Saskatoon Author’s New Book on Climate Change Receives Strong Endorsement from Highly-Respected Climate Advocacy Organization. (April 23, 2018)


A recent book on climate change and climate policy written by a Saskatoon author and scientist has received a strong endorsement from the Executive Director of Citizens’ Climate Lobby, one of the most respected and influential grass roots organization advocating for climate change solutions. The Price of Carbon was researched and written by over a two and a half year period by David Maenz, a Saskatoon based scientist and co-founder of MCN BioProducts. The author’s stated intention in writing the book was to provide an objective, factual, science-based narrative on the subjects of man-made climate change and the pathways of mitigation and adaptation required to minimize or avoid a future of serious and costly climate change damage.

There are currently 92,000 members of Citizens’ Climate Lobby working within 479 active chapters located across the globe. CCL’s advisory board is comprised of notable climate scientists, James Hansen, Katharine Hayhoe and Daniel Kammen along with former US Secretary of State George P. Shultz, former US Representative Bob Inglis and former US Secretary of Energy Steven Chu. Among the goals of CCL is to build political support across party lines for the adoption of fair, effective and sustainable climate change solutions.

Citizens’ Climate Lobby released a statement of endorsement for the Price of Carbon that includes a recognition of the efforts of Canada to implement carbon pricing mechanisms as part of provincial and national climate action plans.

“Since the Paris Agreement in 2015, Canada has emerged on the world stage as a leader in carbon pricing. The Price of Carbon is a timely book full of important information for those seeking to understand the urgency of the climate crisis and the powerful solution of pricing carbon. Thank you David Maenz. The world needs carbon pricing. The world needs more Canada.”
– Mark Reynolds, Executive Director Citizens’ Climate Lobby

In responding to the statement from CCL, Dr. Maenz elaborated on the approach taken by CCL in lobbying governments and promoting awareness. “This endorsement comes from perhaps the most respected and effective lobby group working to promote the implementation of effective climate action plans. CCL has no right or left wing political bias and has no bias for or against specific technologies or pathways to achieve the objectives of the Paris Agreement. This organization is highly focused on promoting carbon pricing as a proven, cost-effective, market-driven mechanism to drive down emissions and change industrial and consumer practices. The Price of Carbon was written with a similar set of core values and I am honored and grateful that the book has received this endorsement. As pointed out by Mr. Reynolds, Canada has made considerable progress in implementing effective climate action plans at the provincial and national level. This process must continue to advance and there is no latitude for a pull back on carbon pricing and other climate legislation if Canada is to meet the year 2030 obligations as defined under the Paris Agreement.”

About the Author:
David Maenz received his Ph.D. from the University of Saskatchewan and held several academic positions prior co-founding MCN BioProducts in 2001. Dr. Maenz is the inventor or co-inventor of 7 patents and is the author of 33 scientific papers and 2 book chapters. Dr. Maenz has retired from business interests and lives in Saskatoon.
The Price of Carbon was written by a scientist with a broad interest in the cause and effects of climate change and in the pathways of mitigation and adaptation to avoid or limit future damage from excess emissions. The intent of the author was to distill the findings and conclusions of expert groups such as the Intergovernmental Panel on Climate Change and the International Energy Agency, into a narrative for a wider audience. The book was written from a global perspective and avoids over simplification of what is perhaps the most important issue of our time.

Do you want to understand Global Warming without the political hype? Dr. David Maenz has written and important book for 2018 explaining the science of global warming, it’s impacts and viable solutions. The Price of Carbon is a great read. You don’t have to be a climate scientist to understand his clear explanations and comprehensible charts.


The book includes a brief history of the earth, where we are today, future climate scenarios and how to fix the problems. It also covers the Paris accord without the political furor.

Carbon Pricing Works and Failure to Implement a Carbon Tax is a Form of Climate Change Denial (Published April 16, 2018, Regina Leader-Post)

The Saskatchewan Party remains stridently opposed to carbon pricing. The government defends this position by stating that BC’s carbon tax is ineffectual. However, a recent review from the Fletcher School of Law and Diplomacy at Tufts University concluded that BC’s carbon tax “reduced emissions between 5%-15%, absent of additional policy, when compared to a business-as-usual scenario”. The study goes on to conclude that BC’s revenue neutral carbon tax has reduced emissions with few negative effects on the economy. The Fletcher School is widely regarded as one of the world’s foremost graduate schools of international affairs.

By applying a price to carbon, industrial and consumer practices will change to lower cost, lower emissions options following market-driven cost-effective pathways. Recently, China launched the world’s largest cap and trade system. The decision to implement a carbon pricing mechanism in China was based on sound economic principals.

The Sask Party states that, over the next 5 years, a carbon tax would cost Saskatchewan $4 billion. This is simply erroneous, in that carbon taxes would raise $4 billion in revenues that would remain within the province. A revenue neutral carbon tax would see these funds dispersed to industry, the public and farmers.

By opposing carbon pricing, the Sask Party clearly has no intention of implementing well-established market based, cost-effective mechanisms to reduce emissions. An opposition to carbon pricing is, through inaction, a form of climate change denial.

Author, The Price of Carbon

March 4, 2018

I finished reading The Price of Carbon this morning and want to let you know that I really enjoyed reading it. More importantly I found it to be interesting, thought provoking and stimulating. It is very well researched, organized and written. I really appreciated your use of graphs and tables.

I found your treatment of climate change to be quite balanced. The status quo scenario certainly is a picture of gloom and doom for us all, but particularly for underdeveloped and island nations. Your book does not dwell unnecessarily on the problem, but instead is more focused on encouraging us to take action to slow down climate change for the sake of future generations. You describe a significant number of ways which we personally and collectively can slow climate change by decreasing the amount of green house gasses that we release into the atmosphere. Increasing the energy efficiency of our homes, using electricity produced without the burning of fossil fuels, eating much less meat from ruminant livestock and planting and maintaining more trees and forests are just a few of the ways individuals can contribute to the goal of slowing the progress of climate change. Unfortunately we have waited so long and the problem is so large that acting only on an individual basis will not have sufficient impact. It is essential that the nations of the world cooperate and each contribute significantly and ambitiously to drastically curtail the release of green house gasses. A few nations have already taken significant steps to decrease their carbon footprint. It is interesting that these steps have not resulted in the destruction of their economies, but instead appear to have made their countries better places to live. Unfortunately most countries have been very slow to act which will make it even harder to avoid the severe consequences of climate change for us all. The delays in action will make it necessary to implement ways to sequester atmospheric carbon dioxide in order to help slow the progress of climate change.

I am hopeful that one day your grandson will live in a world with fewer destructive climate events, improved air quality, less poverty, clean sufficient energy and less conflict.
