Sustainability Strategy & Program Development Services
Developing a sustainability strategy and program can help companies better adapt to stakeholder demands and address reporting requirements.
Gain confidence in your sustainability reporting with independent sustainability assurance.
Reliable, consistent data should be at the heart of every sustainability program. BDO’s sustainability assurance services help you improve the quality of your reporting and earn stakeholder trust.
Stakeholders now expect sustainability reporting to be of the same caliber as financial reporting, calling for disclosures to be clear, accurate and reliable – and viewing claims with a healthy dose of skepticism. Sustainability-related regulations, such as California’s SB 253 and the EU’s Corporate Sustainability Reporting Directive (CSRD), require mandatory reporting and introduce independent sustainability assurance for those in scope.
BDO provides third-party sustainability assurance services that help enhance the credibility of your reporting and instill confidence in your data. Our team combines deep knowledge of the sustainability landscape and reporting standards with the discipline of seasoned auditors who carry a legacy of more than 100 years of quality service.
We offer sustainability assurance services at both the limited and reasonable levels. Our team will work with you to identify the appropriate level of sustainability assurance for your ESG information, taking into consideration where you are on your sustainability journey and what matters most to your stakeholders. We also support sustainability reporting and assurance readiness. We begin with a current state assessment of your ESG data, helping to establish governance oversight, processes and controls, and preparing high-quality disclosures.
In addition to sustainability compliance required by governments and regulators, companies are facing growing pressure from customers to report greenhouse gas (GHG) emissions data, set net zero goals, commit to supply chain responsibility and be evaluated by sustainability ratings providers such as EcoVadis and CDP. Our sustainability regulatory and reporting services can help you provide the information regulators and your customers need, coupled with sustainability strategies that make sense for your organization.
