I want to know the answer to the following question:
What type of container can be used to transport draft beer, and is better for the environment that a bottle?
All the background I'm provided with is that "A life cycle study of one beer brand, including grain production, brewing, bottling, distribution and waste management, shows that the CO2 emissions from a 6-pack of micro-brew beer is about 3 kilograms (6.6 pounds).". Is that enough to answer the question?
