Congratulations to MCE for earning the Sustainable Economics Award from Sustainable Contra Costa this year. Thanks to its customers and community partners, MCE is years ahead of the timeline for achieving renewable energy and transportation electrification goals of the GCAS Read more about MCE's leadership and ambitious goals HERE Also learn about MCE's EV rebate program HERE

Has your city upgraded its public facilities to 100% renewable? For those cities who have adopted MCE and their energy provider, you have the power to change the amount of renewable energy that is put on the grid. When a city chooses “deep green”, then all off the power you buy for your city buildings comes from 100% non-polluting, Green-e Energy certified, wind and solar power produced in California. Opt-Up to Deep Green HERE


Special Report on Global Warming of 1.5C, SR15 was published by the Intergovernmental Panel on Climate Change (IPCC) on October 8th. The report contains over 6,000 scientific references and was prepared by 91 authors from 40 countries. Its key scientific input will be included in the Climate Change Conference in Poland in December, when governments review the Paris Agreement to tackle climate change.  Read the report HERE

City News

New York City installs alarming climate change traffic signs at Mayor’s behest. “Climate Denial Kills,” “Abolish Coal-Onialism,” “50,000,000 Climate Refugees” and “End Climate Injustice” are just some of the warnings passersby will see as part of the effort to sound the alarm on global warming. De Blasio’s office teamed up with the Climate Museum , “When you see a traffic sign, your pulse quickens a little and you know you have to be on the alert for a changing condition that could affect your safety,”  Read more HERE

Cities play a Central Role in Climate Change. The IPCC SR15 report points out that it is theoretically possible to limit the increase in global temperatures. ““By creating an enabling city-level policy and finance environment, we can facilitate this... We also believe that city priorities and low carbon progress should not be mutually exclusive. If we focus on low carbon goals, it can help with a wide range of issues such as housing, transport, jobs, skills and health... mayors and their teams have the opportunity take a step back and view their city and its challenges as a whole..”  Read more HERE  

Cities have 15 months left to slow climate change, says IPCC report. previous efforts to limit warming to 2 degrees Celsius above pre-industrial levels will not be enough to mitigate serious impacts. The report calls for nothing less than a complete overhaul of the world economy. Emissions worldwide will need to peak by 2020, meaning dramatic action needs to be taken within 15 short months. In 27 cities, including nine in the U.S., emissions have already peaked. Read more HERE

Mayors Are Rallying Around the Mississippi River from Minnesota to Louisiana, the Mississippi is the source of increasing problem flooding, but it’s also the key to a clean water supply and a healthy economy. Two years ago cities experienced a 1,000-year rain event that caused catastrophic floods in southern Louisiana. Since then Mayor Lionel Johnson and others are hearing from his constituents about the need for adaptation and resilience planning for a changing climate. Read more HERE

Mayors join more than 200 organizations, scientists, and elected officials in releasing the #Stand4Forests platform demanding the protection of U.S. forests as a vital climate solution. "Climate science shows that we cannot stop a climate catastrophe without scaling up the protection of forests around the world. Signatories include mayors from across the country, organizations such as the Natural Resources Defense Council and Sierra Club, and leading climate scientists and advocates. Let’s go Contra Costa leaders; join the list of signatories HERE

Last month, mayors, governors, local leaders and businesses stepped up to fill the gap left by this administration’s inaction. Over 3,500 leaders from states, cities, and businesses, representing 157 million people and $9.46 trillion in GDP,  have ramped up their efforts to cut carbon pollution as the rest of the world continues to work toward the goals of the Paris Agreement. Read more HERE


Air pollution: Climate action can prevent 1 million premature deaths annually. The Global Covenant of Mayors for Climate & Energy and the New Climate Institute shows that climate action, which includes energy efficiency retrofits in buildings, enhanced bus networks and renewable energy initiatives, could generate 13.7 million jobs in cities and save 40 billion hours of commuters’ time plus billions of dollars in reduced household expenses each year.

The earth is on a trajectory to warm 3-4°C by 2100. This heat map details how that rise in temperatures will affect major metropolitan hubs. The reality is that the earth is currently on a trajectory toward a 3-4°C temperature increase by 2100.  Specific climate modeling projections, and how they will affect residents in various global cities, depend on location. To help conceptualize this variation in temperature increases.

Google, in partnership with the Global Covenant of Mayors for Climate and Energy, launched the Environmental Insights Explorer tool to give cities easy access to climate-relevant data. The tool uses Google Maps and other Google services to calculate transportation emissions, building emissions and rooftop solar potential in a standardized format. Read more HERE
