Emissions reduction
UK ETS costs are real. Most operators are not carrying an accurate picture of their forward exposure.
The gap between what's being reported and what's actually being emitted is wider than expected, we regularly find metering and reporting inaccuracies creating either unnecessary financial liability or compliance risk. Sigma4 brings engineering rigour to emissions work, not compliance reporting. Every reduction measure is assessed for actual carbon and financial impact. Where electrification or flare gas recovery doesn't stack up economically, we say so, and model what does.

Every measure is modelled against the financial counter-factual. We're not here to badge the asset with a net-zero pathway that doesn't add up, we're here to find the levers that move tCO₂ and ETS exposure at the same time.
Emissions baselining, ETS position & ERAP development
Platform-level Scope 1 and 2 emissions inventory, UK ETS allowance position and projected forward cost. Aligned with ERAP progression requirements. Gives leadership teams the financial exposure picture and a credible baseline against which all reduction measures are assessed and prioritised.

Decarbonisation roadmap & net zero pathway
Strategic Scope 1 and 2 decarbonisation roadmap covering all practical levers, operational, engineering and electrification. Board-level narrative on emissions performance alongside the investment case for each measure. We also provide independent business cases against electrification and flare gas recovery where the economics don't stack up.

Emissions measurement, verification & reporting
Stack emissions testing, machinery performance trials and metering audit (fuel gas, flare, water injection, produced water) to validate figures operators currently report. We establish whether current figures are fit for NSTA and DESNZ reporting. Fully outsourced emissions reporting service available.

Flaring & venting reduction study
Detailed technical review of all flaring and venting sources, continuous, maintenance, emergency and cold-vent streams, with root cause analysis and an engineering solution for each. We also challenge where purge gas optimisation creates greater environmental impact than the emissions it seeks to reduce.

A live picture of your carbon cost, not a desktop estimate.
Scope 1 and 2 emissions, allowance position, projected forward cost, against the assumptions in your ERAP. Sigma4 builds the baseline on-asset and tests each reduction measure against the actual operating envelope.
