Kiwi stations pumping greener fuel

You can still be a green driver without a fancy electric car, reckons oil company Gull. The Kiwi-owned business is squawking about having sold 24 million litres of bio-fuel, a feat which has reduced the greenhouse gas emissions of its customers by 57,000 tonnes of CO₂.

Gull mixes ethanol made from non-food dairy by-products into two of its high-performance petrol mixes, and mixes bio-diesel made from used cooking oil into its diesel blend. Bio-fuels benefit the environment because they release greenhouse gases that were already in the planet’s carbon cycle, rather than adding new CO₂ from fossil sources.
