Greening the PH airline industry

WHEN policymakers and the public think of the environmental impact of transportation, specifically harmful emissions, attention is naturally focused on the road transport sector. This is reasonable because road transport is the biggest part of the transportation ecosystem, and is responsible for a very large proportion of the country's environment-killing emissions. However, there is another part of the transportation sector, one that is critical to the Philippines, that has a significant enough contribution to greenhouse gas (GHG) emissions that some countries have begun to impose restrictions on it: the air transportation sector.
