A firm wishing to go global should consider passing ISO standards in order to demonstrate a commitment to best practices in terms of impacting the environment to international businesses.

Absolutely, obtaining ISO certification can be a significant step for a firm aiming to expand globally. Here are the steps a firm should consider:

1. Understand the ISO Standards: The first step is to understand what ISO standards are and how they apply to your business. ISO 14001, for example, focuses on environmental management systems.

2. Gap Analysis: Conduct a gap analysis to identify where your organization currently stands in relation to the ISO standard you wish to achieve. This will help you understand what changes need to be made.

3. Develop an Action Plan: Based on the gap analysis, develop an action plan to address the areas where your organization falls short of the ISO standard.

4. Implement Changes: Implement the changes outlined in your action plan. This could involve changing processes, investing in new equipment, or training staff.

5. Internal Audit: Once the changes have been implemented, conduct an internal audit to ensure that the changes are effective and that your organization is now in line with the ISO standard.

6. Certification Audit: After the internal audit, an external ISO auditor will conduct a certification audit. If your organization passes this audit, you will receive your ISO certification.

7. Continuous Improvement: ISO standards require continuous improvement, so it's important to regularly review and improve your systems and processes even after certification.

By following these steps, a firm can obtain ISO certification, demonstrating its commitment to best practices and making it more attractive to international businesses.
