### Re: Heavy Duty Phase 2 Greenhouse Gas Emission and Fuel Consumption Standards Good afternoon. T hank you for the opportunity to give comment today. My name is David Fink and I'm the Director of Campaigns for C limate Resolve. We are LA's climate advocacy o rganization based i n d owntown Los Ange les and we are ded icated to creating real, practical so luti o ns to meet the climate challenge whi le creat in g a better region for all Southern Ca lifornians today and in the f uture. Fir st of all, we applaud t h e Obama administration and EPA for proposing standards that will make our freight trucks cleaner and more efficient for several years go in g forward. While the proposed standards are an imp ortant step in the right direction , we urge yo u to stre ngthen these standards to ensure the greatest reductions in o il use and global warming emissions. C limate Reso lve bel ieves it is v ital that as a nation and as a state we take necessary measures that both prevent future climate change and he lp us prepare for the expected impacts. For this reason we strongly recommend the strongest possib le standards that would require heavy-duty trucks to go further on a gallon of fuel. Not only wi ll more fuel-efficient heavy-duty trucks directly reduce greenhouse gas emissions leading to a reduction in long term atmospheric warming but there are numerous benefits that will also he lp us p repare for expected climate impacts, make us more resilient and stave off the worst case scenarios. The best science we have te ll s us that Southern Cal ifornia will warm 4-5 ° Fin the middle part of this century and the number of extreme heat days will double and in some parts of the region triple. If we continue with business as usual temperatures are expected to rise an average of 9 ° F by the end of the century. However w ith strong mitigation measures we will see a leveling off of warming and a reduction of average temperatures in the l atter half of this century. Higher average temperatures and stronger heat waves will have many negative impacts maybe none more so than on public health. In a typica l year there are a greater number of mortal ities attri buted to heat than all other weather events combined. There i s also a strong correlation between heat and ground level ozone formation , meaning poorer air quality , a trigger for asthma and other chronic respiratory ai lments. Lastly, our cities already suffer from higher average temperatures than surroundi ng rural areas due to a phenomenon called the Urban Heat Island Effect wh ich typically pushes temperatures up 4-6 °

. There are three main drivers of the Urban Heat Island Effect, paved surface area (roads , rooftops, etc.) , lack of vegetation and exhaust from automobiles, trucks and manufacturing. Therefore the standards being d isc u ssed today , which will driv e down heavy-duty truck emissions , can play a significant role in help ing us coo l our cities and make us mnrP. rP.sili P. nt in thP. f::tc.P. of c.lim::ttP. c.h::tnQ'P.

.Once again, we commend the administration for proposing standards to make our trucks more efficient, and we urge you to finalize stronger standards that reduce trucks' fuel use by 40% by 2025. Thank you for the opportunity to testify. S incerely ,
