Devil in the detail of Europe’s 2050 transport model

As the EU puts together a mid-century climate strategy, Carlos Calvo Ambel explains how the Commission’s choice of modelling could be severely underestimating what emission cuts can be gained from the transport sector.

Aviation biofuels: Won’t get fooled again

Biofuels are being touted as a solution to the problem of aviation emissions. But previous experience shows us we must take care to ensure they are not actually worse for the environment than the kerosene they replace, writes Carlos Calvo Ambel.

When it comes to cutting Europe’s CO2, trucks drive under the radar

Heavy duty vehicles account for a significant portion of CO2 emissions, and their impact is only supposed to increase. New measures must be adopted quickly in order to achieve climate goals, writes Carlos Calvo Ambel.

Biomass’ ‘zero’ ETS rating burns us all

We have no idea if the biomass burned actually reduces CO2 emissions, which raises questions about the energy source's zero rating in the EU's Emissions Trading System, writes Carlos Calvo Ambel.

A shock to the system: Why energy union must deliver transport efficiency and electrification

The global picture is clear: both demand for surface transport and resulting CO2 emissions are going to skyrocket by 2050. Even for those who analyse transport on a daily basis the figures are startling – an increase of up to 110% in carbon emissions from passenger transport and up to a whopping 600% from freight, says transport expert.
