The WA Government has rejected guidelines from its own EPA requiring major LNG projects to be carbon neutral.

The WA Environment Protection Authority (EPA) called for new and expanding LNG projects to buy carbon credits to offset their emissions.

But Labor premier Mark McGowan is refusing to endorse the guidelines, following intense lobbying by the oil and gas industry.

The EPA withdrew the revised guidelines pending further consultation with industry, allegedly after a phone call from the Premier.

Recent federal government emissions reports showed the northern WA LNG industry was the main driver of an 0.9 per cent increase in national emissions in the year to September.

WA’s refusal to act means there is now no state or federal policy to address the nation’s largest source of growth in heat-trapping emissions.
