How do we remove this CO 2 ? Carbon sink: is a reservoir of carbon that accumulates and stores carbon for an indefinite period. The main sinks are: –Absorption of carbon dioxide by the oceans –Photosynthesis by plants and algae to turn the carbon into plant matter –Injection of CO 2 emissions deep into geological subsurface

Breakdown

What is a carbon footprint? Carbon footprint (FP): is “the total set of GHG (greenhouse gas) emissions caused directly and indirectly by an individual, organization, event or product” (UK Carbon Trust 2008). Everyone in this room has a FP

Let’s determine your C-FP
