If you have the means, it is best to switch to a hybrid vehicle. This way you will be able to reduce your petrol consumption, hence, reduce your impact on the environment. 

This is not to say that hybrid cars and electric cars do not have negative impacts on the environment, however, for now the pros seem to outweigh the cons. 

Carpool is an agreement between a group of people to take the same route in the same vehicle. This is a great way to start reducing your greenhouse gas emissions along with your friends and colleagues who work and live nearby. This way, you will be able to share the road journey, connect with people, and reduce your emissions and cost! 

If your city's infrastructure allows it, public transportation is an efficient way to move around from one spot to the next. Taking public transportation has many advantages where you can take that time to read a book, listen to a podcast, or simply talk to the person next to you on the bus! 

Biking and walking remain as excellent options if your destination is nearby. This way, you will be able to exercise as well, breathe in the fresh air, and release some stress and toxic energy. 

I highly recommend choosing this option if your destination allows it!
