we collect billing data, significantly reducing the number of estimates required to address incorrect or disputed bills caused by human error.

Our PEOPlE

Paperless Board MeetingsLeading the way in our efforts to continue minimizing Piedmont’s impact on the environment, our board of directors has adopted an innovative “paperless” meeting policy. All board materials are now distributed electronically to each director, significantly reducing the need for printing.

Clean Air Works!Clean Air Works! is a program through which Piedmont encourages employees to be good stewards of our resources by altering commuting habits in favor of public transportation, walking, biking, telecommuting and carpooling.

Piedmont partnered with local government agencies in Charlotte, N.C. to establish the program in 2007, and since that time our employees have saved an estimated $44,755 in fuel and maintenance costs. With our continued active membership, Piedmont has contributed significantly to the overall success of the Clean Air Works! program in Charlotte and the surrounding areas.

we will develop strong communities

We know Piedmont’s success depends on the positive influence we have on our local communities, so we seek to maximize our impact through volunteerism, economic development activities and support from our Foundation.

NaShvillE FlOOd In May 2010, when severe flooding hit our service areas in Nashville, Tenn., Piedmont Natural Gas responded. In addition to financial support through our Foundation, our company and our employees took immediate action to offer supplies, assistance, information and even just the basic necessities.

Our employees, many of whom were directly affected by flooding, were on site every day providing fresh water, hot meals, replacement furniture and donations to anyone affected by the flooding, whether or not they were a customer of Piedmont Natural Gas. This is because we live and work in this community, so we were neighbors helping neighbors. Our team distributed approximately 2,500 hot meals and more than 55,000 bottles of water to flood victims.

Following these efforts, Piedmont suspended late fees and connection fees and offered expanded payment arrangements and options for customers who were flood victims in Nashville. We also offered a special zero percent financing program for qualifying Piedmont customers who needed to replace flood-damaged natural gas appliances.

“I am so grateful to work for a company that wants to do the right thing for our communities. We were there for the flood victims in Nashville because they are our neighbors and because it was the right thing to do. Through this experience, we worked together in a culture of caring that has resonated throughout the Piedmont family. I was appreciative to be part of this effort, and I’m very proud of my company.”

vOluNTEEriNGOur employees are actively engaged in our communities. In support of their dedication, Piedmont has made community participation another opportunity for our employees to earn points through our Rewards & Recognition program. The families and business owners we serve trust us to be an active and engaged member of their communities, and we believe our employees should be rewarded for accomplishing this year in and year out.

Our Leaders are InvolvedPiedmont encourages all senior leaders to serve on at least one local non-profit board of directors within our service area. This has resulted in service on 38 non-profit boards in North Carolina, South Carolina and Tennessee.

The relationships and opportunities resulting from this effort have given Piedmont unique, first-hand exposure to the needs around us, and we’ve been able to respond much more effectively to our communities.

GiviNGEach year, Piedmont budgets approximately 1 percent of our pre-tax profit for giving programs. In 2009, our Foundation and Corporate Contributions totaled approximately $2.3 million. In 2010, the total was just under $2 million. When compared to other utilities and energy companies during this same period, our median total giving (as a percentage of pre-tax profit) was higher.

Corporate Charitable ContributionsPiedmont Natural Gas also supports local communities through corporate contributions unrelated to our Foundation. Since 2006, Piedmont has nearly tripled our charitable contributions despite an economic recession that resulted in lower revenues.

Employee Matching GiftsThe Employee Matching Gifts program is a part of Piedmont’s corporate contributions that allows us to diversify our financial support of our communities. Employees who make a financial donation to a qualifying organization may apply for a matching gift. Piedmont will then match the employee’s gift dollar-for-dollar, up to $2,500 per employee per year. Piedmont matched more than $100,000 in 2010.

This program allows our employees to have a direct influence on the non-profit organizations that receive funding. This is important to Piedmont because we know we are investing in organizations that are important to our employees.

Share the WarmthIn 2009, Piedmont launched the Share the Warmth Round Up Program. This program gives customers the choice to allow Piedmont to round up their monthly natural gas bill to the nearest dollar. The resulting funds are then passed directly to approved agencies within each of our service areas for distribution to families who need help paying their energy bills.

Since the program began, more than 21,000 customers have chosen to enroll. This small effort has generated nearly $100,000 in annual Round Up funds. These donations, in addition to Piedmont’s $250,000 Share the Warmth contribution, have resulted in $350,000 in support for families in need.

ECONOmiC dEvElOPmENT Our focus on community involvement includes helping to build and maintain healthy, thriving economies in each of the communities we serve. Our community relations managers and our major accounts representatives work with local chambers of commerce, regional partnerships and community leaders to help bring economic growth to our communities, especially during tough economic times.

Piedmont Natural Gas has a strong reputation and a long history of operating with integrity and respect. Creating this sustainability report has given us a new lens through which to view our business practices and a comprehensive tool for communicating our activities to all our stakeholders.

Our long-standing commitment to operating our business based on a specific set of values and sustainable practices has been a major contributor to Piedmont’s continued strong performance. In addition to creating value in the form of returns to investors, our actions are allowing new and future generations of customers the opportunity to experience Piedmont Natural Gas and the benefits of the energy we provide. Our work in local communities, our investments in energy education and our dedication to responsible environmental practices convey strong messages to current and future customers who will not only seek to use natural gas in their homes, but also will value it as a clean, reliable and domestic energy source.

Our values of integrity, respect, excellence, stewardship and health are the driving forces behind these efforts. Using these values as our guide, we operate an organization that places significant importance on ethics and our role as stewards of our communities, the environment and our shareholders’ investments.
