1. INTRODUCTION

The ISO 14001 standard was first published by International Organization for Standardization (ISO) in 1996, and was further updated in 2004 and 2015. Its intent is to allow businesses to be registered or certified for implementing an environmental management system (EMS). It was designed to help organizations to reduce environmental impact while improving financial and environmental performance (BANSAL; HUNTER, 2003). By holding ISO 14001 certificate companies enhance stakeholders’ reliability (ISO, 2015). According to ISO, there have been more than 300,000 ISO 14001 certificates issued around the world and most of them in Europe and East Asia & Pacific regions.

Organizations seek to implement ISO 14001 standard for environmental, organizational and financial reasons, including: improvement of environmental performance, obtaining access to new and international markets, reducing general and insurance costs as much as environmental liabilities, improving industry-government relations and enhancing public image and competitive advantage (EDWARDS, 1999).

After its first issue in 1996, ISO 14001 standard has undergone two versions ISO 14001:2004 and ISO 14001:2015. Before promoting changes to the 2004 version in order to publish the 2015 version, ISO performed a survey to understand the view of the standard users on motivations, results and expectations for next revision.

Several authors remarked the importance of exports on the trends of companies in specific countries to seek ISO 14001 certification.

According to Berliner and Prakash (2013) countries adopted ISO 14001 when customers and stakeholders overseas recognized this approach and internally environmental regulations were poorly enforced. According to Goedhuys and Sleuwaegen (2016) EMS matters more to firms that export. Potoski and Prakash (2006) observed that countries, which export destinations, had higher levels of ISO 14001 certifications showed also higher certification levels. Based on that, they affirmed that ISO 14001 adoption was not about the quantity companies had been exporting but which countries had received these exports. Both groups Chung et al. (2005) and Zeng et al. (2005) affirmed that China started its adoption to enter in the international market and to satisfy customers’ requirements.

Some authors show that not always the ISO 14001 certification in countries is related to the direction of trade – export or import. For example, Potoski and Prakash (2004) identified among nongovernmental companies in 59 countries that level of ISO 14001 adoption was higher when its international trading partners also had adopted this regime. Mohamed (2001), Quazi et al. (2001), Fryxell and Szeto (2002), Pan (2003) and Zutshi and Sohal (2004) indicated that reduction or elimination of international trade barrier was a motivation to implement it.

The point of view of importers has also been studied. Bellesi et al. (2005) through a survey with six European countries discovered that importers feel more confident engaging a new supplier awarded with ISO 14001 because it means the supplier administrates well its business and it is environmentally friendly. According to Nishitani (2010), companies which aimed to export to environmental conscious markets needed ISO 14001 certification. This can also be seen in studies that dealt with the supply chain in international markets. For example, To and Lee (2014) showed that developed countries, due to the higher availability of resources, adopted first ISO 14001 and through close cross-country supply chain diffused it from west to east (TO; LEE, 2014).

Finally, the importance of ISO 14001 in international trade is pointed out for the possibility of recovering a country from the crisis by reinforcing trade, and the potential of ISO 14001 as a market opener. Iatridis and Kesidou (2016) affirmed that companies in middle crises, like Greek firms, seek ISO 14001 to restore their reputation in foreign markets and to stimulate their competitiveness.

This article’s purpose is to investigate possible correlations between ISO 14001 implementation and international trade in the countries where organizations operate.

2. LITERATURE REVIEW

As a preliminary information, it is important to describe the context of ISO 14001 continuous improvement research.

2.1. Motivations to implement ISO 14001 and the potential benefits

The early adopters had their motives to implement the standard. Edwards (1999) recognized six areas that encouraged companies to pursue certification: environmental performance, regulatory effectiveness, management effectiveness, competitive advantage, financial impacts and stakeholders’ interest. Bansal and Hunter (2003) through a US firms study identified that companies could differentiate their business in their sector creating a competitive advantage or signalizing to stakeholders that a heavy polluter was concerned about environment. Besides that, they found evidence proving that ISO 14001 facilitated international trade.

The literature has been saying that, through ISO 14001, institutions can access specific markets, achieve better public image, among others (MOREIRA, 2001; ABNT, 2004). Improvement on environment performance was met by several organizations in Mexico (DASGUPTA et al., 2000), United States (POTOSKI; PRAKASH, 2005), and Japan (ARIMURA et al., 2008). It also says that companies significantly performed better in environmental issues after ISO 14001 certification than they did before (MATELA, 2006); besides that, it can bring to organizations financial benefits besides good environmental practices (ALBERTON; COSTA JR, 2007).

De Oliveira, Serra and Salgado (2010) researched Brazilian companies to identify which benefits were achieved. They found that development of preventive responses, reduction of energy, gas and oil consumption were the main benefits. Morrow and Rondinelli (2012) studied German companies and collected answers on improvement on documentation, organization and image, boost in staff morale, reduction in resources usage and gas emission. German companies were proud to be a benchmark for suppliers, even if they had achieved it on their own process optimization only partially.

Institutional theory seems to be the predominant theory referential when discussing why companies go to ISO 14001 certification. Table 1 summarizes some of the categories of motivations found in scientific literature.

2.1.1. Literature that remarks benefits achieved

Literature is not always consistent regarding real benefits and results from the implementation of ISO 14001. Some literature authors say results are good, others say results are not any different from the non-certified companies.

A number of papers have been published bringing positive results in companies that implemented ISO 14001. The papers include results in countries such as USA, Canada, Italy, Portugal, Sweden, Greece, East Asia, China, Brazil, New Zealand and Nigeria. Benefit categories have been chosen as a way to make the overview easier to understand.

Some specific issues to be remarked is that the specific environmental issues that have been reported as improvements were waste management (ZUTSHI; SOHAL, 2004; PSOMAS et al., 2011; DJEKIC et al., 2014; OWOLANA; BOOTH, 2016; TESTA et al., 2016; MELNYK, 2002; MELNYK, 2003), natural resources usage (SANTOS et al., 2016) and toxic releases (SZYMANSKI; TIWARI, 2004). Supply chain relationship improvements have been reported as well (ZENG et al., 2005).

Relationship with stakeholders	Poksinska et al. (2003); Zeng et al. (2005); Gavronski et al. (2008); Psomas et al. (2011)

Regarding management tools, cleaner production was the only specific management tool cited (ZENG et al., 2005). Examples of specific internal improvement in management were the assistance to management in environmental matters (TO; TANG, 2014), emergency preparedness activities (DJEKIC et al. (2014) and the improvement in work environment (YIRIDOE et al., 2003).

Some studies remark that there are conditions to perceive benefits. For example, Gavronski et al. (2013) said that Brazilian companies with external motivations improved processes efficiency and environmental management.

2.1.2. Literature that remarks no benefits, or no significant difference

Bansal and Hunter (2003) differed from the majority of authors saying that in the United States ISO 14001 secured a competitive advantage, but only for first moves. ISO 14001 attracted new customers that demanded it, but only few of them were from the domestic market. Potoski and Prakash (2004) found that countries with high numbers of ISO 9001 certifications also had high numbers of ISO 14001 certifications and there was a non-linear relationship between wealth (per capita GDP) and number of ISO 14001 certifications, showing adoption decrease tendency for the wealthiest countries. Cañón and Garcés (2006) detected in Spain a benefit and a problem; there was a positive financial performance and a negative impact of certification on pioneer, middle polluting and lower size firms.

3. MEASURING INTERNATIONAL TRADE

Gross National Income based on purchasing-power-parity (GNIPPP), import and export figures were extracted from World Bank (2016) in US dollars on http://databank.worldbank.org/data/reports.aspx?source=world-development-indicators#.

3.1. Methods Description

3.1.1. Data Collection

The survey performed by ISO, between 2012 and 2013, used an electronic questionnaire, which was produced by ISO team. The details of the process are described in public report. The questionnaire was posted online in 11 languages, involving an ad-hc group with members from 10 different countries. The questionnaire was online from 30 January – 30 April 2013. The topics treated in the questionnaire-included information on the respondent. These pieces of information are about level of knowledge on ISO 14001, responsibility and interaction with management system and if he/she was answering from his/her personal point of view or as a view of the company, as well as information on the company and its environmental management system – size of company, sector, how long it had been certified, scope of certification and some implementation details. The opinions collected were divided in the following dimensions: motivations for implementation, benefits for the business, benefits for environmental performance, and on at which degree some concepts and requirements on sustainable development, corporate social responsibility, and product life cycle among others should be included in ISO 14001 revision (ISO, 2014a).

A total of 4925 answers have been received by ISO. However, from all these, 1749 were the respondents that were qualified as experienced users (current users or past users) and that answered as a member of a company and not from his/her individual view. These are the answers taken for the current work. From all respondents those that have never been involved in the practice with ISO 14001 management system and those who were not talking on behalf of a company have been removed from the basis, as well as those that did not answer to a full section.

ISO supplied the raw data, which provided the research team with a raw .xls file that included all answers. These are the most recent data available, once no other similar survey has been conducted. The sections of the questionnaire and the assertive used are described in table 3.

Table 3: Questionnaire sections used for this paper

Theme	Specific assertions	Scale
Motivations	Public image	1 – 8 (1 most important, 8 less important
	Customer requirement
	Government/regulatory agency requirement
	Commitment to environmental protection and conservation
	Reduction of risk related to adverse environmental impact
	Cost savings/financial benefit
	Opportunities for integration with other management standards applied by the organization (such as ISO 9001, ISO 50001, ISO 26000, OHSAS 18001)
	Other factors
Benefits - environmental management	Meeting stakeholder requirements	1 – 6 (0 – no value, 1 – low, 2 – moderate, 3 – high, 4 – very high and 5 – don´t know
	Achieving strategic objectives
	Providing a competitive advantage
	Improving public image
	Integrating with the business management system(s)
	Providing a financial benefit
Business management	Management commitment to environmental management	1 – 6 (0 – no value, 1 – low, 2 – moderate, 3 – high, 4 – very high and 5 – don´t know
	Employee engagement in environmental management
	Communication with stakeholders
	Stakeholder satisfaction
	Ability to meet legal requirements
	Improvement of the organization’s environmental performance
	Improvement in supplier environmental performance

The used answers were related to respondents work country and their motivations to adopt ISO 14001: public image, customer requirement, government requirement, environmental protection, environmental impact risk reduction, financial benefits and integration with other ISO management standards. Each answer has been associated with trade information of the country of operation of the firm.

In order to represent features of international trade in several countries, some variables have been used and their descriptions are in table 4.

Table 4: Variables used to understand country's international trade.

Name	Description
GNIPPP2012	Gross national income, standardized according to purchase power parity in 2012 (chosen because of the data of survey) in US dollars
EXPORT	Total exports of the country in US dollars
IMPORT	Total imports of the country in US dollars
BALANCE OF TRADE	Result of the balance of trade of the country in US dollars
Cert/ GNIPPP	Relation between certifications ISO 14001 and GNIPP
%Exp/GNIPPP	Percentage from relation between exports ISO 14001 and GNIPP
%Imp/GNIPPP	Percentage from relation between imports ISO 14001 and GNIPP
%Balance/GNIPPP	Percentage from relation between balance of trade ISO 14001 and GNIPP

3.2. Data Analysis

Correlations were tested for each assertive about motivation to implement, benefit to environmental management and benefit to business management.

Correlations have been tested using Spearman’s “rho” coefficient by Spearman. This choice is justified because the data distribution was not a normal one. The test has been performed under the significance level of 5% (p<0,05) (MYERS, 2006).

The distribution of the answers according to the countries has not been balanced, what can introduce some bias. However, the gains in this case would not bring significant benefit because the choice of balancing by trade weight or weighting by certification numbers in each country would be arbitrary.

4. RESULTS

4.1. Motivations to implement

The results from 48 possible correlations among international trade and motives to implement ISO 14001, presented on table 5, showed 16 significant ones, although all of them were weak. The motive customer requirement was negative with export amount (rho=-0,0955; p=0,0001), import amount (rho=-0,0799; p=0,0008) and balance of trade (rho=-0,0473; p=0,048). Proportion import/GNIPPP correlated positively (rho=0,0476; p=0,0466) with com customer requirement and other five items. Environmental protection resulted the highest positive correlations with proportional of export, import and balance of trade with GNIPPP and certifications/GNIPPP. Because the motivation scale is inverted (higher motivation is lower score) the conclusion is that higher importance of customer requirements were associated with higher exports and with higher balance of trade. On the other hand, higher importance of customer requirements is correlated with lower imports of the countries where the companies operate. It is also remarkable that public image, government requirement and financial benefits correlated with one single variable, showing that probably these benefits have very little role in the environmental management within international trade context.

4.2. Benefits for business

When looking at the correlations of international trade variables and the benefits for business, it is clear that a higher number of correlations occurred, as shown in table 6. Correlations occur both with import and export variables, what means that as a general rule more intense international trade is associated with higher perceived benefits from the business point of view. The correlations coefficients are still low, showing in general a weak correlation.

4.3. Benefits for environmental management

In the case of benefits for management, the results are in table 7. All surveyed benefits correlated with exports, imports and gross national product. This shows that in countries with higher GNIPPP, countries with higher exports and countries with higher imports have perceived fewer benefits for the environmental management. However, regarding balance of trade, only there were correlations between management commitment to environmental management and improvements in suppliers’ environmental performance.

5. DISCUSSION

The first result is that correlations, when existing, are low, showing that the influence of international trade in the motivations and benefits for the implementation of ISO 14001 are less important than literature such as Goedhuys and Sleuwaegen (2016); Both groups Chung et al. (2005) and Zeng et al. (2005); Bellesi et al. (2005) and Nishitani (2010) proposed.

5.1. Motivations for implementation

One of the issues that is more important is the customer requirements, which are quoted as an important driver for the implementation of ISO 14001. In the international trade context, the results show that it does have an importance, because as seen in table 5 the correlations show that the higher the numbers of international trade, both in absolute volume and as proportion of GNIPPP, the more the importance of customer requirements as a motivation for implementation of ISO 14001. This confirms the inclusion of customer requirements as a motivation for implementation, as proposed by Tuppura et al. (2015), Quazi et al. (2001), Fryxell and Szeto (2002), Yiridoe et al. (2003), Schylander and Martinuzzi (2007), ISO (2014), Djekic et al. (2014), Zeng et al. (2005) as a general rule and Bellesi et al. (2005), To and Lee (2014) specifically regarding international trade.

When looking at the specific variables, %ImportGNIPPP was correlated positively with six different motivations. Because of the inverted scale that means that there is a trend that the more important imports in the country's economy, the less important are these motivations.

5.2. Benefits for the business

It is noteworthy that most trade variables are negatively correlated to the surveyed benefits. That means that the more the country exports or imports, both as absolute numbers or proportion of GNP, the less benefits for the business are perceived. That is contradictory with the theory because it would be expected that as a general rule they would perceive benefits such as financial benefits as reported e.g. by Morrow and Rondinelli (2002) or in marketing by Poksinska et al. (2003), or specifically for international trade satisfying stakeholders’ requirements as noted by Bellesi et al. (2005).

5.3. Benefits for Environmental Management

All surveyed environmental management benefits were negatively correlated with GNIPPP, exports and imports volumes, that means that in countries with larger economies and in countries with larger volumes of imports and exports the perceived environmental benefits tend to be lower than in countries with less GNIPPP and less international trade. However, there was a slightly positive correlation between perceived benefits and the proportion of trade balance at the country, that means, in countries with a higher importance of positive trade balance the benefits are more perceived. Although only two of the benefits had some correlation with exports proportion, most of them had negative correlation with imports. Although the correlation coefficients are low, this also challenges expectations and literature that argues that these benefits occur and give reason to the skeptics.

6. CONCLUSIONS

The intention of this project was to identify the relation between ISO 14001 certification and its affect in import and export volume. The survey result shows that there are weak correlations among countries international trade and motives to get certification. Because the degrees of correlation are low, there is reason to additional studies, what could probably include multivariate techniques. Anyway, the study suggests that some of the expected results and benefits for the business are not being achieved, or are achieved at degrees lower than expected in countries where trade is higher.

Regarding motivations to implement the survey confirmed that attending to customers and stakeholders’ interests is an important driver for companies that export.

Because the correlations are low this study suggests that importance of ISO 14001 certification in international trade is smaller than expected by hypotheses in scientific literature.
