The France great addressed UEFA's 54 member federations and its executive committee to begin a four-day gathering in Dubrovnik, Croatia.
They will consider Europe's position on an expected FIFA decision next month that the 2022 World Cup in Qatar should move from summer to winter, threatening radical changes to the traditional football season.
Platini, who was elected to lead UEFA in 2007, faces his own re-election likely in March 2015.
"These elections are in two years' time and I think it would be egotistical to make it a topic for debate or discussion now when football faces much more important problems or issues than me or my situation," he said in a speech.
"I deeply love UEFA and it would be heartbreaking to choose another path. But at the same time, the question continuously pops up and it's a legitimate one. This is the reason why it's important for me to take my time, to make sure I take the right decision."
