  • Direct incentives for smart energy and sustainability projects

    Implementing actions to be more sustainable or to “go green” are shown to be economically beneficial in a number of ways (see my article on the 9 Purely Business Reasons to Go Green). One thing that holds back many companies from these programs, however, is the upfront costs. Although a smart sustainability program will make back that initial investment and more over time, some ...

  • How to better manage refrigerant gases in order to reduce greenhouse gases (GHGs)

    Carbon emissions reporting requires detailed monitoring record keeping of emission sources. Reducing a company's CO2 emissions has an impact on climate change. Carbon reporting needs to be approached in a structured organized way. Doing so in this way is known as carbon management. Carbon (CO2) Emissions Reporting: It's the law. In many countries, carbon emissions are required by law to be ...
