Pulse GHGSat

Methane is the powerful greenhouse gas that’s not being talked about.

Invisible to the eye, it has 84 times the global warming potential of carbon dioxide, over 20 years.

To understand what’s happening, we first need to see it.

PULSE GHGSat is a unique interactive tool using cutting-edge technology to reveal methane concentrations around the world – in the highest resolution ever.

Easy to use interactive map lets you see concentrations of methane in the atmosphere, anywhere in the world, in the past 6 months.

ACCURATE

PULSE combines data from national space agencies with information from our own high-resolution satellites.

IMPARTIAL

Updated weekly, PULSE is a unique public resource aimed at raising awareness of this invisible, but important greenhouse gas.

Why Methane Matters

Methane (CH4) is a colourless, odourless and highly flammable gas.

Methane accounts for a quarter of all man-made greenhouse gas emissions.

Concentrations of methane in the atmosphere are increasing.

Some of the methane comes from natural processes, such as the decay of vegetation in wetlands.

The majority (c.60%) is attributable to human activity, with energy production, agriculture and waste management (landfills and dumpsites) all being major sources.
