Based on Julie’s Bicycle research that suggested that CD packaging was responsible for a significant proportion of the music industry’s carbon emissions, JB convened a working group of industry, science and specialist experts under the leadership of Tony Wadsworth, to scrutinise the science and the business of CD packaging and come up with some solutions. Research commissioned into the impacts of CD packaging found that the recording industry could reduce its packaging emissions by up to 95% by switching from the plastic jewel case to card wallets. Research into consumer preferences and manufacturer capacity supported the recommendation to switch from plastic to card. Based on the research, large parts of the record industry committed to achieving a reduction in impacts from CD packaging, engaging their supply chain and artists in the process.
