Carlsberg Group: Decarbonizing Draught Beer Custom Case Solution & Analysis

1. Evidence Brief: Carlsberg Group Case Extraction

Financial Metrics

• Packaging accounts for 40 percent of the total carbon footprint of a beer.
• DraughtMaster technology reduces the carbon footprint by up to 40 percent compared to traditional steel kegs.
• Draught beer represents approximately 15 percent of Carlsberg total volume but contributes a significantly higher share of profit.
• Traditional steel kegs require 10 kilograms of weight per unit when empty, while DraughtMaster PET kegs are significantly lighter, reducing transport emissions.
• Beer shelf life increases from 5-7 days in steel kegs to 31 days in DraughtMaster systems once tapped.

Operational Facts

• Traditional systems use added CO2 to push beer; DraughtMaster uses an air pump and a collapsible PET bag.
• The system eliminates the need for CO2 canisters at the point of sale.
• DraughtMaster kegs are designed for one-way use, removing the need for return logistics of heavy steel.
• The system requires specific proprietary tapping equipment installed at the bar or restaurant.
• Carlsberg operates in over 150 markets with varying degrees of recycling infrastructure maturity.

Stakeholder Positions

• Cees t Hart, CEO: Committed to the Together Towards ZERO and Beyond program, targeting net zero carbon emissions by 2040.
• Simon Boas Hoffmeyer, VP of Sustainability: Views DraughtMaster as a primary lever for Scope 3 emission reduction.
• Bar and Restaurant Owners: Value the extended shelf life and reduced waste but express concern over the storage and disposal of plastic PET kegs.
• Logistics Partners: Benefit from lighter loads and no return-trip requirements for empty steel.
• Distributors: Traditional distributors may resist the shift if their business model relies on steel keg maintenance and CO2 supply.

Information Gaps

• The exact capital expenditure required for a bar to convert from steel to DraughtMaster.
• The specific cost per liter difference between steel keg supply and DraughtMaster supply.
• Quantitative data on the current recycling rate of PET kegs in emerging versus developed markets.
• The impact of energy consumption for the DraughtMaster air pumps compared to traditional CO2 systems.

2. Strategic Analysis

Core Strategic Question

• How can Carlsberg achieve its 2040 Net Zero target by scaling DraughtMaster globally while managing the circularity of PET waste and overcoming value chain resistance?

Structural Analysis: Value Chain Lens

The transition from steel to PET shifts the bottleneck from logistics (weight and return trips) to waste management (circularity). In the traditional model, the steel keg is a reusable asset with a 20-year lifespan. In the DraughtMaster model, the keg is a consumable. This requires Carlsberg to move from being a brewer to a circular system orchestrator. The primary structural barrier is the lack of standardized PET recycling for industrial-scale kegs in many markets.

Strategic Options

Option 1: Aggressive Mandatory Conversion. Mandate DraughtMaster for all new contracts and phase out steel kegs in Western Europe by 2028. This maximizes carbon reduction and forces the market to adapt.
Trade-off: High risk of losing market share to competitors who continue to offer steel kegs to traditionalist bar owners. Requires massive upfront investment in equipment subsidies.

Option 2: Circular Service Model. Position DraughtMaster as a premium service where Carlsberg manages the entire lifecycle, including the collection and recycling of PET kegs.
Trade-off: Increases operational complexity and logistics costs. Requires building or partnering for specialized recycling infrastructure.

Option 3: Segmented Hybrid Approach. Deploy DraughtMaster exclusively for low-volume accounts where the 31-day shelf life provides the highest economic value, while maintaining steel for high-volume stadiums and large venues.
Trade-off: Dilutes the carbon reduction impact and maintains two parallel supply chains, increasing overhead.

Preliminary Recommendation

Carlsberg should pursue Option 2. The environmental benefit of DraughtMaster is negated if PET kegs end up in landfills. By taking ownership of the circularity, Carlsberg de-risks the transition for bar owners and secures its sustainability claims. This path aligns the profit motive (extended shelf life) with the sustainability mandate.

3. Implementation Roadmap

Critical Path

The success of the DraughtMaster rollout depends on the 90-day stabilization of the reverse logistics loop. The sequence is as follows:

• Month 1: Establish regional collection hubs in three pilot markets (Denmark, Italy, and Norway) to aggregate used PET kegs.
• Month 2: Launch the Green Rewards incentive program for bar staff to ensure kegs are compressed and sorted correctly.
• Month 3: Finalize contracts with specialized PET recyclers capable of handling the multi-layer plastic used in DraughtMaster kegs.

Key Constraints

• Recycling Infrastructure: Many markets lack the facility to process industrial PET kegs. Implementation is constrained by the speed of local waste management partnerships.
• Bar Space: The DraughtMaster system has a different footprint than traditional kegs. Physical space in small urban bars is a hard constraint for adoption.

Risk-Adjusted Implementation Strategy

To mitigate the risk of recycling failure, Carlsberg will implement a phased geographic rollout. Each market must pass a Circularity Readiness Audit before DraughtMaster becomes the primary offering. If a market lacks recycling capabilities, Carlsberg will deploy a temporary take-back program where empty kegs are backhauled on delivery trucks to central hubs, preventing local landfill disposal.

4. Executive Review and BLUF

BLUF

Carlsberg must transition DraughtMaster from a product sale to a circular service model to meet 2040 Net Zero targets. The 40 percent carbon reduction is the primary differentiator, but the plastic waste profile creates a reputational risk. Implementation should focus on taking full accountability for the PET lifecycle. This shift requires immediate investment in reverse logistics and recycling partnerships. The extended 31-day shelf life provides the economic justification for bar owners to accept the transition. Speed is essential to set the industry standard before competitors scale rival systems.

Dangerous Assumption

The most dangerous assumption is that existing municipal recycling streams can or will process industrial-sized PET kegs. These kegs are often treated as contaminated waste or are too large for standard sorting lines, meaning the carbon benefits are lost if the kegs are incinerated or landfilled.

Unaddressed Risks

Unconsidered Alternative

The team did not fully evaluate a Co-op Recycling Model. Carlsberg could invite competitors (Heineken, AB InBev) to share a standardized PET keg design and a joint recycling infrastructure. While this reduces competitive advantage, it solves the structural problem of recycling scale and reduces the cost of reverse logistics for the entire industry.
