The document advocates for the transition from incandescent and mercury vapour lighting to compact fluorescent lamps (CFLs), LEDs, and efficient fluorescent tubes in South African urban areas. It highlights that lighting accounts for approximately 12% of electricity use in the residential and commercial sectors, and replacing traditional bulbs with CFLs can reduce this by up to 75%. Using Cape Town as a model, the guide estimates that achieving penetration targets could save 8 million MWh of electricity and 7.5 million tonnes of CO2 by 2024. It identifies barriers such as high initial costs for low-income households and municipal reluctance to reduce electricity sales, while suggesting implementation strategies through procurement policy changes and Eskom's demand side management (DSM) subsidies. Case studies from Ekurhuleni and international examples from Australia, the USA, and India illustrate the economic and environmental viability of these interventions.

The document explains the use of decomposition reports in LEAP to analyze trends in scenarios using the IPAT and Kaya identity frameworks. It details the configuration of these reports, the ability to decompose various indicators such as GHG emissions or air pollutants, and the available visualization options, including waterfall charts and time-series bar charts.

The document describes the functionality of the LEAP software's Fuels screen, which allows users to view and edit a database of fuels. It details how to manage fuel properties such as net energy content (lower heating values), chemical compositions (carbon, sulfur, and nitrogen), and classifications (fossil, renewable, biomass, secondary fuel, and electricity). The guide explains how to customize fuel names for local languages, assign fuels to groupings for aggregated reporting, and specify land-type disaggregation for biomass and renewable resources. It also notes that the default database is based on IEA and UN sources, though users can modify data to reflect specific regional conditions, particularly for coal and wood.

The document explains the functionality of the LEAP Scenario Manager, focusing on the hierarchical structure of expression inheritance to minimize data entry. It details how to edit scenario properties, such as Global Warming Potential (GWP) values and Marginal Abatement Cost Curve (MACC) report inclusion, and describes the tools available for adding, deleting, and duplicating scenarios.

The document provides technical instructions for associating environmental loadings with energy devices and fuels in LEAP. It details the use of the Technology and Environmental Database (TED) for default emission factors, the ability to manually enter or override factors using mathematical formulae, and the handling of units and dynamic emission factors for future scenarios.

The document describes Marginal Abatement Cost Curves (MACCs) as tools for assessing the cost and abatement potential of mitigation options. It details three calculation approaches—Partial, Retrospective, and Integrated Systems—and specifies that LEAP supports the Partial and Retrospective methods. The guide provides technical instructions for configuring MACC reports in LEAP, including scenario selection, variable definition for social costs and global warming potential, and the process for refreshing and exporting results.

The document provides a comprehensive checklist of data requirements for users of the LEAP software, emphasizing that requirements vary based on whether a user chooses an aggregate top-down or disaggregated bottom-up approach. It details necessary inputs across demographic, macroeconomic, and energy sectors, including demand forecasting metrics and supply-side technical data. The guide notes that national energy balances are the most critical data source and suggests supplementing missing domestic data with international sources or estimates.

The document outlines the process for non-Annex I Parties to assess and report greenhouse gas (GHG) mitigation measures. It defines mitigation as interventions that reduce emission sources or enhance sinks and provides a structured approach to creating baseline and mitigation scenarios. The guide reviews sectoral options across energy, transport, buildings, industry, agriculture, forestry, and waste, while identifying technical, economic, and institutional barriers. It further evaluates bottom-up modeling tools such as LEAP, MARKAL/TIMES, and ENPEP to help countries quantify mitigation potentials and report results using standardized formats like 'jaws' charts.

The document outlines a 'funnel' process for wind resource assessment, moving from general wind maps to site-specific measurements. It emphasizes that wind energy production is approximately proportional to the square of wind speed, meaning small estimation errors can lead to significant financial losses. The guide details the use of wind power classes, the impact of wind shear on tower height selection, and the importance of analyzing year-to-year wind variability to satisfy lender requirements. It also provides specific siting advice regarding wind roses, turbine wake effects, and the use of set-backs or easements to protect wind access.

The document serves as a guide for school districts and fleet operators to calculate the total cost of ownership (TCO) for electric school buses (ESBs) versus diesel buses. It addresses the lack of consistent, centralized public data by providing recommended default specifications for parameters including purchase costs, maintenance, fuel economies, and charger installation. The guide also notes the upcoming expiration of the 45W and 30C tax credits due to a July 2025 budget reconciliation bill.

The document details the requirements for Parties to the Paris Agreement regarding the communication and accounting of their NDCs. It outlines the seven elements of CTU guidance adopted in 2018, the mandatory accounting standards based on IPCC methodologies, and the integration of these elements into the broader Paris Agreement cycle, including the Enhanced Transparency Framework and the Global Stocktake.

The document details the 'who, what, when, and where' of the Paris Agreement's enhanced transparency framework, focusing on Biennial Transparency Reports (BTRs), technical expert reviews, and the facilitative, multilateral consideration of progress. It outlines specific reporting obligations for different Party types, the timeline for BTR submissions starting December 31, 2024, and the self-determined flexibility available to developing countries regarding GHG inventory data and review formats. Additionally, it maps the framework's linkages to NDCs, the Global Stocktake, and compliance mechanisms.

The document argues that reducing natural gas leakage to 1% or less of total production is a cost-effective and achievable benchmark that ensures natural gas remains less climate-intensive than coal, diesel, and gasoline. It emphasizes that the rapid increase in US natural gas production, driven by hydraulic fracturing and horizontal drilling, necessitates state and federal regulation across the supply chain to address climate and air quality concerns. The paper offers practical solutions, case studies, and model rules to help state officials structure policies and comply with Clean Air Act standards.

The document outlines a 'build back safer and greener' framework for Nepal, focusing on minimizing environmental damage during post-disaster recovery. It provides sector-specific guidance on settlements, building construction, waste management, energy, infrastructure, WASH, agriculture, and education. Key strategies include the use of soil bioengineering for landslide stabilization, integrated settlement planning, and the promotion of renewable energy to reduce pressure on forests. The guide emphasizes cross-cutting issues such as gender equality, social inclusion (GESI), and climate change adaptation to enhance long-term community resilience.

The report provides a comprehensive framework for implementing electronic monitoring (EM) in industrial tuna fisheries, focusing on the role of Regional Fisheries Management Organizations (RFMOs). It outlines a five-phase implementation process—assessment, program design, pre-implementation, initial implementation, and continuous improvement—and evaluates three governance scenarios: centralized, decentralized/harmonized, and various service provider interaction models. The document emphasizes the transition from technical to performance-based standards to accommodate rapid technological advances in AI and machine learning. It identifies significant gaps in financial transparency and cost-recovery research and recommends the creation of a global EM program database to facilitate data-driven decision-making.
