CAP'EM INDIVIDUAL IMPACTS come out of LCA Life Cycle Analysis and are used for two important activities:

CAP'EM MARGINAL ANALYSIS to understand the relative impact of all the individual ingredients or parts e.g. products, packaging, inputs, outputs, plastics, chemicals,

CAP'EM INDIVIDUAL IMPACTS Calculation and disclosure of individual impacts used in literature and calculations e.g. Embodied Carbon, Global Warming Potential, Sequestered Carbon

CAP'EM PRODUCT IMPROVEMENT Using Marginal Analysis NGS assist the manufacturer to improve the product by minimising quntities of high impact ingredients or packaging and replaceing them with lower impact materials or energy sources.

CAP'EM DETOX uses a number of existing databases with detailed information on individual materials and chemicals to identify the worst offenders and identify other materials to consider for their replacements.

The manufacturer must then experiment with the alternatives to find the optimum performance with lower impacts.

This process can help in the REACH regulation drive to remove unhealthy chemicals from manufacturing.


LCA are based on hard and fast facts based on actual quantities reciep percentages and known material impacts, usually from 'cradle' (excavation from earth, extraction from plantations, etc.) to factory gate after manufacture.

EPD add onto the LCA from Factory Gate to Grave (including: construction, in use phase and end of life, landfill, recovery of energy (combustion) or nutrients (composting)) all of which is outside the realms of facts since they all occur in the future and based on current normal or best practice and some speculation.


GreenSpec use PASS to screen out the materials that have the highest environmental impacts and more importantly to identify the materials that have least impact and have a substantial contribution to make in use.  

GreenSpecPASS is used to select the Products that are then promoted in GreenSpecPRODUCT PAGES

Results of CAP'EM LCA and CAP'EM EPD can be recorded in NGS PRODUCT DATA SHEET schedules and NGS ROBUST SPECIFICATION clauses.

All of these results can be recorded in BIM-ready NGS CAD files promoted from GreenSpecPRODUCT PAGES
