China, Russia and Canada’s current climate policies would drive the world above a catastrophic 5C of warming by the end of the century, according to a study that ranks the climate goals of different countries. Fossil fuel lobbies in these countries are so powerful that government climate pledges are very weak, setting the world on course for more than 5C of heating by the end of the century.
Only slightly better are the group of countries that are pushing the planet beyond 4C. Among them are the US, which has huge emissions from energy, industry and agriculture somewhat offset by promises of modest cuts and more renewables. Australia, which remains heavily dependent on coal exports, is also in this category.
While even the EU, which is usually seen as a climate leader, is on course to more than double the 1.5C that scientists say is a moderately safe level of heating. Authors of the paper say their actions lag behind their promises to set a positive example
They also note that a few key sectors are currently omitted, including land-use change (which is fundamental in rapidly deforesting nations such as Brazil, Argentina and Indonesia), international shipping and aviation.
