On Monday, the Council on Environmental Quality (CEQ) launched interim steerage for analyzing greenhouse fuel (GHG) emissions and local weather change impacts of main federal actions present process National Environmental Policy Act (NEPA) assessment.
The steerage permits for much less detailed lifetime GHG emissions analyses for renewable energy initiatives, nevertheless it additionally emphasizes new angles of research, such because the impression of floor disturbance on organic carbon shares, a subject environmental teams have usually raised over large-scale solar energy initiatives.
Overall, solar builders and their consultants ought to take care to look at CEQ’s local weather change steerage when making ready GHG research for NEPA paperwork.
The interim steerage builds upon CEQ’s 2016 NEPA steerage that was rescinded by the earlier administration. The goal of the steerage is to supply a uniform strategy for federal businesses to contemplate each the impacts of a undertaking on local weather change and the impacts of local weather change on a undertaking.
The steerage takes impact instantly whereas CEQ considers whether or not to revise or finalize it primarily based on public feedback acquired earlier than March 10.
There are a number of key parts of the interim steerage that federal businesses, builders and consultants ought to take into accout:
First, Environmental Assessments (EAs) and Environmental Impact Statements (EISs) ought to quantify GHG emissions wherever doable, each over the undertaking’s lifetime and on an annual foundation.
The steerage factors to instruments for doing so on the CEQ’s GHG Accounting Tool web site. In accordance with current federal case legislation, the steerage asserts that comparisons and fractions alone are inadequate to evaluate the impacts of GHG emissions: “NEPA requires more than a statement that emissions from a proposed federal action or its alternatives represent only a small fraction of global or domestic emissions.”

Instead, NEPA paperwork ought to embrace some type of absolute, quantitative GHG emissions estimate for the proposed undertaking and every various, together with the no-action various, aside from the “rare instance” wherein quantification is just not doable.
Second, along with quantifying GHG emissions, federal businesses ought to contextualize them comparable to by monetizing emissions utilizing the social price of carbon metric (i.e., the estimated financial prices related to every further metric ton of carbon dioxide within the environment); inserting emissions within the context of relevant local weather motion targets and commitments; or offering widespread equivalents (e.g., evaluating emissions to various households, vehicles, or gallons of gasoline burned).
The social price of carbon particularly has been the controversial topic of federal court docket choices in recent times. The rule that has emerged and is now mirrored in CEQ’s interim steerage is that the social price of carbon is an acceptable metric to research local weather change impacts beneath NEPA, however it’s not strictly required so long as emissions impacts are in any other case contextualized utilizing comparisons, widespread equivalents or foreseeable real-world results.
Third, the interim steerage directs federal businesses to research all fairly foreseeable oblique local weather change impacts of a undertaking. For instance, along with the direct GHG emissions of mining gear and transportation autos used for a coal extraction undertaking, the undertaking’s NEPA evaluation must also assess a “full burn” state of affairs and describe the GHG emissions that might outcome from downstream consumption of the extracted coal. This, too, is in line with current federal caselaw.
Fourth, the interim steerage requires particular consideration of the consequences of a undertaking on organic GHG sources and sinks along with direct ambient emissions. In truth, these “biogenic” GHG impacts are so essential that the CEQ steerage directs federal businesses to “consider developing and maintaining agency-specific principles and guidance for considering biological carbon in management and planning decisions,” and factors to the Forest Service’s present steerage for example.
This may imply, for instance, that the place a solar energy undertaking disturbs a carbon inventory comparable to topsoil, the local weather change impacts of that disturbance must be thought of within the undertaking’s NEPA evaluation – one thing for which environmental organizations have lengthy advocated.
Fifth, along with analyzing the impacts of a undertaking on local weather change, NEPA paperwork conversely ought to analyze the impression of local weather change on a undertaking by forecasting foreseeable environmental adjustments over the lifetime of the undertaking and contemplating local weather change resilience and adaptation measures.
For instance, businesses “should consider the likelihood of increased temperatures and more frequent or severe storm events over the lifetime of the proposed action” and embrace measures to handle these dangers.
Relatedly, EAs and EISs ought to think about how local weather change may exacerbate the direct results of a undertaking. For instance, “A proposed action or its alternatives may require water from a stream that has diminishing quantities of available water because of decreased snow pack in the mountains, or add heat to a water body that is already warming due to increasing atmospheric temperatures.”
Other areas of the interim steerage reiterate well-established NEPA rules, comparable to the necessity to analyze cumulative results; the requirement to research interdependent, linked actions in the identical NEPA doc; the significance of choosing acceptable options; environmental justice concerns; incorporating earlier research by reference; and implementing acceptable mitigation measures to cut back or offset GHG emissions.
Importantly for solar energy initiatives, the steerage emphasizes the “rule of reason” precept when analyzing GHG emissions, that means that the depth of research might be proportional to the general emissions of the undertaking. Low-emissions initiatives comparable to solar energy amenities can have much less detailed GHG evaluations: “The relative minor and short-term GHG emissions associated with construction of certain renewable energy projects, such as utility-scale solar and offshore wind, should not warrant a detailed analysis of lifetime GHG emissions.”
Overall, the interim steerage reinforces the significance of completely however fairly analyzing GHG emissions and local weather change impacts in federal environmental critiques and will create new alternatives for authorized problem if businesses, builders and consultants don’t take care to contemplate them throughout the NEPA course of.
