CRPD/C/GC/2 36. Ensuring full access to the physical environment, transportation, information and communication, and services open to the public is indeed a vital precondition for the effective enjoyment of many rights covered by the Convention. In situations of risk, natural disasters and armed conflict, the emergency services must be accessible to persons with disabilities, or their lives cannot be saved or their well-being protected (art. 11). Accessibility must be incorporated as a priority in post-disaster reconstruction efforts. Therefore, disaster risk reduction must be accessible and disability-inclusive. 37. There can be no effective access to justice if the buildings in which law-enforcement agencies and the judiciary are located are not physically accessible, or if the services, information and communication they provide are not accessible to persons with disabilities (art. 13). Safe houses, support services and procedures must all be accessible in order to provide effective and meaningful protection from violence, abuse and exploitation to persons with disabilities, especially women and children (art. 16). Accessible environment, transportation, information and communication, and services are a precondition for the inclusion of persons with disabilities in their respective local communities and for them to have an independent life (art. 19). 38. Articles 9 and 21 intersect on the issue of information and communication. Article 21 provides that States parties “shall take all appropriate measures to ensure that persons with disabilities can exercise the right to freedom of expression and opinion, including the freedom to seek, receive and impart information and ideas on an equal basis with others and through all forms of communication of their choice”. It goes on to describe in detail how the accessibility of information and communication can be ensured in practice. It requires that States parties “provide information intended for the general public to persons with disabilities in accessible formats and technologies appropriate to different kinds of disabilities” (art. 21 (a)). Furthermore, it provides for “facilitating the use of sign languages, Braille, augmentative and alternative communication, and all other accessible means, modes and formats of communication of their choice by persons with disabilities in official interactions” (art. 21 (b)). Private entities that provide services to the general public, including through the Internet, are urged to provide information and services in accessible and usable formats for persons with disabilities (art. 21 (c)) and the mass media, including providers of information through the Internet, are encouraged to make their services accessible to persons with disabilities (art. 21 (d)). Article 21 also requires States parties to recognize and promote the use of sign languages, in accordance with articles 24, 27, 29 and 30 of the Convention. 39. Without accessible transport to schools, accessible school buildings, and accessible information and communication, persons with disabilities would not have the opportunity to exercise their right to education (art. 24 of the Convention). Thus schools have to be accessible, as is explicitly indicated in article 9, paragraph 1 (a), of the Convention. However, it is the entire process of inclusive education that must be accessible, not just buildings, but all information and communication, including ambient or FM assistive systems, support services and reasonable accommodation in schools. In order to foster accessibility, education as well as the content of school curricula should promote and be conducted in sign language, Braille, alternative script, and augmentative and alternative modes, means and formats of communication and orientation (art. 24, para. 3 (a)), with special attention to the appropriate languages and modes and means of communication used by blind, deaf and deaf-blind students. Modes and means of teaching should be accessible and should be conducted in accessible environments. The whole environment of students with disabilities must be designed in a way that fosters inclusion and guarantees their equality in the entire process of their education. Full implementation of article 24 of the Convention should be considered in conjunction with the other core human rights instruments as well as the provisions of the Convention against Discrimination in Education of the United Nations Educational, Scientific and Cultural Organization. 11
