Aston University pollution expert praises Clean Air Zone roll out plans across UK
• Dr Stephen Worrall believes Birmingham’s Clean Air Zone is encouraging fewer drivers into city centre • The pollution expert said statistics show motorists are ‘changing their behaviour’ • He praised other cities for following suit but says changes need to come more quickly. A leading expert in air pollution from Aston University has examined available data on how many vehicles have paid to enter Birmingham’s Clean Air Zone (CAZ) and has said people’s behaviours are changing Atmospheric chemist, Dr Stephen Worrall, praised the introduction of Birmingham’s CAZ which launched on 1 June, saying it was an important step in tackling air pollution in the city and would have a considerable impact on people’s health. Whilst the full impact of the CAZ on pollution levels won’t become clear until 2022, Dr Worrall said since the “Go Live Date” the traffic data revealed that the number of non-compliant vehicles being driven in the zone was decreasing markedly. “In the first two weeks of June before charging was introduced, the daily number of non-compliant vehicles being driven within the CAZ was at an average of 18,787. “After charging was introduced, this dropped significantly to 11,850 for the remainder of June and this number has continued to fall, with the last reported daily average of 10,800 for August. “This isn’t just your average motorist with a car either, as the data shows similar trends for other categories of vehicles with the biggest improvement observed in light goods vehicles (LGVs). Over 75% of these vehicles were complying with the CAZ in August versus just 63% in June. This is a significant and sustained reduction which clearly demonstrates that people are modifying their behaviours,” he said. Dr Worrall added that the data was also able to hint at the manner in which people were modifying their behaviour, with a possible increase in public transport use, car sharing or a reduction in overall number of journeys. “Some people are upgrading their vehicles to newer, less polluting models as there has been a small rise of about 2,500 in the number of complaint vehicles entering the CAZ on a daily basis. However, this number is dwarfed by the approximately 8,500 reduction in the daily number of non-complaint vehicles. The upshot of this is that the total number of vehicles entering the CAZ every day has dropped by roughly 6,000 (around 6%). 6,000 fewer of the most polluting vehicles in our city centre is a real positive and a step in the right direction to improving our air quality and health,” he said. Air pollution particularly affects the most vulnerable in society, including children, and older people, and those with heart and lung conditions. The annual health cost to society of the impacts of particulate matter alone in the UK is estimated to be around £16 billion*. Levels of NO2 in Birmingham frequently exceed 45 to50 micrograms per cubic meter, mainly caused by road traffic emissions, with certain hotspots exhibiting even greater values such as the measuring site at St Chads Queensway where the last reported yearly average for the city centre was as high as 74 micrograms per cubic meter. The primary aim of the CAZ is to reduce the levels of NO2 to 40 micrograms per cubic meter. Dr Worrall said that although CAZs weren’t directly designed to address greenhouse gas emissions, if as suggested they result in less people using their vehicles for journey, then this would have an impact on emissions. “Whilst the CAZ target is to reduce nitrogen dioxide (NO2) levels, the knock-on effect of this reduction in car use will mean a reduction in pollution in general, including greenhouse gases such as CO2. This is really important and suggests that other cities need to be acting now rather than later. Bath has implemented a similar but less stringent system, London recently extended its ultra low emission zone (ULEZ) area and Portsmouth’s CAZ will be coming live shortly too, but other cities who have plans in the pipeline should really bring them forward as a matter of urgency,” he said. Dr Worrall added that with current COP26 discussions bringing pollution to the forefront, it was important to continue with awareness. “These policies are all small pieces in the puzzle for reducing emissions from transport and getting people to make wiser choices about the vehicles they own and buy, and as COP26 is making very clear we need to be doing all of these things now to save our planet” he said. Dr Worrall has great experience in the subject, having spent a portion of his post-doctoral research in Beijing where he took live air pollution measurements, monitored problematic levels and discussed with international colleagues’ ways to address these issues.

Aston University atmospheric chemist praises introduction of Birmingham’s Clean Air Zone
Dr Stephen Worrall has praised the introduction of the Clean Air Zone in Birmingham The expert in atmospheric chemistry said current levels within the city have to drop for the health of all Birmingham’s Clean Air Zone (CAZ) comes into effect on 1 June Dr Stephen Worrall is a lecturer in chemistry at Aston University A leading atmospheric chemist from Aston University has welcomed the introduction of Birmingham’s Clean Air Zone (CAZ) from 1 June 2021 and has said it will be an important step in tackling air pollution. Dr Stephen Worrall, a lecturer in chemistry in the College of Engineering and Physical Sciences, said the long-term effects of the change will be beneficial to people’s health throughout the city. Air pollution particularly affects the most vulnerable in society, including children and older people, and those with heart and lung conditions. The annual health cost to society of the impacts of particulate matter alone in the UK is estimated to be around £16 billion*. Dr Worrall said: “In my opinion the CAZ is undoubtedly a good idea. In many of our cities, but definitely in Birmingham, the levels of many types of pollution and especially nitrogen dioxide (NO2) are high and have been above the guideline levels for a very long time, so it is welcome that these changes are happening.” Dr Worrall said current levels of NO2 in Birmingham in May 2021 have frequently exceeded 45 – 50 micrograms per cubic meter, mainly caused by road traffic emissions. The last reported yearly average for the city centre was as high as 74 micrograms per cubic meter, taken from the measuring site at St Chads Queensway. The primary aim of the CAZ is to reduce the levels of NO2 to 40 micrograms per cubic meter. “What is interesting about 2020 is those levels were still quite high at times despite us being into lockdown, when there were significantly fewer vehicles on the road. The live, daily readings from this year are also often exceeding the recommended levels, both of which are telling,” he said. Dr Worrall has significant experience in the subject, having spent a portion of his post-doctoral research in Beijing where he took live air pollution measurements, monitored problematic levels and discussed with international colleagues’ ways to address these issues. He said: “I was working and living in a very polluted area of the city and it was very noticeable on a daily basis how polluted it was. The levels of NO2 in 2017 while I was there were on average 103 micrograms per cubic meter, which was very high.” Dr Worrall added he believed the CAZ would have a big impact on Birmingham’s overall health but that the situation needed to be closely monitored. “There is significant evidence to suggest that there are serious long term health issues that arise from breathing in high levels of NO2, as well as Particle Matter (PM), an air pollutant which is absorbed into the blood stream through penetrating the lungs. These include asthma, bronchitis, lung cancer, heart disease and strokes. “Whilst there is local concern about the economic impact of the CAZ which must be taken into account, reducing these levels will benefit all of us, particularly those living in areas of deprivation who have been shown to be most significantly harmed by these high levels of pollution, as Birmingham’s biggest cause of pollution is from cars,” he said.

Taking on Super Polluters to Reduce Greenhouse Gases
If just the top five percent of carbon-emitting plants in the U.S. reduced emissions to the average intensity of all plants, overall emissions from the electricity sector would fall 22 percent. A new book co-authored by Wesley Longhofer, associate professor of organization and management at Goizueta Business School, offers new insights into a persistent problem—how to curb carbon emissions from top-polluting power plants around the world. In Super Polluters: Tackling the World’s Largest Sites of Climate-Disrupting Emissions (Columbia University Press), Longhofer and co-authors Don Grant and Andrew Jorgenson argue that reducing pollution from fossil-fueled power plants should start with the dirtiest producers. From data they gathered over eight years on the carbon emissions of every power plant in the world, they found that a small number of plants contribute the lion’s share of pollution. For instance, if just the top five percent of carbon-emitting plants in the U.S. reduced emissions to the average intensity of all plants, overall emissions from the electricity sector would fall 22 percent. The book also questions claims that improvements in technical efficiency will always reduce greenhouse gases. “It’s the paradox of efficiency,” Longhofer says. “Just because a plant produces power more efficiently doesn’t mean they’ll pollute less. It just becomes cheaper to produce.” As sociologists, the authors are the first to put the problem into context, investigating global, organizational, and political conditions that explain super-polluter behavior. They demonstrate energy and climate policies most effective at curbing power-plant pollution and show how mobilized citizen activism shapes those outcomes. “Climate change is fundamentally an organizational problem. Even if you think about the Paris Accords, it’s the power plants and the cars within those states that produce the emissions, not the states themselves,” Longhofer says. “What do we do with what we already know? How do we develop policies to help us achieve our climate goals?” If you’re a journalist looking to speak with Wesley Longhofer about his book or discuss big pollution and how to cut carb emissions - then let us help.

Wastewater Hazards in Southwest Florida Spark Environmental Concerns Across the State and Beyond
Over the last week hundreds of millions of gallons of wastewater have spewed from a former fertilizer plant in Piney Point, Florida, which was abandoned in 2001 and taken over in 2006 by the Florida Department of Environmental Protection. The location is adjacent to Tampa Bay, a 400-square-mile body of water that separates Tampa, Clearwater and St. Petersburg and is full of fish, crabs, seagrass, dolphins, manatees and seabirds of every kind. The state plans to close Piney Point, scientists are trying to forecast what comes next and environmentalists fear algal blooms and fish kills (also known as fish die-offs). “There are hundreds if not thousands of these waste storage ponds in the United States and each one is a ticking time bomb,” says Villanova University’s Metin Duran, PhD, an expert on the biological processes of environmental engineering, including public health microbiology and biological processes for waste management. “The last major disaster was in December 2008, when a 40-acre pond used by Tennessee Valley Authority for the coal-burning Kingston Fossil Plant collapsed. The aftermath included damage to the area’s ecosystem and lawsuits.” Regulations regarding waste storage ponds are at the state level, and they aren’t very strict, says Dr. Duran. “Though there are strict design and groundwater monitoring requirements to ensure waste does not cause groundwater pollution, these waste impoundments are prone to have issues under extreme weather events, such as heavy rains. With the increased frequency of such events recently, there is a risk that more of such may fail.” Dr. Duran adds that it can be difficult to predict short- and long-term effects of the Florida case, but the reported low-level radioactive contamination could cause major damage to aquatic life and properties—and that phosphorous and nitrogen would cause eutrophication in Tampa Bay as well.
It’s as if there’s an all-out war on the world’s insects – and experts from across the country are all buzzing with some very bad news. Recently, University of Connecticut’s Professor of Ecology and Evolutionary Behavior, David Wagner was featured on CBS National News in an in-depth story about the potential apocalypse the world’s insect kingdom faces. “The world's vital insect kingdom is undergoing "death by a thousand cuts," the world's top bug experts said. Climate change, insecticides, herbicides, light pollution, invasive species and changes in agriculture and land use are causing Earth to lose probably 1% to 2% of its insects each year, said University of Connecticut entomologist David Wagner, lead author in the special package of 12 studies in Monday's Proceedings of the National Academies of Sciences written by 56 scientists from around the globe. The problem, sometimes called the insect apocalypse, is like a jigsaw puzzle. And scientists say they still don't have all the pieces, so they have trouble grasping its enormity and complexity and getting the world to notice and do something. Wagner said scientists need to figure out if the rate of the insect loss is bigger than with other species. "There is some reason to worry more," he added, "because they are the target of attack" with insecticides, herbicides and light pollution… Insects "are absolutely the fabric by which Mother Nature and the tree of life are built," Wagner said. January 12 - CBS News The story is attached above – and must-read material for anyone concerned about insects and the vital role they play in just about every aspect of our world.

Can America’s Infrastructure Withstand The Digital Economy?
When a city like New York is facing a continuous delivery stream of more than 1.5 million packages a day, something has to give. The growing number of sales by Amazon and other online retailers, combined with rapid delivery options, is choking streets within major metropolitan cities. This issue was recently featured in The New York Times — and when the journalists needed an expert perspective, they contacted Rensselaer Polytechnic Institute. Here's an excerpt: The average number of daily deliveries to households in New York City tripled to more than 1.1 million shipments from 2009 to 2017, the latest year for which data was available, according to the Rensselaer Polytechnic Institute Center of Excellence for Sustainable Urban Freight Systems. “It is impossible to triple the amount,” said José Holguín-Veras, the center’s director and an engineering professor at Rensselaer, “without paying consequences.” Households now receive more shipments than businesses, pushing trucks into neighborhoods where they had rarely ventured. And it could be just the beginning. Just 10 percent of all retail transactions in the United States during the first quarter of 2019 were made online, up from 4 percent a decade ago, according to the Census Bureau. — The New York Times, October 28, 2019 If you are a reporter covering this or a similar topic, let our experts help!

August is National Breastfeeding Month – Let our Experts Help with Your Coverage
It’s August…a month that celebrates breastfeeding and all the benefits that come with it. Breastfeeding is natural, healthy and cost-effective – and the American public is beginning to recognize a mother’s right to feed her child wherever and whenever she wants. Breastfeeding is a great benefit to the environment and society, according to the American Academy of Pediatrics. Breastfeeding families are sick less often and the parents miss less work. It does not require the use of energy for manufacturing or create waste or air pollution. There is no risk of contamination and it is always at the right temperature and ready to feed. A new website developed by researchers in Canada and Asia showed that the world could have saved $341 billion each year if mothers breastfeed their children for longer, helping prevent early deaths and various diseases, according to a July 12 article from Reuters. Known as the “Cost of Not Breastfeeding,” the online tool used data from a six-year study supported by the U.S.-based maternal and child nutrition initiative, Alive & Thrive. According to Augusta University Health’s Dr. Kathryn Strickler McLeod, breastfeeding protects against a variety of diseases and conditions in the infant, including diarrhea, respiratory tract infection, childhood obesity and much more. Additionally, there are also maternal health benefits to breastfeeding, including a decreased risk of breast and ovarian cancers.

There’s no question about it – our planet has a problem with plastic. Though simple, cheap, convenient and often necessary, the reality is single use and non-reusable plastics like straws, plastic bags, wrapping and most containers are causing problems. There’s no hiding or ignoring the evidence – plastic is everywhere from landfills, to our rivers and streams and even occupying its own land mass in the ocean. Recently Canada proposed a ban on single use plastics to come in to effect in 2021. The country joined the likes of France, Germany, Italy, the U.K. and the European Union who are all implementing similar policies. The United States, however – has not. Here are some facts from the Center for Biological Diversity. Americans use 100 billion plastic bags a year, which require 12 million barrels of oil to manufacture. The average American family takes home almost 1,500 plastic shopping bags a year. According to Waste Management, only 1 percent of plastic bags are returned for recycling. That means that the average family only recycles 15 bags a year; the rest ends up in landfills as litter. Up to 80 percent of ocean plastic pollution enters the ocean from land. 100,000 marine animals are killed by plastic bags annually. One in three leatherback sea turtles have been found with plastic in their stomachs. Plastic bags are used for an average of 12 minutes. It takes 500 (or more) years for a plastic bag to degrade in a landfill. Unfortunately, the bags don't break down completely but instead photo-degrade, becoming microplastics that absorb toxins and continue to pollute the environment There is no doubt plastic is a serious problem in America – but will the country join in? What will it take from an industry point of view? Will costs outweigh the benefit? Is this a matter of regulation and do Americans have the appetite to make this a political issue?
