Comparing Sectors at CAIT

[zoa-energ...@basf.com]

Dear Sir or Madam,

a short question to your superb CAIT-System. When comparing the emissions resulting from different sectors, these include "Energy" and "Industrial Processes". The sector "Energy" is devided again into different sectors, one of them the "Manufactoring & Contruction"-sector. Having a look at the US and/or EU emissions resulting from those sectors shows me, that the emissions resulting from industrial processes are surprisingly low (3.6 and 5.2). This might as well result from the emissions stated at "Manufactoring & Construction", which could as well be stated as "industrial processes". My question is, how you define "Industrial Processes" and "Manufactoring & Construction".

Thank you so much!

Jan,

You can find a detailed methodology paper at http://cait.wri.org/downloads/cait_ghgs.pdf

In section 5, 'Sector-Level GHG Emissions Data', you will find a table
of how sources are categorized.

I'll include the more detailed methodology description for your
convenience:

"The CAIT sub-sector Manufacturing/Construction, drawn from IEA
(2007), includes CO2 emission
from fossil fuel combustion in the following activities:
- Iron and Steel
- Chemicals and Petrochemicals
- Non-Ferrous Metals
- Non-Metallic Minerals
- Transport Equipment
- Machinery
- Mining and Quarrying
- Food and Tobacco
- Paper, Pulp and Printing
- Wood and Wood Products
- Construction
- Textile and Leather
- Non-specified Industry
- Non-Energy Use Ind/Transf/Energy

In CAIT, emissions from the above activities are summed into a single
yearly estimate for
Manufacturing/Construction. See IEA (2007) for specific emission
estimates for each of the
activities listed above (including disaggregated by fuel sources).

Manufacturing/Construction corresponds to the IPCC Source/Sink
Category 1 A 2. However, the
IEA (2007) notes that in the IPCC Guidelines (IPCC, 1996b), IPCC
Category 1 A 2 also
includes emissions from industry autoproducers that generate
electricity and/or heat. These
emissions are not included here. Because of IEA’s data collection
methods, emissions from
autoproducers are shown as a separate item (“Unallocated
Autoproducers”). The IEA (2007)
also notes that Manufacturing Industries and Construction includes
emissions from coke inputs
into blast furnaces, which may be reported either in the
transformation sector, the industry
sector or the separate IPCC Source/Sink Category 2, Industrial
Processes."

For Industrial Processes:

"The CAIT Industrial Processes sector includes:
- CO2 emissions from Cement Manufacture (CDIAC; Marland et al., 2008)
- N2O emissions from Adipic and Nitric Acid Production (EPA, 2006)
- N2O and CH4 emissions from Other Industrial (non-agriculture) (EPA,
2006)
- HFCs, PFCs, and SF6 (EPA, 2004; 2006)

CO2 emissions from Cement Manufacture, drawn from CDIAC (Marland et
al., 2008), is described
in Section 2.2. N2O emission from Adipic and Nitric Acid Production
are drawn from EPA (2006).
Emission estimates of high global warming potential (GWP) gases,
namely HFCs, PFCs, and SF6,
are drawn from EPA (2004; 2006).

This sector is compiled so as to best match IPCC Source/Sink Category
2 (Industrial Processes).
However, IPCC Guidelines (1996b) include several subsectors under
Industrial Processes that, due
to lack of data, are not included in CAIT. These include emissions
from, inter alia, the chemical
industry and iron and steel production. In CAIT, as noted above, some
of these emissions may
instead be included in the Energy sector under Manufacturing and
Construction."

Hope this answers your question.

Best,
Jack
