A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011. The CO 2 emissions from burning this coal will also decline by 50%.
The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data, but the overall decline of about 6% masks wide variations depending on the region and the time of year. Many economies are now seeing emissions climbing above pre-crisis levels.

Life-cycle GHG emissions per MJ of fuel produced and combusted for both 100-year and 20-year time horizons. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gasemissions are actually lower than those of conventional natural gas.
Total greenhouse gasemissions in the European Union (EU) decreased by 3.8% The large decline in emissions, achieved before the COVID-19 crisis, was mainly due to reduced coal use for power generation. This decrease brought EU emissions to 24.0% from 2018 to 2019.

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. emissions are less important because of the low contribution of light duty vehicles to national PM 10 and PM 2.5
Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.
Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. Preparing the US for the impacts of climate change. Earlier post.).
The US Environmental Protection Agency (EPA) has proposed Clean Air Act standards to reduce CO 2 emissions from fossil-fuel fired power plants (electric utility generating units, EGUs). The proposed rulemaking establishes separate standards for natural gas and coal plants.
An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.
Stroll, play, talk, celebrate -do whatever you want on the public street without sucking up gas fumes or fearing for your life from drunk drivers, texting drivers, drivers eating or putting on makeup or just plain dangerous behind the wheel lunatics. It’s long been time to kick coal out of L.A.’s
One possible scenario for the electricity system in the Western US in 2026-29. Their analysis also found that current renewable portfolio standards (RPS) are insufficient to meet emission reduction targets by 2030 without new policy. To meet these carbon goals, coal has to go away from the region. Click to enlarge.
All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.
However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. In both plants, natural gas turbines power the equipment. Upstream emissions are emissions, including from leaks and combustion, from mining and transporting a fuel such as coal or natural gas.).
While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University.
