Last year California held its first auction of carbon credits under the state's greenhouse gas reduction law.

去年，根据该州减少温室气体法，加州进行了首次碳信用额拍卖。

The proposed decision was announced after the House of Representatives passed a bill that would put into law a reduction in Australia's greenhouse gas emissions by 43 percent below 2005 levels by the year 2030.

这项拟议的决定是在澳大利亚众议院通过一项法案后宣布的，该法案决定，到2030年，澳大利亚的温室气体排放量在2005年的水平之上减少43%。
