Modern society is full of sources of pollution, particularly in places that rely on the burning of fossil fuels. Successful attempts to reduce the amount of pollution stemming from car travel in London have led to gas boilers overtaking motor vehicles as the main source of polluting nitrous oxides, suggesting their usage may also need to be moderated.
What Kind of Pollution Is Being Released?
The pollution in question is formed of nitrous oxides or NOx, which can trigger airway inflammation, aggravate allergies, make you more susceptible to respiratory infection, contaminate soil and damage biodiversity. Its impact can be magnified when it interacts with other common sources of air pollution to create ozone, and it is particularly dangerous to people with existing heart or breathing conditions.
Research specifically looked at NOx pollution levels in the vicinity of the BT Tower in London in the period from 2021 to 2023. It found that as much as 72% of NOx emissions were associated specifically with gas boilers.
Why Is There Less Motor Vehicle Pollution?
In recent years, many attempts have been made to reduce the NOx emissions resulting from motor vehicle use. This ranges from encouraging car manufacturers to produce more greener vehicles to making public transport more attractive to travellers. In London specifically, the London Low Emission Zone and Ultra Low Emission Zone, or ULEZ, are likely significant contributors to the overall drop in pollution.
How Can We Decrease the Pollution from Gas Boilers?
To reduce pollution from gas boilers, the government has a policy of ensuring new houses are built with air pumps as an alternative source of hot water. It also encourages people replacing their current gas boiler to turn to cleaner alternatives, such as the air source heat pumps Worcester available at gsmlimited.com/services/air-source-heat-pumps/worcester , with the hope that all gas boilers can be phased out by 2035.
There are many reasons that attempts are being made to replace gas boilers with cleaner alternatives, from sustainability to cost. This recent research also suggests that replacing gas boilers may be the best thing for air quality and human health.
