This seminar will explore the options to significantly reduce system-wide carbon emissions. Specifically, carbon reduction options in the built environment, and throughout supply chains will be discussed.The first two speakers will focus on financing mechanisms to improve energy efficiency and reduce carbon emissions in buildings. Speakers three and four will focus on supply chain wide carbon emissions options. Speaker three will present tools for consumer goods manufacturers, and speaker four will discuss practices in China.

Speakers’ Abstracts

Andrew Joyner, “Financing Energy Efficient Retrofits in the Built Environment”

Buildings consume more than one-third of the world’s energy and, in cities, buildings can account for up to 80 percent of CO2 emissions. The built environment is therefore a critical part of the climate change problem – and solution. Most existing buildings were not designed to be energy efficient; but by retrofitting with modern technologies, a typical building can realize significant energy savings. However, building owners must make a large up-front capital investment to fund retrofit projects. Energy efficient retrofit financings stretch out the payments for a retrofit over the functional life of the green technology, creating cost neutrality for the borrower. Therefore retrofit finance represents a budget friendly way to empower property owners to invest in a clean energy future.

Based on the experiences of The Clinton Foundation’s Energy Efficient Retrofit Team, Andrew will discuss the financing models that have met resistance, highlight the key market barriers, and shed light on the emerging models that are currently gaining momentum in the US and the UK.

Jenny Ya He, “Financing Energy-Efficient Lighting in Hotels”

The research seeks to understand the barriers to energy efficiency retrofit in commercial buildings through investigating the financing of energy efficient lighting in hotels. Hotel establishments are used as an exemplar of commercial sector buildings, which embed complex organisational structure and contractual relationships for ownership and management. Lighting technologies are representations of cost-effective energy efficient technologies; their strong economic case will expose the financial barriers and other factors hindering energy efficiency in the built environment. Financing mechanisms are financial packages, which overcome the financial, social and human behavioural underpinnings of energy efficiency retrofit. The research lies at the interface of the implementation of new technologies, energy efficiency finance and the organizational and operational context of commercial buildings. The study aims to reveal and to shed light on the processual and contextual intricacies of different financing mechanisms for energy efficiency.

Nancy Bocken, “Identification and Evaluation of Options to Reduce Supply Chain Wide Carbon Emissions Associated with Consumer Goods”

Consumer goods manufacturers aiming to reduce the environmental impact associated with their products are already pursuing incremental changes, but these have only small effects. One strategy to anticipate more stepwise reductions throughout the product life cycle, is to prepare a portfolio of innovations providing different levels of impact reduction in exchange for different levels of commitment. This research aims to develop two tools to support this strategy. The first tool aims to facilitate the generation of radical product and process ideas giving step change emissions reductions. The second tool aims to predict the environmental benefit of each innovative option against the difficulty of implementation. Initial trials of the tool set suggest that it facilitates rapid development and evaluation of eco-innovative options.

Jialun Hu, “Low Carbon Supply Chain: Some Practices in China”

When the world is calling for low carbon emission industry revolution, China, contributing second largest emissions just listed behind the U.S., is also paying great attention to reduce GHG through different kinds of technology and innovations. Having pressure from government policy, MNCs and domestic companies are both transforming not only the production process but also their supply chain, including product innovation, transportation and customer use after sales.This talk aims to give a glance at some of the recent decarbonization practices in electronic and automotive industry of China.
