Descriptions Fuel Efficiency Improvements

We study the interactions between fuel efficiency improvements in the transport sector and the oil market, where the efficiency improvements are policy-induced in certain regions of the world. We are especially interested in feedback mechanisms of fuel efficiency such as the rebound effect, carbon leakages and the “green paradox”, but also the distributional effects via oil price changes for different regions, sectors and oil producers. An intertemporal numerical model of the international oil market is introduced, where OPEC-Core producers have market power. We find that the rebound effect has a noticeable effect on the transport sector, but also on other sectors through lower oil prices in the regions that introduce the policy. There is a small green paradox effect in the sense that oil consumption increases initially when the fuel efficiency measures are gradually implemented. Finally, there will be significant carbon leakages if the policy is not implemented in all regions, with leakage rates of 35 per cent or higher. Non-OPEC producers will suffer more than OPEC producers by fuel efficiency policies due to high production costs.

An electronic book, also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book",some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, but also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones.

Airline fuel efficiency: 'If you can't measure it, you can't improve it - The fuel burn of US passenger aircraft fell by an average of 0.4% per year between 2005 and 2019 due to technology improvements. These account for approximately one-quarter of the total fuel efficiency improvement. Payload efficiency is a measure of how well airlines fill their aircraft with passengers and freight. This can be done through
