Since the protection of natural resources requires the contribution of many parties, the need of assessment of an integrated set of programs initiated by host countries which matched with those of home countries is essential to halt massive environmental damage. For instance, the 2008 Transparency International’s report on promoting revenue transparency in oil and gas industries showed that International Oil Corporations (IOCs) such as Shell and BP Group had attained better results in reporting anticorruption programs and ecological operations in host governments due to improvement in their home countries’ regulations.
