Environmental Site
Assessments (ESAs)

An essential part of due diligence when buying commercial property is getting an environmental site assessment (ESA) before closing the deal.

Essentially, an ESA will help identify the existence and scope of soil or groundwater contamination (e.g., from petroleum, heavy metals, pesticides or herbicides), as well as the presence of hazardous products at sites such as asbestos, PCBs etc.

An ESA will determine whether environmental issues exist before you buy, and help you avoid costly surprises down the road.

Tailor-made Environment, Health and Safety (EHS) Audits

EHS stands for Environment, Health, and Safety. It's a general term used to refer to legislations, standards and workplace efforts to protect the health and safety of employees and the public as well as the environment from hazards associated with the workplace.

With a network of EHS specialists, ESS can help you implement an effective EHS improvement program wherever it is required.


Moreover, ESS can tailor audits according to your needs or existing corporate global or local standards. We can assess your legal EHS compliance level and advise for improvement.

Specialized Environment, Social and Governance (ESG) Services

While EHS is an operational, legislative and oftenly contractual requirement; EHS is more a subset of ESG since 'Environment' is a common aspect while Occupational Health and Employee Safety together with Corporate Social Responsibility comprise the 'Social' aspect of ESG. 'Governance' however, is mostly untouched by any aspect of EHS. 

Investors, customers, bankers, insurers, and other stakeholders and capital providers recognize that a company’s financial performance is tied to its proper management of its sustainability-related issues. 

Moreover, multilateral and bilateral development Finance Institutions (FIs) operate across various world regions to promote sustainable development. As part of their mandate, these institutions require that their financing activities are conducted in compliance with certain environmental and social requirements. Some of the most commonly used standards are  IFC Performance Standards, EBRD Performance Requirements and Equator Principles.

ESS's network of experts are capable of fulfilling environmental and social due diligence audits according to international or corporate standards. Moreover, if your company is lacking ESG professionals, we can assist you through capacity building.

Strategic Environmental Assessment (SEA)

A Strategic Environmental Assessment (SEA) is a systematic process for evaluating the environmental implications of a proposed policy, plan or programme and provides means for looking at cumulative effects and appropriately address them at the earliest stage of decision making alongside economic and social considerations.

ESS's network of experts are capable of supporting the Client to conduct a SEA process in compliance with the Strategic Environmental Assessment Regulation which has been enacted in 2017.
