Environmental pollution is a pressing issue that has been linked to economic growth and development. While economic growth, often measured by Gross Domestic Product (GDP), has lifted many out of poverty, it has also been associated with a decline in environmental quality. This has led to a debate on whether environmental pollution is adequately accounted for in GDP calculations and if there are better ways to measure economic growth that takes into account the environmental impacts.

Environmental pollution is not accounted for in GDP
GDP is calculated by summing up specific components, typically consumption, investment, government spending, and net exports. However, it does not include the costs and impacts of environmental pollution, which can have far-reaching consequences. For instance, the World Bank reported that approximately 87% of the global population lived in areas with air pollution levels exceeding the World Health Organization's safety standards in 2013. This resulted in a 30% increase in premature mortality, from 2.2 million to 2.9 million deaths annually between 1990 and 2013.
The exclusion of environmental pollution from GDP calculations can lead to poor decision-making and policy choices. It fails to capture the true costs of economic activities, particularly those that are highly polluting. For example, firms that rely heavily on fossil fuels may not want their value to be net of the pollution damage they cause. As a result, the existing accounts mismeasure the net value of their production activities.
To address this issue, the concept of green accounting has emerged. Green accounting aims to incorporate the value of environmental pollution damages that fall outside the scope of traditional GDP calculations. It involves considering factors such as the chemistry of pollutants, who or what is exposed to them, and the resulting health risks. While green accounting faces empirical challenges, advancements in environmental modeling methods have allowed for more rigorous estimates of pollution damage.
Furthermore, the relationship between economic growth and environmental pollution is complex. While economic growth can lead to increased pollution emissions, this relationship is not always linear. In some cases, economic growth may even inhibit pollution emissions, as seen in Norway's simultaneous economic growth and significant reductions in air pollution levels. Nevertheless, the overall trend suggests that environmental costs are often a byproduct of economic progress, as demonstrated by China's dramatic decline in air quality alongside its economic success.

Green accounting works to address this
Environmental pollution is not accounted for in GDP calculations. GDP, or gross domestic product, is a sum of a nation's consumption, investment, government spending, and net exports. However, it does not include the environmental costs associated with economic activities, such as the use of pollution-intensive fossil fuels or the emission of pollutants into the environment.
Green accounting, also known as environmental accounting or sustainability accounting, is a type of accounting that aims to address this issue by incorporating environmental costs into the financial results of operations. It helps businesses understand the potential trade-offs between traditional economic goals and environmental goals, and it provides valuable information for policy analysis. By considering the environmental impact of their operations, companies can make more informed decisions about their practices and investments to protect the natural environment.
One of the key focuses of green accounting is the depletion of scarce natural resources and the measurement of environmental degradation costs. It uses the System of Environmental Economic Accounting (SEEA) to quantify these costs and prevent further depletion. Green accounting also promotes sustainability by encouraging green public procurement and green research and development. Additionally, it includes penalties for polluters and incentives such as tax breaks to motivate companies to reduce their negative impact on the environment.
The benefits of green accounting extend beyond individual businesses. At the national and international levels, sustainability accounting can be utilized through Environmental National Accounting (ENA), which takes into account the ecological and economic impacts on an entire country. This type of accounting is particularly relevant in today's globalized world, where environmental issues like water and air pollution can easily cross borders and affect neighbouring countries.
While green accounting is a step towards a more sustainable future, it is important to recognize that it is not without its challenges. One obstacle is the historical and empirical nature of data collection, as well as the resistance to change from the status quo. Additionally, depletion may already be factored into accounting for extraction industries, and the accounting for externalities may be arbitrary. Despite these challenges, green accounting is a crucial tool in the effort to slow down climate change and promote environmental responsibility among businesses.

Pollution damage measurements have matured since 1973
Environmental pollution is not accounted for in GDP calculations. However, green accounting attempts to address this by including the value of environmental pollution damages. While it is challenging to measure the impact of pollution accurately, pollution damage measurements have advanced since the 1970s.
For instance, to understand the impacts of pollution emitted by a power plant, it is essential to consider factors such as the dispersion of pollutants, their chemical transformations, who or what is exposed, and the resulting health risks. By addressing these complexities, modern environmental modelling methods provide more rigorous estimates of pollution damage.
The recognition of pollution damage as an economic concern has evolved since the 1970s. Initially, pollution was primarily viewed as a local issue, with limited understanding of its potential to transcend borders and affect neighbouring countries. However, as globalisation intensified, it became evident that pollution could have far-reaching consequences, impacting regions beyond the polluting source. This realisation prompted a shift in perspective, highlighting the need to address pollution as a global issue.
The measurement of pollution damage has progressed since the 1970s, with the development of more sophisticated tools and methodologies. For example, the US Environmental Protection Agency (EPA) now estimates emissions of ambient air pollutants and their precursors, utilising monitored readings and engineering calculations. This enables the tracking of emissions data from various pollution sources, informing policy decisions and interventions.
While pollution damage measurements have advanced, challenges remain. Empirical obstacles and resistance to change persist, hindering the full integration of environmental accounts into economic assessments. Nonetheless, the progress made since the 1970s provides a foundation for continued improvement in addressing the complex issue of pollution damage.

Economic growth increases environmental pollution emissions
Economic growth and environmental pollution emissions have a complex relationship. While economic growth can lead to increased pollution emissions in the short term, this relationship may not hold true over the long term. Several factors influence this dynamic, and it is essential to recognize that not all forms of economic growth harm the environment.
In the early stages of economic growth, particularly in developing countries, there is often a surge in industrial activity and energy consumption, which can result in higher pollution emissions. This is evident in China's experience, where rapid economic expansion has severely damaged its ecological environment. The country's economic development has outpaced the carrying capacity of its environment, leading to issues such as air and water pollution that extend beyond its borders.
However, as economies mature and transition to post-industrial phases, the relationship between economic growth and pollution emissions can change. For instance, the UK and the US have witnessed reductions in CO2 emissions since 1980, despite economic growth. This improvement can be attributed to factors such as higher incomes enabling investments in cleaner technologies, improved fuel efficiency, and policy interventions to curb pollution.
It is worth noting that economic growth can also create long-term waste and toxins, such as the accumulation of non-degradable plastics in the environment. Additionally, increased consumption of non-renewable resources and the potential loss of environmental habitats are further consequences of economic expansion. Nevertheless, economic growth driven by technological advancements can lead to higher output with reduced pollution, as seen in Norway's economic growth paired with significant pollution reductions.
To address the challenges posed by economic growth on the environment, green accounting has emerged as a promising approach. It aims to incorporate the value of environmental pollution damages into economic performance measurements, providing a more comprehensive understanding of the true costs and benefits of economic activities. While there are empirical obstacles to implementing green accounting, advancements in environmental modeling methods have enabled more rigorous estimates of pollution damages.
In conclusion, while economic growth may increase environmental pollution emissions in the short term, particularly in developing countries, this relationship is not linear or inevitable. The transition to a post-industrial economy, technological advancements, policy interventions, and the ability to devote resources to environmental protection can help decouple economic growth from pollution emissions. Recognizing the complex interplay between economic growth and pollution is crucial for developing sustainable policies that balance economic development and environmental preservation.

Some countries exhibit a tradeoff between economic growth and environmental quality
The relationship between economic growth and environmental quality is complex and multifaceted. While some countries may exhibit a trade-off between economic growth and environmental quality, it is essential to recognize that this relationship is not linear and can vary depending on a country's level of development and other factors.
In less developed or poorer countries, the focus is often on meeting immediate material needs and addressing poverty, which can lead to environmental degradation. This is known as poverty-induced environmental degradation, where the trade-off between economic performance and environmental protection is more apparent. For example, less developed countries may be less willing or able to invest in long-term environmental protection measures, such as pollution control technology, as they prioritize short-term economic gains.
On the other hand, in richer or more developed countries, the relationship between economic growth and environmental quality can be reversed. As countries become more economically advanced, people can afford more efficient and environmentally friendly production methods, resulting in a cleaner environment. This is known as the Environmental Kuznets Curve (EKC), which suggests that as countries reach a certain level of economic development, the association between economic growth and environmental quality improves.
However, it is important to note that the EKC does not apply universally. Some countries, like China, have experienced significant economic growth alongside dramatic declines in air quality. China's economic success has contributed to increased pollution levels beyond its borders, affecting neighbouring countries such as South Korea. This highlights the global nature of environmental issues and the impact of economic decisions in one country on others.
Additionally, the idea of a trade-off between economic growth and environmental protection can be manipulated. For instance, it is argued that investing in environmental clean-up can stimulate economic growth by attracting businesses, residents, and tourists. A clean environment also reduces healthcare costs by lowering illness rates. Furthermore, environmental regulations can motivate firms to adopt new technologies, potentially increasing economic growth in the long run.
While some countries may exhibit a trade-off between economic growth and environmental quality, it is not an inevitable outcome. The implementation of environmental regulations, responsible consumption practices, and investments in sustainable infrastructure can help countries achieve economic development while maintaining environmental integrity.

Frequently asked questions
No, environmental pollution is not accounted for in GDP.
Indices that focus exclusively on market production, such as GDP, are widely recognised to be incomplete. Environmental pollution is a non-market service.
Green accounting aims to include the value of environmental pollution damages that extend into non-market impacts. For example, if we are looking at the impacts of pollution emitted by a power plant, we need to know where that pollution goes, what it turns into, the chemistry involved, who or what is exposed to it, and the value of the impacts.
