IEA finds CO2 emissions flat for third straight year even as global economy grew in 2016

Green Car Congress

This was the result of growing renewable power generation, switches from coal to natural gas, improvements in energy efficiency, as well as structural changes in the global economy. The biggest drop came from the United States, where carbon dioxide emissions fell 3%, or 160 million tonnes, while the economy grew by 1.6%.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Reducing emissions from diesel engines and domestic wood and coal fires is a no-brainer, as there are tandem health and climate benefits. —co-author Professor Piers Forster from the University of Leeds’s School of Earth and Environment in the United Kingdom.

UN report finds world needs incremental $1.9 trillion invested in green technologies to avert planetary catastrophe; global per capita cap on primary energy consumption of 70 GJ/yr may be required

Green Car Congress

The past decade was the first in two centuries with increasing CO2 emissions intensities, owing to a “coal revival”, in contrast with the rapid conversion to natural gas in the 1990s. These trends, which are diametrically opposed to declared greenhouse gas mitigation goals and targets, are by no means limited to emerging economies.

IEA World Energy Outlook view on the transport sector to 2035; passenger car fleet doubling to almost 1.7B units, driving oil demand up to 99 mb/d; reconfirming the end of cheap oil

Green Car Congress

In the 450 Scenario, oil demand falls between 2010 and 2035 as a result of strong policy action to limit carbon-dioxide (CO2) emissions; oil demand peaks before 2020 at just below 90 mb/d and declines to 78 mb/d by the end of the projection period, over 8 mb/d, or almost 10%, below 2010 levels. —WEO 2011.

Study Concludes That to Limit Global Warming to 2 °C, Less Than 25% of Proven Fossil Fuel Reserves Can be Burnt Between Now and 2050

Green Car Congress

Shown are fossil CO2 emissions (top panel) and corresponding global warming (bottom panel). The researchers, involving scientists from Germany, the United Kingdom and Switzerland, concluded that the limit is 1,000 billion tonnes of carbon dioxide between the years 2000 and 2050.
