Chinese President Xi Jinping has just pledged his sincere intention to contribute to the success of the Paris climate summit, but China's netizens appear far from convinced, as the smog over China's capital Beijing hits hazardous levels.
On Monday, Xi told world leaders at the COP21 summit in Paris that the country is committed to reducing carbon dioxide per unit of GDP by 60-65 percent over the 2005 level and raising the share of non-fossil fuels in primary energy consumption.
"This requires strenuous efforts, but we have confidence and resolve to fulfill our commitments," he told delegates at the conference.
He also touted the installed capacity of renewable energy in China, which accounts for 24 percent of the world totally now.
Xi's pledges have taken an ironic twist, however. While Xi has been championing China's green energy credentials, air pollution in Beijing has gone off the charts, hitting hazardous levels this week.
