It is wonderful that several Catholic organizations are cutting back on their consumption of fossil fuels without even being prompted. Other organizations should follow suit: climate change harms everyone, and fossil fuels are a big part of that concern. Therefore, while government mandates are wonderful, more people and companies should do their part (on their own) to cut back.
I do think that organizations should work to reduce their fossil fuel consumption regardless of government mandates. Protecting our environment and doing what we can to reduce energy consumption and pollution is important for us all. Catholic organizations cutting back on their fossil fuel consumption set a positive example for other organizations to follow.
It is very commendable for Catholic organizations to do this without being forced to. This demonstrates that they are willing to do their part in making the world a little better. Hopefully other companies will follow their example. Having said that, I understand that most companies and organizations are not in the financial position to do that, and without government mandates, they could be at a disadvantage if they cut down on fossil fuel consumption while other companies do not. It is undoubtedly the right thing to do, but it's not necessarily practical for many companies and organizations.
Fossil fuels are very harmful to the environment, and our continued use of them will harm our earth even more. We have already caused a considerable amount of damage to our atmosphere, but the sooner we can eliminate our carbon footprint the better it will be for our children and future generations.
