1. Introduction

Sustainable Development Goal 3 (SDG 3) is one of the 17 Sustainable Development Goals adopted by the United Nations in September 2015 under the 2030 Agenda for Sustainable Development. Its main aim is to ensure healthy lives and promote well-being for all at all ages. It recognizes that good health is essential for individual development, social progress and economic growth.

Health is not limited to the absence of disease. It also includes physical, mental and social well-being. People need access to quality healthcare, nutritious food, safe drinking water, clean surroundings, vaccinations, health education and affordable treatment to lead healthy lives.

SDG 3 focuses on improving healthcare systems, reducing preventable deaths, controlling communicable and non-communicable diseases, promoting mental health, ensuring reproductive healthcare and making essential health services accessible to everyone.

The goal emphasizes equity in healthcare, meaning that access to health services should not depend on a person’s income, gender, age, disability or geographical location. It also recognizes that the health of individuals is closely connected with other development goals, including poverty reduction, nutrition, clean water, sanitation, sustainable cities and environmental protection.

2. Objectives of SDG 3

The major objectives of SDG 3 are:

1. Reduce maternal and child mortality: Prevent deaths during pregnancy, childbirth and early childhood through timely medical care.
2. Control communicable diseases: Prevent and treat diseases such as tuberculosis, HIV/AIDS, malaria and other infectious diseases.
3. Prevent non-communicable diseases: Reduce premature deaths caused by conditions such as cardiovascular diseases, cancer, diabetes and chronic respiratory diseases.
4. Promote mental health: Improve awareness, early identification and access to mental health support.
5. Achieve universal health coverage: Ensure that people can access essential health services without suffering financial hardship.
6. Improve road safety: Reduce deaths and injuries caused by road traffic accidents.
7. Ensure reproductive healthcare: Provide access to reproductive health information, services and family planning.
8. Reduce environmental health risks: Minimize illness caused by air pollution, unsafe water, hazardous chemicals and other environmental hazards.
9. Strengthen healthcare infrastructure: Improve health facilities, medical equipment, medicine availability and the healthcare workforce.
10. Improve emergency preparedness: Strengthen the ability of health systems to respond to epidemics, pandemics and other health emergencies.

These objectives form the foundation of the goal’s 13 targets.

3. Targets of SDG 3

SDG 3 contains 13 targets, numbered 3.1 to 3.9 and 3.a to 3.d. These targets cover specific health outcomes, access to services and the systems needed to improve public health.

Target	Description
3.1: Maternal health	By 2030, reduce the global maternal mortality ratio to less than 70 deaths per 100,000 live births. This requires antenatal check-ups, skilled birth attendants, emergency obstetric care and postnatal services.
3.2: Newborn and child health	End preventable deaths of newborns and children under five. The targets include neonatal mortality of no more than 12 deaths per 1,000 live births and under-five mortality of no more than 25 per 1,000 live births.
3.3: Communicable diseases	End epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases, while combating hepatitis, waterborne diseases and other communicable diseases.
3.4: Non-communicable diseases and mental health	Reduce premature mortality from non-communicable diseases by one-third through prevention and treatment, and promote mental health and well-being.
3.5: Substance-use prevention and treatment	Strengthen the prevention and treatment of substance-use disorders, including drug abuse and the harmful use of alcohol.
3.6: Road safety	The original 2030 target was to halve global deaths and injuries from road traffic accidents.
3.7: Sexual and reproductive healthcare	Ensure universal access to sexual and reproductive healthcare services, family planning, information and education.
3.8: Universal health coverage	Achieve universal health coverage, including financial risk protection, access to quality essential healthcare and safe, effective, affordable essential medicines and vaccines.
3.9: Environmental health	Substantially reduce deaths and illnesses caused by hazardous chemicals, air pollution, water pollution and soil contamination.
3.a: Tobacco control	Strengthen implementation of the World Health Organization Framework Convention on Tobacco Control.
3.b: Medicines and vaccines	Support research and development of vaccines and medicines, improve access to affordable essential medicines and vaccines, and address diseases affecting developing countries.
3.c: Healthcare workforce	Increase health financing and the recruitment, development, training and retention of healthcare workers, particularly in developing countries.
3.d: Health emergency preparedness	Strengthen early warning, risk reduction and management of national and global health risks.

Understanding the targets

These targets can be understood through three broad areas:

• Improving health outcomes: Targets 3.1 to 3.7 focus on preventing deaths, controlling diseases, improving maternal and child health, and promoting mental and reproductive health.
• Making healthcare accessible: Target 3.8 focuses on universal health coverage, while 3.b and 3.c support affordable medicines, vaccines and a trained healthcare workforce.
• Building a resilient health system: Targets 3.a, 3.9 and 3.d address tobacco control, environmental risks and preparedness for health emergencies.

Together, these areas aim to create a healthcare system that prevents illness, treats disease effectively and protects people throughout their lives.

4. Importance of SDG 3

A. Improvement in quality of life

Good health enables people to participate in education, employment, family life and community activities. Preventive healthcare, timely diagnosis and treatment can reduce avoidable suffering and improve life expectancy.

B. Reduction in poverty and inequality

Serious illnesses can force households to spend a large portion of their income on treatment or lose earnings when family members cannot work. Affordable healthcare and financial protection can reduce this burden, particularly for low-income households.

C. Maternal and child welfare

Access to maternal care, skilled birth attendance, immunization, nutrition and newborn services improves the chances of healthy pregnancies and childhood development. These interventions are particularly important in underserved rural and urban communities.

D. Economic development

A healthy population can contribute more effectively to the economy. Better health reduces preventable absence from work and school, supports productivity and reduces the financial pressure associated with avoidable medical treatment.

E. Disease prevention and emergency preparedness

Strong public health systems help detect outbreaks, provide timely treatment and communicate risks to communities. Surveillance, vaccination programmes and emergency planning can reduce the impact of infectious diseases and other health threats.

F. Environmental sustainability

Air pollution, contaminated water, poor sanitation, unsafe housing and exposure to hazardous substances can contribute to disease. SDG 3 therefore connects healthcare with environmental management, sanitation, housing and sustainable urban development.

5. Major challenges in achieving SDG 3

Despite progress in healthcare, several challenges continue to affect its achievement by 2030.

1. Unequal access to healthcare: Rural, remote and underserved urban communities may lack nearby facilities, specialists, medicines or diagnostic services.
2. High healthcare costs: Out-of-pocket expenditure can place significant financial pressure on households, especially when treatment requires hospitalization.
3. Shortage of trained professionals: Uneven distribution of doctors, nurses, specialists and other healthcare workers can reduce the quality and availability of care.
4. Communicable diseases: Tuberculosis and other infectious diseases continue to require sustained prevention, diagnosis, treatment and public awareness.
5. Non-communicable diseases: Cardiovascular diseases, diabetes, cancer and chronic respiratory diseases create a growing need for prevention and long-term care.
6. Mental health concerns: Stigma, limited awareness and inadequate access to trained professionals can prevent people from seeking support.
7. Environmental pollution: Poor air quality, contaminated water, inadequate sanitation and unsafe waste disposal contribute to health risks.
8. Road traffic injuries: Unsafe roads, insufficient pedestrian facilities and inadequate road-safety measures expose people to preventable injuries.
9. Emergency preparedness: Disease outbreaks, climate-related disasters and other emergencies can disrupt essential healthcare services.
10. Data and monitoring gaps: Incomplete or outdated health data can make it difficult to identify vulnerable populations and allocate resources effectively.

These challenges show that healthcare improvement requires not only medical services but also coordinated action across government departments, communities and planning institutions.

6. Strategies to achieve SDG 3

The following measures can help governments, local authorities and communities make progress towards the goal.

• Strengthen primary healthcare: Improve local health facilities, diagnostic services, medicine availability and preventive care so that people can receive treatment before conditions become severe.
• Increase public health awareness: Promote health education, vaccination, nutrition, physical activity, disease prevention and mental well-being.
• Improve financial protection: Expand appropriate health coverage and reduce the financial barriers that prevent people from obtaining essential treatment.
• Focus on vulnerable populations: Prioritize maternal and child health, older adults, persons with disabilities, low-income households and underserved communities.
• Integrate health into urban planning: Consider health impacts when planning roads, housing, public spaces, industrial areas, sanitation systems and transport networks.
• Promote road safety: Improve junction design, traffic management, pedestrian crossings, footpaths, cycling facilities and enforcement of road-safety regulations.
• Reduce environmental risks: Control pollution, improve waste management, ensure safe drinking water and strengthen sanitation infrastructure.
• Strengthen healthcare personnel: Improve training, recruitment, retention and the distribution of health workers, especially in underserved areas.
• Use technology and data: Apply GIS mapping, health information systems and spatial analysis to identify service gaps, monitor disease patterns and support evidence-based decisions.
• Improve emergency preparedness: Strengthen disease surveillance, early-warning systems, emergency response plans and the resilience of healthcare facilities.

7. Monitoring and indicators of SDG 3

Progress towards SDG 3 is measured through indicators that assess health outcomes, healthcare access and the capacity of health systems. The United Nations maintains the official SDG indicator framework, while the World Health Organization provides health-related data and monitoring resources.

Indicator	What it measures
Maternal mortality ratio	Maternal deaths per 100,000 live births
Neonatal mortality rate	Deaths during the first 28 days of life per 1,000 live births
Under-five mortality rate	Deaths before the age of five per 1,000 live births
Communicable disease indicators	Measures relating to HIV, tuberculosis, malaria and other specified diseases
Premature mortality from non-communicable diseases	Risk of dying prematurely from specified major non-communicable diseases
Universal health coverage	Access to essential health services and related financial protection
Road traffic mortality rate	Deaths resulting from road traffic injuries
Environmental health indicators	Deaths and illnesses associated with air, water and other environmental pollution
Health workforce indicators	Availability and distribution of healthcare professionals
Emergency preparedness indicators	Capacity to detect and manage health emergencies

8. Conclusion

Sustainable Development Goal 3 is essential for achieving sustainable development because health influences every aspect of human life, including education, employment, economic security and social participation. Its focus extends beyond treating illnesses to preventing disease, promoting mental well-being, protecting mothers and children, reducing environmental health risks and ensuring access to affordable, quality healthcare.

Achieving SDG 3 by 2030 requires coordinated efforts from governments, healthcare institutions, local authorities, communities and individuals. For urban and regional planners, this means designing settlements that provide equitable access to healthcare, safe mobility, clean environments, sanitation and recreational spaces.

Ultimately, a healthy population is both a foundation and an outcome of sustainable development. Progress towards SDG 3 depends on building communities in which everyone has a fair opportunity to live a healthy and fulfilling life.
