The 2015 Paris Agreement aims to limit global-mean temperature rise to 1.5 °C. This study explores scenarios that can achieve this target by limiting end-of-century radiative forcing to 1.9 W m⁻², with a median warming in 2100 below 1.5 °C. Six integrated assessment models and a simple climate model are used under five Shared Socio-economic Pathways (SSPs). Some SSPs are more amenable to achieving the 1.9 W m⁻² target, which requires rapid shifts away from fossil fuels, reduced energy use, and carbon dioxide removal. However, this target is challenging under SSPs with strong inequalities, high baseline fossil-fuel use, or scattered short-term climate policies. The scenarios inform policy by highlighting the importance of demand-side mitigation, energy efficiency, and comprehensive emission reductions. The study also discusses the feasibility of these scenarios, noting that while they provide insights, real-world feasibility depends on factors not fully captured by models, such as social support and technological advancements.The 2015 Paris Agreement aims to limit global-mean temperature rise to 1.5 °C.
