New data published by\u00a0Frontiers\u00a0highlights that 52% of urban greenhouse gas emissions are generated by just 25 megacities.<\/span>\u00a0<\/span><\/h2>\n

2015\u00a0saw the adoption of the Paris Agreement by\u00a0170 countries worldwide,\u00a0with the\u00a0aim of\u00a0curbing\u00a0the average global temperature increase to 1.5\u00b0C.\u00a0Subsequently,\u00a0many countries and cities\u00a0offered\u00a0targets for greenhouse gas mitigation.\u00a0<\/span>\u00a0<\/span><\/p>\n

However, the\u00a0<\/span>UNEP<\/span><\/a>\u00a0Emissions Gap Report 2020\u00a0has indicated\u00a0that,\u00a0short of\u00a0radical\u00a0and\u00a0comprehensive\u00a0actions to\u00a0alleviate\u00a0the climate crisis, we are\u00a0currently\u00a0moving\u00a0towards\u00a0a temperature increase of more than 3\u00b0C by the end of the 21st century.<\/span>\u00a0<\/span><\/p>\n

Studying urban greenhouse gas emissions<\/span>\u00a0<\/span><\/h3>\n

A novel study published in\u00a0<\/span>Frontiers Sustainable Cities<\/span><\/i><\/a>\u00a0offers the world\u2019s first global balance sheet of urban greenhouse gas emissions<\/span>,<\/span>\u00a0emitted by the world\u2019s major cities. The objective of the study was to examine the efficiency of historical greenhouse gas reduction policies\u00a0applied by 167 globally distributed cities that are at different developmental stages.\u00a0<\/span>\u00a0<\/span><\/p>\n

Despite occupying only 2% of the Earth\u2019s surface, cities are the biggest\u00a0contributors to the climate crisis.\u00a0However,\u00a0existing urban\u00a0greenhouse gas\u00a0alleviation targets are not adequate\u00a0for achieving\u00a0global climate change targets by the end of this century.\u00a0<\/span>\u00a0<\/span><\/p>\n

“Nowadays, more than 50% of the global population resides in cities. Cities are reported to be responsible for more than 70% of GHG emissions, and they share a big responsibility for the\u00a0<\/span>decarbonization\u00a0<\/span>decarboni<\/span>s<\/span>ation\u00a0<\/span>of the global economy. Current inventory methods used by cities vary globally, making it hard to assess and compare the progress of emission mitigation over time and space,”\u00a0explained\u00a0co-author Dr\u00a0Shaoqing\u00a0Chen, of Sun\u00a0Yat-sen\u00a0University, China.<\/span>\u00a0<\/span><\/p>\n

The researchers\u00a0performed sector-level\u00a0greenhouse gas\u00a0emission inventories of 167 cities, ranging from\u00a0metropolitan areas\u00a0like\u00a0Durban, South Africa, to cities such as Milan, Italy.\u00a0The scientists then\u00a0investigated and contrasted the carbon reduction progresses of the cities based on the emission inventories documented in different years (from 2012 to 2016).\u00a0<\/span><\/p>\n

Finally, they evaluated the cities’ short-, mid-, and long-term carbon alleviation goals. The cities were selected\u00a0from 53 countries\u00a0around the world\u00a0and were\u00a0chosen\u00a0based on representativeness in urban sizes and regional distribution. The degree of development was distinguished based on whether they belonged to developed and developing countries according to the UN classification criteria.<\/span>\u00a0<\/span><\/p>\n

The study\u2019s core findings<\/span>\u00a0<\/span><\/h3>\n
    \n
  1. 25 cities are responsible for 52% of the total urban greenhouse gas emissions.<\/span><\/li>\n
  2. Cities in the US, Europe and Australia had considerably higher per capita emissions than cities in developing areas.<\/span><\/li>\n
  3. Stationary energy and transportation were the two biggest causes of emissions.<\/span><\/li>\n
  4. Out of the 42 cities that had time-series traceable data, 30 reduced the annual greenhouse gas emissions during the study period. However, in several cities, there was an upsurge in emissions.<\/span><\/li>\n
  5. 113 of the 167 set differing types of greenhouse gas emission reduction targets, while 40 have set carbon neutrality goals.<\/span><\/li>\n<\/ol>\n

    The greatest polluters<\/span>\u00a0<\/span><\/h3>\n

    The team\u2019s finding<\/span>s<\/span>\u00a0indicated that\u00a0developed and developing countries alike have cities with high total greenhouse emissions, but that megacities<\/a> in Asia, for example, Shanghai in China and Tokyo in Japan, were particularly significant emitters. The inventory of per capita emissions highlighted\u00a0that cities\u00a0in Europe, the US, and Australia have greater emissions than most cities in developing countries, but China too has several cities where per capita emissions equa<\/span>l<\/span>led those of developed countries. It must also be considered that various developed countries outsource high carbon production chains to China, therefore heightening export-related emissions for the latter.<\/span>\u00a0<\/span><\/p>\n

    The research also found significant sources of greenhouse gas emissions: “Breaking down the emissions by sector can inform us what actions should be prioritised to reduce emissions from buildings, transportation, industrial processes and other sources,” explained Chen.\u00a0<\/span>\u00a0<\/span><\/p>\n

    Stationary energy \u2013 such as emissions from fuel combustion and electricity use in residential and institutional buildings, commercial buildings, and industrial buildings \u2013 accounted for 60 to 80% of total emissions in North American and European cities. In\u00a0<\/span>one\u00a0<\/span>one<\/span>–<\/span>third of the cities, over 30% of total emissions were from on-road transportation, and less than 15% of emissions were from railways, waterways, and aviation.<\/span>\u00a0<\/span><\/p>\n

    Finally, the results highlight that the levels of emissions rise and decline differed between the cities over the study period. For 30 cities, there was a clear-cut emission decrease between 2012 and 2016. The top four cities with the largest per capita decrease were Oslo, Houston, Seattle, and Bogot\u00e1. Meanwhile, the top four cities with the\u00a0greatest\u00a0per capita emissions increase were Rio de Janeiro, Curitiba, Johannesburg, and Venice.<\/span>\u00a0<\/span><\/p>\n

    Policy recommendations going forward<\/span>\u00a0<\/span><\/h3>\n

    The researchers made three core policy recommendations:\u00a0First: “Key emitting sectors should be identified and targeted for more effective mitigation strategies. For example, the differences in the roles that stationary energy use, transportation, household energy use, and waste treatments play for cities should be assessed,”\u00a0said Chen.<\/span><\/p>\n

    Next, is the development of\u00a0methodologically consistent global\u00a0greenhouse gas\u00a0emission inventories\u00a0to monitor the efficiency of urban greenhouse gas mitigation policies. Finally,\u00a0“Cities should set more ambitious and easily-traceable mitigation goals. At a certain stage, carbon intensity is a useful indicator showing the\u00a0<\/span>decarbonization\u00a0<\/span>decarboni<\/span>s<\/span>ation\u00a0<\/span>of the economy and provides better flexibility for cities of fast economic growth and increase in emission. But in the long run, switching from intensity mitigation targets to absolute mitigation targets is essential to achieve global carbon neutrality by 2050,”\u00a0Chen concluded.<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
