Climate Change & Whisky: The Sobering Realities

Does Diageo, the producer of Johnnie Walker, Caol Ila, Talisker, Lagavulin, and Oban Scotch Whiskies, need to improve its sustainability practices?

Scotch whisky is Scotland’s largest export, contributing £4.0Bn to the country’s £27.5Bn (~15%) annual exports[1].  The primary ingredients in Scotch, which derives its name from Uisge beatha (“water of life”)[2], are water and barley; however, climate change trends are threatening not only the economic benefits of whisky, but also Scotland’s cultural heritage.  Global weather patterns are disrupting crop production and water cycles, both of which directly impact the production of whisky.  As the largest Scotch manufacturer with 36% market share[3], Diageo plays a leading role in ensuring sustainable whisky production; however, the company has recently come under scrutiny for its failures in championing sustainability and responsible business practices[4].


Exhibit-1: Diageo’s Cameronbridge Distillery (Leven, Scotland)

In 2013, Diageo’s Cameronbridge Distillery (Exhibit-1) emitted 134.2MM Kgs of carbon dioxide (“CO2”) into the atmosphere, leaving the facility as the 20th largest CO2 polluter in Scotland, mainly behind industrial manufacturing and energy companies like Scottish Power, which is Scotland’s largest emitter, releasing 7.4Bn Kgs of CO2[5].  That same year, however, William Grant & Sons (“Grants”), another whisky producer with 7% market share[6], released 184.2MM Kgs of CO2 at its Girvan distillery.   This difference is startling considering that Cameronbridge has an annual capacity of 100MM liters[7] and Girvan’s capacity is 110MM liters[8].  Given the vast quantities of CO2 ejected by energy and industrial manufacturing companies, one could argue that the likes of Diageo and Grants ought not to worry about their relatively small carbon footprints.  This viewpoint, however, is short-sighted.

Since 2013, Diageo has invested in improving its sustainability at its Cameronbridge facility.  The company made a £65MM investment in technology that now caters for 95% of Cameronbridge’s energy needs and which has made the distillery “the first distillery in the world to combine biomass combustion, anaerobic digestion and water recovery”[9].  The 2015 data shows vast declines at Diageo’s Cameronbridge distillery yet lackluster declines at Grants’ Girvan facility.  Diageo showed a ~40% decline in CO2 emissions and now ranks 26th with 81.0MM Kgs released.  Grants on the other hand has only reduced emissions by ~10%, but has increased in the rankings to the 14th largest polluter[10], despite support from Siemens on improving its sustainable practices[11].

Diageo has aligned itself with other organizations interested in climate change.  For example, the Scotch Whisky Association (“SWA”), a trade association that works to sustain Scotch’s role in global beverages, has also advocated for greater focus on environmental issues.  Recently, the SWA refreshed its Environmental Strategy (Exhibit-2), and although the SWA has no authority over the actions of Scotch manufacturers, the added presence of the trade body could help producers to strive to improve their sustainability practices.  Diageo is also a member of the Beverage Industry Environment Roundtable (BIER) which “works to reduce consumption, mitigate impacts and ensure sustainable continuity and future of the beverage sector.”[12]  Participating and collaborating with these entities will be helpful in enhancing environmental best practices at Diageo.


Exhibit-2: SWA Environmental Strategy Refresh (September 2016)

Diageo has continued to demonstrate its commitment to sustainability, with its recently completed Roseisle distillery generating ~50% of its overall energy need from onsite renewable sources[13].  Diageo is committed to improving its carbon footprint in Scotland, and has worked closely with the Scottish government and the Scottish Environmental Protection Agency to develop projects that reduce emissions[14].

Diageo’s public filings outline their global 2020 strategy for sustainability, which focuses on water stewardship, carbon, waste and sustainable packaging[15].  Diageo could go further in its efforts for sustainability and I would be interested to ask the company the following questions as they pertain to the production of Scotch: how can Diageo improve efficiency transporting raw materials to distilleries?  What efforts are Diageo making to cut energy usage during the production process?  Is unused water treated before being discharged into Scottish rivers?  What efforts are being made to use recycled paper for boxes and labeling?  The company clearly outlines its global vision, however, as Scotch is predominantly produced in Scotland, I would like to see more information about environmental efforts within Scotland.

The incentive for whisky producers to be bystanders in combating climate change is very high given the other polluters in Scotland (energy and industrial manufacturing) but diffusion of responsibility should come second to the sustainability of the system that gives Diageo the raw materials and allows them to manufacture in the first place.  As the market leader in the production and distribution of Scotch, Diageo needs to continue to lead by example, and to keep advocating for further environmental regulation in Scotland to ensure whisky continues to play a vital role in the Scottish economy for generations to come.

Student comments on Climate Change & Whisky: The Sobering Realities

  1. I just wonder ‘why’? When I’m sipping my old fashioned, I’m generally not thinking about the environmental effect of what I’m drinking. Scotch is an integral part of our heritage, but I think people care more about that than whether they are helping the environment. Especially when it comes to grabbing a drink in Shoreditch House.

  2. Alex, I don’t see it as a marketing effort. I agree that they probably wont be able to sell much more whisky by advertising how much less they pollute than competitors, but that isn’t the point. To really combat climate change, we have to address it as universally as we cause it. Every industry and consumer needs to be aware of it, and be ready to make some sacrifices to prevent it. It’s great to see such a large Scotch producer doing its part. The last thing that comes to mind when I think of Scotch is climate change. Having never seen a distillery, I have a quaint image of old stone buildings in the mossy countryside, filled with copper pot stills. Taking the initiative even when consumers like me don’t recognize the need shows altruistic concern and should be applauded.

  3. I like the way Diageo is collaborating with other organizations to lead the charge in promoting environmental best practices. It reminds me of IKEA becoming a founding member of the Forest Stewardship Council (FSC) to help solve the problem of deforestation. These large and influential organizations have a duty to evolve as environmentally conscious entities as they continue to heavily influence environmental outcomes.

  4. Given that scotch whisky is Scotland’s largest export, I would have been curious to learn more about how Diageo’s export chain affects the environment. Are Diageo and other brands like Grants significantly understating their CO2 footprint by hiding CO2 emissions in their distributors’ ledgers?

    To the debate above about why Diageo has pursued emissions reductions, I’d be interested to see if the investments they’ve made have helped them lower the costs of producing scotch whisky.

    1. Thanks for your comment Eric, you raise a really interesting point about Diageo’s export chain. I am sure it’s an issue that most global CPG companies face, and I would be fascinated to learn more myself. As I research this topic, I will share my findings with you…maybe over a Scotch!

  5. As a consultant, one of my favorite projects was with an alcoholic beverages company in Mexico. On thing that I remember about the industry are its high margins, which give these companies some freedom to invest in special initiatives. In addition, the target market for scotch tends to be people with a higher socioeconomic background, who tend to appreciate sustainability efforts.

    I believe that Diageo can leverage this efforts for brand building purposes. One example that comes to my mind is Stella Artois (AB InBev) supporting the foundation to help raise awareness of the water crisis issue.

  6. This is a great post that highlights an interesting question. What will be the ultimate impetus for highly impactful climate change efforts: Government regulation or strict self-policing? The former seems more likely, but countries like Scotland, with a delicate ecological balance and entire industries that depend heavily on the natural environment, may demonstrate otherwise. My personal view is it will be some hybrid. See
    for American companies that have voluntarily made commitments to climate change mitigation in response to the US American Business Act on Climate.
