Energy efficiency is the most effective company-wide first steps CEOs can take to launch a climate change program, according to a team of environmental scientists and climate researchers. The panel, which includes 54 fellows of the Switzer Foundation, an environmental non-profit, participated in a survey titled, “What the Scientists Know: How Business Leadership can Help Solve Climate Change“. To best leverage a CEOs leadership, the scientists top rankings included: improving energy efficiency of existing operations, converting to clean and renewable energy, engaging in climate change policy discussions, consideration of climate risk in asset management and buying carbon offsets. Carbon offsets wasn’t listed as a top priority for companies. The panel also pegged the purchase of renewable energy credits as the last corporate priority; the most popular write-in suggestion for top priority was reducing energy consumption.
