Climate Change Expert Witnesses
Climate change disputes in commercial and regulatory litigation typically arise when companies, investors, or government bodies disagree about whether climate-related disclosures, environmental permits, or risk assessments accurately reflect the scientific evidence and applicable regulatory standards. These disputes surface in securities litigation over whether a company's climate-related disclosures and ESG statements in regulatory filings were accurate, in environmental permitting and regulatory litigation over whether a project's environmental impact assessment adequately addressed climate-related risks, and in insurance and property litigation over whether climate-related risk assessments adequately informed underwriting and coverage decisions. Because climate science involves complex atmospheric, oceanic, and ecological modeling, determining whether a specific climate-related claim or disclosure is scientifically supported requires specialized climate science expertise. The central issue is typically whether the climate-related evidence and modeling at issue supports the scientific, regulatory, or disclosure position a party has taken.
A climate change expert helps attorneys evaluate that question by applying accepted climate science and modeling methodologies to the disclosure, permit, or risk assessment at issue. That might mean assessing whether a company's climate-related securities disclosures were consistent with the underlying scientific and financial risk data, evaluating whether an environmental impact assessment adequately addressed climate-related risks such as flooding, drought, or wildfire exposure, or analyzing whether a property or insurance risk model's climate assumptions are scientifically sound. These findings support positions on securities liability, regulatory compliance, and insurance coverage, giving attorneys a scientifically grounded basis for litigation strategy.
Climate change cases benefit from experts whose specific background, whether atmospheric science, climate risk modeling, or environmental policy, matches the precise scientific or regulatory question at issue rather than climate change in general terms. Round Table Group's climate change network includes scholars and researchers from universities and research facilities with published work spanning climate modeling, environmental analysis, and climate-related policy. With more than 75,000 expert searches completed for litigators, we help attorneys match a case's specific climate change issue to an expert whose credentials will withstand scrutiny.

Environmental, Social and Governance (ESG) litigation has become dominated by climate lawsuits, most notably filed against global energy companies like Shell Plc and Exxon Mobil Corp. The scope of ESG litigation is expanding, as regulatory developments pose new potential risks for a wider range of organizations. These broadening risks can largely be attributed to the demand for mandatory reporting requirements coupled with current legislation in the area. Now, we are witnessing an influx of lawsuits against both governments and corporations based on ESG statements in securities filings.

Questions Attorneys Ask About Climate Change Expert Witnesses:
A climate change expert typically becomes necessary in securities litigation over whether a company's climate-related disclosures and ESG statements were accurate, environmental permitting litigation over whether an impact assessment adequately addressed climate-related risks, and insurance or property litigation over whether climate risk assessments informed underwriting decisions appropriately.
These experts can assess whether a company's climate-related disclosures are consistent with underlying scientific and financial risk data, evaluate whether an environmental impact assessment adequately addressed climate-related risks, and analyze whether a risk model's climate assumptions are scientifically sound. Many also address broader questions of climate modeling and environmental policy.
The expert's specific background, whether atmospheric science, climate risk modeling, or environmental policy, should closely match the scientific or regulatory question at issue, and an active publication record in that specific area strengthens credibility. Experience translating complex climate science for legal proceedings is also valuable.
A climate change expert's scientific analysis can establish whether a disclosure or risk assessment accurately reflected the underlying climate evidence, support or rebut a securities or regulatory compliance claim, and identify weaknesses in an opposing expert's climate modeling. That analysis is often central to both affirmative claims and rebuttal reports.
Round Table Group works with counsel to define the specific scientific, regulatory, or disclosure questions at issue, then sources and speaks with candidates to assess their directly relevant research experience. After confirming interest, availability, and completing conflict checks, we present a curated roster of qualified options for counsel to review.
