Introduction
Climate change is impacting organizations in various ways and it is anticipated that these impacts
will continue well into the future. Organizations have an increasing need to understand, mitigate and
manage climate change risks. Climate change risk assessment is key in this context. For responses
to be delivered at the necessary pace and scale, it is important that risk assessment approaches are
systematic and replicable, permitting learning within and between assessments as new knowledge,
technology and experience arise. This document provides guidelines on approaches to assess climate
change-related risks.
Risk assessments improve planning of adaptation to climate change and inform the implementation and
monitoring of climate change adaptation activities. Adaptation is usually more effective when initiated
at an early stage of project development, and when undertaken as a planned process rather than in
response to experienced impacts. Better knowledge of climate change risks will make it easier and less
costly to respond.
Climate change risks differ from other risks. It is often difficult or even impossible to quantify their
short- or long-term probability so a conventional risk assessment that uses statistical probabilities can
be ineffective. For this reason, various approaches have been developed for assessing climate change
risks. This document provides guidance on the use of screening assessments and impact chains. The
screening approach can serve as a stand-alone, simplified risk assessment for a straight-forward
system at risk or for organizations with a limited budget, or serve as a pre-assessment prior to the use
of impact chains. Based on a participatory and inclusive process, impact chain approaches are more
comprehensive, providing an opportunity to address all relevant factors. Both screening assessments
and impact chain assessments allow for qualitative and quantitative analysis.
This document is relevant to any organization regardless of size, type and nature. For example, it can
help financial institutions with decisions in project financing, companies operating in climate-sensitive
business sectors or local governments developing adaptation strategies.
This document covers risks that result from a changing climate. It does not address risks that result
from the transition to a low carbon economy. This document recognizes that climate risks can be
threats or opportunities.
This document emphasizes comprehensive documentation and communication of climate change risks;
these are essential for all subsequent activities. Risk assessments, among other purposes, provide
information on identifying adaptation actions and prioritizing them. Risk assessments conducted in
accordance with this document also strengthen planning activities on disaster risk reduction (DRR).
This document can be applied by organizations that want to carry out climate change risk assessments
[in the sense of the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change
(IPCC)] as well as by organizations that want to carry out vulnerability assessments (in the sense of the
IPCC AR4). However, it uses risk assessment as the central term.
This document belongs to an emerging family of standards on adaptation to climate change under the
umbrella of ISO 14090, which describes the following elements of climate change adaptation:
— pre-planning;
— assessing impacts including opportunities;
— adaptation planning;
— implementation;
— monitoring and evaluation;
— reporting and communication.
This document is part of the second item on the above list: “assessing impacts including opportunities”.

International Standards also deal with climate change or are in some way linked to this document. For
example, ISO 31000 is an excellent companion because it can help organizations manage the risks that
are identified and assessed in this document, which itself is a specialized expansion of the limited risk
assessment portion of ISO 31000. ISO 14001 allows for the integration of climate change adaptation
into an environmental management system and this document provides additional information to
support this.
This document is a guidance document for people working in the field of climate change.
This document is structured starting with an introduction to the concept of climate change
risk assessment, followed by the preparation, the implementation and the documentation and
communication of the climate change risk assessment.
The guidelines provided in this document are accompanied by supporting examples and information.
In this document, the following verbal forms are used:
— “should” indicates a recommendation;
— “may” indicates a permission;
— “can” indicates a possibility or capability.

Adaptation to climate change — Guidelines on
vulnerability, impacts and risk assessment
1 Scope
This document gives guidelines for assessing the risks related to the potential impacts of climate
change. It describes how to understand vulnerability and how to develop and implement a sound risk
assessment in the context of climate change. It can be used for assessing both present and future climate
change risks.
Risk assessment according to this document provides a basis for climate change adaptation planning,
implementation, and monitoring and evaluation for any organization, regardless of size, type and nature.
