Carbon Dioxide Removal Leadership Act of 2024

"...Further, the government can and should require contractors to responsibly use those federal dollarsto deliver demonstrable results across a range of national priorities in addition to climate, such as equitable economic development and high-road labor practices. Federal CDR procurement should pair with policies that ensure its long-term efficacy, manage and mitigate any negative impacts, and maximize the benefits of resulting economic opportunity for underserved and over-polluted communities,and communities negatively impacted by the clean energy transition. Requirements and prioritization aroundequity, environmental integrity and responsible growth, like those in the Federal Carbon Dioxide Removal Leadership Act, are one tool for ensuring CDR contributes to an equitable net-zero transition and could help set precedents for the industry more broadly..."

7 Things to Know About Carbon Capture, Utilization and Sequestration

"...No, CCUS is not the same as carbon removal. Carbon dioxide removal(or just carbon removal) removes CO2 that is already in the atmosphere. Carbon removal includesa range of approachesfrom familiar things like tree restoration, to newer technological approaches likedirect air captureandcarbon mineralization..."

Lessons From Californias Carbon Dioxide Removal Policies

"...TheCalifornia Climate Crisis Act, or AB 1279, was signed into law in September of 2022, and requires net-zero greenhouse gas emission by 2045 and net-negative emissions thereafter. It mandates at least 85% emissions reductions from 1990 levels by 2045, ensuring that carbon dioxide removal does not play an excessive role in meetingnet zero..."

Recommendations for Governing Carbon Removal in Long-term Climate Planning

"...These governance gaps are also particularly relevant to the upcoming UN Conference on Climate Change (COP28), which will be held in Dubai in late 2023. Carbon removal along with carbon capture at emissions sources isexpected to be an area of focusgiven the hosts position as a small, oil producing country. Critical questions around carbon removals role in relation to emissions reduction and fossil fuel use are likely to be brought to the fore since the promise of carbon removal has been used by someto justify continued fossil fuel production..."

Canada must speed decarbonizing ports to slash rising shipping emissions

"...Upwards of 80 per cent of world trade is transported by ships burning fossil fuels that churn out three per cent of the planet’s greenhouse gas emissions. “And those of global emissions are set to go to 13 per cent by 2050,” Dancey said. What people are reading Wildfire smoke proof young people must take action By Alex Neufeldt | Opinion | June 19th 2023 International ships burning fossil fuel produce 1 billion tonnes of CO2 each year..."

4 Things to Know About New Developments in Carbon Dioxide Removal

"...Biomass-based CDR: Instead of combusting biomass and capturing the emissions (as is done with bioenergy with carbon capture and storage, or BECCS), there is growing interest in using biomass organic material from plants for direct carbon removal. One iteration of this fromCharm Industrialinvolves converting biomass left over from growing crops into a carbon rich bio-oil and injecting that into the ground where that carbon is sequestered. Another approach, developed byKodama Systems, involves improving forest management practices, including forest thinning to reduce wildfires, combined with burial of residual wood for carbon removal..."

How to Refine Californias 2022 Scoping Plan for Achieving Climate Neutrality

"...The Scoping Plan assumed a ban on new fossil gas power plants, resulting in the selection of hydrogen-burning turbines for electricity reliability needs. This should be reconsidered given the risk of higher NOx emissions from hydrogen turbines. The Scoping Plan also assumed that remaining fossil gas power plants would be retrofitted with carbon capture and sequestration (CCS) just before the 2045 deadline to reach net-zero emissions..."

What the heck is carbon capture? The pollution-cutting technology thats got Canada investing billions

"...How does carbon capture work?One of the three most common types of carbon capture technology removes CO2 after fossil fuels are burned and is called post-combustion carbon capture. This technology can be fitted onto existing power plants and many industrial facilities. What people are reading Justin Trudeau can’t ignore Quebec’s Islamophobia problem any longer By Max Fawcett | Opinion, Politics | January 31st 2023 Post-combustion carbon capture works by taking CO2-laden exhaust gas from industrial processes and isolating the CO2, typically using a chemical compound that binds to CO2 molecules..."

Ocean-based Carbon Dioxide Removal: 6 Key Questions, Answered

"...At the same time, what the ocean has done to buffer the impacts of climate change has come at a high cost. Absorbing excess CO2 and heat is causing ocean warming, acidification and oxygen loss; changing currents and nutrient cycling; and imperiling plants and animals essential to marine ecosystems. These changes are compromising the oceans ability to provide food, support livelihoods and insulate us from the worst effects of climate change..."
