Portfolio carbon accounting and SREC valuation for private company portfolios. We measure what you emit, what your generation is actually worth in the market it can be sold into, and what closing the gap costs.
A 525 MWh solar array produces 525 renewable certificates. What those certificates are worth depends entirely on which market they are sold into - and most owners have never checked.
Sold as voluntary RECs
$4,200
525 x $8 - typical voluntary market
Sold into NJ compliance
$110,250
525 x $210 - NJ SREC benchmark
Difference
$106,050
same electrons, different market
Same generation. Same year. A 26x spread, driven only by which state's compliance obligation the attribute can serve. Eligibility is not automatic and not every array can reach every market - but the assessment tells you which ones yours can, before you sign a long-term offtake that prices them at voluntary rates.

Indicative 2025 secondary-market benchmarks aggregated from SRECTrade, Karbone and PJM-GATS. These are planning figures for scoping, not a quote, not a bid, and not a solicitation to buy or sell an environmental attribute.
Grid emissions use EPA eGRID 2023 subregion factors. Fuel, travel and process factors use the EPA GHG Emission Factors Hub. Certificate prices use aggregated secondary-market benchmarks, refreshed quarterly and overridable with your own authoritative price file.
Renewable generation is credited once. If you retain the attribute you get the avoided tonnes; if you sell it you get the revenue and the tonnes go with the buyer. Counting both is the most common error we find in portfolio carbon reporting, and it is the one that fails diligence.
No emissions factor, price or tonnage on your report is invented. Every figure traces to a published source, cited inline, and we will show you the arithmetic.

Fixed fee, scoped before it starts. No percentage of certificate revenue, no success fee, no commission on anything you transact. We are paid for the measurement, which is the only way the measurement stays worth reading.
