Talk by Christian Holz, “Fairly Sharing 1.5 …”
February 6 @ 2:30 pm - 4:00 pm
ABSTRACT: Climate science can inform us (albeit with uncertainty) what overall global level of greenhouse gas emissions reduction would be required to limit global warming to a certain temperature level, say the 1.5°C featured in the recent report of the IPCC . However, the question of how this is global mitigation effort is to be shared among the countries and, ultimately, the people of this planet, is a question of ethics, politics, and justice. The Paris Agreement’s  bottom-up approach combines with the severity of the 1.5°C challenge to make the equity and fair shares debate absolutely critical. This talk will present work ,  that aims to shed light on this question, starting from the universally accepted ethical principles of the UN climate convention to build a normative framework that allows identifying “fair shares” of the global effort for countries or other entities. The results have fundamentally important implications for the structure of the world’s response to the climate challenge. Further, these “fair shares” can then be contrasted to the effort that countries pledged to undertake in the context of the UN climate negotiations.
Dr. Christian Holz is a post-doctoral research fellow at the Department of Geography and Environmental Studies at Carleton and the Senior Research Associate of the Climate Equity Reference Project. An active and long-standing participant in the UN climate negotiations, he aims to combine rigorous scholarship and effective advocacy to address the global climate crisis. His work includes research and advocacy in the context of international climate change politics, especially the multilateral UN climate regime and focusses on the role of equity as an enabler of ambitious climate action while protecting the right of the world’s poor to a better life. He is a co-author of a series of annual equity and ambition assessments of countries’ climate pledges, whose first installment – Fair Shares: A Civil Society Equity Review of INDCs – was described as the single most influential climate justice intervention at the 2015 UN Paris Climate Summit (and even made it into the speeches of some Heads of States there). Christian is also a past Executive Director of Climate Action Network Canada (2012-2014) and currently serves on the boards of Climate Action Network International and Climate Action Network Canada.
