Establishing Biogas-Powered Cold Storage in Rural India for Methane Mitigation and Sustainable Food Systems (2023)

Mitigating post-harvest food loss can result in economic benefits for farmers, increase food security, and reduce methane emissions from organic waste. An estimated 30 percent of food produced in India is lost or wasted, despite the country ranking 94th out of 100 on the 2020 Global Hunger Index (Bagai, 2020). Almost half of post-harvest food losses in India are attributed to the lack of a reliable cold chain, the integrated network of refrigerated storage facilities, transportation, and merchandising technologies that maintain food quality moving from harvest to the consumer (Peters et al., 2019). Cold-chain technologies are energy intensive and typically powered by fossil fuels. In recent years, there has been a focus on clean energy powered cold-chain solutions, including renewable energy powered cold storage facilities that store commodities immediately after harvest.

Methane Observations for Large Emission Event Detection and Monitoring

7–9 January 2025, Virtual

This event will be conducted in Spanish.

While carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities, methane is estimated around 80 times more effective at trapping heat in the atmosphere on a 20-year timescale. Methane is an attractive target for mitigation activities because it has a relatively short decadal-scale lifetime in the atmosphere (as compared with the century-scale carbon dioxide lifetime), it can be utilized as an energy source or combusted (converted to CO2) in order to reduce its global warming potential, and the safety issues associated with high concentrations of this flammable gas. Many activities can lead to the release of large concentrations of methane during the course of normal industrial operations or as accidental releases, these are often referred to as super emitter events, which can be identified from modern satellites. 

This introductory two-part training will begin with an introduction to the U.S. Greenhouse Gas Center and provide participants with an overview of how methane observations from the Earth surface Mineral dust Source Investigation (EMIT) mission can be used to identify and monitor areas of high methane enhancement. This course will also demonstrate how to navigate the U.S. Greenhouse Gas center portal to access data products as well as highlight tools for visualizing methane observations.

By the end of this training attendees will be able to:
  1. Identify the goals and objectives of the U.S. Greenhouse Gas Center
  2. Define the roles of methane and large emission events in climate change
  3. Identify the sensors used to measure methane
  4. Recognize the strengths and limitations of satellite observations used to measure methane for large emission event tracking
  5. Navigate the U.S. Greenhouse Gas Center Portal and the EMIT Open Data Portal to access and visualize data for large emission event tracking
Audience
Federal, state, and local government agency representatives, United Nations agencies with policy mandates related to GHG emission measurement, monitoring and mitigation (e.g., UNEP), entities whose operations produce methane (i.e. oil and gas sector, landfills, livestock, etc.), as well as non-public sector entities with roles/responsibilities in providing GHG data, solutions and services.

University students, early career researchers, and the media may also be interested.

Course Format
Two, 90-minute parts on 7 January and 9 January 2025
Each part includes a 30-min Q&A session
