The need to abate pollution is recognized under the International Covenant on Economic, Social and Cultural Rights (ICESCR) which enshrines the right of every person to the enjoyment of the highest attainable standard of physical and mental health. In order to realize this right, the Covenant urges states to take relevant measures including those necessary for the improvement of all aspects of environmental and industrial hygiene. It has been argued that these provisions of the ICESCR recognise the right of every person to be free from all forms of pollution including air pollution.
In addition, the United Nations Framework Convention on Climate Change (UNFCCC) is an international legal instrument that seeks to confront climate change by stabilizing greenhouse gas concentrations at a level that would prevent dangerous anthropogenic (human induced) interference with the climate system. Achieving the objectives of the UNFCCC is also vital in abating air pollution. It has been correctly argued that air quality and climate change are interconnected because the chemical substances that lead to a degradation in air quality are normally co-emitted with greenhouse gases. Therefore, changes in one inevitably cause changes in the other.
As a result, efforts to combat climate change by avoiding or limiting greenhouse gas emissions are also important in tackling air pollution. It is therefore necessary to achieve the objectives of the UNFCCC by combating climate change in order to simultaneously abate air pollution. WHO Global Air Quality Guidelines seek to enhance the global response to air pollution. According to the Guidelines, clean air is fundamental to health. The Guidelines offer quantitative health-based recommendations for air quality management, expressed as long- or short-term concentrations for a number of key air pollutants.
According to WHO, exceedance of the air quality guideline levels is associated with major risks to public health. Though the Guidelines are not legally binding standards; they do provide WHO Member States with an evidence-informed tool that can shape legislation and policy on air pollution. Ultimately, the goal of the WHO Guidelines is to provide guidance to help reduce levels of air pollutants in order to decrease the enormous health burden resulting from exposure to air pollution worldwide. WHO sets out several measures that are necessary for implementation of the Guidelines including the existence and operation of air pollution monitoring systems; public access to air quality data; legally binding, globally harmonized air quality standards; and air quality management systems.
Implementing the WHO Guidelines is therefore necessary to abate air pollution. According to the Guidelines, abatement refers to the reduction or elimination of pollution, which involves either legislative measures or technological procedures, or both. Further, the United Nations General Assembly (UNGA) has recognized the human right to a clean, healthy and sustainable environment61. According to the United Nations, this right includes the right to clean air.
According to the United Nations, the impact of climate change, the unsustainable management and use of natural resources, the pollution of air, land and water, the unsound management of chemicals and waste, the resulting loss of biodiversity and the decline in services provided by ecosystems interfere with the enjoyment of a clean, healthy and sustainable environment and that environmental damage has negative implications, both direct and indirect, for the effective enjoyment of all human rights.
It has been argued that the UNGA Resolution is a watershed moment in the fight against the triple planetary crises of climate change, biodiversity loss and pollution. It has also been pointed out that upholding the right to a clean, healthy, and sustainable environment is vital in protecting the planet and its people from air pollution among other environmental problems. It is thus imperative to safeguard the human right to a clean, healthy, and sustainable environment as part of the measures towards abating air pollution.
