Energy-saving campaigns in most Western industrial countries have failed to curtail oil imports significantly or produce energy-efficient societies, an International Energy Agency report said yesterday.

The report, released in Paris, said that progress in implementing conservation programs has been considerably less than expected a year ago.

Countries are cutting back their oil-consumption rates, but it is due more to price increases than to self-imposed efforts to save energy, IEA executive director ULF Lantzke said. Western countries will have cut oil demand by their desired 5 percent by the end of the year, he said, largely due to the impact of recession, fuel shortages and higher oil prices.

Lantzke said the United States is performing better in energy conservation than it is generally given credit for. But the United States needs to step up its conservation efforts in order to meet its longer-run commitments by 1985, the report said. It urged the United States and Canada to raise gasoline prices -- which are only one-third of those in Italy, home of Europe's most expensive gasoline -- to stimulate fuel economy.

IEA officials said that President Carter's program of decontrolling oil prices would satisfy European countries that the United States is cooperating on the energy problem.
