“Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
— United Nations Brundtland Commission, Our Common Future (1987)
Carbon Emissions
The amount of carbon dioxide in the atmosphere is now 50% higher than it was before the Industrial Revolution, leading to a record high of 422.8 parts per million (ppm) in 2024.
Energy
The consumption of energy is the dominant contributor to climate change, accounting for about two-thirds of total global greenhouse gas emissions. The world continues to rely heavily on fossil fuels, even with the rapid growth of renewables.
Waste
Around 75% of all waste can be recycled, yet the annual global recycling rate is much lower. This gap represents a significant opportunity to conserve resources and reduce landfill waste.
Water
Globally, water consumption has increased at more than twice the rate of population growth over the last century, putting immense pressure on freshwater resources and leading to scarcity in many regions.
Materials/Resources
Humanity's demand for natural resources has reached a point where we are using the equivalent of 1.6 Earths to maintain our current lifestyles, a rate that is unsustainable for the long term.
Biodiversity
Despite covering only 5% of the planet's land area, forests are home to over 80% of the world's terrestrial species, making them critical to global biodiversity.
