Carbon Tracker
Tracking Great Britain's energy carbon dioxide - from electricity, gas and transport fuels - and how many hours each year the grid runs at the government's 2030 clean power target.
UK energy CO2 by sector, per month
Monthly CO2 from burning energy in Great Britain, split with no double-counting into electricity generation, gas for heating and industry, and oil broken down by end use - road, aviation, heating and other. It shows how small the power sector's emissions now are next to heating and transport. How this is calculated.
Hours of electricity at the 2030 target, per year
Total hours in each calendar year when GB electricity carbon intensity met the 2030 target. The count rises as more wind, solar and nuclear displace gas - years with higher renewable output typically score more hours. The most recent year may be incomplete.
Cumulative hours of electricity at the 2030 target, by year
How the cumulative count of hours at the target builds through the year, compared across years since 2016. Steeper lines indicate periods of low-carbon generation - typically high wind and solar months. Comparing years shows how the grid is improving over time.
