This policy brief argues that the current reliance on a single 100-year metric for greenhouse gas emissions obscures the distinct warming impacts of methane and carbon dioxide. The author advocates for a "multi-basket" approach with separate targets and dual metrics to address both short-term and long-term climate risks, asserting that simultaneous mitigation of both pollutants is essential to meet global temperature targets and reduce climate overshoot.

This briefing by Zero Carbon Analytics examines the potential and limitations of using soil carbon sequestration, specifically through regenerative grazing, to offset greenhouse gas emissions from livestock. While some estimates suggest significant carbon uptake potential, the document argues that these gains are often overstated because they fail to account for the finite capacity of soil, the reversibility of carbon storage, and the potent warming effects of methane and nitrous oxide emitted by ruminants.

The Americas Conference on Solar Radiation Modification, held in August 2022 in Kingston, Jamaica, served as a regional forum to introduce the science, governance, and implications of Solar Radiation Modification (SRM). The event brought together scientists, policymakers, and representatives from various Americas nations to discuss SRM as a potential supplement to climate mitigation, emphasizing the need for inclusive research, regional collaboration, and a risk-risk framework to evaluate the technology's potential benefits against the dangers of unchecked global warming.

This amicus brief, submitted by the Center for International Environmental Law and other organizations, argues that United States import prohibitions on shrimp harvested without turtle excluder devices (TEDs) are consistent with WTO rules. The brief contends that these measures are justified under GATT Article XX as necessary for the conservation of endangered sea turtles, a goal supported by international environmental law and the principles of sustainable development.

This document is a formal statement of objection submitted by Louise Vandelac and Marie-Hélène Bacon on behalf of the Canadian Association of Physicians for the Environment. It challenges the decision RDV2017-01 by Health Canada's Pest Management Regulatory Agency (PMRA/ARLA) to renew the registration of glyphosate-based herbicides (GBHs) for approximately 15 years. The authors argue that the scientific basis for the decision is outdated, overly reliant on confidential industry data, and ignores recent independent research regarding human health, food contamination, and environmental impacts.

This briefing note by the International Institute for Sustainable Development (IISD) discusses Canada's ratification of the Minamata Convention on Mercury and the current state of mercury management in Canada, with a specific focus on Ontario. It outlines scientific assessments of mercury as a neurotoxin, the role of the IISD-Experimental Lake Area (IISD-ELA) in mercury research, and the international and domestic regulatory frameworks governing mercury emissions, releases, and waste management.

This briefing note from the Stockholm Environment Institute examines the scientific and political complexities of 'loss and damage' within the UNFCCC framework. It analyzes four key traits—attributability, irreversibility, unavoidability, and intolerability—to clarify the gap between risk management approaches and calls for climate justice and compensation.

This policy brief, published in November 2011 by UNESCO, SCOPE, and UNEP, examines the scientific, policy, and ethical implications of geoengineering (climate engineering). It distinguishes between carbon geoengineering and solar geoengineering, outlines a four-stage research framework, and highlights the urgent need for an international governance framework to manage the risks and equities associated with large-scale climate manipulation.

This report by the World Resources Institute argues that current carbon market crediting systems systematically undervalue tropical forests by focusing exclusively on carbon sequestration and ignoring critical non-carbon biophysical effects that contribute to global climate stability.

This report by the World Resources Institute argues that current carbon credit markets systematically undervalue tropical forests by focusing exclusively on carbon sequestration and ignoring critical non-carbon biophysical effects that contribute to global, regional, and local climate cooling.
