This change has avoided over 1,650 tons of carbon emissions. In 2011 Air Wick® launched a ground-breaking aerosol product, using compressed air instead of butane, avoiding 20,000 tons of CO2 emissions during the year. Air Wick Flip & Fresh™ saves more than 10,000 tons of carbon, compared to traditional packaging. The product contains only fragrance oil and provides many doses per consumer unit with no propellant, heavy gadgets or batteries, minimizing the carbon footprint per dose. RB was able to achieve its Carbon20 goal eight years in advance by evaluating the entire lifecycle of each product through sourcing, manufacturing, distribution, use and disposal. The biggest impacts have been in consumer use (68.5% of the total footprint) and raw materials and packaging (23%). Over 5,750 tons of carbon emissions were avoided in 2011 due to various process improvements across RB's US-based manufacturing facilities.
