The importance of food supply chain emissions has increased. According to a study, entitled Food Systems Are Responsible for a Third of Global Anthropogenic GHG Emissions, recently published in Nature Food by Monica Crippa et al. (2021), our food systems emit 34% of the world’s greenhouse gas emissions every year. It turns out that “[t]he largest contribution came from agriculture and land use/land-use change activities (71%), with the remaining were from supply chain activities: retail, transport, consumption, fuel production, waste management, industrial processes and packaging”. What is remarkable about this study is the level of detail and size of the dataset, called EDGAR-FOOD, which identifies the sources of greenhouse gas emissions across the entire food production and supply chain. One of the coauthors argues that “[a]ny policy decision requires a good and robust evidence base”, hoping that “EDGAR-FOOD will be helpful in identifying where action to reduce food system greenhouse gas emissions is most effective”.

JSCM talked to me about my new paper, entitled Dancing the Supply Chain: Toward Transformative Supply Chain Management:
A new World Economic Forum report, entitled Net-Zero Challenge: The Supply Chain Opportunity and co-authored with Boston Consulting Group, showcases “the opportunity that all companies have for huge climate impact through action to decarbonize global supply chains”. This report argues that addressing supply-chain emissions enables many companies to impact “a volume of emissions several times higher than they could if they were to focus on decarbonizing their own direct operations and power consumption alone”. Among the major findings of the report: (1) Many companies can multiply their climate impact by decarbonizing supply chains; (2) Eight supply chains account for more than 50% of global emissions; (3) Net-zero supply chains would hardly increase end-consumer costs; (4) But: decarbonizing supply chains is hard. The report contains a step-by-step guide, which shows nine major initiatives every company can undertake. These initiatives were identified through interviews with a large number of global companies that, according to the authors, lead the way in reducing supply-chain emissions.
The IPCC defines the world’s remaining carbon budget as the cumulative net global anthropogenic CO2 emissions to the time that emissions reach net zero that would result in limiting global warming to a given level, accounting for the impact of other anthropogenic emissions. In other words, it allows us to calculate how much CO2 can still be released to limit global warming to a maximum of 1.5°C and 2°C, respectively. Currently, emissions equivalent to 42 gigatonnes (Gt) of CO2 are released globally every year. The following MCC Carbon Clock shows that time is ticking very fast and that we urgently would need to decarbonize our global supply chains.
The whole world can see it clearly. A wind of change is currently blowing through the air and the past eventful weeks have almost turned it into a storm: The IPCC published its Special Report on the Ocean and Cryosphere in a Changing Climate; world leaders at the Climate Action Summit in New York demonstrated growing recognition that the pace of climate action must be rapidly accelerated; climate activist Greta Thunberg received the Right Livelihood Award “for inspiring and amplifying political demands for urgent climate action reflecting scientific facts”; several million people across the globe joined the Global Climate Strike; Germany followed other countries by introducing a carbon price; and the European Investment Bank decided to divest from fossil fuel projects. It is becoming increasingly clear that the fossil era, which has long shaped the global power structure, is coming to an end. While late movers are now desperately trying to conserve the obsolete fossil solutions of the 20th century with the help of trade barriers, those states relying on green technologies are gaining significant influence. The task of our discipline is now to adapt our theories, methods and practices to this new reality. Exciting times are ahead!
In this TED-Ed video, Kim Preshoff investigates the smartphone production: “As of 2018, there are around 2.5 billion smartphone users in the world. If we broke open all the newest phones and split them into their component parts, that would produce around 85,000 kg of gold, 875,000 of silver, and 40,000,000 of copper.” I really like the video, as it takes a supply chain perspective, and I can imagine to use it in my future SCM courses.
