Summary of Megatrend 3: Environment & Resources

Core Content

Megatrend 3 focuses on the growing challenges posed by climate change and pollution, as well as the abundance versus scarcity of natural resources and the risk to ecosystems. This megatrend highlights the urgent need for global action to mitigate environmental degradation and its impact on human health and natural systems.

Main Points

1. Climate Change & Pollution

• Climate Change: The natural greenhouse effect maintains Earth's temperature, but the anthropogenic greenhouse effect has significantly increased due to human activities like fossil fuel burning, agriculture, and land clearing.
• Global Warming: The Earth has warmed by 1.2°C since pre-industrial times, with a projected increase of 2.9°C by 2100 under current policies.
• CO₂ Concentration: The concentration of CO₂ in the atmosphere has reached its highest level in at least 800,000 years, with levels well above 400 ppm. CO₂ remains in the atmosphere for a long time, meaning even if emissions stop, its effects will persist for hundreds of years.
• Emission Sources: The energy sector is the largest contributor to greenhouse gas emissions, followed by transportation, industry, and agriculture.
• Global Emissions: In 2018, global GHG emissions totaled 48.9 GtCO₂e, with China responsible for 25%, the US and EU for 12.5%, and India for 7%. The 100 least-emitting countries account for less than 3% of emissions.
• Net Zero Targets: Many countries have set net zero emissions targets, but national laws are still limited. The Paris Agreement aims to limit global warming to well below 2°C, preferably 1.5°C, but current efforts may not be sufficient.

2. Resources: Abundance vs. Scarcity

• Resource Scarcity: The increasing demand for water, food, and raw materials is putting pressure on natural resources, with scarcity becoming a critical issue.
• Economic Growth: As global emissions rise due to industrialization and population growth, the economic cost of pollution is significant, especially in low-income countries.

3. Ecosystems at Risk

• Ecosystem Impact: Climate change and pollution are putting biodiversity and ecosystems at risk. At 2°C of warming, 18% of insects, 16% of plants, and 8% of vertebrates are expected to be affected.
• Sea Level Rise: By 2100, 46-49 million people could be impacted by sea level rise.
• Coral Bleaching: At 2°C, virtually all coral reefs could be lost by 2100.
• Pollution Effects: Pollution, particularly air and water, causes 8.3 million deaths annually and affects human health, animal health, and ecosystem integrity.

Key Information

Pollution and Health

• Air Pollution:
  • 91% of the global population lives in areas with air quality levels exceeding WHO limits.
  • Air pollution is responsible for 1 in 8 deaths worldwide and reduces life expectancy by 2.2 years on average.
• Water Pollution:
  • In developing countries, the number of deaths from unsafe water is declining, but in advanced economies, it is increasing.
  • Water pollution leads to economic losses and health issues.
• Soil Pollution:
  • Causes USD 20 billion in annual agricultural losses in China.
  • Leads to contamination of food and water, affecting human and animal health.
  • Indirect costs include biodiversity loss and ecosystem degradation.

Mitigation Strategies

• Renewable Energy: To achieve net zero emissions by 2050, the use of renewable energy must increase drastically.
• Pollution Reduction:
  • Ban harmful pollutants and set tighter pollution limits.
  • Implement circular economy practices and sustainable products.
  • Improve land use, waste, and light management.
• Global Cooperation: The Paris Agreement is the first universal, legally binding climate agreement, but implementation is uneven, with many countries still lacking national laws to support net zero goals.

Conclusion

The Environment & Resources megatrend underscores the urgent need for global action to combat climate change and pollution, which are major threats to human health, biodiversity, and ecosystem stability. CO₂ is the primary greenhouse gas, and renewable energy and international cooperation are essential for achieving net zero emissions and limiting global warming. Pollution has significant health and economic impacts, and strategies must include regulation, sustainable practices, and technological innovation to mitigate its effects.
