Hi David,

In a complicated situation with long supply chains, perhaps step-by-step English explanations of calculated results are useful?

As mentioned previously on this thread, there's a browser-based executable English way to do this.

It's online at the site below, with examples you can view, run and change, such as

Apologies if you have seen this before, and thanks for comments.

Dear All,

I agree with Duane's comments. The calculation of embedded CO2 is very
complicated, and the ontology/semantic web community has a key part of the
solution.

The problem is that the supply chains for most products are very long. For
example the CO2 calculations for an electronic product have to include the
mineral extraction to make the special steels, to make the machine tools, to
grind the glass in the optical instruments, which make the masks, etc.. For
this reason a standard in this area, BSI PAS 2050, excludes capital goods
from embedded CO2 calculations. So the calculation of the embedded CO2 in a
holiday includes the jet fuel burned during the flight, but not the fuel
needed to make the aeroplane.

The reason for the difficulty is simple - a manufacturer or supplier knows
about direct inputs, and direct outputs to waste disposal and re-cycling,
but nothing about what happens further up the supply chain, or further down
the disposal/re-cyclying chain. As a result, it would cost a
manufacturer/supplier a lot of time and money to produce an accurate
estimate of the embedded CO2 in a product.

A possible solution involves publication of information about inputs and
outputs by each organization within a supply chain (including the
disposal/re-cycling chain). Each organization would publish only what it
knows - direct inputs and outputs. The CO2 emissions embedded within a
product are then produced by software which navigates the published
information about the supply chain as a whole.

In order to enable this to happen, standard ontologies are needed:
- to represent product structure;
- to represent the inputs and outputs from processes.

There is another problem - security. The details of product structure, the
inputs and outputs from processes, and the organizations from which supplies
are obtained, are absolutely commercially confidential. The resulting
assessment of embedded CO2 may be commercially embarrasing, but is not
confidential in the same way. Hence there are two parts to implementing a
solution:
- standards ontologies which can describe a supply chain; and
- a network of non-disclosure agreements with environmental auditors which
will allow their software to navigate supply chain information published on
the Web to produce accurate figures for embedded CO2.

Such a network would not involve everybody, and so there would have to be
C02 estimates for non-participating organizations. The estimates could be
provided by data bases such as the EU Platform on LCA
<http://lct.jrc.ec.europa.eu/eplca>. If these estimates were sufficiently
conservative, then there would be an incentive to join the network.

Best regards,
David
