The most recent Greenhouse Gas Inventory (2012) for our region has recently been released, showing a slight decrease since its peak in 2010. Nationally, this same trend is attributed to reduced emissions from electricity generation, improvements in energy efficiencies, reduction in travel and yearly fluctuation in prevailing weather conditions. For the Tucson region the two largest sources of GHG emissions are Electricity (63%) and Gasoline (22%).
Meanwhile, the latest AR5 Intergovernmental Panel on Climate Change report is endorsing a “carbon budget” or limit to how much carbon can be put into the atmosphere. Given current rates of fossil fuel burning, we will burn through that budget by 2040. And even if we do transition to a zero-carbon culture by that time we will only have a 50/50 chance of stabilizing a 2 degree C rise in temperatures.
To date the planet is experiencing less than a 1 degree rise, producing changes outside “normal” including increasing temperatures, decreasing water supply, increasing health and social problems, increasing intensity of wildfires and flooding, and greater demands on our infrastructure including electricity production and mobility. If we put 2 and 2 together, the climate change picture is definitely not pretty – the challenge huge and “solution” – imperative.
Minneapolis just reached a milestone agreement to partner with their electricity utility to reach their goals to reduce carbon emissions 80% by 2050.
Could Tucson do the same? What would it take? Where will leadership come from?
