Climate Change

Customized intelligence for your unique weather and climate needs

in assessing the impacts of climate variability and change

The impacts of climate change are occurring around the world in different ways and at different rates. CFAN works with clients to evaluate and assess risks from climate change impacts for their organization or region.


CFAN’s climate change assessments drawing on years of experience working on projects for corporations and in vulnerable regions around the world. CFAN and its affiliates have expertise in the following sectors that are impacted by climate variability and change: transportation, energy, agriculture, forestry, water resource management, infrastructure and building construction, and financial services.  In addition to North America, CFAN team members have expertise and experience in the following regions: Central America, South America, and Asia.

CFAN’s climate services include:

  • Corporate climate risk management

  • Climate scenarios and impact assessments

  • Expert reports and testimony

Corporate climate risk management


Corporations face a broad array of risks related to climate change: market, operational, logistics, strategic, legal, regulatory, political and financial.


CFAN can help your organization reduce risks, identify new opportunities, and build resilience. We can help integrate climate science into your business and policy decisions:

  • Corporate risk assessments

  • Climate risk disclosure and vulnerability analysis

  • Corporate resilience strategy

  • Adaptation planning

  • Climate vulnerability assessments

Climate scenarios & impact assessment





Climate variability and change can have substantial impacts on strategic planning, infrastructure, capacity building, and needs for technology development.  CFAN has experience in producing climate impact assessments for individual institutions, industry sectors, and regional integrated impact assessments.  CFAN can undertake an independent climate risk assessment or support an established risk assessment team.

CFAN's climate impact assessments include historical analyses and decadal scale scenarios of future climate change that can be used to drive sectoral or regional risk assessment models.  Our scenarios of future climate change integrate projections of human-caused climate change with natural modes of climate variability.  Extreme event scenarios consist of frequency distribution of regional extreme events over the target time interval, as well as worst-case scenarios of individual events.  Providing a range of possible scenarios enables decisions that are robust across a range of possible outcomes, and allows for focus on scenarios in the vicinity of your vulnerability thresholds.

Support for litigation

Climate science is becoming increasingly important in litigation. According to the UNEP Global Review on the Status of Climate Change Litigation [link], as of March 2017, climate change cases had been filed in 24 countries, with 654 cases filed in the U.S.  
With the growing policy emphasis upon adaptation to climate change and attribution of the causes of extreme weather and climate events, the potential for disputes will multiply.
