Joining SMAC
The Subnational Methane Action Coalition (SMAC) is a group of governments committed to reducing methane emissions. The Coalition includes partnerships with university research centers, nonprofit organizations, and wider government networks. There is no cost associated with joining.
SMAC puts each member in firm control of their methane strategy. Governments commit to addressing methane, according to their own needs, in the sectors that they believe present the greatest opportunities. While members are not required to set binding emissions targets, the coalition is designed to encourage ambitious efforts.
Member Benefits
SMAC members gain access to an unparalleled network of methane experts, including:
Inventory support from data analysts with Climate TRACE
Policy guidance, tailored to each jurisdiction, from methane policy researchers at UC Berkeley
Technical assistance from the State of California’s Methane Research Program
Remote sensing insights from the Carbon Mapper satellite program
Sector-specific support for oil and gas (incl. RMI), landfills (incl. GAIA), coal (incl. Ember), and livestock (incl. UC Davis, California Department of Food and Agriculture)

Steps to initiate an alert (~5 minutes)
You can set up email alerts for new plumes in your jurisdiction. The simple 3-step process is as follows:
Visit the Carbon Mapper data portal, click the person icon on the mid-left of your screen, and create an account (takes ~1 minute). In the future, you can sign in using these credentials to view and adjust saved searches.
Use filters to select your search criteria and area of interest. Make sure to select the area name under "Filter by Area of Interest" and NOT "Zoom to Location." You can then adjust the dates of plume detection, both CO2 and CH4, sector of emission, and so on.
Click the “Save Search” button, and choose an alert frequency that meets your needs.Start receiving emails summarizing new data on a daily, weekly or monthly basis!

In this joint technical seminar and SMAC community of practice, Professor Ermias Kebreab from UC Davis and Methane Research Fellow Shivani Shukla from UC Berkeley bring insights on methane reduction strategies in the livestock sector, followed by a SMAC peer case study presentation by Minas Gerais, Brazil on policies such as the ABC+ plan and PLAC, and other state programs and solutions on livestock methane.
Speakers: Professor Ermias Kebreab, UC Davis; Gustavo Gomes Pereira do Nascimento, Veterinarian and Technical Advisor – Directorate of Productive Chains, Minas Gerais, Brazil; Shivani Shukla, Methane Research Fellow, UC Berkeley CLEE.
-
Researchers from UCLA, Stanford, and Berkeley Law discuss how public officials are using satellites to tackle methane.
Speakers: Juan Pablo Escudero, Cara Horowitz, Fran Reuland, Ted Lamm, Shivani Shukla, Gil Damon

Carbon Mapper is a nonprofit organization that uses advanced remote sensing technologies to detect, pinpoint, and quantify methane and CO₂ super-emitters at the facility level. By providing transparent, actionable data, they empower operators, regulators, and civil society to take targeted action—supporting everything from leak detection and policy development to global efforts like the Global Methane Pledge. Kenzie and Jordan will walk you through the many ways you can leverage Carbon Mapper’s satellite data to accelerate emissions reductions, including through their free and open data portal.
Speakers: Kenzie Huffman, Director for Strategy and Partnerships, Carbon Mapper; Jordan Giaconia, Deputy Director for Impact, Carbon Mapper.

Colorado is a national leader in methane policy through innovative monitoring and regulatory strategies. In this session, Stefanie Shoup and Tim Taylor from the Colorado Department of Public Health and Environment share how the state is using ground-based, aerial, and satellite technologies to track methane emissions. They also discuss Colorado’s efforts to regulate emissions from the oil, gas, and waste sectors, with a focus on strengthening landfill requirements and advancing subnational leadership.
Speakers: Stefanie Shoup, Manager, Colorado Office of Innovations in Planning and Air Quality Data; Tim Taylor, Head of Strategy Development, Colorado Air Pollution Control Division
-
With the launch of multiple methane detection satellites, the amount of data and information methane emissions is expanding substantially. How can jurisdictions receive and use this data?
The California Air Resources Board (CARB) is a world leader in methane observation. Dr. Jason Schroeder and Dan Phillips will share lessons from CARB’s methane detection work, use of satellite data, and interactions with facility operators. They will also introduce California's new methane plume alert system.
Speakers: Dr. Jason Schroeder, Manager of Integrated Measurements of Air Pollution Section for the California Air Resources Board; Mr. Dan Phillips, Air Pollution Specialist, California Air Resources Board
-
Climate TRACE is a nonprofit coalition building a timely, open, and accessible inventory of exactly where greenhouse gas emissions are coming from. This session will provide an introduction to Climate TRACE and its data products; its applications; and a demonstration of how it can be used for methane tracking and mitigation.
Speakers: Lekha Sridhar, Research and Special Projects Lead for WattTime
Methane Strategies

Agriculture
Methane from the agricultural sector comes mainly from livestock and rice cultivation. Agricultural methane solutions often make food production more efficient and profitable.
Fossil Fuels
In the oil, gas, and coal sectors, methane can be released by the extraction and distribution of fuel. Methane that is retained or captured can be used to generate heat and electricity.
Waste
Landfills and wastewater produce methane through the decomposition of organics. This can be remedied through composting, fuel capture, and engineering improvements.
