ISA and Pacific Gas & Electric Company Announce OneTree Partnership

ATLANTA, Ga. — The International Society of Arboriculture (ISA) is pleased to announce that Pacific Gas and Electric Company (PG&E), one of the largest combined natural gas and electric energy companies in the United States, will provide support through ISA’s OneTree Program as a distinguished partner.

The OneTree Program is ISA’s corporate sponsorship program designed to bring together companies dedicated to improving the community by promoting the professional practice of arboriculture. OneTree partners provide both financial and non-financial support that allows ISA to advance its mission to foster a greater worldwide awareness of the benefits of trees.

“We appreciate PG&E’s commitment to investing in our industry with its OneTree sponsorship,” said Caitlyn Pollihan, the executive director, and CEO of ISA. “With PG&E’s support, ISA can continue to have a global impact by supporting arborists and tree workers who in turn help trees and the community.”

PG&E has a variety of programs dedicated to vegetation management along powerlines across Northern and Central California, in which 25% of its workers are ISA certified arborists, in addition to Certified Professional Foresters.

“To protect public safety, we are taking steps every day to improve the safety and reliability of our gas and electric system.  This includes working with customers and communities to manage trees and other vegetation located near PG&E facilities or powerlines that could cause a wildfire or power outage,” said Chris Hughes, PG&E Vegetation Management Program Manager. “We love trees, and we know our customers in California love trees, and we are happy to be partnering with ISA to help everyone co-exist in the face of our changing climate and increased risk of wildfires,” added Hughes.

Through its OneTree relationships, ISA can provide arborists with programming, services, and research to better equip them to serve and educate the greater public and advance the profession as well as the tree care industry worldwide. Additionally, the OneTree program helps to address critical environmental issues, impact decision and policy makers, spread valuable education and research while also staying on the cutting edge of industry trends, innovation and technology.
