==Overview==
Life Cycle Assessment (LCA) is a systematic methodology used to evaluate the environmental impacts associated with all the stages of a product's life, from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. LCA provides a comprehensive view of the environmental aspects and potential impacts of a product or service.


LCA is an integral part of sustainable product development and management, enabling businesses and organizations to understand and quantify the ecological footprint of their products throughout their entire life cycle. This includes everything from raw material extraction, manufacturing, and use, to disposal or recycling. In this article, we will delve into various LCA Indicators, each representing a different aspect of environmental impact. Understanding these indicators is key to making informed, eco-conscious decisions in product design and development. Let's explore these indicators and their significance in driving sustainable practices.
Objectives of LCA:
* '''Identify Improvement Opportunities''': Pinpoint areas within the product life cycle where environmental impacts can be reduced.
* '''Support Decision Making:''' Inform policymakers and industry leaders in making more environmentally conscious decisions.
* '''Enhance Product Design:''' Aid in the development of more sustainable products by understanding their environmental footprints.

Overview

Life Cycle Assessment (LCA) is a systematic methodology used to evaluate the environmental impacts associated with all the stages of a product's life, from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. LCA provides a comprehensive view of the environmental aspects and potential impacts of a product or service.

Objectives of LCA:

  • Identify Improvement Opportunities: Pinpoint areas within the product life cycle where environmental impacts can be reduced.
  • Support Decision Making: Inform policymakers and industry leaders in making more environmentally conscious decisions.
  • Enhance Product Design: Aid in the development of more sustainable products by understanding their environmental footprints.
