<![CDATA[The study investigated the contribution of digital automation technologies towards environmental sustainability practices of companies in Nigeria, and their level of implementation of these technologies. Four research questions were raised to achieve the study objectives. Cross-sectional survey design was used in the study. A sample size of one hundred and eighty-nine (189) respondents were drawn from a target population of accountants, top business managers, and Information Technology experts of manufacturing firms in Nigeria. Primary data were collected from the respondents with the use of a 4-point Likert-based questionnaire. Analysis of data collected was achieved by using frequency counts and Spearman Ranked Order Correlation Coefficient. The results showed that only Internet of Services have been implemented to a high degree while other elements of industry 4.0 have low implementation in Nigeria. It was equally found that digital automation technology implementation significantly enhances waste management practices, reduction in carbon emission, and natural resource use efficiency. The study recommends that managers of manufacturing firms in Nigeria should endeavour to acquire, implement and maintain digitized manufacturing facilities that use connected devices, machinery and production systems to continuously collect and share data in order to help the firms achieve more efficiency in their production processes.]]>
