In order to abate air pollution, it is necessary to realize the right to a Clean, Healthy, and Sustainable environment. This right encompasses various elements including clean and balanced ecosystems, clean air, rich biodiversity and a stable climate. A safe, clean, healthy and sustainable environment is considered to be integral to the full enjoyment of a wide range of human rights, including the rights to life, health, food, water and sanitation.
The right to a Clean, Healthy and Sustainable Environment is an essential human right that has been equated to the right to life. The importance of this right has been upheld by UNGA which recognized the human right to a clean, healthy and sustainable environment. It has been argued that realization of the right to a Clean, Healthy, and Sustainable environment can aid in tackling environmental challenges such as pollution, climate change, and unsustainable management of natural resources.
It is therefore necessary to realize the right to a Clean, Healthy, and Sustainable Environment in order to abate air pollution alongside other environmental problems. In addition, there is need to strengthen air quality laws and regulations including through monitoring. Air quality across the globe continues to deteriorate due to air pollution threatening human health and contributing to climate change and biodiversity loss.
In addition, it has been argued that air quality monitoring and transparent access to data is critical for humanity since it helps us understand how air pollution impacts people, places and planet. Through monitoring, it is possible to identify air pollution hotspots and take targeted action to protect and improve human and environmental well-being. However, it has been noted that air quality monitoring is yet to be fully embraced in developing countries meaning that people may be disproportionately impacted by air pollution in such countries.
It is therefore necessary to enhance air quality monitoring by implementing air quality laws and investing in technology and infrastructure to improve data reliability. Investing in technology will enable government agencies to achieve real time air pollution monitoring which can go a long way in ensuing that pollutants are kept within acceptable levels as defined by the WHO standards.
Further, it is imperative to fully operationalize and enhance the enforcement of laws and regulations on air pollution. For example, in Kenya, it has been argued that it is vital to fully operationalize the Air Quality Regulations in order to ensure clean and healthy ambient air. In addition, there is need for strict enforcement of compliance with the emission standards for various sources such as mobile sources including motor vehicles and stationary sources such industries as stipulated in the Air Quality Regulations and EMCA.
One of the key ways that can be used to achieve this goal is effective enforcement of the polluter pays principle. According to this principle, the costs of pollution should be borne by the polluter. The aim of this principle is to distribute the costs of pollution from governments to organisations and people that engage in acts of pollution.
Under the Rio Declaration on Environment and Development, national authorities should endeavour to promote the internalization of environmental costs and the use of economic instruments, taking into account the approach that the polluter should, in principle, bear the cost of pollution, with due regard to the public interest and without distorting international trade and investment.
Further, under EMCA, the cost of cleaning up any element of the environment damaged by pollution, compensating victims of pollution, cost of beneficial uses lost as a result of an act of pollution and other costs that are connected with or incidental to the foregoing, is to be paid or borne by the person convicted of pollution under this Act or any other applicable law. It is therefore necessary to implement this principle in order to ensure that organizations and persons found liable of air pollution alongside other forms of pollution bear the costs of such pollution.
It has been argued that making violators bear the cost of environmental restoration will go a long way in not only guaranteeing the right to clean environment but also in achieving Sustainable Development. Courts also have a role to play in abating air pollution at all levels. It has been pointed out that courts provide a platform for realizing access to justice which is key in enforcing human rights including the right to a Clean, Healthy, and Sustainable environment.
For example, in Kenya, the Constitution grants jurisdiction to courts to enforce environmental rights through measures such as orders to prevent, stop or discontinue any act or omission that is harmful to the environment; orders to compel any public officer to take measures to prevent or discontinue any act or omission that is harmful to the environment; orders to provide compensation for any victim of a violation of the right to a clean and healthy environment among others.
There is need for courts to promote the realization of the right to a clean, healthy and sustainable environment by enhancing the principles of Sustainable Development and developing sound jurisprudence in environmental matters including cases concerning air pollution. Further, it is necessary to enhance access to justice including access to courts in order to allow victims of air pollution among other environmental malpractices to realize environmental justice.
Finally, it is of utmost importance to combat climate change. It has been noted that air quality and climate change are interconnected since 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.
According to the World Bank, air pollution and climate change are two sides of the same coin, but they are typically addressed separately. It asserts that they should be tackled jointly, with a focus on protecting peoples’ health particularly in low and middle-income countries in order to strengthen human capital and reduce poverty.
Therefore, efforts to reduce greenhouse gas emissions provide dual benefits: of better air quality and improved health in localities and the global benefit of mitigating climate change. It is therefore crucial to confront climate change in order to simultaneously abate air pollution.
