EPA主要使用两个遗留的IT系统来管理部落、州和地方空气监测机构收集的室外空气质量数据。这些系统的数据有助于识别不符合空气质量标准的地区,并向公众传达有关空气污染水平的信息
The Intergovernmental Panel on Climate Changes’ (IPCC) Sixth Assessment Report (AR6) has delivered another wakeup call about the need for drastic cuts to greenhouse emissions by 2035 to avoid the most devastating impacts of climate change to human well-being and ecosystems. Carbon dioxide (CO2) may be the most well-known greenhouse gas (GHG), but others, known as non-CO2 or short-lived climate pollutants, also have a critical role to play in keeping the Paris Agreement’s 1.5 degrees C (2.7 degrees F) temperature goal within reach, while also improving air quality and protecting health. , Short-lived climate pollutants — methane, black carbon and hydrofluorocarbons (HFCs), which are also sometimes known as “super pollutants” — remain in the atmosphere for less time than carbon dioxide but have a potent impact on near-term global warming. For example, methane has more than 80 times the warming power of CO2 in its first 20 years in the atmosphere. And about 45% of today's net global warming is driven by methane emissions from human activities. Moreover, methane is also a precursor for another powerful driver of climate change: tropospheric (ground-level) ozone.
作为恢复、转型和复原计划的一部分,PREE建筑能源改造计划的预算从最初的3亿欧元增加到2021年7月的4.025亿欧元。这比最初为2020年至2023年分配的3亿预算增加了35%。该计划包含在西班牙恢复和复原计划的第二部分中。
