About the ICCT

Our mission is to improve the environmental performance and energy efficiency of road, marine, and air transportation, in order to benefit public health and mitigate climate change.

Global demand for transportation is surging, and with it, inexorably, carbon emissions—not to mention other forms of air pollution. Transforming the technologies and systems that move people and goods around the world is an urgent imperative.

The International Council on Clean Transportation (ICCT) is an independent nonprofit organization founded in 2001 to provide first-rate, unbiased research and technical and scientific analysis to environmental regulators.

In the last five years alone, we have worked successfully with regulators and lawmakers around the world and have played a significant role in 48 distinct regulations and policies.


Together, these efforts are projected to result in billions of tons of carbon dioxide reductions and prevent thousands of premature deaths over the next decade and beyond.

Now, in little more than a generation, we must radically change a sector that almost exclusively depends on a single energy source—petroleum—operating on infrastructure that represents trillions of dollars of investment over decades.

In our Vision 2050 paper, we address four questions that are central to the ICCT’s vision for decarbonizing the global transportation sector.

1. What is the baseline trajectory of global transportation emissions from 2020 to 2050 by country and by vehicle segment?

2. What is the magnitude of reductions needed if the global transport sector is to contribute to keeping global temperature rise below 1.5°C?

3. What is an ambitious yet feasible set of policies and technologies for decarbonizing the transportation sector by mid-century?

4. What are the highest priority focus areas over the next five years?
