Life Cycle Assessment

“The greatest threat to our planet is the belief that someone else will save it.” – Robert Swan

Introduction

In Hindu tradition, life is divided into four stages, known as the Ashramas. These stages are designed to provide a framework for living a meaningful and balanced life, addressing spiritual, personal, and societal responsibilities. The four stages are Brahmacharya (The Student Stage), Grihastha (The Householder Stage), Vanaprastha (The Hermit or Forest-Dweller Stage) and Sannyasa (renunciation).

These stages reflect a holistic approach to life, balancing personal growth, social responsibilities, and spiritual fulfilment.

Objective

Life Cycle Assessment (LCA) is a systematic method used to evaluate the environmental impacts of a product, process, or service throughout its entire life cycle. It is a vital tool for understanding and reducing environmental impacts.

Once you go through the article, you will understand, what is the meaning of Life Cycle Assessment (LCA), Why it is important, what is its purpose, what are the key challenges and how to interpret it.

Definition: ISO 59004: 2024

Circular Economy (Cl 3.1.1): Economic system that uses a systematic approach to maintain a circular flow of resources by recovering, retaining or adding to their value while contributing to sustainable development.

Sustainable Development (Cl 3.1.11): Development that meets the environmental, social economic needs of the present without compromising the ability of the future generations to meet their own needs.

Life Cycle (Cl 3.2.4): Consecutive and interlinked stages in the life of a solution.

Linear Economy (Cl 3.5.10): Economic system where resources typically follow the pattern of extraction, production, use and disposal.

End of Life (Cl 3.5.30): <Product> point in time when a product is taken out of use and its resources are either recovered for processing or disposed of.

Life Cycle Assessment (Cl 3.6.8): Compilation and evaluation of the inputs, outputs and potential environmental impacts of a product system throughout its life cycle.

Detailed Information

The global economy is “linear” as it is mainly based on extraction, production, use and disposal. This linear economy leads to resource depletion, biodiversity loss, waste and harmful losses and releases.

There is an increased understanding that a transition towards an economy that is more circular, based on a circular use of resources, can contribute to meeting current and future human needs (welfare, housing, nutrition, healthcare, mobility, etc.).

Sustainability is an essential part of facing current and future global challenges, not only those related to the environment. It’s a holistic approach that considers the social, environmental and economic impacts of actions and decisions taken today.

Life Cycle Assessment (LCA):

The term life cycle refers to the notion that a fair, holistic assessment requires the assessment of raw-material production, manufacture, distribution, use and disposal including all intervening transportation steps necessary or caused by the product’s existence.

The goal of LCA is to compare the full range of environmental effects assignable to products and services by quantifying all inputs and outputs of material flows and assessing how these material flows affect the environment. This information is used to improve processes, support policy and provide a sound basis for informed decisions.

Meaning of Cradle to Cradle (C2C)

“Cradle to Cradle” (C2C) is a sustainable design philosophy and framework that emphasizes the creation of products and systems where every material and resource is continuously reused in a closed-loop cycle. Unlike the traditional “cradle-to-grave” approach—where materials are ultimately discarded as waste—C2C envisions products that either return safely to nature or are perpetually recycled into new products without losing value or quality.

Purpose of LCA:

The purpose of Life Cycle Assessment (LCA) is to evaluate the environmental impacts of a product, process, or service throughout its entire lifecycle. It helps organizations, policymakers, and consumers make informed decisions that promote sustainability. The primary objectives include:

Reduce the impact of new products on the environment. Evaluating the benefits of switching from fossil fuels to renewable energy
Identifying what can be improved in the existing product. Assessing the impact of introducing biodegradable packaging.
Avoid an aspect of a product which can impact the environment more by encouraging Responsible Design and Manufacturing
Compare the environmental performance with similar products. Comparing the environmental impact of plastic vs. glass bottles.

LCA helps bridge the gap between environmental concerns and practical decision-making, paving the way for more sustainable development.

The Four Fundamental Steps of LCA

LCA is a standardized methodology, which makes it reliable and transparent. The International Organization for Standardization (ISO) provides standards for LCA in ISO 14040 and 14044. LCA is an iterative methodology, where you refine things as you go along. These standards describe the four main phases of an LCA:

Goal and Scope Definition: Determine the purpose of the study and what is being assessed. Specify system boundaries (e.g., cradle-to-gate, cradle-to-grave).

Inventory Analysis: Collect data on material inputs, energy consumption, emissions, and waste generation across all stages
Impact Assessment: Analyze the potential environmental impacts of the inventory data, such as global warming potential, water usage, and toxicity levels
Interpretation: Evaluate the results, identify improvement opportunities, and make recommendations

Challenges in Life Cycle Assessment

Despite its benefits, LCA poses several challenges:

Data Collection: Gathering accurate and comprehensive data across the supply chain can be difficult and time-consuming.
Complexity: The interconnected nature of processes makes it challenging to set system boundaries and avoid double-counting.
Resource Intensive: LCA requires technical expertise, software, and significant time investment.
Data Variability: Variations in regional or temporal factors can lead to inconsistent results.

Subjectivity: Decisions about system boundaries, allocation methods, and impact categories can influence the outcome.

Conclusion:

LCA is a complex and comprehensive tool used to measure and reduce the environmental impacts of products throughout their life cycle. Several different software programs and tools available can help with life cycle assessment. When using LCA, it is essential to employ accurate and consistent data collection.
