Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.
The technology group Wärtsilä has issued a report ahead of COP26, the UN’s Climate Change Conference to be held in Glasgow this autumn, describing the environmental and economic opportunities for states that decarbonize rapidly. Remaining fossil fuel capacity can then be rapidly phased-out, if it has not already been retired.
“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds. —Howarth and Jacobson.
The legislation also proposes numerous actions against financing and support for fossil fuel industries. Imported fuels and products would also be charged the same carbon fee that domestic fuels and products play, unless the exporting nation has similar climate program and already charges a fee on carbon. Debt reduction.

The people whose business model is to wreck the ecology and the climate and profit from it. These are the people who in the face of science that says we must transition from fossil fuels to renewable energy or destroy the futures of our children and all who come after them, still want to drill for oil that should never be burned.
And the people who are MY heroes and the ones I consider our greatest patriots today are on the front lines fighting climate change. . But hold them up I do because their work – like the work of the the scientists, activists, organizers, volunteers and other climate hawks I admire, enlightens and inspires me to do the work I do.
Fuel cycle analysis (FCA)—or “well-to-wheels analysis”—is a type lifecycle analysis (LCA) that examines fuel products and their supply chains, and that has greatly influenced climate-related research priorities and public policies for transportation fuels.
conversion to fuel molecules or to electrons—depends on market and regulatory contexts that are outside the scope of attributional life cycle assessments (LCA). suggested that converting biomass into electricity for EVs abates more GHG emissions than does converting biomass into liquid fuels for use in today’s conventional vehicles.
Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. —Mark Jacobson. In both plants, natural gas turbines power the equipment.
This year’s edition highlights the growing divergence between demands for action on climate change and the actual pace of progress on reducing carbon emissions. Coal consumption (+1.4%) and production (+4.3%) increased for the second year in a row in 2018, following three years of decline (2014-16).
