In 1961 the European railways commissioned the standardization of a common pallet type under the auspices of the UIC.
Following the standardization, most of the European industry switched over to using Euro-pallets with trucks, forklifts, and high-rack warehouses optimized for their size.
With the success of the Euro-pallets, a number of replicas entered the market that used low-quality wood which splintered easily and were prone to mold, so the European railways, which own the trademarks for EUR/EPAL, created a separate standardization body.
It is still the most widespread pallet type in the world, with an estimate of 350 to 500 million EUR-pallets being in circulation.

The 45 ft (14 m) pallet-wide high-cube shortsea container has gained wide acceptance, as these containers can replace the A-Behälter swap bodies with a length of 13,670 mm (44 ft 10 in) that are common for truck transport in Europe.
The EU has started a standardization for pallet-wide containerization in the EILU (European Intermodal Loading Unit) initiative.
