With getting any sort of action on climate action in Oz such a tough challenge, you'd be forgiven for thinking that no other countries were helping show the way.
Last week however the UK conservative-lead coalition government announced they will be making a 50% cut in carbon emissions by 2025. This won't just be an aspiration either, it will be the law of the land. i.e.: legally binding.
This is the most ambitious carbon pollution reduction target of any developed country and comes at a time when the UK economy has been struggling. So why are they doing it?
Well for one thing they are acting in line with what the science says developed countries need to do to limit dangerous levels of global warming.
Also of great importance, they believe moving to a low carbon economy will create innovation, investment and jobs and so be an overall benefit to the economy.
And thirdly, as it stands the UK is highly dependant on imported fossil fuels and their north sea oil supplies are decreasing. Moving to a low carbon economy will make the UK more energy independent and so less venerable to swings in the oil price and less dependent on Russian natural gas etc.
So with the UK moving towards such major cuts, it makes you realize that the cuts proposed in Australia of 5-15% by 2020, aren't that large by international standards.
