Several U.S. states that established ambitious climate targets for reducing greenhouse gas emissions by 2030 are now scaling back those goals amid economic and geopolitical pressures. Rising energy costs driven by global factors—including the conflict in Iran—and inflation concerns among voters have prompted some states to reconsider the feasibility and affordability of their original plans.
New York is among the most notable examples. The state had committed to a comprehensive emissions reduction target for 2030, implementing regulations across transportation, home heating, industry, and utilities. The law even granted citizens the right to sue if enforcement lagged. However, New York has fallen behind its emissions goals and in May officially abandoned the 2030 target. Governor Kathy Hochul, a Democrat, cited the significant financial burden the plan would impose on residents, describing it as “additional crushing costs.” Previously planned regulatory measures, such as a cap-and-invest program that would levy fees on polluters and return the revenue to consumers through rebates, were postponed to avoid exacerbating already high energy prices.
New York’s experience illustrates a broader trend. Nearly all states with economywide emissions targets for 2030 have struggled to keep pace with reductions, which experts say would require a 4 to 6 percent annual decrease. In reality, emissions in many states were falling by only 1 to 2 percent before the pandemic, and in some cases, even rising. The latest available data through 2023 shows this lag persists.
The combination of increased energy prices and waning policy momentum has led several states, including California, Connecticut, Arizona, and North Carolina, to ease or remove certain emissions and renewable energy goals. For instance, California’s climate regulator lowered the fees that power plants must pay under its cap-and-invest system, citing concerns about affordability.
Policy setbacks at the federal level have also complicated state efforts. The previous U.S. administration eliminated consumer tax credits for electric vehicles and heat pumps, discontinued grants for solar projects, challenged state-level pollution pricing schemes in court, halted offshore wind development, and reduced funding for electric vehicle infrastructure.
Another key reason states are struggling is their prior progress in decarbonizing electricity generation. Many states that set ambitious targets already had relatively clean power sectors, having phased out coal and increased renewables and nuclear energy. This means the "low-hanging fruit" of easy emissions reductions in electricity generation has largely been picked. Experts note that future cuts will need to come from more challenging sectors like transportation and building heating, where regulatory authority is more diffuse and coordinated efforts are harder to implement.
For example, New York’s transition away from coal was largely completed by the early 2010s, and new natural gas plants have been blocked to encourage clean energy alternatives. Even with entirely clean electricity generation, meeting the original 2030 target requires emissions reductions in transportation and buildings, which currently account for a significant share of the state’s carbon footprint. Such sectors lack centralized regulators and rely on federal incentives, many of which have recently expired.
The political debate in several states often centers on the potential costs of implementing climate policies. In New York, Republican State Senator George Borrello characterized the prior emissions goals as a failure that contributed to higher electricity costs. Conversely, Democratic State Senator Pete Harckham argued that the goals helped accelerate solar development, noting a recent $1 billion investment in solar projects. He attributed recent utility cost spikes primarily to volatile natural gas prices rather than clean energy policies.
Analysts emphasize that state-level targets alone are unlikely to achieve the reductions envisioned in agreements like the Paris climate accord without sustained federal support. Nevertheless, experts maintain that such targets offer valuable frameworks for guiding regulatory action and utility planning. Incremental progress, while insufficient on its own, is viewed as preferable to stagnation.
“It’s the deeper and more difficult cuts we need to focus on now,” said Danny Cullenward, an economist at the University of Pennsylvania. Joshua A. Basseches, a policy scholar at Case Western Reserve University, added, “Targets are so much better than nothing.”
