Spatial Informatics Group - Natural Assets Laboratory

The science and policy of natural assets and environmental markets are evolving rapidly and require nimble institutions to provide the innovations necessary to link economic and environmental interests. In 2012, the non-profit SIG-NAL was created to meet this need. SIG-NAL broadens the reach of the technical capacity and professional networks of Spatial Informatics Group (SIG) to create a more flexible entity with increased effectiveness in a dynamic economic and political context working for the public benefit.

NEWS:January 2015 New Partnership Announced

New Partnership Allows Remote Alaskan Villages to Mitigate Climate Change and Protect Forests

SOUTH PORTLAND, Maine—Native Alaskan villages will be soon be able to fight climate change while protecting native forests, thanks to a new partnership between the Maine-based the National Indian Carbon Coalition (NICC) and the Alaska Carbon Exchange (ACE).

The partnership will develop verified carbon offsets from Alaska Native Corporation lands using state-of-the-art technology to quantify the carbon stocks on the remote tundra and forests of Alaska. The technical work will be led by the Spatial Informatics Group-Natural Assets Laboratory (SIG-NAL), a non-profit research organization with offices in Maine and California.

The NICC is a non-profit program of the Indian Land Tenure Foundation and the Intertribal Agriculture Council. ACE is a program of the Alaska Village Initiatives, which facilitates economic development in rural Alaska.

Alaska Village Initiatives Executive Director, Charles Parker said the following about the partnership, “Alaska’s rural communities have been feeling the negative effects of climate change for years. With the Alaska Carbon Exchange we are looking to address this issue with a program which protects our traditions and culture, revives our rural economy, and helps protect and renew our land. Our land has sustained us for generations, and with programs like these it can continue to sustain us for generations to come.”

John Gunn, Executive Director for SIG-NAL said that “Measuring and monitoring above-ground carbon stocks can be costly and logistically challenging in remote landscapes. We’re excited to have this opportunity to test new approaches that will help remote villages gain access to global carbon offset markets.”

The Program Director for NICC, Erick Giles, said “We are honored for the opportunity to sustain indigenous communities and protect forest ecosystems. We believe this partnership with ACE will flourish and become a model of innovation that transforms environmental markets in Indian Country.”

The carbon credits will likely be sold in the voluntary carbon market, where organizations purchase the credits to reduce environmental impacts. NativeEnergy, a leading carbon project developer and retailer, believes the carbon credits generated by the ACE program will be very attractive to their credit buyers. “NativeEnergy’s first initiatives were renewable energy projects on tribal land. Our clients want to support Native American tribal efforts to protect their land and culture. The environmental benefits generated give us the mechanism to make the connection,” says Jeff Bernicke, CEO of NativeEnergy.
