The Climate Implications of New Oil and Gas Fields in the UK
– An overview of the evidence
This report reviews the latest scientific evidence and other scholarly literature on the climate implications of new oil and gas extraction projects. The policy implications for the UK are:
The UK Government’s policy of ending new oil and gas licensing is necessary to align with the Paris goals.
Fully aligning with the Paris goals also requires the further step of refusing development consents for already-licensed fields such as Rosebank. The report’s findings are directly relevant to the decision the Secretary of State must make regarding the significant effects on the environment of new oil and gas projects for which development consent is sought.
These policies have the ability to influence actions by other governments, while strengthening the UK’s reputation as a climate leader.
The best outcome for jobs and the economy is to focus all new energy investments on renewable energies, while production from existing oil and gas fields declines.

A Legally Sound Oil and Gas Phase-out
At the 28th United Nations Climate Change Conference (COP 28), governments agreed to transition away from fossil fuels in a just, orderly, and equitable manner. Some governments are implementing this decision with plans to phase out oil and gas production. One of the barriers to phase-out policies is the threat of investor–state arbitration. This report provides policy-makers with tools to mitigate the legal risks of investor–state arbitration when designing oil and gas phase-out policies.

Response to DESNZ Consultation on Scope 3 Emissions Guidance
In a landmark decision, the British Supreme Court ruled in Finch v Surrey County Council that planning authorities must assess "downstream" greenhouse gas emissions as part of the environmental impact assessment (EIA) process for fossil fuel projects. The case specifically concerned oil extraction at Surrey's Horse Hill site, where planning permission was granted without considering emissions from burning the extracted oil (Scope 3 emissions).

Transitioning Away From Oil and Gas
A production phase-out primer
At the COP 28 climate summit in Dubai, 198 governments agreed to transition away from fossil fuels. That means phasing out oil and gas, as well as coal. Yet most oil and gas producers plan to drill more, not less. Some countries are dependent on revenues from oil and gas, or politically entangled with the industry. An unmanaged transition could get ugly. So how do we deliver a fast, fair, and orderly phase-out?

No New Fossil Fuel Projects
The logical first step in a transition to clean energy
At the 28th UN Climate Change Conference (COP 28) in Dubai last year, the world’s governments agreed to “transition away from fossil fuels in energy systems, in a just, orderly and equitable manner.” But how can this transition be achieved, when fossil fuels are so embedded in people’s everyday lives, in the global economy, and in powerful political interests?

No new fossil fuel projects: The norm we need
The groundbreaking decision at COP28 calls on parties “to contribute to…transitioning away from fossil fuels in energy systems.” Yet, the global production and use of fossil fuels continue to expand, making the goals of the Paris Agreement ever more difficult to achieve.
This Policy Forum article argues that proponents of ambitious climate action should focus on stopping new fossil fuel projects, encompassing exploration for and development of new fossil fuel extraction sites, and permitting and construction of new, large-scale fossil fuel–consuming infrastructure. Specifically, the article argues that governments should ban new fossil fuel projects, and civil society should advocate such bans. Together, these efforts would help to build a global “No New Fossil” norm.

An Equitable Phaseout Of Fossil Fuel Extraction
Towards a reference framework for a fair and rapid global phaseout
This report proposes a framework for equitably phasing out fossil fuel extraction based on five principles:
1. Stop extraction when it violates human rights,
2. Phase out global extraction at a pace consistent with the 1.5 °C limit,
3. Enable a just transition for workers and communities,
4. Reduce extraction fastest in countries least socially dependent on fossil extraction,
5. Share transition costs fairly, according to capacity to bear those costs.
It specifies phaseout timeframes grounded in shared equity principles and the particular national circumstances of extracting countries, and makes an initial assessment of the nature and scale of the climate finance and international support that can make these timeframes achievable.

Petrostates of Decline
This report, an update of our 2021 Beyond Petrostates report, finds that petrostates are facing substantial risks from the energy transition, as falling oil and gas demand is set to put downward pressure on commodity prices and place future government revenues in jeopardy.
While a small handful of countries have reduced their vulnerability, overall the 40 petrostates we analyse are just as vulnerable as in our original analysis and in many ways face growing risks.
This update is driven by two key factors: the growing socio-economic challenges confronting petrostates and the availability of new data reflecting the impact on energy markets from recent geopolitical events. We apply a least-cost methodology used in our previous report to reassess how the energy transition could affect different petrostates.

How quickly does the world need to 'phase down' all fossil fuels?
India and China were widely criticised at COP26 in 2021 when they pushed to tone down the language on coal consumption that emerged from the climate summit. As a result of this intervention from two highly coal-dependent nations, with the covert support of other key players, the final version of the Glasgow Climate Pact only called on nations to "phase down" rather than "phase out" unabated coal power.

Socio-political feasibility of coal power phase-out
Its role in mitigation pathways
In IPCC pathways limiting warming to 1.5 °C, global coal power generation declines rapidly due to its emissions intensity and substitutability. However, we find that in countries heavily dependent on coal—China, India and South Africa—this translates to a national decline twice as rapid as that achieved historically for any power technology in any country, relative to system size. This raises questions about socio-political feasibility.
Here we constrain an integrated assessment model to the Powering Past Coal Alliance’s differentiated phase-out timelines of 2030 in Organisation for Economic Co-operation and Development/European Union and 2050 elsewhere which, for large coal consumers, lies within the range of historical transitions. We find that limiting warming to 1.5 °C then requires CO2 emissions reductions in the global North to be 50% more rapid than if this socio-political reality is ignored. This additional mitigation is focused on Europe and the United States, in transport and industry and implies more rapid decline in global oil and gas production.

Existing fossil fuel extraction would warm the world beyond 1.5°C
The Paris climate goals and the Glasgow Climate Pact require anthropogenic carbon dioxide (CO2) emissions to decline to net zero by mid-century. This will require overcoming carbon lock-in throughout the energy system. Here we make the first bottom-up assessment of committed CO2 emissions from fossil fuel-producing infrastructure, defined as existing and under-construction oil and gas fields and coal mines.
We find that staying within a 1.5 °C carbon budget (50% probability) implies leaving almost 40% of 'developed reserves' of fossil fuels unextracted. The finding that developed reserves substantially exceed the 1.5 °C carbon budget is robust to a Monte Carlo analysis of reserves data limitations, carbon budget uncertainties and oil prices.
This study contributes to growing scholarship on the relevance of fossil fuel supply to climate mitigation. Going beyond recent warnings by the International Energy Agency, our results suggest that staying below 1.5 °C may require governments and companies not only to cease licensing and development of new fields and mines, but also to prematurely decommission a significant portion of those already developed.

Countries Must Phase Out Oil and Gas Production
—and Quickly
How fast do we need to phase out fossil fuels to achieve the goals of the Paris Agreement and safeguard our planet’s future? This question is central to planning effective climate action.
IISD commissioned climate scientists at the Tyndall Centre at The University of Manchester to help answer this question, especially in relation to oil and gas production. Their new report suggests a faster timeline than many governments are planning: an oil and gas production phase-out by 2034 for rich countries, and by 2050 for the poorest.

The Production Gap Report 2021
This report first introduced and quantified the “production gap” in 2019, finding that the world’s governments planned to produce far more fossil fuels than consistent with their Paris Agreement commitment to limit global warming. Two years on, with the climate crisis clearer and more urgent than ever, governments continue to bet on extracting far more coal, oil, and gas than is consistent with agreed climate limits.
Specifically, this report’s production gap analysis — the first full update since 2019 — finds that the world’s governments still plan to produce more than double the amount of fossil fuels in 2030 than would be consistent with limiting global warming to 1.5°C, and 45% more than consistent with limiting warming to 2°C. Collectively, although many governments have pledged to lower their Figure ES.1 emissions and even set net-zero targets, they have not yet made plans to wind down production of the fossil fuels that, once burned, generate most of those emissions.

National Oil Companies and Climate Change
Insights for advocates
National oil companies (NOCs) are key players in the global oil and gas industry—they produce half of the world’s oil and gas, and invest 40% of capital into the sector. But policy-makers and climate activists alike often overlook NOCs’ role in global efforts to address climate change. Omission of NOCs from climate strategies will significantly hamper governments’ attempts to meet global climate goals, and NOCs—along with the countries that depend on their revenues—could be left behind.

Equity, climate justice and fossil fuel extraction
Principles for a managed phase out
Equity issues have long been debated within international climate politics, focused on fairly distributing reductions in territorial emissions and fossil fuel consumption. There is a growing recognition among scholars and policymakers that curbing fossil fuel supply (as well as demand) can be a valuable part of the climate policy toolbox; this raises the question of where and how the tool should be applied. This paper explores how to equitably manage the social dimensions of a rapid transition away from fossil fuel extraction.
This paper begins by reviewing how extraction affects economies and communities and the different transitional challenges they face. Based on that review, it then examines three common equity approaches – economic efficiency, meeting development needs, and effort-sharing.

The IEA and climate change
The International Energy Agency (IEA) is the world’s most influential source of energy information. Its stated aim is to support decisions in governments and in the private sector, “to ensure reliable, affordable and clean energy.”
To achieve this, it must advise governments and others on how to address the biggest energy challenge of the twenty-first century: preventing dangerous climate change. All 30 of the IEA’s member countries have signed the Paris Agreement, committing to keeping warming well below 2 degrees Celsius above pre-industrial levels, and pursuing efforts to keep it to 1.5 degrees Celsius.
However, in this report we find that the IEA is holding governments back from achieving those goals. The IEA’s roadmap “New Policies Scenario” (NPS), the foremost guide to decisions on energy policies and investments, steers those decisions towards levels of fossil fuel use that would cause severe climate change

Forecasting Failure
Why investors should treat oil company energy forecasts with caution
Companies like ExxonMobil, Shell and BP routinely use their in-house energy forecasts to justify investments in multi-decade, high-cost projects, from the Arctic to the tar sands. While the companies present their published forecasts as objective analyses, the forecasts rather reflect the future they want us to believe in. This report:
reveals the poor track record of oil company forecasting;
exposes the unlikely assumptions built into the forecasts; and
examines the consequences of these forecasts for investments and for climate change.
It finds that the companies are highly vulnerable to disruption by clean energy technologies, and that their forecasts are playing an unhelpful role in the climate debate. The report includes a comparative analysis of the oil majors’ current approaches to thinking about energy futures, and recommendations for more robust ways to think about the future of energy, echoing the recent Task Force on Climate-Related Financial Disclosures.

Flawed Fundamentals
Shell's and BP's stalled tar sands ambitions
While the circumstances for rapid expansion of the tar sands were favourable for the industry over the past two decades, there are clear signs that pro-expansion conditions such as unfettered market access, stable high oil prices, political and public support, growing U.S. demand and minimal regulatory constraints have shifted.
Since 2014, 42 tar sands projects have been put on-hold, delayed, or cancelled. The matrix of risks that have stalled the predicted unchecked growth of the tar sands combine to suggest structural rather than cyclical changes in the oil industry and represent a significant setback to the oil companies’ frontier driven growth model.

The climate impact of the proposed crude-by-rail terminals in the Pacific Northwest
In this report , OCI deploys the oil industry’s own forecasting and modeling tools together with a detailed examination of the Northwest facilities’ configurations. Key findings in the report concern:
Propping up Canadian tar sands: In the absence of new pipelines, Northwest rail terminals would be the sole driver of new growth in Canadian tar sands oil.
Multiplying oil extraction and climate pollution: Oil train facilities in the Northwest could unlock as much as 382,000 barrels per day of new tar sands production that would otherwise not be extracted. The resulting greenhouse gas pollution from extra tar sands production could be as much as 106 million metric tons per year of carbon dioxide—the equivalent of doubling the total greenhouse gas pollution of Washington state.
Feeding the Bakken beast: Northwest oil train terminals could also lead to more oil drilling in the Bakken formation, as much as 114,000 barrels per day beyond what would be produced without the terminals. The resulting greenhouse gas pollution from this extra production could be as much as 30 million tons per year of carbon dioxide—the equivalent of doubling the number of cars on the road in Oregon and Washington.

Turbo-Charging Investor Sovereignty
Investment Agreements and Corporate Colonialism
Multilateral negotiations are stalling. Unable to get what they want, corporations are now relying on bilateral and regional treaties to push their investment interests. They are using Bilateral Investment Treaties (BITs) to challenge national and local laws, taxes and other government actions, or to push through new obligations such as more intellectual property rights.
Some companies are using existing or specially-negotiated BITs to get more out of concession agreements. Under the umbrella of BITs, companies are imposing Host Government Agreements (HGAs) that dictate the legal framework under which a company's proposed project, such a dam or an oil pipeline, will operate. The Agreements give effective control to a company over national legislation and regulations that apply to their activities -- and require the country to compensate the corporation if it enacts any new law that affects corporate profits.
This article describes and illustrates how corporations are imposing a new era of resource colonialism by means of these agreements with examples from the former Soviet Union, West Africa and Iraq.
