According to World Economics: Sending ‘thank you’ emails may seem harmless, but it contributes to global warming. Each email we send uses electricity and adds a bit of carbon dioxide to the atmosphere. Since there are so many of us sending emails every day, our combined impact is huge. To reduce our carbon footprint, we can stop sending unnecessary emails like ‘thank you’ messages to our boss or colleagues.
In the UK alone, around 64 million unnecessary emails are sent daily. If each person sent just one less email a day, we could cut 16,433 tonnes of CO2 emissions. That’s like canceling 81,152 flights from London to Madrid or 88,270 flights from Delhi to Mumbai.
So, let’s be mindful of our email habits and skip those ‘thank you’ emails. It may seem small, but together, we can make a big difference in fighting climate change and protecting our planet.
So please, let’s all make an effort to stop sending thank you emails and other unnecessary emails as well. It’s essential to stop using unnecessary phones and computers to help reduce our environmental impact.
