Negative emissions: Scientists debate role of CO2 removal in tackling climate change

"...Of the novel approaches, he explained that biochar is the main player. This is followed by bioenergy with carbon capture and storage (BECCS), which is confined to essentially two plants in the US.  ..."

What Economics Does or Doesnt Tell Us About the Climate Consequences of Using Wood

"...Timothy Searchinger is a Senior Research Scholar at Princeton University and Technical Director for Agriculture, Forestry and Ecosystems at WRI. This article was written in collaboration with Steve Berry, David Swenson Professor of Economics at Yale University and Faculty Director at the Tobin Center for Economic Policy.  To reduce global carbon emissions, should people harvest and use more wood or less? This question underlies the merits of policies that encourage power plants and heating facilities to burn more wood pellets and builders to construct more tall wood buildings..."

4 Growing Threats to Europes Forests: Logging, Bioenergy, Wildfires and Pests

"...Europes forests face increasing pressures. Impacts include fewer tall forests, climate change-induced wildfires, insect outbreaks, and, most recently, increased wood harvesting to meet additional demand for home-grown biomass in response to the Ukraine war and changing energy demands. Against this backdrop, the EUs new Nature Restoration Law will introduce critical safeguards to protect remaining old-growth forests, set aside additional forests for restoration, and improve the biodiversity of forests managed for wood production..."

EPA approves year-round sales of higher ethanol blend in 8 Midwest states

"...The biofuels industry and politicians of both parties have portrayed ethanol as a product that helps farmers, reduces prices at the pump and lessens greenhouse gas releases because the fuel burns more cleanly than straight gasoline. However, environmentalists and others have said increased ethanol production can increase carbon releases because it results in more corn production, leading to increased use of fertilizer and greater releases of nitrate. Synthetic and natural fertilizers also are a leading source of water pollution..."

Forestry is key to growing a resilient bioeconomy in B.C.

"...More deeply integrating the bioeconomy with forestry is a key strategy for conservation, fire resilience and sustainable land management. By carefully managing forests, extracting value from every part of a tree, using wood residues and waste for value-added manufacturing and energy, while replanting trees, it's possible for B. C..."

Guest post: Heavy use of CO2 removal would trigger high sustainability risks

"...Yet the large-scale deployment of land-based CDR could come with major challenges. These include significant ecological and societal risks particularly to biodiversity loss, food security, freshwater use and human rights, among others which have not been comprehensively assessed..."

What is biomass? The latest fuel source to get clean tech tax credits

"...In a response to the BBC, Drax maintains they only use sawdust and other waste wood that the lumber industry does not want. Natural Resources Canada says forest biomass is a renewable source of feedstock for energy production” as long as it comes from a sustainably managed forest and regrows over time. Still, Roberston says there are concerns..."

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..."

Latin America

"...Beyond tackling CO2 emissions, major producers in the region can reduce methane emissions from oil and gas operations by nearly 80 per cent at low cost, and around 40 per cent with no net costs, supporting the Global Methane Pledge that most countries have signed. Based on announced pledges, emissions from land use and agriculture, which account for half of economy-wide greenhouse gas emissions in the region today, are cut by the end of the decade and reach net zero. About 85 per cent of forests in the region are in countries that are part of the Glasgow Pledge, which aims to stop deforestation by 2030..."

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..."

Q&A: What does the UKs new biomass strategy mean for net-zero?

"...Biomass defined within the strategy as any material of biological origin contributed 8. 6% of the UKs energy supply in 2022. It is currently used predominantly for electricity generation, biofuel in vehicles and domestic heating..."
