A transparent assessment of the current new passenger vehicle market in South Africa in terms of CO2 emissions, and provides an evaluation of the benefits of adopting fuel economy and CO2 emission standards in those vehicles.

Summarizes the potential in Europe of presently available efficiency technologies to produce fuel savings that greatly exceed the upfront costs of technology and maintenance, and evaluates emerging advanced efficiency technologies that offer even more substantial fuel savings and short payback periods over the long term.

Compares the fuel efficiency of 20 airlines operating nonstop flights between the mainland United States and East Asia and Oceania and extends the previous transatlantic fuel efficiency methodology to the transpacific market.
