We review the scientific literature on evidence which policies can deliver deep CO2 mitigation
A huge reduction in road transport CO2 emissions is required to fulfill transport's part of the Paris agreement
Key conclusions: 1. A single policy alone is probably not sufficient. 2. A balanced mix of low carbon fuel standards, zero emission vehicle mandates and CO2 fleet targets seems the best way forward.

Quite important for the economics discussion: we see little evidence that pricing alone can lead to deep greenhouses gas mitigation.

What is the future role of #hydrogen in road transport?
In a new comment in @NatureElectron I argue, that hydrogen is unlikely to play a major
role in sustainable road transport.
A thread on the arguments [1/n]
1. Cars: Almost all car manufacturers gave up on fuel cell passenger cars as fast charging and cheap batteries make long-distance driving feasible with battery electric vehicles.
2. Road freight is more tricky: Depending on load and daily or annual driving distance, current battery electric trucks cannot cover all road freight transport needs.
Kernergebnisse:
– Ordnungsrecht kann aufgrund der hohen Wirksamkeit und politischen Akzeptanz eine führende Rolle spielen.
– Quoten für emissionsfreie Fahrzeuge, Quoten für CO2-arme Kraftstoffe und CO2-Flottengrenzwerte bieten großes CO2-Minderungspotenzial.
- Quoten für CO2-arme Kraftstoffe senden ein transformatives
Signal, auf alternative Kraftstoffe umzusteigen und senken die Gesamtemissionen für Personen- und Güterverkehr.
– Zweitens beschleunigt eine Quote für Nullemissionsfahrzeuge die Verbreitung von E-Fahrzeugen .
