Ban listed durability, flexibility, solidarity and credibility as the "four essential elements" for success in Paris.
Explaining durability, he said that the Paris summit "must send a clear signal to market that the low-carbon transformation of the global economy is inevitable and beneficial."
The deal to be reached in Paris must also be able to accommodate changes in the global economy while striking balance between the leadership role of developed countries and the increasing responsibilities of developing countries, he said, referring to flexibility.
The deal must show solidarity by providing financing and technology transfer for developing countries, Ban said, adding that developed countries must keep their pledge to provide 100 billion U.S. dollars a year by 2020 for both adaptation and mitigation.
To ensure its credibility, the deal must establish strong monitoring mechanisms, be able to respond to rapidly escalating climate impacts, and ensure the world is "on a path to a low carbon economy", he emphasized.
Climate change is expected to be one of the topics for the G20 leaders as they start their round-tables Sunday afternoon, which will wrap up on Monday.
The UN chief also urged the G20 leaders to give a robust response to recent terrorist attacks which rocked Paris Friday night, and show solidarity in the face of the largest refugee crisis in decades.
"I will stress to world leaders that our response needs to be robust, but always within the rule of law and with respect for human rights. Otherwise, we will only fan the fire we are trying to put out," he said.
As to the refugee crisis, he said, "I also count on G20 leaders for support as we address the biggest crisis of forced displacement since the Second World War."
"This is not only a crisis of numbers; it is a crisis of global solidarity," he added.
