The world’s population is expected to grow by nearly 20% from 7.4B to 9B by 2050. This growth will substantially increase food production requirements with estimates that production will need to increase by as high as 70 percent to meet demand.  To hit this level of production, food and beverage industry will need to overcome operating with lower yields and increased production costs caused by climate change. Interestingly, the food and beverage industry is a key contributor to the phenomenon which stands to hurt their profitability in the long-run. The top 10 companies – including PepsiCo – emit 263.7 million tons per annum of GHGs which is the equivalent of being the 25th most polluting country in the world. 
PepsiCo is a large, multinational player in the industry. The company generated more than $63B in net revenue in 2015 with 22 brands like Frito-Lay, Pepsi-Cola, Quaker, and Tropicana.  Their brands are leaders in key categories (e.g., Gatorade, #1 sports drink, Quaker, the #1 hot cereal, Sabra, the #1 hummus) and are well-positioned for continued growth. Climate change poses detrimental risk to PepsiCo’s supply chain by limiting availability of key natural resources required for its product.
Supply and Demand Effects of Client Change
Agricultural raw materials from suppliers are the primary input for PepsiCo’s products and they are being impacted by climate change a few key ways. Firstly, agriculture uses a substantial portion of the world’s available freshwater supply and water availability is becoming increasingly limited. There is also an increasing prevalence of shocks to the systems like storms, floods, drought, and shifting pattern, which cause crop failures and supply disruption.  Some other issues caused by climate change which impact agriculture include changes in average temperature, rainfall, soil quality, and pest / diseases.
Climate change regulation also poses a threat to PepsiCo’s business model. Governments are seeking creative ways to reduce global warming. For example, San Francisco’s mayor recently banned water bottle purchases due to the amount of oil and carbon dioxide emissions required to produce the plastic bottles. This directly impacts the demand for PepsiCo’s products since it has Aquafina as part of its portfolio. Additionally, government regulation may directly impact operating costs when governments choose to tax or set limits for greenhouse gas emissions.
Performance with Purpose
Core to PepsiCo’s approach is its Performance with Purpose strategy, which the company describes as “our goal to deliver top-tier financial performance while creating sustainable growth in shareholder value.”  Moreover, according to Indra Nooyi, Chairman and CEO, the “strategy is built on sustainable business practices that optimize our near-term operating efficiency and profitability while ensuring that we are well positioned to deliver long-term business growth.”  The strategy has three different focus areas (Product, Planet, and People) and over the past ten years since its launch has made significant progress towards reducing its contribution to climate change and has developed new technology to help suppliers increase their yield.
Notable operational improvements to reduce their carbon footprint include:
• Reduced water use per unit of production by 25.8%, exceeding their goal of 20%, and reduced costs by $80M over five years
• Provided access to safe water to 9 million people through PepsiCo foundation
• Improved energy efficiency by 18% and absolute GHG emissions by 4%
• Reduced packaging material. 
One example of PepsiCo’s contribution to the supply side is with the potato farmers in water-stressed UK. They developed i-crop technology with Cambridge University and employed different irrigation method to halve water use and cut GHG emissions by 50% since 2010. 
PepsiCo’s primary goals for 2025 as part of Performance with Purpose is to:
• Improve water-use efficiency by 15% among direct agricultural suppliers in high- water-risk sourcing areas
• Reduce absolute GHG emissions by at least 20% across value chain by 2030
• By 2020 only purchase HFC-Free Equipment in the U.S. 
This shift to focus on improving the efficiency of its supply side will significantly reduce PepsiCo’s exposure to climate change risk.
Despite considerable focus on sustainability as part of its Performance with Purpose strategy, PepsiCo has come under scrutiny for its simultaneous funding of lobbying groups and politicians described as “climate deniers,” who oppose climate change regulation.  PepsiCo has the potential to be a true industry leader and should focus on ensuring that its corporate actions and messaging is consistent with the work its done on the sustainability front. According to Oxfam, “if each of the Big 10 companies made the same commitment to cut emissions from agriculture as PepsiCo UK, together they could save an extra 80 million tons of CO2e compared to business as-usual by 2020.”  Moreover, the company should critically examine whether the targets it has set for itself are aspirational and will protect its future profitability.
