WELLINGTON, Aug. 22 (Xinhua) -- New regulations for New Zealand's fuel specifications will support the growth of lower-emission fuels that are better for people, the environment and cars, Energy and Resources Minister Judith Collins said on Tuesday.
The Regulations set out minimum standards for fuel performance, and change incrementally over time to keep up with new technology and international best practice, Collins said in a statement.
There are four significant changes -- three that enable greater fuel supply choice and market-led innovation in the fuel mix; and one to reduce harmful emissions.
The changes includes introducing a total oxygen limit, which potentially allows a wider range of fuel blends, increasing New Zealand's limit for methanol in petrol from 1 to 3 percent volume, raising the biodiesel blend limit in diesel from 5 to 7 percent, and reducing the sulphur level allowed in petrol from 50 to 10 parts per million.
Reducing the sulphur level in petrol is specifically targeted to reduce harmful emissions, which will have health and environmental benefits, the minister said, adding that this is consistent with the most stringent fuel standards in the world, most notably in Europe, Japan and the United States.
The changes will take effect from Oct. 2, apart from the change to the maximum sulphur level, which will come into effect on July 1, 2018.
