There is so much we all could do in our respective areas and sectors. Not only would this improve our carbon footprints, but it also opens up new economic opportunities.
Consider the example of How The Dairy Industry Could be Making Electricity and Reducing Emissions: By turning methane from cow manure into electricity. Not only do farmers seizing this opportunity end up producing more energy than they need (they can sell the access to the grid), they can (potentially) also gain carbon credits from reduced emissions.
What opportunities exist in your sector or area of expertise that you have not tapped into?
