The Great AI Infrastructure Buildout: Impact on Power and Commodity Markets (Opens in a new tab)

The race to build AI-ready cloud computing infrastructure is in full swing, but a stark disconnect is emerging between announced data centre capacity and “steel in the ground.” Media and markets are expecting a rapid, exponential ramp-up of AI infrastructure. This white paper from the Oxford Smith School and Marex tells a different story: a rollout that is delayed, lumpy, and constrained by physical realities.

Impact of Oil and Gas Exploitation in the North Sea on UK Household Energy Bills – Rapid Analysis (Opens in a new tab)

A UK powered fully by renewable energy could save all households up to £441 a year on their energy bills. In comparison, maximising oil & gas extraction from the North Sea would save households a modest £16 - £82 per year - and only if the tax revenues collected were distributed to households to offset their energy bills.

Navigating risk and building resilience in the UK’s energy system: Three pillars for policy action (Opens in a new tab)

Delivering the UK’s legally binding net zero target by 2050 will require rapid, coordinated action. Despite progress, rising climate risks, system complexity and policy uncertainty threaten delivery. Strengthening system resilience is essential to meet climate, energy security and affordability objectives. This Policy Brief sets out and details actions under three high level pillars for policy action: reducing energy demand, scaling energy storage and reforming electricity markets. This Policy Brief summarises the outcomes of the ’Energy and Environment’ stream of the inaugural Oxford Policy Engagement Network (OPEN) Forum on Risk and Resilience. The 2025 Forum brought together policy professionals from multiple UK government departments and agencies, representatives from Oxford City and Oxfordshire County Councils, businesses, and funders, as well as research professionals from numerous universities and institutes in life, medical, physical, and social sciences, and the humanities.

Why and How to Include ‘Serviced Emissions’ in the updated Greenhouse Gas Protocol (Opens in a new tab)

Although progress has been made in emissions accounting for businesses, the treatment of emissions facilitated or enabled by Professional Services Providers (PSPs)  including law firms, consulting firms and advertising agencies - known as serviced emissions – remains an important policy gap.  

The Greenhouse Gas Protocol (GHGP) is the world’s leading framework for measuring and reporting GHG emissions, underpinning other climate-related standards. It is undergoing its first major revision in 20 years, creating a critical opportunity to strengthen the accuracy, coverage, and fairness of emissions accounting methodologies for organisations.

This policy brief provides three actionable recommendations to address this policy gap in the forthcoming GHGP revision, and support PSPs in accounting for serviced emissions.

UK electricity bills must be fairer, not just lower (Opens in a new tab)

Under its Clean Power 2030 target, the UK government wants to efficiently supply the country with renewables-based electricity. Achieving this requires reforms to address growing transmission constraints and regional mismatches between where renewable electricity is generated and where it is consumed.  An efficient electricity system is not necessarily a fair electricity system. Households already experience uneven retail electricity bills across the UK, with up to 15% difference by geographic location, and another 22% due to the choice of payment method or contract. Reforms that increase regional differentiation, while efficient in theory, could amplify these disparities. We need dedicated policies that address equitable bills for low-income households, to work alongside efficient and robust power market arrangements. This brief argues that a social tariff could be an effective way to protect vulnerable customers from rising costs. Paired with policies like energy efficiency upgrades, incentives for distributed energy resources, targeted infrastructure investments, and equitable transition mechanisms, this approach can ensure that market reforms deliver affordable and clean power.

Roadmap to Net-Zero Aligned Carbon Market Regulation (Opens in a new tab)

This roadmap identifies and builds on existing trends and gaps in the regulation of carbon markets and establishes six key pillars for its design or reform. It suggests that governments seeking to regulate their approach to carbon markets should first begin with identifying a clear role for carbon markets to ensure they provide an efficient and effective financing framework and align with an end state of domestic and global net-zero.

Towards a Net Zero Aligned Paris Agreement Crediting Mechanism (Opens in a new tab)

For the PACM to help rather than hinder the delivery of net zero we recommend that separate targets to reduce and remove greenhouse gases from the atmosphere be initially adopted before transitioning the mechanism to one that finances only greenhouse gas removals, and ultimately to one that finances only permanent removals.

Letter on EU 'Omnibus Simplification Package' 2025 (Opens in a new tab)

Legal scholars write to express concern regarding an amendment in the ‘Omnibus Simplification Package’ (Omnibus) proposed by the European Commission, which would significantly weaken Article 22 of the Corporate Sustainability Due Diligence Directive (CSDDD). The proposed amendment would weaken Article 22 by removing the obligation for Climate Transition Plans to be ‘put into effect’. The authors strongly advise against this proposed weakening of Article 22.

Integrating Climate and Trade Strategies (Opens in a new tab)

Policymakers face a crossroads of “megatrends” including a revived focus on industrial policy, weaponisation of trade, and climate goals that are perceived to be increasingly challenging. Export Credit Agencies (ECAs) and export-import banks (EXIMs) play a bridging role in aligning climate ambition and economic competitiveness, ensuring that export policies support both sustainability and growth.  Aligning domestic climate policies with export policies allows for the advancement of climate goals while also addressing economic growth objectives and punitive trade policies. In this Policy Brief, we develop a set of metrics to help assess whether domestic climate policy and export climate policy are aligned, and apply this to rank 19 countries with the largest ECAs, complementing our analysis with case studies of best practice.

Climate transition finance metrics effectiveness: An industry perspective (Opens in a new tab)

This study by Dr Jose Resendiz and Dr Gireesh Shrimali examines transition finance metrics reported by some of the largest global financial institutions, and conducts a global survey to assess perceptions of metric effectiveness and data availability. It uncovers a significant discrepancy: while widely adopted transition finance metrics - such as climate risk exposure and green financing metrics - are regarded as moderately to highly effective, the underlying data supporting these metrics is often incomplete or fragmented.

Financing costs and the competitiveness of renewable power (Opens in a new tab)

Relative to fossil fuel power, renewables are sensitive to changes in the cost of capital (CoC). After decades of low financing costs, interest rates have risen sharply in developed economies post-COVID19. We investigate the implications of changing CoC on the competitiveness of renewables, with impacts differing by region. In the U.S., higher rates added 18% to the levelised cost of electricity (LCOE) of solar photovoltaics’ compared to 9% for combined cycle gas turbines. However, with tax credits in the Inflation Reduction Act, solar LCOE increased by only 12%. In the future, falls in CoC will have little impact in Europe, given the high cost of fossil fuel power, but in the U.S., China, and India, differences in LCOE between certain renewable technologies and fossil fuels are minimised. Consequently, falls in interest rates or targeted policy interventions that reduce the CoC of renewables can facilitate cost parity with fossil fuels.

Assessing corporate transition plans using a production asset-based approach (Opens in a new tab)

Corporate transition plans (TPs) are increasingly seen as crucial components of assessing the compatibility and legitimacy of corporate commitments to meet climate targets. However, robust, and transparent methods to assess the credibility of disclosed TPs are lacking. Here we propose a novel open-source methodology for assessing the credibility of corporate TPs based on asset-level data to estimate CO2 emission trajectories.

Paving the way to Net Zero: A New and Credible Climate Compatibility Checkpoint for UK Oil and Gas Production (Opens in a new tab)

This policy brief proposes a robust redesign of the UK's Climate Compatibility Checkpoint for oil and gas licensing in the UK. It recommends six climate tests to align future production with net zero goals, including alignment with the Paris Agreement and UK net zero targets, clean energy investment requirements, and mandatory carbon storage. With a new government facing challenges from existing licenses, this science based framework offers a pathway to manage the sector's decline while supporting energysecurity and a just transition to net zero.
