Representative Concentration Pathways (RCPs) are scenarios used in climate science to project the possible future concentrations of greenhouse gases and their associated radiative forcing, which directly affects global temperature rise. Although primarily applied in climate modeling, their relevance to the construction industry arises because the sector significantly contributes to greenhouse gas emissions through the use of energy-intensive materials like cement, steel, and fossil-fuel-powered machinery. Understanding RCPs allows construction planners and safety managers to anticipate environmental changes, such as extreme weather events, temperature fluctuations, and sea-level rise, that can impact construction site safety and worker well-being. The RCP framework is composed of four main pathways, identified by the level of radiative forcing they are likely to achieve by the year 2100. These pathways are RCP2.6, RCP4.5, RCP6.0, and RCP8.5, with values representing the additional watts per square meter of energy absorbed by the Earth due to greenhouse gases. RCP2.6 represents an aggressive mitigation scenario with peak emissions around 2020 and a subsequent decline, aiming to limit global temperature rise to below 2°C. RCP4.5 and RCP6.0 represent stabilization scenarios with moderate emissions reductions, while RCP8.5 represents a high-emission, “business as usual” scenario where greenhouse gas emissions continue to increase. Each pathway reflects different assumptions about economic growth, energy production, technological advancement, and policy interventions, which indirectly affect construction practices and safety standards. In the context of the construction industry, the selection
