Not only does it take up valuable land, but waste also produces methane, making it responsible for 5% of GHG emissions globally.<\/p>\n<p class=\"graf graf--p\">While there are about<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/unhabitat.org\/sites\/default\/files\/2022\/06\/wcr_2022.pdf\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/unhabitat.org\/sites\/default\/files\/2022\/06\/wcr_2022.pdf\"> 14,000<\/a> cities around the world contributing to this problem, a recent report found that 25 mega cities (almost half of them in China) produce<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.frontiersin.org\/articles\/10.3389\/frsc.2021.696381\/full#h4\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/www.frontiersin.org\/articles\/10.3389\/frsc.2021.696381\/full#h4\"> 52%<\/a> of global GHG emissions.<\/p>\n<p class=\"graf graf--p\">Here\u2019s a look at the big polluters and some green solutions they\u2019re employing to make these sprawling, urban areas cleaner and more livable.<\/p>\n<h2 class=\"graf graf--p\">1. Air pollution in Beijing<\/h2>\n<p class=\"graf graf--p\">Home to around 21 million people, Beijing is one of the top 10 polluters, primarily due to industrial buildings and on-road transportation. For this reason, air pollution has been a significant area of focus for Beijing since the<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.weforum.org\/agenda\/2021\/02\/china-tackling-air-pollution-big-data\/\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/www.weforum.org\/agenda\/2021\/02\/china-tackling-air-pollution-big-data\/\"> 2008 Olympics<\/a>.<\/p>\n<p class=\"graf graf--p\">Entrepreneurs in<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.entrepreneur.com\/en-au\/entrepreneurs\/a-breath-of-fresh-air-in-the-great-wall-of-china\/322058\" target=\"_blank\" rel=\"follow noopener\" data-href=\"https:\/\/www.entrepreneur.com\/en-au\/entrepreneurs\/a-breath-of-fresh-air-in-the-great-wall-of-china\/322058\"> China<\/a> are working to help people deal with toxic air, launching companies that create everything from air filters for homes, which use sensors to detect pollution and fans to direct that pollution out of the home, to bottled air designed to give people a hit of oxygen on particularly polluted days.<\/p>\n<p class=\"graf graf--p\">These startups may be doing wonders for individual health, but there\u2019s still an opportunity for businesses to help prevent pollution by increasing energy efficiency or<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.entrepreneur.com\/en-au\/news-and-trends\/didi-chuxing-signs-joint-venture-to-drive-electric\/327143\" target=\"_blank\" rel=\"follow noopener\" data-href=\"https:\/\/www.entrepreneur.com\/en-au\/news-and-trends\/didi-chuxing-signs-joint-venture-to-drive-electric\/327143\"> decarbonizing transport<\/a>.<\/p>\n<h2 class=\"graf graf--p\">2. Transportation emissions in Los Angeles<\/h2>\n<p class=\"graf graf--p\">Los Angeles is known for its sprawling, 6-lane freeways and epic traffic jams. Like Beijing, on-road transportation accounts for a substantial amount of Los Angeles\u2019s GHG emissions,<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/ladot.lacity.org\/livable-streets\/green-new-deal-la\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/ladot.lacity.org\/livable-streets\/green-new-deal-la\"> 19%<\/a> to be exact.<\/p>\n<p class=\"graf graf--p\">Gasonline-powered private vehicles and industrial trucking that use fossil fuels account for most of LA\u2019s on-road pollution, including GHG emissions, air pollutants, and heat and noise pollution.<\/p>\n<p class=\"graf graf--p\">But new technologies are in the works that help get people where they need to go while reducing private vehicle trips. <a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.numo.global\/micromobility\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/www.numo.global\/micromobility\">Micromobility<\/a> projects, such as bike shares and scooters, allow people to ditch cars and rideshares for shorter trips using these smaller, zero-emission vehicles. Apps like <a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/moovitapp.com\/\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/moovitapp.com\/\">Moovit<\/a>, a map platform that improves access to public transportation by giving live updates on public transport services, get people out of cars and onto environmentally friendly transit options.<\/p>\n<p class=\"graf graf--p\">The government is also being proactive. Last month, California air quality officials released a bold climate plan that requires California\u2019s emissions to be reduced by at least 40% by 2030 and 85% by 2045. The plan includes a rule that all new passenger vehicle sales in California will be zero-emission or long-range hybrid by 2035.<\/p>\n<h2 class=\"graf graf--p\">3. Waste in New York<\/h2>\n<p class=\"graf graf--p\">While buildings and transportation account for most of New York\u2019s GHG emissions, waste comes in third, accounting for<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.c40knowledgehub.org\/s\/article\/Why-cities-need-to-advance-towards-zero-waste?language=en_US\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/www.c40knowledgehub.org\/s\/article\/Why-cities-need-to-advance-towards-zero-waste?language=en_US\"> 5%<\/a> of the Big Apple\u2019s total GHG emissions. In general, Americans waste <em class=\"markup--em markup--p-em\">a lot<\/em>. The average American produces 2 kg of waste daily, up to 809 kg annually.<\/p>\n<p class=\"graf graf--p\">The good news for businesses is that sustainable waste strategies create ten times more jobs than sending waste to landfills or burning it. Today New York City is only recycling<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.curbed.com\/2022\/08\/nyc-trash-landfill-incineration-recycling-compost-voyage-gross.html\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/www.curbed.com\/2022\/08\/nyc-trash-landfill-incineration-recycling-compost-voyage-gross.html\"> 17%<\/a> of its waste and composting 1.4%. Food waste has been a particularly stubborn problem for the city. Despite government-backed food waste challenges and bills curbing restaurant waste, the city continues to struggle as <a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/nylcv.org\/news\/nyc-needs-common-sense-waste-management-now\/\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/nylcv.org\/news\/nyc-needs-common-sense-waste-management-now\/\">advocates<\/a> call for more robust, reliable, and accessible composting.<\/p>\n<p class=\"graf graf--p\">Companies are developing technologies to combat this food waste problem. <a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.entrepreneur.com\/leadership\/this-startup-plans-to-revolutionize-the-way-we-recycle-food\/280222\" target=\"_blank\" rel=\"follow noopener\" data-href=\"https:\/\/www.entrepreneur.com\/leadership\/this-startup-plans-to-revolutionize-the-way-we-recycle-food\/280222\">One startup<\/a> created a process to grind up old food and use digestive enzymes to turn it into fertilizer within three hours. Other companies are working to stop the problem at their source with <a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.entrepreneur.com\/en-in\/technology\/how-zero-waste-production-is-becoming-a-reality-in-the\/356939\" target=\"_blank\" rel=\"follow noopener\" data-href=\"https:\/\/www.entrepreneur.com\/en-in\/technology\/how-zero-waste-production-is-becoming-a-reality-in-the\/356939\">Zero Waste Manufacturing<\/a>. This strategy centers on reducing and reusing materials throughout the supply chain to achieve optimal levels of consumption.<\/p>\n<h2 class=\"graf graf--p\">4. Building efficiency in Frankfurt<\/h2>\n<p class=\"graf graf--p\">In Frankfurt, Germany, industrial, commercial, and residential buildings contribute substantially to GHG emissions.<\/p>\n<p class=\"graf graf--p\">Increasing efficiency can play a major role in reducing these emissions. <a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.entrepreneur.com\/en-in\/technology\/how-right-technologies-enable-efficiency-in-smart-cities\/333051\" target=\"_blank\" rel=\"follow noopener\" data-href=\"https:\/\/www.entrepreneur.com\/en-in\/technology\/how-right-technologies-enable-efficiency-in-smart-cities\/333051\">Smart city<\/a> initiatives are one-way cities like Frankfurt increase their efficiency and improve their quality of life. <a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/frankfurt.de\/themen\/digitalisierung\/smart-city-frankfurt\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/frankfurt.de\/themen\/digitalisierung\/smart-city-frankfurt\">Smart City Frankfurt<\/a> worked with businesses, scientists, and citizens to identify 12 priorities that needed attention. They included intelligent traffic control, which reduces emissions from idling, smart heating for houses, which reduces unnecessary energy use, and improved environmental and health data.<\/p>\n<p class=\"graf graf--p\">Not only do these initiatives help cities reduce emissions, but they also hold opportunities for new businesses to jump in and help develop new technologies. As global temperatures rise, cities will find themselves with new problems to manage, and demand for smart solutions will grow.<\/p>\n<p class=\"graf graf--p\">If you want to know more about how your own city ranks in air pollution, check out<a class=\"markup--anchor markup--p-anchor\" href=\"https:\/\/www.iqair.com\/us\/world-air-quality-ranking\" target=\"_blank\" rel=\"nofollow noopener\" data-href=\"https:\/\/www.iqair.com\/us\/world-air-quality-ranking\"> IQ Air<\/a>.<\/p>\n<p>&nbsp;<\/p>\n<p><strong class=\"markup--strong markup--p-strong\"><em class=\"markup--em markup--p-em\">Thanks for reading!
