Goal: Offset 475 Tons of Emissions

The scientific evidence is clear: our global climate is warming due to the presence of increasing amounts of greenhouse gases in our atmosphere. Public and political awareness of the consequential dangers have been increasing and it is very fitting that the 2007 Nobel Peace Prize was awarded to the Intergovernmental Panel on Climate Change and local Tennessean Al Gore "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change". The challenge to address global climate change is perhaps the greatest of our time. For everything we do we should always consider alternative ways that may lessen our climate and environmental impact.

We therefore hope that members and sponsors of the ACA will join our effort to make the 2008 meeting Climate Neutral. We cannot prevent all greenhouse gas emissions, but we can ensure that the net result of our activities decreases rather than increases the amount of CO2 in the atmosphere. This goal can be achieved by offsetting the CO2 released as a consequence of attendees and vendors flying to the meeting and use of the conference center and hotels. We plan to do this by continuing the campaign begun last meeting. We have selected the national Carbonfund organization to make the ACA 2008 annual meeting a CarbonFree event. is dedicated to fighting climate change, making it easy and affordable for any person or organization to eliminate their climate impact and hastening the transformation to a clean energy and technology future. They work to achieve this by providing climate change education and cost-effective solutions to carbon reductions that include saving energy and carbon offsets.

The ACA 2008 Climate Neutral Campaign will use the carbon offsets program of to help compensate the CO2 emissions associated with this meeting. Our purchases of carbon offsets will support three types of carbon offset projects: renewable energy, energy efficiency, and reforestation. While each is different, they all play an important role in the fight against climate change. All of's offset obligations are matched against projects that meet or will meet the Climate, Community and Biodiversity Alliance (CCBA), Environmental Resources Trust (ERT), or United Nations Framework Convention on Climate Change (UNFCCC) Joint Implementation (JI) standards. Detailed information on the different types of carbon offset can be found at the website.

Preliminary estimates indicate that to make our ACA 2008 meeting Climate Neutral we will need to offset 475 tons of emissions or approximately 1600 lbs for every attendee (84% of the emissions are travel, the remainder hotel, venue and meals). On average an individual campaign purchase $4 of carbon offsets per attendee will allow us to reach our goal. After completiion of the ACA 2008 meeting registration, contributions can be made on this web page which is setup to collect and track the effectiveness of this campaign. This campaign is also an effective mechanism to mitigate other sources of emission. For example, electricity used by an average university worker ($30/year), an average US household's electricity ($30/year), an average US family's total direct fossil fuel use, excluding air travel, ($90/year).

We hope that you will join our efforts to make the 2008 ACA Knoxville meeting a Climate Neutral event.
