Cop27 live - latest news updates

Mexico, one of the world's biggest greenhouse gas emitters, is expected to announce a hotchpot of old, inadequate and undeliverable climate pledges that will leave its Paris pledges in tatters, experts have warned.

Climate action has nosedived under the leadership of Andres Manuel Lopez Obrador, who had to be blocked from rolling back Mexico's modest Paris greenhouse gas targets by the country's supreme court, and emissions are rising.

A reduction in methane emissions from the state-owned oil company, Pemex - an important but existing target for which Pemex has been fined for non-compliance.

A 1,000MW state-opened solar plant - construction is already under way for a 180MW project, and the government had previously already ruled out further investment to expand the energy potential.

A lithium commitment. Mexico has the ninth-largest identified deposits of lithium - a crucial mineral for electric vehicles and other green technologies - but there has been no government investment so far in advancing extraction, and none is currently being mined. Experts say the country is years away from producing its first gram of lithium.
