Jacinda Ardern, prime minister of New Zealand, declared a climate emergency for the government and the public sector to achieve carbon-neutral by 2025. She said the 2025 goal will be set as the standard for the country to reach zero emissions of greenhouse gases by 2050. This is a commendable mission that can set as an exemplar for the rest of the world.
Due to my limited imagination, I do not know what I can do to reduce carbon emissions in my daily life other than driving less often and taking train and bus more often. Governments in all around the world offer some rebates for electric cars and hybrid electric vehicle. I can consider about this option when I need to buy a new car.
I have some doubts about zero emissions though.
Firstly, you need to charge your electric car. And we need petroleum, natural gas and coal to produce electricity. If I were to always charge my car at home and outside carparks, some fuel would need to be burned and carbon to be emitted for the production of the electricity that supports my car to continue moving and functioning. Does this mean I actually fail to achieve a zero emissions?
Secondly, speaking of the most direct zero-carbon target, do we count on solar energy, wind and hydro power which are natural and zero-carbon? When will the options of clean energy fully replace the energy capacity provided by petroleum?
Science is the only way to find out the answers to my questions. Documentaries are good for learning, for I heard that Scandinavian countries are doing well in cutting emissions and clean energy. Some good podcasts are also good, if I don’t have enough time to watch documentaries.
