Platts discontinues Household Devices LDC project differential, Oct. 1
Platts, part of S&P Global Energy, has discontinued its Least Developed Countries Project Differential for Household Devices carbon credits, effective Oct. 1, 2026.
This reflects changing dynamics in the household devices segment of the voluntary carbon market, including how premium segments of the cookstove credit market are categorized.
Platts initially proposed this discontinuation via a subscriber note published June 5.
