Toward a New Scenario in Agricultural Sustainability Certification? The Response of the Indonesian National Government to Private Certification:

Abstract: This article discusses a new development in the relationships between private sustainability standards and governments, one in which Southern governments reclaim the authority from mainly Northern-based businesses and nongovernmental organizations. It examines how the Indonesian government, a forerunner in this field, responds to the private certification of palm oil. The results of this in-depth study are compared with similar trends in the coffee and cocoa sectors in Indonesia. The article observes that a change takes place from a nonresponsive stance, a modest involvement in terms of sustaining the implementation of private certifications, to an active development of alternative public national standards and certifications. The article defines some factors that facilitate the development of Southern public standards as an addition or alternative to private regulations and reviews the implications for the future of private standards and certification.

A Long Way to Implement Environmental Reporting in Indonesian Mining Companies

Abstract: This study aims to identify the antecedents of environmental reporting (ER) disclosure of mining companies in Indonesia. The population of this study was all mining companies listed in the Indonesia Stock Exchange (IDX). Using purposive sampling, the study collected 120 data from 30 companies. Correlation and path analyses identified four antecedents of ER i.e. length of listing in stock exchange (AGE), Company Size, Leverage, and Profitability. There were significant impacts of SIZE, AGE, Leverage, and Profitability on ER. SIZE significantly influences Leverage while AGE impacts on profitability. The practice of ER among mining companies is very much related to business strategies. ER would be widely reported by the companies when they have high leverage and unsatisfactory financial performance. Without tight supervision and hard enforcement from concerned parties, the implementation of appropriate ER disclosure in mining companies would have a long way to go.
