The Softwood Lumber Board (SLB), in partnership with the USDA Forest Service (Forest Service), is expanding its Accelerator Cities Program to advance affordable, sustainable building solutions through wood construction. Building on successful collaborations in Boston, Georgia, and New York City, the next phase of the initiative introduces new city-led programs in Portland, Oregon, and Santa Monica, California. Launched to help cities pilot and scale low-carbon building approaches, the Accelerator Cities Program provides funding, technical support, and peer learning to drive innovation in wood design and construction. Each city’s program focuses on improving housing access, reducing embodied carbon, and strengthening local economies through wood-based development. “Each city we partner with brings new insights into how mass timber can help meet housing, sustainability, and economic goals,” said Cees de Jager, President and CEO of the Softwood Lumber Board.
