A significant step forward in sustainable premium packaging, we have reduced the carbon footprint of Suntory's iconic Knob Creek bourbon bottle without compromising the weight, distinctive design, or character that make it instantly recognizable. 

A complex shape with sharp angles, embossing, and a practically optimized weight that challenges the capabilities of premium glassmaking. Even with these demands, Saverglass significantly reduced the bottle's environmental impact by optimizing both how and where the glass is made. 

Key achievements from the initiative include: 

• Zero Weight Reduction: The bottle retains its full, hefty feel in hand, preserving the premium tactile experience consumers expect. 
• 100 Percent Low Carbon Energy: Transitioning fully to low carbon energy sources for production, supported by nuclear Power Purchase Agreements initiated in 2023 and fully integrated by 2025, drove an estimated 36 percent reduction in total carbon dioxide emissions. 
• Increased Recycled Content: Production shifted from using zero recycled material to incorporating 15 to 20 percent Post Consumer Recycled glass cullet. 
• Uncompromised Aesthetics: The final product is visually indistinguishable from previous iterations. 

The project highlights how advanced manufacturing techniques and renewable energy transitions can deliver drastic carbon reductions in luxury spirits packaging without compromising on brand or product quality.
