The Welsh Government has published a White Paper setting out plans for a Clean Air (Wales) Bill, which seeks to protect the health of the nation and defend ecosystems from pollutants in atmosphere, in law.
Consultation on the White Paper has also been launched.
Lesley Griffiths, the Minister for Environment, Energy and Rural Affairs, commented: “Breathing clean air and having access to a healthy environment is a right, not a privilege.
“We must take decisive and lasting action now to enable our future generations to lead healthy lives.
“Welsh Government’s number one priority remains keeping our communities safe and supporting families and businesses through the COVID-19 pandemic.
“But just like COVID, air pollution disproportionately impacts the most disadvantaged and vulnerable in our society.
“We know from the report published today that the situation is not straightforward.
“I welcome views from the public, academics, charities and businesses alike, to help us paint a clear picture of how we will improve our air quality and collaboratively build our path to a greener and healthier Wales.“
Poor air quality is estimated to contribute to a reduced life expectancy and death, tallying an equivalent of between 1,000 and 1,400 mortalities in Wales each year.
The World Health Organisation (WHO) states air pollution as the single largest environmental health risk, globally.
A report on the pandemic’s impact on air quality from March – October 2020, which investigates the science of anecdotal claims that lockdown led to cleaner air enjoyed in towns and cities throughout Wales, has also been published.
The report paints a complicated picture: the first two months of lockdown saw significant decreases in some pollutant levels, consistent with reduced traffic.
However, other pollutant levels reportedly increased.
While less cars on the road meant a decrease of 36% and 49% in nitrogen dioxide and nitrogen oxides concentrations, respectively, at Wales’ roadsides between March and May, a change of weather pattern brought polluting fine particulate matter (PM2.5) from continental Europe.
Continued analysis of the longer term changes in air pollution due to lockdown measures will continue as data emerges.
In Wales, poor air quality is reported to have an especially pronounced impact on the health of the most vulnerable – such as the very young or very old, or people with cardiovascular diseases and respiratory conditions like asthma and Chronic Obstructive Pulmonary Disease.
Air pollution is also reported to have a profound negative impact on the natural world, with more nitrogen and pollutants in the atmosphere being a leading factor in the threat of extinction of Wales’ plants and animals.
The Welsh Government is also consulting on approaches to reduce emissions from domestic burning of solid fuels, and is proposing similar restrictions to those passed by UK Government for England.
The restrictions consider the types of fuel used in the home, and would ban the sale of house coal and restrict the sales of wet wood.
These are two of the most polluting forms of solid fuel used in households in Wales.
A spokesperson for the Welsh Government commented: “This is not an attempt to ban the use of wood as a fuel, or to ban the use of wood-burning stoves.
“We do, however, aim to inform the public of the hazards posed from fine particulate matter and other air pollution released from burning in any form, and the harm that it does to the health and well-being of the people of Wales.”
More information about the ‘Reducing emissions from domestic burning of solid fuels’, which runs until 7 April, is available on the Welsh Government website.
