Opponents of action to mitigate climate change often suggest that regulation could have a negative impact on jobs. But such a view may diminish the importance of other factors and obscure a fuller understanding of the big picture.
To accurately assess climate change mitigation activities, stakeholders need to consider other benefits, too. For instance, lower emissions could produce savings in the form of lower health care costs, reductions in premature death and greater well-being.
Research backs this up.
In a recent study published in Climatic Change, we examined the potential health care savings from reducing greenhouse gas emissions through different CO2-reduction activities in the United States. We found the reduction in fine particulate matter (PM2.5) pollution that would accompany such activities could result in fewer health problems, potentially saving between $6 billion and $14 billion in health care costs in 2020, depending on the activity pursued. That’s $40 to $93 in health care savings per metric ton of CO2 reduction.
These same reduction activities could yield $10 billion to $24 billion in savings if implemented more rapidly. This is because, in our rapid-implementation scenario, 40 percent of the reduction activities’ CO2 goals for 2060 are achieved by 2020, compared to 20 percent under normal implementation.
Our results also indicate that avoiding adverse health outcomes from emissions offsets the costs of implementing climate change policies.
We also looked, specifically, at the health care savings associated with increasing the efficiency of coal-fired power plants, a pillar of the new EPA rules. We found that doing so could result in nearly $8 billion in health benefits, or $13 billion under the rapid-implementation scenario.
This kind of rigorous assessment of the health impacts of climate change mitigation is essential for guiding policy decisions, particularly as EPA’s emissions rules often face significant legal challenges.
But just as jobs and emissions aren’t the only issues, there are considerations beyond the health care sector, too. It’s important to account for the full range of a given climate policy’s costs and benefits, as well as the costs and benefits of inaction.
Stakeholders should be asking about the effect of each decision on issues such as disaster preparedness and recovery, international development and aid, and agriculture and food supply, to name a few. Who wins and who loses—and by how much—under both the proposed regulation and the status quo?
The world is quickly approaching a point where the question isn’t whether to respond to climate change—it’s how. Answering that question means seeing the big picture, which can be obscured by debates operating only on the prevailing emissions-versus-jobs spectrum.
The health impacts of mitigating climate change are just one part of a complex puzzle, albeit an important one. Stakeholders need to embrace a larger policy framework if they’re ever going to piece it together.
