This Guide provides guidance on addressing aspects of climate change adaptation in European standardization documents. This Guide is applicable to product (including design), service, infrastructure and testing standards. For the purposes of this Guide, the definition of the term “product” has been expanded to cover all these aspects. It is intended to be applicable to both "climate-influenced products" and "climate resilience products" (see the definitions). It is primarily intended for standard writers and aims to enable them to: — identify relevant climate impacts; — include climate change adaptation considerations in new or revised standardization documents. Whenever a new standard is drafted or an existing standard is revised or intended to be revised, the TCsecretaries and their technical committee chairman/convenors are encouraged to actively promote the application of this Guide.
