Turning green GDP on its head

Ma Zhong

Readinch

Calculating green GDP is a complex business which few can agree upon, according to renowned economist Ma Zhong. More practical, he argues, is a system that makes organisations and businesses account for environmental costs during production – before, not after environmental losses occur.

China’s prolific economic growth has come at considerable cost to her environment. More than 80% of the country’s rivers are so heavily polluted they no longer support fish, and research institutions, including the World Bank, are busily attempting to place an economic value on the damage which some claim runs into tens or even hundreds of billions of yuan (1 billion yuan = US $125 million).

Some damage estimates have, without doubt, come as a surprise, but their underlying message – that China’s environmental crisis is serious – has not been denied and interest in green GDP accounting – a system to calculate GDP that subtracts a value for environmental cost – is on the rise.

For environmentalists the benefits of green GDP are obvious: a potentially powerful mechanism for environmental protection. Current accounting methods, they say, treat the environment as expendable whereas green GDP, if adopted, could begin to reverse the effects of environmental degradation.

Economists and statisticians – to whom GDP figures are bread and butter – see the significance of green GDP more from a scientific perspective: the accuracy of data, to them, is paramount. Together, however, their mixed interests have led to growing calls for the implementation of green GDP accounting.

The alliance, however, has yet to resolve basic issues that prevent the concept of green GDP from becoming reality. Specific concerns over how exactly to calculate environmental losses have yet to be resolved.

Time is one critical factor in the equation since environmental degradation is often a slow process that takes places over a long period – decades, centuries or even longer. Unusually severe dust storms that hit areas of northern China in April were, for example, were caused by changes in agricultural practices over the course of many years. Lung cancer can also be caused by extended periods of exposure to polluted air. Damages, therefore, would need to be spread over a number of years in the same way that an accountant writes-off an asset. But over how many years and at what value?

Estimations of environmental loss in terms of hard currency can also vary considerably because, unlike the conventional marketplace, there is no clear relationship between supply and demand of public resources over which there is little ownership. At present, calculating the value of environmental loss with any degree of accuracy is almost impossible.

Disagreements over methodology suggest that the hope of realising the goal of environmental protection through establishing green GDP is unworkable. However, this should not become a justification for abandoning green GDP altogether.

Opportunities, for example, do exist to use conventional GDP figures as a means to analyse, evaluate and improve upon the cleanliness of economic growth. Recent work by the national statistical bureau found that richer, eastern provinces – where growth has been fuelled by heavy industry – have begun to restructure their economies in favour of cleaner, service industries. Poorer western provinces, however, are still in the process of heavy industrialisation and pollution levels there are set to rise.

The current Five-Year Plan – the 11th, which runs from 2006–2011 – also shows encouraging signs. Environmental targets, many of which have been missed during the past – emissions of sulphur dioxide exceeded the target set in the 10th Five Year Plan (2001-2005) by almost 40% - have now been integrated with economic targets. The hope is that China’s success in achieving targets for economic growth over the past twenty years can now help with environmental protection, in particular energy efficiency. One of these newly conceived indicators reduces, by 20%, the amount of energy consumed to generate one unit of GDP. Another reduces the amount of pollutant discharge from work units in relation to GDP by 10%.

In this way at least some environmental costs are accounted for during production - before, not after environmental losses occur – and will naturally make GDP calculations much greener without the need to assess environmental loss, which is far less easy. If government, manufacturers and ordinary citizens continue to recognise environmental protection as part of the everyday costs of economic production this paves the way for setting more ambitious targets and increasing environmental protection.

绿色GDP 和其它的颜色

这篇文章建议通过极大考虑环境的因素来完善国家的统计数据。 用类比的方法来说,让公司和企业给出一份他们利用资源,比如水,的报告,是不是一个好的主意和做法?

Green GDP - and other colours

This article helpfully suggests ways of improving national statistics to take greater account of environmental factors. Would it also be a good idea for companies and enterprises to report on their use of resources, like water?


分享经验和成功的做法

绿色GDP这一概念在中国很流行,但大众对它的实际意思并不是很清楚。这一文章简述了这个概念,使之通俗易懂。很感谢“中外对话”提供了这样的一个平台。同时,也很感谢如果有其他的读者能给我提供一些关于中国政府已经和正在做的绿色GDP的努力?英国政府对绿色GDP的态度是什么?在中英两国之间,在绿色GDP方面有没有可以相互借鉴的经验和好的做法?Syleaf

sharing lessons and best practices

The concept of Green GDP is popular in China but the real meaning is not very clear to general public. This article makes it easy to understand by simplfying the theory.

Thanks to Chinadialogue for providing this platform. Grateful if other readers could share ideas with me about what Chinese government has done and is going to do? What is the British Government's attitude toward Green GDP? And are there any lessons or best practices which can be shared between the UK and China?

Sylea 你好,

如果你想了解更多有关中国绿色GDP的情况,“中外对话”建议你阅读另外一篇在本网站上的文章:胡鞍钢先生的《中国的绿色发展之路》。

Another green GDP article on CD site

Hello Syleaf,

If you want to know more about green GDP in China, we suggest you to read another article on chinadialogue site: Green development: the inevitable choice for China by Angang Hu
