\"BuildGreen Construction,\" a company specializing in sustainable building materials, is evaluating the environmental impact of using cross-laminated timber (CLT) in a new high-rise project compared to traditional concrete construction. They aim to conduct a Life Cycle Assessment (LCA) according to ISO 14044 to inform their material selection decision. Ms. Priya Patel, the project manager, is responsible for defining the system boundaries for the LCA. Which of the following considerations is MOST critical for Ms. Patel to ensure that the system boundaries are comprehensive and relevant to the decision-making process?
Limiting the system boundaries to only include the manufacturing and transportation stages of the CLT and concrete, excluding the extraction of raw materials, construction processes, and end-of-life scenarios.
Including all relevant stages of the life cycle, from raw material extraction and processing, manufacturing, transportation, construction, use phase (including energy consumption for heating and cooling), and end-of-life scenarios (including demolition, recycling, and disposal), while justifying any exclusions based on their significance and relevance to the study's goal.
Focusing solely on the carbon footprint of the CLT and concrete, without considering other environmental impact categories such as water use, air pollution, and resource depletion.
Defining the system boundaries based solely on data availability and cost considerations, without regard to the potential environmental impacts or the relevance to the decision-making process.
