World Resources Institute Annual Carbon Dioxide (CO2) Inventory Report Fiscal Year 2002

WRI's fiscal year 2002 CO2 emissions were 1,306 metric tons, representing a 3.5% reduction from 2001. The primary emission sources were purchased electricity (42%) and air travel (40%). While air travel emissions have decreased to 1% below 2000 levels, electricity emissions have risen 24% since 2000, largely due to increased cooling requirements from another tenant in WRI's non-separately metered building. WRI has adjusted historical data using improved methodologies and now holds a surplus of carbon offsets. To maintain its commitment, WRI is exploring new ways to fund offsets and has published the 'Working 9 to 5 on Climate Change' guide to help other organizations reduce their footprints.

• WRI's total CO2 emissions for fiscal year 2002 were 1,306 metric tons, which is a 3.5% decrease compared to 2001.
• The two largest contributors to WRI's 2002 emissions were purchased electricity, accounting for 42% (535 metric tons), and air travel, accounting for 40% (529 metric tons).
• Electricity emissions have increased by 24% since 2000, primarily because WRI's office is not separately metered and a large tenant in the building required increased cooling during summer months.
• Air travel emissions, which rose nearly 12% between 2000 and 2001, have since fallen to 1% below the levels recorded in 2000.
• WRI has adjusted its historical emissions data for 1998-2001 to reflect improved calculation methodologies for air travel and rail travel, and to use power pool emissions factors for electricity due to the deregulation of the DC electric market.
• Due to the downward adjustment of historical emissions, WRI currently possesses a surplus of carbon offsets, having previously purchased offsets to meet its net zero goal early.
• WRI recommends changing its base year from 1990 to 2000 because the 1990 activity data is incomplete, making comparisons less meaningful.
• To support other office-based organizations in reducing emissions, WRI published 'Working 9 to 5 on Climate Change: An Office Guide' in early 2003 and developed accompanying calculation tools.
