SB5467 was an identical companion bill in the Senate; it’s now dead – in the Senate X file.

Summary –

Mass timber panels (which are also called cross-laminated timber) can replace a most of the steel and concrete in large buildings, avoiding the emissions from producing those and sequestering the carbon from the trees for years.

The bill extends the current lower business and occupation tax rate for timber and wood products to apply to mass timber. (It’s 0.2904 percent rather than 0.484 percent until 2024)
