Investing for climate action: The role of capital markets in enabling a low-carbon transition
(University of Waterloo, 2022-09-26)Economies around the world face a stark choice – to bolster fossil fuel production and face climate catastrophe or to keep fossil fuels in the ground and face trillions in potential asset stranding. Capital markets, as ... -
An Investment Decision under the Clean Development Mechanism: A Real Options Approach
(University of Waterloo, 2009-09-08)One of the main challenges that investors in the Clean Development Mechanism (CDM) project face is the management of the volatility of the price of Certified Emission Reduction (CERs). Large scale CDM projects require a ... -
Investment Planning Models and Optimal Incentive Design for System Planners and Investors to Integrate Renewables
(University of Waterloo, 2014-08-14)Emissions from fossil fuel based energy sources is a global concern with respect to environmental degradation. Thus, a diversification of energy sources in the supply mix of power systems to include renewable sources of ... -
Invisible Boundaries
(University of Waterloo, 2011-08-12)Within Buenos Aires there exists a boundary between the formal, planned developments of the middle class and the informal, organically-developed self-built housing of the poor. Villa 31, an informal settlement located near ... -
The Involvement of Business Improvement Areas in Tourism: An Exploratory Study of Ontario BIAs
(University of Waterloo, 2009-08-13)Local festivals and cultural events, signage and streetscape improvements, and regional marketing efforts indicate that tourism is present in some Business Improvement Areas (BIAs). However, the extent and form of this ... -
