Outline

• Theory of offsets• How offsets could support biochar projects• Methodology issues• Current funding from The Climate Trust

Source: The McKinsey Quarterly. 2007. “A cost curve for greenhouse gas reductions.”

US Offset Market

• Trends–Fossil fuels will likely be capped–Favor domestic projects over international projects

• Destroying methane emissions• Sequestration

– Forestry– Soil Management– Biochar?

Sequestration Projects• Clean Development Mechanism

– Reforestation/afforestation only– Temporary credits

HFCs, PFCs & N2O reduction27%

Renewables35%

CH4 reduction & Cement & Coal mine/bed20%

Supply-side EE10%

Fuel switch6%

Demand-side EE1%

Afforestation & Reforestation0.4%

Transport0.2%

Expected CERs Until 2012 (%) in each category

$ = CO2 Sequestered x Price• Low Quality US Projects

• Chicago Climate Exchange: $2-$4/mt CO2

• High Quality US Projects

• Voluntary Carbon Standard: $4-$9/mt CO2

• California Climate Action Registry: $5-$11/mt CO2

• Mature International Markets

• EU Emissions Trading Scheme: $10-$40/mt CO2

• Projections for Early US Market

• Markey-Waxman Bill : $10-$15/mt CO2

GHG Reduction Reduction Size Qualify for Carbon Finance?

Sequestration Large Yes

Fuel switch Medium Likely to be capped

Less fertilizer fewer soil emissions(N2O and CH4)

Medium/Large Hard to measure

Less fertilizer less fertilizer production

Small/Medium Indirect, hard to measure, likely to be capped

Biochar GHG Reductions

Currently Methodologies

Avoidance of methane production from biomass decay through controlled pyrolysis

• Small scale• No credit for carbon sequestration, but…• Char must be “biologically inert”

• Volatile C/Fixed C ratio lower than 50%

Next Step: Sequestered Carbon

Carbon Gold methodology for proposed to the Voluntary Carbon Standard

Outline

• Theory of offsets• How offsets could support biochar projects• Methodology issues• Current funding from The Climate Trust

Unresolved Methodology Issues

• Recalcitrance• Guarantee 100 years of permanent sequestration

• Carbon Gold: Volatile C/Fixed C ratio lower than 50%

• Soil monitoring• What happens to char that erodes out of the soils?

Unresolved Methodology Issues

• Ownership – Three entities, same reduction1. Feedstock owner 2. Pyrolysis plant3. Land owner

• Carbon Gold: Credits pyrolysis plant• Sequestered carbon can only be claimed once

Unresolved Methodology Issues

• Environmental impact– Heavy metals– Criteria air pollutants– Microbe health– Carbon already in soil

Resolved Issue: Waste Feedstocks

• Leakage– Changes in emissions outside the project

itself• Direct: Biomass fuel unavailable• Indirect: displace current farm land for biochar

feedstock plantations land use change• Carbon Gold: “biomass that would otherwise

have been left to decay or been burned in an uncontrolled manner”

Outline

• Theory of offsets• How offsets could support biochar projects• Methodology issues• Current funding from The Climate Trust

• 3 Programs• Oregon Program• Smart Energy• Colorado Carbon Fund

• 16 projects, $8.8 million in funding, 2.6 million tons of CO2 offset

• Non-profit

- Laboratory for innovative offset projects
