LONDON, Sept 23 (Reuters) - The scandal over Volkswagen's falsification of car emissions in the United States further dims the outlook for what was once seen as the fuel of the future.

Unforeseen changes in fuel consumption in the world's fastest growing economies such as China, combined with a global economic slowdown and the rapid evolution of gasoline engines, have left the world with an excess of diesel just as huge state-of-the-art refineries switch on.

The crisis at VW has turned the spotlight on concerns that have gathered momentum in recent years -- particularly in Europe where diesel is the more common car fuel -- about air pollutants it produces and its credibility as a cleaner alternative to gasoline that cloud prospects for diesel carmakers.

"The focus was on low carbon emissions," said Chris Main, a commodities analyst with Citi in London. "One thing that wasn't seen was that you'd get other pollutants - such as nitrogen. People are starting to become more wary of diesel."

The impact of the VW scandal could, however, go far beyond the auto industry.

Refiners as well as many analysts have been caught off guard over the past year by the modest growth in diesel consumption compared with an insatiable thirst for gasoline from China to the United States, where the halving of oil prices since last June triggered a rapid growth in oil demand.

A slowdown in emerging economies that were expected to fuel the demand for diesel through rapid industrial growth, housing and infrastructure construction, further weakened diesel.

"It was a natural resort from the diesel shortage that we had seen in the past in the developing worlds. We did not realise that the growth pattern would be changing so much in China with less focus on industry and more focus on middle-class growth which is focused on gasoline vehicles," Olivier Abadie, Senior Oil Market Analyst for Refining at the International Energy Agency, told Reuters.

For example, Brazil's diesel imports plunged 95 percent in August as its commodities sectors contracted during a slowdown in nearly all global industrial sectors.

"The picture for diesel imports is not good," said Jose de Sa, head of oil and gas in Latin America for Bain & Company. "It's really the macroeconomic situation ... unfortunately, it's going to be like this for a while."
