I’ve been working on voluntary clean energy procurement for 25 years, and it’s always been clear to me that large energy buyers need to focus their efforts on energy procurement that decarbonizes the whole grid, not just their own buildings. Today’s definitions of the location-based method (LBM) and MBM are clear and have underpinned clean energy markets for over a decade. For a decade, large energy users have been able to aggregate their facilities’ energy use over large geographies on an annual timescale to provide large, credit-worthy contracts to clean energy project developers, resulting in 200 gigawatts of new clean energy capacity added to global grids. If anything, a tighter alignment is expected to decelerate clean energy transition. A simple verb change stating that hourly matching should follow an optional ‘may’ rather than a required ‘shall’ approach will send a strong message.
