4 September 2017, The Conversation, This is why we cannot rely on cities alone to tackle climate change. A lot of faith is vested in cities to tackle climate change, and with good reason. A day after the June 1 declaration that the US would exit the Paris Agreement, 82 American “climate mayors” committed to upholding the accord. By August 4, when the US gave formal notice of its withdrawal, there were 372 “climate mayors” representing 67 million Americans. In Australia, too, national intransigence has led to greater expectations of local actions. The Climate Council’s July report declares that deep cuts in cities’ greenhouse gas emissions can achieve 70% of Australia’s Paris goals. The report notes that a majority of Australian cities have adopted climate policies. Many are committed to 100% renewable energy or zero emissions. One of the report’s authors argues that, even without national leadership, Australian cities can “just get on with the job of implementing climate policies”. Many European cities have ambitious emission-reduction targets. Copenhagen plans to be the world’s first carbon-neutral capital by 2025. Stockholm aims to be fossil-fuel-free by 2040. So, at first glance, cities do appear to be leading the way. A word of caution We support local decarbonisation and the desire for cities to be progressive actors. Yet there are ample grounds to be dubious about cities’ ability to deliver on their commitments. Sam Brooks, former director of the District of Columbia’s Energy Division, has laid out sobering evidence on the reality of climate action in US cities. Brooks supports stronger local action rather than “press releases” and “mindless cheerleading”. He shows that most emission cuts in US cities can be attributed to state and federal initiatives such as renewable portfolio standards or national fuel-efficiency rules. Read More here
