Building smarter climate policy
Explore our work

Who we are

We are a think tank conducting data-driven and evidence-based advocacy to improve EU climate policy.

We combine expertise in decarbonisation with data analysis to propose policies that drive impactful, cost-effective emissions reductions in the EU and beyond. Through our holistic approach, we make sure our recommendations are not only well-informed and effective but also inclusive, considering economic and geostrategic realities.

Our story

  • 2008: Sandbag was founded in London, to reveal flaws in the EU Emissions Trading System (ETS) and develop solutions for its surplus of carbon allowances.
  • 2013: Opening of an office in Brussels, to reinforce our influence on EU policy.
  • 2018: Sandbag officially became a non-profit organisation under Belgian law (ASBL).
  • 2019: After Brexit, the UK-based entity was renamed Ember, while Sandbag focused only on EU climate policy.

Since 2019, we have strengthened our focus on EU decarbonisation policies, leveraging our expertise in carbon markets and data analysis. Today, our data tools and technical insights are trusted by policymakers and media – across Europe and beyond.

Our work

Publications

We provide evidence-based and data-driven recommendations for smarter climate policies through in-depth research on EU decarbonisation policies, from carbon markets to industrial emissions reductions.

Data tools

We develop advanced tools to model emissions, track EU policy impacts, and test decarbonisation scenarios. These in-house tools ensure that our research is both accurate and actionable, helping EU decision-makers implement efficient climate policies.

Advocacy

 We advocate climate policies that deliver real emissions reductions through collective networks of think tanks and NGOs, by participating in public consultations, in European Commission Expert Groups or by engaging directly with stakeholders and policymakers.

Electrification or electrical decarbonisation? We need both!

Sandbag’s response to the EU’s Electricity Action Plan highlights why both electrification and power sector decarbonisation are essential. It warns that growing electricity demand risks cannibalising clean power, unless renewable deployment accelerates.

Sandbag’s Response to the CBAM Calls for Evidence

Sandbag has submitted responses to the EU’s CBAM calls for evidence, addressing emissions reporting, adjustment for free allocation, and carbon prices paid abroad. We highlight risks such as loopholes and unequal treatment, and propose practical solutions to strengthen CBAM’s effectiveness and fairness.

CBAM impact on US trade: an analysis

Sandbag’s September 2025 research note explores the impact of the EU’s CBAM on US exports. It finds that even with expanded scope, the financial impact remains marginal — and US carbon pricing could turn net costs negative.

The EU CBAM: A Two-Way Street to Climate Integrity?

Sandbag’s latest report examines how the EU’s CBAM will impact third country exporters. While some may reduce costs through resource shuffling, real emissions may remain unchanged — calling for stronger alignment through carbon pricing.

State Aid for Indirect Carbon Costs: Reform before extending!

Sandbag responds to the EU’s consultation on State aid for Indirect Carbon Costs (ICC), calling for targeted reforms to better support clean electricity, avoid windfall profits, and align with the Carbon Border Adjustment Mechanism (CBAM).

Our team

Our team blends diverse backgrounds, technical skills, and a shared commitment to advancing decarbonisation with evidence-based policies. Each member contributes unique expertise—from carbon markets and industrial decarbonisation to clean hydrogen and advanced data analysis.

Our supporters

Our work is supported by foundation grants and individual donations from those who share our commitment to advancing effective climate policies. We also occasionally undertake consultancy work that aligns with our mission to drive efficient emissions reductions.

We thank all our supporters for enabling our efforts to strengthen EU climate policy and, in doing so, contributing to the fight against climate change.
