Fossil fuel emissions hit an all-time high in 2017 as carbon dioxide emissions surged for the first time in three years, climate scientists announced earlier this month.
BARCELONA, Sept 11 (Thomson Reuters Foundation) - As climate-changing emissions surge globally, a summit of world leaders this month should help revitalize ambitions to tackle climate change despite the absence of government heads from China and India, U.N. climate envoy Mary Robinson said.
Yet the country's increased coal use ― despite canceling plans for 103 new coal-fired plants ― sent global carbon dioxide emissions surging for the first time in three years, scientists announced last month.
China is one of the major contributions to the recent emission surge, and the electricity sector is the largest single source of carbon emissions, emitting approximately 40% of China's CO2 from fossil fuel combustion [1].
But energy prices would soar, the country would become dangerously dependent on Middle Eastern oil and its greenhouse gas emissions would surge if it went nuclear-free — especially if it did so immediately, said Naomi Hirose, president of the Tokyo Electric Power Company.
Japan's greenhouse gas emissions are also surging, and renewable energies such as wind and solar power remain small-scale, expensive and unreliable, the lobbying group says.
But steel mills spewing particulates into the air and sucking electricity from China's coal-fired power plants account for a big chunk of the country's surging emissions of sulfur dioxide and carbon dioxide.
But he said an ambitious, three-digit carbon tax is just one of a suite of policies needed to reduce surging emissions from burning fossil fuels, deforestation and industrial farming.
Doing so would produce another big surge in emissions of greenhouse gases, of which China is already the world's largest emitter.
Sometime in the 2020s, New Zealand will become responsible for a massive surge in emissions from its forests – just at the time when global demands for ever-deeper cuts in emissions are likely to be going into overdrive.
