Key terms
Life Cycle Assessment
A systematic process for evaluating the environmental impacts associated with all stages of a product's life, from raw material extraction through to disposal.
Environmental Impact
The effect that a product or process has on the environment, which can include resource use, energy consumption, and waste generation.
Life Cycle Assessment
A systematic analysis of the environmental impacts associated with all stages of a product's life, from raw material extraction to disposal.
Raw Materials
The basic materials from which products are made, which are extracted and processed during the life cycle assessment.
life cycle assessment
A method for assessing environmental impacts over the stages in a product's life.
manufacturing
The process of converting raw materials into finished products, a key stage in life cycle assessment.
life cycle assessment
A method for assessing environmental impacts over the stages in a product's life.
use stage
In Life cycle assessment, use stage means the phase in a product's life cycle where it is actively used and operated by consumers. This matters in Life cycle assessment and recycling because it supports the learning objective to describe use and operation during a product's lifetime as a stage in life cycle assessment. Use use stage only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
disposal
In Life cycle assessment, disposal means the stage in life cycle assessment where products are discarded or disposed of after use. This matters in Life cycle assessment and recycling because it supports the learning objective to describe disposal, transport and distribution as stages in life cycle assessment. Use disposal only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
transport
The stage in life cycle assessment involving the movement of products from one location to another.
Life Cycle Assessment (LCA)
A systematic analysis of the environmental impacts of a product throughout its life stages.
Resource Use
The consumption of natural resources during the extraction, processing, and disposal stages of a product's life.
value judgement
A subjective assessment that reflects personal beliefs or opinions when assigning numerical values to the effects of pollutants.
pollutant effects
The environmental impacts caused by substances that contaminate air, water, or soil, which can be quantified in life cycle assessments.
life cycle assessment
A systematic analysis of the environmental impacts of a product throughout its life stages.
value judgement
An assessment that involves personal beliefs or opinions, which can affect the objectivity of life cycle assessments.
Selective LCA
A life cycle assessment that focuses on specific stages or impacts, potentially omitting important data.
Abbreviated LCA
A shortened life cycle assessment that may not provide a comprehensive view of environmental impacts.
Life Cycle Assessment (LCA)
A systematic analysis of the environmental impacts of a product throughout its life stages, from raw material extraction to disposal.
Comparative LCA
An evaluation that compares the environmental impacts of different products or processes, such as plastic and paper shopping bags.
Life Cycle Assessment
A systematic analysis of the environmental impacts of a product throughout its life stages.
Environmental Impact
The effect that a product's life cycle has on the environment, including resource use and waste generation.
Life Cycle Assessment (LCA)
A systematic analysis of the environmental impacts of a product throughout its life stages.
Significant Figures
In Life cycle assessment, Significant Figures means digits in a number that carry meaningful information about its precision. This matters in Life cycle assessment and recycling because it supports the learning objective to use decimals, ratios, fractions, percentages, estimates and suitable significant figures when interpreting LCA data. (MS 1a, 1c, 1d, 2a). Use Significant Figures only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
Life Cycle Assessment (LCA)
A systematic analysis of the environmental impacts of a product throughout its life stages.
Graphical Representation
A visual format for displaying data, such as charts or graphs, used to interpret life cycle assessment information.
reducing use
In Ways of reducing the use of resources, reducing use means the practice of minimizing the consumption of resources to conserve limited supplies. This matters in Life cycle assessment and recycling because it supports the learning objective to explain how reducing use, reusing products and recycling materials can reduce limited resource use. Use reducing use only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
recycling materials
The process of converting waste materials into new products to reduce resource use and environmental impact.
reducing use
In Ways of reducing the use of resources, reducing use means the practice of minimizing consumption of resources to decrease environmental impact. This matters in Life cycle assessment and recycling because it supports the learning objective to explain how reducing use, reusing products and recycling materials can reduce energy use, waste and environmental impact. Use reducing use only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
recycling materials
The process of converting waste materials into new products to reduce resource use and environmental harm.
