While urbanization creates some of the greatest impacts in climate change, urbanization can not be avoided due to the growing population and increasing demands in the economy.

A few years ago, I did a library research paper on climate change and air pollution in the Philippines and found out that one of the greatest contributors of greenhouse gas is the burning of fossil fuels (petroleum, coal, etc.).

Here are some of the answers of the government to increasing GHG emissions and their flaws:

1. Promoting the use of public transportation to reduce vehicles on the road
- While it would indeed succeed in reducing the number of vehicles on the road, poorly maintained vehicles (PUJs, buses, etc) burn more fuel and produce more emissions, therefore only reducing air pollution by a small portion.

2. The promotion and use of electric vehicles (E-jeepneys)
- Most people agree that electric vehicles are indeed a solution to the increasing air pollution since they emit no byproducts. Electric cars indeed do not have emissions, however, it still contributes to GHG emissions indirectly through electricity since major electric companies in the Philippines produce electricity through fossil fuels.

3. Importation of hybrid vehicles
- Although the importation of the said vehicles was made by car companies to help reduce air pollution, these cars did not catch on simply because the cars were more expensive due to additional taxes (caused by importation of the car) and the government did not give any incentive for future car owners to purchase hybrid vehicles.
***As of now, there is currently a bill pending for approval to boost demand on hybrid vehicles

In my opinion, although investing in renewable energy sources may need a higher capital compared to non-renewable energy sources, renewable energy would be able to provide better in the long run.
