Crown Holdings Sustainability Report: GHGs Down Since 2009

Crown report GHGsCrown Holdings, a major supplier of metal packaging products, has released its second sustainability report, covering fiscal years 2011 and 2012. Results include:


  • Combined direct and indirect GHG emissions per unit held roughly steady from 2010 to 2012, though down from 2009 levels – the exact numbers are difficult to reach from Crown’s charts.
  • The company says pressures on its GHG efforts included “new capacities in territories where GHG impact per kWh is higher, lower start-up efficiencies on those new lines, and increased production of non-standard can sizes (which typically run at slower speeds).”


  • Energy consumption per unit has trended very slightly downward since 2007.
  • Crown’s European beverage business implemented an energy management program at 14 plants that cut energy use per thousand cans by 5 percent from 2010 to 2011, and another 5.5 percent in 2012 versus 2011.
  • Its Mijdrecht, Netherlands plant reduced electricity used to generate compressed air by 20 percent.
  • Crown’s Asia Pacific Division found energy reductions of about 3 percent per 1,000 cans, from 2011 to 2012.

Waste and recycling

  • Total waste generation has seen slight decreases in the past few years. The company has also increased its generation.
  • Crown recycled 10,000 tons more material in 2012 than in 2010, though its waste recycled per unit stayed largely steady.
  • The company’s largest source of recycled material is scrap metal from the can manufacturing process.
  • Its Nocera, Italy food can plant reduced cleaning solvent use by over 45 percent and hazardous waste generation by over 70 percent, as well as lowering fugitive solvent emissions.

Material consumption

  • Material consumption in tons per billion units has declined very slightly since 2007.
  • Crown attributes the downward trend to optimization of coating and compound weights. The data accounts for conversion to non-BPA coatings, which generally require higher film weights.
  • Crown says it works on over 100 different lightweighting projects each year across its businesses.

VOCs and NOx emissions

  • NOx emissions per billion units have fallen steadily from about 3.9 tons in 2007 to about 3.4 in 2012.
  • The company says it cut NOx by minimizing downtime in the curing process, using more efficient oxidizers and optimizing heat recovery, among other measures.
  • VOC emissions fell from roughly 140 tons per billion units in 2007 to roughly 100 tons/billion units in 2012.
  • Crown says the reduction results from its use of water-based, higher-solids coatings, optimization of coating film weights and investment in more efficient control technologies, among other measures.

Data and reporting

  • Crown says the report follows GRI G3 Guidelines at Application Level C.
  • The company has transitioned from presenting total emissions and total use of raw materials to normalizing usage and emissions per billion units produced.
  • It uses a set of conversion factors to transform volumes for its range of different cans into 12 ounce aluminum beverage can equivalent volumes, which it calls “units.” Details can be found here.

Takeaway: The report summarizes many of the strategies and improvements that helped the company reduce its environmental impacts. But the relevant data can barely be discerned from the report’s poorly designed graphs. The report also does not address water consumption.
