OpenLCA is an open source software used for performing life cycle assessments and sustainability analyses. It allows users to create databases of flows (i.e. raw materials, inputs, and outputs), model processes showing material and emission inputs and outputs, build product system models by connecting flows and processes, and manage LCA projects in four main stages - flows, processes, product system, and project.

1. OpenLCA

2.  openLCA is an open source software for Life Cycle Assessment (LCA) and
sustainability assessment.
1. Life Cycle Assessment***
2. Life Cycle Costing (LCC)
3. Social Life Cycle Assessment (S-LCA)

3. openLCA - software has mainly four
stages
1. flows
2. Processes
3. Product system
4. project

4. flows
 Flows are base of any project in Open Lca (software).
 flows is collection of raw materials for various manufacturing plants or industry.
 In Open Lca(software) we can create our own database or we can extract from
other database like simapro, gabi softwares

5. processes
In this processes phase we use to add the INPUT and OUTPUTS from flows
INPUTS :
inputs are mainly raw materials for manufacturing plants or industry’s
OUTPUT:
Outputs are mainly emissions from extraction to demolition of any product
In this processes phase we can give geography information of particular location.

6. Product system
 In this product system phase we can create the model graph of any manufacturing
unit or industry.
 Product system is a mix of flows and process
