Cities in developing countries are experiencing unprecedented urban growth. Unfortunately, this is often accompanied by the negative impacts of sprawl as a result of rapid motorization such as congestion, air pollution, greenhouse gas emissions, inefficient use of energy and time, and unequal accessibility.

The growth in BRT and bus priority systems worldwide presents an opportunity to save lives and improve the health and safety of cities. A new report, Traffic Safety on Bus Priority Systems, shows that high-quality public transport systems can improve traffic safety, reducing injuries and fatalities by as much 50 percent.

Global growth again disappointed in 2014 but a lackluster recovery is underway, with increasingly divergent prospects in major economies. Looking ahead, growth is expected to rise slowly, supported by continued recovery in high-income countries and receding domestic headwinds in developing economies.

The American Petroleum Institute broadened its fifth annual State of American Energy report as it included solar, nuclear, hydropower, wind, coal, geothermal, biomass, and energy efficiency as well as oil and gas.

This paper provides a summary of recent data for real-world fuel consumption of HDVs—specifically, tractor-trailers—in three regions: the United States, China, and the

This paper shows that any dedicated use of land for growing bioenergy inherently comes at the cost of not using that land for growing food or animal feed, or for storing carbon. It recommends several policy changes to phase out forms of bioenergy that use crops or that otherwise make dedicated use of land.

This paper reviews the evolution of biofuel policies in the United States, because it is by far the largest market for biofuels, and the European Union, because the use of oilseed crops for biodiesel, including palm oil, poses particular risks for tropical forests and for climate change.

This inaugural State of Clean Transport Policy report compiles advancements in national and international regulations to reduce energy use, mitigate climate change, and control
