Product Environmental Policy Stock and Impact Tool
overview
main purpose
summary
The Product Environmental Policy Stock and Impact Tool– PEPSIT is a quantitative tool developed to support EU environment and sustainability policies through socio-economic analyses of technology options of products and processes,at EU-level.
The tool has three main goals:
- To carry out techno-economic characterization of products
- To estimate the sales and stocks of given products over time, in the EU
- To perform quantitative environmental and economic impact assessments of different technology options
The tool is based on a bottom-up stock and cash flow model, that provides the quantitative information underpinning the impact assessments for product policies. It integrates calculations at the unit level (i.e. one unit of a product) such as the product lifetime, utilities consumption and cost breakdown, life cycle costing and life cycle impacts. This is extrapolated to EU-level using the stock and sales information, allowing the estimation of economic or environmental impacts at EU level.
The policy areas of potential use of the model are eco-design, energy label, ecolabel, green public procurement (GPP) extended product responsibility and product end of life policy. It has been successfully used in a number of EC impact assessments.

details on model structure and approach
- To start the modelling of a new product, one can start from scratch, introducing all parameters, or use default values. A dashboard intro sheet describes the main step of the model and the parameters and calculations to be used
- The main results are presented in an output sheet
model inputs
For each new product analysed, the Inputs are:
- Sales, or stock, or ownership ratio of the population of the product
- Lifetime of the product (stochastic or deterministic: average lifetime, Weibull parameters
- Information on End-of-Life (EoL) (percentage reused, recycled, disposed of)
- Sales distribution of different subtypes of the product
- Utilities consumption (energy, gas, water, etc) per subtypes of the product (e.g. energy efficiency class)
- Categorization of technologies (mature or emerging)
- Manufacturer production cost or the base case
- Increase pf the Manufacture Production Costs (MPC) per energy efficiency class
- Breakdown of the Manufacture Production Costs (MPC). Learning curve parameters
- Sales mark-ups
model outputs
The tool can calculate for each product one or more of the following outputs:
- Average product lifetime
- Average product utility consumption
- Sales and stock in the EU
- Life Cycle Costing (LCC) at unit level and at EU level :
- Installation costs
- Repair & maintenance
- Operation costs (auxiliaries)
- Operation costs (utilities (energy and water)
- Purchase price (ORP)
