Recent updates from the Science-Based Targets initiative (SBTi) have pushed an old debate into public awareness, highlighting a perceived divide between emissions reductions and carbon removals. While SBTi's new guidelines focus on cutting emissions directly within company operations, some argue this creates a false dichotomy, downplaying the essential role of carbon removals in achieving net-zero goals. In reality, both strategies—reductions and removals—are not opposing forces but complementary tools needed to combat climate change effectively.

In Episode 69 of Bionic Planet, I spoke with Eli Mitchell-Larsen, a self-described "carbon removal evangelist," who provides valuable insights into the various types of carbon removal methods, including nature-based, hybrid, and engineered solutions. I'm rerunning this episode here today as episode 111.

The discussion begins with a focus on the importance of both reducing emissions now and removing existing gases from the atmosphere to achieve net zero emissions by 2050. The host and guest emphasize the need for a comprehensive approach that includes a mix of nature-based solutions, such as afforestation and soil carbon sequestration, as well as engineered technologies like direct air capture.

Throughout the episode, the host and guest explore the different categories of carbon removal, including biomass carbon removal and storage, geological storage, and unconventional methods like kelp farming. They highlight the importance of understanding the capture, utilization, and storage of carbon in evaluating the effectiveness and durability of each method.

The conversation also touches on the evolving landscape of carbon removal technologies, with a focus on the need for continued research and development, government support, and deployment incentives to scale up promising solutions. The host and guest stress the urgency of accelerating the deployment of carbon removal strategies to address the escalating climate crisis.

Overall, the episode provides a comprehensive overview of the complexities and challenges of carbon removal and reduction efforts, emphasizing the need for a multifaceted approach to combatting climate change effectively. Through engaging dialogue and expert insights, listeners gain a deeper understanding of the critical role of nature-based and engineered solutions in achieving a sustainable future.
