16. Microwaves often use less energy than standard ovens
For small meals and reheating, microwaves provide a quick, energy-efficient option, reducing overall electricity use in the kitchen.
Consumption & Waste Facts
17. Food waste accounts for 8-10% of global GHG emissions
This staggering amount of greenhouse gas emissions highlights the need for better food management. This includes the need for systems that prevent waste at every level, from farms right through to households.
18. Recycling one ton of paper is better than you know
Recycling a ton of paper can save 17 trees and 7,000 gallons of water! This comes down to avoiding the turnover of monoculture tree plantations, growth to provide virgin paper. Smart recycling practices benefit natural resources by conserving forests and reducing the water footprint of paper production processes.
19. Fast fashion causes 10% of global carbon emissions
Production of high volume, cheap clothing demands a lot energy throughout the production process. Additionally, the rapid turnover of clothing not only floods landfills with waste, but also burdens the environment with excessive resource extraction and pollution from dyes.
20. One cotton T-shirt can consume up to 2,700 litres of water
This water-intensive process is a major drain on available resources. Consider higher quality, sustainable fashion, sources where possible to limit your contribution to this water demand.
21. Electronic waste is the fastest-growing global waste stream
E-Waste volumes hit 62 million tonnes globally in 2022. This is projected to reach 80 million tonnes by 2030! With rapidly advancing technology, ensuring proper recycling and disposal of old devices is critical to prevent environmental contamination.
22. Glass is infinitely recyclable without quality loss
Unlike many materials, glass can be recycled repeatedly, making it a sustainable packaging choice when managed effectively.
23. Your plastic bag will outlast you by centuries
A single plastic bag is typically used for around 12 minutes yet can last centuries in a landfill. This discrepancy emphasises the importance of choosing reusable alternatives to minimise long-term environmental damage.
24. Plastics in oceans may out-weight fish by 2050
Much of this waste is released from land sources, via 10 of the world’s major rivers. These plastics even find there way into all organisms, from microscopic forms, through to the great whale species roaming the oceans.
Food & Agriculture Facts
25. Locally sourced food typically cuts down on carbon emissions, but not always
Supporting local producers not only boosts regional economies but also provides fresher, seasonal produce with a lower environmental footprint. It is though not always the case! For example, its possible that food grown locally, but out of season, could have a very high footprint due to the additional energy needed for heat and light.
26. Agriculture uses 70% of global freshwater
Most of the world’s freshwater is used for growing crops and raising animals, not for drinking or washing.
27. Crop diversity is in decline
Crop diversity declined 75% in the 20th century, and that trend continues today with modern agriculture relying on just a few crops. Consequently, resilience to pests and vulnerability to climate change are major risks to production.
