While a number of excellent campus climate planning resources are available, this guide attempts to fill a gap by providing an abundance of "how-to" information. The goal of the guide is to assist climate action planning teams at schools that are well versed in campus climate issues and well along in the CAP (Climate Action Planning) process as well as those that are just beginning in this endeavor and may be wondering "where" to start and "what" to do. Planning steps are presented in a logical sequence, but you may find that proceeding in a different order makes more sense for your school or that working on a number of these items simultaneously will be most effective. You can also use this guide as a reference book and just consult topics of interest. All of the topics covered in this guide would make more sense if amply illustrated by real-life examples of campus projects and initiatives. However, to keep the guide's length manageable, campus examples are generally provided via reference to appropriate webpages on the AASHE (Association for the Advancement of Sustainability in Higher Education) and ACUPCC (American College & University Presidents' Climate Commitment) websites. In the event that campus examples for particular topics are not available on these sites (or if there are other websites with good campus examples), those other links are also provided. Section 12 of this guide, "Campus Climate Action Planning Resources," lists and provides links for a number of other helpful CAP resources--organizations, publications, and web-based information. A list of resources is included. [Funding for this paper was provided by the American College & University President's Climate Commitment.]
