21 Reducing emissions and exploring paths to lower-carbon methanol Providing solutions for the emerging low-carbon market supports our strategy of global methanol leadership Efficiency Projects We implemented four projects in 2022 that we anticipate will result in 30,000 tonnes CO2 avoided per year (absolute reductions). Estimated combined CO2 avoided from approved efficiency projects is 100,000 tonnes/year by 2024. ~100,000 tonnes/year (absolute CO₂ avoided) Reduced-intensity Expansion Projects The G3 plant in Geismar, Louisiana, is in the process of starting up and will have one of the lowest emission intensity profiles in the industry. <0.40 tonnes of CO₂/tonne of methanol (estimated G3 intensity) which will lower our average emissions intensity Carbon Capture Feasibility Study Progressing a feasibility study for carbon capture and storage (CCS) at the Geismar site. UP TO $1M for economic feasibility study Renewable Natural Gas Using renewable natural gas or biomass in a conventional methanol process results in a form of green methanol called bio-methanol. Certified by the ISCC to produce bio-methanol in Geismar Green Hydrogen Feasibility Study We are conducting a feasibility study of the potential to gradually convert an existing asset to produce lower carbon intensity methanol using green hydrogen. UP TO $1M for Green Hydrogen feasibility study in 2023 Methanex | The Global Methanol Leader | Investor Presentation October 2023 methanex the power of agility
