The Kaya Identity: The Case of Turkey

The Kaya Identity expresses carbon dioxide emission levels as a product of population, Gross Domestic Product per capita (personal wealth), energy intensity (energy per GDP) and carbon intensity (CO2 emissions per energy consumed). Developed by Yoichi Kaya, its mathematical notation is F = P(G/P)(E/G)(F/E) where F is carbon dioxide emissions, P is population, G is GDP, and E is energy consumption.

It can be calculated not only for global emissions, and hence for modeling, but also for individual economies. Although it has been viewed as tautological by some(1), the IPCC report also uses it. “The Kaya multiplicative identity. . . underlies the analysis of the emissions scenario literature.”(2)

The World Bank data make it easy to calculate the index. The chart below, produced using the Bank data, shows clearly the steep increase in Turkey’s carbon footprint. If the present trend continues, the carbon emissions are likely to increase for the foreseeable future.


It is obvious that population plays an important role in the size of an economy, and the bigger an economy gets, the more it will need and consume energy. Liberal economics primarily focuses on economic growth, which, regardless of how incomes are distributed or to what extent growth is translated into development, is deemed desirable for raising standards of living. One question at this point is how far we can go without depleting the world’s resources. Another question can be raised regarding climate change and global warming. However, in a capitalist, and therefore, consumption-based economy where firms produce commodities in a competitive (and also in oligopolistic) conditions it is difficult to imagine producers coming up with alternative (environmentally friendly, so-called sustainable) policies and technologies unless they are forced to do so through government regulation.

Energy intensity can be reduced by developing technology to increase efficiency in energy use. Furthermore, development of renewable energy sources (wind, solar and other forms of energy) should reduce carbon emissions, but again,  this is a matter of the extent to which governments can enact and enforce regulations to reduce harmful emissions. Otherwise, firms will carry on their business as usual, externalizing their costs regardless of any ethical considerations this kind of behavior might imply. Recent history has countless examples of such blatant violation of ethics and of regulation no matter how permissive or restrictive those regulations might have been.

In the face of global warming, which is well-documented now, it is imperative that governments, including those of Turkey, tackle these issues urgently otherwise humanity moves headlong toward its own demise.  As Christine Lagarde, the head of the IMF, recently put it, “If we collectively chicken out of this, we’ll all turn into chickens and we’ll all be fried, grilled, toasted and roasted.”(3)

Obsessed with Political Stability

The turbulent 1970s inflicted a lot of pain and suffering on Turkish society. Sharpening class struggle, internal strife and terrorism along with frequently formed coalition governments in the context of economic bottlenecks that were associated with import-substituting industrialization prompted the coup d’état of 1980. The military junta formed by the leaders of the coup curtailed civil rights, repressed wages, persecuted the left and eventually drafted a constitution and made changes in the electoral system. The most important change in the elections were the introduction of 10% nation-wide threshold for the participating parties. The rationale for this was that the previous system allowed too many political parties to enter the parliament, resulting in coalitions that were allegedly a source of instability and ineffectiveness.

One of the arguments put forth by the ruling AKP (the Justice and Development Party) in its election campaigns and in their overall discourse has been to maintain “stability” in the country. For this reason the AKP was never interested in lowering the threshold of 10 percent national vote that eliminates small parties from the parliament. For the same reason, the AKP recently managed to change the regime from a parliamentary one to a presidential one, causing a lot of heated debate, controversy and unrest. The regime change is a relatively new development, and we have yet to see if and to what extent it has contributed to stability, but the election practices have been around for the last few decades, sometimes causing a significant portion of the electorate not being represented in the parliament.

Therefore, a look at the numbers will be useful to assess the argument for “stability.” Granted that this is not an in-depth analysis of Turkish politics, even a cursory examination of it can reveal a lot and give us some insight.

Since the proclamation of the Republic in 1923, 57 governments were formed until 2002 when the AKP won the elections and came to power. Being able to draw a significant amount of support from its voters, the AKP has managed to win consecutive elections, and at the moment it is the ruling party. Since 2002, the AKP, having won several local and parliamentary elections, and including some government shuffling along the way, has formed 8 governments.


Year per Cabinet: The AKP and Others










In other words,  this means 57 governments in the 79 years between 1923 and 2002, and 8 governments between 2002 and 2017. Put differently, a new government was formed every 1.39 years during the former period, and a new one every 1.88 years during the latter period.

Year per Cabinet: Multi-party Period










If we exclude the single-party period (1923-46), Turkey has had 43 governments in the following 56 years (1946-2002), which translates into an average duration of 1.39 years for all governments, 1.30 years for non-AKP governments, 1.88 years for the AKP.

This crude calculation shows that the AKP governments have been able to stay in power somewhat longer than all the previous governments, regardless of all other factors. However, the difference does not seem to be all that impressive, considering that a life of 1.88 years per government still falls short of the prescribed period of four years between elections. Also, considering the increasing terrorism and tension regarding the Kurdish issue, not to mention the economic dire straits that the country is facing at the moment, the question is whether the AKP can be regarded as any more successful in tackling the problems it faces, or its performance and stay in power as an achievement of stability.
