Study Notes
Earth Overshoot Day
- Marks the point in the year when humanity surpasses the Earth's ability to replenish its resources.
- In 2023, it fell on August 2, five days later than the previous year.
- Four of those days are due to the incorporation of new data sets.
Importance of Delaying Earth Overshoot Day
- To achieve the United Nations' target of a 43% reduction in global carbon emissions by 2030, Earth Overshoot Day needs to be pushed back by 19 days each year for the next seven years.
- Persistent overshoot could lead to extreme weather events, compromising food production and causing other environmental issues.
Calculation of Earth Overshoot Day
- Involves assessing factors such as the planet's available resources and humanity's consumption demands, including food, timber, and urban space.
- The Global Footprint Network determines Earth Overshoot Day by dividing the Earth's biocapacity by humanity's ecological footprint and multiplying the result by 365 days.
Country Overshoot Days
- Similar calculations are conducted on a country-by-country basis to determine Country Overshoot Days.
Trend of Earth Overshoot Day
- Since data collection began in 1970, Earth Overshoot Day has been occurring earlier and earlier each year.
- This means that humanity is consuming nature's renewable resources in just over half a year, resulting in an ecological deficit for the rest of the year.
#MoveTheDate Campaign
- Aims to highlight the potential for reversing current consumption trends and improving our quality of life.
- Focuses on five areas of change: planet, cities, population, energy, and food.
- Measures such as increasing low-carbon electricity sources and reducing food waste can significantly impact the date of Earth Overshoot Day.
