Subject: CARB NWL must include a net GHG removal scenario
Comment:
What are we missing? A sufficiently aggressive, but necessary target. The current projection that California NWL will produce up to 400 MMT of net emissions (no net removal) by 2100 should result in a coordinated campaign of planning, implementation and evaluation to accelerate NWL sequestration. At least one of the scenarios to be considered should achieve net removal of emissions from Natural and Working Lands (NWL) by 2050. This will not be achieved by business-as-usual; however, the scale of the climate crisis and a cost-effective approach to meeting California's climate goals requires that CARB, CDFA, and CNRA model such a scenario. As documented again in the August 2, 2021 CARB workshop on Engineered Carbon Removal, carbon sequestration from Natural and Working Lands is substantially more cost-effective than sequestration using Engineered Carbon Removal or Direct Air Capture methods. In addition, Natural and Working Lands sequestration has the potential to be near term feasible and scalable. What are the biggest threats to NWL that must be included in modeling? While the importance of stakeholder involvement in the process was emphasized at the workshop, it is ultimately CARB's responsibility to assure the appropriate use of policy level levers and incentives to achieve California's climate goals. Not all stakeholders will necessarily be in agreement--they should not hold veto power over such a critical objective. Reaching an aggressive target for NWL sequestration will require refining the strategies and GHG consequences, investing targeted resources, and improving our models--using greater geographic detail and independent verification to assure that long-term sequestration is accomplished.
