Cop27 showed why a new economic order is vital

For three decades, world leaders at international conferences have pledged to cut greenhouse gas emissions and greener energy sources have been developed, yet emissions have continued to rise (Big story, 25 November).

Even as previously extreme weather events become normal and millions of people are displaced by such events, there is still no sign of electorates in richer countries being willing to vote for rationing or much higher prices for car use, air travel and other particularly damaging activities.

Clearly, we urgently need a new strategy. The world’s biggest economies or the UN need to invest in removing carbon dioxide from the atmosphere, reducing warming, and purchasing and protecting land such as rainforest. Richard Mountford Hildenborough, England, UK

Damian Carrington’s analysis left me with the impression that the fossil fuel industry’s greed had triumphed over science and common sense.

Australia’s delegation came away with little to show, except being part of the loss and damages fund. Back home, the Labor government is still effectively being blackmailed by the fossil fuel industry into condoning, if not supporting, its demands to continue rampant emissions.

Australia is blessed with abundant sunshine and wind, the space to build solar and wind farms, and the knowledge to develop and multiply them. When will the fossil fuel lovers ever learn?
