Ember is an independent climate think-tank focused on accelerating the global electricity transition


To accelerate the global electricity transition from coal to clean.


Theory of change

Data into action: we gather, curate and analyse data on the global coal to clean transition, with a focus on the power sector. 

We use our data and analysis to:

Support high impact, politically viable policies that accelerate the coal phase-out.

Empower campaign organisations.

Shape the global narrative on coal.

Wind and solar are ready to lead the global coronavirus recovery

As countries start entering Covid-19 recovery phases, governments are presented with a unique opportunity to step up wind and solar investment. This briefing compares the wind and solar industries in different regions of the world, and shows why wind and solar are ready for the big time.

Ember's Board

Bryony Worthington

Harry Benham

Harry Benham

Harry is Chair of the Board. An energy industry professional for over 30 years with BP, Shell and EY. Also Strategic Advisor on energy issues with CarbonTracker Initiative.


Ember’s roots go back to 2008, when Baroness Bryony Worthington saw the desperate need to shine a light on the malfunctioning EU carbon market.

Founded as Sandbag Climate Campaign, we enabled the public to buy and remove the surplus carbon allowances from the EU Emissions Trading System (EU ETS). Recognising the systemic problems with the carbon market, we quickly transitioned into data-driven policy advocacy, aiming to win reform of this crucial climate policy.

Previous campaign successes

The Lignite Cash Cow – Highlighting the falling profits of German lignite plants, and tackling coal company arguments for excessive compensation 

Limiting coal capacity payments: Winning a 550gCO2/kWh emissions limit, preventing European coal plants from receiving Capacity Payments from 2025.

The Last Gasp: Ongoing success revealing the health burden from European coal plants, winning new legislation to reduce power plant air pollution.

Maintaining the UK Carbon Price Support: coalition building, joint letters with industry, to maintain the UK’s top-up carbon tax and rapidly phase-out coal.

Annual European Power Sector Review: Shaping the narrative each year on the European electricity transition.

EU ETS Phase 4 reform: The key green voice in the debate which implemented the MSR and took the EU carbon price from €2 to €30.

    • removing hundreds of millions of ‘unused allowances’ from the oversupplied EU ETS
    • winning the introduction of the Market Stability Reserve, to lock away surplus allowances
    • helping to secure a ban on polluting HFC offset credits
