2. Key Findings

There was a 4% increase in production compared with 2017

14.63 million tonnes of CO 2 e were emitted, maintaining a stable level of total emissions over the past five years 74% CO 2 emissions were from power generation

3%

Upstream oil and gas operations contributed of total UK GHG emissions

UKCS carbon intensity (CO 2 decreased from 23 kt/million boe to 21 kt/million boe

emitted per unit of production)

Methane emissions increased by 800 tonnes compared to 2017 – contributing 1.22 million tonnes CO 2 e

1.2 million tonnes of gas were flared (3.5 million CO 2 e), a 7% decrease on 2017 Produced water discharged to sea fell by 3% from 143 million m 3 to 139 million m 3 over the past five years

The volume of produced water reinjected increased 11% to 60 million m 3

Concentrations of dispersed oil in produced water discharged remains below the 30mg/l limit, at 16.1mg/l

Average Ra-226 concentration and average total NORM concentration remains significantly below the 0.1Bq/ml limit
