Five glowing laboratory flasks on a dark bench at night: yellow, cyan, green, gold, and blue reagents, with vapor rising into network diagrams and a green city

Solutions
Each card pairs a planetary problem with a technology already in use. Filter by topic, then follow the sources.
Photo: founder-supplied laboratory reagent bottles.
Water
Harvesting, reuse, desalination, leak control, disinfection, recharge, and living filters already in use.
Forests
Regeneration, agroforestry, careful logging, and fire-smart practice that keep forests working. Also here: forest certification, payments for reduced deforestation and forest degradation, closer-to-nature forestry, enrichment planting in logged forest, and mass timber for buildings.
Waste
Sorting, recycling, organics, and energy recovery already running at municipal scale. Five ways to reduce waste and recover materials: deposit-return systems for drinks containers, extended producer responsibility for packaging, collection and recycling of electronic waste and lithium-ion batteries, and ways to stop edible food from being thrown away.
Cities
Cooler roofs, permeable streets, trees, and shared heat networks. Also here: how people move and the air they breathe, from bus rapid transit, walking and cycling networks and congestion charging to low-emission zones and electric buses.
Materials
Cement, metals, timber, and recycled building materials already cutting embodied carbon.
Oceans
Catching plastic, restoring shores, fishing with less bycatch, plus protected areas, ship rules, and water-column farms.
Energy
Wind, solar, hydro, nuclear, storage, and heat already running on real grids.
