State parks provide us with beautiful, accessible spaces to connect with nature – but the lands they protect often also serve as major carbon storage hubs. Keeping these lands wild is a key line of defense against a changing climate. https://t.co/t6HJZkYbbj

State parks aren’t just for weekend getaways. By preserving forests, wetlands, grasslands and other natural areas, many of these much-loved places act as vital carbon sinks that help to regulate our planet’s health. https://t.co/t6HJZkYbbj

In 2016, only 13 U.S. states had grid-connected battery energy storage. In 2025, only 13 states did not have battery storage, while the leading state, California, has seen a >100-fold increase in battery storage since 2016. https://t.co/GV3f6WEybX

Three quarters of the permitted diesel generators at Virginia data centers are older, more highly polluting “Tier 2” models. Federal and state laws are plagued with loopholes that could allow their expanded use beyond real emergencies. https://t.co/c6Smkx4SPA

[Frontier Group @FrontierGroupUS]

Data centers around the country rely on dirty diesel generators for backup power in case of emergencies. But with increasing strain on the grid, pressure to expand their use is mounting. Our new resource explains. https://t.co/c6Smkx4SPA

Lack of funding has left many states struggling to keep up with the everyday maintenance and repairs needed to keep their state parks in good condition. Our new report outlines a set of measures that can help turn this around. https://t.co/0NNHvsXWqp

[Frontier Group @FrontierGroupUS]

State parks are a gateway to nature for millions of Americans, but lack of investment has left many operating with facilities and infrastructure in dire need of repair. Our new report examines what can be done to tackle the backlog. https://t.co/0NNHvsXWqp

[Frontier Group @FrontierGroupUS]

State parks are loved by millions, but many parks don’t have the funds they need to keep on top of basic maintenance and repairs. Our new report examines the scale of the current repair backlog and suggests measures for tackling it. https://t.co/0NNHvsXWqp

The EPA is proposing a rule change that would enable “chemical recycling” plants to emit more harmful pollution with less federal oversight. This brings major risks for our communities, our environment and our health, as we explain here: https://t.co/MjlI0diIIx

Some of the oldest and dirtiest power plants in the nation are staying online to help power data centers. 17 power plants with delayed retirements were responsible for more than 3% of NOx and SO2 pollution from the U.S. electricity sector in 2023. https://t.co/M3n9AdM8XN

[Frontier Group @FrontierGroupUS]

In 2023, power plants with delayed retirements emitted about 33,000 tons of sulfur dioxide and nearly 30,000 tons of nitrogen oxides, more than 3% of all such pollution reported to the EPA that year. https://t.co/M3n9AdM8XN
