Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

” The MIT report said that natural gas should be seen as a “ bridge ” to a low-carbon regime, rather than as the ultimate long-term solution itself. MIT: The Future of Natural Gas. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas.
