Lowering carbon emissions typically goes hand in hand with increasing efficiency and cost-effectiveness. Calculating and tracking what emissions you are generating will allow you to quickly identify which of your activities use a lot of energy and where potential savings could be made.
Companies are actively looking to do business with other companies that are reducing their emissions. Reducing costs and improving your process will give you a competitive edge in your market.
Brand is everything. Customers and companies care about who they do business with. They want to do business with other companies that have a sustainability plan.
Ultimately, climate change is not going to be solved by one person or an individual company. It will take everyone, including you, to do their part, no matter how small.
