IPA Oskar Blues Craft BeerSee all questions about commodity
Hello my name is Lizzie and I’m your commodity consultant for today.
Thank you for your question, I have been doing some research and this is what I have found...
With regards to carbon footprint canned beer appears to have less of an environmental impact than glass,
This source suggests because IPA Oskar Blues beer is canned it has 30% less of a carbon footprint than a glass bottle (http://www.examiner.com/article/oskar-blues-great-beer-cool-cans). Whereas, this source suggests the reduction is even higher at 35% (http://www.beerinfo.com/index.php/pages/craftbeerinacan.html).
However, as always things are a bit more messy than this!
If your favourite beer is made in a land far, far away, like IPA Oskar Blues, it is perhaps best to choose cans. However, locally made beer in a glass bottle is better for the environment according to this source (http://www.davidsuzuki.org/what-you-can-do/queen-of-green/faqs/recycling/whats-better-for-the-environmentbeer-in-cans-or-bottles/)
Also it depends on whether you recycle your bottle/can after use, currently 97% of glass is recycled in Canada but only 80% of cans (http://www.davidsuzuki.org/what-you-can-do/queen-of-green/faqs/recycling/whats-better-for-the-environmentbeer-in-cans-or-bottles/)
Also, cans are lighter and that means transportation emissions are lower. Most cans contain about 40 per cent recycled aluminum, which is also good news. Recycled aluminum requires 95 per cent less energy and produces 95 per cent less greenhouse gas emissions than manufacturing new aluminium. (http://www.davidsuzuki.org/what-you-can-do/queen-of-green/faqs/recycling/whats-better-for-the-environmentbeer-in-cans-or-bottles/)
A point that supports glass is that canned beverages—beer, pop, infant formula, etc.—leach bisphenol-A (BPA) from their protective metal linings. BPA is a human-made chemical linked to breast and prostate cancer, and many more health concerns. (http://www.davidsuzuki.org/what-you-can-do/queen-of-green/faqs/recycling/whats-better-for-the-environmentbeer-in-cans-or-bottles/)
Here are some more links to further information about BPA if you are interested ....

Also it depends on the environmental ethics and commitments of the company of beer you buy from (that is if you support/believe in the idea of offsetting). Oskar Blues Brewery seems to get some good press for their environmental ethics. The brewery's CAN'd Aid Foundation has raised over $1.2 million for various environmental projects and nonprofits, and the new REEB Ranch bike retreat in Brevard, North Carolina is all about reconnecting with the great outdoors; guests can enjoy some of the best singletrack in the country in Pisgah National Forest, then have a beer down the road at Oskar Blues' East Coast brewery.
Here is another example of how Oskar Blues Brewery is trying to offset their carbon footprint - by donating drinking water (http://denver.cbslocal.com/2016/01/19/oskar-blues-donates-drinking-water-to-flint-mich-residents/)

What is the carbon footprint of this beer and is the taste worth such an impact?' It goes into more depth on some of the issues discussed!
Thank you for your excellent question,
