The proposed Sustainable Highlands Highway Infrastructure Program (SHHIP) is envisaged as a ten- year, multi-partner, multi-tranche financing facility aiming to restore and upgrade the Highlands Highway in Papua New Guinea (PNG). The executing agency is the PNG Department of Works (DoW). The initial climate screening of SHHIP using AWARE determined the Investment Program to be at medium risk to climate and climate change. As a result, ADB procedures require that a climate risk and vulnerability assessment (CRVA) be undertaken during the design stage.
This report synthesizes the emerging evidence of climate impacts at different temperature thresholds for Pacific islands. All evidence points to vast differences in impacts in a 1.5˚C world, compared to the +3˚C world to which our current policies and climate change pledges are leading us. For Pacific islands and marine and coastal ecosystems in the region, these differences cannot be overstated; even a 0.5˚C difference (between 1.5˚C and 2˚C) may mean that critical tipping points are crossed.
