美国运输部正在为一项新的基础设施投资和就业法案计划开放，该计划在五年内授权了64亿美元的项目，以减少运输来源的碳排放。新利18备用网址
The IIJA was signed into law on Nov. 15, but its new programs, including the one aimed at trimming carbon emissions, were bottled up until a full-year 2022 appropriations package was enacted on March 15.
In formally kicking off the Carbon Reduction Program on April 21, DOT Secretary Pete Buttigieg said in a statement, “As the sector generating the most carbon emissions in the U.S. economy, transportation must play a leading role in solving the climate crisis.”
DOT的联邦公路管理局（FHWA）发布了该计划的五年逐州资金分配。加利福尼亚州排名第一，其5.55亿美元，其次是德克萨斯州，其6.41亿美元和佛罗里达州为3.2亿美元。
宾夕法尼亚州排名第四，拥有2.65亿美元；伊利诺伊州排名第五，拥有2.26亿美元。
该计划的2022年总体授权是《基础设施法》的第一年，约为12亿美元。
FHWA also released a memorandum to outline how the program will be implemented.
各种各样的项目类型都有资格获得减少碳资金的资格，包括行人和骑自行车的人的越野步道，公共汽车快速运输线，智能运输系统和为电动汽车充电的基础设施，或为氢，天然气或丙烷提供动力的汽车。
Also eligible are purchases of zero-emission construction equipment and vehicles and projects that speed the flow of traffic but do not include constructing lanes to add road capacity.
各州必须将其减少碳减少计划资金的年份65％“分配”到司法管辖区，范围从少于5,000的人口到人口超过200,000的城市化地区。该子分类应与其州总人口的相对份额成正比。
But the memo says states can use "other factors," with U.S. DOT approval.
该计划为各州和其他收件人提供了碳计划的资金，以实质性的灵活性来使用美元。
For example, the program and funds fall under the Federal Highway Administration but states and other jurisdictions can "flex," or transfer, them to be used on projects that fall under the Federal Transit Administration's responsibilities.
The program also requires states to draw up carbon reduction “strategies,” by Nov. 15, 2023, though funds for carbon-reducing projects can flow before the plans are completed.
倡导集团SmartGrowth America运输策略助理副总裁史蒂夫·戴维斯（Steve Davis）说，减少碳释放计划，而IIJA则是“混合袋子”。
Davis told ENR via email, "It is absolutely a notable and important step forward that Congress has devoted significant funds to projects that are aimed at reducing emissions."
他补充说：“但是没有真正保证这些资金会导致衡量的[温室气]排放，因为国会赋予各州的广泛纬度，使各州轻松地将这些美元完全从计划中转移出来，或者将它们用于具有可疑利益的项目新利18备用网址用于减少排放。”
众议院运输和基础设施委员会的共和党高级批评FHWA指导备忘录。
委员会的最高共和党人和罗德尼·戴维斯（Rodney Davis）（R-ill。），高速公路和过境小组委员会的排名GOP成员罗德尼·戴维斯（Rodney Davis）（R-Rodney Davis（R-ill。尽管这项政策与国会在最近的基础设施法中的意图直接冲突，但他们可能需要建造新的道路。”
委员会中的戴维斯，格雷夫斯和其他共和党人敦促政府取消较早的指导备忘录，该备忘录涉及IIJA中其他FHWA计划的备忘录。
