The modal split for freight transport varies greatly by region, and is largely determined by geographical and economic factors. However there is a common trend towards more use of road transport, at the expense of rail and water transport. The latter modes have a substantially better environmental profile, but are limited by longer delivery times and the necessity of pre- and post-haulage by truck, i.e. inter-modal transport. In the logistic chain used nowadays, there are small local stocks and fast on demand delivery is required.

Improved air traffic management techniques like to avoid flying holding patterns, “green landings” and the use of relatively low speed airplanes for domestic aviation can reduce the emission of greenhouse gases substantially. Depending on their penetration up to 3% CO2 emission reduction can be achieved for green landings and 10-60% CO2 emission reduction for low speed airplanes. Moreover, these techniques will lower the NOx and soot emissions, thereby improving the air quality around the airport.

LNG consists mainly of methane, which has a boiling point of –164 0C and for liquefaction requires cryogenic insulated tanks at about atmospheric pressure. Recent practice has been to liquefy the gas that is normally flared in oil fields in remote areas, but it can also be made from landfill gas when purified. LNG is about 1/614th the volume of natural gas at standard temperature and pressure, making it much more cost-efficient to transport over long distances, especially where pipelines do not exist. Similar to LPG, this portability is a major asset.

The iron and steel sector is the second-largest industrial user of energy, consuming 616 Mtoe in 2007 and is also the largest industrial source of CO2 emissions. The five most important producers – China, Japan, the United States, the European Union and Russia – account for over 70% of total world steel production. A standard technique that is applied worldwide is the coke wet quenching of coke, where quenching vapors are bunkered before delivery to the atmosphere and subsequently or immediately a condensate is drawn off and cooled further.

CCS is a new technology, not yet proven at the industrial scale in cement production, but potentially promising. CO2 is captured as it is emitted, compressed to a liquid, then transported in pipelines to be permanently stored deep underground.
