Abstract: Researchers have positioned renewable energy as sustainable and able to mitigate environmental issues associated with fossil fuels. Further, sustainable initiatives have been offered as a point of differentiation for brands. In order to reap the benefits of such differentiation, managers must communicate the initiatives to relevant stakeholders. The research question guiding the current investigation thus was: What is the communication by Canadian sport stadium operators to calls for sustainable initiatives, specifically in the area of renewable energy? The examination included the 15 sport stadiums that hosted a professional team in Canada and their web-based stadium communications on renewable energy (SCORE). Understandings and competencies in renewable energy are proposed as a new function of sport stadium management; communication of these competencies is seen as a key point of differentiation and best practice.
The world economy is dependent upon energy from fossil fuel sources to meet its needs, and ensuring a stable source of energy is a growing concern. The consumption of fossil fuel energy from traditional sources such as oil, coal, and natural gas however generates pollution, such as greenhouse gases. This pollution issue “is by definition global” , involving every business sector, including sport. In this context, the environment should be considered a primary stakeholder of sport and sport sustainability should be a managerial priority . This sector, thus, provides the focus of the current investigation.
A transition to renewable energy has been noted as necessary to meet a “critical need…and overcomes various problems associated with the existing power system” . Indeed, renewable energy can help to mitigate the greenhouse gas situation and can be used to offset the growing issues associated with declining oil production and increased difficulty with respect to extraction. Importantly, technology exists today to meet the call for renewable energy. Renewable energy is part of the solution to reduce dependence on fossil fuels by 70 percent by 2040 and offer savings of nearly $5.5 trillion per year . Currently, the contribution of renewable energy to the world’s energy needs has been positioned as high as 15%–20% . This contribution however “is expected to increase to 60% by 2070” . Understanding renewable energy in all sectors of society is, thus, important to reach the predicted need to reduce our demand for fossil fuels.
Environmental sustainability was defined by The United Nations’ (UN) Brundtland Report as safeguarding the natural environment for current and future generations . One conceptualization of environmental sustainability includes “the promise of … limitless pollution-free energy” . Here, the Organization for Economic Co-operation and Development predicted the years 2010 to 2020 as being important in this promise and “could prove to be a watershed [time period] in the transition of energy systems” . As organizations embrace this transition a myriad of positive results could occur; one such outcome includes enhanced organizational brand perception. Communication of renewable energy initiatives to the numerous stakeholder groups associated with an organization therefore should be a managerial priority. Indeed, the prioritizing of sustainability communications as a tool for shaping brand perceptions has been acknowledged before [9,10].
Historically sport organizations have relied on the media to disseminate organizational information. Given the advances in technology however there now exists “unique and distinct advantages for sport entities because they are able to communicate unfiltered messages directly to consumers” . This direct access to consumers provides sport managers with a new and profound way to manage the brand. It appears that an understanding of brand management is worthy for any sport manager, including those responsible for sustainability initiatives; thus a brief look at brand theory will follow.
It has been noted that whenever a “brand interacts with, and makes an impression on, customers, employees, and other stakeholders”  brand perceptions are forged. Indeed, a brand’s equity is derived from the totality of perceptions that individuals hold regarding the brand . Over the past two decades, authors have focused attention on managing perceptions through building brand awareness, managing opinions on quality, and promoting loyalty [14,15]. Indeed, brand managers must take control over every organizational touch point to manage how the brand is perceived. Indeed, “utilizing all organization-to-stakeholder communication channels (i.e., web communications) to promote brand-building initiatives could assist in enhancing brand loyalty” .
The purpose of the current study, thus, was to enhance understandings of the web-communications of renewable energy initiatives at professional sport facilities in Canada. The significance and managerial implications of such an investigation are threefold. Either, (1) facility managers are not currently engaged in renewable energy initiatives; (2) facility managers are engaged in renewable energy initiatives but are missing brand-building opportunities by failing to communicate their contribution to sport sustainability; or, (3) facility managers are engaged in both renewable energy initiatives and brand-building endeavors. Here, sport facilities falling into one of the first two categories risk potential brand erosion. Thus, the research creates, in part, an audit of the communications concerning renewable energy initiatives currently being implemented at Canadian sport stadiums.
The researchers of the current study were guided by the research question: What is the communication by Canadian sport stadium/facility operators to the call for sustainability, specifically in the area of renewable energy? Here, Horne notes that sport facilities are “part of the legacy of sport…both positive and negative” .
The remainder of this paper will progress as follows: first, the role and primary sources of renewable energy will be introduced. This will be followed by a discussion on sport and environmental sustainability. Next, a review of the methods utilized in the investigation will be offered. Research data on Canadian sport stadiums and renewable energy will then be presented and discussed prior to the study’s concluding section.
1.1. Renewable Energy
Traditional renewable energy sources include solar, wind, biomass, and geothermal energy. It is also important to note that there are additional, less conventional sources of renewable energy. For instance, a mechanism placed inside a soccer ball can produce energy from the vibrations generated as it is kicked. While innovative supplies of renewable energy certainly are noteworthy, the focus of the current investigation is on the contemporary, renewable energy sources including solar, wind, biomass, and geothermal. Purchasing of carbon offsets will also be considered in the context of renewable energy. While not a strategy for generating renewable energy directly, in this manuscript, an organization purchasing offsets is seen as being involved in renewable energy as they are providing foundational support for renewable energy projects.
1.2. Sport, the Environment and Energy Usage
“Major sports events consume considerable amounts of electricity, much of which is produced by burning fossil fuels, such as coal and oil” . Indeed, the environmental impacts of large-scale sport events have come under scrutiny. For example, a major sport event, such as the FIFA World Cup of soccer, has the energy impact equivalent to 3 million kilowatt hours of energy (similar to the energy consumption needed to meet the demands of 700 household’s annually in Europe) . Further, sports such as skiing [19,20], ice hockey , and golf  have also been noted for their impact on the environment. Emery indicates that an “outward looking global focus of more sustainable management practice”  is a desirable goal. Here, programs have been developed to stimulate and guide the adoption of environmental activities within organizations, including renewable energy initiatives. For instance, the United States Green Building Council manages the Leadership in Energy and Environmental Design (LEED) program throughout North America. Additional examples include the European Eco-Management and Audit Scheme (EMAS) as well as the Ecology Energy Saving, Waste Reduction and Health (EEWH) in Taiwan. Thus, while attention to the environment has now proliferated into management discussions at major sport organizations and “teams are increasingly recognizing the value of sustainability initiatives” , there is much more to be done. For example, an analysis of 21 sport-related journals published from 1987 to 2008 determined that there was a low level of research on sport and the natural environment . The authors of this manuscript thus proposed a multiple case study to create, in part, a preliminary audit of Canadian sport stadiums’ renewable energy initiatives based on their web-site communications. Here, Canadian sport facility managers have been challenged to make their stadiums world leaders “in the efficient and effective use of energy and resources” , including options of renewable energy. Further, communication of sport sustainability initiatives (i.e., renewable energy) could be viewed as an instrument for enhancing a brand’s equity. For these reasons the current investigation of value.
This research involved a multi-case content analysis of major Canadian sport stadiums’ web-based communications concerning renewable energy. Content analysis was described as “a research technique for making replicable and valid inferences from texts (or other meaningful matter) to the contexts of their use” . The methodological framework for this content analysis was based upon an adaptation of existing works [26,27]. Data collection included steps that outlined the sample, the unit of text, the coding themes and subthemes. Data analysis included steps that involved outlining the process, the analytical factors, and the coding mode. Each will be discussed in more detail next.
2.1. Data Collection
The multi-case strategy involved relevance sampling. To be considered a major sport facility in this manuscript, the facility must be home to a team in one of the following professional sport leagues: the National Hockey League (NHL), the Canadian Football League (CFL), the National Lacrosse League (NLL), the National Basketball Association (NBA), Major League Soccer (MLS) and Major League Baseball (MLB). The sample is outlined in Figure 1.
It is important to note that one sport facility, the Canad Inns Stadium in Winnipeg, Manitoba was eliminated from the study due to it being in a transitional situation. This facility was in the process of being sold and demolition plans were underway. Also, the Montreal Impact did not join MLS until the summer of 2012 and, therefore, their home facility was not included in this study. There were, thus, 15 sport stadiums under examination.
To begin, data on the architect, the year the facility opened, the owner and seating capacity was collected for each facility. Next, each unit of text consisted of the web-based communications concerning renewable energy at the sport stadiums listed above; communications had to be posted before 1 January 2012. The source of communications was the website for each sport facility. These communications are now referred to as Stadium Communications on Renewable Energy (SCORE).
There were two coding themes derived from an adaptation of the environmental measurement tool called the Sport Event Environmental Performance Measurement (SE-EPM) . The themes included the environmental operational performance and the supporting environmental organizational system. The sub-themes within the environmental operational performance theme included embracing renewable energy strategies, environmental disclosure, measuring, tracking, quantification and comparability of disclosed information, and the level of renewable energy utilization. The sub-themes within the environmental organizational system theme included environmental policies, programs, targets, funding, auditing, education and the implications of renewable energy. Further, the study was open to emergent themes.
It is important to note that many of the sport stadiums had environmental programs, such as the installation of building automation systems to ensure energy savings and the use of energy efficient light bulbs. In this manuscript, however, these types of programs were considered to be energy saving programs and not renewable energy strategies. Also, some facilities had major installations, such as the BC Place roof panels that were made of Ethylene Tetrafluoroethylene (ETFE) that consisted of a semi-transparent material to allow the transmission of natural light into the stadium from the roof; these panels were noted to save over 20 percent of the stadium’s annual energy costs . Again, these types of major installations were considered energy saving activities rather than renewable energy initiatives. This research focused only on the communication of renewable energy initiatives for the stadium specifically, and not the tenants of the sport stadiums—even if the tenant supported renewable energy or other sustainability endeavors, such as the Montreal Alouettes. Indeed, this team was noted to “have become the first Canadian professional team to go carbon-neutral” ; “the club will annually offset 400 tonnes of CO2”. Tenants or clubs in the four major North American team sport leagues, while outside the focus of this study, have been previously discussed .
2.2. Data Analysis
The data were analyzed separately by two of the researchers. The data analysis boundaries were set by the analytical factors stated in the SE-EPM . The coding mode in this study involved human coding with a manual search of the web-based communications. The two researches each analyzed the data separately and then held multiple discussions to ensure familiarity with the themes, subthemes, coding requirements and then to review and determine their agreement concerning the results.
3. Results and Discussion
In this investigation, 15 major sport stadiums that, in 2011, were home to Canadian professional sport teams from the NHL, CFL, NBA, NLL, MLS, and MLB were examined. The examination involved the stadium communications on renewable energy (SCORE) posted before 1 January 2012. Two themes, the environmental organizational system and the environmental operational performance and their sub-themes with respect to renewable energy, provided the focus for the investigation.

To begin, the median age of the stadiums was 28 years; the average age was 34.73 years; and the stadiums’ age range extended from 4 years (BMO Field) to 97 years of age (Percival Molson Memorial Stadium). Stadiums under the age of 20 included the MTS Centre (7 years of age), Air Canada Centre (12 years of age), Scotiabank Place and Bell Centre (both 15 years of age), and Rogers Arena (16 years of age). The older stadiums in the examination included Ivor Wynne Stadium (81 years of age) and Mosaic stadium (75 years of age).
The stadium ownership was spread across six ownership types. A total of 33.33% of the stadiums were owned by an entertainment company, 26.66% were owned by a city, 13.33% were owned by a university, 13.33% were owned by a property management company; 6.66% were owned by a communications company and 6.66% were privately owned. Seating capacity ranged from 15,015 to 60,000 with the average being 28,593 seats.
In the environmental operational performance theme, the baseline results indicated that 4 (26.66%) of the stadiums communications did reveal involvement in renewable energy strategies, including: Air Canada Centre, BMO Field, BC Place Stadium, and Rexall Place. In the first sub-theme on embracing renewable energy strategies, the communications revealed that the conventional renewable energy strategies being utilized included: a wind energy project along with a pilot study in solar energy at BMO Field, a biomass/biofuel energy project at the Air Canada Centre, and the purchase of offsets at BC Place. Further, an emergent theme in non-conventional renewable energy strategies involved a heat exchange strategy at Rexall Place and a “Deep Lake Water Cooling System”  at the Air Canada Centre. It is apparent that the stadiums involved in renewable energy were utilizing both conventional and non-conventional strategies.
At BMO Field, wind turbines had been positioned on the surrounding grounds called Exhibition Place. These turbines produced approximately 1 million kilowatt hours per year in 2009 and 2010 that was fed into the local grid. Additionally, recently, these same grounds instituted “a pilot project for a 100 kilowatt photovoltaic power-generation plant and a smaller combination solar photovoltaic/thermal plant” . Difficulties arise concerning the specific sport stadium renewable energy activities concerning wind energy and the pilot project in solar energy as the sport facility is encompassed within a larger complex or grounds. In 2010, however, Exhibition Place communicated an aim to utilize 100% renewable energy at its related facilities; this includes BMO Field. This aim was interpreted to mean that BMO Field was involved in a transition to renewable energy with wind energy usage and the pilot study on solar energy. Communications, however, have not been posted that confirm the aim for 100% renewable energy had been met at BMO Field or the adjacent facilities; this is interpreted in this manuscript therefore as not having been met at this time.
A biomass energy project at the Air Canada Centre was communicated as involving fryer oil that was converted into biofuel. Additional information, however, was not revealed concerning the process for converting the oil, the amount of biofuel generated and its use. Interestingly, in June 2012, Air Canada, the national airline with the naming rights to the sport facility, utilized recycled cooking oil in an airline test flight from Toronto to Mexico City. This flight was noted as “using 50 percent biofuel… [and] was expected to generate 40 per cent fewer emissions” .
The BC Pavilion Corporation that manages BC Place “purchased 6620 tonnes of carbon offset, worth 165,500.00 CAD to become carbon neutral for the 2011 calendar year” . This purchase activity represented participation in a transition to renewable energy with the support of renewable energy strategies.
Rexall Place was noted as having a heat release strategy whereby “heat from hot ammonia in cooling compressors…is recovered by generating hot water in the condenser. This hot water is transported and used to melt snow, which is required to load the Zamboni ice conditioning machine” . This heat exchange strategy, albeit interpreted by the authors of this manuscript to be at a low level, did however represent a transition to renewable energy. The Air Canada Centre established a “Deep Lake Water Cooling System”  that has been in operation since 2004 and involved a series of three pipes extending five kilometers into Lake Ontario. This 170 million-dollar (U.S.) cold water project “draws water from three miles (five kilometers) offshore and 270 feet (83 meters) down, where the temperature of Lake Ontario stays near 39.2 degrees Fahrenheit (4 degrees Celsius) throughout the year” . This water is too cold to drink, however, as it is transferred “heat exchangers allow the lake water to cool a…self-contained water circulation system”  generating an air conditioning system. This transition to a cold-water cooling system as a renewable energy strategy was interpreted as a unique emergent strategy in renewable energy for summertime air conditioning for stadium situated near cold water sources. None of the other stadiums communicated that they had utilized this strategy; thus, this is interpreted as advancement in renewable energy at Canadian sport stadiums.
Each SCORE was then examined for sub-themes, including environmental disclosure, measuring and tracking, and quantification. None of the communications for sport stadiums utilizing renewable energy specifically indicated that their energy program was being tracked, measured and/or quantified. The low level of environmental disclosure meant that comparability was limited. The cost to implement each renewable energy strategy, the cost and energy savings expected over time, and, importantly, how these strategies aided to safeguard the natural environment was not available for this study due to a lack of data in the web-based communications.
Comparisons, however, were possible based on the types of renewable energy strategies being utilized, the age, size and the site of the stadium utilizing renewable energy, along with the architects. It was noted that the age of stadiums utilizing renewable energy included: Air Canada Centre (12 years); BMO Field (4 years); BC Place (28 years) and Rexall Place (37 years). Clearly, age is not a determining factor for renewable energy use as young stadiums, as well as older stadiums, were involved in renewable energy. Interestingly, the Air Canada Centre won the 2011 Sustainability Award given out at The Stadium Business Summit “for meeting the sustainability challenge with practical, cost-effective and community-focused solutions… not easy in a busy building that is more than a decade old” . Renewable energy, thus, was not relegated only to new stadium builds in Canada.
The four stadiums with renewable energy utilized 3 different architectural firms indicating that, in this sample, the firm is not a deciding factor concerning the institution of renewable energy initiatives. The Air Canada Centre and BMO field utilized Brisbin Brook, Beynon Architects; BC Place used Stantec Architecture Ltd.; and Rexall Place used Manasc Isacc Architects.
Overall, the results within the first theme on environmental operational performance illustrated that the stadiums set their own direction concerning renewable energy strategies. No map emerged involving the development of a collective as the stadiums were not seen as working as a cohesive group to learn from each other and follow the same pathway to renewable energy. Also, interestingly, no cases of geothermal renewable energy were found. Further, it was noted that communications for comparability could be complicated as stadiums, such as BMO Field and BC Place, were situated within surrounding grounds and groups/organizations with respect to their renewable energy strategy. This meant that the specific sport stadium data on measured, tracked and the quantification of the renewable energy strategies for each stadium could be intertwined within broader data making quantification for future comparability difficult.
Next, the focus of the investigation moved to the second theme of analysis: the environmental organizational system including the environmental policies, programs, targets, funding, auditing, education and implications of renewable energy. Findings revealed that stadium renewable energy policies were non-existent within the communications. Further, communications on renewable energy strategies centered on announcing particular projects and did not outline full strategy or program details. Also, only one stadium was involved in communicating renewable energy targets. Exhibition Place, the grounds that house BMO Field, announced a target of 100% renewable energy; to be “leading the use of energy-efficient technologies” and “achieving energy self-sufficiency” .
The funding of renewable energy strategies was found to be a limited topic within the communications. Only BMO Field, situated within the grounds of Exhibition Place noted “establishing an annual ‘environmental’ capital budget” ; information specific to renewable energy plans however were not present. Additionally, discourse on auditing the renewable energy strategies was absent from the communications. Similarly, education was also not a topic within the communications.
The implication based on the data analysis for the two themes and their subsequent sub-themes is that a transition to renewable energy is underway at Canadian sport stadiums, albeit generally at a low level of commitment and at the early stages of transition, with the exception of BMO Field. This level of transition implied that renewable energy was recognized as an option, even if it is being instituted at a slow pace. This transition, however, is important as the Air Canada Centre, owned by MLSE, indicated that “energy is the largest component of MLSE’s footprint” .
Within the sport facilities that did not report a transition to renewable energy, there were communications that indicated a consideration concerning the concept of environmental sustainability. One example was the Bell Centre in Montreal, Quebec; this facility achieved LEED certification for existing buildings at the silver level and an ISO 14001 certification for environmental management systems . Another example was Commonwealth Stadium in Edmonton Alberta; stadium officials collaborated with the City of Edmonton and the Edmonton Eskimos in 2010 to initiate a “Green and Go” program that focused on reductions concerning environmental impacts of transportation and the utilization of a synthetic artificial turf. A final example is Ivor Wynne Stadium in Hamilton, Ontario that completed an energy audit in 2007. These facilities were not directly involved in renewable energy; however, they illustrated a movement in sustainability. The authors of this manuscript purport that it is logical for a movement in sustainability to be a precursor to the potential future involvement in a commitment to renewable energy.
This research sought understandings on the research question: What is the communication by Canadian sport stadium/facility operators to the call for sustainability, specifically in the area of renewable energy? The current research thus created, in part, an audit of the communications concerning renewable energy initiatives currently being implemented at Canadian sport stadiums. Here, the authors’ contention is that sport facilities failing to engage in or communicate renewable energy practices risk brand erosion. The examination involved 15 major sport facilities that were home to Canadian professional sport teams during 2011 from the NHL, CFL, NLL, MLS, NBA, and MLB and their stadium communication, posted on-line before 1 January 2012. This research acts, in part, as a preliminary audit on the communications by major Canadian sport stadiums concerning a transition to renewable energy.
Results indicated that renewable energy had emerged within the Canadian sport stadium landscape. A total of four (26.66%) stadiums, home to Canadian professional teams, were involved in renewable energy. The range of renewable energy projects included the following: one large wind energy project with an associated small pilot project in solar energy at BMO Field, a small biomass/biofuel strategy at the Air Canada Centre, and the purchase of renewable energy offsets at BC Place. Additionally, a small heat exchange strategy was utilized at Percival Molson Memorial Stadium. Importantly, the Air Canada Centre utilized a Deep Lake Water Cooling System for their air conditioning system that was interpreted as a cutting edge strategy that could lead the way for renewable energy for air conditioning for stadiums situated near cold water sources. Overall, the results revealed that the stadiums were heading in multiple directions with respect to renewable energy.
The level of renewable energy and its impact at the Canadian sport stadiums was interpreted to be in the primary stage. This interpretation was based on the fact that the communications of renewable energy strategies highlighted relatively small initiatives in terms of their potential production of renewable energy, with the exceptions of the wind project at BMO Field. Additional mitigation information was not discernible based on the lack of data within the communications. This included a lack of environmental disclosure, measuring and tracking, and the quantification that allowed for the comparability of disclosed information and, thus, the level of renewable energy utilization was not possible to establish at this time.
Future research is needed to advance understandings on stadium operators’ renewable energy initiatives. Communication of initiatives must be monitored to understand changes in stakeholders’ brand perceptions. Best practices for efficiency and effectiveness, trends, and leadership in sport facility renewable energy can then be established. Finally, long term studies are needed to answer the question: Will sport stadiums achieve predictions that renewable energy will meet 60% of the energy needs by the year 2070? And, if so, how will this be communicated? The answer to these questions remains to be seen.
