35 Mobilizing Sustainable Transport for Development<br />

newer aircraft and many retro-fitted aircraft now<br />

utilise winglet technology, devices fitted to the<br />

tips of aircraft wings that reduce drag and fuel<br />

consumption and related emissions. 74<br />

Sustainable Bio-Jet Fuel<br />

Maritime: In large freight and cruise ships, skysails<br />

and more energy efficient propulsion systems<br />

are showing promise, and shipping companies<br />

are using slow steaming to save both money and<br />

fuel. Ferry transport is becoming more efficient<br />

and “smart” with internet-connected surveillance<br />

cameras and radios; Global Positioning Systems;<br />

display monitors for passengers updated with real<br />

time information; and sensors that collect data on<br />

ridership, weather, speed and direction, and fuel<br />

use and maintenance needs. 75<br />

Rail: Railway energy efficiency has doubled since<br />

1975. Electrification has expanded to cover one-third<br />

of the global network and powers almost 45% of all<br />

rail activity. Rail companies are choosing to invest<br />

directly in renewable energy, which now powers more<br />

than 20% of electric powered trains. 76 Recuperative<br />

breaking, returning energy to the grid when trains<br />

slow down, is now state of the art. Rail companies<br />

also have a well-developed research program to<br />

develop further efficiencies, such as smart grids 77<br />

and other technologies.<br />

Road: Connectivity and integration of ICT into<br />

vehicles reduces congestion, reduces time delays,<br />

allows for real time adjustments for routing,<br />

enables tailor-made mobility solutions based<br />

on individual needs, connects the driver to work<br />

and families, and improves overall experience<br />

of the user. Collision avoidance and other driver<br />

assistance innovations are enhancing safety.<br />

Energy efficiency is improving through newer<br />

engine and aerodynamic design, and refinements<br />

in hybrid bus technology are enabling savings<br />

in fuel consumption of 30-40%. New renewable<br />

fuels as well as electricity are being introduced<br />

and autonomous driving such as “truck platoons”<br />

(a line of freight trucks traveling as a connected<br />

convoy that can separate and travel to their<br />

respective destinations) are developing.<br />

Systems<br />

Designing urban transport systems based on<br />

population density, usage data and other factors<br />

allows for more efficient investments in transport<br />

infrastructure built around high quality mass public<br />

transport. Investments in efficiently designed roads,<br />

airports, rail, and marine ports can reduce carbon<br />

emissions while providing greater mobility and access.<br />

International collaboration is particularly crucial in<br />

With an aim of reducing greenhouse gas emissions<br />

and realizing sustainable development benefits<br />

worldwide, the United States Federal Aviation<br />

Administration (FAA) and aviation industry are<br />

leading the effort to develop and deploy<br />

sustainable alternative jet fuel. The Commercial<br />

Aviation Alternative Fuels Initiative (CAAFI) serves<br />

as the driving force to make these fuels a reality.<br />

Among its accomplishments to date, CAAFI<br />

established a process to include alternative jet fuel<br />

in the industry’s fuel specifications, helped secure<br />

approvals under the specification for five such fuels<br />

with more currently undergoing review, developed<br />

an array of feedstock readiness and sustainability<br />

evaluative tools and guidance, and fostered<br />

agreements between airlines and fuel producers.<br />

Since CAAFI’s inception in 2006, the aviation<br />

industry has gone from test flights to commercial<br />

flights and now is working to scale up production<br />

of sustainable bio-jet fuel around the world, with<br />

sustainable feedstocks as diverse as non-edible<br />

plant oils, used cooking oil, agricultural waste,<br />

high-energy tobacco and municipal solid waste.<br />

The U.S. FAA and CAAFI have worked in partnership<br />

with initiatives around the world, such as<br />

Indonesia’s public-private Aviation Biofuels and<br />

Renewable Energy Task Force, which has completed<br />

feasibility studies and is preparing to generate<br />

commercial supply. The Indonesian government is<br />

working towards implementing a requirement that<br />

2% of aviation fuel be certified, sustainable biofuel<br />

by 2018 (3% by 2020). The International Civil<br />

Aviation Organization is also helping with capacity<br />

building under its Global Framework for Aviation<br />

Alternative Fuels.<br />
