THOUSAND TONS OF CO₂E EMISSIONS
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.
Low CO2e Fuel Is Needed for Aviation 
Efficiency gains in airplane design are not able to offset the rise in emissions due to increased transit demand. A low-carbon fuel solution is needed to deliver significant emissions reductions.

Air Travel Is Major CO2e Source
The aviation industry is responsible for an estimated 3%, or 1.5 billion tons, of annual anthropogenic CO2e emissions. At its current growth rate, the IPCC estimates that the industry will be responsible for over 5% of emissions by 2020.

Transport Energy Use Is Rising
Reliance on petroleum, which supplies approximately 95% of transport energy, is driving CO2e emissions growth in the transport sector at a dangerous rate.
Aviation Accounts for 7% of U.K. Emissions
Aviation emissions are a significant portion of total emissions; in the U.K., aviation is estimated to contribute 7% of total CO2e emissions.

Transport Emissions Are Rising
Under business-as-usual, transport emissions continue to increase dramatically and are a major contributor to rising CO2e levels that lead to catastrophic climate change.
