### R. NELSON , and my mailing address is : P.O . Box 4453 , Chicago , Illinois 60680-4453 . My email address is : dennisnelson 9 87@yahoo.com . I am one of the original , modern environmental/energy activists ever since around the very first "EARTH DAY" (Wednesday , April 22 , 1970) . I have a Bachelor of Science (B . S.) Degree in Biology and Environmental Studies from Dana Co ll ege , Blair , Nebraska. I am a qualified energyenvironmental researcher , writer, speaker , and organizer. (More than 45 years ago , our climate problem was called the " greenhous e effect. " Nowadays , I prefer to call our climate crisis the more appropriately accurate phrases " human -caus ed climate disruption " or " human - made disruptive climate change ." Unfortunately , we have not taken all the necessary actions fast enough to really deal with "human-induced climate disruption"-- and the "climate clock" is ticking!) There is a SENSE OF IMMEDIATE URGENCY inherently built into our current situation WHICH REQUIRES THAT WE DO MUCH MORE OF THE RIGHT THINGS AT A QUICKER PACE . First off , I will offer MY

**CONGRAT~TIONS**

**.** Thank you for proposing the standards to maker newer heavy-duty vehicles more fuel efficient in the first place . Secondly , I will offer MY CONSTRUCTIVE CR ITIC ISM FOR IMPROVEMENT . THE "HEAVY-DUTY VEHICLE FUEL ECONOMY AND CARBON EMISSIONS STANDARDS" SHOULD BE MADE EVEN STRONGER IN ORDER TO ACHIEVE ABOUT A 40% IN FUEL SAVINGS BY 2025!! (This would use cost-effective technologies that are now being deployed or demonstrated .) An ADDITIONAL 40 MILLION METRIC TONS of cl imate- disrupting pollution would be avoided every year by 2035 , which would be equivalent to closing down around 12 coal-fired stations. Another great thing about FINALIZING EVEN TOUGHER FUEL ECONOMY STANDARDS for newer tractor-trailers , vo cational vehicles , and heavy-duty pickup trucks and cargo vans is that THEY COMPRISE A " 'NO-REGRETS' TRANSPORTATION ENERGY EFFICIENCY STRATEGY" --besides promoting climate protection , they will also have other positive benefits (like cutting our oil consumption by an additional 200 , 000 barrels each day in 2035 , reducing hazardous air pollutants from idling trucks and operating oil refineries , saving the average tractor-trai l er driver roughly $30 , 000 annually in fu el costs in 2025 , reducing the expen ses for th e owners of truck fleets , and 'driving'--pun intended !--the " 'green ' energy " innovation for i nhe rently cleaner heavy- duty vehicles). In conclusion , TAKING MY ADVICE IN STRENGTHEN ING THE F INAL HEAVY- DUTY VEHICLE ECO NOMY AND CARBON EMISSIONS STANDARDS EVEN MORE will improve our public health , ecological health , economi c well -being , and energy security . That con cl udes my testimony . Thank you !
