What is the avoid, reduce, replace order?

This simple hierarchy helps you pick the right action first:

Step	Question to ask	Example
Avoid	Do I need this at all?	Skip a short-haul flight by holding a video call
Reduce	Can I do it with less energy?	Choose a 5-star appliance, set the AC higher
Replace	Can a cleaner source do it?	Rooftop solar, an electric vehicle on a cleaner grid
Compensate (last)	What is left that I truly cannot cut?	Only then consider credible credits, with honest claims

The IPCC's Sixth Assessment Report (Working Group III, Summary for Policymakers, 2022, section C.10) found that demand-side measures, meaning changes in how people use energy, food and transport, could cut emissions in buildings, land transport and food by 40-70% by 2050 compared with baseline scenarios. That is a global finding about potential, not a promise for any one household.
