This will be the second of three workshops as part of the CO2-Urban Synthesis and Analysis (CO2-USA) project bringing together leading scientists, practitioners, and policy makers who are working on understanding urban greenhouse gas emissions.  The project aims to synthesize researchers’ findings and to bring together leading scientists and policy makers in order to better understand urban GHG emissions. This workshop will highlight new scientific findings, progress towards analysis of urban GHG emissions, and will facilitate interaction between scientists and policymakers.

getting around salt lake city

Salt Lake is laid out on a simple grid system. If you think of it in terms of longitude and latitude, the zero-point in Salt Lake City is Temple Square. Virtually every address in the city has a set of two coordinates telling how far east or west and how far north or south it is from Temple Square (or the corner of Main and South Temple Streets to be exact). Although an address such as 682 East 400 South may look strange to you, just remember that it simply describes a location on the grid. Consequently, both “halves” of the address (“682 East” and “400 South”) are equally significant, the second half being the street name and the first half being a specific point on that street. Even streets with names (Harvard Avenue, for instance) also have a numbered “coordinate.” If you were looking for Harvard Avenue, it would be helpful for you to know that its coordinate is 1175 south. Read more here.
