Policies to entice consumers away from fossil-fuel powered vehicles and normalize low carbon, alternative-fuel alternatives, such as electric vehicles, are vital if the world is to significantly reduce transport sector carbon pure-emissions, according to a new study. Note the different scaling used in the graphs. McCollum et al.

If a cap-and-trade program includes offsets, regulated entities have the opportunity to purchase the “emission credits” generated by carbon offset projects to help them meet their compliance obligations. This objective presents challenges because many offsets are difficult to measure. Emission reductions from regulated sources (e.g.,

The foundational idea is that the sun-obscuring aerosols fossil fuel consumption puts into the atmosphere would clear relatively quickly, but long-lived greenhouse gases such as carbon dioxide would persist and create a net warming. Climate change mitigation does not come at the expense of air pollution reductions.
