Supersonic aircraft: Twice as nice, or double the trouble?
Startups aiming to develop supersonic aircraft see a bright future, despite the high carbon intensity of their designs. But given evidence that supersonic aircraft will burn seven times more fuel per seat than subsonic aircraft, is there really room for supersonics in a net-zero future?
Maharashtra’s potential to advance transport decarbonization and clean air through low-emission zones
Maharashtra is among the pioneers of low-emission zones (LEZs) in India as its Electric Vehicle Policy, introduced in 2021, tasked six urban agglomerations with creating LEZs.
How U.S. ports can partner with the ICCT to leverage federal funding for electrification
With technical assistance from the ICCT, ports can conduct inventories of emissions and estimate the benefits of electrification.
Aligning the IMO’s Greenhouse Gas Fuel Standard with its GHG strategy and the Paris Agreement
Explores how the GHG Fuel Standard (GFS) can be designed to align with the International Maritime Organization’s (IMO) GHG strategy and the Paris Agreement.
Germany, not the land of compact cars: Why the EU new car CO2 standards are nothing to fear
Despite warnings that each step of the EU CO2 regulation would be too difficult to achieve, the targets have proven to be effective at driving innovation
Grounded (by beef)! A different take on aviation carbon accounting
The carbon footprint of eating meat is large. But it doesn’t compare to the footprint of frequent flying, which can be truly gargantuan.
No time to lose for the European Commission to make plug-in hybrid CO2 emission values more realistic — and no need to wait!
Assumptions regarding how frequently PHEVs are charged has a big impact on the gap between real-world and type-approval emissions.
Zero-emission shipping and the Paris Agreement: Why the IMO needs to pick a zero date and set interim targets in its revised GHG strategy
To align with the Paris Agreement temperature goals, the IMO’s upcoming revision of its GHG strategy should include a year by which emissions must be zero and interim targets.
Details matter: The outsized climate benefits of setting annual targets for new cars in Europe
This blog uses recent ICCT modeling of the post-2020 European Union CO2 standards to quantify just how large the climate benefits of setting annual CO2 targets would be.
Decarbonizing India’s road transport sector: Shouldn’t we aim higher?
Even the High Ambition scenarios in India’s road transport models are far from the limit in terms of what the country can achieve.
Vehicle electrification in India: On ambition and timing
Electrification is a key component of any future in which the growth in India’s road transport emissions is reversed.
[Updated] Choose wisely: IMO’s carbon intensity target could be the difference between rising or falling shipping emissions this decade
IMO member states’ choice of carbon intensity target matters a great deal.
