The General Law on Climate Change has established several national measures to mitigate the effects of climate change. Mexico’s main goal
is to reduce greenhouse gases emissions by implementing Carbon, Capture, Use and Storage (CCUS) technologies.

CCUS Objectives:✓Reduce CO2 emissions✓CO2 storage in mature oil reservoirs✓Increase the recovery factor of mature oil reservoirs✓Get more oil reserves✓Use of CO2 as an EOR process in Mexico✓Mutual collaboration with other areas in Mexico

Mexico is committed to reducing 50% of greenhouse gas emissions by 2050, which 19% ofmust come from Carbon Capture and Sequestration (CCS) technologies.

50%

Mexico has boosted the use of public transportation to reduce the use of particularvehicles. Moreover, since 2015, the increasing use of hybrid electric vehicles inmetropolises has promoted GHC reduction.

Pemex is strongly committed to reducing GHG emissions. Therefore, it will continue thefollowing activities: analysis of carbon markets (short, medium and long term), analysis ofpotential fields to apply CO2 as an EOR method and documentation of CCUS strategy.
