The Entertainment and Leisure Software Publishers Association (ELSPA) has called on Europe to adopt a single rating system for video games.
Paul Jackson, director of ELSPA, told the Westminster Media Forum that the government must recognise the decisions made in the Byron Review of computer and video games.
Jackson is pushing for adoption of the Pan European Games Ratings Information (PEGI) as the de facto standard rating system across Europe.
"For the games industry, when we talk about child protection, we talk about PEGI. PEGI is the solution for today, and the solution for tomorrow," he said.
"Only PEGI fully assesses all games content. It is designed specifically for interactive software. It understands games and their potential for infinite variations. That's why it is backed by the vast majority of the computer games industry."
