Mexico has established a mandatory reporting system for direct and indirect greenhouse gas emissions for all facilities with annual emissions over 25,000 tCO2e. Emitters in the energy, industrial, transport, agricultural, commercial services, and waste sectors will be required to report on various GHG emissions, including carbon dioxide, methane, nitrous oxide, black carbon or soot, fluorinated gases , halogenated ethers, halocarbons, mixtures of these GHGs and any additional GHGs identified by the IPCC and designated by the Secretariat of Environment and Natural Resources (Regulation - Spanish). Every three years, an accredited third party must verify emission reports. The new regulation is a key step forward in implementing the General Law on Climate Change of 2012.
