Pollution's Impact On Real Estate: Value Drop

Pollution can have a significant impact on real estate values, affecting everything from a property's livability to its selling price. Noise pollution, for instance, can deter buyers and reduce property values, with sources like traffic, airports, and industrial activities causing the most significant decreases in value. Air pollution, which affects vegetation, soil quality, and human health, can also have a detrimental effect on real estate values, especially as public awareness of its health risks grows. Water pollution, whether from contaminated groundwater or acid rain, can impact the land and the health of those living on it. Ultimately, pollution can lead to a decrease in real estate values, with properties in polluted areas selling for lower prices compared to similar properties in less polluted locations.

Air pollution's impact on human health

Air pollution is a pressing issue that affects human health in numerous ways, and it is considered the single largest environmental health risk in Europe. It encompasses the presence of contaminants in the atmosphere, such as dust, fumes, gases, and smoke, which can have detrimental effects on individuals' respiratory systems and overall well-being. Here is an overview of how air pollution impacts human health:

Impact on Respiratory System: When inhaled, air pollutants can enter the bloodstream and irritate the respiratory tract, leading to coughing, itchy eyes, and breathing difficulties. Prolonged exposure to polluted air can cause or exacerbate lung diseases, including chronic obstructive pulmonary disease (COPD), emphysema, chronic bronchitis, and lung cancer. Fine particulate matter, such as PM2.5, is of particular concern as it can penetrate deep into the lungs and even enter the bloodstream, causing systemic damage to tissues and cells.

Cardiovascular Effects: Air pollution has been linked to an increased risk of cardiovascular problems, including heart disease, abnormal heartbeats, and stroke. The fine particles in polluted air can contribute to the development of cardiovascular diseases over time.

Neurological and Cognitive Impacts: Exposure to air pollution has been associated with adverse neurological and cognitive effects. There is evidence suggesting a link between air pollution and an increased risk of cognitive impairment, Alzheimer's disease, dementia, and other neurological diseases.

Pregnancy and Childhood Development: Maternal exposure to air pollution during pregnancy can lead to adverse birth outcomes, including low birth weight, pre-term birth, and small gestational age. Air pollution also poses risks to children's health, affecting their developing organs, immune systems, and increasing their susceptibility to respiratory infections.

Other Health Risks: Air pollution has been linked to various other health issues, including type 2 diabetes, obesity, systemic inflammation, and certain types of cancer. It can also aggravate existing conditions and increase the risk of premature death.

It is important to note that the impacts of air pollution on human health can vary depending on age, location, underlying health conditions, and socioeconomic factors. Vulnerable populations, such as children, the elderly, and people with pre-existing health conditions, are more susceptible to the adverse effects of air pollution.

To mitigate the impacts of air pollution on human health, individuals can take measures such as reducing exposure to polluted air, advocating for stricter air quality regulations, and adopting cleaner technologies and energy sources.

The effect of noise pollution on property values

Noise pollution can have a significant impact on property values, affecting both the selling price and rent charged for a property.

The World Health Organization (WHO) states that noise levels above 65 decibels (dB) are considered noise pollution, with noise above 75 dB being harmful, and above 120 dB painful. The WHO also estimates that ambient night-time noise levels of above 30 dB make it impossible to get a restful sleep.

Sources of noise pollution can include transport and machinery, such as planes, construction sites, and traffic, as well as social noise from busy bars and restaurants.

Noise pollution has been found to negatively impact the price of apartments, with railway noise causing the biggest nuisance. A Polish study found that every 1 dB increase above a 55 dB level caused a 1.79% decrease in the value of an apartment, while aviation noise caused a 0.59% decrease per decibel, and road noise a 0.12% drop.

However, the impact of noise pollution on property prices can vary depending on the location. For example, in busy city centres, higher noise levels may be associated with commercial areas and a vibrant nightlife, which can be desirable for some buyers. In contrast, quieter areas are generally deemed more desirable, particularly for residential properties and families.

When assessing the impact of noise pollution on property values, it is important to consider the surrounding area, the time of day, and the type of noise. Visiting the property at different times and assessing the potential noise sources, such as nearby airports, roads, and entertainment venues, can help real estate agents provide accurate information to buyers and sellers.

Noise pollution not only affects property values but also has detrimental effects on health, contributing to sleep problems, chronic annoyance, and even heart disease. Therefore, it is essential for real estate agents to be transparent about noise levels when providing valuations and for buyers to be aware of the potential impact of noise on their daily lives and future resale value.

Pollution from traffic emissions

Traffic emissions are a significant source of pollution, which can have a detrimental impact on real estate values. Noise pollution from busy roads and highways can result in decreased property prices, as buyers often associate noisy areas with reduced desirability, liveability, and safety. The impact on real estate prices can range from a minor to a significant decrease, depending on the noise level and the sensitivity of the local market.

The effects of traffic noise on property values can be influenced by various factors. For instance, the presence of an airport within close proximity can lead to a substantial drop in property prices, with discounts of up to 13.2% observed within a 2-mile radius. Similarly, proximity to railway tracks and highways can result in discounts of 12.3% and 11.3%, respectively. These discounts reflect the inconvenience and noise associated with living near transportation hubs.

The World Health Organization (WHO) has defined noise levels above 65 decibels (dB) as constituting noise pollution, with noise above 75 dB being harmful and above 120 dB causing pain. Heavy traffic noise can reach up to 85 dB, which is significantly higher than the recommended levels. This constant background noise can negatively impact the quality of life for residents, leading to sleep problems, chronic annoyance, and even contributing to heart disease, according to the European Environment Agency.

In addition to noise pollution, traffic emissions also contribute to air pollution, which can have direct health consequences for residents. Air pollution can affect the health of those living nearby, as well as impact vegetation and soil quality. The deposition of airborne chemicals, soot, and aerosolized droplets can accumulate on the land, affecting animals, crops, and the overall health of the ecosystem.

The impact of traffic emissions on real estate values is a critical consideration for buyers, sellers, and landlords. Buyers seek quiet neighbourhoods, while sellers rely on accurate valuations. Landlords may find that noise pollution reduces the rent they can charge, as tenants may be deterred by the negative impacts on their daily lives. Therefore, it is essential to assess noise pollution levels accurately and communicate their potential impact on property values to all parties involved.

The influence of air pollution on the residential market

Air pollution has a significant impact on health, with around 8.8 million deaths a year attributed to it globally. As awareness of the health risks grows, consumers are becoming more discerning about the air quality in the areas where they choose to buy homes.

In the UK, a joint report by the Royal College of Physicians and the Royal College of Paediatrics and Child Health stated that air pollution causes the premature deaths of up to 40,000 people a year. The World Health Organization (WHO) has estimated the cost of air pollution to the UK economy to be £54 billion a year, or around 3.7% of the national GDP.

The main sources of air pollution in developed countries are traffic emissions and domestic combustion of fossil fuels. Motor vehicles running on petrol or diesel emit a wide variety of pollutants, including carbon monoxide, nitrogen oxides, volatile organic compounds (VOCs), and particulate matter. Electric vehicles are often referred to as generating zero emissions, but they still produce non-exhaust particulate matter at a rate equal to that of internal combustion engines.

The impact of air pollution on property values is becoming an increasingly important consideration for buyers. A report in the Daily Telegraph quoted property agent Henry Pryor as estimating that pollution can reduce a home's price by up to 15% compared to a similar property in a less polluted area.

Some people are calling for an air pollution rating for each property, which could have a significant impact on housing values. If such a rating were introduced, there is a risk that only the most vulnerable in society would be able to afford housing with the worst ratings.

Public awareness of air pollution is currently low but is beginning to rise. Citizen-funded advertising campaigns in London have highlighted the link between air pollution and health issues, with billboards carrying slogans such as 'These houses cost an arm, a leg, and a lung' and 'Location, location, lung disease'.

Various government and private websites provide a new level of detail for homebuyers to consider when assessing the air quality of a particular area. The UK's National Atmospheric Emissions Inventory (NAEI) has created an interactive map that gives consumers an indication of the impact on air quality from a wide range of the most common pollutants.

Real estate agents need to be transparent about every aspect of a property, including noise pollution, which can also affect property values. A Polish study found that high levels of background noise negatively impacted apartment prices, with railway noise causing the biggest decrease in value. Aviation noise was the second-biggest problem, followed by road noise.

While there is no cost-effective way to avoid air pollution with regards to real estate, there are measures that can be taken to mitigate its effects. These include sealing up homes and installing air filtration systems, but these options tend to be very expensive.

If the source of air pollution is close to the real estate, owners can ask local governments to restrict the types of pollution being emitted or sue the polluter in the hopes that a court will compensate them. If the source of pollution is not close, the options for real estate owners become more limited, and the focus should be on persuading elected officials to enact tougher laws on pollution that affect the region as a whole.

The cost of air pollution to the economy

Air pollution has a significant impact on the economy, with the World Health Organization (WHO) estimating an annual cost to the UK economy of £54 billion, or around 3.7% of the national GDP. In some European countries, the cost is even higher; in Bulgaria, for example, it is estimated to be equivalent to 29.5% of GDP.

The primary sources of air pollution have historically been high levels of smoke and sulphur dioxide from the combustion of fossil fuels for domestic and industrial use. However, the biggest threat to clean air today comes from traffic emissions, with motor vehicles running on petrol or diesel emitting a wide range of pollutants, including carbon monoxide, nitrogen oxides, volatile organic compounds (VOCs), and particulate matter. Electric vehicles are often touted as a solution, but they still produce non-exhaust particulate matter at a rate similar to that of internal combustion engines.

The impact of air pollution is not limited to the outdoors. The growing popularity of wood-burning heaters in homes increases pollution levels in houses and their immediate vicinity, with domestic wood-burners producing 51% of all PM2.5 emitted directly into the air in 2017, according to an EU report. Poor air quality in the workplace also affects cognitive functioning, with buildings that minimise VOCs and enhance ventilation enabling better cognitive functioning than those with higher levels of indoor pollutants and lower fresh-air intake.

The cost of air pollution extends beyond just the economic impact. Globally, around 8.8 million deaths per year are attributed to air pollution, mostly in developing countries. In the UK, a joint report by the Royal College of Physicians and the Royal College of Paediatrics and Child Health stated that air pollution causes the premature deaths of up to 40,000 people annually, with an estimated 29,000 caused by particulate matter and 23,000 by nitrogen oxides.

Air pollution also has a significant impact on real estate values. Property agent Henry Pryor estimates that pollution can reduce a home's price by up to 15% compared to a similar property in a less polluted area. The presence of an airport, for example, can cause properties in close proximity to sell for up to 20% less than the average of homes in the next concentric circle. Similarly, sellers within a 2-mile radius of an airport will typically discount prices by 13.2%, and discounts are also offered for proximity to railway tracks (12.3%) and highways (11.3%).

Noise pollution, a significant component of air pollution, also plays a role in reducing property values. A Polish study found that high levels of background noise negatively impacted apartment prices, with railway noise causing a 1.79% decrease in value for every 1dB increase above a 55dB level, aviation noise causing a 0.59% decrease for every decibel increase, and road noise causing a 0.12% drop.
