Southeast Asian expert perceptions of solar radiation management techniques and carbon dioxide removal approaches: caution, ambivalence, risk precaution, and research directions

Laurence L Delina IN: Environmental Research Communications

This paper describes the responses of seventeen climate and energy experts from southeast Asia on a purposively designed survey that collected expert opinions on SRM and CDR, their risks, impacts, and governance as they pertain to their countries and region. Respondents showed ambivalence towards these techniques, with many supporting ’natural‘ CDR research and deployment while being cautious about ‚technological‘ SRM and CDR research and deployment.


This Is CDR EP14: The Carbon Removal Leadership Act (CRLA)

by OpenAir

In this special session of „This Is CDR“ the OpenAir Advocacy team unboxes the collective’s newest and most ambitious legislative mission to date. The Carbon Removal Leadership Act (CLRA) is soon to be introduced legislation in New York and other states that, as law, would establish a transparent, standards-based and equitable carbon dioxide removal state procurement obligation.


Carbon dioxide removal’s role to the Paris Agreement’s goals

Meeting the goals of the Paris Agreement and stopping the worst impacts of climate change raises important questions about the role of CDR, how much of it is required and when, and how it can be deployed responsibly. This resource helps answer these questions on CDR, which is also known as Negative Emissions Technologies (NETs), by drawing on IPCC reports, a CDR Primer, and a report from the Institute for Carbon Removal Law and Policy. 


Pereira et al. (2021): From fAIrplay to climate wars: making climate change scenarios more dynamic, creative, and integrative

Mach, Mohale Mashigo, Juan B. Moreno-Cruz, Daniele Visioni, Simon Nicholson, Christopher H. Trisos IN: Ecology and Society 26(4):30;

„We offer a step-by-step guide to the modified Manoa Mash-up method to generate more integrative, creative, and dynamic scenarios; reflect on broader implications of using this method for generating more dynamic scenarios for climate change research and policy; and provide examples of using the scenarios in climate policy communication, including a choose-your-own adventure game called Survive the Century (, which was played by over 15,000 people in the first 2 weeks of launching.“


Nature – Impact of declining renewable energy costs on electrification in low-emission scenarios

„Here we show that further progress in solar- and wind-power technology along with carbon pricing to reach the Paris Climate targets could make electricity cheaper than carbon-based fuels. […] The lower production of bioenergy in our high-electrification scenarios markedly reduces energy-related land and water requirements.“


Webinar: How Can Carbon Mineralization Help Fight Climate Change?

6 December 12:00 PM to 1:30 PM

by Columbia Center on Global Energy Policy

A new report co-authored by Columbia University scholars finds the climate change benefits of enhancing carbon mineralization processes could be enormous. The ICEF Carbon Mineralization Roadmap explores several strategies, including injecting CO2-rich fluids into underground rock formations and exposing crushed rocks to CO2-rich gases. Please join the Center on Global Energy Policy as several co-authors of the report present their recommendations for using carbon mineralization processes.


Cabiyo et al. (2021): Innovative wood use can enable carbon-beneficial forest management in California

Bodie Cabiyo, Jeremy S. Fried, Brandon M. Collins, William Stewart, Jun Wong, Daniel L. Sanchez IN: PNAS December 7, 2021 118 (49);

This study applies a systems approach to assess climate change mitigation potential and wildfire outcomes across forest management scenarios and several wood products. The results suggest a low-cost pathway to reduce carbon emissions and support climate adaptation in temperate forests.
