Abstract: - This research aims to 1) study the components of the guidelines for reducing environmental impact in
the industrial sector of the Eastern Region of Thailand and 2) develop a structural equation model for the guidelines
for reducing environmental impact in the Eastern Region industrial sector of Thailand. The research sample for this
study comprises 500 entrepreneurs or managers in the industrial sector in the Eastern Region of Thailand. The
quantitative research uses a questionnaire as a research instrument. Statistical analysis used for data analysis
includes structural equation analysis. The results of the research model developed show that the assumed model is
in line with the empirical data with p-value = 0.091, CMIN/DF = 1.272, GFI = 0.980, and RMSEA = 0.023, which
meet the research assessment criteria. The analysis results based on the research hypotheses indicate that 1) Legal
components have a direct influence on the consultant components, 2) Legal components have a direct influence on
the community components, 3) Consultant components have a direct influence on the resource components, and 4)
Resource components have a direct influence on the community components. The result found that the component
related to environmental consultants directly influences the resource component with the highest Standardized
Regression Weight of 0.88. This result indicates that consulting companies must carry out environmental impact
reporting processes according to the legal requirements to produce transparent evaluations, resulting in increased
community acceptance of the information presented in the reports.

1 Introduction
Outdoor air pollution is a major environmental health
problem affecting everyone in low-, middle-, and
high-income countries. Ambient (outdoor) air
pollution, prevalent in urban and rural areas, was
estimated to cause 4.2 million premature deaths
annually in 2019. These fatalities result from
exposure to delicate particulate matter, leading to
cardiovascular and respiratory disease, as well as
cancers. Based on data from the World Health
Organization (WHO) in 2019, heart attacks and
strokes accounted for approximately 37% of early
deaths related to air pollution outside, while chronic
lung diseases and sudden lung infections were
associated with about 18% and 23% respectively.
Additionally, 11% of such deaths were connected to
cancers in the breathing passages. Individuals
residing in low- and middle-income countries bear a
disproportionate share of the outdoor air pollution
burden, with 89% (of the 4.2 million premature
deaths) occurring in these areas. The most substantial
burden exists within the WHO regions of South-East
Asia and the Western Pacific. The significant
function of air contamination in cardiovascular
sickness and deaths is highlighted in the most recent
burden estimates, [1]. Regulating industrial
operations is necessary in Thailand to prevent the
release of potentially hazardous materials that could
harm the environment. The government has
noticeably taken steps to improve and safeguard the
environment by enacting the "Enhancement and
Conservation of National Environmental Quality Act
of 1992," a fundamental environmental law in
Thailand. This law superseded prior rules protecting

national environmental quality dating back to 1975.
The program addresses various contamination issues,
including water pollution, air pollution, waste
handling, noise, and vibrations. Depending on their
type, an environmental impact review is required for
specific infrastructure, condominiums, and other
initiatives, [2]. The main goal of the EIA process in
Thailand is to ensure decision-makers think about
environmental effects when approving initiatives.
This proactive step is taken to achieve sustainability
targets and prevent ecological problems arising from
significant industrial enterprises. The environmental
impact assessment process necessitates identifying
the potential effects an existing or proposed
undertaking may have on the natural surroundings. It
also involves creating strategies to lessen negative
impacts on the environment, [3].
Even though this process of examining potential
environmental consequences has been used in
Thailand for approximately three and a half decades,
debate continues. Some project leaders consider the
assessment unnecessary, while others try to avoid it.
Government officials overseeing the review face
considerable difficulties, [4]. Furthermore,
environmental impact assessment often lacks robust
backing in many developing countries, including
Thailand, usually due to political and monetary
constraints. Agencies focusing on protecting the
environment frequently find themselves with less
authority compared to organizations prioritizing
economic growth. Two primary factors that
compromise the quality of EIA reports are the
shortage of qualified environmental experts and
constraints in terms of time and funding, [5].
Thailand is no exception to these challenges.
However, there remains a need for continuous
improvement in the EIA process, improvements that
consider the specific project, the geographic context,
and associated factors to encourage the adoption of
effective public participation methodologies. Social
impact assessment (SIA) processes not only assess
the project's impact but can also be used to
understand and ultimately minimize the negative
attitude of neighboring communities, [6].
Industrial establishments are considered vital
drivers of a country's long-term economic growth.
Consequently, the government aims to develop and
strengthen these industries, making them competitive
and capable of supporting the nation's future
prosperity. However, when assessing the
environmental impact of projects or industrial
activities that do not meet the approval criteria set by
the Department of Natural Resources and
Environmental Policy and Planning, it not only poses
risks to the businesses themselves, including issues
related to trustworthiness among stakeholders, but it
can also harm the overall economic growth rate,
particularly in the industrial sector, which may not
meet the predetermined objectives. For this reason,
the researcher is keen to investigate guidelines for
reducing environmental impacts in the industrial
sector of the Eastern Region of Thailand. The aim is
to provide business operators with insights from this
research to inform project development and improve
the environmental impact assessment reports.
1.1 Research Objectives
1) To investigate the components of guidelines for
reducing environmental impacts in the industrial
sector of the Eastern Region of Thailand.
2) To develop a structural equation model for the
guidelines for reducing environmental impacts in the
industrial sector of the Eastern Region of Thailand.
2 Literature Review
2.1 Environmental Impact Assessment
An evaluation of effects on living things and human
welfare, as well as general environmental
circumstances, is called an Environmental Impact
Assessment. It is a methodical process. The goal is to
assess how activities might change things over time.
This includes plans set by law, projects, policies,
standard practices, explanations, and information
sharing. It is important to consider how current
decisions may affect the future and to learn from past
experiences, [7]. As some have noted, [8], evaluating
potential environmental effects helps examine
possible benefits and challenges of a proposed plan
or project. The review aims to understand the impacts
on people, property, and nature. It seeks ways to
lessen negative impacts while increasing positive
outcomes. The goal is to make decisions consistent
with environmental sustainability through a thorough
assessment process.
An important objective of the environmental
evaluation is discovering techniques for limiting
detrimental results while strengthening favorable
impacts. Chief among our concerns is confirming that
evaluations of intended initiatives and tasks align
with the sustainability goals intrinsic to the

assessment procedure. The origins of environmental
effect appraisal can be traced back to the National
Environmental Policy Act of 1969 in the United
States. This concept arose from realizing numerous
publicly supported plans overlooked potential
environmental repercussions during planning and
implementation, inevitably leading to serious
environmental issues. It was initiated because several
government-funded projects failed to consider their
environmental impacts during development and
execution, resulting in substantial environmental
issues. Historically, analysis of cost, benefit, and
environmental protection was the primary focus, but
it was inadequate for safeguarding the environment
within the country. Consequently, public awareness
regarding the environment grew, leading to a
movement that eventually enabled the enforcement of
EIA as a mandatory law starting in January 1970.
EIA became a global foundation for similar
legislation worldwide in the 1970s and 1980s for
developed countries. Countries in Asia that were
developing, such as Indonesia, Taiwan, the
Philippines, Singapore, and Hong Kong, embraced
the concept of EIA within their policies by 1990.
Subsequently, African and Latin American countries
adopted this approach, [9].
In Thailand, the formal beginning of
environmental legislation occurred with the passing
of the National Environmental Quality Advancement
and Preservation Act 1975. This Act established the
National Environmental Board, tasked with specific
responsibilities, including developing policies and
recommendations to boost and safeguard
environmental quality. Another crucial role involved
assessing initiatives that could negatively impact the
natural world. Subsequently, the Act underwent
revisions in 1978, resulting in its second version.
Specifically, regarding the authority and duties of the
National Environmental Commission, these changes
aimed to address vague areas and weaknesses in the
original Act. However, despite these attempts, some
key details remained undefined, leading to challenges
in implementation. Then, the government was
required to tackle these issues; further modifications
were made in 1975 and 1981 to provide more explicit
and inclusive powers and accountabilities to the
National Environmental Board.
Furthermore, in 1981, a new policy was
introduced to evaluate the environmental effects of
specific project categories and scales. Under the
authority of the Ministry of Science, Advancement,
and the Surroundings, this policy took impact on
September 27, 1981. It centered on analyses of
environmental assets and the significance that diverse
projects or deeds could have. In 2002, the
government changed how it handles things. The
Ministry of Science, Technology, and Environment is
now responsible for the National Environmental
Quality Promotion and Conservation Act 1992
(B.E.2535). In April 2018, a revised version of the
National Environmental Quality Promotion and
Conservation Act (Version 2) was enacted, with
multiple subordinate laws issued to establish clear
frameworks and impose penalties for non-
compliance. These legal measures were intended to
compel businesses to consider environmental impacts
more seriously, ensure the creation of accepted
standards, and foster confidence from all
stakeholders in environmental quality and natural
resource conservation. The country's sustainable
development was balanced with maintaining
environmental quality and natural resources, [10].
The following are 4 benefits of EIA that need
attention and can be seen from various aspects, [11]:
1) The benefits of EIA for the government
are more related to policy formation. The government
has higher authority than any party. Therefore, the
use of an EIA is to help prevent more severe
environmental damage and pollution. In addition, the
EIA project benefits the government; this project can
be used as a form of government responsibility in
preserving and protecting the environment. The
ultimate goal remains the same: avoiding conflicts or
disasters that will endanger the community.
2) The owner of capital here can be
exemplified as a bank that holds power over the
fortune of entrepreneurs. The benefit of having an
EIA for capital owners is that it is easy to provide
loan capital for a development or project. That is if a
party borrows money from a bank to build a project
and the EIA of the project is good and of good
quality. So, banks must provide loans for this
development.
3) The next benefit of EIA is for project
owners or companies, where EIA is essential for a
company. The EIA will benefit the project owner
because it will guarantee that project development
will continue without violating the applicable laws
and regulations. An example is when a housing
complex is constructed; the developer must have a
good EIA. That way, the government and capital
owners will give permission easily. In addition, the

community also did not feel disturbed by this
development.
4) The last benefit is for the community or
residents. EIA provides valuable benefits for the
district to know about specific development plans. In
addition, the community can also become supervisors
of projects that are being implemented. EIA
empowers the community to be more vigilant and
conscious of the various development projects. For
instance, in creating a national park, the community's
involvement ensures that the project respects
environmental considerations, such as preserving
animal habitats and minimizing disturbances.
2.2 Corporate Social Responsibility Theories
(CSR Theories)
Corporate Social Responsibility (CSR) is the
responsibility of an organization towards society and
the environment, which involves conducting business
ethically and responsibly, considering both internal
and external aspects of the organization. The goal is
sustainable development, [12]. This theory posits that
business organizations adhering to solid ethical
values acknowledge the importance of societal
responsibility. These businesses recognize that an
organization's social responsibility can lead to
societal acceptance and should encompass four
dimensions: 1) Economic Responsibility, 2) Legal
Responsibility, 3) Ethical Responsibility, and 4)
Philanthropic Responsibility. Therefore, business
organizations must consider social responsibility
across all four dimensions to gain greater acceptance
from various segments of society. The social and
environmental responsibility of organizations is
categorized into seven activities, [13], including 1)
Promoting awareness of social issues, 2) Market
activities related to societal concerns, 3) Market
activities aimed at addressing social issues, 4)
Philanthropic donations, 5) Community volunteering
and support 6) Conducting business with social
responsibility and 7) Developing and delivering
products and services.
From this perspective, it becomes evident
that business organizations should not solely pursue
profit but also emphasize the importance of social
and environmental responsibility. Moreover, this
perspective underscores that business organizations
also thrive when society thrives.
2.3 Setting the Research Hypotheses
Based on the research objectives and relevant
literature, the researcher has formulated four research
hypotheses:
Hypothesis 1 (H1): Legal components directly
influence the consultant components.
Hypothesis 2 (H2): Legal components directly
influence the community components.
Hypothesis 3 (H3): Consultant components directly
influence the resource components.
Hypothesis 4 (H4): Resource components directly
influence the community components.
2.4 Research Conceptual Framework
A research conceptual framework has been developed
through a review of the literature, related research,
and hypothesis formulation, as depicted in Figure 1.
Fig. 1: Research Conceptual Framework
3 Research Methodology
3.1 Population and Sample Groups
The population used in this research consists of
entrepreneurs or industrial plant managers authorized
to operate in Thailand's Eastern Region, totaling
11,466 entities, [14]. This research employs
hypothesis testing and analyzes results using
Structural Equation Modeling (SEM). The number of
sample groups used for analysis is calculated based
on the proportion between the sample units and the
number of parameters or variables, as per the
formula, [15]. It is recommended that the appropriate
number of sample groups for multivariate analysis
should be at least 5-10 times the number of
indicators. Since this research involves a
questionnaire with 40 questions, the minimum
number of sample groups should be approximately
400. Therefore, data was collected from 500 sample
groups using purposive sampling.

3.2 Research Tools
A purposive sampling technique was used to select
the sample group for the qualitative research
conducted through in-depth interviews with nine
experts. The research tools used for this phase of the
study were structured interviews, with the researcher
outlining the interview guidelines into four
components: legal aspects, company components
involved in preparing reports, resource components,
and community components. The structured
interview questions were of an open-ended nature.
Subsequently, the researcher designed a draft
questionnaire, which was used for the quantitative
research. This questionnaire was in the form of a
Rating Scale, with five levels of evaluation based on
Likert's method, [16]. The researchers ensured the
quality of the questionnaire, which was examined by
five experts with knowledge and experience in the
area to assess the quality of the tool using the Index
of Item-Objective Congruence (IOC). The index
value for item congruence with the research
objectives ranged from 0.60 to 1.00, with the
appropriate value being 0.50 or higher, [17]. The
researcher then conducted a Try-Out with 30
participants who shared similarities with the intended
research population. This Try-Out aimed to determine
the Discrimination values for checklist-type
questions. The Standard Deviation (S.D.) and
Correlation values were analyzed in the rating scale
questions. The reliability analysis of the
questionnaire revealed a Discrimination value
ranging from 0.45 to 1.39, and the overall reliability
of the questionnaire was calculated to be 0.99,
considered excellent, [18]. Following this validation
process, the research tools were used for data
collection by requesting responses through
questionnaires from the sample group.
3.3 Data Analysis
Data analysis involved both descriptive statistics and
inferential statistics using the SPSS software. The
AMOS software was utilized for multivariate
statistical analysis and structural equation modeling.
Four criteria were employed to assess the data-model
fit: 1) The p-value (probability value) should be more
significant than 0.05 2) The CMIN/DF (Chi-square
divided by degrees of freedom) should be less than
2.00 3) The GFI (Goodness of Fit Index) should be
greater than 0.90 and 4) The RMSEA (Root Mean
Square Error of Approximation) should be less than
0.08, [19]. Outlining four criteria for structural
equation modeling, researchers must adapt their
research models to meet all of these criteria.
Therefore, the model can be considered complete
acceptance and reliable according to the principles of
the research process.
4 Results
The analysis of the research objectives, which aimed
to study the components of the environmental impact
reduction guidelines in the Eastern Economic
Corridor (EEC) of Thailand's industrial sector,
consisted of 4 components: Component 1, Legal
Aspects; Component 2, Companies Providing
Advisory Services (Consultant); Component 3,
Resource; and Component 4, Society (Community).
These four components were derived from a
literature review and related research. Based on the
analysis of the structural equation model developed
by the researcher, it was found that the model did not
meet the criteria for data fit, with a p-value of 0.000,
CMIN/DF of 3.482, GFI of 0.781, and RMSEA of
0.071. The statistical significance was at the 0.001
level, which did not meet the criteria. Therefore,
adjustments were made to the model by considering
pairs of variables with the highest Modification
Indices (M.I.). The model was adjusted using three
methods, [20]: 1) Adjusting the components by
removing certain variables, 2) Adjusting the
components by combining variables, and 3)
Adjusting the components by adding arrows; the
adjusted model showed a good fit with the data, with
a p-value of 0.091, CMIN/DF of 1.272, GFI of 0.980,
and RMSEA of 0.023. The statistical significance
was at the 0.001 level and met the criteria established
in compatibility with the literature and empirical
data, as shown in Figure 2.
Thirteen observational variables are explained
after the model is consistent with the empirical data,
as shown in Table 1.
Results of hypothesis testing to analyze the
causal influence of latent variables in the structural
equation model of environmental impact reduction
guidelines in the industrial sector of the Eastern
Region of Thailand are four hypotheses as follows:

5 Discussion
The results of the model analysis based on the
research hypotheses, as depicted in Figure 2, can be
discussed as follows:
5.1 Legal Component
The legal component significantly influences the
component related to companies providing consulting
services for report preparation. This finding aligns
with, [21], which studied the legal consulting role in
terms of responsibility and societal impact. It
revealed that when legal consulting companies for
businesses in Indonesia operate transparently, comply
with laws and regulations, possess practical
communication skills, and make informed decisions;
they can foster positive relationships between
businesses and communities. These companies can
also contribute to achieving a balance between
economic, environmental, and social problem-

solving. Additionally, the study by, [22] found that
amending specific regulations and procedures to
make them more accessible and manageable resulted
in legal consulting companies working more
effectively. 2) The legal component also directly
influences the community component. This result is
in line with findings from, [23], which concluded that
empirical research in China showed that perceived
behavioral control, subjective norms, inward attitude,
and outward attitude all positively affect
environmental intentions, indirectly affecting the
environmental behavior of citizens and
environmental activists. Moreover, legal awareness
positively moderates the relationship between
environmental preferences and behaviors. As public
legal awareness increases, the direct influence of
these environmental intentions on environmental
behaviors also continues to grow. These findings
provide valuable insights for governments and
legislators to enhance public engagement in
environmental protection. Additionally, the study by,
[24] indicated that the effectiveness of environmental
impact assessments, as perceived by supporters,
increases public acceptance.
5.2 Consultant Component
The consultant component directly influences the
resource component, in alignment with findings
from, [25]. This study highlights the primary roles of
environmental consultants in two regulatory
programs, emphasizing their roles as trusted
facilitators in interactions between regulatory bodies
and businesses. They also serve as guardians of
public values, which have been relatively
underrepresented in existing literature on business
and environmental issues. Furthermore, the work of,
[26] stresses that environmental consultants provide
guidance and support to industries involved in
environmentally-related projects and sustainable
development. Competency evaluation allows
organizations to define the potential of existing
competencies and identify areas for improvement.
5.3 Resource Component
The research results by, [27] are helpful for business
entrepreneurs who require effective long-term
relationship management strategies to enhance value
co-creation among business partners. Resource
sharing was the most potent tool for co-creating
values among business partners. The resource
component directly influences the community
component, as corroborated by, [28]. The findings are
community monitoring can track environmental
phenomena, resource use, and natural resource
management processes of concern to community
members. It can also contribute to planning and
decision-making and empower community members
in resource management. Enhancing community
monitoring effectiveness requires improved data
collection, more efficient data management and
sharing, and more robust efforts to address
community information needs. It should also
facilitate conflict resolution and reinforce self-
determination. As highlighted by, [29], managing
natural resources using environmental-forest
education to generate information about natural
environmental phenomena has become a key factor.
Therefore, forms of environmental forest education
and community participation hold growing
importance nowadays.
6 Conclusion
Based on the testing of hypothesis 3 (H3), it was
found that the component related to environmental
consultants directly influences the resource
component with the highest Standardized Regression
Weight of 0.88. This result indicates that consulting
companies must carry out environmental impact
reporting processes according to the legal
requirements to produce transparent evaluations,
resulting in increased community acceptance of the
information presented in the reports. Government
agencies, on the other hand, must enforce legal
regulations rigorously. The environmental impact
assessment system aims to promote transparency in
safeguarding the industrial sector's social,
environmental, and public health aspects. Therefore,
every organization, whether governmental or
consulting companies, should fulfill their duties
transparently by legal principles, fostering
sustainable business growth.
7 Suggestions
1) The government should intensify legal
amendments related to environmental impact
assessments and enforce laws more rigorously to
penalize project owners who collaborate with
consulting companies in providing false
environmental impact assessment reports.

2) Industrial establishments should initiate
their operations by adhering to relevant regulations
and engaging sincerely in activities with the public or
communities. This strategy will help foster better
relationships, thereby enhancing the image of
industrial establishments.
3) The consultant should work transparently
and conduct comprehensive environmental impact
assessments following legal procedures.
4) The local community affected by
environmental impacts should become more engaged
and express their views directly in the environmental
impact assessment process. This acting will lead to
high-quality feedback and informed opinions.
