Those looking to explain their efforts toward sustainability within the framework of climate change should check out the report released April 12 from the United Nation’s Intergovernmental Panel on Climate Change. The report is the result of four years of intense scientific collaboration by hundreds of authors from around the world. You can either read the entire report, pieces of it, or the Summary for Policymakers. I read through the 33-page Summary for Policymakers (it refers to specific sections of the complete report) and it includes plenty of information to justify your own company or property’s efforts to reduce greenhouse gas (GHG) emissions. According to the Summary, despite a growing number of climate change mitigation policies, annual GHG emissions grew on average by 2.2 percent per year from 2000 to 2010 compared to 1.3 percent from 1970 to 2000.
