Meeting the Paris Agreement's goal to limit global warming to well below 2 degrees C and pursuing efforts towards 1.5 degrees C is likely to require more rapid and fundamental energy system changes than the previously-agreed 2 degrees C target. Here we assess over 200 integrated assessment model scenarios which achieve 2 degrees C and well-below 2 degrees C targets, drawn from the IPCC's fifth assessment report database combined with a set of 1.5 degrees C scenarios produced in recent years. We specifically assess differences in a range of near-term indicators describing CO2 emissions reductions pathways, changes in primary energy and final energy across the economy's major sectors, in addition to more detailed metrics around the use of carbon capture and storage (CCS), negative emissions, low-carbon electricity and hydrogen.
