Mining is both an essential human activity, and a surprising contributor to global CO2 emissions, at 4 to 7 percent of global production. Caterpillar is working with Canadian mining firm Nouveau Monde Graphite to create a fully carbon neutral mine using electric vehicle technology.

The three remaining industries are all in profitable sectors and are all engineering related.Access all episodes of This Week in Engineering on engineering.com TV along with all of our other series.
