My own opinion is that climate-smart wood means it is tackling climate mitigation, adaptation or both. A quick mnemonic: Sequestration + Resilience = Climate Smart
What does that mean? Well, wood from forestry that stores additional carbon is climate smart. Or wood from a restoration project that is thinning an over-stocked fire-prone forest is climate smart. How much additional carbon is enough? How much more resilient to wildfires should a forest be? These are tough questions to answer objectively.
