Intent of credit: ---- Reduce operations related carbon footprint and encourage organizations associated with LEED projects to do likewise. Requirements for compliance: ---- Identify operational sources of carbon emissions not otherwise addressed by LEED. Establish the operational carbon footprint of the occupants of the LEED project verified by a recognized authority. (See CIR dated 6/29/06 for list of authorities). Obtain carbon offsets for the carbon footprint associated with operational sources of carbon emissions equal to or greater than 50% over 2 years**. Submittals: ---- 1. Signed letter template declaring that offsets equivalent to at least 50% of operational carbon emission loads associated with air travel, car travel, and natural gas for a period of at least two years have been obtained. 2. Narrative describing the project\'s approach to addressing carbon loads. 3. Calculation used to determine carbon emissions, resulting equivalence data, and quantity of offset measures required. 4. Certification document from a recognized source of carbon offset credits. Design Approach (Strategies) / Narrative: ---- Reliable analysis of construction related life cycle carbon emissions is difficult to obtain and verify at this time. Emissions data related to operations are more readily available and recognized authorities exist that can quantify the carbon emissions related to operations based on established metrics. This credit addresses carbon emissions other than those addressed by LEED-CI v2.0 EAc4 Green Power. The following steps describe the actions needed to achieve this credit: Research currently available carbon emission measurement standards and offset options. Identify recognized service providers. (See CIR dated 6/29/06 for list of recognized authorities) List carbon emission sources specific to operations associated with the project in question. Run calculations on offset measures needed. Obtain carbon offset credits at least equivalent to 50% of operational carbon emission loads associated with natural gas, air travel, and car travel for a period of at least two years. This innovation credit meets the three basic criteria for innovation credits as described in the LEED Reference Guide: 1. Quantitative performance improvement: A baseline evaluation of the operational carbon footprint using methods specified by a recognized authority (Green-e for instance) establishes a starting point and is used to calibrate the quantity of carbon offset measures needed. 2. Comprehensive program: The program addresses business related carbon emissions related to air travel, car travel, and natural gas, not covered by LEED and augmenting similar efforts related to electrical loads achieved by meeting LEED-CI v2.0 EAc4 Green Power requirements. 3. Applicability to other projects: This innovation credit provides an outline for any organization interested in addressing their operational carbon footprint. Similar ID credits related to post occupancy efforts are listed in the USGBC\'s Innovation & Design Credit Catalog (1 December 2007), including credits addressing: Green Cleaning; Monitoring Threatened & Endangered Species; Donation and Protection of Open Space (not assoc. with project site); Alternative Transportation Management Plan; Employee Reduction of Greenhouse Gas Emissions; Food composting; Occupant recycling program; Waste reduction operations; Work at home program; LEED post-occupancy performance evaluation; Employee wellness; Educational program; Student report; Carbon offset; Environmentally preferable services; and Off site environmental benefit. ** Time period and % based on those established for the LEED-CI v2.0 EAc4 Green Power credit.
The applicant submitted a CIR proposing an innovation and design credit in which projects would offset the emissions associated with tenant space operations. While this proposal does demonstrate environmental benefits, it cannot be approved at this time due to the complexities surrounding carbon accounting. USGBC is performing research in this area and will update this CIR ruling as necessary. Applicable Internationally.
