Why HKA
Our experts help clients avoid disputes and manage risks, as well as supporting them through arbitration, adjudication and litigation. Eminent specialists in their fields, they combine industry insights with the well-honed testifying and presentational skills critical for communication and credibility.
We have handled complex environmental case across the globe – from a hurricane-hit oil refinery to international Energy Charter Treaty arbitrations, and from alleged ‘forever chemicals’ contamination to stranded assets.
Our Environment & Climate practice resolves the challenges facing clients across five broad areas:
Tighter regulations and landmark court decisions are transforming compliance requirements and compensation rights. Our team of air and noise experts includes specialists in industrial air emissions and air quality assessment, management and modelling.
Contaminated land can be a lottery with missed hotspots, historic contaminants mobilised during remediation or construction, bounce-back risks for sellers, and indemnities for unknown liabilities. HKA commands the diverse expertise needed to achieve certainty.
Pollutant-free water is a human right driving regulation, enforcement and litigation. Our expertise spans onshore and offshore, clean and dirty water assessment from a position of global leadership in policy and science.
Waste is both a potential hazard to human health and a material resource. Amid tightening legislation, we are supporting clients in disputes over the definition of waste, asbestos, forever chemicals, landfill reuse, waste facility construction and project stewardship, among other issues.
