Touted as the UK’s first eco-friendly car insurance, Ecoinsurance offers customers a cleaner conscience and a greener planet, at no extra cost. Each vehicle insurance policy comes with carbon offsets for 20% of the customer’s car’s CO2 emissions, based on an average passenger car with average annual mileage. Customers who drive cars that emit less than 100 grams of CO2 emissions per kilometer receive an extra 10% discount on their policy. (This includes the Honda Insight and Smart Diesel, but not the more popular Toyota Prius.)
