    Clean energy commitments like CESs are trending across the country with states, cities, and utilities, as the new interactive dashboard and I put together shows. Play around with it yourself!

    Like we get it, we obviously need to re-enter the Paris Agreement. What else do you have?

    After watching 2 nights of dem debates, it is clear that we need a . I want to hear actual plans. We are talking about MAJOR changes in every single sector of our economy.

    Going through all of this, 1 thing is abundantly clear to me - we have a massive challenge in front of us & are well beyond the time to pick and choose favorite solutions. We need every single carbon-free technology that can help us meet our goal - 0x50. End.

    SO. We have our work cut out for us. No 1 single policy is going to eliminate or offset every single one of these sources of emissions. We are going to need tailored solutions for all sectors of the economy using a variety of policy levers. 19/

    Land Use, Land-Use Change, and Forestry (LULUCF) 🌲🏞️: A net sink of emissions in the US, offsetting ~11% of emissions each year. If we enhance our carbon sinks, we could offset up to 14% of emissions in 2025, according to Rhodium Group. 18/

    Other⛏️🗑️: Remaining emissions are best broken down into different GHGs. The largest amount comes from substitution of ozone-depleting substance, non-energy use of fuels, landfills, & coal mining. When we say net-zero, it means addressing/offsetting all of these sources. 17/

    Oil&Gas⛽️: These are emissions associated with the production of fossil fuels - mainly methane emissions from natural gas systems. Preventing methane leakage from wells & pipelines will help significantly reduce these emissions. 16/

    Buildings🏢🏠: Most of the carbon pollution from buildings comes from electricity use. But there are emissions that come from burning fossil fuels onsite, typically for space & water heating, shown below. Electrifying heating & retrofitting buildings will be key. 15/

    Improved soil, manure, and livestock management can help significantly cut ag emissions, but realistically, we will need to offset some of these emissions that we can’t eliminate. 14/

    Agriculture 🌽🐄: The production of livestock and crops for food results in the release of 3 GHGs - Non-combustion CO2 comes from nitrogen fertilizer, CH4 from cattle & sheep & manure management, &N20 emissions from soil management practices. 13/

    That’s a lot, but the good news is that around 0.5% of all US manufacturing facilities (960 plants) produce 25% of industrial emissions, so that is a great place to start. 12/

    Addressing emissions from these sources will require carbon capture, new materials & processes, & climate-friendly HFC alternatives & replacing old equipment. 11/

    Remaining 23% of industry emissions comes from 1) chemical reactions from transforming raw materials into products like cement or ammonia, & 2) the production & use of HFCs used in refrigeration, air-conditioning, etc. These emissions can be broken down into GHG & sub-sector. 10/

    Replacing these fossil fuels with carbon-free fuel sources is difficult because many industrial processes require high temps & consistent sources of energy, so wind and solar aren’t always suitable replacements. 9/

    Industry 🏭: ~77% comes from combustion of fossil fuels like nat gas & petroleum for process energy (i.e. heating for furnaces, kilns, & dryers). These emissions can be broken down into more than a dozen sub-sectors, with refining & chemicals as the top 2 emitters. 8/

    We must innovate clean liquid fuels & replace vehicles with electric/hydrogen-powered vehicles. EVs are only 0.5% of new car sales...if we wanted all new sales to be EVs within 10 years, that needs to ⬆️by ~9% each yr. Avg. fleet turnover rate is ~20 yrs 7/

    Transportation ✈️🚘🚃🚢: Light-duty vehicles (pickups, SUVS, and cars) are responsible for the largest chunk of transpo emissions (59%). That’s coming from approx 250 million gasoline-powered passenger 🚗s. 6/
