With negotiators about to start international climate talks, you might have missed a notable climate effort at the state level: A new report from Maryland’s Department of the Environment shows the state is on track to beat its goal of reducing its emissions 25 percent below 2006 levels by the year 2020.
Since that goal was set in 2009, Maryland has implemented a range of programs to reduce emissions from the energy sector, transportation, agriculture, and buildings. The state also benefitted from changes in energy markets as power generators moved from coal to natural gas, and changes in driving behavior, with Marylanders driving fewer miles than forecast.
Additionally, Maryland participates in the nine-state Regional Greenhouse Gas Initiative (RGGI), a cap-and-trade program that has generated revenues the state has used to help thousands of low- and moderate-income families and hundreds of farms improve efficiency and save money on their energy bills.
Maryland isn’t the only state that has set ambitious targets to curb greenhouse gases. According to our research, 18 other states have set targets over the past 15 years. Eight states, Maryland among them, stand out as leaders for setting targets by legislative action or executive order, requiring progress reports and updates of original climate plans, and aggressively pursuing initiatives to achieve the targets.
Why are states acting?
Already, Maryland and other states are experiencing the types of impacts — excessive heat, droughts, heavy downpours — expected to become more frequent and intense as a result of climate change. No one individual weather event can be attributed directly to climate change; climate is a pattern of events over time. However, it is clear that the costs to property, crops, and public health from impacts consistent with climate change are already significant.
A series of C2ES briefs explores key climate impacts and estimates how they might affect Maryland’s heat-related mortality, coastal property, labor productivity, energy expenditures, and agricultural output as well as its infrastructure, tourism, ecosystems, water resources and human health beyond heat-related mortality.
Climate scientists tell us that even deeper emissions reductions are necessary in the coming decades to avoid more serious and costly impacts. Recently, the Maryland Climate Change Commission, a government advisory board, unanimously recommended that the state set a new goal to cut its emissions 40 percent by 2030. The recommendation, supported by additional C2ES analysis, is likely to be taken up in the General Assembly next year.
Maryland cannot tackle climate change alone. But by working to reduce emissions today, setting strong reduction targets for the future, and growing a clean energy economy, Maryland is creating a powerful example other states will want to follow.
