Inventory of carbon and energy (ICE)

This category is deprecated


The 'boundaries' represented by each embodied CO2 factor are described in AMEE as follows;

  • "Cradle to grave" - embodied CO2 from entire life cycle of material
  • "Cradle to gate" - embodied CO2 from resource extraction to factory gate
  • "Cradle to site" - embodied CO2 from resource extraction to final point of use (e.g. building site)

For reinforced concrete, see this related methodology.

How to use this category

Selecting an emissions scenario

To use this category, use drill-downs to specify the material, type and subtype.

Specifying activity data

Next, enter the quantity used using the mass profile item.

Results and calculation

The quantities returned represent embodied energy and CO2 emissions associated with the quantity specified. The following quantities are returned:

  • energy: embodied energy, in Megajoules
  • CO2: embodied CO2


Data ranges

Several embodied CO2 factors presented in ICE are specified as a range of values. In such cases, AMEE provides the option of choosing minimum or maximum values.

Insulation plastics

Data for polystyrene- and polyethylene-based insulation materials are referenced from the 'plastics' category in ICE.

Derived CO2 factors

ICE contains many materials for which only embodied energy is specified. Only materials which include either (a) an explicit embodied CO2 factor, or (b) an embodied energy factor plus the associated energy fuel split (from which embodied CO2 can be derived) are included within AMEE. The latter method was used to derive embodied CO2 factors for clay/limestone bricks and wood-wool reinforced concrete.
