The Carbon Cycle:

  • The Global Carbon Project’s scientific goal is to develop a complete picture of the global carbon cycle [click here]

Cutting emissions:

Ways of extracting greenhouse gases from the atmosphere going forward must go with deeps cuts greenhouse gas emissions right now:

  • Help get emissions reduction activities to a gigatonne scale with the Carbon War Room, who’ve recently teamed up with the Rocky Mountain Institute  [click here]
  • In particular, if you’re interested in how better ways of cooling buildings can help cool the planet, check out the Global Cooling Prize in partnership with Conservation X Labs, Cept University and Alliance for an Energy Efficient Economy, and supported by the Government of India and Mission Innovation [click here]

Air Miners:

  • Air Miners is the index of companies and projects mining carbon from the air. They recently did an early run of planters made with CO2 extracted from the atmosphere: making some small, early, concrete steps towards climate-positive materials [click here]

Biodiversity for a Livable Climate:

  • Biodiversity for a Livable Climate is a grassroots movement whose goal is to contribute to planetary regeneration through research, education, collaboration and action to restore essential global biodiversity.  [click here]

Carbon 180:

  • Carbon180 is a new breed of climate-focused NGO on a mission to fundamentally rethink carbon. They partner with policymakers, scientists and businesses around the globe to develop policy, promote research, and advance solutions that transform carbon from a liability to an asset (a pollutant to a resource) and foster a prosperous, carbon-conscious economy that removes more from the atmosphere than we emit.

Carbon A List:

  • Carbon A List is on a mission accelerate the flow of money and awareness to novel innovations that can close the carbon cycle. [click here]

Intergovernmental Panel on Climate Change: Global Warming of 1.5 °C

  •  The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UN Environment) and the World Meteorological Organization (WMO) in 1988 to provide policymakers
    with regular scientific assessments concerning climate change, its implications and potential future
    risks, as well as to put forward adaptation and mitigation strategies. The IPCC has 195 member states.
  • Limiting global warming to 1.5ºC would require rapid, far reaching and unprecedented changes in all aspects of society, the IPCC said in a new assessment, the full title of which is: ‘Global Warming of 1.5°C, an IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty’.
  • With clear benefits to people and natural ecosystems, limiting global warming to 1.5ºC compared to 2ºC could go hand in hand with ensuring a more sustainable and equitable society [click here].

National Academies of Sciences, Engineering, and Medicine: Negative Emissions Technologies and Reliable Sequestration: A Research Agenda

  • Back in 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed a range of carbon removal approaches.That report acknowledged the relative paucity of research on so-called ‘Negative Emissions Technologies’ (NETs); it also recommended development of a research agenda that covers all aspects of carbon removal: from fundamental science to full-scale deployment.
  • To address this need, in 2018 a new report: Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assessed the benefits, risks, and “sustainable scale potential” for a range of different carbon removal techniques.
  • The report also defines the essential components of a research and development program, including estimated costs, and potential impact. [click here]

The Nature Conservancy: Natural Climate Solutions

  • Climate change is a global problem, and it requires solutions on a global scale. According to The Nature Conservancy, one of those is hiding in plain sight: the world’s lands provide an untapped opportunity – proven ways of both storing carbon and reducing carbon emissions in the world’s forests, grasslands and wetlands: ‘natural’ climate solutions.

Project Drawdown: The Most Comphrehensive Plan Ever Proposed to Reverse Global Warming

  • Project DRAWDOWN is a nonprofit organization. Made up of a coalition of scholars, scientists, entrepreneurs, and advocates from across the globe, Drawdown has produced the most comprehensive plan ever proposed to reverse global warming. [click here]

The Royal Society: Greenhouse Gas Removal

  • The Royal Society, in partnership with the Royal Academy of Engineering, has produced a report and associated summary to outline methods of greenhouse gas removal and how other influences like legislation, the environment, economics or social factors will affect their deployment.
  • The report also considers how they might plausibly be used in the UK and globally to meet climate goals. [click here]
