As nations meet this week to work on an amendment to the Montreal Protocol to reduce hydrofluorocarbons (HFCs) -- one of the most potent greenhouse gases – a U.S. program is helping to reduce domestic emissions and demonstrate to other countries that there are practical, climate-friendly alternatives.
Hydrofluorocarbons, chemicals widely used in refrigeration, air conditioning, foam blowing, and other applications, were developed to replace ozone-depleting substances (primarily chlorofluorcarbons and hydrochlorofluorocarbons – CFCs and HCFCs) a few decades ago. But while HFCs don’t deplete the ozone layer, they do contribute to global warming, and, without policy intervention, their use is expected to grow dramatically over time.
National security leaders deal with deep uncertainty on a daily basis about everything from North Korea’s ability to produce a nuclear weapon to the location and timing of the next terrorist attack by non-state actors such as ISIS and al-Qaida. Security decision-makers don’t use uncertainty as an excuse to ignore security threats.
Borrowing a page from security analysts, a new report out today by renowned climate experts and high-level government advisors from China, India, the United Kingdom and the United States assesses the risks of climate change in the context of national and international security.
As many U.S. states start to think about ways to reduce greenhouse gas emissions under the proposed Clean Power Plan, it’s eye-opening to see how Chinese provinces are taking many of the same first steps.
I recently joined state officials from Arizona and Michigan and a Georgetown University professor on a study tour of China’s climate policy and low-carbon technology use at the provincial level. In each city we visited -- Beijing, Shanghai, Chengdu in Sichuan province, and Changsha in Hunan province -- our meetings with government officials, academics, and nongovernmental organizations had a common theme: Environmental issues are a serious challenge for China and greenhouse gases should be addressed along with other types of pollution.
It was very encouraging to hear national, provincial, and municipal leaders all agree that something has to be done to reduce China’s emissions. But they also agreed the country faces significant challenges in reaching its goal of peaking emissions no later than 2030.
Two years after President Obama announced his Climate Action Plan, the administration has taken at least initial steps on all 75 of its goals, according to a new C2ES status report.
The Climate Action Plan aims to reduce overall U.S. greenhouse gas emissions 17 percent below 2005 levels by 2020. While some steps in the plan are simple and within existing policies and programs, achieving some of the plan’s goals will require a transformation of the U.S. energy system over a period that will outlast President Obama’s time in office.
Federal and state measures beyond those in the plan will be needed to achieve the U.S. pledge to achieve a 26 to 28 percent reduction in U.S. emissions by 2025 as part of the effort to reach an international climate agreement.
We’re going solar!
Our middle-class, suburban family of five, with two children in college, two mortgages and a pile of other consumer debt, is getting a brand new, 7 kilowatt photovoltaic rooftop system worth roughly $31,000 – without us paying a penny out of pocket.
That’s right. We’re paying nothing upfront for the ability to generate up to one-third of the electricity our 1,500-square-foot split-foyer home would use in a typical month.
How’s that possible? With a power purchase agreement.
