Why Conducting a LCA benefits your company and the environment

In recent years, there has been a growing interest in sustainable and environmentally responsible practices among consumers, governments, and corporations. One key aspect of sustainability is the life cycle analysis (LCA) of products, which assesses the environmental impact of a product throughout its entire life cycle. In this article, we'll explore why conducting an LCA is beneficial for companies, the environment, and society as a whole.

What is a Life Cycle Analysis?

A life cycle analysis is a tool used to assess the environmental impact of a product throughout its entire life cycle, from raw material extraction to disposal. This analysis takes into account all stages of a product's life, including production, distribution, use, and disposal. The goal of an LCA is to identify opportunities for reducing a product's environmental impact and improving its overall sustainability.

Not all LCAs are equal: The Different Types of Life Cycle Analyses

Scope:

The scope of an LCA refers to the boundaries of the analysis and what stages of the product's life cycle are included. Cradle-to-grave LCA has the broadest scope, while gate-to-gate LCA has a narrower scope.

Level of Detail:

The level of detail in an LCA refers to the amount of information and data that is collected and analyzed. Cradle-to-grave LCA requires the most data and is the most detailed, while gate-to-gate LCA is less detailed.

Comparability:

Different types of LCAs can be used to compare the environmental impact of different products or stages of production. Cradle-to-grave LCA provides the most comprehensive comparison, while gate-to-gate LCA provides a more specific comparison.

Different Types of Life Cycle Analyses

We will talk about different concepts of the product life cycle in just a moment, but generally, the product life cycle consists of five phases:

The 5 Steps of a Product Life Cycle (Cradle to Grave)

1. Raw Material Extraction
2. Manufacturing & Processing
3. Transportation
4. Usage & Retail
5. Waste Disposal

Different Life cycle models

Based on the stages you’re interested in or have data available on, you can choose to leave in or take out phases. There are usually 4 product life cycle models you can choose for your LCA.

1. Cradle-to-Grave LCA:

A cradle-to-grave LCA assesses the environmental impact of a product from the extraction of raw materials to the end of its useful life and disposal. This type of LCA is the most comprehensive and provides a complete picture of a product's environmental impact throughout its life cycle.

2. Cradle-to-Gate LCA:

A cradle-to-gate LCA assesses the environmental impact of a product from the extraction of raw materials to the point where the product leaves the factory gate. This type of LCA is useful for comparing the environmental impact of different products at the point of production.

3. Gate-to-Gate LCA:‍

A gate-to-gate LCA assesses the environmental impact of a product from the point where it enters the factory gate to the point where it leaves. This type of LCA is useful for assessing the environmental impact of a particular stage of production, such as manufacturing.
