Alto Mayo Protected Forest REDD Initiative, PeruCIFOR-ICRAF
To measure the success of REDD (Reducing Emissions from Deforestation and forest Degradation), it is crucial to first set baseline emissions from which the reduction can be measured in each project or region. In this presentation, Fabiano Godoy from Conservation International shared experiences with applying the VCS VM0015 model in the Alto Mayo protected forest of Peru in order to set baseline emissions.
Fabiano Godoy gave this presentation on 8 March 2012 at a workshop organised by CIFOR, ‘Measurement, Reporting and Verification in Latin American REDD+ Projects’, held in Petropolis, Brazil. Credible baseline setting and accurate and transparent Measurement, Reporting and Verification (MRV) of results are key conditions for successful REDD+ projects. The workshop aimed to explore important advances, challenges, pitfalls, and innovations in REDD+ methods — thereby moving towards overcoming barriers to meeting MRV requirements at REDD+ project sites in two of the Amazon’s most important REDD+ candidate countries, Peru and Brazil.

This document discusses potential strategies for reusing an old mill building in Fall River, Massachusetts in an environmentally sustainable way. It outlines three key ways the mill reuse project could reduce CO2 emissions: 1) Reducing travel through activity concentration on site, 2) Improving energy efficiency through the mill building's compact design, and 3) Avoiding emissions from new construction through building reuse. It argues that documenting these CO2 reductions could allow the project to receive carbon credits to help fund retrofitting the mill for low-carbon uses.
This document discusses a conference on beyond zero carbon housing held at the University of Nottingham. It begins by introducing the concept of a zero carbon hierarchy to help define zero carbon goals. It then covers topics discussed at the event including fabric energy efficiency standards, carbon compliance targets, understanding the impact of the 2011 budget changes, lessons from case studies on performance gaps between design and implementation, and monitoring in-use energy consumption.

Wood plays an important role in combating climate change by storing carbon extracted from the atmosphere during photosynthesis. About half the weight of wood is carbon. Wood construction requires less fossil fuels than other materials like concrete and stores carbon throughout the lifetime of wood products. Case studies show wooden buildings can have lower lifecycle carbon footprints than non-wood alternatives. A holistic, collaborative design process is important to ensure low carbon footprints by making informed material and system choices early in the design phase.

Biogas can be used as an alternative vehicle fuel and is produced through anaerobic digestion of organic waste. It has the potential to displace 10-15% of fossil natural gas use by 2025. Biogas is 50-80% methane and can be upgraded to renewable natural gas (RNG) by increasing methane levels. Common sources of biogas include landfills, animal manure, and wastewater treatment plants. In Wisconsin, Dane County and the City of Janesville produce biogas from their landfills and wastewater facilities respectively to fuel their vehicle fleets, saving on fuel costs.
The document discusses retrofitting homes and buildings to reduce carbon emissions. It outlines the services provided by Low Carbon Zones, including funding, feasibility studies, project management, and retrofitting existing homes and non-domestic buildings. It also discusses challenges to retrofitting such as risk aversion, high capital costs, limited supply chains, and resistance to change. The goal is to cut UK carbon emissions 80% by 2050 through innovative retrofit solutions and area-based projects.
Reducing Embodied Carbon in the built environment will play an increasingly important role in reducing overall carbon emissions over the next 20 years. For buildings, the focus has mostly been on reducing emissions by reducing the use of fossil fuels for operating energy. But we also need to reduce the carbon emissions embodied in the materials and resulting from the construction phase. As buildings become more efficient to operate, the embodied energy and emissions from materials and construction becomes an increasingly significant portion of total GHG emissions.

This document discusses the role of chemistry in addressing energy and climate change issues. It notes that 30% of energy is lost before reaching end users and 42% of non-transport energy is used to heat buildings, with a third of that lost through windows. Transportation accounts for 74% of UK oil usage and 25% of carbon emissions. The document argues that chemical science can provide energy that is secure, affordable, sustainable, and helps address climate change through solutions like improved efficiencies, renewable energy, carbon capture and storage, and new materials. A long term sustainable energy solution will likely involve solar power, biomass, hydrogen, and electricity and hydrogen storage supported by chemical advances.
Ferrock is a proposed substitute for traditional cement that could significantly reduce greenhouse gas emissions. It is composed partly of recycled steel dust and captures between 8-11% of its weight in CO2 as it cures. Tests show Ferrock has stronger compressive and flexural strength than Portland cement. Researchers are studying its potential to make structures like building columns more blast resistant, helping to save lives in disasters. Adopting Ferrock could help cement-producing countries like India and China move to a more sustainable future.
This document analyzes productivity growth, energy efficiency, and carbon emissions in India's cement industry from 1973-1993. It finds that after initial declines, the industry's total factor productivity increased 0.8% annually from 1983-1991 following deregulation. The industry became more energy and capital intensive over this period based on econometric analysis. While energy efficiency has improved, substantial potential remains to adopt best practices and reduce carbon emissions through new technologies. Adopting more efficient production methods could significantly reduce the industry's future energy use and emissions.
This document summarizes a report analyzing energy efficiency and carbon dioxide emissions reduction opportunities in the US cement industry. It examines the industry trends from 1970-1997, describes the cement production process, analyzes the industry's 1994 energy use and carbon emissions, identifies 30 energy efficiency technologies and measures for the industry, and estimates the technical and cost-effective potential for reduced energy use and carbon emissions through these measures. The key findings are an estimated 11% reduction potential in 1994 energy use and 5% reduction in carbon emissions from cost-effective efficiency measures.
The green benefits of cement and concrete are hidden due to the vast quantities consumed around the globe. Therefore, despite the low carbon footprint, cement and concrete are often given low marks for sustainability. The presentation attempts to set the record straight.

This document reviews the use of baggase ash and rubber tyre waste as replacements for natural aggregates in concrete. It discusses the large amounts of tyre and baggase ash waste generated globally each year and the environmental issues caused by improper disposal. The document outlines a study that used 0-25% baggase ash and 10% rubber tyre waste as replacements in M30 and M25 grade concrete. Tests on compressive strength, split tensile strength, and flexural strength showed that 15% baggase ash provided the best results, increasing concrete strength compared to the control mix. The study demonstrates that utilizing these wastes in concrete production can help address waste management issues while improving some concrete properties.
An Experimental Study on Strength of Concrete by Using Red Mud as Partial Rep...IRJET Journal
The document presents the results of an experimental study on using red mud as a partial replacement for cement in concrete. Red mud is a waste product generated during the Bayer process of refining bauxite into alumina. Four concrete mixes were tested with red mud replacing 0%, 5%, 10%, and 15% of the cement. Compressive strength was tested on concrete cubes at 7 and 28 days. The results showed that compressive strength increased when red mud replacement was increased from 0% to 10%, but decreased at 15% replacement. It was concluded that red mud can effectively replace up to 10% of cement while still meeting strength standards, providing an environmentally friendly way to utilize this industrial waste product.

IRJET- Partial Replacement of Cement Clinker with Limestone and Low Quality C...IRJET Journal
This document discusses a study on partially replacing cement clinker with limestone and low-quality calcined clay in concrete. The study aims to reduce the carbon dioxide emissions from cement production. Specifically, it examines a ternary blend called LC3 consisting of calcined clay, limestone, and cement clinkers. The methodology involved testing the properties of materials, determining the optimum dosage of calcined clay, selecting potential mixes, designing M30 concrete mixes, and evaluating the compressive strengths of concretes made with LC3, ordinary Portland cement, and pozzolanic cement at various ages. The results indicate that LC3 has potential to reduce the clinker content and associated CO2 emissions from cement.
An Investigation Into The Use Of Waste Polyethylene In Bituminous Paving Mixt...IRJET Journal
This document discusses an investigation into using waste polyethylene in bituminous paving mixtures. The study aimed to determine the effects of adding shredded polyethylene obtained from water sachets to asphalt. Polyethylene was added as a binder modifier by heating and mixing it with bitumen. Six mixtures with polyethylene contents ranging from 2.5-15% by weight of bitumen were tested. The specific gravity, tensile strength, and softening point of polyethylene were determined. Marshall samples were prepared and tested to evaluate the properties of mixtures containing polyethylene modified bitumen. The results showed that adding polyethylene can improve the performance characteristics of asphalt mixtures by increasing the softening point and strength.
UTILIZATION OF BLACK COTTON SOIL IN THE MANUFACTURE OF BRICKSIRJET Journal
This document discusses utilizing black cotton soil to manufacture bricks. Black cotton soil is a type of clay soil with low bearing capacity and high shrinkage. Tests were conducted on black cotton soil samples to determine properties like specific gravity, liquid limit, plastic limit, and compaction. Bricks were manufactured using a mixture of black cotton soil, rice husk powder, coal powder, and lime powder. The bricks were molded, dried, and fired. Compression tests found that bricks made from black cotton soil had a higher strength of 5.68 N/mm2 compared to 4.25 N/mm2 for standard red soil bricks. Therefore, black cotton soil is a suitable and potentially stronger material for brick manufacturing where it is locally available
STUDY TO PERFORMANCE OF BITUMEN MIX USING E-WASTE FOR FLEXIBLE PAVEMENTIRJET Journal
This study investigates the use of e-waste materials in bitumen mixes for flexible pavement construction. E-waste production is increasing rapidly with urbanization and technological growth. Using e-waste in pavement could provide environmental benefits by reducing disposal in landfills. The study aims to analyze the properties of bitumen mixes containing e-waste and compare them to traditional bitumen mixes. Laboratory tests will examine the characteristics and performance of e-waste modified bituminous mixes, including their load bearing capacity. The goal is to determine if e-waste can be used cost-effectively in pavement construction while maintaining adequate strength and durability.
