Developing a Portfolio of Negative Emissions Technologies

open access: yesJournal of Student Research, 2023
The only way we can achieve the IPCC’s goal of limiting warming to 1.5ºC is through a massive expansion of negative emissions technologies (NETs), chiefly carbon dioxide removal (CDR). To date, point-source carbon capture has been the most widely recognized and deployed form of CDR, but it is limited in its efficacy in achieving negative emissions ...

High photoreactivity of chromophoric dissolved organic matter derived from Ulva prolifera and Sargassum

open access: yesFrontiers in Marine Science
The epipelagic macroalgae of Ulva prolifera and Sargassum are the primary contributors to widespread seaweed tides globally. Both ocean plants release large amounts of chromophoric dissolved organic matter (CDOM) into the surrounding seawater.

Technological Demonstration and Life Cycle Assessment of a Negative Emission Value Chain in the Swiss Concrete Sector

open access: yesFrontiers in Climate, 2021
Switzerland, such as most of the other countries which are part of the Paris agreement, decided to reduce GHG emissions to zero by 2050. The ambition of net-zero GHG emission across all industrial sectors can only be achieved by rapid decarbonization and

Incentivising and Accounting for Negative Emission Technologies

open access: yesEnergy Procedia, 2014
AbstractUnlike conventional greenhouse gas abatement technologies, which generally only eliminate or reduce emissions towards zero, negative emission technologies are able to remove CO2 from the atmosphere. One such technology is the application of carbon capture and storage (CCS) to biogenic CO2 sources (bio-CCS), such as those arising from biomass ...

Biochar mitigation potential in Norway estimated by IPCC Tier 1 and Tier 2 methods

open access: yesCarbon Management
Biochar is a recalcitrant carbon-rich solid produced by pyrolysis of organic residues, and its application to soil is considered a promising approach to mitigate climate change, as biochar resists decomposition to readily contributes to soil carbon (C ...

Impact of population growth on Carbon Dioxide (CO2) emission: empirical evidence from Nigeria

open access: yesJurnal Perspektif Pembiayaan dan Pembangunan Daerah, 2019
This paper seeks to examine the impact of population growth on carbon dioxide emission in Nigeria. Time series data from 1975 to 2016 was adopted. Variables such as population, affluence and technology were used as independent variables which were ...

The Impacts of Freight Trade on Carbon Emission Efficiency: Evidence from the Countries along the “Belt and Road”

open access: yesComplexity, 2020
Extensive research has been carried out on the “Belt and Road” initiative, most of it focusing on geographical economy and international trade. However, there is a lack of research on the carbon emissions efficiency of the countries along the “Belt and ...
