Cities, which produce about 70% of carbon emissions, are driving green reforms and will be key to tackling climate change, the United Nations’ climate chief said on Thursday.
Their contribution to global warming could rise as two-thirds of the world will live in cities by 2050, up from about half now, the United Nations (U.N.) says.
“Cities are where the climate battle will be won or lost,” said Patricia Espinosa, executive secretary of the U.N. Framework Convention on Climate Change (UNFCCC), during a conference of city and government officials in Germany.
“We’re seeing an incredible momentum for action in cities,” she said, noting that city-level decisions, such as whether a local park would be built or electric buses installed, often felt more tangible to citizens than national reforms.
