How do we remove this COHow do we remove this CO22??
• 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 CO2 emissions deep into geological subsurface

What is a carbon footprint?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
