Beyond trucks: Toward a greener global freight transportation system
Reducing emissions of the freight sector calls for looking beyond strategies focused on trucks to explore more holistic solutions, like modal shifts from road to railway and waterway and intermodal transportation.


Why and how to bring down the cost of SAF
Today, sustainable aviation fuel (SAF) generally costs between 2 and 5 times more than fossil jet fuel.

Why SAF is expected to play a larger role in near- and medium-term decarbonization than zero-emission aircraft
As the aviation industry works toward net-zero carbon emissions by mid-century, one thing is clear: sustainable aviation fuels (SAFs) are expected to be the primary decarbonization lever.

Cloudy with a chance of soot: The role of fuel composition in aviation’s non-CO2 impact
Robust sustainability criteria prioritizing minimal life-cycle carbon intensity can help to ensure that sustainable aviation fuels (SAFs) are truly low carbon, which is crucial to achieving aviation’s 2050 net-zero target.

Who gets credit when SAF is used on a flight?
How do airlines know how much SAF is used on their flights, and how does SAF use by airlines affect your personal carbon footprint? Welcome to the world of SAF accounting.

Understanding the greenhouse gas emissions of different SAF pathways
We can understand the differing greenhouse gas (GHG) emission benefits of using sustainable aviation fuels (SAFs) by comparing their life-cycle emissions with the emissions of fossil jet fuel.

Why reconsider counting SAF combustion as carbon neutral?
In this piece, we explore an accounting convention adopted by the Intergovernmental Panel on Climate Change (IPCC) and most regulators, including the International Civil Aviation Organization, that treats biofuel combustion emissions as zero.

Driving change: Maharastra’s EV push lacks low emission zone strategy
Maharashtra’s 2025 EV policy allocates ₹1,993 crores over five years to boost purchase subsidies, EV infrastructure and manufacturing with the goal of achieving 30% of all new vehicle registrations to be electric by 2030, but it omits low-emission zones (LEZs) that could strengthen the state’s leadership in India’s sustainable mobility transition.

Ten Years After Dieselgate: Transportation’s Unfinished Business
Ten years after ICCT exposed Volkswagen’s Dieselgate scandal—revealing diesel vehicles emitting up to 35 times legal limits—significant progress has been made with improved compliance and surging EV adoption, yet millions of high-emitting vehicles remain on roads. Despite Europe’s diesel share dropping from 52% to 18% while EVs reached 25%, transportation’s unfinished business offers tremendous opportunity as electric vehicles reach cost parity and accelerate the transition to inherently clean transportation.

India’s transport transformation: Three policies to shape the road ahead
India today stands at a remarkable turning point in its mobility journey. Transport is no longer seen as a background sector—it is becoming a central pillar in India’s ambition to become a developed economy, a Viksit Bharat, by 2047, while meeting its net-zero target by 2070. Three recent policy moves in 2025 have the potential to transform India’s transport landscape, offering a blueprint for a cleaner, more efficient, and future-ready system.

What’s next for China’s PHEV market?
China’s electric vehicle market, once dominated by BEVs, has seen a dramatic surge in PHEV sales underpinned by supportive policies—though emerging policy developments raise questions over the market’s long-term outlook.
