“Women use cars for time management”

… would probably sum up this article (Jain et al., in press). Here’s the twist: The caring aspect of women may lead to the choice of other transportation modes (notably more sustainable ones) otherwise but is outweighed by the question of time management related to the schooling of dependent children. In other words, if you run back and forth to school and the hobbies of your kids (who doesn’t cry out loud at people calling that “logistics”?), you stop caring about the environment. Quite an issue to take into account from a sustainable behaviour perspective. I wonder how personal carbon emission budgets would affect this though.

PS. Loved the interesting method of the article though.

Cutting transportation emissions the radical way

Once again there are some radical suggestions to cut transportation emissions on the climate change agenda: now the EU suggests to ban cars from cities by 2050 and to cut budget flights as to encourage a modal choice back to rail. Earlier on it was Norway discussing an end to petrol-driven cars by 2015 already.

Radical? Think again. These efforts come years after setting similar targets in construction which are in the spotlight again due to recent events related to nuclear power and the effect of these events on the political arena. So perhaps it is time to prepare for big changes in transportation as well.

Old hat, new hat: energy efficiency

We are still talking about energy efficiency (and carbon efficiency) while other industries have gone much further and introduced plus-energy initiatives. Plus-energy housing, for instance, goes beyond the idea of self-sufficiency of the passive house and energy efficient house (here’s a comparison). But who says this is only an initiative in architecture? Solar power plants can also be used for fork lifts, even in areas where sunshine is not given all year round (and solar panels could potentially be covered by snow), ventilation systems can recover the energy they used, entire farms can work on a plus-energy principle, etc. Whilst these initiatives are mainly location-bound and focus on products that (arguably) use most energy during their usage period, the concept is still to be employed in the supply chain. As is the concept of water harvesting and preservation – the water footprint of the supply chain. There is always room for improvement.

Carbon footprints & the sourcing decision: make-buy-or-sell

The EU ETS (Emission Trading Scheme) will most likely have implications for design and operation of supply networks.

One of the emerging questions is whether (or perhaps rather, to what extent) allocation of carbon emission credits to companies will reduce carbon footprint of the particular product.

Let’s for the sake of the argument view the physical product and the individual company as unit of analysis.

There are at least two aspects that are of interest for those who work with the term ‘supply chain’ in their research and management practice:

1. Pushing emission up-stream the supply chain?
A problem may arise if these are not distinguished properly, for example if a company seeks to reduce it’s carbon emission by pushing emission-intensive operations up-stream their supply chains, into the hands of their suppliers.

One of the criticism of just-in-time and lean operations was the idea of inventories being pushed up-stream the supply chain, into the hands of the suppliers. As consequence, the stock of particular components was not reduced, it was simply re-located.

Will this also happen with carbon emission?

2. Make-buy-or-sell.

For a company that is efficiently managing it’s carbon footprint, and under circumstances t where demand of carbon credits exceeds supply, will the sourcing criteria now include sell? That is, either selling credits to suppliers and customers who are in need of this, or even taking over some operations from these supply chain members that are carbon intenstive?

This is of course highly speculative, but nevertheless, with an efficient market for carbon credits, the sourcing criteria will certainly extent to: make-buy-or-sell.

Commute greener or run to work

Green office initiatives have embraced the idea of reducing one’s transportation emissions on the way to work for a while, now Volvo (yes, the car company that was just sold to Geely) came out with a “commute greener” technology that should make people (including car drivers) aware of the carbon emissions they create by commuting. The newest trend, though, surpasses it all, “transportlöpning” a.k.a. run to your work and get fit at the same time. On your marks, get set, go!

Green and healthy supply chains

Trendspotting on our CFP wall points again at two current focal themes of research, “green supply chain management” and “health care supply chains”. Here’s a more focused assembly of the CFPs.

Green supply chain management: Mar 31 is the deadline of two calls for papers on this topic (sustainability with a call on “Supply chain sustainability“ and Transportation Research Part E on “Green supply chain management“). It then follows with a CFP for the African Journal of Economic and Management Studies on “CSR in Africa“ (Jun 30), and another for the Journal of Cleaner Production on “Sustainability management beyond corporate boundaries“ (Aug 31). The International Journal of Production Economics has two at almost the same time, “Green manufacturing and distribution in the fashion and apparel industries“ (Sep 30) and “Sustainable development of manufacturing and services“ (Oct 30). Timely enough, the International Journal of Physical Distribution and Logistics Management dedicated its first two numbers of 2010 to sustainability in supply chains. Now even marketing journals are waking up for the topic, see e.g. the Journal of Marketing Management CFP on “Re-visiting contemporary issues in green/ethical marketing” (due in a year, Mar 1, 2011).

Health care operations and SCM: Apr 6 is the first deadline to note here, with a CFP for the European Journal of Operational Research on “Operations research in health care“. One can also note the Annals of Operations Research calls for papers on “OR in the public sector and NPO“ (Apr 30), OR Spectrum’s CFP on “Healthcare operations management“ (Jun 30), as well as CFPs for Decision Support Systems on “Modeling for better healthcare“ (Sep 15), Computers and Operations Research on “Operations research for health care delivery“ (Dec 2010). It is mostly OR and OM research that is called for in health care right now.

Radical change for green logistics

How do you induce radical change in green logistics? The discussion easily drifts into one of policy, taxes and transport, but what are the effects on systems and supply chains? Green logistics may require a redefinition of delivery service requirements based on the idea of reducing inventory costs and rather, introduce longer lead times etc. The question is not only whether industry is up for it, but is academia ready to go down that road? An award goes to the first SCM textbook that embraces this idea and implements it through all concepts and chapters – the new Green Logistics book perhaps :-)

Visualising carbon footprints in the supply chain

Whilst the academic debate on how to calculate carbon footprints is a never-ending story and companies are still struggling to see where to reduce their CO2 emissions, there are at least some tools that help visualising the basic idea. Here’s the recipe: Take a product (or a food item), add its parts and raw materials, the location of these, the energy used to produce them, the transportation mode etc. and draw a map of your CO2 emissions. You can change each of the parameters (i.e. what if you suddenly produced a part with say, wind power instead of the general electric grid or what if the location of a supplier was different) and play with the results. You can even browse the maps of others. My favourites are a homemade bacon omelette and the typical laptop computer. What is yours?

Now: LRN 2009

Here we are at the Logistics Research Network conference in Cardiff. This year’s presentations were of outstanding quality. Not surprisingly there was a big green logistics track, with anything from green SCM capabilities to CO2 emissions in cities to transportation emissions represented. Other interesting (or let’s say, unusual ones) were on food supply chains and logistics education. Humanitarian logistics figured again.

A novelty at this conference was a “best poster” award. What a great idea! People had been put down about not getting into the proceedings and “just” presenting a poster. Funny that poster sessions in say, health care, or engineering, are seen as really positive, while at logistics conferences they are less appreciated. But posters have their own place at a conference, for research in its early phase, as well as to find collaborators for new projects. So why don’t SCM academics want to present posters at a conference?

Supply chain design for carbon trading

Supply chain design for carbon trading

–Perhaps a speculative statement, but not for long.

As companies can buy emission credits on auctions and marketplaces (horisontal structure of carbon trading), why not include them in trading with suppliers and customers (vertical structure of carbon trading)?

More thoughts on this very soon.
