Urban infrastructure choices structure climate solutions


Cities are becoming increasingly important in combatting climate change, but their overall role in global solution pathways remains unclear. Here we suggest structuring urban climate solutions along the use of existing and newly built infrastructures, providing estimates of the mitigation potential.

Persistent growth of carbon emissions

Two thirds of the CO2 emission quota consistent with a 2°C temperature limit has already been used, and the total quota will likely be exhausted in a further 30 years at the 2014 emissions rates.Learnámore ╗

Betting on Negative Emissions

Bioenergy with carbon capture and storage could be used to remove carbon dioxide from the atmosphere. However, its credibility as a climate change mitigation option is unproven and its widespread deployment in climate stabilization scenarios might become a dangerous distraction.Learnámore ╗

Staying below 2°C

Global emissions are tracking the most pessimistic scenarios used by the IPCC. Glen Peters and colleagues present a comparison of emissions with all four sets of scenarios used by the IPCC since 1990, and argue that inertia in both human systems and the climate system make a 2°C goal harder with every day of inaction.Learnámore ╗
