CRC/C/GC/26 States under article 24 of the Convention also apply when developing and implementing environmental agreements to address transboundary and global threats to children’s health. 43. The right to health includes access for children affected by environmental harm to high-quality public health and health-care facilities, goods and services, and particular attention should be given to underserved and hard-to-reach populations and to delivering high-quality prenatal maternal health care nationwide. Facilities, programmes and services should be equipped to respond to environmental health hazards. Health protection also applies to the conditions that children need to lead a healthy life, such as a safe climate, safe and clean drinking water and sanitation, sustainable energy, adequate housing, access to nutritionally adequate and safe food and healthy working conditions. 44. The availability of high-quality data is crucial for adequate protection against climate and environmental health risks. States should assess the local, national and transboundary health effects of environmental harm, including the causes of mortality and morbidity, while taking into consideration the entire life course of children and the vulnerabilities and inequalities that they face at each life stage. Priority concerns, the impacts of climate change and emerging environmental health issues should be identified. In addition to data collected through routine health information systems, research is required, for example, for longitudinal cohort studies and studies of pregnant women, infants and children that capture risks at critical windows of development. I. Right to social security and adequate standard of living (arts. 26 and 27) 45. Children have the right to a standard of living adequate for their physical, mental, spiritual, moral and social development. A clean, healthy and sustainable environment is a prerequisite for the realization of this right, including to adequate housing, food security and safe and clean drinking water and sanitation.10 46. The Committee underlines that the rights to adequate housing, food, water and sanitation should be realized sustainably, including with respect to material consumption, resource and energy use and the appropriation of space and nature. 47. Exposure to environmental harm has both direct and structural causes and exacerbates the effects of multidimensional child poverty. In the environmental context, social security, as guaranteed under article 26 of the Convention, is particularly relevant. States are urged to introduce features into social security policies and social protection floors that provide children and their families with protection against environmental shocks and slow-onset harms, including from climate change. States should strengthen child-centred poverty alleviation programmes in the areas that are most vulnerable to environmental risks. 48. Children, including displaced children, should have access to adequate housing that conforms to international human rights standards. Housing should be sustainable and resilient and should not be built on polluted sites or in areas facing a high risk of environmental degradation. Homes should have safe and sustainable sources of energy for cooking, heating, lighting and appropriate ventilation and be free from mould, toxic substances and smoke. There should be effective management of waste and litter, protection from traffic, excessive noise and overcrowding and access to safe drinking water and sustainable sanitation and hygiene facilities. 49. Children should not be subject to forced evictions without prior provision of adequate alternative accommodation, including relocation linked to development and infrastructure projects addressing energy and/or climate mitigation and adaptation action. Child rights impact assessments should be a prerequisite for such projects. Particular attention should be paid to preserving the traditional land of Indigenous children and protecting the quality of 10 8 Committee on Economic, Social and Cultural Rights, general comment No. 15 (2002) on the right to water, para. 3; and Committee on the Rights of the Child, general comment No. 15 (2013) on the right of the child to the enjoyment of the highest attainable standard of health, para. 48.
