Climate Action for Today and Tomorrow: The Relationship between NDCs and LTSs
The document argues that while NDCs (short-to-medium term commitments) and LTSs (mid-century visions) serve different legal and functional roles, they should be developed synergistically. Aligning them prevents the 'lock-in' of carbon-intensive infrastructure and reduces administrative costs by sharing data, modeling, and stakeholder consultations. The authors suggest that ideally, an LTS should inform the NDC, though they provide options for countries developing both in parallel or those updating NDCs without a formal LTS.

Deeper Decarbonization in the Ocean State: The 2019 Rhode Island Greenhouse Gas Reduction Study
The 2019 Rhode Island Greenhouse Gas Reduction Study finds that the state can feasibly reduce emissions by 70-80% by 2030, 2040, or 2050 by focusing on electrification, efficiency, and transitioning the power grid to renewables. The report updates previous 2016 baseline estimates, finding that 2017 emissions were approximately 45% higher than previously thought due to updated science on methane leakage and its short-term global warming potential. While substantial reductions are possible, the study notes that pathways stall at around 4 million metric tons of carbon dioxide equivalent, leaving a 20-30% gap that requires further research into industrial decarbonization and carbon sequestration.

Deeper Decarbonization in the Ocean State: The 2019 Rhode Island Greenhouse Gas Reduction Study
The report finds that Rhode Island can feasibly reduce its greenhouse gas emissions by 70-80% by 2030, 2040, or 2050 by focusing on electrifying transportation and heating, improving energy efficiency, and transitioning the electricity grid to renewables. A critical finding is that updated science on methane leakage from natural gas infrastructure reveals that 2017 emissions were approximately 45% higher than previously estimated in 2016. While the 2050 pathway is relatively low-cost, the 2030 pathway requires a significant spending spike, resembling a 'Green New Deal' approach. The study emphasizes that reaching net-zero requires the complete phase-out of natural gas and further research into industrial decarbonization and carbon sequestration.

Re: Tacoma LNG Project, & Proposed Order of Approval No. 11386
The document argues for the denial of the Tacoma LNG project, claiming it locks Washington into 40 years of fossil fuel dependence and poses significant safety and health risks. It asserts that the project's purpose has shifted from peak-shaving for utility customers to primarily serving as a marine and trucking fuel source, necessitating a new environmental review. The authors contend that the Puget Sound Clean Air Agency (PSCAA) has underestimated greenhouse gas emissions by relying on flawed assumptions regarding methane leakage and the 'no-action' alternative. Additionally, the document highlights failures in the Final Environmental Impact Statement (FEIS) to address recent LNG disasters, cumulative toxic air emissions in a densely populated urban area, and environmental justice impacts on the South Sound community and the Puyallup Tribe.

Written Evidence Treasury Select Committee Inquiry into Decarbonisation of the UK Economy and Green Finance
ClientEarth argues that HM Treasury (HMT) is an obstacle to ambitious climate policy and lacks transparency in its coordination with other departments. The submission calls for a 'Climate Cabinet' and a parallel climate budget to ensure legal targets are met. In the financial sector, ClientEarth highlights a widespread failure among pension funds and asset managers to treat climate change as a material financial risk, noting a 'herd mentality' that stifles innovation. It criticises the Financial Conduct Authority (FCA) for a lack of enforcement regarding climate risk disclosures and warns of 'greenwash' in sustainable financial products. The document recommends mandatory TCFD reporting for large asset owners by 2022 and the regulation of investment consultants by the FCA.

WHOLESALE ELECTRICITY MARKET DESIGN FOR RAPID DECARBONIZATION: A DECENTRALIZED MARKETS APPROACH
The authors propose a market design featuring a regional spot market operated by an independent Regional Transmission Organization (RTO) using locational marginal pricing and security-constrained economic dispatch. To ensure long-term investment in clean resources and manage price risk, the model relies on decentralized bilateral contracts, such as Power Purchase Agreements (PPAs), rather than centralized capacity procurement. The authors contend that this approach facilitates the retirement of fossil fuel generation, promotes innovation in distributed energy resources, and minimizes political interference. They emphasize that public policy instruments, such as carbon pricing or portfolio standards, should complement this market structure by internalizing greenhouse gas externalities to accelerate the transition.

WHOLESALE ELECTRICITY MARKET DESIGN FOR RAPID DECARBONIZATION: VISIONS FOR THE FUTURE
The paper argues that current wholesale electricity markets, designed for large fuel-burning plants with high production costs, are ill-equipped for a future dominated by wind, solar, and storage, which have near-zero production costs and different operational characteristics. It identifies a disconnect between federal wholesale rates and state retail rates as a barrier to demand-side flexibility. The authors propose ten principles for modern markets—including technology neutrality, grid reliability, and long-run efficiency—and outline two emerging pathways for reform: a "Robust Spot Market" approach focusing on decentralized bilateral contracting, and a "Long-Term Plus Short-Term Markets" approach utilizing a centralized forward market.

WHOLESALE ELECTRICITY MARKET DESIGN FOR RAPID DECARBONIZATION: LONG-TERM MARKETS, WORKING WITH SHORT-TERM ENERGY MARKETS
The document examines the risks that current short-term wholesale electricity markets, based on locational marginal prices (LMPs), may fail to provide sufficient price signals to sustain the investment needed for deep decarbonization. This is primarily due to the minimal short-run marginal costs of variable renewable energy (VRE) and the fact that VRE resources often cannot capture scarcity prices during production lulls. To mitigate this, the authors propose long-term markets that provide contractual certainty through power purchase agreements (PPAs) or similar mechanisms. The report compares three specific proposals (by Corneli, Gimon, and Pierpont), identifying six core commonalities: the use of long-term contracts, voluntary participation, coordination with short-term markets, incremental implementation, optimized policy guidance, and organic implementation pathways. The authors suggest that these long-term markets can better identify efficient portfolios of VRE, storage, and flexible load across broad regions, reducing the risk of overbuild or incompatible resource mixes.
