| Comment | A joint UN-industry effort to look at methane says methane is 86
times more powerful than CO2 as a greenhouse gas, which means
he/they are relying on the 20-year GWP form the IPCC 2013 report.
There is also an effort to get the International Standards
Organization (ISO) to set a standard for methane in lifecycle
assessments that would reflect actual endpoints, such as a global
warming of 1.5 or 2 deg C. That essentially would call for the
20-year GWP as well. The US component to the ISO has recommended
adoption of such a new standard, which would replace the decades
old 21 value.

The California Air Resources Board must seriously consider these
global studies and research.
