What Sustainability Indicators Exist Now and Should be Used?

Sustainability indicators are key tools for measuring the balance between economic growth, environmental health, and social well-being. They help businesses, governments, and organizations track progress toward sustainability goals, identifying areas for improvement and ensuring that development meets the needs of the present without compromising the future.

In this article we dive into the most critical sustainability indicators and their relevance across sectors.

What Are Sustainability Indicators?

Sustainability indicators are measurable variables that provide insights into the sustainability performance of a system. They are divided into three main categories:

  1. Environmental Indicators: Measure the impact on ecosystems, biodiversity, and natural resources.
  2. Social Indicators: Assess the social well-being, including health, education, and equity.
  3. Economic Indicators: Focus on financial sustainability, including economic growth, employment, and income distribution.

Key Environmental Sustainability Indicators

  1. Carbon Footprint: Tracks the total greenhouse gas emissions caused by an entity, helping to evaluate the climate impact. A lower carbon footprint indicates progress toward reducing global warming.
  2. Water Usage: Measures the amount of water consumed by an organization or process. Efficient water management is crucial for sustainability, particularly in regions facing water scarcity.
  3. Energy Efficiency: Looks at the amount of energy consumed relative to output. Using like solar or wind and reducing energy waste are key strategies for improving this indicator.
  4. Biodiversity Loss: Quantifies the decline in species diversity and abundance. Healthy biodiversity ensures ecosystems remain resilient and productive.
  5. Waste Generation and Recycling: Tracks the amount of waste produced and how much is recycled. High rates and low waste generation signify a commitment to a circular economy.

Social Sustainability Indicators

  1. Access to Education: Assesses the availability and quality of education for all age groups. Education empowers individuals and leads to improved social and economic outcomes.
  2. Healthcare Access and Quality: Measures the availability and quality of healthcare services, including life expectancy and infant mortality rates. Health is a foundational element of societal well-being.
  3. Gender and Income Equality: Tracks disparities in income and opportunities between genders and different socio-economic groups. Reducing inequality fosters social cohesion and economic resilience.
  4. Labor Rights and Employment: Evaluates the quality of employment conditions, such as fair wages, job security, and safe working environments. Decent work is essential for a sustainable and inclusive economy.
  5. Community Engagement: Looks at the involvement of individuals in decision-making processes at local and national levels. Active community engagement supports better governance and accountability.

Economic Sustainability Indicators

  1. GDP Growth and Sustainability: Measures overall economic growth, but when assessed through a sustainability lens, it also considers whether this growth is inclusive and environmentally responsible.
  2. Green Investment: Tracks investments in sustainable technologies and practices, such as renewable energy, eco-friendly , and sustainable agriculture. The more resources allocated to these areas, the more sustainable an economy becomes.
  3. Debt Sustainability: Assesses whether a nation’s or company’s debt levels are manageable in the long term. Over-reliance on debt can undermine future financial stability.
  4. : Measures how efficiently natural and human resources are utilized. Sustainable use of resources is crucial for long-term economic viability.
  5. Employment Rates and Job Creation in Green Sectors: Tracks the number of jobs created in industries like renewable energy, sustainable construction, and eco-tourism. These sectors play a crucial role in transitioning to a low-carbon economy.

To provide a broader view, many organizations use composite sustainability indicators, which combine various individual metrics. Some of the most recognized include:

  1. The Human Development Index (HDI): Combines life expectancy, education, and income per capita to assess overall societal progress.
  2. The Environmental Performance Index (EPI): Assesses how well countries are managing their environmental responsibilities, focusing on air quality, water, biodiversity, and climate change.
  3. The Social Progress Index (SPI): Measures social and environmental outcomes such as health, education, personal rights, and sustainability.
  4. Goals (SDGs) Index: Tracks progress across the 17 United Nations’ SDGs, covering issues from poverty eradication to .

Why Sustainability Indicators Matter

Sustainability indicators are essential for understanding how well societies, businesses, and governments are addressing the environmental and social challenges of the 21st century. They offer transparency, highlight areas for improvement, and create accountability for progress toward sustainability goals. Organizations and nations that focus on improving these indicators are better positioned for long-term success, resilience, and growth.

Moreover, by utilizing these metrics, businesses can better communicate their sustainability efforts to consumers and stakeholders. For investors, these indicators also help assess the long-term viability of companies, particularly as sustainability factors increasingly influence financial performance.

Here’s some relevant data on global sustainability indicators, providing insights into current trends and progress in various sectors:

1. Carbon Footprint

  • Global CO2 Emissions: In 2022, global carbon dioxide emissions reached approximately 36.8 billion metric tons, an increase of around 0.9% from 2021, largely due to the recovery from pandemic-related slowdowns in industrial activity (IEA, 2023).
  • Top Emitters:
    • : 10.06 billion metric tons (27.5% of global emissions).
    • United States: 4.7 billion metric tons (13.9% of global emissions).
    • European Union: 2.3 billion metric tons (6.8% of global emissions).

2. Water Usage

  • Global Freshwater Withdrawals: Agriculture accounts for about 70% of global freshwater withdrawals, with industrial use at 20% and municipal use at 10% (FAO, 2022).
  • Water Scarcity: Approximately 2.2 billion people worldwide lack access to safe drinking water, and by 2025, half of the world’s population may live in water-stressed areas (UNICEF, 2022).

3. Energy Efficiency

  • Global Renewable Energy Share: Renewables accounted for 29% of global electricity generation in 2022, with wind and solar leading the way (IEA, 2023).
  • : The global primary energy consumption in 2022 was 595 exajoules, a 1.3% increase from the previous year. Non-renewable sources (oil, coal, natural gas) still dominate energy consumption, with 79% of the total share.

4. Waste Generation and Recycling

  • Global Municipal Solid Waste: The world generated approximately 2.24 billion tons of municipal solid waste in 2022. Of this, only 19% was recycled, while 37% was landfilled, and 11% incinerated (, 2023).
