Without it, they could target the wrong emissions sources in their landscape for emission reduction or think they are on an emissions trajectory to meet their target, when in fact, they are not.\u201d<\/p>\n<p>He added that this accuracy is also crucial to getting and keeping citizens on board with climate action.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Methods_vary\"><\/span>Methods vary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Cities typically estimate their GHG emissions using tools such as the<span>\u00a0<\/span><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/icleiusa.org\/u-s-cities-are-not-vastly-undercounting-emissions\/\">US Community Protocol for Accounting and Reporting of Greenhouse Gas Emissions,<span>\u00a0<\/span><\/a>developed by ICLEI; the<span>\u00a0<\/span><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/ghgprotocol.org\/greenhouse-gas-protocol-accounting-reporting-standard-cities\">Global Protocol for Community-Scale Greenhouse Gas Emissions Inventories (GPC)<\/a>, developed by the World Resources Institute, C40 Cities Climate Leadership Group and ICLEI; and the<span>\u00a0<\/span><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.globalcovenantofmayors.org\/wp-content\/uploads\/2019\/04\/FINAL_Data-TWG_Reporting-Framework_website_FINAL-13-Sept-2018_for-translation.pdf\">Global Covenant of Mayors Common Reporting Framework.<\/a><\/p>\n<p>The process remains complex, though, and methodologies still differ. The report highlights key areas of variance such as accounting for shipping and airborne emissions and on-road emissions, for instance.<\/p>\n<p>Further, cities may miss or exclude certain categories due to data challenges or resource constraints.<\/p>\n<p>The Vulcan tool, which Gurney and a team of <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">science<\/a> and climate specialists, have developed over 15 years offers a standardized system for quantifying greenhouse gas emissions.

It uses around 30 different datasets related to CO2 emissions, including federal databases, regulatory data, Highway Administration data, energy statistics, and fuel consumption figures, as well as information on land parcels, buildings, traffic, and demographics.<\/p>\n<p>\u201cIt really is a giant mixture of different datasets that we bring together, and then we try to place the emissions as best we can in space and time across the whole landscape,\u201d Gurney said.<\/p>\n<p>The results from Vulcan are compared to atmospheric measurements to confirm accuracy.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Next_steps\"><\/span>Next steps<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Gurney says the system can also help cities better prioritize and target their climate actions down to the specific pieces of roadway or buildings that are creating the most emissions. In one city, for instance, the tool shows that around 10% of the physical road surface accounts for 60<span style=\"color: #030303;\">%<\/span>\u00a0of on-road CO2 emissions. With this insight, cities could achieve results faster and at a lower cost.<\/p>\n<p>Gurney is pushing for federal agencies in the US and global organizations more widely to consider adopting Vulcan as a systematic way to track emissions.<\/p>\n<p>He uses the analogy of the weather: \u201cIn the same way that we wouldn\u2019t expect every city or state to collect weather data, run a weather model and figure out their own weather, it doesn\u2019t seem very efficient to have every single city engaging in this redundant activity, which is costly, tedious and very time-consuming. We have a centralized system that we\u2019ve built much like a weather forecast system, and we can make this foundational data available to everybody.\u201d<\/p>\n<p>Laura Jay, C40\u2019s Regional Director for North America, told<span>\u00a0<\/span><em>Cities Today<\/em>: \u201cThe report underscores how critical cities are to addressing the climate crisis. It also makes an important case for a strong partnership between the federal government, states, and cities with a focus on which specific emissions each level of government can most effectively address, as well as cities working closely with the business community to bring down emissions from all sectors.<\/p>\n<p>\u201cWe welcome any new insights that can improve our efforts to reduce emissions, particularly those within cities\u2019 direct control.\u201d<\/p>\n<p>The next steps for Gurney and his team are looking at \u2018scope 3 emissions\u2019 in the value chain, as well as globalizing the research using remote sensing.<\/p>\n<p><em>Cities Today<\/em>\u00a0has contacted the cities of Cleveland and Palo Alto for comment.<\/p>\n<p><strong>Update (Feb 11):<\/strong><span>\u00a0<\/span>ICLEI published a<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/icleiusa.org\/u-s-cities-are-not-vastly-undercounting-emissions\/\"><span>\u00a0<\/span>response<\/a><span>\u00a0<\/span>to the paper in<span>\u00a0<\/span><em>Nature Communications<\/em>, including a Technical FAQ.
