On October 29, 2018, Emmett Institute faculty submitted a comment letter in support of California Air Resources Board’s proposed Tropical Forest Standard. The authors conclude that approving the standard presents an opportunity for CARB to lead the world in tropical forest protection and conservation. Tropical forest protection is an indispensable strategy for fighting climate change, protecting public health, preserving biodiversity, and protecting and enhancing the livelihoods of forest-dependent peoples. With this standard, California can establish a high-quality global model for assessing international forest offsets and signal to jurisdictions across the world that protecting forests is critically important.
