We analyze current approaches to carbon accounting for removed carbon sold on carbon markets, focusing on carbon crediting under the framing of a remaining carbon budget, the issue of durability, and approaches to accounting methodologies.

We analyze current approaches to carbon accounting for removed carbon sold on carbon markets, focusing on carbon crediting under the framing of a remaining carbon budget, the issue of durability, and approaches to accounting methodologies. We explore the topic of mixing carbon with other problems in developing carbon accounting methodologies and highlight the open policy questions. We conclude with a suggested framework for accounting for carbon removal accounting that simplifies climate action and enables a world with negative carbon emissions.

This document details a conceptual Framework for the Certification of Carbon Sequestration (FCCS). It is based on a system designed to support negative emissions. It provides the minimum requirements for the development of carbon sequestration standards and certificates of carbon sequestration. It allows the certification of standards so that they in turn produce certification of removed carbon that authenticates durability and verifiability. The framework (i) identifies an organizational structure for the certification system, (ii) clarifies the responsibility of participating entities, (iii) provides certificate designs and usages, (iv) details the requirements to develop measurement protocols, (v) provides mechanisms to support a long-term industry, and (vi) outlines a vision towards durable storage.

Carbon Dioxide Removal (CDR) is essential to meet the Paris Agreement’s commitment to stay below a 1.5 degrees Celsius average temperature increase. To provide critical foundational support to the development, deployment, and scaling of CDR, certification of carbon removal is needed. The international community is developing rules for the functioning of carbon markets. To support that process, we explored open questions on four key themes in the development of standards and certification of carbon removal through an international multi-stakeholder consultation process hosted by the Global Carbon Removal Partnership, Arizona State University, and Conservation International. Categories of stakeholders included standard developing organizations, non-governmental organizations, governments, and academics. Discussions covered 1. the treatment of emission reduction, avoidance,and removal in certification, 2. the role of additionality in carbon removal, 3. the choice of certification instrument for carbon removal, and 4. the treatment of durability in certification. They revealed fundamental differences in viewpoints on how certification should work. We highlight areas of further exploration, concluding that providing transparency on assumptions made at the certification level will be crucial to progress and, eventually, the acceptance and success of carbon removal as a climate solution.

Topsy is an online analytical tool that evaluates millions of archived and real-time tweets based on their relevancy to a specific criterion. This report studies what Topsy considers relevant, how to create a relevant tweet, the accuracy of Topsy’s relevancy score and whether Topsy is an acceptable tool for use in gauging class participation. After thorough investigation, Topsy was determined to be a great analytical tool for monitoring Twitter participation, yet lacks the fundamental ability to distinguish between tweets relevant to coursework and tweets relevant to everything else.

Access to reliable electricity is at least a co-requisite to sufficient human development. In many developing countries, the percentages of the rural population that have electricity access are often below 5%. Specifically in Uganda, only about 2% of the rural population is currently served by the electric grid. To create effective policy and implementation programs, this paper examines the current challenges and implications of the current energy sector of Uganda. Ostrom’s Social-Ecological Systems framework is employed to organize the driving forces, interactions, and key players of the current system, including recent rural electrification programs that have resulted in some success. However, the implications of the current system include multiple barriers to widespread rural electrification, including high costs and little revenue. The push for solar photovoltaic systems in Uganda also has many shortcomings to improving development within the country. I end by discussing an alternative approach to rural electrification called the Empower Ugandans to Power Uganda Project that offers a locally driven effort to electrification and development.
