WELLINGTON, New Zealand (AP) — New Zealand lawmakers have joined forces across the aisle to pass a bill aimed at combating climate change.

The Zero Carbon bill aims to make New Zealand reduce its greenhouse gas emissions to the point the country becomes mostly carbon neutral by 2050. It gives some leeway to farmers, who bring in much of the country's foreign income.

The bill was spearheaded by the liberal government but in the end was supported by the main conservative opposition party, which nevertheless promised changes if it wins the next election.

The bill would require all greenhouse gases except methane from animals to be reduced to net zero by 2050. Methane emissions would be reduced by 10% by 2030 and by between about one-quarter and one-half by 2050.
