That is half two of a two-part evaluation that unpacks the EU and the UK’s shift away from the Power Constitution Treaty (ECT), specializing in the Treaty’s misalignment with local weather targets and the continuing challenges associated to fossil gas investments.
On December 3, the Power Constitution Convention adopted its proposal for modernizing the Power Constitution Treaty (ECT). Beforehand, and in response to the shortcomings of the modernized textual content, the EU and the UK took a daring step by withdrawing from the Treaty. These choices have been a important first step, signaling that fossil-related local weather measures should take priority over continued funding advantages to fossil fuels. Nevertheless, whereas these withdrawals are a landmark achievement, addressing the entrenchment of fossil fuels is way from over. Two important challenges persist that would undermine the targets of the Paris Settlement: the ECT’s controversial “sundown clause” and the advantages supplied to fossil fuels investments and the continued use of investor-State dispute settlement (ISDS) mechanisms underneath different treaties.
The “sundown clause” dangers extending fossil gas protections for one more 20 years, and international locations are nonetheless certain by different outdated funding obligations. The query stays: how can we break away from the grip of fossil gas funding safety and safeguard the long run?
The problem of how governments can overcome these obstacles is exacerbated by a number of elements:
Quite a few States stay Events to the ECT
There are greater than 2,800 bilateral funding treaties (BITs) (about 2,200 at present in pressure) and 450 treaties with funding provisions (TIPs) (about 390 in pressure) that present related advantages and obligations and allegedly bolster fossil gas investments.
Fossil gas investments are additional entrenched by long-term funding contracts and home legal guidelines.
Consequently, the issue extends far past the ECT — it’s a systemic situation rooted within the present international funding regime that poses challenges in aligning with the implementation of worldwide local weather targets and obligations.

The necessity to align funding treaties with the Paris Settlement has gained rising recognition, notably by the Intergovernmental Panel on Local weather Change (IPPC) in 2022 and in stakeholder engagements carried out by the UNFCCC Standing Committee on Finance in 2023. The IPCC highlights that “[i]nvestment agreements, which are sometimes built-in in FTAs, search to encourage the circulate of international funding by funding safety. Whereas worldwide funding agreements maintain potential to extend low-carbon funding in host international locations, these agreements have tended to guard investor rights, constraining the latitude of host international locations in adopting environmental insurance policies.”
Funding treaty safety advantages, usually considered as a safeguard in opposition to political dangers, can present buyers with compensation for financial losses and facilitate the enforcement of funds. Whereas these advantages, provided with out price to buyers, assist fossil gas investments by mitigating monetary dangers — they inadvertently bolster fossil gas investments. This poses quite a few challenges to implementing local weather obligations and is at odds with Article 2.1(c) of the Paris Settlement, which requires aligning monetary flows with local weather targets. Eradicating these treaty advantages would assist align and redirect monetary flows towards cleaner power investments, making certain higher compliance with local weather commitments and advancing international decarbonization efforts.
The ECT’s sundown clause is a provision in Article 47(3) that permits treaty protections to stay in impact for as much as 20 years after a rustic withdraws. Which means that throughout that interval, fossil gas investments made earlier than such withdrawal profit from funding protections, and governments threat being sued by investments for implementing insurance policies that affect these tasks.
This clause creates an “entrenchment impact” by binding governments to outdated obligations — limiting governments’ skill to be launched from their treaty obligations instantly — and additional exposes them to ISDS–associated dangers. Consequently, buyers can submit claims in opposition to a State earlier than an arbitral tribunal underneath the ECT after its withdrawal and inside the survival interval.
For instance, regardless of withdrawing from the ECT in 2016, Italy confronted an ISDS declare over its ban on coastal oil drilling. The final result was a multimillion-dollar award in favor of the UK firm Rockhopper, underscoring the monetary dangers of the sundown clause.
Within the context of the EU and UK withdrawals from the ECT, the appliance of the sundown clause would lengthen advantages to the fossil gas trade as much as at the least 2043 (if not longer for some EU States) — a timeline that’s far past a 2030 agenda and present local weather obligations and commitments. There may be additionally the chance that in this sundown interval, buyers will scale up their actions to maximise revenue, making present projections even worse.
For ECT withdrawing events, addressing the legacy problems with the ECT has grow to be a prime precedence. On June 25, 2024, EU Member States signed a declaration and preliminary inter se settlement clarifying that the ECT’s investor–State arbitration provision doesn’t apply — and by no means has — to intra-EU funding disputes.
Whereas these steps make clear the inapplicability of the ECT’s investor–State arbitration mechanism inside the EU, they don’t stop legacy arbitrations between the EU and the greater than 20 non-EU ECT Contracting Events. Due to this fact, an inter se settlement is required between the EU, the UK, and the remainder of ECT Members. Just lately, the European Financial and Social Committee, a consultative physique of the EU gathering representatives from commerce unions and civil society organizations, urged the EU to pursue an inter se settlement with the UK and different third international locations to neutralize the ECT’s sundown clause. This transfer is taken into account vital for aligning with the European Inexperienced Deal, mitigating the legacy dangers related to the ECT, and addressing potential challenges funding arbitration may pose to local weather motion. It’s promising to see this situation gaining momentum and being highlighted as a precedence for the subsequent European Fee.

Whereas there are lots of points associated to the remaining ECT Members — even in a modernized type — the ECT is only one piece of a bigger puzzle. Hundreds of BITs and treaties with TIPs stay in pressure, lots of which embrace sundown clauses and ISDS mechanisms that proceed to bolster fossil gas investments and make it tough for States to totally implement fossil gas climate-related measures with out the chance of dealing with authorized and monetary repercussions. For instance:
Turkey (an ECT Member) has a BIT with France (Turkey-France BIT 2006) that will enable Turkish buyers to provoke ISDS in opposition to France underneath related grounds as underneath the ECT.
Germany alone has 120 BITs (114 are in pressure) and 78 TIPs (63 are in pressure).
Italy has 65 BITs (52 are in pressure) and 79 TIPs (64 are in pressure).
Spain has 68 BITs (60 are in pressure) and 78 TIPs (63 are in pressure)
The UK has at the least 96 BITs (85 are in pressure) and 33 TIPs (26 are in pressure).
Importantly, the fossil gas trade operates inside a deeply interconnected market and may discover methods to discussion board buying. Traders may choose to look past the EU altogether and set up operations in international locations that aren’t contemplating withdrawal from the ECT or which might be events to different regional or bilateral agreements.

For instance, EU Member States made a big step in 2020 by terminating 190 intra-EU BITs by a single termination settlement. Total, whereas this regional reform is commendable and marks a noteworthy place to begin, it doesn’t totally resolve key points. One vital limitation is that it leaves a possible loophole for discussion board buying, because the termination solely impacts intra-EU BITs and doesn’t lengthen to different funding agreements that EU Member States have with third international locations. Within the context of the EU, an investor from an EU Member State equivalent to Spain might have investments in France. Provided that there is no such thing as a longer an intra–EU BIT, the investor can’t provoke ISDS proceedings in opposition to France. In that case, the investor may restructure their funding by establishing an organization in Turkey and transferring their investments from France to Turkey, a non–EU nation.
This is without doubt one of the many examples that exemplify {that a} piecemeal technique — the place particular person international locations or areas implement their very own remoted measures — is akin to placing a Band-Support over a bullet gap. To successfully cope with the problem, a coordinated international method is required to make sure the harmonization of insurance policies throughout nations and align the worldwide funding panorama with local weather commitments and obligations.
Apart from the challenges posed by the sundown clause, there are States that stay within the ECT and others getting into into the ECT. The latter pattern is rising, particularly amongst creating international locations. This improvement places in danger their local weather motion and exposes these international locations to ISDS claims which will cripple their economies.
Though the EU and UK withdrawals are anticipated to decrease the ECT’s membership, the ECT Secretariat has been actively looking for to broaden its membership, significantly concentrating on creating international locations in Africa, Asia, and Latin America. To date, South Africa has been vocal about not becoming a member of the ECT, with a former authorities official stating that “[i]t is a very dangerous thought for any African nation to contemplate signing as much as this specific treaty,” however far more motion is required.
Apart from the ECT, States are certain by a community of hundreds of agreements that present related authorized results to the ECT. Nevertheless, a globally coordinated method to align these agreements with local weather commitments and obligations is urgently wanted and possible. Present reform processes are insufficient, as they fail to handle substantive points or take piecemeal approaches, leaving important gaps that enable for continued fossil gas protections and ISDS dangers.
UNCITRAL Working Group III: The United Nations Fee on Worldwide Commerce Legislation Working Group III on Investor-State Dispute Settlement Reform (UNCITRAL WGIII) has been the first physique tasked to handle ISDS reform for the final decade. Nevertheless, UNCITRAL Working Group III has confronted criticism for its gradual progress and restricted scope in delivering substantial reforms.
The group’s focus has primarily been on procedural enhancements — equivalent to enhancing transparency, consistency, and impartiality in arbitration — slightly than on the extra basic adjustments wanted to handle broader or substantial considerations, together with local weather change. Political and procedural complexities stemming from the varied pursuits of taking part States have slowed the tempo of reforms, leaving stakeholders annoyed with the method and lack of tangible outcomes after a number of years of discussions. Key climate-related points, such because the safety of fossil gas investments, have been unnoticed of the reform agenda.
UN Commerce and Improvement (UNCTAD): UNCTAD’s efforts to reform worldwide funding agreements have made some progress, however a lot of this reform has occurred on the bilateral degree, with international locations negotiating treaty-by-treaty adjustments. This fragmented method has made it tough to realize widespread, coordinated reforms that handle international challenges like local weather change, because the amendments usually stay restricted to particular person treaties and not using a cohesive worldwide technique. These treaty-by-treaty amendments have did not create a cohesive worldwide technique, usually leaving fossil gas protections largely untouched.
The World Commerce Group (WTO): Some WTO Members have been actively engaged in creating an Funding Facilitation for Improvement Settlement. This settlement seeks to boost funding facilitation procedures and processes amongst its members, selling a extra conducive setting for funding flows. Whereas the initiative goals to streamline rules and enhance transparency in funding processes, its scope primarily focuses on procedural enhancements slightly than addressing the substantive points surrounding funding regarding international challenges, together with local weather change.
The Group for Financial Co-operation and Improvement (OECD): Way forward for Funding Treaties Monitor 1 (Funding Treaties and Local weather Change) has acknowledged the necessity for funding agreements to be aligned with international local weather targets, particularly in gentle of worldwide commitments such because the Paris Settlement. Nevertheless, regardless of ongoing efforts and proposals to terminate agreements, carve out fossil fuels from the scope of worldwide funding agreements (IIAs) or ISDS provisions, or suggest different local weather carve-outs, these makes an attempt haven’t materialized on the OECD.
Addressing Limitations Imposed by the Sundown Clause and ISDS Dangers
To handle the limitation imposed by the sundown clause and ISDS dangers, in addition to the fragmentation and inadequacy of present reform processes, governments ought to take into account extra coordinated and complete funding regulation regime reforms.
First, Events to the ECT can discover the choice of concluding an inter se settlement to neutralize the sundown clause. This authorized instrument, permitted underneath Article 41 of the Vienna Conference on the Legislation of Treaties, permits a bunch of events to a multilateral treaty to change the treaty’s software amongst themselves, supplied that the modification doesn’t have an effect on the rights of different events or the general function of the treaty.
The neutralization of survival clauses in IIAs just isn’t with out precedent. For instance, Argentina and Indonesia reached a mutual settlement to terminate their BIT, reportedly neutralizing the sundown clause by mutual settlement earlier than withdrawing from the treaty. Within the context of the ECT, an inter se settlement affords a viable and politically possible method to neutralizing legacy arbitration dangers between the EU and non-EU ECT contracting events. IISD, with the assist of CIEL and different authorized consultants, has ready a mannequin inter se settlement for the modification of the ECT.
Second, some international and regional initiatives reveal the potential to reform funding frameworks. Nevertheless, they present {that a} coordinated technique is critical to keep away from coverage and reform fragmentation and be sure that substantive issues are addressed in a coherent and complete method inside the funding regulation regime.
Regardless of a rising consensus on the necessity for reform, present reform processes are fragmented, resulting in completely different approaches and scopes. The various mandates and priorities of various negotiating boards additional complicate the coordination or integration of ISDS reform. Due to this fact, if the world goes to cut back its reliance on fossil fuels and meet its local weather targets, a extra proactive method might be required within the realm of funding agreements and ISDS.
The ECT and its sundown clause are symptomatic of a broader situation: the misalignment of worldwide funding frameworks with local weather targets. The local weather emergency additionally requires pressing motion. We wouldn’t have the time to amend agreements one after the other. Effectivity, predictability, and coherence name for States to work collectively to search out one answer as a substitute of utilizing sources to maintain engaged on a piecemeal method.
Which Resolution Can Be Efficient?

Worldwide arbitration tribunals are certain by the phrases of funding treaties or contracts, giving them the mandate to resolve particular disputes. Precedents present that tribunals don’t all the time give vital weight to mushy regulation and even judicial choices. The one efficient solution to modify the obligations set by a global settlement is thru one other worldwide settlement that applies between the events and that retrofits into current treaty obligations.
This method just isn’t completely new. For instance, in 2020, EU Member States terminated all 190 intra-EU BITs by a single termination settlement. Related coordinated actions on IIA termination are rising in different areas. In Africa, States collaborated on IIA coverage and not too long ago negotiated the African Continental Free Commerce Space Funding Protocol, which requires terminating current intra-African BITs — together with their sundown clauses — inside 5 years of the Protocol’s entry into pressure.
Moreover, the authorized mechanisms required to amend current treaties at the moment are well-established, with a number of profitable examples to attract upon.
Most not too long ago, in September 2023, the OECD and the G20 Inclusive Framework on Base Erosion and Revenue Shifting concluded negotiations on the Multilateral Conference to Facilitate the Implementation of the Pillar Two Topic to Tax Rule. Like the sooner 2016 OECD multilateral tax treaty, this new conference permits events to include agreed adjustments into quite a few current tax treaties. The 2016 OECD conference has seen vital adoption, with over 1,900 tax treaties matched for reform as of February 2024.
Within the realm of funding agreements, a multilateral or plurilateral settlement presents a viable answer to handle key points in a world, complete, and coherent manner. Such an settlement may very well be crafted as an inclusive framework, which permits for constant and harmonized obligations throughout numerous jurisdictions. Key options must also:
Be legally binding: Safeguards have to be legally binding to make sure that these measures are relevant between States. This entails creating clear, enforceable authorized provisions that stop the initiation of claims associated to focused measures, thus securing regulatory house for environmental and human rights obligations. Furthermore, it might be sure that ISDS claims focused measures are dismissed as early as potential, stopping pricey and protracted arbitration.
Rooted in science and worldwide local weather and human rights obligations and commitments: Any reform have to be straight linked to worldwide local weather and human rights obligations and grounded within the newest scientific information, equivalent to that supplied by the IPCC and different authoritative sources.
Successfully take away funding advantages to fossil gas investments: Provided that fossil fuels are the main reason for the local weather disaster, contributing considerably to international warming and environmental degradation, the settlement ought to be sure that fossil gas investments not obtain the advantages supplied by funding agreements, together with funding promotion, or recourse to arbitration in opposition to States underneath ISDS mechanisms. This could even be essential to make sure that monetary flows are aligned with the targets of Article 2.1(c) of the Paris Settlement.
Instantly relevant: The settlement ought to enter into pressure instantly for any nation that ratifies it with out the necessity for a selected variety of ratifications. This could guarantee swift motion and forestall undue delays in addressing the present misalignment between the advantages that States present to fossil gas investments and their local weather obligations.
If wanted, begin as plurilateral frameworks with the goal to be multilateral: If a multilateral root just isn’t accessible within the brief time period, the trail ahead may contain initiating a plurilateral settlement with the long-term objective of reaching a multilateral framework. The settlement may set up key ideas and authorized mechanisms and lay the muse for broader, multilateral adoption, making a cohesive and globally coordinated framework that may successfully handle the local weather disaster. The success of the Paris Settlement, which began with a coalition of keen events, demonstrates the potential of this method, which could be relevant within the context of funding regulation reform.
The EU and UK withdrawals from the ECT are a milestone in local weather motion, however the struggle to align funding agreements with local weather obligations and commitments has solely simply begun. Addressing the sundown clause and the widespread community of funding treaties that favor fossil gas pursuits requires pressing, coordinated international motion. Inter se agreements and multilateral or plurilateral options provide sensible pathways to neutralize legacy protections and realign international funding insurance policies with the pressing wants of the local weather disaster.
The local weather emergency requires structural reform. By putting local weather priorities over entrenched funding protections, the world can break away from fossil gas dependencies and pave the best way for a sustainable future. This shift would require daring management and a dedication to insurance policies that promote clear power and environmental integrity over fossil gas investments.
