CLCPA Implementation Part 1

In the summer of 2019 the Governor Cuomo and the New York State Legislature passed the Climate Leadership and Community Protection Act (CLCPA) which was described as the most ambitious and comprehensive climate and clean energy legislation in the country when Cuomo signed the legislation.  In one of the first implementation tasks the New York State Department of Environmental Conservation (DEC) has started the process to calculate a statewide Greenhouse Gas emissions (GHG) limit for this law.  This post addresses that rulemaking.

DEC Rulemaking

DEC recently released a stakeholder draft for their statewide greenhouse gas emission limit rule.  This barebone draft lists six gases that will be considered in the inventory and lists potential economic sectors that might be covered.  As part of this process DEC announced a webinar for February 14 and again on February 28 to provide the public the opportunity to learn and ask questions about the rulemaking.  During the first webinar DEC said that they would post a recording of the webinar.  If you are unfamiliar with New York’s rulemaking process the webinar provided a good summary.

Existing New York GHG Inventory

The New York State Energy Research & Development Authority (NYSERDA) works with DEC to prepare an annual inventory of GHG emissions.  The most recent report, Greenhouse Gas Inventory 1990-2016 contains a detailed inventory of historical greenhouse gas emission data from 1990-2016 for New York State’s energy and non-energy sectors.  I have been involved with all aspects of emissions inventories from developing emission factors, using inventories for air quality modeling, to preparing reports for regulatory agencies over my entire career.  I can assure you that this is a non-trivial task.  Although I have some quibbles with the NYSERDA numbers I believe that it represents New York’s emissions adequately for all purposes.

CLCPA Inventory Requirement

The CLCPA requires a report on GHG emissions, § 75-0105: Statewide greenhouse gas emissions report.  The regulation states that “No later than two years after the effective date of this article, and each year thereafter, the department shall issue a report on state-wide greenhouse gas emissions, expressed in tons of carbon dioxide equivalents, from all greenhouse gas emission sources in the state, including the relative contribution of each type of greenhouse gas and each type of source to the statewide total”.  The law specifies reductions in the future from 1990 emission levels so this section includes “§ 75-0105(5): The statewide greenhouse gas emissions report shall also include an estimate of what the statewide greenhouse gas emissions level was in 1990”.  DEC is interpreting this legislation to mean that they have to implement a new regulation that codifies the GHG emission inventory process.

It is not clear to me how much difference there is between the CLCPA inventory requirements and the methodology used for the NYSERDA report with one exception.  In particular, the legislation states that “§ 75-0105(3): The statewide greenhouse gas emissions report shall also include an estimate of greenhouse gas emissions associated with the generation of imported electricity and with the extraction and transmission of fossil fuels imported into the state which shall be counted as part of the statewide total.”  NYSERDA does not try to estimate extraction and transmission of fossil fuels emissions.

Lawmaking without Technical Expertise

I have no experience lobbying politicians to influence legislation and, frankly, have no desire to do so.  If I had been involved in this instance, I would have said that the legislation should specify the use of the NYSERDA inventory.  It has all the numbers you need, no development is necessary, and represents GHG emissions well.  Unfortunately, someone, somewhere convinced somebody to include the requirement for “an estimate of greenhouse gas emissions associated with the generation of imported electricity and with the extraction and transmission of fossil fuels imported into the state”.  At a minimum this component will have to be added to the NYSERDA inventory.  I do not know what else, if anything, DEC has deemed to be incompatible between the CLCPA law and the existing NYSERDA inventory.

As a numbers guy, I oppose including extraction and transmission emissions because the uncertainty bounds on the extraction and transmission values are large today and much worse for 1990.  In 1990 coal and oil generation was much higher than today and it is not clear to me how you could figure out the source and methodology used to extract the fuel.  The fuel specification data needed to estimate that information has been purged from company records, not only because it was so long ago but also because most of the companies who operated the 1990 facilities no longer own them.

Because including the extraction and transmission provision was a political decision, it is appropriate to discuss possible motives with the caveat that this has never been considered a skill of mine.  Clearly, including these numbers will increase the 1990 baseline and current emissions.  Note that the language says transmission and not transportation.  Coal and oil in New York are transported but natural gas is transmitted.  Therefore, my guess is that it was included by someone who wanted to make natural gas look bad by showing higher emissions.


The extraction and transmission emissions requirement has unintended consequences.  NY has a perfectly good emissions inventory but that provision means a lot of work has to be done to include those emissions. And DEC has no choice but to try to follow the requirements of the legislation.  As I noted above emissions inventories are difficult under any circumstances but when handicapped by requirements to adjust the numbers for ulterior motives the result is going to be significant effort for very little tangible benefit.

If it is correct that the extraction and transmission provisions were included by anti-natural gas advocates then I have to laugh.  I am convinced that the New York State anti-natural gas position is only supportable if the numbers are ignored or mis-understood and this is a vivid example.  In particular, the addition of extraction and transmission emissions to the 1990 baseline is going to show a larger relative decrease for coal and oil than natural gas.  Extracting coal has to be more GHG intensive than drilling and fracking a natural gas well.  Transporting the coal by rail or oil by pipeline to a refinery and then residual oil by ship or train to the power plants have much larger emissions than a natural gas pipeline to a power plant.  Worse still for the individuals who got this included is the fact that the higher baseline means that % reduction limits will also be higher.  In other words the CO2 limits will be higher so more CO2 can be emitted.
