Climate change

For an introduction, read What is climate change.

Biggest factors

GHGs (greenhouse gases) (such as CO₂) are the gases that cause climate change. This is a pie chart of where they come from.

Note that half of emissions come from the richest 10% of the world, which includes you if you're middle-class in a developed country. That's the target audience for the "personal actions" section of this page.

Most of the world's emissions are affected by either...

• How much new "stuff" gets made. Template:Pi

• How much people drive/fly. Template:Pi

• Heating & cooling homes and other buildings. Template:Pi

• Food production. Template:Pi

This provides some perspective on the most significant actions to take.

Actions to take

If you think there's anything more significant to add to this list, leave a comment on the talk page.

Personal actions

• Frugalism
• Driving less (or not at all)
• Plant-based food
• Not wasting food

Collective actions ✊🏻✊🏽✊🏿

• Stop planned obsolescence
• Make neighborhoods walkable
• Improve public transit
• Decarbonize energy - but this requires major tech innovations that might not come soon enough.
  • Decarbonization becomes a lot easier if energy consumption is lower - so in any case, the other actions on this page still matter more than ever.

For those who are skeptical

• Why climate change is a problem
• Why climate change is anthropogenic
