In particular, high-income countries missed their 2020 target to mobilise $US100 billion per year.<\/p>\n\n<p>The Paris Agreement is a treaty but the pledges are voluntary. Countries set their own targets and can\u2019t be forced to meet them. So, is it working?<\/p>\n\n<p>According to this new report, it largely is \u2013 albeit slowly. For instance, it has encouraged nations such as Australia to make more ambitious emissions pledges.<\/p>\n\n<p>It has also enhanced transparency, enabling outside groups, such as those in civil society, to assess countries\u2019 progress.<\/p>\n\n<p>Other international mechanisms, such as global business partnerships and youth climate protests, are also driving change. <\/p>\n\n<p>But more must be done to halve emissions this decade.<\/p>\n\n<figure class=\"align-center zoomable\">\n            <a href=\"https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\" target=\"_blank\" rel=\"noopener\"><img  decoding=\"async\"  alt=\"\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-ls-sizes=\"(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\"  data-pk-src=\"https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\"  data-pk-srcset=\"https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=399&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=399&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=399&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=502&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=502&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/259050\/original\/file-20190214-1733-1tdsdqt.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=502&amp;fit=crop&amp;dpr=3 2262w\" ><\/a>\n            <figcaption>\n              <span class=\"caption\">School strikes are giving momentum to climate action.<\/span>\n              <span class=\"attribution\"><a class=\"source\" href=\"https:\/\/www.flickr.com\/photos\/160136040@N02\/32239704098\/in\/album-72157702588105781\/\" target=\"_blank\" rel=\"noopener\">Julian Meehan<\/a>, <a class=\"license\" href=\"http:\/\/creativecommons.org\/licenses\/by-sa\/4.0\/\" target=\"_blank\" rel=\"noopener\">CC BY-SA<\/a><\/span>\n            <\/figcaption>\n          <\/figure>\n\n<h2 id=\"cities-are-central\">Cities are central<\/h2>\n\n<ul>\n<li><em><strong>Xuemei Bai<\/strong>, lead author on urban systems and other settlements<\/em><\/li>\n<\/ul>\n\n<p>The IPCC report found around 70% of the world\u2019s greenhouse gas emissions are produced in cities and urban areas.
