The Harper government faced a grilling from global climate officials Thursday, as countries’ representatives questioned Canada’s policies and commitment to reduce greenhouse gas emissions.

Canada’s chief negotiator Louise Metivier presented Ottawa’s plan at a UN climate conference in Bonn, Germany, where governments are aiming to make progress towards an international agreement to be concluded in Paris in December.
Ms. Metivier said Canada has made an “ambitious” commitment to reduce greenhouse gas (GHG) emissions by 30 per cent from 2005 levels by 2030, and is working with the provinces to meet that goal. It has also committed to a 17 per cent reduction from 2005 levels by 2020.
But representatives from other countries noted that Canada is not on track to meet its 2020 target, and raised questions about the effectiveness of measures that Ottawa recently announced to rein in emissions.

Can someone reword this so I can understand?

Canada is behind schedule in reducing greenhouse gas emissions.
