Abstract: The purpose of this study is to analyze whether education has a role in energy use in society using the
Environmental Kuznets Curve (EKC) hypothesis during the period 1972-2016 in Indonesia. The paper applied the
Autoregressive Distrubuted Lag (ARDL) Bound Test approach to identify co-integration relationships among variables in
the model. The results confirmed the evidence that education initially increased CO2 emmisions and at some point
education reduced co2 in the short run but not in the long run. In addition, i also found conclusive evidence to support
the Inverted U-shaped EKC hypothesis of the relationship between GDP per capita and environmental degradation. The
stability test has conducted in estimated model and the result indicated that estimated model is stable over time.
Keywords: CO2 Emmision, Environmental Kuznets Curve, Education.
1. INTRODUCTION
Study on the relationship between per capita
income and environmental degradation has been
undertaken by many researchers (Baek & Choi, 2017;
Dinda, 2004; Sehar & Khan, 2013; Shahbaz, Dube,
Ozturk, & Jalil, 2015) who modeled through the
Kuznets Environment Curve hypothesis (EKC) which
was first introduced by Grossman & Krueger (1991) on
the study of potential impact of NAFTA. According to
the Environmental Kuznets Curve hypothesis in the
early stages of economic growth, environmental
degradation and pollution are increasing but at certain
per capita income levels the trend is reversing. This
indicates that the environmental impact indicator is an
inverted U-shaped function of per capita income (Stern,
2003). Increased environmental degradation resulting
from income inequality and then declines in line with
development outcomes.
The environmental indicators in EKC are modeled
on the logarithmic quadratic revenue function on
environmental hazard emissions although many
researchers add new variables in the model
specification to improve estimation results such as
urbanization and income inequality ( Bond & Farzin,
2004; Shahbaz et al., 2015). Not only economic
indicators are used but human capital indicators are
also considered as environmental quality is also
determined from the quality of human resources.
Education is one of the most widely used human
capital indicators despite the issue of endogenity

between education and income (Gangadharan &
Rebecca, 2001). However, the limited number of
studies that take account of education cannot find
consistent evidence (Balaguer & Cantavella, 2018).
Research conducted by Bond & Farzin (2004) found
out that education has a negative impact on
environmental quality. While some studies have found
no effect of education on pollution production
(Williamson, 2017).
This study focuses on the importance of education
on environmental degradation shown by CO2
emissions. This is based on the assumption that the
energy used in the community is determined by the
quality of the citizen. As the level of education of citizen
increases, it is believed to increase the level of
environmental awareness through individual
performance and policy makers so that the harmful
emissions can be reduced. In addition, a high level of
education can create more sophisticated and better
technology in production output and emissions
(Williamson, 2017). Therefore, based on the
Environmental Kuznets Curve hypothesis it is believed
that educational enhancement, ceteris paribus, will shift
the downward curve due to a decrease in pollution. The
purpose of this study is to analyze the role of education
on environmental quality in Indonesia in 1972-2016.
Other variables used are trade openness, population
and industrial value added. The research method used
is Autoregressive Distributed Lag (ARDL) Bound
Testing which can estimate short and long term
relationship in estimated model. This research is
structured as follows: in section 2 encompassing the
literature review, section 3 is a research methodology
and in sections 4 and 5 includes results and
conclusions.
