Iceland

Iceland is famous for its renewable energy programme that supplies clean electricity and hot water to nearly every resident. They use environment-friendly paper products and cleaning products. All takeaway cups are charged and the proceeds are donated to NGOs. Iceland has clearly labelled recycling and compost containers, with clear photos on top of them showing the kind of items that should go into each container to promote recycling. On 5th June, 2018, which is celebrated globally as World Environment Day, Iceland planted 1,200 trees to offset the carbon emission produced by guests. Interestingly, Icelandic water is pure spring water and you can drink it directly from the tap. Thus, the country has been able to successfully reduce the use of bottled water, the plastic of which has disastrous consequences on our planet. The country is proud of its sustainability efforts and pledges to go completely green soon.

Switzerland

Switzerland is the second greenest country in the world. The country has one of the highest waste‑recycling rates, of more than 50%. It invests heavily in developing future environmental protection techniques, thus ranking first in terms of setting up green technology enterprises. The Swiss need for energy is largely powered by solar and geothermal energy. The concept of car pooling has been adopted by 1 in 60 of the Swiss. This is how Switzerland maintains its lush green meadows and its natural heritage, with active participation from its citizens.
