2. Introduction
Economic activities provide goods, services, employment and income. However, production and consumption can also place pressure on natural resources and the environment.
A green economy seeks to improve human well-being and economic opportunities while reducing environmental risks and ecological damage.
A green economy is an economy that aims for improved human well-being and social equity while significantly reducing environmental risks and ecological scarcities.
In simple words, a green economy tries to answer an important question:
3. Traditional Economic Activity vs Green Economy
| Conventional Approach | Green Economy Approach |
|---|---|
| May focus heavily on short-term production and consumption. | Considers economic, social and environmental outcomes. |
| May use resources inefficiently. | Promotes efficient use of materials, water and energy. |
| Can generate significant pollution if environmental impacts are not controlled. | Seeks to prevent and reduce pollution. |
| May depend heavily on finite resources. | Promotes resource efficiency, circular practices and suitable renewable resources. |
| Environmental costs may not be fully considered in decisions. | Environmental and social impacts are incorporated into planning and decision-making. |
4. Three Dimensions of a Green Economy
💰 Economic
Supports productive economic activity, innovation, investment and employment.
👥 Social

6. Why is a Green Economy Important?
A green economy is important because economic development and environmental protection are closely connected. Healthy ecosystems provide resources and services that economies depend upon.
🌍 Protects the Environment
Cleaner production and responsible resource use can reduce pollution and environmental degradation.
💧 Conserves Resources
Efficient use of water, energy and raw materials reduces pressure on natural resources.
⚡ Promotes Clean Energy
Investment in energy efficiency and appropriate renewable energy can reduce dependence on fossil fuels.
👷 Creates Green Jobs
New economic activities can create employment in clean energy, waste management, environmental services and other sectors.
💡 Encourages Innovation
Environmental challenges can stimulate new technologies, products, services and business models.
👨👩👧 Supports Well-being
Cleaner surroundings, efficient infrastructure and resilient communities can improve quality of life.
7. Resource Efficiency
Resource efficiency means obtaining greater value or useful output from fewer natural resources while reducing waste and environmental impact.
Examples
- Using energy-efficient electrical equipment.
- Reducing water loss in agriculture and industry.
- Designing products that use fewer raw materials.
- Repairing and reusing products.
- Recovering useful materials from waste.
- Improving industrial processes to reduce material losses.
A factory that produces the same quantity of goods while consuming less electricity and raw material has improved its resource efficiency.
8. Green Economy and Energy
Energy production and use are major parts of economic activity. A greener economy therefore places considerable emphasis on energy efficiency and reducing greenhouse-gas emissions.
Energy Efficiency
- Efficient appliances.
- Energy-efficient buildings.
- Efficient industrial equipment.
- Better public transport systems.
Renewable Energy
- Solar energy.
- Wind energy.
- Hydropower.

| Broad framework for balancing social, economic and environmental needs. | Focuses particularly on transforming economic activity to improve well-being while reducing environmental risks. |
| Includes social equity and intergenerational considerations. | Includes green investment, resource efficiency, clean technologies and green employment. |
14. Inclusive Green Economy
The transition to a greener economy can change industries, occupations and patterns of investment. It is therefore important that the transition considers workers, communities and vulnerable groups.
🎓 Skills
Workers may need training and reskilling for emerging green occupations.
👷 Employment
New green sectors can create employment opportunities.
⚖️ Fairness
Policies should consider communities and workers affected by economic transitions.
