AQLI: new data reveals little progress globally in reducing air pollution over the last two decades

Green Car Congress

Particulate air pollution continues to cut global life expectancy by nearly two years as progress in some countries counterbalances worsening air quality in others, according to the Air Quality Life Index (AQLI). China began a “war against pollution” in 2013.

Air pollution is the leading environmental cause of death worldwide according to the State of Global Air 2018 , the annual report and interactive website published by the Health Effects Institute (HEI). Ozone, another important component of outdoor air pollution, whose levels are on the rise around the world, contributed to 234,000 deaths from chronic lung disease. coal, wood, and dung) for cooking and heating. million early deaths from outdoor air pollution in 2016.

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 decline was driven by a surge in shale gas supplies and more attractive renewable power that displaced coal. Coal demand fell worldwide but the drop was particularly sharp in the United States, where demand was down 11% in 2016.

Global CO2 emissions stalled for the third year in a row

Green Car Congress

Emissions are increasing in other developing countries: 6% for Indonesia and Malaysia; 9% for Pakistan and 12% for the Philippines. CH 4 is mainly generated by agricultural activities, the production of coal and gas, as well as waste treatment and disposal. The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO 2 emissions have stalled for the third year in a row.

The report also covers an assessment of the potential contribution from reductions in short-lived climate pollutants (SLCPs). Avoiding new coal-fired power plants and accelerated phasing out of existing plants—while ensuring careful handling of issues such as employment, investor interests and grid stability—would help the emissions picture. There are an estimated 6,683 operating coal-fired power plants in the world, with a combined capacity of 1,964 GW.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

While carbon dioxide is the primary driver of global warming over the long term, limiting black carbon and methane are complementary actions that would have a more immediate impact because these two pollutants circulate out of the atmosphere more quickly. The team considered about 400 emission control measures to reduce these pollutants by using current technology and experience. Iran, Pakistan and Jordan would experience the most improvement in agricultural production.
