Atmospheric concentrations of CO₂e are rising due to increasing anthropogenic emissions. Unchecked, rising concentrations of CO₂e in the atmosphere will lead to catastrophic climate change.

Public electricity and heating in Annex I countries accounted for over 6.68 billion tons of CO₂e emissions annually in 2007.

Transport is responsible for approximately 20% of global anthropogenic emissions, or more than 4.63 billion tons of CO₂e annually. Source: UNFCCC, 2009.

Buildings are responsible for an estimated 1.45 billion tons of CO₂e in Annex I nations and over 20% of global anthropogenic emissions annually. Source: UNFCCC, 2009.

Annex I industry emissions are over 1.3 billion tons of CO₂e annually. Global industry emissions account for approximately 24% of annual anthropogenic emissions. Source: UNFCCC, 2009.

Emisisons from agriculture in Annex I countries totaled more than 1.43 billion in 2007 CO₂e emissions.

The EIA estimates that 2006 energy-related emissions from non-OECD countries accounted for approximately 30%, of global anthropogenic CO₂e emissions, or 15.4 billion tons. Source: EIA, 2009.

Biochar could potentially remove over 1 billion tons of CO₂e annually. In general, carbon management solutions could remove billions of tons of CO₂e from the atmosphere annually.
