Product-as-a-service models (leasing and performance contracts instead of ownership)

Industry is the backbone of modern civilization, but it's also one of the biggest sources of greenhouse gas emissions. Manufacturing steel, cement, chemicals, and plastics doesn't just burn fossil fuels for energy — these processes often require fossil fuels as raw ingredients or release CO2 as an unavoidable part of the chemistry itself.

This creates a massive challenge. We can't simply swap in renewable electricity and call it solved. Heavy industry needs fundamentally different approaches: new chemistries, new materials, new ways of thinking about how we make things. The scale is enormous — industry accounts for about a quarter of global emissions — but so is the opportunity to transform how we build our world.

Our economy is built on a take-make-waste model: extract raw materials, make products, use them briefly, then throw them away. This linear approach wastes enormous amounts of materials and energy while creating mountains of waste. Most products are designed to be cheap and disposable rather than durable and repairable.

A circular economy keeps materials in use as long as possible, then recovers and regenerates them at the end of their service life. This requires fundamentally rethinking how we design, make, and use products. The potential is enormous — circular economy approaches could reduce global emissions by 45% while creating new business opportunities and reducing waste.

Instead of selling products, companies provide the service the product delivers. Customers pay for lighting instead of buying light bulbs, or mobility instead of owning cars. This gives companies incentives to make products that last longer and perform better, since they retain ownership and responsibility. It also makes advanced, efficient products accessible to customers who couldn't afford to buy them outright.
