Our data has shown that some US companies have clearly made a huge push towards this, with companies across industries from technology and telecom to retail, committed to achieving their net zero target.”

“For those looking to become more environmentally friendly in their own home, assessing your energy usage is a great start. This can be in the form of small changes such as lowering the heat setting on your wash cycle or switching to more energy-efficient lightbulbs.

However, you can also compare energy plans to see if any providers in your area offer a carbon-neutral energy plan so that you can support ongoing investment into renewable energy production.”
