The meaning of sustainable economic growth

Sustainable economic growth refers to an increase in a country's output that can be maintained over the long term without depleting resources or harming future generations. It involves balancing economic expansion with social and environmental considerations to ensure ongoing progress.

This type of growth supports lasting improvements in living standards, such as better access to education, healthcare, and infrastructure, while avoiding short-term gains that lead to long-term damage.

Key concepts in resource management

Scarcity and choice:

• Resources are limited, so decisions must be made about how to allocate them effectively between current and future needs.

Renewable and non-renewable resources:

• Renewable resources, like forests or solar energy, can replenish naturally but may become non-renewable if overused.
• Non-renewable resources, such as oil or coal, are finite and cannot be replaced once exhausted.

Economic growth can sometimes enhance environmental conditions by funding cleaner technologies, such as renewable energy sources, or supporting conservation efforts that protect ecosystems.

Benefits and arguments for using or conserving natural resources

Exploiting natural resources can drive economic growth in the short term, but conservation offers long-term advantages. Decisions on resource use often weigh immediate economic benefits against future sustainability.

Short-term benefits of using natural resources

• Job creation and increased output - Extracting resources like minerals or timber generates employment and boosts production levels.
• Improved trade position - Exporting resources strengthens the current account by increasing foreign earnings.
• Revenue for development - Taxes from resource extraction can fund investments in infrastructure, education, and public services.

Arguments for conserving natural resources

• Boosting tourism - Preserving natural areas attracts visitors, creating alternative income sources.
• Environmental protection - Maintaining ecosystems helps absorb carbon dioxide and supports biodiversity.
• Future availability - Saving resources ensures they are accessible for later generations.
• Potential for higher future value - Resources may fetch better prices in the future due to increased scarcity or demand.

For example, between 2007 and 2013, Ecuador's government attempted to secure international funding to avoid extracting oil from the Yasuni National Park in the Amazon rainforest, aiming to protect the environment and biodiversity, though the initiative did not succeed.

Factors influencing resource use decisions

Governments and businesses consider various elements when deciding whether to exploit or conserve resources. These factors help balance short-term gains with long-term sustainability.

Key influences on resource management choices

• Predictions of future demand - If demand is expected to rise, conservation might allow for higher future profits.
• Type of resource - Renewable resources may be used more freely, while non-renewable ones require careful management to avoid depletion.
• Comparative advantage - Countries assess if extracting resources now provides a trade edge, or if waiting could offer greater benefits later.
• Current economic situation - Issues like high national debt may push for immediate resource use to generate quick revenue.

Environmental impacts of economic growth

Economic growth often leads to negative environmental effects across different sectors, though targeted policies can help mitigate these issues.

Impacts by economic sector

• Primary sector - Activities like farming release methane from livestock, cause deforestation, emit gases from fertilisers, lead to overfishing, and pollute through mining.
• Secondary sector - Manufacturing and energy production generate greenhouse gases from factories and fossil fuel consumption.
• Tertiary sector - Services contribute through transport emissions and the destruction of natural habitats for infrastructure.
• Consumption - Everyday use results in vehicle pollution, household waste, and plastic contamination of oceans and land.

Policies to mitigate environmental impacts and their advantages and limitations

Governments use various tools to reduce the environmental harm caused by economic growth. Each policy has strengths and weaknesses, influencing its effectiveness in promoting sustainability.

Types of environmental policies

• Subsidies for clean alternatives - Financial support for renewable energy or conservation projects encourages eco-friendly practices.
• Information provision - Using nudge theory to educate and influence behaviour, such as campaigns promoting recycling.
• Legislation - Laws that ban or restrict harmful activities, like prohibiting certain pollutants.
• Environmental taxes - Charges based on the polluter pays principle, where those causing damage pay more.
• Tradable pollution permits - Systems where firms buy licenses to emit a limited amount of pollutants, with the option to trade them.
