U.N. Secretary General Ban Ki-moon on Jan. 28 called on the United States and Europe to take the lead in combating climate change, rather than waiting for others to act.
"This climate change campaign should be led, must be led by developed countries. This has started from industrial revolution, and the United States and European countries they have to be morally, politically responsible," Ban told world elites gathered at the Davos meeting of the World Economic Forum.
"The United States as a largest economy and superpower, this superpower of the world should take the political will, political leadership and invest in it," he added.
The United Nations chief pointed out that Washington should set its own house in order instead of waiting for others to take action.
"You have to do your own homework before waiting for others to do."
There are "psychological games" between the United States and Europe on one side, and China, India and Brazil on the other, said Ban.
"They ask you should do first. I think all the proposals are on the table.
"We know each other's pollution. I think they should be responsible for humanity, we have a responsibility to keep this world sustainable," said Ban.
Making a plea for action on climate change, Ban noted that the world has believed in "consumption without consequences" until now.
"Climate change is showing us that the old model is more than obsolete. It has rendered it extremely dangerous. It is a recipe for natural disaster. It is a global suicide attack," he charged.
