Opportunity NOx: How to fix the IMO’s backwards air pollution regulation
New research by the ICCT reveals that ships with newer Tier II engines emit more nitrogen oxides (NOx) than ships with older Tier I engines, highlighting the need for stricter emissions standards and testing methods in the maritime sector.

Which automakers are keeping the ZEV momentum strong?
This blog discusses top automakers’ progress in setting zero-emission vehicle (ZEV) targets through September 2023, highlights notable commitments, and compares their ambition across different regions.

Under the hood: Some automakers are surprising in the EV race
In the high-stakes race away from conventional internal combustion engine vehicles and toward a zero-tailpipe-emissions future, the traditional hierarchies among light-duty vehicle (LDV) manufacturers are ripe for reshuffling.

IMO’s newly revised GHG strategy: What it means for shipping and the Paris Agreement
The 2023 strategy contains big improvements, including a net-zero date around 2050 and interim emissions reduction targets for 2030 and 2040.

Fair fares for the climate
Airlines already have the pricing strategies they need to help fund net-zero targets in an equitable way.

Would a frequent flying tax be progressive?
In September 2022, we published a proposal for using a global frequent flying levy (FFL) to cover the estimated abatement cost of commercial aviation. Now we investigate whether this solution is progressive or regressive.

Quick pit stops: A challenge for zero-emission planes?
Analyzes the charging and refueling speeds needed for zero-emission aircraft to match the gate turnaround times of conventional aircraft.

Beyond Europe: Are there ambitious electrification targets across major markets?
A recent string of voluntary electrification targets set by large car manufacturers could be the start of more ambitious global announcements in the future, if major vehicle markets other than Europe set regulations to drive accelerated adoption of zero-emission vehicles.

What to expect when expecting electric airplanes
Assesses the potential of battery-powered aircraft to replace regional, narrowbody, and widebody aircraft.

The tortoise and the hare? The race to decarbonize aviation
Explores whether aviation emissions can be greatly reduced if air traffic returns to its pre-pandemic rapid growth.

The G7 gets serious about decarbonizing road transportation
With everything else going on, you might have missed that the G7 ministers of climate, energy, and environment met in late May in Berlin and issued what is arguably the group’s strongest statement to date. The 39-page communiqué didn’t shy away from difficult questions. The ministers took strong stances on a range of topics bearing […]

Flying on the Grid
Argues that unless alternative aviation fuels are produced using additional and renewable electricity, their use will not necessarily decarbonize aviation and could actually increase aviation’s GHG emissions.
