Economic model 'transformation' needed: UN climate envoy

A dramatic transformation of the global economic model will be necessary if the world truly wants to tackle the problem of climate change, a top UN envoy said Friday.

"We need bold actions," insisted Luis Alfonso de Alba, who was appointed late last year to prepare an ambitious climate summit in New York in September.

In an interview with AFP in Geneva Friday, he stressed that climate change should not be merely considered an environmental problem.

"We are talking about a transformation of the economic model that is going to be needed to achieve the results we need," he said.

The September 23 summit at the United Nations is billed as the first major stocktaking gathering of world leaders on climate change since the Paris agreement was reached in 2015.

The event follows a string of reports containing dire predictions about the future of the planet as carbon dioxide emissions continue to rise, pushing targets set out under the Paris accord further out of reach.

UN Secretary-General Antonio Guterres has said he wants the summit to be "action oriented", and he has asked countries to present "concrete, realistic plans" to reduce greenhouse gas emissions by 45 percent over the next decade and to net zero by 2050.

De Alba said he was working to identify ambitious projects to showcase at the September meeting, as well as new models of cooperation and coordination between countries, organisations and public and private players.

"It is evident that private financing will be indispensable to move from the billions to the trillions that are going to be needed," he said.

Fighting climate change he said, "is an issue that requires a transformation of the way we consume, the way we produce." "This is not a process in which we can aim at a gradual increase of the ambitions. We need some drastic changes."
