ITF: worldwide transport activity to double by 2050, emissions to rise 16% compared to 2015

Green Car Congress

According to the ITF Transport Outlook 2021 , the biennial flagship report of the International Transport Forum, a sister organization of the OECD, global transport activity will more than double by 2050, and traffic emissions will rise by 16% compared to 2015 even if existing commitments to decarbonize transport are fully implemented.

OECD: governments should make better use of energy taxation to address climate change; “meaningful” increases limited to road sector

Green Car Congress

In 2015, outside of road transport, 81% of emissions were untaxed, according to the report. Tax rates were below the low-end estimate of climate costs (EUR 30/tCO 2 ) for 97% of emissions. The report assesses the magnitude and coverage of taxes on energy use in 2015, and considers change between 2012 and 2015.

MIT report finds China’s actions on climate change crucial; argues for global economy-wide greenhouse gas tax

Green Car Congress

A new report from the MIT Joint Program on the Science and Policy of Global Change shows the importance of all major nations taking part in global efforts to reduce emissions—and in particular, finds China’s role to be crucial. C change by the end of the century. Without China, we miss that mark by about 1 °C.

California ARB approves 2017 Climate Change Scoping Plan; requires doubling the rate of GHG cuts

Green Car Congress

The California Air Resources Board unanimously approved the 2017 Climate Change Scoping Plan , which sets the state on an aggressive course to reduce greenhouse gas emissions an additional 40% below 1990 levels by 2030 under SB 32. This will require California to double the rate at which it has been cutting GHGs. Earlier post.).

Georgia Tech study projects potential mixed impacts of climate change policies on air quality

Green Car Congress

They used the EPA US 9-region national database (EPAUS9r) with the MARKet Allocation (MARKAL) energy system model to develop emissions scenarios and spectral nudging to downscale global climate to the regional scale over the US. The GISS ModelE2 provides the initial and boundary conditions to a regional climate model for the years 2006?2010
