III. Solutions for a more sustainable future

Documents

F-gases : Industrial processes, refrigeration, and the use of a variety of consumer products contribute to emissions of F-gases.
Nitrous Oxide : Agricultural activities, such as fertilizer use, are the primary source of N2O emissions. Fossil fuel combustion also generates N2O.

  • Ecological Footprint – Measures how much land, water, and resources a person or country uses compared to what Earth can provide.
  • Carbon Emissions (CO₂ emissions) – The release of carbon dioxide into the atmosphere from human activities like burning fossil fuels.
  • Climate Change – Long-term changes in Earth’s weather patterns caused mainly by human activities.
  • Global Hectare – A unit measuring how much productive land and water area is needed to support one person’s lifestyle.
  • Renewable Energy – Energy from sources that can naturally replenish, like solar, wind, hydro, and geothermal.
  • Fossil Fuels – Non-renewable energy sources like coal, oil, and natural gas that release greenhouse gases when used.
  • Deforestation – The clearing of forests for agriculture, logging, or other human uses, often harming ecosystems.
  • Biodiversity Loss – The decrease in the number of species in an ecosystem, reducing its health and resilience.
  • Sustainable Agriculture – Farming methods that protect soil, save water, and reduce environmental impact, like crop rotation or agroforestry.
  • Energy Efficiency – Using less energy to perform the same task, reducing emissions and costs.
  • Carbon-Negative – Removing more carbon dioxide from the atmosphere than is emitted.
  • Urban Green Spaces – Parks or green areas in cities that improve air quality, reduce heat, and absorb rainwater.
  • Climate Vulnerability – The degree to which a country or community is affected by climate change impacts, regardless of its emissions.
  • Corporate Responsibility – How companies’ actions impact the environment, such as through resource extraction or industrial practices.
  • Sustainable Urban Planning – Designing cities to reduce energy use, encourage green transport, and improve environmental quality.
