The richest one percent of the world's population are responsible for more than twice as much carbon pollution as the 3.1 billion people who made up the poorest half of humanity during a critical 25-year period of unprecedented emissions growth, according to a new study by the aid group Oxfam. The report, "Confronting Carbon Inequality," is based on research conducted with the Stockholm Environment Institute and has been released as world leaders prepare to meet at the UN General Assembly to discuss global challenges including the climate crisis. The report assesses the "consumption emissions" of different income groups between 1990 and 2015—the 25 years when humanity doubled the amount of carbon dioxide in the atmosphere. It found:

The Innu Nation of Labrador announced Oct. 6 that it is seeking $4 billion in damages from Hydro-Quebec over its mega-dam on the Upper Churchill River. The suit, filed in the Supreme Court of Newfoundland & Labrador, seeks compensation for the theft of ancestral Innu land in 1967 to build the Churchill Falls hydro-electric project, leading to devastation of their community's culture and way of life. "The impact of Churchill Falls has been felt across generations of Innu. What happened, it was not right. Our elders deserved better treatment then, and we demand better treatment now," said Grand Chief Etienne Rich. He charged that Hydro-Quebec and the provincial utility in Newfoundland, now called Nalcor Energy, "stole our land and flooded it in order to take advantage of the enormous hydro potential of the Churchill Falls. This project was undertaken without consulting us and without our consent."

Six Portuguese young people have filed a legal complaint at the European Court of Human Rights  (ECHR) in Strasbourg, France, accusing 33 countries of violating their right to a secure future by failing to take action to mitigate the climate crisis. The youths aged 12 through 21, represented by the Global Legal Action Network (GLAN), are targetting countries whose policies on carbon emission reduction they say are too weak to meet the 1.5 degrees Celsius goal of the Paris Agreement, citing the country ratings of the Climate Action Tracker. Named in the suit are the 27 European Union member states, as well as the United Kingdom, Switzerland, Norway, Russia, Turkey and Ukraine.

The Global Mayors COVID-19 Recovery Task Force, representing cities on every continent, has announced a proposal for a post-pandemic "new normal" that will de-emphasize cars and carve out more room on the streets for bicyclists. The C40 Mayors Agenda for a Green and Just Recovery, issued July 15, seeks to create conditions that will proactively prepare cities for future pandemics, while addressing systemic injustices and keeping global warming below the 1.5°C goal of the Paris Agreement. The Agenda calls for substantial investments in affordable housing and public transportation, the permanent banning of cars from many thoroughfares, an end to public investment in and subsidies for fossil fuels, and an embrace of the "15-Minute City" paradigm now being pioneered by Paris.

The Ninth Circuit Court of Appeals on July 9 issued a ruling in favor of the US government, allowing oil drilling to proceed in the National Petroleum Reserve-Alaska (NPRA). The court rejected a claim by environmental groups that a 2012 impact statement prepared for earlier drilling within the NPRA was inadequate to cover new planned operations by oil companies elsewhere in the reserve, a critical caribou habitat.

The Supreme Court of Canada dismissed an appeal by the Squamish and Tsleil-Waututh First Nations in British Columbia, ending their years-long battle against the construction of the Trans-Mountain Pipeline. The pipeline is a controversial project to carry crude oil between Alberta and British Columbia's coast. The First Nations filed their appeal after a February decision by the Canadian Federal Court of Appeals that upheld the pipeline's legality. "The consultation process initiated by Canada invited the participation of 129 indigenous groups impacted by the project," stated that ruling, "and more than 120 either support or do not oppose it." The Squamish and Tsleil-Waututh contested this. In a 2018 appeal, the Tsleil-Waututh nation asserted sovereignty over the land, and their "freestanding stewardship, harvesting and cultural rights in this area." Both nations further claimed that the pipeline's construction would obstruct access to water, game and agricultural resources.

Leaders from the UN Convention on Biological Diversity, the World Health Organization and the World Wide Fund for Nature joined to issue a stark warning that pandemics such as COVID-19 are a direct result of the destruction of nature caused by human activity. In an op-ed published by The Guardian June 17, top figures from each organization state that the destruction of forests and other habitats for wildlife, coupled with trafficking in wildlife, is causing a growing number of animal diseases to migrate to human hosts. In their call to action ahead of the UN Biodiversity Summit to be held in New York in September, the three senior representatives cite examples from prior incidents of environmental destruction that triggered new virus outbreaks in humans.

One percent of the world's population has been forced to flee their homes due to war, conflict and persecution to seek safety either somewhere within their country or in another country, according to the latest Global Trends report released June 18 by UNHCR, the UN Refugee Agency. As more people became displaced than at any time since UNHCR began issuing its annual study, fewer were able to return home—or even build sustainable lives in another country. "We are witnessing a changed reality in that forced displacement nowadays is not only vastly more widespread but is simply no longer a short-term and temporary phenomenon," said UN High Commissioner for Refugees Filippo Grandi.
