The Honor of Being Mugged by Climate Censors

Published by Wall Street Journal

Opponents of free debate are celebrating. Last week, under pressure from some climate-change activists, the University of Western Australia canceled its contract to host a planned research center, Australia Consensus, intended to apply economic cost-benefit analysis to development projects—giving policy makers a tool to ensure their aid budgets are spent wisely. The new center in Perth was to be a collaboration with a think tank I run, Copenhagen Consensus, which for a decade has conducted similar research. Working with more than 100 economists, including seven Nobel laureates, we have...

The surprising problem that is the greatest environmental danger to women and children

Published by New York Times - Women in the World

The world’s greatest environmental threat disproportionately harms women and children, particularly in the developing world: it is indoor air pollution. The World Health Organization estimates that indoor pollution kills 4.3 million people a year, mainly because 2.8 billion people still use firewood, dung and coal for cooking and keeping warm, breathing polluted air inside their homes every day. Indoor air pollution from cooking and heating with open fires can cause harm equivalent to smoking two packs of cigarettes a day.

The Right Health Investments

Published by Project Syndicate

West Africa’s Ebola epidemic has dominated headlines for much of the last year. But, as devastating as that outbreak has been, its death toll of less than 20,000 people is dwarfed by that of preventable diseases such as AIDS, tuberculosis, and malaria, which together caused more than three million deaths in 2013, hitting the world’s poorest people the hardest. This need not be the case; indeed, addressing these diseases would be an extraordinarily good investment.

It’s time to stop subsidizing fossil fuels

Published by Globe and Mail

Phasing out fossil fuel subsidies is an obvious target for the world’s next development goals. The world spends $548 billion subsidizing fossil fuels, mostly in developing countries. A disproportionate share of the subsidies goes to the middle class and the rich – after all, they are the ones who can afford a car in poor countries. Now is the time to cut fossil fuel subsidies. Thanks to plummeting oil prices, it is easier to reduce the subsidies needed to guarantee regulated consumer prices, taking off public pressure against such reforms. Cutting fossil fuel subsidies will help the...

The Price of Biodiversity

Published by Project Syndicate

Biodiversity - the species we share our planet with - is under pressure. Post-2015 Consensus research finds that a global target to prevent the loss of coral reefs will gives at least $24 of environmental benefits per dollar spent. Likewise, reducing the current loss of forests by half would likely do about $10 of good for each dollar spent. However, increasing protected areas, because it is very costly but only somewhat helpful, is likely to do less than $1 of good per dollar spent.

The spread of western disease: 'The poor are dying more and more like the rich'

Published by The Guardian

In rich countries, the biggest killers are strokes, heart attacks and cancer, accounting for more than two-thirds of all deaths. But for the poorer world, people often assume that infectious diseases like diarrhea, tuberculosis, Aids, malaria, measles and tetanus are the biggest killers. That is no longer true. While they are still substantial threats, broader availability of medication and vaccines along with higher living standards has caused such communicable diseases to drop dramatically to below 9 million deaths each year. For the first time, more people in the developing world now die...

Hur man löser klimatproblemet

Published by SvD Opinion

FN:s klimattoppmöte i Lima åstadkom inte särskilt mycket, i likhet med alla tidigare möten de senaste 20 åren. Som Albert Einstein sade: ”galenskap är att upprepa samma sak om och om igen och förvänta sig olika resultat”.

Soluciones inteligentes en seguridad alimentaria

Published by El Universo

Casi una cuarta parte de todos los alimentos en el mundo se pierde cada año en la ruta desde la recolección hasta el almacenamiento de desperdicios en la cocina del consumidor. En América Latina, más del 25% de todos los alimentos se desperdicia. Si pudiéramos reducir a la mitad los residuos de América Latina, el continente podría alimentar a 100 millones de personas más.

Electric car benefits? Just myths

Published by USA Today

It is time to stop our green worship of the electric car. It costs us a fortune, cuts little CO2 and surprisingly kills almost twice the number of people compared with regular gasoline cars.

Acciones para mejor gobernabilidad

Published by La Prensa

El año pasado, la corrupción le costó al mundo más de un billón de dólares (1). Es decir, un billón de dólares que no podemos utilizar para obtener una mejor atención sanitaria, educación, alimentación y cuidado del medio ambiente. Un estudio demuestra que la corrupción en Honduras le cuesta a cada ciudadano 592 dólares al año. Y la corrupción es sólo una parte del problema de la mala gobernabilidad -muchos países son administrados de forma ineficaz, sin rendición de cuentas, sin transparencia, ni un Estado de Derecho (2).
