The European Parliament is backing proposals for a trust mark scheme to guarantee the quality and security of e-commerce web sites.
The trust mark will form part of plans to encourage cross-border e-commerce, and build consumer confidence in online shopping.
If the mark is accepted, it should be backed by all national trading standards groups and supported by their enforcement mechanisms, the Parliament said.
The European e-commerce industry is being held back by a lack of unity, and some traders still refuse to take orders from outside their own borders.
However, traders must also make the way they do business more transparent, as shoppers increasingly want to know the identity and contact details of the supplier.
This would be guaranteed under the trust mark, as would improvements to data privacy protection and electronic payment systems. The Parliament is also backing plans to use a Europe-wide database to help combat fraud.
"E-commerce is a tool with great potential to reshape and improve the competitiveness of the EU economy and the European internal market, and can provide great value and opportunities to European citizens and businesses at this time of financial strain," said Spanish MEP Pablo Arias Echeverria, one of the proposers of the scheme.
"It is vital that EU leaders implement the necessary measures to overcome remaining barriers to e-commerce, and create trust and transparency so that citizens and businesses can fully exploit its benefits."
