Sonoma-Loeb Chardonnay 2007 Greenhouse Gas Inventory

Offset scope 1, 2 and partial 3 emissions for this by bottle by supporting replanting and maintaining efforts of redwood forests in clear-cut tracts in Humboldt County, California. Calculations are based on The Climate Registry General Reporting Protocol and the International Wine Calculator.

Emission estimate: 490 metric tons carbon dioxide equivalent (MTCO2e)
Emissions offset by purchasing forestry credits: 530 MTCO2e

Offset Project Details:

The Van Eck Forest Project is a Conservation-Based Forest Management project on 2,200 acres of native redwood forest in Humboldt County, California in an area undergoing significant land-use change and development pressure. The project will permanently reduce more than 500,000 tons of CO2e over a 100-year period. A working forest conservation easement on the project ensures the land's carbon stores are permanent and will never be lost to development or land use conversion. The easement also guides sustainable management of the forest to enhance forest carbon stores, achieving considerable gains in CO2 sequestration relative to business-asusual practices. In addition to helping cool the climate, the project helps protect wildlife habitat for threatened species such as the Northern Spotted Owl. It also helps safeguard clean water supplies and restores biodiversity and oldgrowth qualities while continuing to provide sustainably harvested wood products and jobs to the local community.

The "Working Forest" carbon offset represents the increased carbon stock resulting from the protection and stewardship of a mature forest, the avoidance of carbon stock depletion and deforestation and the increase in standing forest volume over time.

The project is registered with the California Climate Action Registry (CCAR). The project is the first emissions reduction project registered and independently verified under the CCAR's Forest Protocols - the rigorous accounting standards California has adopted to meet its ambitious greenhouse gas reduction goals.

Reporting year: 2007

Type: Transitional Reporter


Organizational boundary:
Equity share approach:
Office: 100%
Winery: 13% equity share


The equity share of Sonoma-Loeb's Chardonnay label is based on the emissions resulting from two locations. Office related emissions were 100% equity share control while wine production at the winery amounted to 13% in. Emissions resulting from vineyard activities or operations were not considered as Sonoma-Loeb has no equity share control over them.

Operational boundaries:

Scope 1/direct emissions - stationary
New York Office (natural gas from heating): Natural gas: 1.4 MTCO2e

Scope 2/indirect emissions
New York Office: 3.27 MTCO2e
Electricity Usage: Square footage and number of employees were provided and EIA energy intensity data used to extrapolate fuel usage.

Scope 3/indirect emissions
Employee Flights: 3.30 MTCO2e
Waste treatment: 0.30 MTCO2e
Winemaking Practices: 7.30 MTCO2e
Biomass Photosynthesis: -41.06 MTCO2e
Packaging: 81.95 MTCO2e
Transport (Distribution): 46.21 MTCO2e
Vineyard Practices: 367.83 MTCO2e
Purchased Wine Products: 0.04 MTCO2e
Purchased Electricity Winery: 17.88 MTCO2e
Stationary combustion at winery: 1 MTCO2e
Emergency generators (diesel): 0.8 MTCO2e
High powered washer (kerosene): 0.14 MTCO2e
Mobile combustion at winery: 0.6 MTCO2e
Dump Truck: 0.002 MTCO2e
Dodge Ram 2500: No information.
Propane forklift: 0.24 MTCO2e
Each delivery of propane was in the #33 standard tanks which hold 7.9 gallons each (Propane 101 website).
Diesel forklift & Diesel tractor: 0.34 MTCO2e
Diesel stored in the tanks was initially indicated to be used for the emergency generator, a forklift, and a tractor. In the inventory, 265 gallons was split only between a forklift and a tractor, due to inconsistencies with the frequency the generator was run and assumptions with the amount of fuel that would be needed.
