FAQs about our sustainability and ESG managed services

See our frequently asked questions (FAQs) below for a full list of sustainability and ESG-managed solutions.

What are sustainability and ESG managed services?
Sustainability and ESG managed services extend your team with professionals who run the recurring work behind ESG programs. You maintain control of your strategy while an external team manages data collection, reporting tasks, emissions calculations, supplier engagement and regulatory readiness. This approach improves consistency, strengthens data quality and reduces pressure during peak reporting periods.
What sustainability and ESG managed services does RSM offer?

What does RSM offer?

  • RSM offers an integrated delivery model with shared governance, communication, measures and tooling, giving you a single accountable team rather than a patchwork of vendors. This model draws on deep industry experience tailored and optimized to your business’s daily operations, improvement roadmap(s) and risk controls.
Why are sustainability and ESG managed services important?
Expectations from regulators, customers, lenders and investors continue to rise. ESG rules change each year and vary across regions. Many internal teams lack the time or technical experience to keep up. Managed services provide structure and reliable execution, allowing leaders to focus on goals, performance and risk reduction rather than ESG tasks.
What are the benefits of ESG managed services?
ESG managed services free your teams from time-consuming reporting work and help maintain compliance with changing regulations. They help reduce risk by keeping your disclosures aligned with global and local rules. They also improve efficiency by providing clearer, more reliable data to guide investment decisions, target setting and long-term planning. Stronger reporting builds trust with customers, investors and stakeholders who expect accurate and meaningful sustainability information.
Why choose RSM’s sustainability and ESG managed services?
